西安市南三环地区排水系统规划的探析

排水管网规划在排水工程建设中的作用是举足轻重的,在结合现状管网情况下进行城市的排水工程规划,充分利用现状管网是整个工程建设中节约成本,避免重复投资的重要环节。雨水管道系统依据地势地形特征,以及河流水系分布情况,按照分散布局和就近接入南三环雨水主干管,集中排放的原则规划布置,充分利用和改造现有雨水设施,积极扩建和新建新的雨水设施。污水管道系统采用平行式的排水系统布置方式,有效地控制了各个路段干管的埋深,不考虑设置提升泵站,将污水截流,实现雨污分流,以保护环境。

The Exploration of Drainage System in the Area of South Tricyclic of Xi'an

The paper shows that the very important function of drainage pipe network in drainage project constructions,exposits concretely that how to plan the city drainage project under the existing pipe condition and stands out the using existing pipe is the key link on cost saving and overlapping investment avoiding with in the all project constructions.Storm Sewer System based on terrain features and the distribution of river water,according to the distribution and the nearest switch-on south tricyclic main rain pipe and a main focus of the principle of emissions planning layout,and make full use of rainwater and upgrading existing facilities and building new water facilities with active extension.Sewage pipes adopt parallel layout of the drainage system,in order to effective control of the depth of all the sections of the trunk without considering installing liftpump station,cutting of the sewage and parting the rain and sewage,to protect the environment.
