当前输电线路施工过程具有点多、线长的特点,通道内存在难以确定树木砍伐范围、全线测量不切合实际等困难.因此,提出了利用设计院提供的平断面图初步筛选砍树范围,进而可确定出通道内需要砍伐树木的区域,再结合现场测量形成最终的树木砍伐范围.通过应用该方法,在施工中节省了大量的测量时间,进一步提高了工作效率.

Because of the multi-points and long lines in the process of transmission line construction, it is difficult to determine the tree-felling scope within channels and it is not practical to measure the full range. This paper proposes to sift initially the tree-felling scope with flat cross-section diagram provided by institute. First, we should identify the places trees to be felled within the channel and then determine the final tree-felling scope combined with site survey. Through specific practical applications, this method saves much measuring time and energy in the construction and the efficiency is further improved.
