Definitions

  • the invention relates to a procedure for making a liquid-tight wall in the ground, according to which procedure a trench is made in the ground, the trench is filled with cement, at least a length of sealing foil and at least an auxiliary construction for holding one side of the length in the trench are let down vertically and the auxiliary construction is later removed again from the trench.
  • a procedure of this type is known from EP-A-0 292 765. According to the procedure described in this patent application lengths of a plastic foil are placed one next to the other in a trench filled with bentonite. The vertically overlapping edges of these lengths are held in an auxiliary construction which is pumped out after placing the lengths. In the pumped out hollow auxiliary construction a welding apparatus is then introduced and with this the overlapping edges are welded to each other. Through the necessity of pumping out the auxiliary construction and welding the edges to each other this known procedure is relatively laborious.
  • the purpose of the invention is to remedy these disadvantages and to provide a procedure for making a liquid-tight wall in the ground which is very simple and can also be easily utilized for great depths of the wall.
  • a first trench of a wall part, called panel is dug and this is filled with cement
  • two auxiliary constructions are installed in this first trench, one at each extremity of the trench, with a slot provided with a seal over their height and on their sides facing each other and a length of sealing foil is lowered between these auxiliary constructions and a joining construction down on both edges thereof so that the length is connected by its edges to the auxiliary construction
  • a joining part of the joining construction is present and the slots in the sides of the auxiliary constructions are sealed
  • a second trench for a second panel is dug at a distance which is almost equal to the width of the length of sealing foil and this trench is filled with cement
  • two auxiliary constructions are installed therein in the manner described above with a length of sealing foil between them which is connected to these auxiliary constructions by auxiliary constructions of which a joining part extends into the auxiliary constructions, subsequently an intermediate trench, which is filled with cement, is dug between the two trenches and thus between two auxiliary constructions,
  • the joining construction of the lengths in a first and a second trench is a separate joining element in relation to the length, which joining element is installed with a joining part in an auxiliary construction and has a joining edge on its opposite edge which works together with a joining edge on an edge of the length.
  • the joining edge of a length of sealing foil can be formed by a folded over edge which forms a sleeve and a relatively stiff tube which is installed in this sleeve.
  • a rollable foil is utilized which is unwound from a drum in the trench, which foil is provided with weights.
  • the invention also relates to a wall manufactured according to one of the preceding embodiments.
  • a first trench 3 with a length of 3 to 8 meters and a width of 0.3 to 1.2 meters is dug with a trencher or trench excavator. During or immediately after the digging the trench 3 is filled with bentonite 4 or a mixture of bentonite and cement. The condition as represented in figure 1 is obtained.
  • This auxiliary construction 5 can consists of one element with a length of 12 to 16 meters or, if the trench 3 is deeper consist of several elements placed above each other, as represented in figures 14 and 15.
  • each auxiliary construction 5 contains a hollow tubular base 6 to which protruding sleeves 7 connect on one side between which a slot 8 is formed.
  • Two compressed air hoses 10, which form seals, are glued in semicircular notches 9 in the two sleeves 7 on the extremity of the slot 8.
  • the width of the base 6 is of course equal to the width of the trench 3.
  • the two auxiliary constructions 5 are so placed in the trench 3 that the slots 8 are directed with their open extremity toward each other. If the auxiliary construction 5 consists of several elements not only the base 6 and the sleeve 7 of the elements located above each other are connected to each other but also the compressed air hoses 10 of these elements.
  • each auxiliary construction 5 which, as especially appears from figures 9 and 10 consists of a stiff metal strip 12 with a gutter-shaped joining element with C-shaped cross-section 13 respectively 14 on both edges.
  • the two joining elements 13 and 14 consist of round tubes which are cut open on the side away from the strip 12.
  • One of the joining elements 13 extends into the slot 8 of the auxiliary construction 5.
  • the compressed air hoses 10 of the auxiliary construction 5 are inflated so that not only the slot 8 is sealed but also the joining construction 11 is fixed to the auxiliary construction 5.
  • a length 15 of a supple foil of plastic such as polyethylene with high density starts to be lowered.
  • the foil is unwound from a drum 16 mounted on a vehicle 17.
  • elements 18 of metal or concrete are weighted with elements 18 of metal or concrete.
  • the two edges of the length 15 are folded over and so attached to each other by means of sewing, gluing or fusing together, that a sleeve 19 is formed into which a perforated tube 20 is slid.
