Abstract

The invention provides a construction method of the pipe curtain section, the construction method of the pipe curtain section includes: dividing the pipe curtain structure into the first layer and the second layer along the vertical direction, the second layer is located above the first layer; Cut, support and pour the steel pipes on the first layer, and test the structural strength of the first layer after the pouring is completed; when the structural strength of the first layer meets the requirements, cut and support the steel pipes on the second layer and pouring; when the structural strength of the first layer does not meet the requirements, continue pouring to make the structural strength of the first layer meet the requirements. The technical solution provided by the invention can solve the technical problem that the construction method in the prior art will greatly affect the structural strength.

Description

technical field [0001] The invention relates to the technical field of construction of pipe curtain sections, in particular to a construction method of pipe curtain sections. Background technique [0002] At present, the pipe jacking construction technology is a non-excavation construction method, through which the pipeline can be buried with little or no excavation. When the pipe jacking construction process is working, the jacking force generated by the pipe jacking machine is used to overcome the friction between the pipe and the surrounding soil, so as to push the pipe into the soil layer according to the designed slope and transport the earth away. With the work of the pipe jacking machine, the pipe will pass through the soil layer from the working well and enter the receiving well. [0003] When carrying out pipe jacking construction on the soil layer with pipe curtain sections, it is necessary to cut the pipe curtain sections so that the shield machine can continue t...
