摘要
本文以湘江永州至衡阳三级航道建设三期工程-潇湘船闸工程为例,采用帷幕灌浆与高压旋喷相结合的施工方案,在上下游横向围堰和江心岛宋家洲侧的纵向围堰构筑了防渗工程,详细介绍了此防渗工法建造防渗墙的施工工艺、施工顺序和施工方法,并对在施工过程中常遇到的问题给出了切实有效的处置方案,并在施工过程中严格执行既定标准,为该项技术在类似工程中的应用提供了参考。
Taking the third phase of the Xiangjiang River Yongzhou to Hengyang three-level navigation construction project-the Xiaoxiang Shiplock Project as an example,this paper adopts a construction plan combining curtain grouting and high-pressure jet grouting to build a waterproofing project in the upstream and downstream transverse cofferdams and the longitudinal cofferdam on the side of Songjiazhou Island in the river.The construction technology,sequence,and methods of building the waterproofing wall using this waterproofing method are introduced in detail.Practical and effective solutions are provided for common problems encountered during construction,and strict adherence to established standards during construction is emphasized.This provides a reference for the application of this technology in similar projects.
