Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a measuring device for the elevation of a road crossing grid. Background technique [0002] The elevation measurement of road intersection grid is an important design basis for the design of road longitudinal slope and edge joint, and is a major task in the measurement task of municipal road engineering projects. The existing measurement process is mainly to use GPS-RTK to set out the road intersection grid first, then mark the points, and then use a total station or a level to measure the elevation of all the marked points. This requires three surveyors, one for GPS-RTK point placement, one for running poles, and one for operating total station survey points. Simultaneously, since the point is placed first for marking, and then the point is measured, the position of the point and the point for measurement inevitably deviates. It can be seen that the biggest disadvantage of t...
