         Trenchless Directional Drilling is new a new technology that can lay pipeline without excavation. The drilling process is driven by hydraulic, drill pipe and controlled by three specially designed drill bit to achieve straight lines and curves drilling. It can control the drilling direction and avoid underground obstacles. It also can drill up to a few hundred meters, a few kilometers. Maximum diameter can be more than 2 meters. Particularly suitable for crossing rivers, mountains, railroads, highways, and all domestic oil pipelines, gas pipelines, water pipelines, sewage pipes, power cables, telecommunications cables and other utility pipelines, laying of underground pipe network. It is not only suitable for Polymer pipe-laying, but also laying steel pipe. It can be applied in various ranges of constructions with high speed. It does not destroy the ground, do not pollute the environment, does not affect the view. Because of its unique technologies and environmental advantages, the Western countries have generally adopted. China is rapidly expanded.
