采用动力伞放线的几点尝试

按传统方式放线，需要修整放线通道，比如砍伐通道内影响牵引绳起空的树木以及房屋拆迁等问题，常会出现非常大的地方民事阻碍，造成很大的经济损失，也对绿色自然环境造成了破坏与损伤，影响了生态环保。采取动力伞展放牵引绳的施工方法不仅缩短了施工时间，提高了放线效率，加快了电力基建工程进度，还大幅度降低了青苗补偿费用和人工成本费用，并减少放线施工中对果树及线路走廊内的林木和建筑物的破坏。本文探讨了动力伞放线在工程中的应用。

Several Attempts to Pay-off Unit by Using Powered Parachute

Traditional methods to pay-off need to repair and maintain the pay-off channel and the logging channel, which affects the traction rope construc- tion. It caused a large local civil obstruction and great economic losses, which destruct and damage on the natural environment. Powered parachute pay-off unit reduced the crops compensate, short- ened the construction period, improved the effi- ciency of pay-off, speeded up the progress of en- gineering project .This paper discussed the pow- ered parachute pay-off unit in engineering appli- cations.
