DEBRIS BARRIER HAVING ECO-FRIENDLY STEP-TYPE WATERWAY

摘要

PURPOSE: An environment-friendly stepped debris barrier is provided to prevent partial erosion of waterway by evenly controlling a water flowing speed of river. CONSTITUTION: An environment-friendly stepped debris barrier comprises a dam shoulder(10) and a waterproof path(20). The dam shoulder digs up the ground surface. The waterproof path is formed between the dam shoulders. The waterway is downwardly formed in the downstream of the waterproof path. A plurality of bed-sill works is stepped on the floor side of waterway. A steep incline part and a gentle incline part are formed on the bed-sill work in the downward direction. A fishway connected with the floor side of waterway is formed on the gentle incline part. The waterproof path is installed on the height which is in accord with the ground surface.
