Description

 The invention relates to methods for the construction of silo launchers (silos), namely, the reconstruction of silos on the basis of the silos construction, designed for heavy missiles with separable warheads for individual guidance (RGCH IN).

 Known silos, the main building element of which is a mine structure (Malikov VG Mine launchers. M .: Military Publishing, 1975). Such silos imply high construction costs and relatively large timelines for their creation.

 Known silos designed for heavy missiles with rhch IN. In the context of a reduction in strategic offensive weapons (START), such silos are subject to liquidation. In accordance with the procedure provided for in the START Treaty (START-1), upon the elimination of such silos, the protective roof is removed, dismantled or destroyed, and the shaft head and shaft are destroyed by extraction from the ground to a depth of at least 8 m or by explosion to a depth of less than 6 m. Following this, the shaft and the depression formed as a result of extraction from the ground or explosion, fall asleep. In accordance with the START-2 Treaty, it is possible to use parts of silos designed for heavy missiles with RGCH IN as silos for monoblock missiles. Why are silos converted? In particular, to a depth of 5 m they are poured with concrete so that heavy rockets cannot fit there, and the metal structure of the upper part of the shaft is equipped with a restrictive ring.

 Closest to the technical nature of the proposed method is the method of reconstruction of silos, which is carried out in a rocket mine converted into a monoblock missile in accordance with the Treaty on CHB-2 (newspaper "Izvestia", N 67, 10.04.93) [1].

 The known method includes the formation of a mine shaft under a monoblock missile and the installation of a silo shock absorption system in it, in which a transport launch container (TPK) with a rocket is mounted. In this method, a mine shaft for a monoblock rocket is formed from an existing mine shaft for a heavy rocket by reducing the size of the shaft by pouring concrete to a predetermined depth.

 The disadvantage of this method of reconstruction of silos is that it does not imply an increase in the survivability of silos.

 The objective of the invention is to reduce the cost of building silos, reducing the time of its creation, as well as increasing the survivability of silos.

 This problem is solved due to the fact that in the known method of reconstructing silos, including the formation of a mine shaft for a monoblock missile and the installation of a silo shock absorption system in it, according to the invention, a mine filled with soil from a silo launcher is used to form a mine shaft, for which sinking to a given depth is carried out with a predetermined diameter with partial disassembly of the upper part of the shaft and excavation from the shaft of the shaft. Then, on the existing part of the mine shaft, the upper part of the silo launcher is equipped with a removable protective cover for the metal structure. Next, in the shaft of the mine set the depreciation system of the silo launcher. After that, above the protective cover along the axis of the shaft of the mine, a channel is formed of easily destructible material, after which production is backfilled. Moreover, after placing the transport and launch container in the silo launcher, the said channel is filled with filler blocks of a material similar to the aforementioned.

 Along with this, in parallel with the filling of the mine, the tunnel lining is dismantled. As a result of seismic impact on the path of extension of the TPK with a rocket, there may be interconnected building structures of the support lining. Dismantling the tunnel lining eliminates this possibility and improves the reliability of silos when launching a rocket.

 The technical result of the use of the invention is that as a result of the reconstruction of the silo launcher from near-surface convertibility to a deepened silo, which allows to increase its survivability under the influence of ammunition of various types. At the same time, the in-depth arrangement of silos allows increasing the level of protection against sabotage and extremist groups, as well as the level of nuclear and environmental safety. Along with this, through the use of existing mine shafts, a significant reduction in capital costs and construction time is achieved, as well as the almost complete use of the infrastructure of the existing silos.

 In FIG. 1 shows a silo launcher reconstructed as a monoblock missile, a longitudinal section; in FIG. 2 - silo launcher before reconstruction, longitudinal section.

 The proposed method of reconstruction of silos is implemented as follows.

 In an embodiment of the invention, a silo from a number of decommissioned in accordance with the START Treaty (START-1) is being reconstructed under a monoblock missile. In the initial state, the surviving part of the fortification structure 1 silos filled with soil 2.

 For the formation of the shaft of a silo shaft under a monoblock missile, a layer 3 of silos filled with soil is used, for which a penetration is carried out to a depth corresponding to the condition for placement in a silo of a TPK with a monoblock rocket 4. In this case, the upper part of the shaft of the shaft and the adapter block are partially disassembled. corresponding to the existing tunnel (technological) roof support 6.

 After this, excavation is carried out from the shaft of the mine. Then, the metal structure 7 of the upper part of the silo with the organized entrance 8 to the fortification structure and a removable protective cover 9 is mounted on the existing part of the shaft of the mine 3. The metal structure of the upper part of the silo is concreted, in particular, the junction between the metal structure and the existing part of the shaft of the mine is monitored.

 Inside the mine, a silos 10 depreciation system is installed.

 After that, over the filming protective cover 9 along the axis of the shaft of the mine form the technological channel 11 from readily destructible material, such as sand concrete. After placement in the silos of a transport and launch container with a missile, the technological channel 11 is filled with filler blocks 12 of material similar to the aforementioned. The implementation of the technological channel and filler blocks of readily destructible material provides a reduction in the load on the launcher during nuclear impact, as well as provides the necessary conditions for power forcing when extending the TPK from the rocket to the day surface.

 Then make backfill production. In an embodiment of the invention, the free space of the mine is successively filled with an elastic-flexible layer 13, for example, of expanded clay impregnated with petrolatum, a layer of crushed stone 14 and a layer of soil 15 identical to the surrounding soil. The resilient interlayer absorbs part of the mechanical energy of a seismic blast wave from a nuclear explosion.

 A layer of crushed stone increases the protection against penetrating blocks of conventional ammunition.

 In parallel with the filling of the mine, sequential dismantling of the tunnel support 6 is carried out. In principle, this is not mandatory. However, the dismantling of the lining, excluding the possibility that interconnected building structures may appear on the path of the extension of the TPK with the rocket as a result of seismic effects, can improve the reliability of silos during rocket launch.

 After reconstructing the silos, when extending the TPK with the rocket from the shaft of the shaft through the protective cover 9, the filler blocks 12 are forced through and the TPK through the technological channel 11 comes to the day surface, where after launching the cover 9 the rocket is launched.

 Thus, as a result of the reconstruction, the silo-launcher from the near-surface turns into a deepened silo, which makes it possible to increase its survivability under the influence of ammunition of various types, as well as to increase the level of nuclear and environmental safety. Moreover, the proposed method through the use of existing mine shafts provides a reduction in costs and construction time of silos.
