NET PLACE FOR INTAKE OF RIVER

摘要

PROBLEM TO BE SOLVED: To remove a large-size trash caught in a net place spread on an intake for a river. SOLUTION: A net place 3 whose front face side and upstream side only are blocked and whose downstream side is opened to use it as a water take-in port 4 for an intake 2 opened orthogonally for a stream of a main stream 1 of a river is used. This net place 3 is spread out by a pair of arms 12, 12 up to a position where cleaning force due to the main stream 1 is obtained to repel a large-sized trash from the net place 3 and flow it on a river surface side so as to dispense with the work for cleaning the large-sized trash.
