某富水地区住宅地下室外墙渗漏原因分析及处理

Analysis and Treatment of Leakage of Exterior Wall about Residential Basement on a Rich Water Area

地下室渗漏是富水地区住宅工程常见的质量通病,渗漏、返潮严重影响建筑使用功能。某富水地区住宅地下室反复出现渗漏、返潮现象,通过施工资料查验、红外热像检测、混凝土内部缺陷检测、局部破损等方法进行全面检测和原因诊断,得出主要渗漏原因为柔性卷材防水层失效、局部混凝土不密实、干缩开裂及对拉螺杆洞部位施工处理不到位。进一步通过聚氨酯注浆、明挖防水层修复、结构灌缝胶注浆等组合处理方式彻底解决渗漏问题,通过内涂异丁基三乙氧基硅烷进行返潮防霉处理。相关处理措施为类似渗漏、返潮问题的解决提供了参考方案。

Basement leakage of civil buildings is a common quality fault in water-rich areas,which seriously affects the use function.A rich water area basement repeated leakage phenomenon,through the excavation inspection,local damage validation,infrared thermal image detection,concrete internal defect detection method,according to the test results and field survey,analyzes the main cause of the basement leakage,further through grouting,excavation repair,broken wall grouting and bentonite plugging treatment completely solve the problem of leakage.Relevant treatment measures provide a reference scheme for the solution of similar leakage problems.
