Technical Measures for Assembling Towers Adjacent to Power Line by Inside Suspension Pole with outside Pulling Wires

邻近带电线路组立铁塔施工给输电工程铁塔组立带来很多不便和安全隐患。采用内悬浮外拉线抱杆进行组塔施工时,临近带电线路组塔对其上拉线和吊件控制绳的布置有较大影响。通过计算拉线与临近电力线路的安全距离,细化输电铁塔组立施工计算模型,总结在多个邻近带电线路工程中采取的内悬浮外拉线抱杆组塔施工技术措施,为其他的邻近带电线路组立铁塔提供参考。

It is very inconvenient and unsafe to assemble towers adjacent to power line.When towers are erected by inside suspension pole with outside pulling wires,the adjacent power line will significantly affect the layout of outside pulling wires and the control ropes for lifting.By calculating the safe distance between the outside pulling wires and the adjacent power line,the calculation model for tower assembling construction is further refined.The paper summarizes the technical measures taken in many projects for assembling towers adjacent to power lines by inside suspension pole with outside pulling wires,which can be used as a reference for similar projects.
