随着首都市政排水设施的扩建我市政处一所在南护城河沿岸下水道出口上试建了利用河水浮力和管道水位压力作用而启、闭的闸门。这种闸门经过几年来汛期使用的考验能做到平时下水道清水,污水分流,雨时及时排洪的效果。现将我所用“自动闸门”代替原“手摇式闸门”情况作简要的介绍; 一、下水道出口闸门的改建是一项雨,污分流兼顾防汛排洪的重要措施。解放以来,首都的市政建设迅速发展,
With the expansion of the city’s municipal drainage facilities, the Municipal Office has built a gate that opens and closes by using the pressure of the buoyancy of the river and the pressure of the pipeline water level on the exit of the sewer along the south moat. After several years of flooding, this type of gate can be used to clear the water in the sewer, divert the sewage, and discharge the rain in time. Now I will use the “automatic gate” instead of the original “hand-operated gate” situation for a brief introduction; First, the reconstruction of the sewer exit gate is a rain, sewage diversion to take into account the important measures of flood control flood discharge. Since the liberation, the municipal construction of the capital has developed rapidly.
