Problems solved by technology

[0003] Using the existing means, the steps are complicated, and the operator needs to use the centering rod and the measuring nail to align each time, and it is necessary to install the three brackets of the centering rod before centering, which not only reduces the efficiency, but also affects the accuracy. The operator requires high skill and patience, and is prone to accidental errors, which is not conducive to ensuring accuracy

Abstract

The invention discloses a prism for a total station. The prism for the total station comprises an upper prism component, a middle connecting component and a lower embedded component, wherein the upperprism component comprises a prism and a prism support, the prism is rotationally connected with the top of the prism support, a prism support level gauge is mounted on the prism support, and a firstfixed upright post is arranged at the bottom of the prism support; the middle connecting component comprises a second fixed upright post, the bottom of the first fixed upright post is connected with the top of the second fixed upright post by virtue of one universal connecting piece, and a screw is arranged at the bottom of the second fixed upright post; and the lower embedded component comprisesa sleeve nut which is used for being matched and connected with the screw, a steel plate sheathes the top of the sleeve nut, and embedded reinforcement is arranged at the bottom of the sleeve nut. Theprism for the total station is simple in structure and reasonable in design, not only is measurement efficiency high, but also an accidental error caused by manual centering can be effectively avoided, and the measurement accuracy of foundation pit monitoring is improved.

Description

technical field [0001] The invention relates to the field of distance, level and orientation measurement, in particular to a total station prism. Background technique [0002] In the existing foundation pit monitoring, after setting the elevation reference point, the monitoring points of the foundation pit and supporting structure should be arranged along the periphery of the foundation pit, the horizontal distance between monitoring points should not be greater than 20m, and the number of monitoring points on each side should not be less than 3. Among them, the horizontal and vertical displacement monitoring points should be common points, and the monitoring points should be set on the enclosure wall or the slope top of the foundation pit; when the monitoring point is buried on the top of the crown beam, after the embedding point is selected, use an electric drill to form a hole on the crown beam , and then insert the measuring pin. The principle of foundation pit monitori...
