particularly relates to an auto-paver system with a measuring and positioning structure.
BACKGROUND
[0002] In a construction method of an immersed tube tunnel, it needs to excavate a base
groove at the water bottom first, then tube sections of the tunnel are sunk into the
pre-dredged base groove section by section, and the bottom surface of the base groove
serving as the foundation of the immersed tube section is uneven after being excavated
and formed, and backfilled stone is required to level the bottom surface, so that
the bearing capacity of the foundation is improved, and the related settlement is
controlled. As such, each tube section of the paved tunnel is uniformly stressed,
and the use effect is good.
[0003] In order to improve the smoothness of the bottom surface of the base groove, the
operation ship in the existing art generally adopts a floating leveling ship with
positioning piles or a platform leveling ship. The floating leveling ship and the
platform leveling ship with positioning piles generally include a distributing pipe,
the distributing pipe is directly penetrated into the water bottom, as the whole length
of the distributing pipe is long, the underwater part of the distributing pipe is
easy to be directly influenced by water flows and waves, so that the leveling accuracy
is reduced.

skill in that art can realize the technical proposal, when the combination of the
technical proposals occurs contradiction or cannot realize, it should consider that
the combination of the technical proposals does not existed, and is not contained
in the protection scope required by the present disclosure.
[0014] Referring to Figs. 1 to 8, an auto-paver system 100 with a measuring and positioning
structure proposed in this present disclosure includes a paver 10 including:
a support structure 11 supported on a water bottom surface;
a transport structure 13 slidably connected to the support structure 11; and
a distributing structure 155 connected to the transport structure 13 and having a
feed port 1551 and a discharge port 1553 through which materials pass, the discharge
port 1553 is extended towards the water bottom surface, the transport structure 13
is configured to drive the distributing structure 155 to move on the support structure
11, to lay materials through the discharge port 1553; and
the measuring and positioning structure 17 including a measuring frame 171 and at
least one positioning structure 173, one end of the measuring frame 171 is rotatably
connected to the support structure 11, and the positioning structure 173 is fixed
to the other end of the measuring frame 171.
[0015] The support structure 11 of the auto-paver system 100 according to the technical
scheme of the present disclosure is supported on the water bottom surface, and the
transport structure 13 is slidably connected to the support structure 11. The support
structure 11 can limit a movement track of the transport structure 13 and enable the
transport structure 13 to move relatively close to the water bottom surface. The distributing
structure 155 is connected to the transport structure 13, so that the distributing
structure 155 can also move at a position close to the water bottom surface under
the drive of the transport structure 13. Materials are input through the feed port
1551 of the distributing structure 155 and output through the discharge port 1553,
and the discharge port 1553 is extended towards the water bottom surface. As the distributing
structure 155 is close to the water bottom surface, the materials output by the distributing
structure 155 can fall to a designated position of the water bottom surface through
a short distance, and the whole laying process is hardly influenced by water flows,
so that the laying position of the materials on the water bottom surface is accurate.
[0016] Furthermore, the support structure 11 is also provided with a measuring and positioning
structure 17. The positioning structure 173 of the measuring and positioning structure
17 is used for acquiring self position information of the measuring and positioning
structure 17. Position information of the support structure 11 can be obtained by
combing the self position information with the known form of the measuring frame 171,
and the support structure 11 can be accurately placed at a designated position according
to the obtained position information of the support structure 11, so that the distributing
position of the distributing structure 155 is more accurate.
[0017] The measuring frame 171 is rotatably connected to the support frame 11, so that an
overall height of the measuring and positioning structure 17 can be adjusted, thereby
achieving the purpose of not occupying the navigation channel.
[0018] Specifically, the measuring frame 171 is configured to rotate relative to the support
structure 11 to have a first state and a second state, the positioning structure 173
on the measuring frame 171 in the first state is higher than the positioning structure
173 on the measuring frame 171 in the second state. In the first state, the detection
effect of the positioning structure 173 is more accurate, and in the second state,
the overall height of the measuring and positioning structure 17 is reduced, so that
the paver 10 achieves the purpose of less or no obstruction to the navigation channel.
