精确测定地面高程的尺垫产品系列

Staff plate for accurately measuring ground elevation product series

特色与优点 Features and advantages

众所周知:使用传统三支脚尺垫,无法精确得出转点处的地面高程,造成了转点高程过期作废的现象。因此,精确保留转点处的地面高程一直是水准路线测量的难点之一,不少单位试图通过钉钉子的方式来解决,但是存在操作不便和破坏路面的缺点。本产品是在尺垫底部引入了第4个中心支脚,并且中心支脚底端与尺垫顶部球冠构成半球结构,使水准标尺底面与中心支脚的地表面接触点之间的高差保持恒定(球半径R),从而能精确测定(转点高程+R)出转点处的地面高程,提高水准路线测量的效益。

It is well known that the ground elevation at the turning point cannot be accurately obtained by using the traditional three leg staff plate, resulting in the phenomenon that the turning point elevation is expired after the measurement of leveling route. Therefore, accurately preserving the ground elevation at the turning point has always been one of the difficulties in leveling route measurement. Many users have tried to solve this problem by nailing nails, but it has the disadvantages of inconvenient operation and damage to the road surface. These products adopt the fourth central support foot at the bottom of the staff plate, and the bottom end of the central support foot and the spherical crown at the top of the staff plate form a hemispherical structure, so that the height difference between the bottom of the leveling staff and the contact point on the ground surface of the central support foot remains constant (ball radius R), so that the ground elevation at the turning point (turning point elevation +R) can be accurately measured, and the benefit of leveling route measurement can be improved.
