Title:
INTELLIGENT CORE DRILLING MONITORING SYSTEM HAVING EARLY-WARNING FUNCTION AND MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/078334
Kind Code:
A1
Abstract:
An intelligent core drilling monitoring system having an early-warning function and a monitoring method. The monitoring system comprises a drilling rig and a monitoring assembly; the drilling rig comprises a drill rod (6), an upper crossbeam (1), a lower crossbeam (2), and vertical shafts (3); the upper ends of the vertical shafts (3) are fixedly connected to the upper crossbeam (1); the lower ends of the vertical shafts (3) penetrate through the lower crossbeam (2) and can move up and down relative to the lower crossbeam (2); the drill rod (6) penetrates through the upper crossbeam (1) and the lower crossbeam (2) and can move up and down relative to the upper crossbeam (1) and the lower crossbeam (2); the monitoring assembly comprises springs (4), pressure sensors (5), and displacement sensors (7); the springs (4) are sleeved on the vertical shafts (3) and are located between the upper crossbeam (1) and the lower crossbeam (2); the pressure sensors (5) are mounted on upper and lower ends of the springs (4); and the displacement sensors (7) are mounted on the lower crossbeam (2), and the top portions of the displacement sensors abut against the upper crossbeam (1). A real-time monitoring function for core drilling is implemented by means of compression deformation of the springs (4), defects monitored by a cast-in-place pile are subjected to early-warning analysis and determined by means of datafied languages, and accurate and reliable data support is provided for later processing of a defective pile.
