AI Technical Summary
The GNSS antennas of existing GNSS monitoring stations are prone to tilting during installation, and the adjustment process is complex and cumbersome, requiring tools and affecting monitoring accuracy and efficiency.
A GNSS installation device for monitoring the displacement of buildings during subway construction is designed. It adopts an adjustment mechanism, including a mounting plate, a ball joint, a connecting rod, a slider, a disc, and a locking assembly. The horizontal level of the mounting plate is adjusted by sliding the slider on the disc, simplifying the adjustment process.
It enables rapid and easy leveling of GNSS antennas, improves monitoring accuracy and stability, and is suitable for real-time data transmission in complex environments. It is applicable to engineering fields such as subway construction, bridge health monitoring, and landslide early warning.
