Fire-proof and corrosion-proof sealing wrapping composite structure for main cable of suspension bridge and construction method of fire-proof and corrosion-proof sealing wrapping composite structure
The invention relates to a suspension bridge main cable fireproof anti-corrosion sealing wrapping composite structure and a construction method thereof. The suspension bridge main cable steel wire surface sequentially comprises an MS double-component sealant layer, a wire wrapping layer, an MS single-component sealant layer, a fireproof wrapping composite layer, an MS flame-retardant sealant layer and a coating from inside to outside. The fireproof wrapping composite layer is composed of an aerogel felt wrapping layer and a fireproof steel hoop, it is guaranteed that the aerogel felt wrapping layer cannot diverge or fall off when encountering fire, MS sealant is innovatively modified, related performance is remarkably improved, all structural materials are clean and environmentally friendly, and the whole system is easy and rapid to construct and durable in protection and has good economic and social benefits.
本发明涉及一种悬索桥主缆防火防腐密封缠包缠包复合结构及其施工方法，自悬索桥主缆钢丝表面由内向外依次包括MS双组份密封胶层、缠丝层、MS单组份密封胶层、防火缠包复合层、MS阻燃密封胶层、以及涂装涂层；防火缠包复合层由气凝胶毡缠包层外加耐火钢钢箍组成，保证气凝胶毡缠包层遇火不会发散或脱落，MS密封胶进行了创新型改性，相关性能显著提升，所有结构选材清洁环保，整个体系施工简单、快速，保护持久，具有良好的经济及社会效益。
