Definitions

  • the invention relates to a diaphragm wall for the vertical sealing of liquid-bearing and / or gas-bearing layers, in particular for sealing contaminated layers of earth, a slot being introduced into the soil up to an impermeable horizontal layer, which is filled with a mass such as bentonite and a seal is sunk therein , which is composed of several sheets, which are connected to each other at the joints by a lock consisting of two interlocking profiles, one of which has a barbed tip.
  • Such diaphragm walls are used above all in the sealing of landfills or in the sealing of liquid-holding containers or liquid-carrying lines or channels.
  • the prerequisite is usually that there is a natural barrier layer below the area to be sealed laterally.
  • Clay layers often occur as natural barrier layers.
  • the diaphragm walls are then excavated to the side of the area to be sealed down to the clay layer underneath and at the same time filled with thixotropic mass. Bentonite is preferably used as the thixotropic mass. Bentonite itself forms a certain seal. In order to achieve a clear seal, however, either an extremely thick bentonite layer is required or the thin layer consisting of bentonite must be provided with an additional seal.
  • the waterproofing membranes have a width between 1 m and 2.5 m. Even if even larger sheets can be produced, the question arises of connecting the individual sealing sheets together to form a longer seal for a diaphragm wall.
  • the common connection technology is a welding process. A sealing membrane created in this way is difficult to handle if it exceeds a certain length. That is why there are connections at intervals of 1 to 3 m provided with a lock.
  • Such locks are formed by interlocking profiles.
  • the profiles can be molded or welded on.
  • the interlocking profiles form a kind of tongue and groove.
  • the seal between the interlocking profiles is formed purely mechanically, ie by choosing a suitable socket, the interlocking profiles are so tight that hardly any liquid can penetrate between these profiles.
  • the invention is therefore based on the object of improving the seal in the known lock.
  • the sealing effect increases according to the number of tips arranged side by side.
  • the tips arranged next to one another are preferably of identical design. It is also advantageous to give the two corresponding profiles the same tips. Then there are two peaks arranged next to one another on the one profile, while the corresponding profile has a central peak and two half peaks arranged next to it.
  • the profile provided with the middle tip has a channel extending in the longitudinal direction through the profile for pressing sealing means.
  • Fig. 1 shows two profiles that are welded to a material web 1 or 2 with the corresponding butt ends of the sealing sheets to be connected.
  • the profiles are made of a suitable material.
  • the material web 1 has a tip 3 with barbs 4 at the front.
  • the tip 3 and barbs 4 are rounded.
  • the tip 3 engages in a profile 5 which is provided with a recess extending in the longitudinal direction of the profile such that the tip 3 can be inserted into this recess.
  • a gap 7 is formed between the base 6 of the recess and the tip 3.
  • the gap 7 is provided for pressing with a sealant. After the sealing sheets have been introduced into the slot wall filled with bentonite, the sealant is pressed from above through a channel 8 into the profile 5. The channel 8 is closed at the bottom and connected to the gap 7 via an opening shown in dashed lines. The sealant is pressed in until it emerges at the top.
  • a hardening synthetic resin is optionally used as a sealant.
  • the rounding off of the barbs 4 leads to an advantageous sealing, in that the barbs 4 close in the corresponding recesses in the profile 5.
  • the sealant with the pressure given to it during compression, secures the barbs 4 against the profile 5 or in the associated recesses in the profile 5.
  • FIG. 2 shows a profile with a central tip 10 and two half tips 11 arranged next to it.
  • the tips 10 and 11 leave recesses 12 between them which show the cross section of the corresponding profile.
  • the corresponding profile therefore has two tips with which it is pushed between the tips 10 and 11. All tips are the same in cross-section with the difference that the tips 11 are only would complement one another by putting them together.
  • the profile according to FIG. 2 as well as that according to FIG. 1 is produced by pressing or extruding. In the manufacture of the tool for pressing or extruding, the tips with the barbs are designed somewhat larger than the corresponding designs according to the invention. This ensures that the profiles are pushed together.
  • FIG. 2 also has a channel for pressing sealants. This is designated in FIG. 2 with 13 and connected to the recesses 12 via openings shown in dashed lines.
