狭窄空间超深地下室外墙预铺反粘防水技术应用

Application of Reverse Adhering and Pre-laid Waterproofing Technology for the External Wall of Super Deep Basement in Narrow Space

以郑州银行综合业务大楼项目为例,介绍了地下室外墙预铺反粘防水技术的应用,所介绍的做法与经验为地下室外墙与基坑支护排桩喷护层之间不留肥槽进行防水及结构施工提供了可行方案,也为同类型单侧支模部位预铺反粘法防水施工提供了技术参考。

Taking the comprehensive business building project of the Bank of Zhengzhou as an example,this paper introduces the application of the pre-laid and reverse adhering waterproofing technology for the basement exterior wall.The introduced practices and experiences provide a feasible scheme for the waterproofing and structural construction without leaving an extra construction trench between the basement exterior wall and the shotcrete layer of the foundation pit retaining row piles,and also provide a technical reference for the waterproofing construction of the pre paved anti adhesive method at the same type of unilateral formwork support position.
