秦岭林区集材作业条件差,劳动强度大,成本约占伐区生产成本的60%以上。1985年以来,汉西林业局主要采取了冰雪滑道集材,取得了较好的效果。原理是:利用伐区的自然坡度,挖土筑槽,表面浇水结冰后构成半圆形的槽道(直径0.8～0.9m),靠木材自身的重力,沿着槽道进行下滑的一种集材方式。它的具体作法是:在冬季的夜间浇道,早晚放材,中午停放;放材时,将大
The working conditions of the timber in Qinling forest area are poor, and the labor intensity is large, and the cost accounts for more than 60% of the production cost in the cutting area. Since 1985, Hanxi Forestry Bureau has mainly taken the ice-skid skid timber and achieved good results. The principle is: using the natural slope of the cutting area, excavation of soil trough, the surface watering ice to form a semicircular channel (diameter 0.8 ~ 0.9m), by their own gravity of the wood, sliding along the channel to a Cultivated timber way. Its specific practices are: runner in the winter at night, morning and evening put the material, parked at noon; when placed on the material, will be large
