Method for cutting, removing and recycling deep foundation pit concrete near river

Abstract

The invention discloses a method for cutting, removing and recycling deep foundation pit concrete near a river, and belongs to the technical field of building construction. The method for cutting, removing and recycling the deep foundation pit concrete near the river comprises the following steps that early-stage preparation work is carried out at a deep foundation pit near the river; the cuttingcross section of an inner support of the deep foundation pit is determined; supporting steel bars are used for supporting the inner support; hoisting holes are drilled in supporting beams of the innersupport, and are used for hoisting and transporting after cutting; the installation position of a rope saw cutting machine is determined according to the cutting cross section of the inner support, and static force cutting is carried out on the cutting cross section of the inner support; the supporting beams of the cut inner support are completely conveyed to a construction site through the hoisting holes; and the supporting beams, which are transported out, of the inner support are recycled. The method for cutting, removing and recycling the deep foundation pit concrete near the river is efficient, safe, environment-friendly, low in vibration, low in noise, free-dust, small in influence on surrounding environment, and low in environmental pollution, and can effectively reduce the construction waste.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for cutting, removing and recycling concrete of a deep foundation pit near the river. Background technique [0002] With the continuous development of cities and the continuous improvement of living standards, people's requirements for housing comfort and functionality continue to increase. Therefore, more and more projects are located in densely populated, urban core business districts or near the river. And built. Such projects are usually large-scale comprehensive projects integrating business and housing in order to maximize the use of limited land. This kind of large-scale building makes the deep foundation pit project bigger and bigger, and the safety of the foundation pit is more and more important. The removal of the foundation pit support is the top priority of the foundation pit safety. Traditional support removal methods generally use mechanica...
