Description

1. Technical field [0001] The invention relates to a non-excavating underground pipeline cave wall expansion propulsion machine, which belongs to the field of engineering machinery. 2. Background technology [0002] At present, the underground pipeline projects in many cities in my country still use the traditional excavation method, and many new technologies are put on the shelf due to high construction costs, technical difficulties, and expensive equipment. Such as: spiral horizontal drilling machine, which is composed of several main parts such as machine base, gearbox, motor, drilling head, auger rod, hydraulic thrust device, and anchoring facilities. [0003] When working, put the main engine into the working pit, fix it on the anchoring facility made of concrete, find a good balance, the motor drives the screw rod and the rotor to rotate in the soil layer through the gearbox, and the hydraulic cylinder pushes the ejector rod to drill forward and follow As the drilling...

AI Technical Summary

Problems solved by technology

[0006] (3) The construction preparation workload is heavy and the time is long

[0007] (4) The equipment is complicated, the process is complicated, and it is not easy to operate

[0008] (5) Expensive equipment and high construction costs

[0009] Due to these shortcomings, its competitiveness in terms of economy, adaptability, and popularity in the construction of trenchless underground pipelines is obviously insufficient.
