The invention discloses an optical detector for the structural stability of the surrounding rock of a tunnel, relates to the technical field of surrounding rock state monitoring, and comprises a mounting frame and a sliding sleeve. The top of the mounting frame is provided with two bolt mounting holes. The mounting frame Two connecting blocks are installed at the bottom of the sliding sleeve, and a rack mounting hole is opened on the side of the sliding sleeve. Pull the operation block outward, drive the limit lever to release the limit on the positioning block, then push the sliding sleeve to move left and right, adjust the horizontal position of the sliding sleeve, so that the positioning block moves up and down continuously, when adjusted to a suitable position Finally, loosen the operation block, under the tension of the tension spring, the limit rod resets into the limit groove, and then the sliding sleeve is limited and fixed, and the installation ring can be rotated through the setting of the damping sleeve, and the installation ring The angle is adjusted to realize the adjustment of the installation position of the scale. Even if there is a slight deviation in the position when drilling, there is no need to re-drill and install, which enhances the practicability of the device.
Description
technical field [0001] The invention relates to the technical field of surrounding rock state monitoring, in particular to an optical detector for structural stability of surrounding rock of a tunnel. Background technique [0002] During the excavation of highway tunnels, poor surrounding rock conditions such as weak, loose, swollen or fault fracture zones are often encountered. In the monitoring of the displacement of the surrounding rock of the tunnel, monitoring the displacement of the top of the section is the most important. The traditional monitoring method is A hanging ring is set on the top of the monitoring section, and a ruler is hung on the hanging ring. The ruler suspended at the point to be measured is irradiated by a laser emitting device, and the monitoring data is obtained through the change of the position of the light spot on the ruler. A set of photosensitive sensors are arranged on the ruler. , which can realize remote monitoring of data, and the monitori...
