AI Technical Summary
During tunnel construction, the unevenness of the inner wall of the surrounding rock causes the surrounding rock monitoring equipment to tilt during installation, affecting the angle of the emitted light pattern and thus the accuracy of the surrounding rock monitoring.
A high-precision tunnel surrounding rock monitoring device is adopted, which utilizes a fixing component including a spherical base, a rotating inner spherical shell, a locking claw, a threaded ring, and a pressure tube, and is fixed by expansion screws. By adjusting the position of the base plate and rotating the rotating knob ring, the claw plate is made to fit tightly against the outer periphery of the expansion screw, thus achieving installation and fixing without contact with the surrounding rock.
This reduces the impact of uneven surrounding rock on the angle of the emitted light pattern of the monitoring equipment, thus improving the installation stability and measurement accuracy of the monitoring equipment.
