concerning "Procedure for the production of structures in a construction pit"

Addendum to patent ... file number N 20 66% V / 84c

The patent ... file number N 20 664 V / 84c refers to a process for the production of structures in an essentially wall-stiff construction pit from a hardenable resp. Abblndefählgen building material parked with one as permanent formwork trained rubber coat or the like. is filled on the spot with the building material, with the construction pit from its upper edge to the bottom with the approximate outline of the later " Structure produced in a manner known per se and lowered into the construction pit provided with a reinforcement, reaching up to the upper edge of the construction pit, sack-like jacket and subsequently is filled in a known manner with the building material up to at least the top of the building pit. Through the procedure according to patent ... file number N 20 664 V / 84o is a possibility

“If necessary, water-containing construction pits or construction pits containing aggressive liquids or substances can be filled on the spot with a building material, especially concrete. It is irrelevant whether the later building is constantly protected by the used according to the inventive process sleeve or the ⁿ lining coat "- which would take place in case of unzuerrottbaren material - or if the fact into account already worn that the uragebsside the building structure Coat is destroyed over time.

Improvements to the process are patented for the invention ... file number 20 664 V / 84c insofar as a faster insertion of the reinforced jacket is to be made possible.

The object is achieved in that according to the invention The longitudinal bars of the reinforcement are connected to one another by a star-shaped transverse reinforcement before they are lowered into the excavation are in such a way that when lowering the jacket, the reinforcement is wrapped in accordance with the transverse reinforcement and that the jacket before Filling with the building material is inflated as is known per se and brought into contact with the surrounding soil.

The application of this suggestion to a cage consisting, for example, of four LMng irons would mean »that the transverse reinforcement from a real cross or Sternberehrmig exists and that the jacket when it is inserted into the excavation, roughly the rough outline of a cross of the star in cross section. This improvement is essential insofar as overcoming the constant hydrostatic pressure in the case of a »e.g. water-containing or oil-containing excavation on the simplest Way only possible by lowering the deodorant armored coat while, for example, if the jacket is folded in a spiral shape Difficulties can arise around the building, which can be overcome by applying mechanical pressure from above or by prematurely filling the jacket with dsm building material can be.

Secondly, the task is achieved in that the invention

This not only results in faster and safer lowering, as was already the case with the improvement suggested above of the reinforced mantle, but is also at the same time