[0019] In one embodiment of the present disclosure, the measuring frame 171 includes at
least one upright post 1711, one end of the upright post 1711 is rotatably connected
to the support structure 11, and the positioning structure 173 is fixed to the other
end of the upright post 1711.
[0020] The positioning structure 173 supported by the upright post 1711 can be extended
by a certain distance, so that the positioning structure 173 is close to the water
surface or extended out of the water surface, so that the positioning structure 173
is less interfered by underwater, and the positioning is accurate.
[0021] Referring to Figs. 1 and 2, in one embodiment of the present disclosure, the upright
post 1711 is provided with a first connecting piece 172, the first connecting piece
172 is provided with a first connecting hole, the support structure 11 is provided
with a second connecting piece 182 matched with the first connecting piece 172, the
second connecting piece 182 is provided with a second connecting hole matched with
the first connecting hole, and a pin shaft 121 is passed through the first connecting
hole and the second connecting hole matched with the first connecting hole to rotatably
connect the upright post 1711 and the support structure 11. Under the restriction
of the pin shaft 121, the upright post 1711 can rotate relative to the support structure
11, and the rotating structure is simple.
[0022] In one embodiment of the present disclosure, the paver 10 further includes a limiting
structure, which is configured to limit and fix the upright post 1711 and the support
structure 11 when the upright post 1711 is rotated to form an included angle with
the support structure 11.
[0023] Specifically, the upright post 1711 is rotatably connected to a side of the support
structure 11 facing away from the water bottom surface. Therefore, the upright post
1711 is rotated only on the side of the support structure 11 facing away from the
water bottom surface during the rotation of the support structure 11. The upright
post 1711 is rotated to form an included angle with the support structure 11, which
is greater than zero, that is, the position where the positioning structure 173 is
located is relatively high with respect to the water bottom surface. In this state,
the positioning detection effect of the positioning structure 173 is better, that
is, the first state is reached. When the angle between the upright post 1711 and the
support structure 11 is zero, that is, it is measured that the whole positioning structure
17 is at a lowest position with respect to the water bottom surface. In this state,
the paver 10 can be completely accommodated in the base groove to reach the second
state without blocking the navigation channel.
[0024] In one embodiment of the present disclosure, the limiting structure includes a third
connecting piece 174 arranged on the upright post 1711 and a fourth connecting piece
184 arranged on the support structure 11, the third connecting piece 174 is provided
with a third connecting hole, the fourth connecting piece 184 is provided with a fourth
connecting hole matched with the third connecting hole, a bolt 123 is detachably passed
through the third connecting hole and the fourth connecting hole, to detachably connect
the upright post 1711 and the support structure 11, and when the upright post 1711
is rotated to form an included angle with the support structure 11 the bolt 123 is
configured to limit and fix the upright post 1711 and the support structure 11.
[0025] When the bolt 123 is passed through the third connecting hole and the fourth connecting
hole, to limit the upright post 1711 and the support structure 11, so that the bolt
123 is configured to fix the upright post 1711 and the support structure 11 when the
upright post 1711 is rotated to form an included angle with the support structure
11.
[0026] Referring to Figs. 3 and 4, in one embodiment of the present disclosure, the third
connecting member 174 is disposed at an end of the upright post 1711 remote from the
positioning structure 11, and the rotating joint between the upright post 1711 and
the support structure 11 is spaced apart from the third connecting member 174 along
a length direction of the upright post 1711.
[0027] Specifically, when the upright post 1711 is rotated to a plane perpendicular to the
support structure 11, the end of the upright post 1711 is fixed by the limiting structure
to reach the first state. An axial direction of the bolt 174 of the limiting structure
is consistent with an axial direction of the upright post 1711. A portion of the upright
post 1711 near the limiting structure is rotatably connected with the support structure
11. Specifically, the rotating shaft of the upright post 1711 is perpendicular to
the axial direction of the upright post 1711, that is, the axial direction of the
pin shaft 121 is perpendicular to the axial direction of the upright post 1711.
