我们数学系一班师生,在毛主席光辉《五·七指示》的指引下,一九七四年冬到泗水县贺庄水库进行开门办学,以水库建设中的实际任务带动《公社数学》的学习。现就我们在水库贺三提水站进行铺工放样的实际,谈一点体会。在铺设贺三引水渠时,我们小组负责铺撒桩号“0+820——0+900”一段。此段工程全是挖方工段,其渠底中心线桩皆已定好。铺工时,由中心桩按事先已计算好的尺寸分别向左、向右定出上口灰线。要求在渠底中心线上引出垂线方可定上口宽,从而与下一断面上口宽相连而画得灰线(图一)。
Under the guidance of Chairman Mao’s glorious “May 7 Directive,” a batch of teachers and students in the Department of Mathematics held a door-to-door operation in the Hezhuang Reservoir in Surabaya in the winter of 1974 and took “Commune Mathematics” as its practical task in reservoir construction. Learning. Now we are in the Reservoir He Santi pumping station for laying out the actual situation, to talk about some experience. During the laying of He-San Drainage Channel, our group is responsible for spreading the paragraph “0 + 820--0 + 900”. This section of the project are all sections of the excavation, the bottom of the canal sinking pile have been set. Paving time, the center pile according to the pre-calculated size, respectively, to the left, right to set the gray line on the mouth. It is required to draw a vertical line at the bottom of the canal bottom to set the mouth width so as to be connected with the mouth of the next section and draw a gray line (Figure 1).
