黄石体育馆地下工程防水施工技术

Waterproofing Technology of Huangshi Gymnasium Underground Works

黄石体育馆地下工程采用了刚柔结合的复合防水设计。主体结构刚性防水采用强度等级为C30、S8的防渗混凝土,后浇带刚性防水采用强度等级为C35的微膨胀混凝土;根据不同工程部位的不同防水等级,附加防水层分别采用了APP改性沥青防水卷材、APP改性沥青防水涂膜和水泥基渗透结晶型防水涂料,并对桩头、后浇带、施工缝等节点部位作了加强处理。

The waterproofing design of Huangshi Gymnasium Underground Works adopts rigid-flexible technology.Its main structure uses impervious concrete of S8,C30 and post-pour strips use micro expansive concrete of C35.In addition,APP modified bitumen waterproofing membrane,liquid applied APP modified bitumen waterproofing system and CCCW coating are used as additional waterproofing layer for different positions of the works.And pile heads,post poured strips and construction joints are reinforced as well.
