500kV镇江大跨越电力安装工程是国家重点工程。该工程横跨长江,耐张段长2848m,共有两基跨江高塔和四基耐张塔。南塔位于地势险峻的五峰山上,塔高134.75m;北塔高179.75m;四基耐张塔高均为41.05m。六基塔总重约1100t,有24.8万套螺栓等紧固件,最大组合构件吊重约15t,吊装高度最高达179.75m。我公司根据送变电施工行业“基础抓质量,立塔抓安全,架线抓工艺”的经验,施工前进行周密的准备,施工中进行严格管理,终于在吊装量大、技术难度高、气候条件复杂的条件下,仅用5个月又12天时间,圆满完成立塔任务,比计划工
500kV Zhenjiang large span power installation project is a national key project. The project across the Yangtze River, Zhang segment length 2848m, a total of two bases across the river tower and the four basement tensile towers. South tower is located in the steep terrain of Wufeng Mountain, the tower of 134.75m high; North Tower 179.75m high; four base tensile towers are 41.05m high. The total weight of the tower is about 1,100 tons. There are 248,000 bolts and other fasteners. The maximum combined weight of the tower is about 15t and the height of the tower is up to 179.75m. According to the experience of sending construction of substation construction industry based on the principle of “grasping the quality, building a tower, safety of the line, grasping the process”, the company carefully prepared before the construction and carried out strict management during the construction. Finally, Conditions of complex conditions, only 5 months and 12 days time, the successful completion of the tower task, than the planned workers
