徐州市某基坑渗漏处理实践

Leakage treatment technology for a foundation pit engi-neering of Xuzhou city

以徐州市某基坑渗漏处理为例,详细论述了该基坑出现渗漏的原因,采用了内侧堵漏、内侧疏水减压加外侧双液注浆、改善坡顶排水条件、增加降水措施进行堵漏处理,其中关键点是双液注浆封堵修补止水帷幕,可以为类似工程提供参考。

Taking the leakage treatment of a foundation pit in Xuzhou City as an example,the reasons for the leakage of the foundation pit are discussed in detail.The internal leakage stoppage,internal drainage decompression and external double-fluid grouting,improving the drainage conditions on the slope top,and increasing precipitation measures are adopted for the leakage stoppage treatment.The key point is the double-fluid grouting sealing and repairing the water stop curtain,which can provide a reference for similar projects.
