Building demolition method using self-expansion effect of expansion agent

Abstract

The invention discloses a building demolition method using a self-expansion effect of an expansion agent. The building demolition method using the self-expansion effect of the expansion agent comprises the following steps that step 1, the number of falling layers, destruction layers and destroying layers of a building to be demolished is calculated; step 2, stand columns of the destruction layersare marked; step 3, pouring holes are formed; step 4, oil storage holes are formed; step 5, expansion agent mixtures are prepared; step 6, the expansion agent mixtures are poured; step 7, openings ofthe pouring holes are closed by sealing devices; and step 8, burning devices are arranged to burn the stand columns, the stand columns are completely destroyed, and the demolition of the building is realized. According to the building demolition method using the self-expansion effect of the expansion agent, the problems of long demolition cycle, high demolition cost and high danger can be solved,and the momentum generated by the self-weight falling from the upper part of the building is used for destroying the entire building, the demolition of the building is realized in safety and controllability modes, the demolition cycle is short, the operation is simple, the demolition cost is low, and the safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of high-rise building demolition, in particular to a building demolition method utilizing the self-expansion effect of an expansion agent. Background technique [0002] The traditional methods of traditional house demolition include manual demolition, mechanical demolition and blasting demolition. Manual demolition of buildings often leads to the accidental collapse of the wall due to uncontrollable factors, causing casualties; and it is inefficient, requires a long construction period, and is expensive. Mechanical demolition is carried out by means of bulldozers or heavy hammers, but the general mechanical height is low, and when high-rise buildings need to be demolished, mechanical demolition cannot be used. Blasting demolition refers to the use of explosives to generate high-temperature and high-pressure gas at the moment of blasting to act externally, thereby disintegrating and breaking buildings and st...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a building demolition method using the self-expansion effect of the expansion agent, which can solve the problems of long demolition period, high demolition cost and high risk, and destroy the whole building by using the momentum generated by the falling of the building above its own weight. Realize the safe and controllable demolition of buildings, the demolition period is short, the operation is simple, the demolition cost is cheap, safe and reliable
