Innovative construction method! HDD method (Guided Horizontal Drilling) TerraJet

Piping and wiring embedding 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 communication is becoming increasingly important. The HDD method (Horizontal Directional Drilling) / TerraJet is a construction method that allows for the installation of pipes and cables without excavation, reducing traffic disruption and soil disposal issues. It enables clean and highly safe construction by detecting the construction position from the surface and advancing in an arc direction both horizontally and vertically. Additionally, it eliminates the need for traditional shaft construction, allowing for a simplified shaft, which shortens the construction period and reduces total costs. In recent years, disasters have become more severe, and as lifelines age, the renewal and seismic retrofitting 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, electric cables, and communication lines underground. 【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.
