现代大桥工艺中,越来越多的钢箱梁应用于跨海钢箱梁大桥中,钢结构有稳定、结实和实用等特点,但是由于所处环境的不同也产生了各种问题,尤其以受环境影响很大的钢箱梁腐蚀生锈的问题为主进行了深入的研究,本文总结了钢箱梁的维修防锈涂装工艺,根据实际情况选择适合的涂装材料和方法以及完善防腐工艺使其正常施工,加强钢箱梁的质量控制,抓住要点使钢箱梁的寿命延长。
In the modern bridge process, more and more steel box girders are used in the steel-pipe girder bridge across the sea. The steel structure is stable, strong and practical. However, due to the different environments, various problems have arisen. In particular, The corrosion of the steel box girder, which is greatly influenced by the environment, has been studied in depth. This paper summarizes the rust-proof coating technology for steel box girder maintenance, selects suitable coating materials and methods and perfects the anti-corrosion Technology to make it normal construction, strengthening the quality control of steel box girders, seize the key points to extend the life of steel box girder.
