When installing, the staff can climb to the position of the TBM trolley for installation, but as the working face advances, the TBM gradually moves forward, resulting in a relative displacement between the position of the trolley and the position of the vault sensor after a period of time, causing the installation The final sensor cannot be recycled due to its height, causing property damage
In addition, for the sake of safety, the tunnel construction will carry out mortar spraying treatment. Due to monitoring needs, the sensor installation process is before the spraying of the construction unit, resulting in some sensors being damaged due to the pressure of the spraying, or due to the thickness of the spraying. Larger, the sensor is buried by the mortar and cannot be recovered, resulting in the failure of the microseismic monitoring equipment to continue to work normally, affecting the monitoring effect, and further causing property losses

The invention provides a dual-protection micro-seismic monitoring sensor assembly, which is characterized in that the sensor assembly is fixed in a shell through a first supporting base, the shell is anchored on a free face in a tunnel through an anchoring sheet, the anchoring sheet is slidably connected with the shell, one end of the shell is provided with a hooking and pulling ring, and the shell comprises a first shell and a second shell of which one ends are hinged; and the movable end of the first shell and the movable end of the second shell are each provided with a semicircular body, the two semicircular bodies are matched to form a screw rod, the shell further comprises a cylindrical nut screwed on the screw rod, the semicircular bodies are arranged on the sides, close to the free face in the tunnel, of the first shell and the second shell, and the sensor assembly comprises a shell with a containing space and a sensor. The sensor is accommodated in the accommodating space. The invention also provides a mounting and dismounting method of the micro-seismic monitoring sensor assembly with dual protection. According to the invention, through the sliding connection of the shell and the anchoring sheet, the sensor assembly can be conveniently recovered, and the shell and the shell play a dual protection role.
Description
technical field [0001] The invention relates to the technical field of underground engineering, in particular to a dual-protection microseismic monitoring sensor assembly and its installation and removal methods. Background technique [0002] When the microseismic monitoring equipment is installed in the tunnel, in order to ensure all-round signal reception, the sensors must be installed in a scattered distribution, so some sensors need to be installed at the spandrel or vault position of the tunnel. When installing, the staff can climb to the position of the TBM trolley for installation, but as the working face advances, the TBM gradually moves forward, resulting in a relative displacement between the position of the trolley and the position of the vault sensor after a period of time, causing the installation The final sensor cannot be recycled due to its height, resulting in property damage. In addition, for the sake of safety, the tunnel construction will carry out morta...
