动力伞展放导引绳在特高压线路施工中的应用

Application of Pilot Rope Laying by Powered-Umbrella in EHV Transmission Line Construction

在输电线路张力架线施工中,导引绳一般使用人力展放,对农田和地表环境造成一定的影响,特高压线路架线施工采用环保型的飞行器展放导引绳技术,有很好的综合效益。能用于展放导引绳的飞行器类型比较多,而且各有特点,通过对飞行器展放导引绳施工技术、施工工艺的深入研究,汇总分析多家的施工实践,结果表明,目前选用动力伞展放导引绳在经济技术上比较合理。

The pilot rope is generally laid by manpower during transmission line stringing and this method may cause damages to the farmland and ground environment. The environment-friendly flying machine used for the pilot rope laying for the HV transmission line stringing, however, has sufficient comprehensive benefits. There are many kinds of flying machines used for the pilot rope laying, each of which has its own characteristics. Focusing on the study of construction techniques and workmanship for the pilot rope laying by different flying machines, this paper summarizes and analyzes many construction practices, and concludes that using the powered umbrella for pilot rope laying is both technically and economically reasonable.
