Municipal pipe jacking structure and construction method thereof

Abstract

The invention belongs to the field of pipe jacking, and particularly relates to a municipal pipe jacking structure and a construction method thereof. The municipal pipe jacking structure comprises a barrel, tool aprons A, a tool bit, tool aprons B, a power device and the like, wherein the barrel is internally provided with a round fixing plate A, a shaft A is rotationally arranged in a shaft groove A at the center of the fixing plate A in a matched mode, and the shaft A is driven to rotate by the power device installed in the barrel; a drill bit drills a working surface of a hard rock stratumand conducts further broadening, knocking and breaking on drilled holes, thus, the tool bit on the tool aprons A and the tool aprons B is driven to conduct excavation pipe jacking construction on thehard rock stratum by the existing low-duty power device, the required standard for the duty of the power device is reduced, thus, the municipal pipe jacking structure can be driven by the low-duty power device to conduct efficient excavation pipe jacking construction, the whole cost of the pipe jacking device during pipe jacking construction is reduced, and the pipe jacking construction efficiencyis improved.

Description

technical field [0001] The invention belongs to the field of pipe jacking, in particular to a municipal pipe jacking structure and a construction method thereof. 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. Its technical point is to correct the deviation of the pipe extending underground. It is especially suitable for trenchless laying of large and medium-sized pipes. It has comprehensive functions of economy, high efficiency and environmental protection. The advantages of this technology are: no excavation of the ground; no demolition, no damage to ground buildings; no damage to the environment; no influence on the deformation of the pipeline; time-saving, efficient, safe, and low overall cost. This technology is widely used in the non-excavation laying of various pipelines such as urban underground water supply and drainage p...

AI Technical Summary

Problems solved by technology

Considering the cost, most power devices cannot meet the requirements of large cross-section head for crushing and excavating rock formations

Generally, the drilling of the rock formation is completed by drilling a hole with a drill bit of a smaller diameter on the rock formation and reaming the hole, which is less efficient.
