摘要
介绍了深圳前海自贸区地标性建筑--景兴海上大厦的地下室底板设计与施工工艺:地下室基坑应用了内支撑,迎水面采用高分子自粘胶膜防水卷材预铺反粘施工,底板大体积混凝土内部预埋冷凝水管降低混凝土的内部温升,背水面采用水泥基渗透结晶型防水涂料,并在底板内侧设置了HDPE疏水板保障排水通畅。多道措施并举,确保了景兴海上大厦地下室底板不发生渗漏。
The article introduces the design and construction technology of the basement floor of Jingxing Sea Tower,the landmark of Qianhai Free Trade Zone in Shenzhen.Of which,inner support is adopted for the basement foundation pit;polymer self-adhesive film reinforced waterproofing membrane is applied on the water-facing side through pre-laid method;condensate pipes are embedded in the mass concrete of the floor to reduce the temperature rise inside;cement-based capillary crystalline waterproofing coating is used on the back side;and HDPE water draining panels are installed on the inner side of the floor to make sure unobstructed drainage.With all these measures mentioned above,leakage is completely avoided for the basement floor.
