Embodiment Construction
[0019] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0020] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a construction method for the pipe curtain segment. 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, and the second layer is located above the first layer; cutting, supporting and pouring the steel pipes of the first layer , after the pouring is completed, check the structural strength of the first layer; when the structural strength of the first layer meets the requirements, cut, support and pour the steel pipes of the second layer; when the structural strength of the first laye...

The invention provides a construction method of a pipe curtain section. The construction method of the pipe curtain section comprises the following steps: dividing a pipe curtain structure into a first layer and a second layer along the vertical direction, wherein the second layer is positioned above the first layer; cutting, supporting and pouring a steel pipe of a first layer, and detecting thestructural strength of the first layer after pouring; when the structural strength of the first layer meets the requirement, cutting, supporting and pouring a steel pipe of the second layer; and whenthe structural strength of the first layer does not meet the requirement, continuing pouring, so that the structural strength of the first layer meets the requirement. According to the technical scheme provided by the invention, the technical problem that a construction method in the prior art can greatly influence the structural strength can be solved.
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...
