Definitions

  • the present invention relates to a new method for butting or laterally holding the vertical walls of deep excavations so as to allow earthworks without causing the destruction of these walls.
  • the vertical walls are butted or held in place during the excavation by performing, between different stages of the excavation, at least one floor which can thus withstand horizontal forces exerted by the ground outside the vertical walls.
  • the method according to the invention makes it possible to carry out the search in a simpler, faster and more economical manner.
  • the subject of the present invention is a method for abutting or maintaining the vertical retaining walls of deep excavations, characterized in that after having freely carried out the excavation to a depth compatible with the resistance of the retaining walls, it is carried out on the bottom from the excavation a ring slab which bears by its periphery against the vertical retaining walls and which rests on the bottom of the excavation; that after the solidification of this slab-ring it is joined to support it at the upper part of the retaining walls using guy lines; then continue the excavation from the inside of the ring slab to the lower end of the structure.
  • the ring slab which allows during the excavation to ensure the resumption of the horizontal forces exerted by the ground on the retaining walls, is used to form part of an intermediate floor.
  • Figure 1 a sectional view of a work being excavated in accordance with the invention.
  • the retaining walls 1 were made on the periphery of the structure before starting the excavation.
  • a ring slab 3 is then produced which rests on the bottom of the excavation and which bears by its periphery against the retaining walls 1, leaving in its center a large opening 4 as can be seen on the Figure 2 when the ring slab 3 has taken, it is connected by shrouds 5, preferably articulated at each of their ends, to the upper part of the retaining walls.
  • the lower ends of the shrouds 5 are subject to the ring slab 3 in the vicinity of the opening 4, but it goes without saying that the shrouds could be secured at different points of the ring slab 3 .
  • the ring slab 3 of which it remains only to close the central part according to a technique conventional thus serves as a floor element.
  • the method according to the invention allows a simple and economical way to carry out excavations in deep structures, and without it being necessary to carry out from the start of the excavation of deep support points to support the floor which is made first to support the horizontal forces exerted by the ground on the retaining walls, in order to allow the continuation of the excavation.
