HDD Method (Directional Horizontal Drilling) - Solving Problems of Crossing National Highways, Railways, and Waterways
Piping and wiring burial system! Numerous achievements! Solving problems of "crossing national roads, railways, waterways, and rivers"! "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 is becoming 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 drilling. In recent years, disasters have become more severe, and from the perspective of improving disaster prevention, the replacement of aging pipes and the transition to earthquake-resistant pipes are being promoted. The HDD method (Horizontal Directional Drilling) / TerraJet is gaining attention as a method for burying water supply and drainage pipes, gas pipes, electric cables, and communication lines underground. In Europe and the United States, this method is commonly referred to 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.
