44、可拆除墩柱模板。砼强度达到 30%前不得使其承受行人运输工具、模板、支架等荷载。大面积模板拆模时模板与砼面接触面积大,附着力大,为防止拆模时发生粘模现象,采用在模板边角小面积橇起,使空气进入模板与砼面之间,减小模板与砼之间的真空压力。2、3、墩柱砼浇筑施工工艺(1)墩柱砼浇筑施工墩柱砼采用拌与站统一拌制,砼输送车送至现场。墩柱砼浇筑前,依据规范与施工图纸要求按工序进行检查,重点检查以下几项:a、检查模板支撑就是否牢固;b、模板接缝拼接就是否漏浆;c、钢筋间距、位置及保护层;d、模板内有无杂物;e、模板接缝、错台、模板垂直度就是否满足规范要求;f、检查振捣人员分工定位情况,并经自检合格报请驻地监

45、理工程师签认后开盘浇筑。砼的拌与计量采用电脑操作控制;严格按试验配合比上料,拌与时间为不小于1、5 分钟,确保砼拌与均匀。在砼拌与过程中,控制砼拌合时间与砼浇筑速度,严格控制水灰比与砼的坍落度,确保搅拌出来的砼的质量。砼搅拌完成后,在搅拌地点与浇筑地点分别取样检测砼的坍落度,确保入模砼的坍落度控制在79cm 之间,并具有良好的与易性。砼的运输时以迅速、不间断为原则,采用砼运输搅拌车运输。文档编码:CE10U1Q3C8K5 HE7C8Z4F8I8 ZV2E5B10H2Q3文档编码:CE10U1Q3C8K5 HE7C8Z4F8I8 ZV2E5B10H2Q3文档编码:CE10U1Q3C8K5 HE7
