深厚淤泥质河床管廊过河双钢板桩围堰施工技术研究

Study on Double Steel Sheet Pile Cofferdam Construction Technology of Utility Tunnel Crossing Deep Silty Riverbed

综合管廊是今后大力发展的地下市政工程布局,而现浇法是最主要的一种施工形式。以嘉兴科技城项目为例,对深厚淤泥质河床管廊过河双钢板桩围堰施工技术进行探讨,从围堰结构设计、淤泥质河床基底注浆处理和围堰内壁掺灰土填芯技术进行了详细分析,可为类似工程提供参考。

The utility tunnel is the underground municipal engineering layout energetically to develop in the future,and the cast-in-site process is the most main construction form.Taking the Jiaxing Technology City Project as an example,the article discusses the double steel sheet pile cofferdam construction technology of utility tunnel crossing deep silty riverbed,and analyzes the cofferdam structure design,the silty riverbed base grouting treatment and the cofferdam inwall lime-added soil filling core technique in detail,which can be referred for the similar projects.
