Description

Technical Field

[0001] The utility model relates to the technical field of tunnel monitoring, in particular to a monitoring device for tunnel engineering. Background Technique

[0002] During tunnel construction, due to the complexity of the surrounding geological conditions and the continuous change of rock and soil mechanical behavior during the construction process, etc., it will have a comprehensive impact on the tunnel, resulting in the deformation of the tunnel. Therefore, the monitoring and measurement of the tunnel is an important link in the safety control of tunnel construction. Tunnel deformation is the most intuitive external reflection of the change of its internal mechanical behavior. When monitoring the deformation of the tunnel structure during tunnel construction, the safety of the project construction can be guaranteed. After the tunnel is excavated, the rock mass ruptures and forms a relaxed state, and it may collapse at any time. Therefore, it is necessary to detect the mechanical forms of the surrounding rock and the support structure. The convergence of the clearance and the settlement of the crown are the most direct and obvious reflections. For in-tunnel monitoring, due to site limitations, at present, total stations and deformation monitoring devices are mainly used to measure the convergence of the clearance and the settlement of the crown of the tunnel. This monitoring method is relatively simple to operate.

[0003] For example, the patent document with the publication number of CN219301588U discloses a new type of monitoring device for tunnel engineering construction deformation, including a tunnel. A fixing mechanism is installed on the top of the tunnel. The lower end of the fixing mechanism is connected to a receiving shell. A limiting rod is fixedly arranged on one side inside the receiving shell. A connecting plate is slidably arranged on the limiting rod. A reflecting prism is installed on the connecting plate. A through hole is opened at the bottom of the receiving shell. A cleaning mechanism is installed inside the receiving shell above the through hole. In the utility model, by rotating the first lead screw, the connecting plate drives the reflecting prism to descend. At this time, through the meshing of the driving wheel and the gear ring, the annular sleeve rotates. When the reflecting prism descends into the annular sleeve, the brush bristles clean the reflecting prism. Therefore, the surface of the reflecting prism can be cleaned when the reflecting prism moves out of or into the receiving shell, maintaining the reflection effect of the reflecting prism.

[0004] However, in the above-mentioned prior art, the reflecting prism is exposed for a long time. Not only will a lot of dust adhere to its surface, but also when the vehicle is driving, the crushed stones will fly due to being run over, and the flying crushed stones, etc. will damage the reflecting prism, shortening the service life of the reflecting prism. Therefore, a new monitoring device for tunnel engineering is proposed to optimize the above-mentioned prior art. Content of the Utility Model

[0025] By driving the threaded rod 9 through the driving motor 10, and with the cooperation of the threaded sleeve 8, the cover 5 can be lifted or lowered along the sliding direction of the guide sleeves 6 and the guide rods 7. Thus, the cover 5 can be lifted during use to expose the reflecting prism 4, and the cover 5 can be lowered when not in use to isolate the reflecting prism 4, effectively avoiding the situation of damage and dust accumulation on the reflecting prism 4 in daily life.

[0026] Barbs 11 are uniformly and fixedly connected to the outside of the pre-embedded anchor rod 1. Through the arrangement of the barbs 11, the fixing stability of the pre-embedded anchor rod 1 is increased, effectively achieving an anti-disconnection effect.

[0027] The end of the pre-embedded anchor rod 1 is fixedly connected with a ball head 12. A ball seat 13 adapted to it is movably sleeved on the ball head 12. The mounting seat 2 is fixedly connected to the ball seat 13. First threaded turning handles 14 are symmetrically threadedly connected to the ball seat 13. The first threaded turning handles 14 are inserted into the ball seat 13 and abut against the ball head 12. Threaded holes for threaded connection of the first threaded turning handles 14 are formed on the ball seat 13.

[0028] Through the ball head 12 and the ball seat 13, the pre-embedded anchor rod 1 and the mounting seat 2 are movably installed. With the tightening and fixing of the first threaded turning handles 14 and the non-slip rubber pads 15, the connection between the mounting seat 2 and the pre-embedded anchor rod 1 can be adjusted in all directions, thus facilitating the adjustment of the angle orientation of the reflecting prism 4.

[0029] The reflecting prism 4 is fixedly connected to the inner side of the top of the frame body 16. The bottom of the frame body 16 is inserted into the placement groove 3 and is in sliding fit with the placement groove 3. Fixed slots 17 are symmetrically arranged on both sides of the bottom of the frame body 16. A fixed insertion block 18 adapted to it is inserted into one of the fixed slots 17, and the fixed insertion block 18 is fixedly connected to the corresponding inner wall of the placement groove 3. An active insertion block 19 adapted to it is inserted into the other fixed slot 17. The active insertion block 19 is fixedly connected to the push plate 20.

[0032] The working principle of the present utility model is:

[0033] During use, the embedded anchor bolt 1 is inserted into the tunnel side wall and forms a stable fixation through the cooperation of the barbs 11. At this time, the frame body 16 is inserted into the placement groove 3 and cooperates with the fixed insertion block 18, so that the fixed insertion block 18 is inserted into the corresponding fixed slot 17. The second threaded turning handle 21 is further rotated, so that the push plate 20 abuts against the frame body 16, and at the same time, the active insertion block 19 is inserted into the corresponding fixed slot 17, so that the frame body 16 is fixed, and thus the reflecting prism 4 is installed. At this time, the angle orientation of the reflecting prism 4 is adjusted through the cooperation of the ball head 12 and the ball seat 13, and the first threaded turning handle 14 is further rotated, so that the anti-slip rubber pad 15 abuts against the ball head 12 to form a fixing effect. During use, the driving motor 10 can drive the threaded rod 9, and through the cooperation of the threaded sleeve 8, the cover 5 can be lifted along the sliding direction of the guide sleeve 6 and the guide rod 7, so that the cover 5 can be lifted during use to expose the reflecting prism 4, and the cover 5 can be lowered when not in use to isolate the reflecting prism 4, thus effectively avoiding the situation that the reflecting prism 4 is damaged and covered with dust in daily life.
