Definitions

  • the invention relates to plugging and sealing of cracks or areas permeable to liquids present in walls of masonry structures, or in reinforced concrete, submerged or buried. It relates more particularly to a device for sealing, sealing, consolidating and restructuring said cracks or permeable areas, as well as a sealing process using the above-mentioned device. It is defined in the claims.
  • masonry or reinforced concrete structures such as basements of buildings, garages or underground shelters, tanks, tanks or tunnels for example, are buried in soils with permanent or temporary water concentrations sometimes important. Such situations are frequent in the immediate vicinity of lakes, streams or groundwater. In other cases, such structures can be immersed in a lake or a watercourse, for example. As a result, the external surface of the walls of such structures can be in direct contact with an environment that is at least highly humid, or even aqueous.
  • the device comprises a cover plate 1 for the crack or the area permeable to liquids.
  • Said plate 1 is a mechanically resistant plate, flat or curved as the case may be. It may for example be a metal plate such as a steel sheet several millimeters thick, said sheet being able to be smooth or ribbed and thus to see its reinforced rigidity.
  • the surface of the plate 1 will of course be calculated so as to cover the entire oozing area identified on the wall; if necessary, the technician may avail use a whole series of plates of various shapes and sizes.
  • the shape of the plate 1 will be such that it can absorb the movements of expansion of the joint separating said plates ' (Fig. 4 ).
  • the device comprises means making it possible to fix the plate 1 to the masonry or concrete wall.
  • the usual usual technical means are used for such purposes: nails, screws, bolts or other means of anchoring in cement or concrete, passing through corresponding holes 9, arranged in the peripheral zone of the plate 1.
  • fastening means can be reinforced by props taking, for example, support on the wall opposite to that being treated.
  • the device further comprises means 3 ensuring the tightness of the contact of the plate 1 with the wall.
  • Such means may advantageously consist of a seal 5 disposed on the periphery, or in the vicinity of said periphery, of the face 6 of the plate 1 in contact with the wall.
  • Said seal 5 will preferably be arranged so as to cover the area reserved by means of fixing 2.
  • the nails or bolts used will be embedded in the mass of said seal 5.
  • the seal 5 will preferably be made of an elastic material , resistant to corrosion both of water and of chemical agents such as organic solvents for example.
  • it is possible to use elastic polymerized materials making it possible to adhere metal to concrete, such as polybutadiene, polypropylene, poylurethane, for example.
  • seal 5 made of a polymerizable material such as a slow polymerization sealant: the composition of such a sealant will then be formulated in such a way that the polymerization is not completed until the device has been put in place. and attached to the wall.
  • the device comprises means 4 for bringing an injectable liquid composition 8 into contact with the wall surface thus covered.
  • means 4 it is advantageously possible to use any suitable conventional means, such as an injection pump connected to the plate 1 by means of at least one end piece-7, a threaded end piece for example, integral with the plate 1.
  • the sealing, sealing, consolidation and restructuring of the cracks or permeable zones detected in the following manner is carried out.
  • a device according to the invention is chosen, the surface of the plate 1 of which is such that it completely covers, preferably exceeds, said crack or said area.
  • a seal 5 around the periphery of the face 6 of the plate 1 selected then said plate is applied to the wall, at the location identified.
  • the plate 1 is then fixed using suitable means 2, such as nails projected by a pneumatic gun for example.
  • suitable means 2 such as nails projected by a pneumatic gun for example.
  • the plate 1 thus arranged can be temporarily left as it is, then acting as a drain: this will give us the possibility of determining the flow rate of the leak detected and thus of predicting the pressure with which the liquid composition 8 will have to be subsequently injected to discharge the seepage liquid outside the wall.
  • the appropriate liquid composition 8 is injected.
  • the injection is carried out at a pressure calculated in such a way that the oozing liquid is gradually discharged outside the wall, in sufficient quantity to seal the entire crack or the permeable zone treated, thus leading to its consolidation. and its restructuring.
  • the device can be removed from the wall, thus revealing the crack or the clogged area. If necessary, the means 4 of the device can be simply disconnected from the plate 1, the nozzle 7 then being provided with an adequate sealing means, and the assembly left fixed to the wall.
  • a liquid composition is used, at least part of which is transformed, at ambient temperature, into an impermeable solid mass.
  • a commercial polymerizable liquid is used, such as a hardenable resin with high capillary penetration, based on polyester, polyurethane for example, or a two-component epoxy type resin.
  • a liquid generating a foam on contact with the humidity of the ambient medium to give for example a foam based on polyurethane.
  • a person skilled in the art will himself select, from the known products at his disposal, the most suitable liquid composition 8.
