Abstract

The invention relates to the field of pipe jacking construction, in particular to a pipe jacking construction method and aims to solve the technical problem of failure in application of pipe jacking methods in the prior art to large-gradient longitudinal curved pipe jacking construction. The method includes: constructing a working well and a receiving well; mounting construction equipment for pipe jacking construction; setting up and implementing a gyroscope guide system for pipe jacking construction; controlling a pipe jack for jacking; adopting an automatic lubricating system for lubricating and resistance reducing construction of a tunnel in pipe jacking construction; arranging an intermediate jacking station in the tunnel to increase a jacking force, wherein the intermediate jacking station is a locally and remotely controlled split intermediate jacking station; subjecting the pipe jack to cutthrough treatment. The pipe jacking construction method is applicable to large-gradient 'V'-shaped longitudinal curved pipe jacking construction.

Description

technical field [0001] The invention relates to the field of pipe jacking construction, in particular to a pipe jacking construction method. Background technique [0002] Pipe jacking construction is a non-excavation construction method, and it is a pipeline burying construction technology that does not excavate or excavates less. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the earth away. After one section of pipe has been jacked into the soil layer, the second section of pipe will continue to be jacked. Its principle is to push the tool pipe or roadheader from the working pit through the soil layer to the receiving pit by means of the thrust of the main top oil cylinder, the pipeline room, and the relay room. The pipeline is buried between the two pits immedia...
