Concrete pouring method with ultra-large area and ultra-large volume
According to the pouring method for the concrete with the ultra-large area and the ultra-large volume, the hydration heat reaction is reduced through the measures of optimizing the proportion, increasing the using amount of the admixture, reducing the using amount of cement, prolonging the retarding time, controlling the mold entering temperature and the like, and the purpose of preventing the concrete from cracking is achieved; for super-large-volume and large-volume concrete pouring construction, a multi-point supply mode is adopted, and large-volume concrete supply within a short distance and a short time is achieved; during pouring, pouring construction is conducted according to the principle of plane zoning synchronous pouring and vertical non-layering, an anchorage foundation is divided into a plurality of pouring zones according to a pouring plane, the multiple zones are synchronously poured in the same plane, and pouring construction is completed from the periphery to the center in the same plane; after the first layer of concrete is poured, the second layer of concrete is poured, layered material distribution is carried out during pouring, one-time and uninterrupted concrete pouring construction is achieved, and the construction efficiency is greatly improved while organization coordination, safe production and construction quality are guaranteed.
本发明提供了一种超大面积、超大体积的混凝土浇筑方法，本发明通过优化配比，提高掺合料用量、减少水泥用量、延长缓凝时间、控制入模温度等措施降低水化热反应，达到防止混凝土开裂的目的；对于超大体积、大方量的混凝土浇筑施工，采用多点供应的方式，实现在短距离短时间内混凝土的大量供应；浇筑时，采用采用“平面分区同步浇筑、竖向不分层”的原则进行浇筑施工，将锚碇基础根据浇筑平面划分为多个浇筑分区，在同一平面内多个分区同步浇筑，在同一平面内由四周往中心完成浇筑施工，在第一层浇筑完成后返回进行第二层混凝土浇筑，浇筑时分层布料，实现一次性、不间断混凝土浇筑施工，在保证组织协调和安全生产，保障施工质量的同时，大大提高了施工效率。
