Definitions

  • the invention relates to a device for shoring a wall of excavation support, especially for construction sites, and particularly suitable for use in seismic zones.
  • the anchors are high-tech works using steel prestresses and a sealing zone. This setting complex and expensive work requires the complex phasing of earthworks and may be impossible due to the presence of structures (pipeline, tunnels, cellars, etc.).
  • the struts are generally made of metal and their presence between the walls obstructs the excavation, making it difficult to carry out the work later such as earthworks or structural work.
  • this solution requires bracing and intermediate supports, for example pre-ground posts, and because of their elasticity, problems of expansion and / or temperature-related deformation may require processing complex such as the use of preloads, cylinders to accumulation, reflective paints, etc .... This solution therefore limits access to the search due to the presence of a tangle of struts can also cross at different heights.
  • the object of the invention is to solve at least one of the problems discussed above.
  • the invention provides for using at least one strut associated with a rigid support structure which frees up an area of work in its center in order to gain easier access to the interior of the excavation.
  • the subject of the invention relates to a device shoring of an excavation retaining wall defining an interior of excavation limited by this wall, said device comprising at least one strut of stabilization having two ends to bear against said wall at level of a first end, in which at least one rigid structure support, is intended to be arranged inside the excavation.
  • a stabilization strut by the opposite end to the first end, so that said structure is close enough to the excavation wall to define a workspace free access.
  • the rigid support structure is made of material making it removable, for example of materials composites.
  • all of the stabilization struts exert a centripetal compressive force on the rigid support structure.
  • the struts are arranged all around the rigid support structure so as to distribute the compressive force and limit the deformation of said structure.
  • the rigid support structure is of cylindrical type surface, circular, elliptical, or polyhedral, for example substantially rectangular, depending on the shape of the excavation, or of the type surface of revolution, in particular of conical shape, or even in successive cylindro-revolutionary stacking. This allows him to better withstand the compressive forces exerted by the struts.
  • a plurality of rigid support structures are stacked on top of each other in depending on the depth of the excavation.
  • beams are inserted between struts and the wall of excavation.
  • the device can also include slabs against which support the struts, to adapt to the shape of the wall of the search, especially at the corners of the wall of the search.
  • the rigid support structure is fitted with support posts suitable for resting and / or entering the soil constituting the bottom of the excavation.
  • the rigid support structure also includes foundations adapted to penetrate the ground constituting the bottom of the excavation.
  • the foundations form a continuous structure of the same section or thickness as that of the rigid support structure.
  • the device presents, externally to the rigid support structure, additional means of foot buttressing of wall.
  • the device according to the invention has in particular good ability to be used in a seismic area.
  • Figure 1 shows, in top view, a search 1 of usual type dug at a certain depth in the ground of a ground on which is a construction site, for example a building.
  • This excavation 1 has any shape, for example of polyhedral section or circular, delimited by a rigid wall 2.
  • This wall can be molded in concrete, mortar or other, or be in the form of wooden planks or metal to support the earth from the soil dug to achieve said excavation 1.
  • a device 10 for shoring up this rigid retaining wall 2 is also shown in figure 1.
  • the shoring device 10 comprises a rigid support structure 12 disposed inside the excavation 1 and which for example has a circular section. All around this structure rigid support 12 are arranged stabilization pins 15 of the usual type which bear at one end 15a against the retaining wall 2 of the excavation 1 and, at an opposite end 15b, against the external wall 12a of said rigid support structure 12.
  • the struts 15 exert a force of centripetal compression on the rigid support structure 12 and they are distributed all around this structure 12 so that the compressive force is well distributed to avoid excessive deformation of one or more particular or sensitive areas of the rigid support structure 12.
  • the stabilization struts 15 are supported against beams 16 of stress distributions shown in the figure 2. These beams 16 are placed at the end 15a of the struts 15 and are arranged perpendicularly to said struts 15. They thus avoid the retaining wall 2 is damaged and for example marked by a possible insertion of the struts 15.
  • the struts 15 are supported against slabs 18, in particular in certain angles 2a, 2b, 2c and 2d of the wall of support 2 of the excavation 1.
  • the rigid support structure 12 rests on support posts 20 spaced apart and adapted to rest and / or penetrate the soil constituting the bottom of the excavation 1.
  • These support posts 20 are preferably sealed to penetrating sealing foundations 22 in the soil at the bottom of the excavation 1.
  • the foundations of sealing 22 can be in the form of a continuous ring substantially identical to that of the rigid support structure 12.
  • this ring 22 can also serve as a conventional compression ring in cooperating with additional means of buttressing 24, such as concrete, soil injections or cement or mortar injections under pressure (“jet grouting” in Anglo-Saxon terminology). ensuring more specifically a transfer of loads from the base of the wall 2.
  • the rigid support structure 12 is also removable and easy to remove once the operations have been carried out in the bottom of the excavation 1. It can be reused for other excavations and other sites which is particularly advantageous and economical.
  • the rigid support structure 12 also rests on a significantly fewer support posts 15 than in the prior art, without loss of efficiency.
  • Such a device 10 can be used regardless of the form of excavation 1, in particular thanks to the corner slabs 18. It finds an application particular in seismic zones because the range of the struts is clearly reduced, thereby reducing the effect of elastic deformation which can cause displacements of the retaining wall.
  • the rigid support structure can be constituted prefabricated elements of steel, reinforced or unreinforced concrete, or of materials composites which may be removable. It can also be performed in constrained concrete, reinforced or not. In this case, it is demolished at the end of works. Furthermore, the shape of the rigid support structure can vary in depending on that of the excavation.
