摘　　要：以某市的城区排水系统为例,探究了雨污分流改造技术的应用。在保留合流管道的基础上修建截流干管,并利用溢流井、沉淀池等设施削弱溢流污水对环境的影响。结合各小区排水系统现状,灵活选择“内合外分”或“内合外合”排水系统改造方案,并对小区排水立管进行改造达到了雨污分流目的。在改造中使用了夹砂玻璃钢管这类新型管材,相比于传统混凝土管具有强度大、耐老化、耐腐蚀、防渗漏等优势。在雨污分流改造中使用了水平定向钻进非开挖技术,在完成改造任务的同时最大程度上降低对地面交通的影响,兼顾了社会效益和经济效益。Taking the urban drainage system of a certain city as an example,this paper explores the application of rainwater and sewage diversion transformation technology.On the basis of retaining the merging pipeline,construct a intercepting main pipe and use facilities such as overflow wells and sedimentation tanks to weaken the impact of overflow sewage on the environment.Based on the current situation of the drainage system in each community,flexible selection of"internal integration and external separation"or"internal integration and external integration"drainage system renovation plans was made,and the drainage riser in the community was renovated to achieve the goal of separating rainwater and sewage.In the renovation,new types of pipes such as sand filled fiberglass pipes were used,which have advantages over traditional concrete pipes in terms of strength,aging resistance,corrosion resistance,and leakage prevention.Horizontal directional drilling without excavation technology was used in the rainwater and sewage diversion renovation,which not only completed the renovation task but also minimized the impact on ground transportation to the greatest extent possible,balancing social and economic benefits.
