Definitions

  • the invention relates to a subsurface seal, in particular excavation protection, from a slot-sealing wall guided into the hydraulically required depth and a sealing sole made of high-pressure injection bodies connected to its foot.
  • the invention has for its object to perform a background seal of the type mentioned economical, but so that it nevertheless satisfies all the desired requirements.
  • the achievement of this object is that the Dichtwandfuß is executed in concrete and / or steel and the slot sealing wall above its foot consists of a sealing material with respect to the strength of the Dichtwandfußes reduced strength.
  • the sealing wall foot has one for a sufficient load absorption, i. for the connection or the jetting of the high-pressure injection body designed strength, while the overlying slot sealing wall can be made of much cheaper material. As a result, the object of the invention is achieved.
  • the sealing wall foot consists of precast concrete elements, steel components and / or contractor concrete. In any case, it is sufficient in most cases, run the slot sealing wall above her foot with a designed only for the absorption of water pressure differences strength. Where the underground seal is also intended to serve as Baugrubensch or for other reasons higher horizontal loads are to be incorporated according to a preferred embodiment in the slot sealing wall to the static required depth-bearing elements in particular be built from sheet piling and / or Steckarribauriin.
  • the sealing sole itself is constructed of overlapping primary bodies or advantageously of primary bodies and the inhomogeneities of the primary bodies eliminating secondary bodies.
  • the background protection shown in the figures serves as a construction pit protection. It consists of a guided in the hydraulically required depth slot sealing wall 1 and connected to the foot 2 sealant 3 from Hochdruckinjetechnischstechnischn. 4
  • the sealing wall 2 consists of precast concrete elements and has a designed for a sufficient load bearing strength.
  • the Dichtwandfuß 2 but could also be executed in Kon Consumerorbeton.
  • the slot sealing wall 1 consists of a sealing material with a relation to the strength of the sealing wall foot 2 reduced, designed only for the absorption of water pressure differences strength.
  • Fig. 1 it is indicated that the sealing sole 3 is composed of primary and secondary bodies 7, 8.
