利用全站仪激光对点器对井下投点的方法

竖井联系测量中,利用全站仪进行竖井投点,在近井点设站,罐笼与井壁间隙处选两个临时点,测出两点坐标。分别在两个临时点摆站,利用全站仪激光对点器将其点位在罐笼与井壁间隙中间投于井下。实践证明全站仪激光对点器对井下投点的方法投点方法简便,点位选择灵活,不需要多余记算,不用添置专用仪器,是行之有效的测量方法。

THE METHOD OF SHAFT PLUMBING IN UNDERGROUND WITH TOTAL STATION LASER PLUMBING INSTRUMENT

For shaft connection measuring,shaft plumbing will be made with total station,then stations are set up at the near-shaft control points with choosing two temporary points in the interstices between cage and shaft wall and measuring the coordinates of the two points.Plumb in underground is made in the middle of the interstice between cage and shaft wall using total station laser plumbing instrument after setting up stations at the two temporary points. In practice,it is a trial,true and easy surveying method...
