The independently developed full-hydraulic pushing and pulling pipe machines with diameters ranging from DN300 to DN800, the THD-300 trenchless horizontal directional drilling rig and its supporting equipment have the advantages of high directional accuracy, large pushing force, fast propulsion speed, and high efficiency with energy conservation. They can meet the construction requirements for pipe jacking of various pipes such as glass fiber reinforced plastic sand-filled pipes, concrete pipes, polyester pipes, steel pipes, and PE pipes used in municipal water supply and drainage.

Advantages

The equipment occupies less site area and does not pollute the environment. It is an efficient tool for urban municipal micro-pipe jacking construction and has been widely applied to the construction of new pipelines and the restoration of old pipelines in the fields of water supply, drainage, electricity, communication, gas, etc.
