Definitions

  • the present invention relates to a method for making watertight a hydraulic structure in compacted concrete or in embankments with a steep upstream slope (such as a ladder wall).
  • the body of compacted concrete dams may have excessive water permeability, especially at the level of the recoveries between successive layers. This permeability can lead, in the long run, to an attack of the cement constituting the concrete, especially in the presence of water of an aggressive nature.
  • the present invention therefore relates to a method for making watertight, inter alia, a hydraulic structure of compacted concrete such as a dam in which there is provided on the face of the structure in contact with water, an impermeable membrane which characterized in that said membrane is produced by staged series of plastic scales, welded together edge to edge, and anchored in the structure by vertical anchors allowing possible movement of the scales and initiating regular microcracks distributed in the structure.
  • the word "GEOSELLS” will be used to designate a set of worked and assembled materials, the word “tortoiseshell” being reserved for the upstream side only.
  • the edge-to-edge welds of the scales can advantageously be supplemented by thick joint covers, welded and arranged on the side of the structure.
  • the plastic GEOSELLS can be of any geometric shape, the rectangular shape being preferred.
  • these scales, of rectangular shape have a thickness of 1 to 50 mm, preferably 2 to 30 mm, a width of 2 to 8 m. , preferably 2 to 4 m, and a height of 1 to 6 m, preferably 1 to 2 m.
  • GEOSELLS can be made from any waterproof plastic. However, it is preferred to produce these from resins based on vinyl chloride and polyolefins.
  • vinyl chloride-based resins polymers and copolymers containing at least 50% by weight of monomeric units derived from vinyl chloride, polyvinyl chloride being preferred.
  • polyolefins polymers and copolymers containing at least 50% by weight of monomeric units derived from an olefin containing from 2 to 8 carbon atoms in its molecule, high density polyethylene being preferred. It is understood that the material constituting the GEOSELLS can contain usual additives such as stabilizers and in particular anti-UV agents and reinforcing agents.
  • each collector comes out individually in the collection gallery, which makes it possible to precisely locate any defective zone.
  • this drainage is also ensured by interposing a geotextile between the structure and the membrane.
  • this geotextile coats the vertical anchors of the scales which will be described later, it is included in the expression "GEOSELL”.
  • the geotextile is fixed locally on the membrane during the implementation; it separates the scales and the anchors, after backfilling, from the mass to be sealed, and it allows the drains to be saved during possible injection by use in double thickness.
  • the vertical anchoring of the scales is carried out so as to leave the impermeable membrane a possibility of vertical displacement and to induce microcracks in the surface region of the structure in order to avoid the need to provide expansion joints by sawing in the structure. of compacted concrete.
  • the vertical anchoring of the scales is carried out at intervals, for example, from 1 to 2 m and so as to ensure, at the same time, the formation of vertical drainage collectors.
  • the vertical anchoring is ensured by means of plates welded orthogonally and vertically on the face of the scales facing the structure, said plates being inserted into the structure, a drainage pipe. being provided at the level of the plates (plastic tube cut in half longitudinally and fixed to the plate, perforated cylindrical profile welded to the plate, etc.).
  • the plates extend over the entire height of the scales and the vertical anchors of the superimposed scales are made in such a way that the pipes constitute vertical collectors for continuous drainage.
  • This embodiment also has the advantage of promoting the initiation of the desired microcracking in a uniformly distributed manner.
  • tubular profiles can advantageously be equipped with a profile with a cutting edge on their generatrix opposite the orthogonal bands so as to promote microcracking, this blade also entering the name "GEOSELL”.
  • the width of the plates is generally from 100 to 500 mm and preferably from 200 to 400 mm.
  • the constituent elements of the vertical anchors are preferably made of a material identical to that constituting the scales, so as to favor their prior positioning on the scales, for example by welding.
  • the geotextile interposed between the scales and the structure must surround the vertical anchors and this, according to a thickness and an identical system (geotextile complex) in order to avoid, at compression due to upstream water or impacts, any risk of concentration. constraints.
