云龙湾自锚式悬索桥桥梁管理微信小程序开发

目前国内桥梁混凝土的防腐防护措施尚不完善.在一些腐蚀性严酷的环境中,由于缺乏必要的防护措施,钢筋混凝土结构远不能达到预期的设计使用年限.弹性涂料作为一种新型材料,近年来发展迅速,其本身具有一定的伸长量,能够满足混凝土的胀缩工况.与普通涂料相比,弹性涂料能够更好地与混凝土协同工作,避免涂层表面因混凝土热胀冷缩而出现拉裂裂缝,从而最终导致防腐涂层失效.本项目开发旨在探索弹性涂料对于明州大桥拱座表面的防腐效果及长期防护性能,并为其他大体积混凝土工程防腐涂装施工提供一定参考.

The Development of Bridge Management Wechat Applet based on Yunlongwan Self-anchored Suspension Bridge

At present, the anti-corrosion protection measures of bridge concrete are not perfect in our country. The reinforced concrete structures is far from reaching the expected design life due to the lack of necessary protective measures. Elastic coating is a new material which has been developed rapidly in recent years. It has a certain amount of elongation and can satisfy the expansion and contraction of concrete. Compared with common coatings, elastic coatings can work better with concrete to avoid failure of anti-corrosion coating as a result of the tensile crack of coating surface caused by thermal expansion and cold contraction of concrete. The purpose of this project is to explore the anti-corrosion effect and long-term performance of elastic coating on the surface of arch seat of Mingzhou Bridge, and to provide certain reference for other mass concrete engineering anti-corrosion coating.
