上海市白龙港片区污水输送总管施工方案分析

Project Analysis of Sewer Trunk Construction Scheme at Shanghai Bailonggang

上海市白龙港片区南线东段污水输送干管为特大型输送干线工程.鉴于传统大开挖施工方法在该工程施工中的局限性,分别提出了顶管法、盾构法和箱涵开挖法方案,并对这3种施工方案进行了多角度的综合对比与分析.结果表明,顶管施工法具有综合造价低、施工周期短、安全性能高和社会效益好等优势,是该工程的最优施工方案.

Shanghai Bailonggang sewer trunk project is an extra large project.For limits of the traditional construction method,the pipe jacking construction method,the shield construction method and the box culvert construction method were presented,and advantages and shortcomings of each method were analyzed.The result shows that the pipe jacking construction method with advantages of low cost,short construction period,excellent safety performance and good social benefits is the optimum construction method for this project.
