Water screen for rapidly attenuating shock wave in pits

Abstract

The invention provides a water screen for rapidly attenuating shock wave in pits, which is positioned in pits at an exit and entrance of civil air defense engineering. The water screen comprises a row of suspension hooks, a water injection faucet and a flexible water screen pad, wherein, the suspension hooks are pre-embedded in coated concrete on the top of the pits at the exit and entrance of the civil air defense engineering and are arranged along the width direction of the pits at the exit and entrance of the civil air defense engineering; the water injection faucet is arranged on the coated concrete beside the suspension hooks; and the upper part of the flexible water screen pad is equipped with a row of suspension holes, the flexible water screen pad is hung on the suspension hooks through the suspension holes and comprises a cushion with a certain thickness and water poured into the cushion, the cushion is made from a flexible high-strength fiber cloth, and tie strips are connected inside the cushion and between the front face and the rear face of the cushion. The water screen has the characteristics of being simple, convenient and economical, high in war readiness benefit and good in wave resistance effect; and by utilizing the water screen, repeated attack of the explosive shock wave can be resisted, thus the safety of the civil air defense engineering can be greatly improved, and the personnel safety and property safety are well protected.

Description

technical field [0001] The invention relates to a device for blocking explosion shock waves, in particular to an anti-explosion shock wave device installed in tunnels at entrances and exits of civil air defense projects. Background technique [0002] Civil air defense projects are usually used as underground shopping malls, underground garages, underground traffic arteries, etc., and as shelters in wartime to ensure the safety of personnel and property. Due to the limitation of the construction site in the city, and the concept of convenient and quick access to civil air defense projects, the existing civil air defense project entrance and exit tunnels are generally designed to be very short, and the protection ability to the blast shock wave is very low; in addition, when civil air defense projects When it is necessary to switch between peacetime and wartime, the existing methods mostly use measures such as stacking sandbags to improve the anti-blast shock wave capability o...
