摘　　要：以某输电线路为例探究了绝缘索桥跨越铁路施工技术的应用。该工程中使用了动力伞辅助完成导引绳的带电跨越展放,在降低操作难度的基础上保证了作业人员的安全。地面组装绝缘索桥和安装索桥支架后,利用机动绞磨机完成绝缘索桥的牵引,最后调整索桥主承载绳的弧垂,弧垂达到要求后将牵引绳绑扎牢固,在输电线路的跨越施工后拆除绝缘索桥,高效且安全地完成了本次输电线路跨越铁路施工任务。Taking a certain transmission line as an example,this paper explores the application of insulation cable bridge crossing railway construction technology.In this project,a power parachute was used to assist in the live crossing and deployment of the guide rope,ensuring the safety of the operators while reducing the difficulty of operation.After the insulated cable bridge is assembled on the ground and the cable bridge support is installed,the traction of the insulated cable bridge is completed by using a motorized winch.Finally,the sag of the main bearing rope of the cable bridge is adjusted.After the sag meets the requirements,the traction rope is bound firmly.After the crossing construction of the transmission line,the insulated cable bridge is removed,and the construction task of the transmission line crossing the railway is completed efficiently and safely.
