Embodiment Construction

[0027] 1. According to the explosion shock wave, the facility structure design and parameter selection:

[0028] When the charge explodes in the air, due to the huge pressure of the explosion products, the explosion products expand rapidly outward. The expanding explosion product acts like an accelerating piston compressing the surrounding air. Because the explosion product initially compresses the surrounding air medium at a very high speed, its pressure, density and temperature suddenly increase, forming an initial shock wave with a high pressure (about 10 8 Pa order of magnitude). As the explosion products continue to expand, there are sparse waves propagating inward along the explosion products. As the sparse wavefront propagates to the center of the explosion, the pressure at the center of the explosion begins to drop.

[0029] For different distances, the effect on the target is also different. In the shortest distance from the center of explosion, the target is main...

Abstract

The invention discloses a safety protection method used for explosion and destruction of waste explosives. The waste explosives are arranged in a specific explosion and destruction apparatus. The specific explosion and destruction apparatus comprises a main body structure (1) arranged on a foundation structure (5). Both the main body structure (1) and the foundation structure (5) are made of reinforced concrete. A sandy soil protection layer (6) is arranged on the foundation structure (5) in the main body structure (1). A lining structure (7) is arranged on the inner wall of the main body structure (1). According to the method, shock waves generated by the explosives can be effectively absorbed and reduced through structural design, the destruction effect of fragments is controlled to prevent explosion fragments from flying off, and the service life of a facility is prolonged by replacing the lining.

Description

technical field [0001] The invention belongs to the field of detonation, and in particular relates to a structural design method of an explosive destruction device for waste explosives. Background technique [0002] During the explosive destruction of waste explosives, because the explosives explode on the ground in the destruction facility, it will cause damage to the entire structural facility. The part acting in the direction of the air will damage the surrounding targets in the form of explosion shock waves and explosion products, and the part acting in the direction of the ground will carry out energy propagation and damage in the form of seismic waves. These two failure loads have a major damage effect on the structure of the entire facility, so how to weaken the shock wave and seismic wave and remove and remove the explosion products to ensure the safety of the facility is the key point of the structural facility. At the same time, the effect of the explosion product...
