开挖深度工程中的雨污分流管道支护施工技术研究

Research on supporting construction technology of rain and sewage diversion pipeline in excavation depth engineering

本文以德州开发区雨污分流工程为研究对象,分析压力流径流过程曲线,计算雨污分流工程管道流量,确定出不同开挖深度对雨污分流工程管道影响的支护结构极限状态。根据支护结构,构建支护结构的工作状态,设计雨污分流工程管道支护施工流程,对槽钢支护和内支撑支护施工应用实例进行分析,在工程管道施工中防止安全事故发生。

Taking the rainwater and sewage diversion project in Dezhou development zone as the research object, the pressu re f low r unoff process line is analyzed, the pipeline flow of the rainwater and sewage diversion project is calculated, and the limit state of the support structure of the influence of different excavation depths on the rainwater and sewage diversion project pipeline is determined. According to the support structure, construct the working state of the support structure, design the pipeline support construction process of the rain and sewage diversion project, analyze the application examples of the channel steel support and the inner support support construction, and prevent the occurrence of safety accidents in the engineering pipeline construction.
