Pit-pond water outlet structure of water conservancy project
The invention is suitable for the field of water conservancy projects, and provides a water conservancy project pit-pond water outlet structure which comprises a water outlet pond, a grate type filter screen is arranged in the water outlet pond, a water conveying pipeline is connected to the water outlet pond, one end of the water conveying pipeline is connected with a steel pipe through a flange, and a gate valve is connected to the steel pipe; the gate valve is connected to the interior of the stilling pool; the maintenance steps are arranged on the two sides of the dam body, and the water outlet pool and the stilling pool are arranged on the two sides of the maintenance steps. According to the water outlet structure, the PE pipeline and the pond dam outer slope gate valve are adopted for control, the integral hot melting connection PE pipeline is good in leakproofness and high in pressure bearing capacity, and the PE pipeline is made of a flexible material, is tightly combined with a soil pond ridge and is good in stability, and the problems of settlement, seepage and the like of a dam body cannot be caused; secondly, the problem of water leakage of an original flap valve is avoided by canceling a graded flap valve and adopting a control mode of a gate valve at the tail end of a PE pipeline; and thirdly, overhauling steps are arranged on the back slope of the pond ridge, underwater operation is avoided, and overhauling and maintenance of the water outlet are facilitated.
本发明适用于水利工程领域，提供了一种水利工程的坑塘出水结构，包括：出水池，出水池中设置有篦子式过滤网，出水池上连接有输水管道，输水管道一端通过法兰连接有钢管，钢管上连接有闸阀；消力池，闸阀连接在消力池内部；检修踏步，设置于坝体两侧，且出水池和消力池设于检修踏步两侧。该出水结构采用了PE管道和塘坝外坡闸阀控制，一体性热熔连接PE管道密闭性好，承压能力强，且PE管道为柔性材质，与土质塘埂结合较为紧密，稳定性好，不会造成坝体沉降和渗流等问题；二是通过取消分级拍门，采用PE管道末端闸阀控制的方式避免了原有拍门漏水的问题；三是在塘埂背坡设置检修踏步，避免水下作业，更有利于出水口检修和维护。
