Accurate triangle elevation of total powerstation is crossed river level and is measured auxiliary device
Technical Field
The utility model relates to the technical field of triangular elevation river-crossing level measurement, in particular to a precise triangular elevation river-crossing level measurement auxiliary device of a total station.
Background
With the rapid development of cities, more and more projects are passed through rivers, however, in the construction process, the traditional geometric leveling method is adopted to pass over the existing bridge, most of bridges have large vehicle flow, generate large vibration, and the geometric leveling method is adopted to ensure long crossing distance and poor data quality, so that the precision requirement cannot be met.
In recent years, with the development of total stations, particularly automatic alight total stations having automatic recognition, alight targets, high-precision angle measurement and ranging, precise triangulation has become possible instead of conventional high-level leveling. However, the normal precision triangulation engineering measurement needs to be matched by multiple people, for example, 2-4 auxiliary people are needed to be equipped, the prism is required to be continuously rotated in each measuring process, and the prism is required to be rotated back to the original position after each measuring process is finished. Inconvenient measurement and low efficiency.
Therefore, how to improve the efficiency and convenience of the precision triangulation engineering measurement is an urgent problem in the current field.
