德厚水库引水隧洞塔式进水口分层取水设计

Stratified Water Intake Design for Water Diversion Tunnel Tower Water Inlet in Dehou Reservoir

为实现取用水库表层优质水,减轻下泄深层低温水对人畜饮水安全及农作物生长和下游水生生态环境产生不利影响,德厚水库采用"平面重合、立面分层、一电多控"的平面钢闸门分层取水。各取水口在平面布置上重合,立面分设于进水塔不同高程,多扇取水闸门共用一个门槽和一套启闭设备。该方案具有结构布置简单、土建及金属结构工程量小、工程投资少,运行操作及养护维修简单方便等优点,可供类似工程设计借鉴。

Plane steel gate stratified water intake of‘plane superposition,elevation stratification and multi-control for one power supply＇is adopted in Dehou Reservoir in order to access of reservoir surface high-quality water,and reduce the adverse influence of discharge deep low temperature water on human and animal drinking water safety,crop growth and downstream aquatic ecological environment. All water intakes are superposed in plane layout. The elevation is respectively set at different elevation of the water intake tower. Many water intake gates share one gate slot and one set of hoisting equipment. The plan has the advantages of simple structure layout, small civil construction and metal structure engineering,little engineering investment,easy operation and maintenance,etc.,and it can provide design reference for similar projects.
