Abstract

The invention discloses a tunneling device for pipe jacking construction, which relates to the technical field of geological engineering. The tunneling device includes a front cylinder body, a rear cylinder body, a front wall cutting assembly and a muddy water storage bin. The side wall of the warehouse is connected by rotation; it also includes the front sealing plate, the crushing assembly, the power assembly and the water injection and discharging mechanism; The side of the cutting assembly far away from the front cylinder is provided with a nozzle and the nozzle is connected to the shaft body; the crushing assembly is arranged on the shaft body and is located inside the muddy water storage bin, and the crushing assembly is used for when the shaft body rotates Crush the mud in the muddy water storage bin; the water injection and discharge group mechanism is used to absorb the mud accumulated in the muddy water storage bin and inject water stains into the shaft tube body. The invention has a simple structure, and the front wall rotary cuts the soil conveniently, which is convenient for excavation, and the mud material is chopped and mixed into mud and discharged in time, so the utility model has strong practicability.

Description

technical field [0001] The invention relates to the technical field of geological engineering, in particular to a tunneling device for pipe jacking construction. Background technique [0002] Pipe jacking construction is a pipeline burying construction technology that adopts no-excavation or less-excavation technology. Its specific operation is: in the working pit with the help of the jacking force generated by the jacking equipment, overcome the friction between the pipeline and the surrounding soil, and place the pipeline according to the design. The slope is pushed into the soil and the earth is transported away. [0003] During the construction of the pipe jacking construction, the excavation device is inserted into the convex, and the soil debris formed after the existing excavation device is broken is different in size, and it is difficult to discharge it when it accumulates in the cabin, which leads to the failure of the pipe jacking equipment during the working proce...