  • the scales constituting the membrane are preferably also held in place by horizontal anchors constituted by at least one tab welded horizontally opposite the structure and forming an integral part of the GEOSELL, said tab being sealed in the structure works in shearing so as to regain the weight of the GEOSELLS.
  • the legs are placed away from the anchoring tube, which can then serve as stiffening reinforcement for the GEOSELL.
  • the face of the GEOSELLS in contact with water can advantageously be protected by a layer of resin concrete (30 to 60 mm thick) so as in particular to reinforce their resistance to impacts which may be, for example, caused by bodies floating.
  • a layer of resin concrete (30 to 60 mm thick) so as in particular to reinforce their resistance to impacts which may be, for example, caused by bodies floating.
  • the constituent material for example with high density polyethylene
  • pebbles or tiles or even wood are laid hot (followed by cooling), which promotes local melting of the support. , hence a partial incorporation.
  • Such integrated protection is part of the GEOSELL and completes it in aesthetic value as well as protection against ultraviolet rays (UV).
  • the GEOSELLS are put in place as the structure stretches and can advantageously serve as lost formwork.
  • the GEOSELLS are arranged as climbing formwork-type supports, anchored in the structure through the lower GEOSELLS already in place, with the help of expansion tools called here "GEOTOOLS".
  • GEOTOOLS expansion tools
  • the structure 1 of compacted concrete is coated on its face in contact with water with an impermeable membrane 2 constituted by series of GEOSELLS in plastic material with the interposition of a geotextile 4.
  • the GEOSELLS are fixed to each other by continuous welds 5 on thick joint covers 6, welded in the workshop either by penetrating heating tip 7, or by high frequency welding heating an inclusion metallic or PVC 8.
  • the horizontal anchoring of the GEOSELLS is carried out by the stiffening tabs 10 placed at the head of the cheeks 11 equipped with the anchoring holes 12 and securing the tube 13 with the membrane 2.
  • a cuff tube for possible injections can be placed at 14 and benefit from a double thickness protective bonding 15 of the geotextile complex 4.
  • the vertical anchoring of the GEOSELLS 3 is ensured by tubular sections 13 ensuring drainage and fixed vertically on the scales 2 by strips 11 orthogonal to the scales 2.
  • the fastenings between the scales 2, the strips 11 and the tubular sections 13 are provided by welding.
  • the tubular sections 13 and the strips 11 are inserted into the structure 1 when it is put in place.
  • the geotextile 4 completely surrounds the vertical anchors so as to ensure a partial separation between the structure 1 and the membrane formed by the scales 2.
  • Profiles with a sharp edge 16 are fixed by clipping onto the ends of the vertical anchors surrounded by the geotextile 4. During the installation of successive GEOSELLS, it is also advisable to ensure the alignment of the tubular profiles 13 between the superimposed GEOSELLS so as to constitute vertical drainage collectors.
  • the alignment of the tubular sections 13 is carried out at the same time as the installation of successive GEOSELLS since the GEOTOOL tool 20 illustrated in FIG. 5 allows centering of continuity at the same time as the blocking in the lower part already in place.
  • These actions are carried out from the tubular body 17 and the expansion shoe 18 allowing the centering on the recovery and anchoring of the order of 1 m inside the structure 1 in place.
  • the expansion is carried out by half-turn of an axis carrying two cams 19, a return spring system 23 allows the tool to be removed after stabilization of the embankment making GEOSELL captive. Drainage slots 21 are produced by sawing and have a capacity calculated as a function of the immense capacities of the tube 13.
  • GEOTOOL 20 In the upper part of the GEOTOOL 20, a system of two screws 22 allows the adjustment of the new GEOSELL set up.
  • the holes 12 left in the cheeks 11 allow, in addition to handling or various hooking, to achieve using plastic tubes easy anchors for grids called "GEOGRILLES", when using embankments reinforced by GEOGRILLES.
  • GEOGRILLES easy anchors for grids called "GEOGRILLES”
  • the use of GEOGRILLES for any backfill can be imposed on the surface to avoid any crack initiation.
