Infrastructure

Dam / Highway / Tunnel

Essential to our daily lives, infrastructure represents industry’s backbone. A country’s future depends on the soundness of its infrastructure.

Drawing on proprietary technologies, we’re contributing to improvements in transport facilities, such as roads, railways, airports, and sea ports; waterworks, sewerage systems, rivers, and other facilities for daily life; energy generating facilities; and communications facilities.

Helping daily life with our technologies

Construction of the main structure of the Oitagawa Dam (phase 1 and phase 2)

The Oitagawa Dam is a rockfill dam with a height of 91.6 m, located on Nanasegawa River of the Oitagawa River system. It is a multipurpose dam to ensure flood control, keep the normal functions of flowing water, and take water for water supply. We carried out foundation work and slop protection work.

Tokyo-Gaikan Expressway has been constructed to reduce traffic congestion between Koyama in Matsudo City and Koya in Ichikawa City in Chiba Prefecture. Along the route, the Kokubun works and the Ichikawa-naka works require underground improvement and construction of surrounding environmental facilities. Our Jet Grouting and Chemical Grouting were used for these works.
