Integrated Rainwater and Sewage Diversion Manhole (With Hydraulic Gate)
Product Overview
This integrated FRP rain and sewage interception manhole is a factory-prefabricated underground diversion device, equipped with an intelligent hydraulic gate, self-cleaning grating, water level and rainfall monitoring system, and automatic control system. It is widely applied in urban combined pipe network renovation, river outlet pollution remediation and sponge city projects. The device automatically separates domestic sewage and rainwater, effectively curbing river overflow pollution and enhancing urban drainage efficiency.
Core Functions - Hydraulic Gate Working Principle
1. Full Sewage Interception in Dry Weather In dry conditions, the hydraulic gate keeps the sewage interception channel open and seals the rainwater discharge passage. It fully collects domestic sewage and delivers it to treatment facilities, prohibiting untreated sewage from flowing into rivers and lakes.
2. Intelligent Rainfall Diversion In the early stage of rainfall, the gate maintains interception mode to trap polluted initial rainwater carrying surface contaminants. Once rainfall intensity reaches the preset threshold, the hydraulic gate automatically switches the flow path, allowing clean later-stage rainwater to discharge directly into water bodies and reduce the operational load of sewage treatment plants.
3. Flood Anti-backflow Protection During flood seasons with rising river water levels, the hydraulic gate closes rapidly to block backflow of river water into urban pipe networks, preventing regional waterlogging and reverse sewage overflow.
4. Automatic & Remote Intelligent Operation Powered by a professional hydraulic unit, the gate operates stably with high thrust and anti-jamming capability. It supports automatic linkage with water level and rainfall sensors as well as remote cloud monitoring and control, realizing unattended operation for outdoor pipe network facilities.
5. Superior Sealing & Anti-sediment Performance Fitted with high-quality rubber sealing strips, the gate achieves complete zero-leakage closure. Its powerful hydraulic thrust flushes away sediment and floating debris effectively, avoiding silt blockage and ensuring long-term stable operation.
Auxiliary System Functions
The built-in trash grating intercepts leaves and floating garbage to prevent pipeline blockage. The tank self-cleaning system minimizes sediment accumulation and reduces manual maintenance workload. Real-time data monitoring and fault alarm functions guarantee continuous and reliable long-term operation.
Application Scenarios
Suitable for old urban community pipe network upgrading, river drainage outlet renovation, rural and town water environment improvement, sponge city construction and municipal rain-sewage diversion projects.