[0028] An opening is formed at the end of the upright post 1711 remote from the positioning
structure 173, the opening is extended along the axial direction of the upright post
1711, the third connecting plate 174 is defined as two parallel plates, the plate
surfaces of the two plates are perpendicular to the axial direction of the upright
post 1711, one plate is positioned in the opening, the other plate is configured to
block the opening, and the two plates are provided with a third connecting hole, the
two connecting holes are matched with each other. The support structure 11 is provided
with a fourth connecting plate 174 perpendicular to the axis of the upright post 1711
when the upright post 1711 is rotated to be perpendicular to the support structure
11. The bolt 174 is passed through the fourth connecting hole and the two third connecting
holes along the axis direction of the upright post 1711. The limiting structure can
limit the rotation of the upright post 1711 on the support structure 11.
[0029] When the bolt 174 on the limiting structure is pulled away, the upright post 1711
can rotate on the support structure 11 to make the measuring and positioning structure
17 to be in a lower position.
[0030] In one embodiment of the present disclosure, the measuring and positioning structure
17 includes two positioning structures 173, the measuring frame 171 includes two upright
posts 1711 which are oppositely arranged, a connecting bracket 1713 is connected between
the two upright posts 1711, and the two positioning structures 173 are respectively
fixed to the two upright posts 1711.
[0031] Under the common positioning of the two positioning structures 173, the obtained
position of the support structure 11 is more accurate, and the two upright posts 1711
are connected by the connecting bracket 1713, so that the two upright posts 1711 of
the measuring frame 171 can rotate relative to the support structure 11 at the same
time, and the structure is simple.
[0032] In one embodiment of the present disclosure, the connecting bracket 1713 includes
a connecting beams 1713a connected with two upright posts 1711. A quantity of the
connecting beams 1713a is two, and the two connecting beams 1713a are arranged in
parallel.
[0033] The two connecting beams 1713a can connect the two uprights 1711 well, so that the
two uprights 1711 can rotate at the same time, and the structure is simple.
[0034] In one embodiment of the present disclosure, the connecting bracket 1713 further
includes a plurality of reinforcing rods 1713b, and the reinforcing rods 1713b are
connected to an area enclosed by the two upright posts 1711 and the two connecting
beams 1713a.
[0035] As the two upright posts 1711 are arranged in parallel with each other and the two
connecting beams 1713a are arranged in parallel with each other, a rectangular area
is formed between the two upright posts 1711 and the two connecting beams 1713a, and
the connection between the two upright posts 1711 is more stable due to the arrangement
of the reinforcing rods 1713b.
[0036] Referring to Fig. 3, a connecting plate is fixed at each joint of the two upright
posts 1711 and the connecting beam 1713a adjacent to the positioning structure 173.
One connecting plate is fixed at the middle of the other connecting beam 1713a. There
are three reinforcing rods 1713b. Both ends of each reinforcing rod 1713b are connected
to two connecting plates located on the two connecting beams 1713a. Therefore, the
reinforcing bar 1713b can divide the rectangular area into a plurality of triangular
areas. Based on the stability of the triangles, the arrangement of the reinforcing
bar 1713b can make the connection of the two upright posts 173 more stable and reliable.
[0037] In one embodiment of the present disclosure, the support structure 11 includes a
support frame 113 and a buoyancy column 18, the support frame 113 is supported on
the water bottom surface, the buoyancy column 18 is convexly arranged on one side
of the support frame 113 facing away from the water bottom surface, the transport
structure 13 is slidably connected to the support frame 113, and the measuring frame
171 is rotatably connected to the buoyancy column 18.
[0038] The buoyancy column 18 is convexly arranged on one side of the support frame 113
facing away from the water bottom surface, so that the measuring frame 171 rotatably
connected to the buoyancy column 18 is lifted by a distance in the direction facing
away from the water bottom surface, so that when the measuring frame 171 is rotated
to form a zero degree included angle with the support structure 11, the measuring
frame 171 can abut against an end surface of the buoyancy column 18, so that the whole
measuring and positioning structure 17 and the support frame 113 maintain a certain
distance, and the measuring and positioning structure 17 cannot interfere with the
transport structure 13 and the distributing structure 155 moving on the support frame
113. The buoyancy column 18 is a hollow cylinder, which has a certain floating effect
on the underwater support structure 11, thus reducing the total weight of the support
structure 11 and facilitating the change of the position of the support structure
11.
