Abstract
A process for producing a pile in the earth with a pipe is provided. The pipe is provided internally with a conduit, which emerges on the bottom side of the pipe, for feeding pile-forming, hardening material into the earth. The pipe is introduced into the earth, and the pipe is removed from the earth while a space created by the removal of the pipe is simultaneously filled with the pipe-forming, hardening material.
Claims18
A process for producing a pile in the earth with the aid of a pipe, the pipe being provided internally with a conduit, which emerges on the bottom side of the pipe, for feeding pile-forming, hardening material into the earth, the process comprising:
- introduction of introducing the pipe into the earth,
- removing the pipe from the earth and, as the pipe is being withdrawn, simultaneously filling an underlying space, created by the removing of the pipe, with the pile-forming, hardening material,
- wherein the conduit, as the pipe is introduced into the earth, is closed off on the bottom side of the pipe by means of a shut-off valve which is close to the bottom side of the conduit and operated from ground level, and is full of pile-forming, hardening material, said operation of the shut-off valve being independent from the presence of the pile-forming, hardening material,
- immediately after the pipe reaches its lowest point, the shut-off valve is opened from ground level and the pile-forming, hardening material is pumped via the conduit, as the pipe is withdrawn, into the underlying space which is thereby created, and that the formed pile has a diameter less than 25 cm, and that the pumped pile-forming, hardening material contains no solid constituents of more than 16 mm in diameter.
A device for making a pile in the earth, comprising a pipe to be placed in the earth and provided internally with a conduit for feeding a pile-forming, hardening material into the earth, wherein the conduit on one end is permanently provided in the pipe with a shut-off valve close to a bottom end of the pipe the shut-off valve, is operable from ground level, and on an other end is connected to a pump, and in that at least a part of the conduit which extends between the pipe and the pump is of flexible construction, wherein operation of the shut-off valve is provided at the ground level and independent of the presence of pile-forming, hardening material.
A process for making a construction, comprising
- making a peripheral edge made from concrete material and supported by driven, screw or other piles of more than 20 cm in diameter,
- erecting a number of foundation piles within the peripheral edge,
- pouring a concrete floor upon the foundation piles,
- wherein each pile is produced in the earth with the aid of a pipe, the pipe being provided internally with a conduit, which emerges on the bottom side of the pipe, for feeding pile-forming, hardening material into the earth, the process comprising:
- introducing the pipe into the earth, having the conduit with the pile-forming, hardening material therein and a shut-off valve close to the bottom side of the end,
- removing the pipe from the earth and, as the pipe is withdrawn, filling a space thus created by the withdrawn pipe, with the pile-forming, hardening material, upon opening of the shut-off valve which is operated from ground level independent of the presence of the pile-forming, hardening material in the conduit.
