Description

Technical Field

[0001] The utility model belongs to the field of engineering measurement, in particular to a precise elevation transmission device used for monitoring the settlement of large-area buildings. Background Art

[0002] The elevation information of traditional ground leveling points cannot be linked with total station observations, that is, precise elevation information is obtained by driving leveling observation nails into the ground through leveling observations. However, the ground leveling points cannot effectively transmit their elevations to the main body of the monitored object during building (structure) settlement monitoring, resulting in a separation between the ground elevation and the building (structure) settlement monitoring points. The traditional improved device adds a fixed single-sided prism to the leveling observation nail. The device has low elevation transmission efficiency and is not convenient for multi-directional total station observations. It increases the time cost and labor cost of observation to a certain extent. In addition, when the prism is manually disassembled for steering, it is easy to cause deformation of the leveling point itself, increasing the system error and human error of the monitoring. Its observation effect is difficult to meet the accuracy requirements of elevation transmission. Utility Model Content
