Ultrahigh bridge tower concrete curing structure and curing method
The invention discloses an ultrahigh bridge tower concrete curing structure and curing method. The maintenance structure mainly comprises a moisture preservation layer, a heat preservation layer, nylon hook-and-loop fasteners and connecting tying belts. The inner side of the moisturizing layer is adhered to the surface of concrete, and the outer side is covered with the insulating layer; the heat preservation layers are manufactured in a partitioned mode, and the two heat preservation layers are firmly tied through nylon hook-and-loop fasteners and connecting tying belts in the horizontal direction. When the maintenance structure is matched with an ultrahigh bridge tower hydraulic creeping formwork tower building system for use to maintain ultrahigh bridge tower concrete, all the side faces of a bridge tower are subjected to full-wrapping covering maintenance, along with pouring of the upper tower section and overall upward movement of an operation platform, the moisture preservation layer does not move after being attached, the heat preservation layer moves synchronously, and maintenance is uninterrupted. The method effectively solves the problems that the early cracking risk is aggravated and the service durability of the structure is influenced due to serious surface water loss, large temperature difference between the inside and the surface and high temperature drop rate caused by difficult maintenance after the ultrahigh bridge tower body concrete is demoulded, and powerfully guarantees the construction quality of ultrahigh bridge tower engineering.
本发明公开了一种超高桥塔混凝土养护结构及养护方法。本发明所述养护结构主要包括保湿层、保温层、尼龙魔术贴及连接系带；所述保湿层内侧黏贴于混凝土表面，外侧贴覆保温层；所述保温层分块制作，两块保温层之间水平方向用尼龙魔术贴和连接系带系牢；采用上述养护结构与超高桥塔液压爬模筑塔系统匹配使用对超高桥塔混凝土进行养护时，对桥塔各个侧面进行全包裹覆盖养护，并随着上部塔节浇筑及操作平台的整体上移，保湿层贴覆后不移动，保温层同步移动，养护不间断。本发明有效解决超高桥塔塔身混凝土拆模后养护困难导致的表面失水严重、里表温差大、温降速率快，从而加剧早期开裂风险，影响结构服役耐久性的难题，有力保障超高桥塔工程施工质量。
