ENERGY DISSIPATION WORKS OF SPILLWAY WATER FLOW AND ENERGY DISSIPATION METHOD

摘要

PPROBLEM TO BE SOLVED: To provide energy dissipation works capable of making energy dissipation of also force of a very fast-flowing water without making any shaft or any height difference between a spillway and a flood way. PSOLUTION: The energy dissipation works are installed in a cylindrical flood way 1 having a flood way floor surface 1a to which the flood way 2 making inflow of flowing water is connected and a flood way ceiling surface 1b, and it is equipped with a lower sill 3 installed in the flood way floor surface 1a on a down-stream side lower than a part to which the spillway 2 is connected and an upper sill 4 installed in the flood way ceiling surface 1b in a pushed up domain 10 within a range reaching the flowing water clashing with the lower sill 3 to the flood way ceiling surface 1b.
