摘要
山地城市地形坡度较大、地面情况较复杂,排水管道系统上、下端落差大。在设计某排水管道系统时,综合考虑了当地地势、地质条件以及周边环境,在落差为43 m的"雨、污水瀑布"处采用钢筋混凝土嵌岩式跌水箱涵的方式将该处污水截流,末端连接架空球墨铸铁管将污水排至主干管。雨季部分雨水进入箱涵及管道,大部分雨水通过溢流堰溢出。设计充分利用了"雨、污水瀑布"冲刷形成的梯级岩石,采用"嵌岩式跌水箱涵"收集污水,从根本上改善了周边环境,为相关工程提供了设计参考。
In the mountainous cities, the terrain slope is steep, the ground is relatively complex, and the drainage pipe system has big ups and downs. After the comprehensive consideration of local topography, geology conditions and the surrounding environment, the design of a drainage pipe system adopts the reinforced concrete rock-socketed drop water box culverts at the rainwater and sewage waterfall with a drop of 43 m to intercept the sewage and drain it to the trunk pipe through overhead ductile iron pipes. In the rainy season, a part of rainwater enters the box culverts and the pipeline, and most rainwater overflows through the overflow weir. The design makes full use of stair-shaped rock formed by the rainwa- ter and sewage waterfall, and the rock-socketed drop water box culverts is used to collect sewage, which can radically improve the surrounding environment and provides a reference to the relevant projects.
