地下地铁车站作为地下结构,防水性能是其实现使用功能的重要指标。变形缝是由于考虑结构不均匀受力和混凝土结构胀缩而设置的允许变形的结构缝隙,它是防水处理的难点,也是结构防水中的关键环节。对于变形缝的渗漏水处理,施工单位要结合现场的渗漏情况及整治材料性能,拟定整治方案。本文通过对明挖地铁车站中因混凝土质量原因存在渗漏水变形缝的整治过程,详细介绍整治方案。
Underground metro station as an underground structure, waterproof performance is an important indicator of its use function. Deformation crack is due to uneven structure and concrete structure expansion and contraction of the set allowable deformation of the structural gap, it is waterproof processing difficulties, but also the key to structural waterproofing. For the deformation of the seam leakage of water treatment, the construction unit should be combined with site leakage and remediation materials performance, develop remediation program. In this paper, because of the quality of concrete in the digging metro station there is leakage of water deformation of the seam remediation process, detail the remediation program.
