HDD method (induced horizontal drilling) achieves shortened construction time and labor savings!
Piping and wiring underground installation system (non-excavation and thrust method)! Numerous achievements! Also gaining attention for "overhead line removal"! "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 that buries pipes and cables through non-excavation (non-excavation method and thrust method), reducing traffic disruption and soil disposal issues. It allows for clean and highly safe construction by detecting the construction position from above ground while advancing. In recent years, the shortage of human resources and the rising costs of facility maintenance and repairs have become social issues. From the perspective of shortening construction periods and reducing total costs, the HDD method (Horizontal Directional Drilling) / TerraJet is gaining attention as a method for burying water supply and drainage pipes, gas pipes, and power cables underground. 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.
