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 safe construction by detecting the installation position from the surface while advancing in a curved direction both vertically and horizontally. Additionally, since traditional shaft construction is not required and a "simple shaft" suffices, construction periods can be shortened, leading to reduced total costs. In recent years, as disasters have become more severe and lifelines have aged, the renewal and seismic retrofitting 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, 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.
