Definitions
- the invention relates to a sub-surface seal, in particular Excavation, from one to the hydraulically required Deep led diaphragm wall and one their foot connected sealing sole made of high-pressure injection bodies.
- the invention has for its object a sub-surface seal of the type mentioned in the introduction more economically, but so that it can meet all the desired requirements enough.
- the solution to this problem according to the invention consists in that the sealing wall base is made of concrete and / or steel is and the diaphragm sealing wall above your foot from one Sealing material with a compared to the strength of the sealing wall base reduced strength.
- sealing wall base according to a preferred embodiment of prefabricated concrete parts, Steel components and / or contractor concrete. In any case, it is sufficient to have the slotted sealing wall above of her foot with just one for taking Water pressure differences designed strength to perform. Where the sub-surface waterproofing also serves as construction pit protection should serve or for other reasons higher horizontal loads can be recorded according to a preferred embodiment into the diaphragm wall up to the statically required Depth bearing elements in particular Sheet piling and / or plug-in support elements installed his.
- the sealing base itself is made of overlapping primary bodies or advantageously from primary and the Inhomogeneities of the secondary bodies eliminating primary bodies built up.
- the subsurface protection shown in the figures serves as construction pit protection. It consists of one in the hydraulic required depth led diaphragm sealing wall 1 and a sealing sole 3 connected to the base 2 thereof High pressure injection bodies 4.
- the sealing wall base 2 consists of precast concrete parts and points a strength designed for a sufficient load bearing capacity on.
- the sealing wall base 2 could also be used in contractor concrete be executed.
