Mass concrete construction method
The invention discloses a mass concrete construction method, and relates to the technical field of building construction.The mass concrete construction method includes the steps that according to the requirement for the mixing proportion of concrete raw materials and calculation of the temperature of concrete entering a mold, when the temperature is lower than 10 DEG C, warm water is adopted for stirring concrete, hot water is sprayed to aggregate for heating, and when concrete pouring is conducted, hot water is sprayed to the aggregate for heating; a segmented and layered continuous pouring mode is adopted, pushing is conducted from deep to shallow in sequence, treatment and maintenance are conducted on concrete vibration compaction, concrete initial setting and final setting, concrete vibration compaction is guaranteed by arranging a front pouring belt, a middle pouring belt and a rear pouring belt, meanwhile, bleeding treatment is conducted when mass concrete is poured, and therefore the strength and quality of the concrete are guaranteed; and the risk of building cracking is reduced.
本发明公开了一种大体积混凝土施工方法，涉及建筑施工技术领域，本发明通过对混凝土原材料配合比的要求，同时对混凝土入模温度进行计算，在温度低于10℃时，采用温热水搅拌混凝土，对骨料喷热水进行升温，在进行混凝土浇筑时，采用分段分层连续浇筑方式，由深向浅依次推进，并且对混凝土的振实、混凝土初凝和终凝的处理和养护，通过设置前、中、后三个浇筑带，来保证混凝土振捣密，同时对大体积混凝土浇筑时泌水处理，从而来确保混凝土的强度和质量，降低建筑开裂的危险。
