Three Points for Attention when Using HDD Machine for Pipe Pulling Construction

Pipe pulling is a trenchless technology involving expertise in geotechnical, surveying and HDD Machine. Tubing construction should be jointly managed by a technical team composed of geotechnical, surveying, and mechanical professionals. The technical team conducted detailed itemized analysis of the overall system composed of geological environment and mechanical equipment, starting with the details and formulating a finer tube drawing plan. In the process of the HDD machine, the technical personnel strictly carry out the operation and construction in accordance with the operation specifications and the degree of control to achieve success.

Attention should be paid to the use of HDD Machine for tube construction:

1. When the HDD Machine travels, it transmits longitudinal force between the tubes;
2. Transmit lateral force when the pipeline direction changes;
3. Sealing between tubes.
