Problems solved by technology

[0002] The existing underground construction method is generally to dig the entire ground with an excavator, and then the personnel go down to the ground for construction, and this kind of construction requires a lot of manpower, takes a long time, occupies a large space, and is very unfavorable compared to transportation
At present, many cities have switched to digging wells at the starting point and the end, and then directly constructing at the bottom of the well. This construction method requires relatively little manpower and material resources, and has little impact on transportation.
However, there are still many problems in the prior art of this construction method: high labor intensity, long construction time, and can only solve the construction problem of soft soil layer. At the same time, the direction of pipe jacking is prone to deviation during construction. Construction quality will have a serious impact

Abstract

The invention provides a split type spiral pipe jacking machine. An adjusting base is arranged under a main engine. An operating table is arranged on the main engine. A power head device is arranged in the center of the main engine. A water injection device is connected with a slurry pump through a water pipe. Oil cylinders are arranged on the two sides of the power head device correspondingly. The oil cylinders are connected with a power station through oil pipes. A laser theodolite is erected behind the power head device. A light target is arranged inside a guide head. The laser theodolite, the light target and a laser receiving device are all connected with a computer monitor. The invention further provides a construction process by means of the spiral pipe jacking machine, the process can be suitable for construction for various complex soil layers, the labor intensity is relieved, and the construction efficiency is improved; and compared with an existing machine head driven by a hydraulic motor, a machine head of the split type spiral pipe jacking machine has the advantages of being large in achieved torque, high in jacking speed and the like.

Description

technical field [0001] The invention belongs to the construction field of non-excavation mud discharge pipelines, and in particular relates to a split-type screw pipe jacking machine and a construction process thereof. Background technique [0002] The existing underground construction method is generally to dig the whole ground with an excavator, and then the personnel go down to the ground for construction, and this kind of construction requires a lot of manpower, takes a long time and occupies a large space, which is very unfavorable compared with transportation. At present, in many cities, wells are dug at the starting point and at the end, and then construction is carried out directly at the bottom of the well. This construction method requires relatively little manpower and material resources, and has little impact on transportation. However, there are still many problems in the prior art of this construction method: high labor intensity, long construction time, and ca...
