江苏大剧院地下防水施工技术探讨

Discussion on Underground Waterproofing Application Technology of Jiangsu Theater

江苏大剧院地下底板、侧墙和顶板均采用S6结构自防水混凝土,同时底板采用2 mm+2 mm高分子双面自粘防水卷材,侧墙外设2 mm厚高分子双面自粘防水卷材,顶板采用4 mm厚SBS改性沥青防水卷材+4 mm厚耐根穿刺SBS改性沥青防水卷材。本文重点阐述了地下工程防水施工做法及裂缝处理工艺,同时对细部节点做法进行了详细说明。

S6 structure self-waterproofing concrete is adopted in the bottom plate, side walls and top plate of Jiangsu Theater underground work. Meanwhile, the bottom plate adopts 2 mm＋2 mm thick double faced polymer self-adhesive waterproofing membrane; side walls adopt 2 mm thick double faced polymer self-adhesive waterproofing membrane; top plate adopts 4 mm thick SBS modified bitumen waterproofing membrane ＋ 4 mm thick root-resistant SBS modified bitumen waterproofing membrane. The article elaborates on waterproofing application practice and crack treatment technology for underground works,and it also introduces treatment methods for details.
