随着输电线路建设的增多,国家建设的加快,线路走廊越来越窄。输电线路与重要构(建)筑物或设施的距离越来越近,如何在要求的工期内安全地完成输电线路岩石类基础坑开挖的施工是摆在施工单位面前的一个问题。本文通过介绍110KV瓦泾水电站的输电线路ANI,AN2和N283塔位岩石类基础坑开挖的施工实例,指出邻近重要构(建)筑物或设施的输电线路岩石类基础坑开挖的施工方法。
With the increase of transmission line construction, the construction of the country is accelerating, and the line corridor is becoming narrower and narrower. How to safely complete the excavation of the rock foundation pit for the transmission line within a required time limit is a problem placed before the construction unit, as the distance between the transmission line and the important structures or buildings is getting closer. This paper introduces the construction examples of the excavation of the rock foundation pit at the ANI, AN2 and N283 transmission lines of the 110KV Wawajing Hydropower Station and points out the construction method of the rock foundation pit excavation of the transmission line adjacent to the important structures or facilities .