[0039] When the upright post 1711 is rotated to the first state, the upright post 1711 rotates
until the axial direction of the upright post 1711 is consistent with the axial direction
of the buoyancy column 18, and the upright post 1711 and the buoyancy column 18 partially
overlap along the axial direction. One end of the upright post 1711 facing away from
the positioning structure 173 is detachably connected to the buoyancy column 18 through
the limiting structure, so that the positioning structure 173 positioned at the end
of the upright post 1711 can reach the highest position. A portion of the upright
post 1711 near the limiting structure is rotatably connected to a free end of the
buoyancy column 18, and the free end is an end of the buoyancy column 18 facing away
from the support frame 113. By pulling out the bolt of the limiting structure, one
end of the upright post 1711 facing away from the positioning structure 173 is separated
from the buoyancy column 18. The upright post 1711 is rotated to abut against the
free end of the buoyancy column 18 and is parallel to the plane where the support
structure 11 is located, to reach the second state. It is measured that the overall
height of the positioning structure 17 is decreased, so that the paver 10 is integrally
accommodated in the base groove.
[0040] In one embodiment of the present disclosure, in the first state, one end of the upright
post 1711 fixed with the positioning structure 173 is extended out of the water surface,
so that the positioning effect of the positioning structure 173 is better.
[0041] The positioning structure 173 is a GPS (Global Positioning System), specifically,
a RTK (Real-time kinematic, Carrier Phase Difference Technology). The RTK can provide
three-dimensional positioning results of the measured position in a specified coordinate
system in real time and achieve centimeter-level accuracy. So that, the obtained position
information of the support structure 11 is more accurate.
[0042] The support frame 113 includes two opposite first crossbeams 1131 and two opposite
second crossbeams 1133. The first crossbeams 1131 and the second crossbeams 1133 are
connected end to end. There are four buoyancy columns 18. Each buoyancy column 18
is arranged at one joint of the first crossbeam 1131 and the first second crossbeams
1133. The measuring structure 171 is rotatably connected to the two buoyancy columns
18 which are positioned on the same side. The support frame 113 also includes a plurality
of support legs 16. The plurality of support legs 16 are symmetrically connected to
the two first crossbeams and/or the two second crossbeams, and are supported on the
water bottom surface. The first crossbeams 1131 and/or the second crossbeams 133 are
provided with guide rails 111, and the transport structure 13 is slidably connected
to the guide rails 111.
[0043] The paver 10 is supported on the water bottom surface by the support leg 16, and
can directly perform laying and paving work under water. While the work platform of
the existing floating leveling ship or the platform leveling ship with positioning
piles is located on or above the water surface, and partial structural of the leveling
ship needs to be adjusted according to the water depth. The auto-paver system 100
of the present disclosure can be suitable for requirements of different water depths,
and has wide applicability.
[0044] The support leg 16 includes a driving part 162, a leg 161, and a connecting part
163. The driving part 162 is configured to drive the leg 161 and the connecting part
163 to move relative to each other in an up-down direction, so that the height of
the support structure 11 on the water bottom surface can be adjusted, and the height
of the distributing structure 155 on the water bottom surface can be adjusted, so
that the distributing structure 155 can be applied to the bottom surfaces of the base
grooves with different concavities and convexities, and the applicability range of
the auto-paver system 100 of the present disclosure is wider.
[0045] Under the adjustment of the support leg 16, the distance between the lower surfaces
of the first crossbeam 1131 and the second crossbeam 1133 and the water bottom surface
is in a range of 800 mm to 2800 mm, so that a distance between the discharge port
1553 of the distributing structure 155 and the water bottom surface is in a range
of 0 mm to 2000 mm. In this size range, when the auto-paver system 100 works, the
paver 10 is close to the water bottom surface, so that the transport structure 13
slidably connected to the support frame 113 and the distributing structure 155 connected
to the transport structure are close to the water bottom surface, and the material
transported by the distributing structure 155 during the movement of the support frame
113 is short, so that the output process is less affected by water flows and the laying
is accurate. That is, under the adjustment of the support leg 16, the distance between
the support frame 113 and the water bottom surface (that is, the bottom surface of
the base groove) can be adjusted between 800 mm and 2800 mm, so that the distance
between the discharge port 1553 of the distributing structure 155 and the water bottom
surface can be adjusted between 0 mm and 2000 mm.
