LOW HEAD BAR SCREEN WATER INTAKE WORK AND CONTINUOUS FLOW TYPE CASCADE WORK HAVING THIS WORK

摘要

PPROBLEM TO BE SOLVED: To provide a low head bar screen water intake work capable of largely shallowing the depth of a catchment passage downstream end more than a conventional depth, and to provide a continuous flow type cascade work having at least one low head bar screen water intake work, and further easily adaptable to a river environment. PSOLUTION: This bar screen water intake work has a slope having the step height of a specific height for making surface water flow down in the vicinity of the center in at least the flowing direction, is provided with a water intake part for arranging a bar screen on the slope, and collects water to an inside catchment passage from the water intake part. The continuous flow type cascade work has the water intake work in at least one place. An upstream side wall surface lower part of the catchment passage has particularly a circular opening flume.
