| 摘 要： | 阐述了在冬季施工一设计为C35、P12抗渗混凝土基础底板的施工工艺 ,施工时正值冬季 ,施工时对厚度大于等于 1m的底板不掺防冻剂。对小于 1m的底板掺JD - 10防冻剂 ,混凝土配合比统一配制 ,采用分层浇筑、阶梯式推进的方法。沉降后浇带混凝土提前浇筑 ,约在混凝土整体收缩完成 80 %左右拆模。

| Abstract: | The construction process of C35、P12 leakage resistance concrete base floor in winter is expounded. Because of winter, the frostbite prevention agent isn't seeped in floor when the floor is large or equal to 1m thick. It is seeped in JD-10 frostbite prevention agent when it is smalle to 1m thick and using level casting stepping move. The sinking back casting concrete is poured in advance. The form removal is when the concrete shrinks 80%. |
