Catwalk transverse overbridge suitable for space cable suspension bridge
The invention relates to a catwalk transverse overbridge suitable for a space cable suspension bridge, and belongs to the technical field of bridge construction, and the catwalk transverse overbridge comprises catwalk gantries which are fixedly arranged on catwalk main cables on the upstream and downstream of the suspension bridge respectively; and the two ends of the transverse channel are used for being connected with the upstream and downstream catwalk gantries of the suspension bridge correspondingly, and the transverse distance between the upstream and downstream catwalk gantries of the suspension bridge is changed by adjusting the length of the transverse channel. Therefore, the transverse span adjustment of the catwalk can be realized, the transverse distance of the catwalk portal frame can be adjusted according to the change of the relative mounting distance of the upstream and downstream main cables in the construction process of the suspension bridge, the subsequent mounting construction is facilitated, the construction flexibility is improved, and the change of the line shape of the main cables can be well adapted; according to the space cable suspension bridge main cable erection device, the requirements of space cable suspension bridge cable strand erection and space cable conversion for catwalk arrangement are met, the problem of space-variable main cable construction in the space main cable suspension bridge construction process is solved, the construction efficiency of space cable suspension bridge main cable erection is greatly improved, and safety and economical efficiency in the construction process are guaranteed.
本申请涉及一种适用于空间缆悬索桥的猫道横向天桥，属于桥梁建设技术领域，包括猫道门架，其分别用于固设在悬索桥上下游的猫道主索上；横通道，其两端分别用于连接悬索桥上下游的猫道门架，所述横通道通过调节自身长度以改变悬索桥上下游猫道门架的横向间距。因此，可以实现猫道的横向跨度调整，根据悬索桥在施工过程中上下游的主缆安装的相对距离的变化调整猫道门架的横向间距，方便后续安装施工，提高了施工灵活性，能较好的适应主缆线形的变换，满足了空间缆悬索桥索股架设和空间缆转换对猫道布置的需求，解决了空间主缆悬索桥施工过程中变间距主缆施工难题，大大提高了空间缆悬索桥主缆架设的施工效率，保证了施工过程中的安全性和经济性。
