When use the total station to carry out connection surveying,extend a prism rangefinder on shaft top is inconvenient,may set the prism behind the shaft plumbing wire and carry out range observation.The prism needs to hug closely to vertical wire of plummet centering survey station while not to bump the vertical wire.In the case of aim at the instrument,the distance between prism leading edge and prism center is a constant,for reasons give above,the distance between total station and wire center is measured....

使用全站仪进行联系测量时,由于不便在井口架设棱镜测距,可以通过将棱镜放置在投点钢丝的后面,进行距离测量,在保证棱镜紧贴垂直对中测点的竖线,而又不碰动竖线,并使其对准仪器的情况下,棱镜前边缘与棱镜中心的距离是一常数,据此即可测得全站仪与钢丝中点的真实距离。
