PROCEDE ET DISPOSITIF DE FABRICATION D'UN CORPS DE FONDATION EN BETON DANS LE SOL

摘要

The essence of the invention consists in the fact that the soil (10) is loosened at the location of the foundation body to be constructed and monolithic concrete (13) is injected under the loose soil mass (11), whereby the loosened soil is displaced from the space (12) containing the loosened soil and/or is removed in another manner, and at the same time the foundation body is formed once the space is filled with concrete. The apparatus is provided with a drilling tool and a concrete pump (7) and is characterised in that the drilling tool is formed by a screw disc (5), the connecting rod (4) of which can be attached to the rotary device (3) and the concrete pump and is designed as a pipe for delivering the concrete. The advantage of the solution according to the invention lies in the fact that a foundation body of first-class quality and with high strength values can be produced efficiently and quickly. <IMAGE>
