Definitions

  • the present invention relates to a production method and a formwork for an end joint of a wall panel molded into the ground, and more particularly to such a method in which a trench is dug, a formwork is placed at its end, concretes the trench and extracts the formwork.
  • the trench is generally dug under bentonite mud.
  • a formwork is immersed in the mud which is placed at the end of the trench. Concrete is then poured to replace the mud, the concrete therefore coming into contact with the formwork.
  • a new trench is dug adjacent to the first on the other side of the formwork, generally using it to guide the perforating machine.
  • the present invention aims to overcome these drawbacks.
  • the invention firstly relates to a process for producing an end joint of a wall panel molded in the ground in which a trench is dug, a formwork is placed at its end, and concrete is placed. the trench, and the formwork is extracted, characterized in that prior to concreting the trench, the face of the formwork is coated on the concrete side with a thin material capable of being abandoned in the trench, and that the formwork substantially vertically.
  • a sheet material capable of being folded is used as the thin material, and this sheet is kept on the formwork by folding its edges over the edges of the formwork.
  • a sheet of magnetic material is used as the thin material, and this sheet is held on the formwork using electromagnets.
  • a sheet of relatively airtight material is used as the thin material, and this sheet is held on the formwork using suction cups.
  • a sheet material is used as the thin material, and this sheet is fixed to the formwork using means of low mechanical resistance, such as welding spots or dowels, likely to break during extraction of the formwork.
  • the invention also relates to an end formwork for the implementation of the method as described above, characterized in that it comprises, on its face concrete side, a thin coating capable of being abandoned in the trench.
  • this formwork comprises, for the maintenance of said coating, electromagnets or suction cups.
  • the covering is fixed to the formwork using means of low mechanical resistance.
  • a formwork comprising a groove in which an inflatable seal is engaged, the coating then being held on the formwork at least partially by its wedging in said groove using said inflatable seal.
  • the method according to the invention comprises the known steps consisting in digging a trench 1 in the ground, most often under bentonite mud, in placing at the end of this trench a formwork 2a, 2b, 2c, for example provided with a seal 3 of the so-called "water-stop" type, for concreting the trench 1, for digging a second 1 ⁇ trench on the other side of the trench 1, and for extracting the formwork.
  • the extraction of the formwork had to be carried out, either before the concrete of the trench 1 had completely set in order to avoid too great adhesion, but this imposed a delay very short between the concreting of the trench 1 and the extraction of the formwork, or to have means allowing a lateral displacement of the formwork towards the trench 1 ⁇ in order to ensure its detachment from the concrete of the trench 1.
  • the forms 2a, 2b and 2c comprise a sole 4 on which are fixed two watertight boxes 5 delimiting between them a longitudinal groove 6.
  • the seals 3 comprise an inflatable core 7 supporting two wings side 8 (figure 1). One of the lateral wings 8 is engaged in the groove 6, as well as at least partially the core 7. The seal 3 is held between the two boxes 5 by inflation of the core 7.
  • the face of the formwork facing the concrete side of the trench 1 is coated with thin sheets 9a, 9b, 9c, capable of being abandoned in the trench during the extraction of the formwork.
  • the sheets 9a are made of magnetic material, for example galvanized steel, and are held on the formwork during the positioning of the latter by electromagnets 10.
  • the sheets 9b are made of a relatively airtight material such as metal or a synthetic material, and are held on the formwork 2b by suction cups 11.
  • the suction cups 11 are arranged in holes formed in the walls of the boxes 5, and include a support grid 12 preventing the puncture of the sheets 9b, and an O-ring seal 13 at the periphery of this grid. Means, not shown, make it possible to create a vacuum in the boxes 5 so as to press the sheets 9b against the external walls of the formwork.
  • the sheets 9c are made of a material capable of being folded, and are fixed to the formwork 2c by folding their edges 14 around the lateral edge of the sole 4, and their edges 15 inside the groove 6 where they are blocked due to the inflation of the core of the seal 3.
