| 摘 要： | 介绍了超高压输电线路在张力架线施工中,不用传统的人工展放导引绳,采用氦气球展放一级引绳((?)mm迪尼玛绳),再用一级引绳牵二级引绳((?)4 mm迪尼玛绳),通过多级引绳的过渡,实现张力展放导引绳。提出三个技术方案可供选择,并介绍了与之相配合的软索跨越技术。文章对技术方案的施工计算和施工工艺做了详细的论述。

| Abstract: | This paper introduces the pilot rope laying by helium balloon instead of by traditional manual work when stringing in the construction of EHV transmission line.The first pilot rope((?)2mm Deenyma rope)is pulled by the helium balloon,then the second pilot rope((?)4mm Deenyma rope)by the first pilot rope.The pilot rope is laid out by tension through transfer of multi-ropes.Three proposed technical schemes can be selected,and the related live line cross technology by pilot rope is introduced.This paper de- scribes the construction calculation and workmanship of technical schemes in detail. |
