Comment

This is a specific multipurpose dam constructed for flood control and water utilization in the downstream of the Kinugawa River and Tonegawa River in Tochigi Prefecture. It is a concrete gravity dam with a height of 119 m. Due to the construction delays caused by the Great East Japan Earthquake, further shortening of the project timeline was strongly desired. Consequently, the adoption of the specific lift cruising RCD method significantly improved construction efficiency, resulting in a record-setting construction period of just 19 months—one of the most notable achievements in Japan. Following this, we also conducted the slope protection work.
