在木材流送河川上,解决木材过坝是一个重要的问题。过去,我们一般采用斜坡式滑道,这种滑道在水位较高的情况下,为了达到要求的流速,就要适当变缓坡度,或采用加固措施,这样必然引起工程量的增加和施工的麻烦。 1965年以来,我区广大林业职工,在毛主席无产阶级革命路线指引下,经过十几年的生产斗争实践,摸索出跌坎式滑道,进行木材过坝。这种方法具有投资省,收益大,安全可靠等优点。目前已在全区广泛采用。现将跌坎式滑道介绍如下。一、结构型式跌坎式滑道是在斜坡式滑道的基础上增设
Solving the problem of over-damming of timber is an important issue in the flow of timber to the river. In the past, we generally used the ramp slide, this slide in the case of high water levels, in order to achieve the required flow rate, it is necessary to moderate the slope, or the use of reinforcement measures, which will inevitably lead to increased the amount of construction and construction trouble. Since 1965, under the guidance of Chairman Mao’s proletarian revolutionary line, the vast number of forestry workers in our region have worked out more than 10 years of practice in the struggle for production to find out the hurdle slides and carry out wood dam crossing. This method has the advantages of investment, large profits, safe and reliable. Currently widely used in the region. Now drop-type slide described below. First, the structure of the type-hitch Chute is based on the ramp-chute addition
