Anti-aging structure and method along with dam concrete strength increasing period
The invention relates to an anti-aging structure with dam concrete strength increase, which comprises a dam heat preservation and moisture preservation structure in a pouring period, and an anti-aging structure after the dam heat preservation and moisture preservation structure in the pouring period is dismantled after dam pouring is completed. The dam moisturizing sealing layer, the dam heat preservation and moisturizing layer and the dam heat preservation and moisturizing layer protection layer are sequentially arranged along the concrete base surface from inside to outside; the invention further provides an anti-aging method for the dam concrete strength increasing period. According to the method, the heat preservation and moisture preservation maintenance work is moved forward, heat preservation and moisture preservation are carried out at the beginning of concrete warehousing, the good heat preservation and moisture preservation effect is achieved in the early stage of dam concrete strength increasing, and effective and timely protection is carried out in different stages of strength increasing of the dam concrete. The problems that the concrete base surface is rich in moisture, and polyurethane material spraying construction cannot be carried out in time while formwork removal is carried out are solved, heat preservation and moisture preservation of dam concrete do not have a window period, and effective protection in the key period of concrete strength increase is achieved.
本发明涉及一种伴随大坝混凝土强度增长的防老化结构，包括浇筑期大坝保温保湿结构，和大坝浇筑完成边拆除所述浇筑期保温保湿结构后，边沿混凝土基面从里向外依次设置的大坝保湿封闭层、大坝保温保湿层和大坝保温保湿层防护层；本发明还提供了一种伴随大坝混凝土强度增长期的抗老化方法。本发明将保温保湿养护工作前移，从混凝土入仓开始就进行保温保湿，在大坝混凝土强度增长早期就起到良好的保温保湿效果，并伴随其强度增长不同阶段都进行有效及时的保护，本发明有效解决了刚拆模的大坝混凝土，因混凝土基面富含潮气，无法边拆模边及时进行聚氨酯材料喷涂施工的难题，让大坝混凝土保温保湿没有空窗期，实现混凝土强度增长关键时间段的有效保护。
