Abstract
Abstract Piles or subterranean pile walls are produced by using a pack of parallel tubes, composed of filling tubes closed at the bottom and of collecting tubes open at the bottom, which pack of tubes is driven into the earth, the filling tubes displacing the earth to the side and later being filled with concrete. The collecting tubes collect a part of the earth, thereby enabling its removal, the amount of removed earth being adjusted by pressure air acting on top of the earth cores in the collecting tubes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
178 words
A process of producing piles in earth material, comprising driving-in at the required place a pack of parallel, mutually firmly connected but laterally separated tubes to a predetermined depth, at least one of said tubes, a filling tube, being closed at the bottom, in the course of driving-in displacing the earth material to the sides, other tubes, collecting tubes, being substantially open at the bottom to allow the earth material to enter said collecting tubes in the course of driving-in, closing the collecting tubes at the bottom prior to raising them after the driving-in has been finished, opening the filling tubes at the bottom, filling the filling tubes with pile-forming material, raising the tube pack, and, subsequently discharging the pileforming material through openings at the bottom of filling tubes into the uncased bottom part of the pile space until the pile space is completely filled by the pile-forming material after the tube pack has been completely raised, and emptying the collecting tubes of the raised tube pack of the earth material after displacing it beyond the produced pile.
Claim 2
Dependent Claim
178 words
A process of producing piles in earth material, comprising driving-in at the required place a pack of parallel, mutually firmly connected but laterally separated tubes to a predetermined depth, at least one of said tubes, a filling tube, being closed at the bottom, in the course of driving-in displacing the earth material to the sides, other tubes, collecting tubes, being substantially open at the bottom to allow the earth material to enter said collecting tubes in the course of driving-in, closing the collecting tubes at the bottom prior to raising them after the driving-in has been finished, opening the filling tubes at the bottom, filling the filling tubes with pile-forming material, raising the tube pack, and, subsequently discharging the pileforming material through openings at the bottom of filling tubes into the uncased bottom part of the pile space until the pile space is completely filled by the pile-forming material after the tube pack has been completely raised, and emptying the collecting tubes of the raised tube pack of the earth material after displacing it beyond the produced pile.
Claim 3
Dependent Claim
35 words
A process as set forth in claim 1, comprising adjusting the amount of earth material collected by a collecting tube by pressure air acting from the top on the earth core in the collecting tube.
Claim 4
Dependent Claim
51 words
A process as set forth in claim 1, comprising repeatedly driving-in the tube pack closed at the bottom after a part of the pile space has been filled and the tube pack has been partially raised, and compacting the earth material by exerting pressure on the fresh filling of this space.
Claim 5
Dependent Claim
49 words
A process as set forth in claim 1, comprising driving-in a lateral extension of the tube pack, in the course of its driving-in into a part of the circumference and cross section of a just filled adjacent pile, thereby permitting a continuous production of pile packs and pile walls.
