猫道是悬索桥上部结构施工重要的高空作业通道和施工平台,猫道的使用贯穿整个悬索桥上部结构安装工程的始终。随着时代的进步和科技的发展,猫道的材料和结构形式伴随着悬索桥的发展亦在不断改进。中交一公局承建驸马长江大桥,该桥施工难度大、技术难度高。项目部技术人员结合本工程特点,通过对猫道系统设计及施工方案进行合理地优化,极大提高了猫道施工效率,降低了安全风险,保证了施工质量。 The catwalk is an important aerial work channel and construction platform for the construction of the superstructure of the suspension bridge. The use of the catwalk runs through the entire superstructure of the suspension bridge. With the progress of the times and the development of science and technology, the materials and structure of the catwalk are also continually improved along with the development of the suspension bridge. The construction of the Changjiang Bridge, which is constructed by the Central Bureau of Communications and Public Works, has great difficulty in construction and high technical difficulty. Based on the characteristics of the project, the technical staff of the project department optimized the catwalk system design and construction scheme reasonably, which greatly improved the catwalk construction efficiency, reduced the safety risk and ensured the construction quality.
