Definitions

  • the present invention relates to a method for producing a basement under an existing construction.
  • the object of the present invention is to propose a method of producing a basement under an existing construction which uses prefabricated elements, these being put in place without using handling equipment.
  • the method according to the invention is characterized in that the prefabricated element or elements present by themselves or are provided by temporary addition of elements of positive buoyancy, in that a dig is excavated extending to the exterior of the construction and under it, including at least the space provided for the prefabricated element entering into the construction of the basement, the volume of this excavation outside the construction having a volume such that 'it can accommodate the prefabricated element and the section of the connecting part between the external part of the excavation and the location of the prefabricated element allowing the passage of this element; in that one optionally seals this excavation and puts it in water to a level sufficient to float the prefabricated element lowered into the external part of the excavation; brings the prefabricated element in the floating state of the external part of the excavation to its location under the construction and adjusts its level by modifying its buoyancy level.
  • the prefabricated element can be constituted by a monolithic box forming the entire basement to be produced.
  • the prefabricated elements can be constituted by boxes corresponding to said parts or to said parts. When the elements in the box have openings, these can be obstructed by temporary cladding and the element is waterproof with water by a plastic wrap sheet.
  • the prefabricated elements constitute elements of hollow load-bearing walls.
  • These load-bearing wall elements which may constitute formwork elements are preferably constituted by two parallel concrete walls joined by reinforcements forming beams and a base plate.
  • the end sealing of the formwork elements can be ensured by a concrete veil but it is preferable, to ensure the subsequent overall connection of all the wall elements during filling, to use a removable wall with possibly a peripheral wrapping of the element by a plastic sheet.
  • the element level can be adjusted by modifying the water level in the excavation or by modifying the element's own buoyancy by inserting it or removing a ballast such as sand or some water.
  • the level adjustment can be used, either to lower the element on a sole cast in advance or on temporary wedges awaiting pouring of the sole or the raft, or to support the prefabricated elements under the beams of the floor of the existing construction, either directly or through beams and / or slabs. Due to the difficulty encountered in performing the immersion setting of the prefabricated elements, it is preferable to lower them in abutment on support elements made beforehand on the excavation bottom and to secure beams or slabs on their top which can be brought into position and supported under the floor of the existing construction by floats.
  • lateral stabilizing floats which allow, by adjustment of their own buoyancy and / or that of the element, of tilting the element to adjust its verticality or to ensure a reduction in its draft and / or its air draft, for example for the '' introduce into the excavation in the basement from an external excavation of reduced depth by passing under a recovery beam in the underground.
  • the reference 1 generally designates the existing construction
  • the reference 2 the walls of the excavation covered by a sheet of impermeable plastic
  • 3 the water poured into the excavation.
  • Reference 4 designates the opening made in the base of the construction with a beam 5 of load recovery, to put in communication the outer part 6 of the excavation with the part 7 located under the construction.
  • the basement consists of a one-piece box 8 which is placed under the construction.
  • This box is made in a reinforced concrete workshop using the traditional formwork concrete technique.
  • This box must however, in the context of the method of the invention, be able to be floated, that is to say that its weight must be less than the weight of the volume of water that it can move to its sealing level.
  • the dimensions of the box must allow the transport of the box by road in ordinary or exceptional convoy, the height alone remaining constant and between 2.20 and 2.50 meters.
  • the dimensions and weight of the box must allow it to be handled using a crane available on site. Failing this, it is possible to provide part 6 of the excavation with an inclined plane to allow the descent of the box into the excavation. If necessary the basement can be subdivided into several elementary caissons which will be joined in part 7 of the excavation. Slinging points 9 are provided for construction on the box, some 9a for handling, others 9b for pushing the box under construction.
  • the parts 6 and 7 of the excavation have, in this embodiment, each of the dimensions greater than the dimensions of the box 8.
  • the latter is lowered into the external part 6 of the excavation and is poured into the latter of water 3 until the box floats.
  • the bottom of the excavation is leveled and adjusted with sand so that the height between the bottom of the excavation and the underside of the floor 10 or the lower wing of the beam 2 is not only slightly greater than the overall height of the box.
