Pipe jacking machine capable of being disassembled in pipeline

Abstract

The pipe jacking machine capable of being disassembled in the pipeline comprises a machine body, a machine core, a main cutter disc and edge cutters, the main cutter disc is rotationally connected to one end of the machine body, the machine core is fixed in the machine body, the power output end of the machine core is fixedly connected with the main cutter disc, and the two or more edge cutters are evenly connected to the side edge of the main cutter disc in a clamped mode. Through the cooperation of the main cutter head and the edge cutter, after the pipe jacking machine jacks a pipeline to a proper position, the edge cutter is detached from the main cutter head, so that the main cutter head, the edge cutter and the machine body retreat from the end of the pipeline and are taken out, the defect that traditional integral mechanical pipe jacking equipment cannot be detached in a hole is overcome, and the pipe jacking machine is simple in structure, convenient to operate and low in cost. And on-site assembly and disassembly are very convenient, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to the field of pipe jacking devices, and more particularly, to a pipe jacking machine that can be disassembled in a pipeline. Background technique [0002] Existing trenchless technologies can be divided into three types: 1. Mud-water balance pipe jacking technology; 2. Earth pressure balance pipe-jacking technology; 3. Manual earth-digging pipe-jacking technology; Balanced pipe jacking machine, the body is integral, the pipe jacking machine is slightly larger than the outer diameter of the pipe by 10-15mm, so when the pipe jacking machine reaches the end point, it is usually necessary to set up a receiving well to take out the pipe jacking head; there are no conditions on site When setting the receiving well, the pipe jacking method is generally completed by the manual advance excavation method. The manual advance excavation method is low in efficiency, easy to collapse, and has a great potential safety hazard. SUMMARY OF THE ...

Problems solved by technology

[0002] The existing trenchless technology can be divided into three types, 1. Slurry balance pipe jacking technology; 2. Earth pressure balance pipe jacking technology; 3. Manual excavation pipe jacking technology; Balanced pipe jacking machine, the fuselage is integral, and the pipe jacking machine is slightly larger than the outer diameter of the pipe by 10-15mm. Therefore, when the pipe jacking machine reaches the end point, it is usually necessary to set up a receiving well to take out the pipe jacking head; there is no condition on site When setting up the receiving shaft, the pipe jacking method is generally completed by manual advance excavation method, which has low efficiency of pipe jacking, is prone to collapse, and has great potential safety hazards
