AI Technical Summary

Technical Problem

The existing total station prism adapter lacks automatic coordinate transformation and angle calculation functions, which requires construction workers to frequently move the equipment repeatedly in narrow foundation pits for trial and error positioning, increasing safety risks and reducing work efficiency.

Method used

A total station prism adapter based on angle measurement was designed. By changing the driving direction of the motor, the rotating cylinder and laser pointer are driven in a time-sharing manner, so that they rotate at a specified azimuth and tilt angle. Combined with the Pythagorean theorem, the pile foundation point position is automatically calculated. A single motor replaces a multi-motor system to ensure accurate positioning of the laser pointer.

Benefits of technology

It enables precise pile foundation location without frequent equipment movement, simplifies equipment complexity, improves positioning accuracy and efficiency, and reduces construction risks.

Abstract

The invention relates to the technical field of construction measuring equipment, in particular to a total station prism adapter for positioning the axis of a circular pipeline based on angle metering and a measuring method, and the total station prism adapter comprises a measuring mechanism, and a support frame and an angle meter which are arranged on the outer side of the measuring mechanism, the measuring mechanism is sequentially provided with a prism, a long rod, a rotating part, a connecting part and a ground inserting rod from top to bottom. According to the total station prism adapter for positioning the axis of the circular pipeline based on angle measurement and the measurement method, after primary pile foundation point position measurement is completed, a local coordinate system is established based on an original point at the bottom end of a ground inserting rod by utilizing the angle measurement instrument, and azimuth angle and inclination angle parameters are automatically output by utilizing the Pythagorean theorem; the specific position of the pile foundation point position is irradiated through the laser pen, so that a constructor does not need to frequently move equipment in an excavated foundation pit for trial and error positioning, and the time for positioning the axis of the circular pipeline before the circular pipeline is pre-buried is saved.
