The Shin Maruyama Dam Construction Project is a dam regeneration project that raises the function by raising the height by 20.2 m at a location 47.5 m downstream of the existing Maruyama Dam located in the middle part of the Kisogawa Honkawa.
In large rivers such as the Kiso River, raising a large-scale dam while maintaining the functions of the Maruyama Dam is a pioneering dam construction in terms of design and construction methods.
The purpose of this report is to minimize the impact of gate discharge from the Maruyama Dam during the construction of the Shin Maruyama Dam and report on the construction plan for safe construction.
