摘要
详细介绍了客运专线大体积承台高性能混凝土施工中,采取的温控措施及施工方法,通过优化配合比,在大体积承台混凝土内部预埋冷却水管降温、浇筑后在混凝土表面覆盖土工布保温等措施,对控制裂缝起到了很好的效果。
The paper introduces the temperature control measures and construction methods in the large pile cap high-performance concrete construction of the passenger special lines,and adopts some measures by optimizing the proportional ratio,pre-burying the cool water in the internal part of the large pile cap concrete to lower the temperature,and covering the concrete surface with the earthwork cloth for the insulation,so as to have the better effect of controlling the cracks.
