地下室基坑采用内支撑的立柱与底板节点防水施工技术

The Waterproofing Construction Technology of Upright Columns and Slabs in the Basements Using Internal Bracing System

介绍了3种地下室基坑采用内支撑结构的立柱与地下室底板节点防水施工工艺,每个节点进行防水设计和施工时均采用水泥基渗透结晶型防水涂料、止水钢板、防水卷材等防水密封材料进行加强处理、多道设防,获得了良好的防水效果。

The paper introduces three kinds of basements using internal bracing system and their waterproofing construction technology between upright columns and slabs. CCCW, water-stop steel, waterproofing membrane and other sealing materials are adopted in the detail waterproofing design and construction, which gains excellent waterproofing effects.
