运材岔线使用期较短,建筑费用很高,需要寻求经济的岔线结构和最佳铺设方案。 1977年,笔者提出了建筑装车场环形设置的岔线方案。该方案如下:不象通常那样把岔线修到伐区的尽头,在岔线末端修空车环行道(图1,a)或运材转向场,而把岔线修到还差500～600米到伐区的尽头的地方, The transportation material fork line has a short service life and a high construction cost, and needs to seek an economic fork line structure and an optimal laying plan. In 1977, the author proposed a forklift scheme for the ring of the construction loading yard. The program is as follows: not as usual, the fork cut line to the end of the cutting area, trimmed at the end of the forklift car road (Figure 1, a) or shipped to the steering field, and the repair of the fork line is still worse 500 ~ 600 Rice to the end of the cutting area,
