ダム堆積物下流還元方法およびシステム

Japanese Patent JP7089137

B2

To provide a method and a system for returning a dam deposit downstream, which does not adversely affect downstream rivers even if silt clay contained in the dam reservoir deposit is supplied downstream of the dam.SOLUTION: This method for returning a dam deposit downstream is a method for returning a dam deposit downstream that supplies deposit of a dam reservoir to the downstream of a dam, and comprises a step of classifying the deposit dredged from a reservoir 2 in a normal state into a silt clay component having a predetermined particle size or less and sand having a predetermined particle size, a step of sending the classified silt clay to a sludge reservoir 12, a step of storing and precipitating silt clay in the sludge reservoir, a step of supplying water from the reservoir to the sludge reservoir during floods, a step of stirring the precipitated silt clay to make mud water, and a step of supplying mud water downstream of the dam based on the discharge rate (m/sec) of the dam.SELECTED DRAWING: Figure 1
