地连墙渗漏原因分析及处理措施浅谈

Causes Analysis on Diaphragm Walls and Discussion on Treatment Measures

地下连续墙具有抗渗、挡土和承重功能,是基坑工程中最佳支护结构之一。但由于施工工艺和施工过程中诸多不确定性因素导致地下连续墙质量方面存在缺陷,在基坑开挖过程中产生渗漏水,严重时出现涌水、涌砂,基坑周围地面产生不均匀沉降,基坑开挖无法进行,加大基坑工程的风险,造成较大的损失和浪费。

Diaphragm,which is one of the best support structures,has functions of impermeability,soil retaining and load-bearing.However,many uncertain factors in the construction technology and construction process causes quality defects in diaphragm wall,in the excavation process,there is leakage of water,even a serious water burst,sand burst,uneven ground settlement around foundation,causing excavation stops and the risk of excavation increases,resulting in large losses and waste.
