松花江哈尔滨段防洪模型长约50米,宽16米,制作这样大的模型约需200多张三合板或白铁皮,而且接缝漏水也比较麻烦.为此,我们学习了南京水利科学研究所和江西省交通规划勘察设计院用玻璃板制作模型水泥断面的方法,并在玻璃板安装支架等方面作了一些改进,经在哈尔滨模型制作中试用,效果尚好.现将使用情况及体会简述如下: 1.玻璃板的尺寸为厚4～5毫米、长200厘米、宽40厘米,四边平整,底边磨光.绘制玻璃板断面的工作台台边平嵌钢板尺.画断面时,将玻璃板底边与钢板尺重合或平行放置,以钢板尺作为起点距
Songhua River Harbin flood control model is about 50 meters long and 16 meters wide, making such a large model takes about more than 200 plywood or tinplate, and joints leaking too much trouble.To this end, we studied the Nanjing Institute of Water Conservancy and Jiangxi Province Transportation Planning Survey and Design Institute of glass plate production model of the cross-section of the method, and in the glass plate mounting bracket and made some improvements, after the trial in Harbin model production, the effect is still good. The use of the situation and experience are summarized below : 1. The glass size is 4 to 5 mm thick, 200 cm long, 40 cm wide, four sides smooth, polished bottom. Workbench glass panel cross-section plank inlaid steel ruler. Draw the cross section, the glass The bottom edge of the plate coincides with the steel ruler or parallel to the steel ruler as a starting point
