[0003] In the face of this situation, surveyors often use the method of visual inspection to adjust the level of the sensor. Obviously, this visual positioning method has great randomness, or it cannot guarantee the horizontal arrangement of the sensor at all, and thus cannot meet the vibration measurement requirements of the sensor itself, affecting the measurement.

The embodiment of the invention provides a tunnel arch blasting vibration sensor mounting method, and relates to the technical field of tunnel blasting vibration measurement. The method comprises thesteps: a blasting vibration sensor is preliminarily arranged on the rock wall of a tunnel arch, the face, with a direction mark, of the blasting vibration sensor faces upwards, and the X direction points to the axial direction of a tunnel, namely the blasting source direction; electronic equipment with functions of a compass and a gradienter and a display screen is prepared, such as a smart phone,and the back surface of the electronic equipment is tightly attached to the bottom surface of the blasting vibration sensor; the gradienter and the compass are displayed in the same interface, and the gradienter is arranged in the center of the compass in a floating mode; and when the center of the gradienter on the display screen coincides with the center of the compass, the blasting vibration sensor is finally fixed. The sensor is ensured to be in a true horizontal state.
Description
technical field [0001] The invention relates to the technical field of tunnel blasting vibration measurement, in particular to a method for installing a blasting vibration sensor in a tunnel arch. Background technique [0002] With the deepening of the research on tunnel blasting vibration measurement technology, there are more and more experimental studies on the vibration effect of the tunnel arch. However, the principle of the blasting vibration sensor requires that its Z direction must point to the vertical direction, that is, the direction of the sensor must be tight. It is attached to the tunnel arch, which makes it impossible to provide effective installation and positioning assistance to the surveyors even if the sensor itself has its own leveling air bubbles. [0003] In the face of this situation, surveyors often use the method of visual inspection to adjust the level of the sensor. Obviously, this visual positioning method has great randomness, or it cannot guaran...
