METHOD trigonometric leveling

摘要

FIELD: measurement equipment.;SUBSTANCE: when laying a lengthy path of trigonometric levelling a tool is installed as capable of sighting for a row of path points, but at least 2. Sighting is carried out to all visible path points, but at least two, at the same time sight targets (reflectors) are installed at one height from the peg (rack) heel. Excesses between points are determined as differences of horizons of each taken path point.;EFFECT: improved accuracy and efficiency of measurements.;1 dwg
