Abstract

The invention relates to the field of engineering construction pipeline laying, in particular to a construction method for controlling sliding of a slope section of an underground pipeline. The method includes the steps of foundation pit enclosure construction and foundation pit side wall and top plate construction, and is characterized by further comprising foundation pit inside construction, wherein foundation pit inside construction includes the steps of foundation pit earth excavation, supporting structure building and foundation pit supporting system erection. In the step of foundation pit earth excavation, a foundation pit earth base is excavated into a step shape and is provided with structural piles; the foundation pit earth base is cleaned and leveled; a concrete cushion layer is poured for the first time on the bottom face of a foundation pit bottom plate; end face blocking walls of the foundation pit bottom plate are built; secondary concrete pouring is carried out on the bottom face of the foundation pit bottom plate; concrete pouring is carried out on the foundation pit bottom plate. According to the method, the angle of the base friction surface of the slope section is changed, so that the problem that upper slope section pipelines slide during deep foundation construction is solved, construction cost is lowered, construction process is accelerated, and construction quality is guaranteed.

Description

technical field [0001] The invention relates to the field of pipeline laying in engineering construction, in particular to a construction method for controlling slippage of slope sections in underground pipeline corridors. Background technique [0002] When the comprehensive pipe gallery set up on the municipal road crosses the level intersection of the road, if there are important pipelines (such as gas pipelines) passing through the intersection and crossing the slope section of the comprehensive pipe gallery, it is set on the upper part of the pipe gallery and is planned to be laid before the pipe gallery. Under normal circumstances, the pipe gallery should be constructed before the important pipelines. Therefore, the construction also forms a situation of "shallow first and then deep". The pipe gallery will have a downward trend, which will pose a threat to the safety and stability of the upper foundation and pipelines that have been constructed. Contents of the in...
