Problems solved by technology

[0004] However, the honeycomb structure currently used in explosion-proof walls is a prefabricated hollow honeycomb structure. There is no filler in the explosion-proof wall. Under the air shock wave load caused by explosives, the explosion-proof wall has a large amount of deformation and weak impact resistance.

Abstract

The invention discloses a prefabricated honeycomb blast wall and a construction method thereof, and belongs to the explosive blast resistance technology. The prefabricated honeycomb blast wall includes a honeycomb sandwich layer (3), panels (1) and a connecting element (4) and further includes sand (2), the honeycomb sandwich layer (3) is three-dimensional intensive honeycomb cells which are madeof metal or hard polymers, and the honeycomb cells are filled with the sand (2); and the upper surface and the lower surface of the honeycomb sandwich layer (3) are covered with the panels (1), and the panels (1) and the honeycomb sandwich layer (3) are combined and fixed through the connecting element (4). The construction method includes the steps of assembly or unfolding of the honeycomb sandwich layer, installation of the connecting element, filling of the sand and covering of another panel and assembly with the connecting element. The prefabricated honeycomb blast wall and the construction method thereof have the advantages that the deformation under the action of explosive shock waves is reduced, and the anti-shock capacity is improved.

Description

technical field [0001] The invention belongs to anti-explosion impact technology, in particular to an assembled honeycomb explosion-proof wall and a construction method thereof. Background technique [0002] In urban gas stations, gas stations, flammable and explosive product production workshops, warehouses and other places prone to explosion, as well as in modern combat, anti-terrorism, peacekeeping and other military operations, explosions seriously threaten personal and property safety. With the rapid development of modern cities, safety issues have become more and more concerned about people. At present, most of the anti-explosion measures implemented for explosive places and traditional field fortifications adopt the method of manually filling sandbags, but this method has low efficiency, heavy workload, difficult withdrawal and low maneuverability. [0003] The honeycomb structure is made according to the bionics principle of natural honeycomb structure. Compared wit...
