【摘要】 本文叙述了防腐综合技术在厦门海沧大桥混凝土桥墩潮差区和浪溅区部位的防腐蚀维修工程的应用,包括防腐综合技术的设计、施工和检测评定。防腐综合技术由重防腐涂料体系和牺牲阳极的阴极保护技术组成。重防腐涂料由混凝土表面专用的渗透型底漆和厚膜防腐面漆组成,适用于潮差区的混凝土湿表面。牺牲阳极材料以锌合金为主,少量铝合金作为平行对比应用试验。整个工程已在2010年7月通过合格验收,达到了防腐保护的效果。更多还原

【Abstract】 The paper described the application of comprehensive corrosion protection technique on maintenance for concrete Piers on tide zone and splashing zone in Haicang Bridge Xiamen,including design,application and performance check.The corrosion protection technique combined heavy-duty coating system and cathodic protection (sacrificial anodes).The heavy-duty coating system composed a permeable primer and a high-build anticorrosive top coating;both were suitable to the wet surface of concrete.The sacrificial anodes included zinc alloy and aluminum alloy,as comparison test.The complete project has been checked in July 2010 and showed the results of corrosion protection.更多还原
