Piping and wiring burial system! Numerous achievements! Capable of handling conditions that are "difficult to construct using open-cut methods"! "Challenging the creation of lifelines that traverse the Earth and underground."
With the acceleration and advancement of urban functions, the development of various lifelines such as water supply and drainage, electricity, gas, and communication has become increasingly important. The HDD method (Horizontal Directional Drilling) / TerraJet is a construction method for burying pipes and cables using non-excavation techniques, which reduces traffic disruption and soil disposal issues. It allows for clean and safe construction by detecting the construction position from above ground while advancing. In recent years, there has been a demand for consideration of neighboring residents and responses to traffic congestion, leading to the HDD method / TerraJet gaining attention as a technique for burying water supply and drainage pipes, gas pipes, and electric cables underground under conditions where traditional excavation methods are difficult. In Europe and the United States, this method is known as NO-DIG, Trenchless, HDD (Horizontal Directional Drilling), No-Dig, Trenchless, and Horizontal Directional Drilling. 【Features】 - Flexibility and adaptability - Shortened construction period - Economically low cost - Harmony with the natural environment - Safety For more details, please contact us or download the catalog.
