Definitions

  • the present invention essentially relates to a method of anchoring in the ground of a prefabricated pile.
  • piles When it comes to installing piles in loose soil, piles can be used with an integral base made beforehand, because these piles will easily sink into the ground.
  • the present invention specifically aims to achieve the above objectives.
  • the invention relates to a pile according to claim 1.
  • the pipe used has a terminal portion with orifices which extends inside the recess and around which the bladder is arranged.
  • the pile according to this invention is further characterized in that the aforementioned end portion is removably connected, for example by screwing, to the pipe extending along the axis of the pile.
  • the pile comprises longitudinal reinforcing bars which extend into the wall of the aforementioned recess.
  • the bladder housed in the recess has a wall formed of foldable parts in the direction of the axis of this bladder.
  • a recess closure plate may also be provided at the lower end of the pile.
  • This pile P which is for example made of concrete, has at its lower part a recess 1 in which is housed a bladder 2 connected to a pipe 3 extending for example along the longitudinal axis of the pile P.
  • the pipe 3, as seen in FIG. 3, can be connected by its through end 4 to another pipe 5 itself connected to a pump 6 for injecting hardenable material, into the bladder 2.
  • the injected material can be any suitable material such as for example cement mortar, concrete or even a suitable resin.
  • the pipe 3 has an end portion 7 which is pierced with orifices and around which the bladder 2 is tightly fixed, which has the shape of a sheath.
  • the bladder can be made of any suitable material, such as woven or non-woven fabric or an elastically deformable synthetic material.
  • the bladder 2 as can be seen in FIG. 2, can have foldable portions on its periphery like an umbrella, so that when the bladder 2 is inflated by the material sent by the pump 6, the parts 2a initially folded open and the bladder or sheath 2 deploys completely along a diameter which is significantly larger than the initial diameter of the bladder in the folded position.
  • the terminal portion 7 of the pipe 3 it can be seen in FIG. 5 that it can be removably connected to the remaining part of the pipe 3 by means of a screw ring 9 for example.
  • the pipe 3 and its terminal portion 7 may for example be made of a suitable synthetic material, such as polyvinyl chloride, said terminal portion obviously being closed at 10.
  • the pile P has longitudinal reinforcing bars 11 which extend into the wall 12 defining the recess 1.
  • the pile P may include stirrups 13 like this is well known in itself.
  • the wall 12 of this recess may comprise externally, as can be seen in FIG. 2, notches 15 forming primers for breaking the lower part of the pile P under the effect of the inflation of the bladder or bag 2, as will now be described in a more detailed manner by explaining how the anchoring of the pile P takes place in the soil S.
  • the prefabricated pile P with its bladder 2 housed in the recess 1 is first introduced into the hole T, as seen in FIG. 1.
  • the bladder or bag 2 deploys and causes the radial deformation of the lower part of the pile P, that is to say of the wall 12 of the recess 1 .
  • This deformation can advantageously be carried out in a controlled manner, so that the wall 12 more or less bursts or breaks up in a manner substantially symmetrical with respect to the axis of the pile P, as can be seen in FIG. 4 .
  • the pile according to this invention can be made of concrete reinforced with metallic or other fibers, to make the deformation more symmetrical without risk of ruptures and present, in cross section, any shape, such as polygonal or cylindrical, being of course, the square shape visible in particular in Figure 2 should not be considered as limiting the scope of the invention.
