Mass concrete construction method under severe cold climate
The invention discloses a mass concrete construction method under severe cold climate, belongs to the technical field of concrete construction, and solves the problems of low concrete strength, weak structural shock resistance and insufficient heat supply utilization in the prior art. Comprising the steps of building a heat preservation greenhouse, installing a small steam boiler outside the heat preservation greenhouse, conducting concrete construction, conducting steam curing and cooling. The internal cooling measure adopted by conventional mass concrete is broken through, the temperature and humidity of the environment where the concrete is located are increased through steam curing to control the internal and external temperature difference of the mass concrete, and the strength of the concrete is improved; one-time integral concrete pouring construction and comprehensive temperature control construction are combined, so that the anti-seismic capacity of the structure is improved while the concrete strength and integrity of the structure are improved; the heat supply advantage of northern severe cold areas is fully utilized, and the disadvantages that circulating water needs to be adopted for cooling the interior of concrete, and water in severe cold weather is poor in flowability and prone to freezing due to too low water temperature are avoided.
本发明公开了一种严寒气候下大体积混凝土施工方法，属于混凝土施工技术领域，解决了现有技术中混凝土强度低、结构抗震能力弱、未充分利用供热的问题，包括搭设保温暖棚、在保温暖棚外安装小型蒸汽锅炉、混凝土施工、蒸汽养护以及降温。本发明打破常规大体积混凝土采用内部降温的措施，采用蒸汽养护提升混凝土所处环境温度和湿度来控制大体积混凝土的内外温差，令混凝土强度得到提高；将一次性整体混凝土浇注施工和综合温控施工相结合，提高结构的混凝土强度和整体性的同时提高结构的抗震能力；充分利用北方严寒地区供热优势，避免混凝土内部降温需采用循环水，而严寒气候下水流动性差、水温过低易冻结的劣势。
