The present invention provides a construction method for a transfer channel that passes through a pipeline. Excavation is carried out at the beginning of the transfer channel to the bottom of the end of the existing pipeline that is close to the beginning, and Construction of the primary support structure in the excavated transfer channel; monitoring the settlement of the ground surface and the existing pipeline and the deformation of the primary support structure After the settlement and the deformation of the primary support structure are stable, excavation is continued to the terminal of the transfer passage by the middle partition method. The invention solves the problem that the traditional tunnel construction method is used to construct the transfer passage passing through many pipelines, which will easily lead to the settlement of many pipelines, the excessive shape and the damage of many pipelines.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a construction method for a transfer passage passing through a pipeline. Background technique [0002] The subway has become the most indispensable part of citizens' daily life, and new subway lines need to be added every year to meet people's needs for subway attendance. With the increase of the number of lines, it is necessary to build transfer channels to realize the connection between different line platforms. With the increase of the number of stations, there are more and more transfer channels located in the existing pipeline-intensive areas of the city. How to effectively ensure the safety of the surrounding pipelines is the focus and difficulty of the project. [0003] In particular, the transfer channel needs to pass through many pipelines (such as heat pipes, rainwater pipes, and sewage pipes), and the bottom of many pipelines is very close to the vault of ...