  • the horizontality of the box 8 is perfectly adjusted, for example by ballasts such as sand, and its level is adjusted by modifying the water level 3 so that it is barely lifted from the bottom of the excavation.
  • the finishing works include the recovery of the underlayment of the floor 10, for example by injection of concrete between a formwork bearing on the box and the underside of the existing floor, the recovery of the front wall on the basement wall, the installation of an internal staircase hopper and the installation of the staircase 13.
  • the wall of the box which comes in front can be constituted by a sheet pile wall with waterproofing by a plastic sheet wrapping the lower part of the box, said wall being removed after installation and part 6 of the excavation being arranged downhill. Otherwise part 6 is filled.
  • each element consists of two plates 15 for example 5 cm thick joined at their bases by a sole 16.
  • the element can be made of reinforced concrete with a trellis 17 ensuring the spacing of the plates.
  • the spacing between the opposite faces of the plates 15 is at least 17cm, which gives a draft of approximately 2m20.
  • the sealing of the end faces can be ensured by a concrete veil or by a removable board and the element can be wrapped in a waterproof plastic sheet 18.
  • the construction of the basement is preferably carried out in several phases to reduce the duration of non-shoring.
  • Figures 9 and 10 illustrate an implementation in two phases, but the site can be subdivided into a larger number of phases if the nature of the land requires it.
  • An external excavation 6a is carried out which is greater than the dimensions of an element and a first part 7a of the excavation is excavated underground, under construction, the walls of the excavation are covered with a waterproof sheet 2 which has a sufficient surface. to fill the entire excavation, the excess surface being stored in-2a. Is poured at the location of the walls a sole 19 which will adjust the final position of the elements.
  • the excavation 6a-7a is then filled with water and a first element 14 is floated in the part 6a which is pushed and guided in place then lowered onto the sole 19 by slightly lowering the level of the water in the excavation or by ballasting it for example by pouring a small volume of concrete.
  • Hauling and guiding the element in place can be done in many ways. To avoid having to work under a reduced air draft, one can anchor in the walls of the excavation or under the floor of the pitons with return pulleys 20 over which pass traction cables 21 which are pulled from the outside. End of travel shims 22 can also be provided to ensure the automatic adjustment of the element on the sole 19. The element floating freely the forces necessary for movement are obviously very low.
  • the excavation can be drained and props 23 placed between the elements facing each other to provide shoring.
  • the excavation 7 is then completed, the sheet reserve 2a deployed to garnish the surface of the excavation and the establishment of the other elements is continued in the same manner.
  • Finishing the sub - soil can be carried out as in the case of a box, the tamping sand 12 is more easily carried out between the sheet 2 and the elements 14 by injecting the sand from the excavation 6a and the carrying by a current of water created by pumping at a point opposite the excavation.
  • the recovery of the construction floor under construction can be carried out by pressing on the upper edges of the elements 14 of the flat beams 24 (FIG. 7) which may have support wings 25 and by injecting concrete between these beams forming formwork and the construction floor.
  • These beams can be put in place using usual handling means circulating in the dry basement but it is possible, as illustrated in Figure 11, to use.
  • a float 26 which carries, by props 27, the beam 24.
  • the beam 24 can be slid between the floor 1 and the ridge of the elements 14.
  • This method of installation can prove to be particularly interesting in the case where an opening remains at the right of the excavation 6a. It is possible by playing on the buoyancy of the float 26 or on the level of the water in the basement to pressurize the beam 24 against the floor to take up the loads and to perform the wedging between the wings 25 and the upper surface of walls cast in elements 14.
  • the element 14 is associated with a fitting 28, a float 29 which has two chambers, l 'a lower 30 filled with air and the other upper 31 which can be ballasted.
  • the whole float element is then subjected to a system of forces which essentially comprises the weight P of the element, the buoyancy of Archimedes F of the submerged part of the element, the buoyancy of Archimedes f of the submerged part of the float 29 and the weight p of the ballast, in practice of the water which is in the compartment 31.
  • F + f P + p and the equality of the couples ensured on the whole by the four forces .