  • This tube 20 is made of plastic, relatively stiff but still supple enough to be able to be wound up on the drum 16.
  • the diameter of the perforated tube 20 is smaller than the inside diameter of the joining elements 13 and 14.
  • the length 15 has such a width that the two sleeves 19 with a perforated tube 20 therein formed on their edges can slide into the joining elements 14 located outside the two joining constructions 11 as is represented in detail in figure 12.
  • the tube 20 sits with some play in the joining element 14 but cannot get out of this joining element sideways because its diameter is greater than the slot in the joining element.
  • the foil is cut off above the ground and the upper extremity of the length 15 rests on the bottom.
  • the vehicle 17 with the drum 16 can now be removed.
  • the joining connection is further finished by injecting a swelling and stiffening liquid 21 such as a polyurethane mixture into the perforated tube 20.
  • a swelling and stiffening liquid 21 such as a polyurethane mixture
  • This liquid fills the entire inner space of the sleeve 19 through the perforations of the tube 20 and with that, especially during the swelling, presses the sleeve 19 against the internal wall of the joining element 14 as represented in figure 13.
  • the connection between the length 15 and the joining construction 11 is watertight.
  • the length 15 was installed in a mixture of bentonite and cement, then this mixture is allowed to harden or stiffen and then the first panel 22 is ready. If the slot 3 was only filled with bentonite 4 or a tixotropic liquid, then after the installation of the length 15 this liquid is replaced by another cement 23 which hardens or stiffens. After the hardening or stiffening the first panel 22 and the condition represented in figure 2 is obtained.
  • a second panels 22 is made at a distance from the first panel 22 that is somewhat smaller than the width of a length 15.
  • the manufacture of the second panel 22 is therefore also started with the digging of a trench 3 as represented in figure 3.
  • 2 auxiliary constructions 5 are installed in this trench each of which is provided with a joining construction 11.
  • a length 15 of foil is installed between the joining constructions 11 after which either the original cement is allowed to harden or stiffen in the trench 3 if this was hardenable or stiffenable, or this original cement is replaced by new cement 23 which is hardenable or stiffenable which is then allowed to harden or stiffen.
  • the condition represented in figure 4 with two completely formed panels 22 is obtained.
  • a third trench 24 is dug out between the two formed panels 22 and in fact between the two neighboring auxiliary constructions 5 of these panels as represented in figure 5.
  • This intermediate trench 24 is immediately filled with bentonite 4.
  • the intermediate panel 25 of the wall 1 is now formed in this intermediate trench as follows.
  • a length 15 is installed with edges formed by the sleeves 19 in which sits a perforated tube 20, in the joining elements 13 of the two aforementioned joining constructions.
  • a dilatable and stiffenable liquid 21 such as a polyurethane mixture
  • an intermediate panel 25 is obtained as represented in figure 7 and therefore a uninterrupted wall 1 in which a seal is continuously present, namely a seal formed by three lengths 15 and joining constructions 11 situated between the lengths.
  • this wall can now further constructed as desired whereby therefore each time a following panel 22 is made in the above mentioned manner at a distance from the last panel and thereafter an intermediate panel 25 is made between these two panels 22.
  • a length 15 of plastic foil is not used but a length of a metal foil.
  • the metal foil must be sufficiently pliable in order to be able to be rolled up.
  • the edges of the length are then not formed by sleeves but just folded over edges of the metal foil. Because these edges have sufficiently stiffness the perforated tube 20 can be omitted.
  • an additional non-perforated supple tube is installed in the perforated tube 20 which at the bottom ends under the tube 20.
  • bentonite is pumped through this additional tube which blows clean the inside of the corresponding joining element 13 or 14 in which the sleeve 19 is installed and thereby facilitates the lowering.
  • this additional tube is withdrawn from the ground under simultaneous injection of the swelling liquid 21 which fills the perforated tube 20 and fills the corresponding sleeve 19 through the perforations.
  • the procedure can be applied with relatively light cranes.
  • the procedure can be utilized to any depth and on the spot welding is not necessary.
  • the lengths 15 of foil can be taken relatively wide so that the number of connections between the lengths can be limited to a minimum.
  • the foil utilized for the length 15 is relatively inexpensive and, once it is in the ground in a hard or stiffened cement this foil is protected for ever and it can fulfill its watertight function.
  • the procedure is very fast and inexpensive.
