HDD工法（誘導式水平ドリル工法）テラ・ジェット協会 Company Profile

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 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 installation 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 simplified shafts, which shortens construction time and reduces total costs. In recent years, as disasters have become more severe and lifelines have aged, the renewal and seismic reinforcement of aging pipes have been promoted from the perspective of improving disaster resilience. The HDD method / TerraJet is gaining attention as a technique for burying water supply and drainage pipes, gas pipes, electrical 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.
