The pre-treatment device pre-treats the water to remove floating matters from the water.
Abstract:
PURPOSE: A closed conduit structure for rainwater is provided to ensure easy cleaning and management of rainwater pipelines because most of foreign materials are accumulated in a sedimentation tank installed directly under a rainwater inflow path. CONSTITUTION: A closed conduit structure for rainwater comprises a sedimentation tank(210), an over flow part, a pipeline body(200), a cover(110), and a filter channel(100). The sedimentation tank is recessed in order to provide a space in which foreign materials included in initial rainwater are deposited and accumulated. The over flow part is formed on the top of a side of the sedimentation tank and allows rainwater flowing from the sedimentation tank to flow over a sidewall(130). The pipeline body comprises a waterway through which the rainwater flowing over the over flow part moves to the destination. The cover is exposed on the ground and has an inlet hole(112) to let rainwater flow in. The filter channel forms a rainwater inlet path(140) for conducting rainwater flowing from the ground to the laid sedimentation tank of the pipeline body.
