Efficiently recycled profile steel for foundation pit supporting structure

Abstract

The invention discloses efficiently recycled profile steel for a foundation pit supporting structure. The efficiently recycled profile steel comprises a wing plate (1) and a web plate (2), a steel pipe (3) is arranged at the joint of a flange of the wing plate (1) and the web plate (2), a connecting port (3-1) is formed in one end of the steel pipe (3) and used for being connected with an externalhigh-pressure water pipe, a sealing part (5) is arranged at the other end of the steel pipe (3), the bottom end of the sealing part is attached to the side face of the profile steel, and drainage holes (3-2) are formed in the side wall of the steel pipe (3). The problem that profile steel used for foundation pit supporting in engineering construction is not easy to recycle is solved, the steel pipe is welded to the joint of the flange of the wing plate and the web plate, the drainage holes are formed in the side wall of the steel pipe, in the profile steel recycling stage, the end of the connecting port of the steel pipe is connected with the high-pressure water pipe in a matched mode, high-pressure water is sprayed out of the drainage hole to wet a soil body on the surface of the profilesteel, thus the profile steel is easily separated from the surrounding soil body, and the profile steel is efficiently recycled.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a high-efficiency recycled shaped steel used for foundation pit support structures. Background technique [0002] Taking the reinforced cement-soil support structure as an example, the section steel used in the structure should be recycled and reused under certain conditions. Efficient recycling of section steel can reduce project cost. According to estimates, the cost of section steel accounts for about 30% of the cost of the enclosure project. If the section steel can be efficiently and completely recycled, it will bring significant economic benefits. Therefore, urgently need those skilled in the art to develop a kind of novel scheme that solves the problem that the section steel used for foundation pit support in engineering construction is not easy to recycle. Contents of the invention [0003] The object of the present invention is to solve the above-me...
