针对惠来电厂4号汽轮发电机底板大体积混凝土施工项目,确定大体积混凝土施工过程中各材料的选择及供应情况,通过合理的混凝土配合比以及现场准备工作,为混凝土的顺利浇筑提供保障。介绍大体积混凝土的温度控制计算公式,提出养护、保温和测温的具体措施;最后选用合理的浇筑顺序和浇筑方法进行混凝土浇筑。通过以上各种措施,避免了混凝土养护过程中产生大量温度裂缝,达到预期强度要求,确保了施工质量。
In view of the massive concrete construction project of Huilai Power Plant Turbine No.4 Turbine Generator, determine the material selection and supply situation in mass concrete construction process, and ensure the smooth pouring of concrete by reasonable mix proportion of concrete and on-site preparation work . The calculation formula of mass concrete temperature control is introduced, and concrete measures of curing, heat preservation and temperature measurement are put forward. Finally, a reasonable pouring sequence and pouring method are adopted to pour concrete. Through the above various measures, to avoid a lot of temperature cracks in the concrete curing process to achieve the expected strength requirements to ensure the construction quality.
