玻璃钢是种由树脂与玻璃纤维布经层贴层压而成的塑料。用以制作测量工具,具有轻便耐用、节约木材等优点。几年来,各单位自力更生、土法上马,先后试制成功玻璃钢塔尺、折尺、水准尺、花杆、二米横基尺、斜丝视距尺、等差级数视距尺,小平板、无标尺测距装置、标石印模、以及图筒等各种测量工具。经过野外作业的实际考验,受到野外测量生产人员的欢迎。 FRP is a kind of plastic made of resin and glass fiber cloth laminated by layers. Used to make measuring tools, with advantages of light and durable, saving wood and so on. Over the past few years, various units have become self-reliant and indigenous methods. They have successively succeeded in trial production of fiberglass tower feet, folding feet, leveling feet, flower poles, two-meter cross-base feet, oblique wire sightlines, equal-difference progression sight gauges, and small flat panels. No scale measuring device, marking stone, and drawing tube and other measurement tools. After the actual test of fieldwork, it was welcomed by field surveying production personnel.
