Innovative construction method! HDD method (Horizontal Directional Drilling) TerraJet
HDD method (induced horizontal drilling method) / TerraJet
Piping and wiring burial system! Avoid obstacles with vertical and horizontal curves! Reduce total costs! "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 communications is becoming increasingly important. The HDD method (Horizontal Directional Drilling) / TerraJet is a construction method for burying pipes and cables without excavation, which reduces traffic disruption and soil disposal issues. It allows for clean and highly safe construction by detecting the construction position from above ground and pushing in an arc direction both vertically and horizontally. Additionally, it eliminates the need for traditional shaft construction, allowing for simpler shafts, which shortens construction time and reduces total costs. In recent years, disasters have become more severe, and as lifelines age, the renewal and seismic reinforcement of aging pipes are being promoted from the perspective of improving disaster resilience. The HDD method (Horizontal Directional Drilling) / TerraJet is gaining attention as a method for burying water supply and drainage pipes, gas pipes, power cables, and communication lines underground. 【Features】 - Flexibility and adaptability - Shortened construction period - Economical low cost - Harmony with the natural environment - Safety For more details, please contact us or download the catalog.
