Slope Protection Work at the Yunishikawa Dam

(12/2008～3/2012)

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 impact of the suspension of construction caused by the Great East Japan Earthquake, there was a desire for further shortening of the construction period. Consequently, the adoption of the specific lift cruising RCD method has led to increased efficiency, resulting in a record shortest construction time of 19 months, which is one of the most notable achievements in Japan. Following this, our company also conducted slope protection work.
