SU85172A1 - The method of penetration of shafts in shafts - Google Patents

Description

Known methods of sinking shafts in shafts require the construction of a reinforced concrete forshakhty with a collar that perceives the pressure of jacks that crush the supports.

The proposed method of penetration is considerably simplified, since it does not require the construction of expensive reinforced concrete forshakhts, and only vertical forces of soil friction are used to support all the supports.

The drawing shows a general view of the device for carrying out the method.

The device consists of a metal shpunta /, made in the form of a cylinder, the lower part of which is hammered slightly below the surface.

A collar 2 is mounted on the upper part of the crowded schapit. A ring 3 consisting of tubings is assembled on the mounted collar. The ring 3 on the collar is supported on the tongue with bolts 4, which are screwed into the holes of each tubing.

Bolt-taps 5, which abut against a shunt, are screwed into each ring in order to transfer the mountain lateral pressure to a permanent barrel lining, i.e., to a tubing ring.

As the lining deepens, the rings are built up to form permanent lining of the bore shaft.

At the end of the passage of the shaft, all auxiliary facilities; The tongue, collar, and other elements are dismounted, protruded to the surface, and used when driving other stems.

Subject invention

The method of penetrating the shafts of shafts in quicksand, characterized in that a metal tongue is used, the lower end of which is located in stable ground, and the upper end, which receives the weight of a permanent lining, rests on the rings, which grow as the shaft deepens.
