摘要
为解决采空区输电线路塌陷而引起的一系列诸如杆塔倾斜、杆塔位移、导地线间距与张力变化、基础差异沉降等问题,根据采空区杆塔的特征研制了系列工器具,经现场使用,有效解决了原有作业方式繁琐、复杂、强度大的难题,达到了预期效果,保证了线路安全稳定运行。
To solve a series problems caused by the transmission line’s collapsion in gob, such as tower tilt, tower displacement, change of spacing and tension on cables, differential foundation settlement and other issues,a series of special tools and instruments were developed based on the characteristics of tower in gob. Its application on site proved it an effective way to solve the original problems,and the desired effect was achieved, which ensured safe and stable operation of the line.
