摘要：To control the overflow and water level of hydraulic structures, in particular inrainwater-storage and rainwater-treatment installations, storm-water tanks and sewage-clarification plants, the rain-overflow retaining plate is installed as a control device. Theretaining plate (21) is connected to a counterweight (22) of hydraulic shape (27) viatackles (66, 65, 68) and is equipped, for lateral guidance, with guiding bars (55), alsoreferred to as side pieces, and roller-guiding elements (58). When the given water level(N2) is exceeded and consequently the closing force applied by the counterweight (22) isexceeded, the retaining plate (21) opens as a result of the sill (28) moving back, and theoverflow water (30) flows between the bottom edge (32) of the retaining plate and thesill (28) and through the overflow space (36) to the receiving water. The retaining plate(21) is also designed as a backflow-preventing device.
