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.

Abstract

The invention belongs to the field of pipe jacking, and in particular relates to a municipal pipe jacking structure and its construction method, which includes a cylinder, a knife seat A, a knife head, a knife seat B and a power device, etc., wherein a circular fixing plate is installed in the cylinder A, A shaft A rotates in the shaft slot A at the center of the fixed plate A, and the shaft A is driven and rotated by the power device installed in the cylinder; the drill bit drills the working face of the harder rock formation and further reams the drilled hole Knocking and crushing make the cutter head on the tool holder A and the cutter holder B drive the existing smaller power power device to carry out excavation and pipe jacking construction on the harder rock formation, which reduces the power requirement standard for the power device and makes The invention can carry out high-efficiency excavation pipe jacking construction under the drive of a relatively small power power device, reduces the overall cost of the pipe jacking device in pipe jacking construction, and improves the efficiency of pipe jacking construction.

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...
