Description

A prismatic rod that is not easy to overturn

technical field

The present application relates to the technical field of prismatic rods, and in particular, to a prismatic rod that is not easily overturned.

Background technique

Prism pole is an important tool for obtaining 3D coordinates of points or construction stakeout in production measurement. Prism pole is often used together with total station, and is widely used in precision engineering measurement or deformation monitoring such as construction of large-scale above-ground buildings and underground tunnels.

The prismatic rod generally includes a main rod, two secondary rods, and a prismatic lens for reflecting the light emitted by the total station. Before the measurement, the tester places the total station on the known control point, and then informs the ruler to place the prism pole to the backsight point. At this time, the ruler inserts the main pole into the ground, so that the prism is roughly horizontal to the total station, and then adjusts the supporting angle of the auxiliary pole to center the bubble of the spirit level. After the ruler has calibrated the prism rod, the distance between the total station and the backsight point can be accurately obtained through the ranging function of the total station.

However, in some special occasions, such as areas with loose soil, the main rod of the prism rod is easily displaced after being inserted into the ground, which makes the prism rod sideways, which affects the accuracy of the measurement, and it is not convenient for the ruler to place the prism rod for subsequent follow-up. measurement work.