[0046] The guide rail 111 can restrict the transport structure 13 to move along a certain
track, so that the material distribution structure 155 can evenly lay the material
in the area where the guide rail 111 can reach. The structure and shape of the guide
rail 111 determine the laying trajectory of the distributing structure 155. The structure
and shape of the guide rail 111 can be changed according to different requirements,
so that the auto-paver system 100 can adapt to different working requirements. The
rationality of the arrangement of the guide rail 111 can affect the smoothness of
gravel laying on the water floor. Therefore, under the restriction of the guide rail
111, the track traveled by the transport structure 13, the shape of the discharge
port 1553 of the distribution structure 155 and the amount of the laying material
need to be well matched, so that the water bottom surface to be laid can achieve a
required forming effect.
[0047] In one embodiment of the present disclosure, the guide rail 111 is disposed on the
second crossbeam 1133, the transport structure 13 is slidably connected to the guide
rail 111, and the support legs 16 are symmetrically connected to the two second crossbeams
1133.
[0048] Each support leg 16 can be adjusted separately, so that the height of the position
where any support leg 16 is connected to the support frame 113 can be adjusted separately,
thereby controlling the inclination angle of the support frame 113.
[0049] As the guide rail 111 is arranged on the second crossbeam 1133, the transport structure
13 and the distributing structure 155 are mainly carried by the second crossbeam 1133.
So that, the support leg 16 is connected to the second crossbeam 1133, and the load-bearing
capacity of the second crossbeam 1133 is stronger, the transport structure 13 and
the distributing structure 155 can maintain high consistency during their movements
on the guide rail 111, and the paving effect of the distributing structure 155 is
better.
[0050] In one embodiment of the present disclosure, the guide rail 111 includes two symmetrically
arranged longitudinal guide rails 1111 and two symmetrically arranged transverse guide
rails 1113, the longitudinal guide rails 1111 are arranged in parallel with the first
crossbeam 1131, and the transverse guide rails 1113 are arranged in parallel with
the second crossbeam 1133. Referring to Fig. 1, in one embodiment, two symmetrically
arranged transverse guide rails 1113 are respectively fixed to two second crossbeams
1133, and two longitudinal guide rails 1111 are slidably connected to the two transverse
guide rails 1113. Specifically, one end of each longitudinal guide rail 1111 is slidably
connected to one transverse guide rail 1113, and the other end of each longitudinal
guide rail 1111 is slidably connected to another transverse guide rail 1113. The second
crossbeam 1133 is provided with a drive motor and a chain arranged along an extension
direction of the second crossbeam 1133. The chain is connected with the two longitudinal
guide rails 1111. Under the drive of the motor, the chain is configured to drive the
longitudinal guide rails 1111 to reciprocate along the transverse guide rails 1113
(i.e., to reciprocate along the extension direction of the second crossbeam 1133).
It can be understood that the longitudinal guide rail 1111 can also be slidably connected
to the transverse guide rail 1113 by other driving means, for example, a roller and
a driving structure provided on the longitudinal guide rail. The driving structure
is configured to drive the roller to roll on the transverse guide rail, so that the
longitudinal guide rail can slide relative to the transverse guide rail on the transverse
guide rail.
[0051] Before laying materials, or when the auto-paver system 100 restarts after a half-stopping,
sludge may accumulate on the bottom surface of the base groove due to the influence
of water flows. A sludge suction structure 145 needs to be arranged on the transport
structure 13 to suck sludge, so as to prevent sludge from being mixed with crushed
stones and affecting the supporting effect of the bottom surface of the base tank
on the sinking pipe.
