Method for treating unqualified reinforced concrete piles by using water pressure explosion

Abstract

The invention discloses method for treating unqualified reinforced concrete piles by using water pressure explosion. The method comprises the following steps of step 1, selecting unqualified reinforced concrete piles as the reinforced concrete piles to be treated, and drilling a blast hole in the middle of the reinforced concrete piles to be treated. The method is convenient to operate and capableof improving the construction efficiency, the time required for breaking the reinforced concrete piles can be greatly shortened, the construction progress can be accelerated, the engineering cost issaved, the water bags are arranged, so that civilized construction can be realized, noise and dust pollution generated during construction can be reduced, the water has incompressibility, so that theefficiency of explosives can be improved, a water wedge effect is generated, the blasting time required is short, and environmental protection measures can be taken in a targeted manner; the design isreasonable, the implementation is easy, the engineering cost can be reduced on the premise of ensuring the explosion safety, the cost of machinery, fuel oil and the like generated during engineeringconstruction is greatly reduced, the economic cost is greatly saved, and the method has a great market application prospect.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete pile blasting, in particular to a method for treating unqualified reinforced concrete piles by hydraulic blasting. Background technique [0002] In building construction, it is usually necessary to destroy unqualified reinforced concrete cast-in-place piles. At present, when destroying unqualified reinforced concrete cast-in-situ piles, breaking hammers or pneumatic picks are mainly used in the demolition work to break them manually. During the construction process There are following deficiencies: [0003] (1) The demolition of reinforced concrete cast-in-situ piles generally requires re-construction at the original location, and it takes a long time to use a breaker or a pneumatic pick to cooperate with manual demolition, which seriously affects the construction progress; [0004] (2) The cost of using a breaker or pneumatic pick together with manual removal is high, and the constru...

AI Technical Summary

Problems solved by technology

[0003] (1) The demolition of reinforced concrete cast-in-situ piles generally requires re-construction at the original location, and it takes a long time to use a breaker or a pneumatic pick to cooperate with manual demolition, which seriously affects the construction progress;

[0004] (2) The cost of using a breaker or pneumatic pick together with manual removal is high, and the construction noise lasts for a long time, which is not conducive to civilized construction and environmental protection requirements;

[0005] (3) Dust will be generated in the whole process of breaking reinforced concrete pouring piles by the breaking hammer, which is not conducive to centralized prevention and control in a short time. In view of the above problems, this invention is specially designed to solve them
