摘    要:在立塔施工中,采用了可拆卸塔吊内附着抱箍和专设塔吊高空解体装置,提高了立塔施工效率;在架线施工中,采用了“二牵二”倒拉和“尾送”放线技术,解决了山区大跨越特殊地理条件下放线张力过大的难题。北江大跨越工程的立塔和架线技术的改进可为后期类似工程提供参考方案。

关 键 词:大跨越  立塔  架线  可拆卸塔吊  塔吊高空解体  二牵二  尾送

Abstract:For tower erection,the technology of disassembled tower crane attached with holding hoop inside and special tower crane for air disassembling device was adopted to increase tower erection efficiency.For line stringing,two-pulling-two inverse pulling and offal send-off line stringing technologies were used to solve difficult problems of line stringing under excessive tension under special geographical conditions in mountain areas for large crossing.The improved tower erection and ling stringing technologies ...
Keywords:large crossing span  tower erection  line stringing  disassembled tower crane  tower crane in air disassembling  two-pulling-two  offal send-off
