OBJECT OF THE INVENTION
[0001] The present invention relates to a module for retaining earth, envisaged preferably
and mainly to build the classic breakwaters, walls for retaining earth placed in staggered
terrains and terraces, also being applicable at the coast to prevent the erosion of
the water on the earth, the river banks, etc.
[0002] The object of the invention is to obtain an easy-to-make retaining wall having optimal
stability, preventing the movement of the parts making it up, and therefore withstanding
the force that could be exerted by the earth when it shifts.
[0003] Although it has been previously said that the retaining wall is envisaged for breakwaters,
river banks, terrace-type staggering for example, it can be applicable in any circumstance
where the retaining of earth is desired to be carried out, whether stable or not,
as well as for public works and other buildings works.
BACKGROUND OF THE INVENTION
[0004] Normally, the retaining walls are made based on large stone blocks placed forming
an inclined wall in correspondence with the inclination of the terrain, so these stones
are placed in the attempt they 'marry' each other in the best way possible, being
affixed to one another by means of mutual friction.
[0005] Among the problems and inconveniences presented by this type of construction of retaining
walls, we have the following:
- the stone blocks work by friction, as indicated above.
- There is a notable actual weight of the retaining wall.
- In principle, the technician cannot known with certainty if the operative on site
will be able to choose the appropriate stone blocks and arrange them in the most suitable
position for their unification.
- The reliability in the obtaining of the survey according to the execution project
is not always appropriate.
- The resources necessary for carrying out these works are very expensive and burdensome.
- The need to look for natural stone blocks generates an additional difficulty, added
to the well-known deterioration of the environment.
- It should be noted that highly qualified technicians must permanently control the
execution of the work.
[0006] Well, part of the problems and inconveniences indicated above are solved by using
pre-manufactured stones made from concrete instead of the classic natural stone blocks,
although the inconvenience that the blocks are linked to one another by means of friction,
that is to say, that they work by friction, still remains, as well as the elevated
costs to execute the work, and, of course, the control of the execution thereof.
DESCRIPTION OF THE INVENTION
[0007] The wall for retaining earth proposed has been conceived to solve the problems indicated
above, based on the use of hollow interlocking male-female plastic pieces which, once
mounted in a simple manner due to their low weight, can be filled with concrete, even
allowing the introduction of steel frameworks through said pieces, thus reinforcing
the mechanical strength of the wall, instead of the classic natural stones or pre-manufactured
concrete blocks.
[0008] More specifically, the wall is constituted from a foundation, which can be straight,
winding, curved, straight-angled, cornered, buttresses and pilasters, etc. according
to the characteristics of the terrain, so, on said initial foundation, different rows
of modules with a male-female interlocking among them are placed, making it impossible
for the same to move horizontally due to the pressure of the earth.
[0009] On the original foundation, a first row based on foundation plates, constituted by
triangle-shaped structures wherein they are established is placed, in correspondence
with two of the vortexes, two hollow, cylindrical bodies, while on the other vortex
there is a slightly smaller oval part, these foundation plates being conveniently
joined with one another on the original foundation in such a way that on top of this
row of foundation plates, a first row of base modules is mounted, which are likewise
hollow and have a cylindrical foot connectable to one of the cylindrical housings
of the foundation plate, so these foundation plates that would constitute the first
row present an inclined plane in their front side that is variable according to the
slope necessary to constitute the facing side of the retaining wall, which can vary
in shape and colour according to the project planner, while incorporating a pair of
horizontal protrusions in its rear side, whose function will be exposed below.
[0010] Once this first row of foundation modules is mounted, a second row of other modules
is placed, with the same characteristics as the previous ones but, instead of having
a cylindrical foot for its overlapping in one of the cylindrical bodies of the foundation
plate, it presents a longer yet narrower cylindrical foot for its coupling to the
hollow and oval body established in the foundation plate and in the triangle-shaped
structure located on the original foundation, so this elongated yet narrower cylindrical
body passes behind the foundation module of the first row.
