1956年,江苏无锡市城市建设局市政工程队进行某公路的施工测量时,对横断面的测量采用了边测边绘的方法,不仅节省工序,提高了测量效率,还保证了测量的准确性。现将公路横断面边测边绘法介绍于下: 测量工具:手水准仪,大尺,皮尺,手水准仪托竿(木制或竹制,须有整数的高度尺寸,如1.45公尺、1.50公尺等,以便易于扣算),十字形方向架,画图板,搁画图板架子(最好可以折合,便于搬动),花标杆,米厘方格纸(透明与不透明根据需要决定),橡皮,三角板,铅笔。
In 1956, Wuxi City Urban Construction Bureau municipal engineering team for a highway construction survey, the measurement of cross-section measurement using side edge mapping method, not only save the process, improve the measurement efficiency, but also to ensure the accuracy of the measurement . Now the cross-section of the road side edge survey method introduced in the following: Measuring tools: hand level, large ruler, tape measure, hand level support rod (wood or bamboo, there must be an integer height dimensions such as 1.45 meters, 1.50 km Ruler, etc., in order to facilitate deduction), cross-shaped frame, drawing board, drawing board shelves (preferably can be folded, easy to move), flower pole, meter square paper (transparent and opaque as needed), eraser , Set square, pencil.
