奎河截污管工程中轨道交通保护施工方案探讨

Discussion on Construction Scheme for Rail Transit Protection in Kuihe Sewage Intercepting Pipe Project

摘要:

城市新建市政管道工程可能对临近的轨道交通隧道结构的安全运行产生影响。徐州市区奎河综合整治工程截污主干管工程建国西路～建国东路段上跨轨道交通地铁2#线盾构隧道，截污管管底距地铁盾构顶竖向净距最小仅6.1 m。依托该工程，总结介绍了顶管工程中针对轨道交通保护的工程施工安全质量保证措施及应急预案，旨在为类似工程提供借鉴和参考。

Abstract:

The construction of new municipal pipelines in cities may cause an impact on the safe operation of adjacent rail transit tunnel structures. The section of West Jianguo Road - East Jianguo in Kuihe Comprehensive Treatment Project in the urban area of Xuzhou spans the shield tunnel of Metro Line 2. The minimum vertical clear distance from the bottom of the sewage intercepting pipe to the top of the subway shield is only 6.1 m. Relying on this project, the assurance measures and contingency plans for the engineering construction safety quality aiming at the rail transit protection in pipe jacking engineering are summarized and introduced, which is aimed of providing for the similar projects.