[0052] Referring to Fig. 6, in one embodiment of the present disclosure, the paver 10 further
includes a sludge suction structure 145 connected to the transport structure 13, the
sludge suction structure 145 is provided with a sludge discharge port 1453 and a sludge
suction port 1451 extending in the direction towards the water bottom surface, and
is provided with a sludge suction driving member communicating the sludge suction
port 1451 and the sludge discharge port 1453.
[0053] The sludge suction port 1451 of the sludge suction structure 145 is extended towards
the water bottom surface. The transport structure 13 is configured to move along the
guide rail 111 and drive the sludge suction structure 145 to move to the position
where sludge needs to be sucked. The sludge suction driving member is turned on, submerged
sludge is entered into the sludge suction structure 145 through the sludge suction
port 1451 and is discharged through the sludge discharge port 1453 to remove the accumulated
sludge and prepare for paving work.
[0054] In one embodiment of the present disclosure, the auto-paver system 100 includes a
workbench 30 arranged on the water surface, the workbench 30 is provided with a main
controller (not shown), the main controller is electrically connected with the transport
structure 13, to control the transport structure 13 ito drive the distributing structure
155 to move on the support structure 13 and lay materials through the discharge port
1553;
[0055] The main controller is electrically connected to the positioning structure 173 to
acquire the position information obtained by the positioning structure 173.
[0056] The main controller is configured to calculate the position information of the support
structure 11 according to the position information acquired by the positioning structure
17, so that the external structure can be controlled to place the support structure
11 at a specified position.
[0057] The measuring frame is rotatably connected to the support frame 113, and the main
controller can be electrically connected to the measuring frame to control the measuring
frame to rotate relative to the support frame 113, so that the measuring frame is
extended out of the water surface or is folded on the support frame 113. When the
auto-paver system 100 stops working in the middle, the main controller controls the
measuring frame to fold on the support frame 113, so that the measuring frame does
not obstruct the navigation channel when the auto-paver system 100 stops working,
and when the auto-paver system 100 starts running again, the main controller controls
the measuring frame to extend out of the water surface to position the support frame
113. It is understood that the support positioning structure 17 can also be rotatably
covered on the support structure by an external structure.
[0058] Workers operate the transport structure 13 on the workbench 30, which can automatically
control the auto-paver system 100, for reducing the underwater workload of workers
and ensuring the personal safety of workers.
[0059] Referring to Fig. 6, in one embodiment of the present disclosure, the auto-paver
system 100 further includes a blanking hopper 151 and a distributing pipe 153, the
blanking hopper 151 is arranged on the workbench 30, one end of the distributing pipe
153 is communicated with the blanking hopper 151, and the other end of the distributing
pipe 153 is communicated with the feed port 1551 of the distributing structure 155.
[0060] The materials in the blanking hopper 151 can slide down the distributing pipe 153
into the distributing structure 155 under the action of gravity only, and finally
fall to the bottom surface of the base groove from the discharging port 1553 of the
distributing structure 155. Understandably, the blanking hopper 151 may be provided
with a power structure to accelerate the falling of materials.
[0061] The main controller is configured to control the amount of material dropped into
the distributing pipe 153 by the blanking hopper 151, thereby controlling the amount
of material discharged from the distributing structure 155 through the distributing
pipe 153; or the main controller directly is configured to control the discharging
amount of the discharging port 1553 of the distributing structure 155. The workers
can control the discharge amount of materials by operating the main controller on
the workbench 30. Combined the control of the main controller on the running track
of the transport structure 13, the distributing structure 155 can evenly lay materials
on the water bottom surface. When the paver 10 of the auto-paver system 100 performs
laying work, the lower end of the distributing pipe 153 is driven by the distributing
structure 155 to move, while the upper end of the distributing pipe 153 is connected
to the blanking hopper 151 on the water surface without moving, so the paver 10 is
less affected by water flows during paving.
[0062] The distributing structure 155 is also provided with an underwater camera, which
is electrically connected to a detection screen (not shown) on the workbench 30. During
the operation of the auto-paver system 100, the worker can observe the height of the
materials stored in the distributing structure 155 through the detection screen on
the workbench 30, so as to better operate the main controller and adjust the blanking
amount of the blanking hopper 151.
