[0001] The invention refers to a ground stabilizer for poles employ ing a shoe tool with
helical penetration, operating with gra dual compacting of the ground. The means substantially
permi ts - when the ground plane of base is foreseen for this purp ose has-been reached,
with transversal correspondence, integral with the said part of ground penetration
- to gradually increase the compactness of the retention ground while the spiral penetration
of the point is progressing. In this way, the laying of supports is permitted for
structures of line such as: poles for ducts, road stakes, uprights for plantations
and other, or for surface structures such as: enclosur= es, continuous walls or other,
thus obviating the present operations of digging and concrete mix casting.
[0002] Essential feature of the invention is the fact that the empl oy of the transversal
small base, when its contact with the ground has been reached, allows to operate the
ground compactness in progression when penetration of the helical point is going on.
This because, while the point is progressing, the quantity of ground in the penetration
wedge is increasing. The ground is compacting in the said space, and, with a gradual
progression, is exercising a gradual pressure effect by expansion from the ideal cylindrical
wall of the wedge on the surrounding ground, thus operating a total effect of the
pole stabilization.
[0003] For space of the penetration wedge with constant volume is to understand the one
included between the helical penetration t6 ol and having for base the section of
the penetration cavity and the upper stabilization base on the ground.
[0004] End stretchers of different kinds are at present used with he lical penetration for
camping: these are implements that oper ate.r.etention with penetration wedge, through
which the resis tance to slipping off is allowed by the natural ground compac tness.These
tension rods, which are generally used for tent pitching, do not allow the solution
of the problem of anchoring in grounds with limited consistency.
[0005] The invention permits the solution of the laying of line and surface structures at
ground plane by means of a device operating with penetration and gradual ground compactness,
princi pally allowing the stable placing into the ground of the stru cture and operating
without excavations and laying of foundations. Performing the rotation of the tool
in the inversed sen se, the total recovery of the structures is possible.
[0006] Version of execution and essential employ forms are illustrat ed in the drawings
of Table 1, where Fig. 1 is the perspective view of an implement according to the
invention. Fig. 2 is the view of the same in longitudinal section in driven in condition
into the ground to show the ground expansion in the penetratio n wedge, on the surrounding
one. Fig. 3 is the schematic view of a pole equipped with a tool at its bottom according
to the invention. Fig. 4 shows a pole applied axially on an similar device on stabilisation
ground. From Fig.5 a pole can be noted which is coaxially applied on an analogous
device on stabiliz ation ground. Fig.6 shows a set of poles applied on line for plantation
support. Fig.7 illustrates the employ of poles applied according to the invention
to be successively equipped with surface elements to form enclosure generic structures.In
a version, the implement of stabilization employs a rod spike 1 with penetration point
2 having a penetrating helical relief 3 at its lower end and upper ground compacting
plate 4 as well as through hole 5 for the transversal imposing bar 6 apt to bring
the spike in rotation for the imposing and disconnect! ng phases.
[0007] Version (a) is foreseen using pole la with base 2a, point 3a and helical part 4a
suitable for permitting poles to be direc tly stabilized in the ground. Version (b)
foresees a tool for stabilization in the ground with point lb, helical part 2b, base
3b and coaxial part in elevation 4b apt for integral ap plication of pole 5b by axial
introduction of its pin 6b and coaxial blocking to obtain by means of pin, screw or
other blocking part. Version (c) foresees another stabilization to ol in the ground
with point lc, helical part 2c and base 3c, with axial pin in elevation 4c useful
for the application of coaxial 5e, bottom end of the pole 6c and blocking of the two
parts by means of various devices.
[0008] The poles stabilized in the ground can operate as support of different transversal
structures such as: cables, plates or other connecting elements.
[0009] Practically, the execution particulars of the stabilization devices as well as of
the line and surface structures that can thus be laid on the ground plane can be foreseen
in different ways.The invention allows universality of employ for positioning structures
of different kinds on ground plane,to be laid or disconnected by merely rotating the
penetration rod in one sense or the other.
1) Stabilizer on the ground for poles, characterized by the fact" that it permits
laying line and surface structures at ground le vel by means of a stabilization device
with penetration throu gh helical point and upper transversal base integral with the
spike in order to determine a penetration wedge space. Continu ing the penetration
beyond the adhesion condition of the base to the ground, its compaction is obtained
in progression. This is possible because, when the spike is progressing, the quantity
of ground in the penetration wedge is increased and, the refore, a gradual expansion
of the mass contained in the rele vant space is obtained to determine a total effect
of ground compaction. In this way, the stabilization is attained of the pole integral
with such foundation device.
