Description

Senkbrunnengründung mit Druckluft. Die Erfindung betrifft eine Senkbrunnengründung mit Druckluft. Das Neue besteht darin, daß ein Senkbrunnen zunächst bis auf eine mit gesundheitlich zulässigem Luftdruck erreichbare Tiefe abgesenkt wird, worauf eine an dem Senkbrunnen lösbar sitzende Senkschneide unter Aufrechterhaltung des zulässigen Luftdrucks durch Druckwerkzeuge, die sich gegen den Senkbrunnen abstützen, unter allmählichem Aufbau eines weiteren unteren Senkbrunnens auf der Senkschneide abgesenkt wird. Der Senkbrunnen a besitzt unten eine Senkschneide c, die. anfänglich gemeinsam mit ihm abgesenkt wird. Zwischen der Senkschneide c und dem Senkbrunnen a befindet sich ein Zwischenraum, in dem die Druckwerkzeuge d untergebracht sind. Die umschließende Kammerwand e, die mit dem Senkbrunnen a und der Senkschneide c dicht verbunden ist, verhütet, daß durch den Zwischenraum Erdboden oder Wasser in den Arbeitsraum eindringt oder umgekehrt Druckluft aus ihm entweichen kann. Ist der Senkbrunnen a bis auf eine Tiefe abgesenkt, die er mit gesundheitlich zulässigem Luftdruck erreichen kann, so wird die Senkschneide c von der Kammerwand e gelöst und mit den Druckwerkzeugen d ein Stück abwärts gedrückt. In dem Zwischenraum zwischen den Druckwerkzeugen d1 beginnt darauf der Brunnenunterteilaufbau auf der Senkschneide c. Auf diese pfeilerartigen Erhöhungen werden nun Druckwerkzeuge einer zweiten Gruppe d2 gesetzt, die den weiteren Aufbau des unteren Senkbrunnens b an den Stellen, wo die Druckwerkzeuge der ersten Gruppe standen, gestatten. Man kann also ohne Steigerung des Luftdrucks nunmehr den unteren Brunnen weiter vortreiben, wobei der obere Brunnen ein geeignetes Widerlager bildet.Sink well foundation with compressed air. The invention relates to a sink well foundation with compressed air. The novelty is that a sink well is initially except for one depth attainable with health-permissible air pressure is lowered, whereupon a countersunk cutting edge detachably seated on the sink well while maintaining the permissible air pressure by means of pressure tools that are supported against the sink well, with the gradual build-up of another lower sink well on the countersink cutting edge is lowered. The sink well a has a countersink at the bottom c, the. is initially lowered together with him. Between the countersink c and the sink well a is a space in which the printing tools d are housed. The enclosing chamber wall e, which is connected to the sink well a and the countersink c is tightly connected, preventing that through the gap Soil or water penetrates into the work space or, conversely, compressed air from it can escape. Is the sink well a lowered to a depth that it is with health-permissible air pressure can reach, the countersink cutting edge c of the chamber wall e released and pressed down a little with the pressure tools d. In the space between the pressure tools d1, the construction of the lower part of the well begins on the countersink c. Pressure tools are now placed on these pillar-like elevations a second group d2 set, which is the further construction of the lower sink well b in the places where the printing tools of the first group were located. Man can now drive the lower well further without increasing the air pressure, the upper well forms a suitable abutment.
