AI Technical Summary
Technical Problem
The existing drilling pile verticality measurement methods have problems with inaccurate offsets, resulting in poor pile verticality and affecting project quality.
Method used
A drilling control device for drilling piles is provided. The offset displacement of the drill rod top relative to the wire rope is measured through the wire rope and the positioning device, and the inclination of the column is corrected in real time to ensure the verticality of the drilling hole.
Benefits of technology
By directly measuring the perpendicularity of the drilling hole, the inaccuracy of the perpendicularity of the drilling rod above the ground is avoided, and the verticality of the pile and the quality of the construction are ensured.
