Abstract

Usage: in underground construction during the construction of underground enterprises, etc. SUMMARY OF THE INVENTION: A vertical chamber is created in the rocks filled with a loose bookmark on the surface of which a large object is placed. A bookmark is released from the camera. After partial immersion of the object, the release of the bookmark is stopped, the wellhead of the chamber is filled with the bookmark to the surface level. A second object is mounted on the bookmark layer, then bookmark release from the chamber is resumed until the objects reach the design depth. 2 ill.

Description

The invention relates to underground construction and can be used to create, for example, industrial underground enterprises, etc.

An object of the invention is to increase the useful volume of a chamber.

In FIG. Figure 1 shows the position of the bodies at the beginning of their immersion: in Fig. 2, the same, at the end of the immersion.

The essence and example of a specific embodiment of the method is as follows.

In strong stable rocks 1 underground workings 2 pass, using which, form the bottom of the chamber 3, including the exhaust workings, funnels 4. The rocks within the chamber 3 are destroyed by explosions and released through the funnels of the bottom of the chamber 3. At the same time, the chamber 3 is filled loose bookmark 5 of a homogeneous non-caking material, for example sand, expanded clay, slag, etc. But the surface of the bookmark is 5 in

In the vicinity of the mouth of the chamber 3, a large-sized object 6 is installed, for example, a chemical reactor placed in a reinforced concrete building. Then the release of the bookmark 5 through the workings of the bottom of the chamber 3 begins. Simultaneously with the descent of the object 6, a bookmark is served at the mouth of the chamber, and after the layer of the bookmark 5 is formed on the surface of the object 6, the release of the latter from the chamber 3 is stopped. After that, a second object 8 is installed on the surface of the bookmark layer 7, for example, a chemical reactor in a shell, the operation of which is possible only with the reactor 6. Then, the release of bookmark 5 from the chamber 3 is resumed and the objects 6 and 8 are launched together, filling the empty volume with the bookmark chambers 3. When the object 6 reaches the design depth, the release of the bookmark 5 is stopped, it is injected with a hardening solution, excavations 9, 10 are carried out to objects 6 and 8, the bodies are opened and the operation is started &

objects b and 8, which can be connected by technological channels 11, 12.

During the descent of objects b and 8, the bookmark layer 7 is pressed between them, which excludes a significant change in their relative position during the descent. In addition, objects b and 8 can be connected by flexible connections (not shown). The thickness of the layer 7 can be 5-10 m, depending on the dimensions of the objects 6 and 8. The pressing of the bookmark layer can be carried out by tensioning the flexible connections.

SUMMARY OF THE INVENTION A method of immersing large objects in a rock, including forming a vertical chamber whose mouth extends to the surface, forming underground outlet openings from the bottom of the chamber, filling the chamber with bulk material, placing a large object on the bulk material, and discharging material through the underground outlet and forming above the submerged bookmark subject matter. that, in order to increase the useful volume of the chamber, the bookmarks are formed from bulk material to the mouth of the chamber, and after its formation, the release of bulk material is stopped, the next 5 objects are placed on the surface of the bookmark, after which the release of bulk material is resumed. 0 / 3.
