Design and construction method of mass barite radiation protection concrete
The invention provides a large-volume barite radiation protection concrete design and construction method. The method comprises the steps of raw material entering acceptance check, concrete trial preparation, construction joint reserving, temperature measuring point arrangement, raw material construction temperature monitoring, mixing water cooling, concrete entering cooling, concrete pouring, vibrating, concrete curing and temperature monitoring. The barite radiation-proof concrete design scheme meeting the technical requirements is designed through different mix proportion tests, and the influence of factors such as a pouring mode, construction temperature control, construction joint treatment and a forming quality monitoring means on the forming quality and the radiation-proof effect of the barite radiation-proof concrete structure is fully considered in the subsequent construction process; all the processes are strictly controlled, the problem of shrinkage cracks caused by large temperature difference change of a concrete structure in the construction process is solved, the problem that the radiation protection requirement cannot be met due to the fact that a straight construction joint is reserved is solved, and the problems that a formwork support structure is unstable and the temperature difference of concrete pouring is uncontrollable due to the fact that the single-time pouring height is too high are solved.
本发明提供一种大体积重晶石防辐射混凝土设计施工方法，包括：原材料进场验收、混凝土试配、施工缝留设、温度测点布设、原材料施工温度监控、拌制水降温、混凝土进场降温、混凝土浇筑、振捣、混凝土养护及温度监控。本发明通过不同配合比试验设计出满足技术要求的重晶石防辐射混凝土设计方案，后续施工过程中充分考虑浇筑方式、施工温度控制、施工缝处理、成型质量监控手段等因素对重晶石防辐射混凝土结构成型质量及防辐射效果的影响，并对各过程严格把控，避免应施工过程混凝土结构温差变化较大造成收缩裂缝问题，避免因留设通直施工缝导致不满足防辐射要求的问题，避免因单次浇筑高度过高导致支模架结构不稳、混凝土浇筑体温差不可控等问题。
