摘要
结合石武客运专线预制箱梁施工,介绍了在夏季高温施工条件下,通过严格控制混凝土温度、降低内外温差、预防收缩缝、减少混凝土坍落度损失、延缓凝结时间,控制混凝土裂缝所采取的一系列技术措施及其取得的效果,以积累相关施工经验。
Combined with Shi-Wu passengers dedicated line prefabricated line construction,in the summer high temperature construction condition,a series of technical measures and obtained effect of strict controlling concrete temperature,reducing inner and out temperature difference,preventing shrinkage joint,reducing concrete slump constant loss,prolonging condensing time and controlling concrete crack,so as to accumulate related construction experience.
