摘　　要：由于土地征用的日益紧张,输电线路走廊变得越来越狭窄,塔型也更加繁杂,加上部分塔位交通条件差,大型起重机械难以到位,常规方法施工不能保证到施工安全和质量,也不利于工程进度。为此,文中介绍使用400mm断面人字抱杆组立高强度水泥杆这一特殊的杆塔组立施工方法,保证了施工的安全和质量,提高了施工效率,保障了施工工期,并为今后输电线路钢管塔等组立工作提供了经验。Due to increasingly difficulties in land expropriation, right-of-way of power transmission lines becoming narrower and narrower, types of tower having more and more complicated, and due to the limits of transportation condition of tower position, which is hard for heavy cranes to arrive on site, these factors have influenced on the safety and quality of construction, and would also affect the construction progress. To solve the problem, a special tower erection method for erection of high strength concrete poles, i.e. use of 400 mm section derrick was introduced in this paper, which could ensure safety and quality of construction, improve the efficiency of construction, accelerate the construction speed, and also accumulate the experiences for installation of steel tube towers in the future.
