淤泥质地基基坑应急加固施工方法

Construction Method of Emergency Reinforcement of Foundation Pit on Muddy Foundation

为解决因地勘报告不准确淤泥质地基基坑施工过程中存在较大安全隐患的问题,在保持原基坑围护设计的基础上,采取增加水泥加固土桩、优化柱下墩施工工艺和采用新型高分子卷材加快底板结构等方法,增强淤泥质地基基坑安全稳定性。

To solve the problem of geological exploration report inaccurate muddy the larger potential safety hazard in foundation pit construction process problems,while maintaining the original pit supporting design,on the basis of increase cement soil pile,optimization of column pier construction technology and the methods of new type polymer coil to speed up the floor structure,enhance sludge quality,and the stability of foundation pit safety.