[0063] In one embodiment of the present disclosure, the auto-paver system 100 further includes
a sludge suction pipe 143 and a storage structure 141 arranged on the workbench 30.
One end of the sludge suction pipe 143 is communicated with the sludge discharge port
1453 of the sludge suction structure 145, and the other end of the sludge suction
pipe 143 is communicated with the storage structure 141. The main controller is electrically
connected with the sludge suction driving member, to control the sludge suction structure
145 to suck sludge on the water bottom. The sludge suction driving member is a hydraulic
pump, and the transport structure 13 moves on the support frame 113 to transport the
sludge suction structure 145 to a designated position for sludge suction. The lower
part of the suction pipe 143 is driven to move by the suction structure 145 while
the upper part of the suction pipe 143 is fixed to the storage structure 141 during
the suction process of the suction structure 145, keeping the position unchanged,
and the suction process is hardly affected by water flow.
[0064] Referring to Figs. 7 and 8, in one embodiment of the present disclosure, the auto-paver
system 100 further includes a retraction structure 50, the retraction structure 50
includes a driving piece 51 and a connecting piece 53 connected with the driving piece
51, the driving piece 51 is connected with the workbench 30, the connecting piece
53 is detachably connected with the support frame 113, the main controller is electrically
connected with the driving piece 51, to control the driving part 162 to move to a
specified position of the support frame 113 when the connecting piece 53 is connected
with the support frame 113.
[0065] When the paver 10 of the auto-paver system 100 completes a paving operation, the
connecting piece 53 of the retraction structure 50 is connected to the support frame
113 by a manual operation or under a control of the main controller. The driving piece
51 is configured to drive the connecting piece 53 to lift the support frame 113 from
the water bottom until the measuring positioning structure 16 leaves the water bottom
for a distance, and moves the support frame 113 to a next area to be paved, and then
sinks the support frame 113 to the water bottom until the measuring positioning structure
16 is supported on the water bottom surface of the next area to be paved. The connecting
piece 53 is separated from the support frame 113 by the manual operation or under
the control of the main controller. The paver 10 performs the next paving operation.
[0066] The auto-paver system 100 adopts automatic operation, so that workers can operate
and monitor the underwater paving work on the working table 30 on the water, almost
no underwater operation is needed, thus ensuring the safety of workers, and the automatic
control process enables the auto-paver system 100 to have high construction efficiency
for underwater paving.
[0067] Referring to Figs. 2 and 3, the driving member 51 of the retraction structure 50
can be a motor and is installed on the workbench 30. The connecting member 53 can
be a steel cable, one end of the steel cable is connected to the motor and the other
end of the steel cable is submerged by a worker and tied to the support frame 113
of the support structure 11. The main controller is configured to control the starting
motor to lift the support structure 11 for a certain distance through the steel cable,
then after the workbench moves for a certain distance along the length direction of
the base groove the main controller is configured to control the motor to drive the
steel cable to sink the support frame 113 in the next area to be paved.
[0068] Understandably, the connecting piece 53 can also be a connecting frame. The main
controller is configured to control the driving piece (motor or air cylinder) to combine
with the positioning structure to provide the positioning information, to control
the connecting frame to automatically extend to the position where the support frame
113 is located. The connecting frame is manually fixed to the support frame 113 through
bolts, screws or snap structures, or the connecting frame is automatically fixed to
the support frame 113 under the control of the main controller. Under the further
control of the main controller, the connecting piece 53 is configured to move the
support frame 113 to the next area to be paved.
[0069] In one embodiment of the present disclosure, the distributing structure 155 is further
provided with a detection piece (not shown), which is configured to detect flat value
information of the water bottom surface, and detect the flat degree of the area to
be paved on which the material has been laid, and feed back the result to the main
controller for further work.
[0070] The workbench 30 may include a first workbench 31, a second workbench 33, and a third
workbench 35. The first workbench 31 is configured to set the main controller and
the blanking hopper 151. The main controller is configured to control all the required
