Inclined protection structure and using method

Abstract

The invention discloses an inclined protection structure and a using method. The inclined protection structure comprises an inner tunnel, an outer tunnel and a tunnel wall, one side of the tunnel wallis connected with a door frame, and a door body is connected between the inner tunnel and the outer tunnel; the end, close to the door body, of the outer tunnel is provided with a wave-absorbing chamber; and a wave-absorbing wall is connected to the inner surface of the tunnel wall. According to the device, a protective door plate with a certain inclination angle is arranged, the impact of shockwaves on the front face of the door plate is reduced, the wave-absorbing chamber is built in the tunnel at the front end of the door plate, the shock waves are scattered into the wave-absorbing chamber through the door plate, and the shock waves are dispersed and absorbed by through the wave-absorbing wall in the wave-absorbing chamber. The inclined protection structure solves the problems of poorwave-absorbing effect and poor use convenience of the existing underground civil air defense work wave-absorbing technology and has the advantages of no need of frequent maintenance, good wave-absorbing effect, capability of being put into use at any time and no need of preparation work before use.

Description

technical field [0001] The invention belongs to the technical field of underground civil air defense works, and in particular relates to an inclined protective structure and a use method. Background technique [0002] At present, the protective structures of civil air defense fortifications and military caverns at home and abroad are traditional protective structures perpendicular to the side walls of the cave entrances. Considering the strength of the civil structure and construction economy, this layout is the optimal solution. However, from the analysis of protective effectiveness, there is room for improvement in this structure. In modern warfare, the shock wave after the explosion often causes huge damage. In the small underground civil air defense fortification, the powerful shock wave often rebounds and superimposes repeatedly, causing damage to the building structure, thereby threatening the safety of people's lives. Therefore, how to eliminate the explosion shock ...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide an inclined protective structure and its use method. The device reduces the frontal impact of the shock wave on the door panel by setting a protective structure panel with a certain inclination angle, and builds a wave-absorbing chamber in the tunnel at the front end of the door panel. The shock wave is scattered into the wave-absorbing chamber through the door panel, and the wave-absorbing wall in the wave-absorbing chamber is used to disperse and absorb the shock wave; it solves the problems of poor wave-absorbing effect and poor use convenience of the existing underground civil air defense fortification wave-absorbing technology, and has the advantages of not requiring frequent use Maintenance, wave suppression effect is good, can be put into use at any time, without the characteristics of preparatory work before use
