Non excavation industry as a high-tech industry, commonly used several new trenchless technology: Horizontal Directional Drilling, pipe bursting, microtunneling, pipe jacking, auger boring. We also has Trenchless Machinery with high quality.
The horizontal directional drilling method has a construction length of 15-1800meters, and a diameter of 25-1200 millimeters. It is mainly used in municipal engineering, pipeline facilities, sewer pipes, pressure pipes and other construction. Micro tunnel method is mainly used in the installation of sewers, construction length of 25-225 meters, diameter of 250-3050 mm. Pipe jacking method is mainly used in large scale sewer and pressure pipeline installation, the construction of up to 490 meters in length, diameter 1060-3050mm.
