山区输电线路全过程机械化施工设计方案研究

Study on Whole Process Mechanized Construction Design of Transmission Line in Mountainous Areas

输电线路全过程机械化施工主要工序包括物料运输、基础施工、组塔施工、架线施工、接地敷设等。受地形及交通影响,山区输电线路推进全过程机械化施工存在一定困难。结合川渝三通道500 kV线路工程特点,对山区全过程机械化施工方案进行研究,并对现场实施情况进行总结。针对主要工序、子工序提出了设计优化措施,为同类地区实施全过程机械化施工提供借鉴参考。

The whole mechanized construction in transmission line has several main processes,including material transportation,foundation construction,tower installation,installation of overhead conductors and ground wires,grounding work and so on.Because of severe traffic condition in mountainous areas,it is difficult to promote the mechanized construction in whole process.Combined with the characteristics of the third-channel of 500 kV transmission line connected to Sichuan and Chongqing,the construction programs of whole process mechanized construction in mountainous areas are studied,and the implementation experiences in this project are summarized.The optimized measures of design are put forward for the main processes and sub-processes,which provides a reference for the whole process mechanized construction under similar condition.
