HDD method (induction horizontal drilling method) TerraJet method - compatible with overhead wire elimination.
Piping and wiring burial system (non-excavation method, thrust method)! Attention on "overhead line removal"! "Challenging the creation of lifelines that run through 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 the surface while advancing. In recent years, with the increasing severity of disasters, the promotion of underground power lines and communication lines has been emphasized from the perspective of improving disaster prevention, and the HDD method / TerraJet has gained attention as a method for this purpose. In Europe and the United States, it is known by names such 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.
