MULTI POINT SEDIMENT FLUSHING TYPE RUBBER DAM

摘要

PURPOSE: A multi-point sediment flushing type rubber dam is provided to increase the area of removing a sediment layer through multi-point flushing of sediment. CONSTITUTION: A multi-point sediment flushing type rubber dam comprises a rubber body(10), a body mounting plate(30), a branch pipe(40), and inlet pipes(50). The rubber body is expanded and contracted according to the injection and exhaustion of compressed air. The body mounting plate, on which the body is installed, is fixed to the river bed. The branch pipe is laid under the body mounting plate and arranged in the longitudinal direction of the river, with an outlet exposed to the downstream side of the body. The inlet pipes connect the upper side of the body mounting plate to the branch pipe. Sediments and sludge accumulated directly above the body are discharged through the inlet pipes and the branch pipe to the downstream side of the rubber dam.