[0011] After the mounting of the second row of foundation modules, another row of modules
of the type is mounted, with similar characteristics to the two referred above, but
instead of the cylindrical body, they include a lower extension in the form of an
inverted "T", positioned in a fitted manner between the projections constituting the
horizontal and rear protrusions of the foundation modules of the first row, thus establishing
a male-female coupling preventing the relative displacement between modules, both
in the horizontal and vertical directions.
[0012] The modules forming the wall constituted in this manner may have flat lateral sides
when the retaining wall is straight, but said sides can have an angular or other configuration
in order to make curves in the trajectory of the wall, which may be concave or convex.
[0013] The constructive system based on which the wall is obtained, according to the invention,
allows the dismounting of the different modules by only using supporting pads between
modules in order to free them during dismounting.

PREFERRED EMBODIMENT OF THE INVENTION
[0015] As seen in the referred figures, the retaining module object of the invention is
obtained by means of the male-female mounting or assembly of a series of modules and
elements among each other, which will be exposed throughout the present description,
all of which from a foundation (1) on the terrain, wherein, in the first place, there
is a base constituted by means of the integration of foundation plates (2) among each
other, defining a triangle-shaped structure wherein two of its vortexes are determined
by hollow, cylindrical bodies (3), and the other vortex is formed by an oval, narrower
body (4), also hollow, so said foundation plates (2) are arranged on the foundation
(1) carried out for said purpose, in such a way that the foundation plate (2) and
the remaining modules participating in the wall are made from plastic, are hollow
and are able to receive concrete and metal frameworks to give said set the necessary
mechanical strength after being mounted.
[0016] Well, on this base formed by the foundation plates (2), a series of foundation modules
(5) are mounted, which will constitute a first row, also formed by hollow bodies,
with a cylindrical lower extension or projection (6) intended to be housed in one
of the cylindrical parts of bodies (3) of the foundation plate (2), allowing the rotation
of the module (5) to be placed conveniently.
[0017] After the first row formed by the modules (5) referred to above, the arrangement
of a second row based on modules (5') with similar characteristics than the modules
(5) takes place, presenting longer, narrower projections (6') instead of the cylindrical
projections (6), intended to be arranged after the modules (5) and to be coupled,
by their lower extremity, to the oval bodies (4) of the foundation plate (2), as seen
in the explosion view of figure 9.
[0018] After the arrangement of these modules (5') of the second row, it could be said that
the foundation is made, next arranging another row of modules of the type (7), which
are also hollow and are provided with a pair of rear protrusions (8) and a lower extension
in an inverted "T" (9), presenting its inclined front plane (10), as clearly shown
in figure 2, wherein the cavities (11) presented by the body constituted the aforementioned
module (7) can be observed.
[0019] Regarding the base modules (5), in addition to the lower cylindrical projection (6)
and its corresponding inclined plane (13) in its frontal side, they includes a pair
of rear projections or protrusions (12), characteristics that are repeated in the
module (5'), with its frontal and inclined side (13'), its rear projections or protrusions
(12'), and its elongated and oval projection (6').
[0020] Therefore, the embodiment of the retaining wall is carried out by firstly arranging
the foundation plates (2) on the foundation (1), and on said plates, the modules (5)
that are to form the first row, connecting the lower cylindrical projections (6) thereof
to the cylindrical bodies (3) of the plates (2), in order to then form the second
row with the modules (5'), connecting the oval and elongated projections (6') to the
oval bodies (4) of the plates (2); with the arrangement of these oval and elongated
projections (6') of the modules (5'), behind the modules (5), to finally have the
modules of the type (7), whose rear projections or protrusions (8) are arranged in
an interlocking manner, as in a male-female coupling, between the rear projections
(12 and 12') of the modules (5 and 5'), all of which without the existence of the
possibility of inter-module movement, both horizontally and vertically.
[0021] Finally, it should be said that in order to enable dismounting, supporting pads (14)
between modules have been provided, as clearly shown in figure 3, in such a way that,
based on these pads (14), the dismounting of the different modules and therefore the
retaining wall can be carried out easily, in the case that said dismounting must take
place due to need or due to any other circumstance.
