Description

Novel protection system for underground target

Technical Field

The utility model belongs to the technical field of the engineering protection, concretely relates to novel protection system of anti accurate striking of underground target.

Background

Currently, under the information-based condition, the precision guidance (control guidance) weapon is the main striking weapon in modern war, and the precision is continuously improved and the power is continuously increased, so that the important target can be destroyed once being found. The important target is transferred to the underground and a thick protective layer is built, which is an important way for improving the survival capability of the target, but the survival safety of the underground important target still faces a serious challenge as the penetration capability of the accurately guided drilling weapon is continuously improved. There are two main approaches to dealing with the new threat posed by the development of precision guided earth-boring weapons to important targets in the ground: firstly, the thickness of the protective layer is increased; secondly, the structure of the protective layer is improved. The traditional protective structure consists of an elastic shielding layer, a dispersion layer and an enclosure structure; the bullet shielding layer directly consumes the kinetic energy of an incoming weapon or changes the penetration trajectory of the incoming weapon, so that the earth-boring weapon is forced to explode in the bullet shielding layer; the dispersing layer disperses the explosive shock waves and loads of weapons to a larger area, and the load peak value acting on the top plate of the enclosure structure is reduced; the enclosure is the last line of defense for important targets, and damage to the enclosure will directly affect the safety of personnel and facilities inside the important targets. Increasing the thickness of the protective layer mainly means increasing the thickness of the bullet shielding layer, and theoretically, the thickness of the bullet shielding layer can effectively resist all ground weapons, but the increase of the thickness of the bullet shielding layer means that the construction cost is greatly increased and is limited by the expenditure, and the thickness of the bullet shielding layer cannot be increased without limit. On the other hand, the thickness of the protective layer of the actual engineering is limited by the position of the engineering, the topography and the construction conditions, the penetration capability of the existing deep penetration weapon is continuously improved, the protection limit of the traditional protective structure is gradually broken through, and the traditional protective layer seems to catch the elbow when dealing with the novel large penetration weapon, so that the continuous improvement of the protective layer structure is an ideal choice for dealing with the novel accurate guidance ground weapon under the conditions of cost restriction and limited protective layer thickness.

In recent years, in order to improve the penetration resistance of underground targets to accurately guided drilling weapons, researchers carry out a great deal of research on the destruction effect of the drilling weapons, bullet shielding materials, underground building structures and the like, and the penetration resistance of the underground targets to deep drilling kinetic energy is improved. However, the resistance of the bullet shielding material is hardly qualitatively improved, the underground building structure design is hardly broken through in the penetration resistance aspect, and a novel protection structure or a protection system is urgently needed to be developed aiming at the striking characteristic of an accurate guided weapon, so that the target has certain explosion fragment resistance and shock wave resistance while an incoming weapon is forced to be far away from the target explosion, and the survival capability of the underground target is remarkably improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel protection system for underground target, this protection system
