无锡轨道交通L2查桥——九里河明挖区间变形缝渗漏水浅析

Analysis of Deformation Joint Leakage Water of Zhaqiao-Jiulihe Open Excavation Section of Wuxi Rail Transit L2

针对无锡查桥到九里河明挖区间二层与一层结构处变形缝拉裂渗漏水问题,客观全面地分析结构基础、地面堆载、施工质量、外界环境变化影响等各种因素,提出静压钢管桩注浆加固结构基础、结构面层增设内置补强钢板等有效解决措施,建议类似工程在实施各阶段应及时反馈外界环境变化带来的影响,全过程动态控制。

Aiming at the problems of seepage and leakage of deformation crack in the secondstory and one-story structure of Qiliqiao to Jiulihe cut-open interval in Wuxi Rail Transit,Objective and comprehensive analysis of structural foundation,ground heap load,construction quality,the impact of external environmental changes and other factors The paper puts forward effective measures to strengthen the structural foundation of staticpressure steel pipe pile by adding grouting steel plate. It is suggested that the similar project should feedback the influence of the external environment change and the dynamic control of the whole process in every stage.
