Description

The present invention relates to the field of underground civil engineering structures and can be used as a mine structure launcher increased stability.

Known mine structure containing a protective device and the shaft of the shaft, and the protective device is fixed in the upper cut of the shaft of the shaft, which for strength is made with a thickening [1]. This construction was used in mine launchers of first-generation rockets as one of the simplest in design, however, the solidity of the shaft of the shaft does not allow to control the uniform distribution of the reinforced concrete solution along the length and circumference, which leads to a decrease in the strength of the barrel walls.

The closest in technical essence to the claimed invention is a mine structure containing a protective structure, an upper suspension ring, a base ring, a device for mounting a rocket, a cushioning system and a protective cover [2]. This structure provides missile protection against increased loads due to the introduction of these rings and twelve stiffeners, evenly spaced along the height of the shaft walls of the shaft. The main disadvantage of this mine structure is the complexity of the design and the high cost of the shaft. In addition, the dismantling of the monolithic shaft of the mine is difficult.

The aim of the proposed solution is to increase the stability of the mine structure and simplify its installation and dismantling.

The required technical result is achieved by the fact that the mine structure contains a protective device and a metal shaft of the shaft of a toroidal shape. The shaft of the shaft is made collapsible, containing n identical in size liners and is equipped with a base of the shaft, the diameter of which exceeds the diameter of any liner, with the upper cut of each liner and the base of the barrel endowed with an internal groove, and the lower cut of each liner with an external groove, which provides a protrusion in the lower part of the liner . At the same time, the depths and heights of the indicated grooves of all the liners are respectively equal, and the values of their diameters allow tight assembly between the touching surfaces of the liners. The n-th liner with the specified protrusion is installed in the inner groove of the base of the barrel, each of the remaining n-1, n-2, n-3, ..., the 1st liner is installed with the protrusion in the inner groove of the liner, the number of which is one less, the lower surface of the protective device is provided with a shoulder along the entire circumference (the size of the shoulder equal to the dimensions of the said inner recess) and placed on the upper cut of the first liner, and the upper surface of the protective device is located at the same level with the ground surface.

The execution of the mine shaft collapsible, containing n liners allows you to speed up the installation and dismantling of the mine structure and simplify the transportation of the structure to the installation site. In addition, the composite structure of the barrel allows for unification of mine structures.

The presence of the base of the shaft of the mine allows you to increase the stability of the mine structure to the effects of loads arising from the appearance of a shock wave of a nuclear explosion.

As will be shown below in the description of the construction of the mine structure, all the elements used in it are standard for civil engineering structures, therefore, the proposal meets the requirements of industrial applicability.

The invention is illustrated in the drawing. Figure 1 shows the appearance of a mine structure, for a special case with the number of inserts n = 4. Figure 2 shows a bottom view of the protective device. Figure 3 presents a bottom view of the liner. Figure 4 shows a top view of the base of the shaft of the mine.

The mine structure 1 contains (Fig. 1) a protective device 2 with a shoulder 2-1, made along the entire circumference of the lower surface of the protective device, a first insert 3 with an inner recess from the side of the upper surface 3-1, which coincides in location and size with the shoulder 2 -1 protective device 2 and an external undercut from the bottom surface 3-2; the second insert 4 with an internal undercut from the side of the upper surface 4-1, matching in location and size with the external undercut 3-2 of the insert 3 and the external undercut from the side of the lower surface 4-2; a third insert 5 with an internal undercut from the side of the upper surface 5-1 and an external undercut from the side of the lower surface 5-2; the fourth insert 6 with an internal undercut from the side of the upper surface 6-1 and an external undercut from the side of the lower surface 6-2 and the base of the shaft of the shaft 7 with an internal undercut 7-1.

The inner grooves 3-1,4-1, 5-1, 6-1 and 7-1, respectively, of the liners 3, 4, 5, 6 and the base 7 are designed to ensure alignment of these liners and the formation of a single shaft structure. Their dimensions allow tight-fitting assembly between the contacting surfaces of the liners. External grooves 3-2, 4-2, 5-2, 6-2 of inserts 3, 4, 5 and 6 together with the corresponding internal grooves 3-1, 4-1, 5-1, 6-1 and 7-1 provide fortress and structural strength of the shaft of a mine structure 1.

Figure 2 shows a bottom view of the protective device 2 with an indication of the inner diameter of Dv1, the average diameter of Ds1 and the outer diameter of Dv1. Figure 3 shows a bottom view of any of the n inserts indicating the internal Dv2, average Ds2 and external Dn2 diameters. Figure 4 shows a top view of the base 7 with an indication of the average diameter of the last liner Ds6 and the outer diameter of the base Dn7-2. From the presented drawings it follows that the inner diameters:

average diameters:

and outer diameters:

respectively equal, and the diameter:

where Dv, Ds and Dn are the inner, middle and outer diameters of the indicated components of the mine structure 1, respectively, while Dv is the diameter of the shaft opening, Ds is the diameter of the outer and inner grooves of the surface of the liners and the base, Dn is the diameter of the outer surface of the shaft, To - base diameter.

Mine construction is applied as follows. When determining the location of the launcher, a pit breaks out into which the mine structure 1 is installed in the sequence: the base of the shaft of the mine 7, the last insert, then all subsequent n-1, n-2, ... - inserts. After the installation of the mine structure 1 is completed, a rocket is installed in it and preparatory operations are carried out with equipment, on readiness of which a protective device 2 is installed on the upper surface of the first liner (Fig. 1 liner 3), while its shoulder 2-1 enters the inner groove 3 -1 of the first insert 3. The prepared missile is in the mine structure of the launcher on duty; further use of the launcher is carried out in accordance with established rules.
