Abstract

The invention discloses a flexible composite anti-explosion blocking wall, and belongs to the technical field of society public safety. The anti-explosion blocking wall is an unclosed annular body when being unfolded, and comprises a liquid layer and a fiber layer, wherein the liquid layer comprises a folding bag, liquid filled in the folding bag and a reinforcing bar arranged in the folding bag;the folding bag is an unsealed hollow round table when being fully filled with the liquid; the lower end of the folding bag is provided with a liquid inlet valve used for filling liquid into the folding bag and a pressure limiting valve for preventing the pressure in the folding bag from exceeding the set value; the upper end is provided with an air inlet valve and an air outlet valve used for airinlet and air outlet; the fiber layer is a round table-shaped casing with the same central angle as the folding bag, and is sealed in a chinlon bag; the chinlon bag with a sealed fiber layer at the inside is detachably arranged on the outer circumference surface of the folding bag. The flexible composite anti-explosion blocking wall has the characteristics that the storage is convenient; the assembly can be performed at any time; the speed is high; the practicability is high; the anti-explosion equivalent weight is great; no secondary accessory damage exists.

Description

technical field [0001] The invention belongs to the technical field of social public safety, and in particular relates to a flexible composite explosion-proof retaining wall. Background technique [0002] Explosion terrorist attacks and explosion-related criminal offenses have become one of the main threats to public security at home and abroad. Explosion terror has the characteristics of concealment, simple implementation, and large-scale damage, and it is easy to cause long-lasting and widespread terror among the public. It has become the most commonly used and most common form of activity by terrorists today. Therefore, timely and safe disposal of explosives found in various places and protection of surrounding personnel, equipment and buildings are a major problem that public security departments need to solve urgently. [0003] For explosives found in public places, explosion-proof retaining walls can be used for pre-emergency containment. There are generally two type...
