摘要
三代核电站建设的一大特点是模块化施工,在模块化施工过程中由于模块内部操作空间狭小,使得现场施工面临新挑战。为解决这些问题,从自密实混凝土的特性出发,利用其流动性、填充性、抗离析性能等特点,选择合适的配合比,充分利用其初凝和终凝时间,优化施工安排,避免留设施工缝,减少了不必要的施工工作,节省了工程费用,增强了结构的整体性,对模块化施工起到了较好的参考作用。
A major feature of the third-generation nuclear power plant construction is modular construction. The narrow operating space in the process of modular construction puts a new challenge to the on-site construction. In order to solve these problems, based on the characteristics of self-compacting concrete, the scientific use of its liquidity, filling performance, anti-segregation performance, selection of the appropriate mix proportion, taking full advantages of the initial and final set time, and optimizing the construction arrangements have prevented the construction joints, reduced unnecessary construction, saved the cost of the project, enhanced the integrity of the structure, and played a good role in guiding modular construction.
