Pipe jacking construction is one of the underground pipeline trenchless construction methods. It does not need to excavation and be able to cross roads. Railways, rivers, ground buildings, underground structures, and all kinds of underground pipeline, etc

Pipe jacking construction is in the work well with the help of the jacking device to produce thrust, overcome the friction of the soil and around pipeline, the pipeline according to the direction of the design in the grave, and will abandon soil by pipe jacking knife dish for positive soil cutting whole section, through the mud pump and spiral lose soil machine and away from other ways. After the first quarter tube to complete entering into soil layer, and then the second section continues into the pipe, in turn, continuous operation, its principle is by means of the main oil cylinder thrust, the tools pipe and machine from work shaft through the soil has been advancing to receive in the receive shaft and hung, pipe with tools pipe and machine, lay buried in between two shafts. It suits for various soil conditions like sandy soil, clay, soft soil, to hard soil and weathered rock, etc. The construction precisoin is very high and can do the long distance excavation.

The company persists in the principle of Quality First and Clients Supreme all along and provide clients with high-quality products, considerate after-sales services and true management ideas.

We will provide excellent machines and good service to you.
