Tunneling device for pipe jacking construction

Abstract

The invention discloses a tunneling device for pipe jacking construction, and relates to the technical field of geological engineering. The tunneling device comprises a front cylinder, a rear cylinder, a front wall cutting assembly and a muddy water storage bin; the side part of the front wall cutting assembly is rotatably connected with the side wall of the muddy water storage bin; the tunneling device further comprises a front sealing plate, a smashing assembly, a power assembly and a water injection and discharging mechanism; a shaft pipe body rotating on the front sealing plate is arranged on the front sealing plate, the shaft pipe body is driven by the power assembly to rotate, and a spray head is arranged at the side, away from the front cylinder, of the front wall cutting assembly and communicates with the shaft pipe body; the smashing assembly is arranged on the shaft pipe body and located in the muddy water storage bin, and the smashing assembly is used for smashing mud blocks in the muddy water storage bin when the shaft pipe body rotates; and the water injection and discharging mechanism is used for sucking slurry accumulated in the muddy water storage bin and injecting water spots into the shaft pipe body. By means of the tunneling device, the structure is simple, rotary cutting of soil on the front wall is convenient, tunneling is convenient, mud is cut up and mixed into the slurry to be discharged in time, and practicability is high.

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...
