[0002] A tunnel project is a structure built underground, underwater or in a mountain to lay railways or build roads for motor vehicles to pass through.

[0003] After searching, the patent document with announcement number CN116399293B is as follows: A system and method for monitoring the settlement and deformation of an operating tunnel, including an arched slide rail, a symmetrical L-shaped slider slidingly arranged on the upper crossbeam of the arched slide rail, and a support box is arranged on the top surface of the symmetrical L-shaped slider, and a support bar is slidably inserted inside the support box, and a sliding plate is connected to the lower surface of the symmetrical support bar, and a contact roller is rotatably arranged between the upper end surfaces of the symmetrical support bar, and a pin column is installed on the lower surface of the sliding plate, and the pin column slides out to the lower surface of the support box, and a contact pressure plate is arranged on the upper surface of the upper crossbeam of the arched slide rail, and the upper surface of the contact pressure plate contacts the lower end surface of the pin column, and a pressure sensor is arranged between the lower surface of the contact pressure plate and the mounting groove; the monitoring personnel of the present invention judge the settlement and deformation monitoring of a certain or local surrounding rock based on the data transmitted by the pressure sensor, so as to facilitate the construction personnel to repair the settlement position of the tunnel arch top surface in time.

[0015] Compared with the prior art, the present invention has the following advantages: 1. By setting up structures such as a sliding frame, an electric slider and a monitoring mechanism, the sliding frame can move a certain distance along the direction of the tunnel each time, and then the electric slider drives the monitoring mechanism to move back and forth in the horizontal direction along the sliding frame, thereby automatically monitoring the settlement conditions at different positions of the tunnel; 2. When monitoring the settlement of the top wall inside the tunnel, the electric slider drives the monitoring block to move rightward on the slide frame, and the monitoring roller rotates in contact with the top wall inside the tunnel. When the top wall inside the tunnel may settle, the monitoring roller will move downward for a short distance. By setting structures such as a U-shaped plate, multiple gears and multiple racks, the small displacement of the monitoring roller moving downward is amplified multiple times to avoid the monitoring mechanism from finding the small settlement in time. The conductive column will slide downward against the side wall of the resistor, so that the alarm reaches the working voltage, generates an alarm and automatically records the possible tunnel settlement here; 3. False alarms may also occur when impurities such as mud adhere to the top wall of the tunnel or impurities adhere to the roller of the monitoring roller. In the above process, the U-shaped plate and the second long strip are moving downward. Since the second long strip moves faster, the distance between the U-shaped plate and the second long strip will continue to increase. By setting structures such as sliding plugs, connecting rods and brushes, the brush and the roller of the monitoring roller are in contact with each other, and the surface of the monitoring roller is brushed to remove impurities. Then, the cleaning liquid will be sprayed from the nozzle through the connecting pipe to wash the surface of the monitoring roller, so as to avoid false alarms of the settlement of the top wall of the tunnel caused by impurities adhering to the monitoring roller; 4. When the monitoring roller moves downward for a long distance, the wedge plate drives the wedge block to slide to the right for a distance through the wedge hole and disengages from the slot. Under the action of the tension spring, the sliding rack slides upward for a distance, and then the sliding rack drives the scraper to contact the top wall inside the tunnel. Then the electric slider drives the scraper to move left and right repeatedly on the top wall inside the tunnel through the monitoring block and other structures, so that the scraper scrapes against the top wall inside the tunnel. If there are impurities such as mud on the top wall inside the tunnel, they can be scraped off, and then the monitoring roller is re-monitored; 5. If the top wall of the tunnel is not a false alarm caused by impurities such as soil, then the top wall of the tunnel has experienced a large settlement. At this time, there is a safety hazard at the settlement of the top wall of the tunnel. During the upward movement of the sliding rack, the bottom end of the support plate is in contact with the ground inside the tunnel by setting structures such as transmission gears, spur racks and support plates, and the electrorheological fluid inside the rubber sleeve is energized. The electrorheological fluid changes from liquid to solid, and then forms a hard body inside the rubber sleeve, forming a stable triangular structure with the support plate, which can partially support the top wall of the tunnel for subsequent maintenance personnel to perform inspection and maintenance.

[0021] A liquid storage tank 45 is fixedly connected to the side wall of the monitoring block 1, and the liquid storage tank 45 is filled with cleaning liquid. A one-way liquid inlet pipe 29 and two one-way liquid outlet pipes 30 are fixedly connected to the inner wall of the sliding cavity 26. The other end of the one-way liquid inlet pipe 29 passes through the inner wall of the rectangular block 4 and is fixedly connected to the liquid storage tank 45. The other end of the one-way liquid outlet pipe 30 passes through the inner wall of the rectangular block 4 and is fixedly connected to the inner wall of a corresponding slide groove 32.

[0022] The lifting mechanism also includes a rectangular groove 22 opened on the top wall of the monitoring block 1, a sliding rack 24 is slidably connected to the inner wall of the rectangular groove 22, a scraper 25 is fixedly connected to the top of the sliding rack 24, the bottom end of the sliding rack 24 is elastically connected to the inner wall of the rectangular groove 22 through a tension spring 23, a wedge block 20 is slidably connected to the side wall of the rectangular groove 22, the other end of the wedge block 20 extends into the interior of the cavity 5, a wedge hole 21 is opened on the side wall of the other end of the wedge block 20, and a slot 46 is opened on the side wall of the sliding rack 24.

[0023] The bottom wall of the second long strip 16 is fixedly connected to the wedge plate 13 , and the wedge plate 13 and the inner wall of the wedge hole 21 are inserted and slidably matched with each other without separation, and one end of the wedge block 20 is inserted into the slot 46 .

[0024] The inner wall of the monitoring block 1 is provided with a T-shaped groove 39 connected to the inner wall of the rectangular groove 22, and the inner wall of the T-shaped groove 39 is slidably connected with a straight rack 41, and the inner wall of the T-shaped groove 39 is rotatably connected with a transmission gear 40, the transmission gear 40 is meshed with the sliding rack 24, the transmission gear 40 is meshed with the straight rack 41, and the bottom wall of the straight rack 41 is fixedly connected with a rubber sleeve 42, and the side wall of the monitoring block 1 is fixedly connected with an L-shaped frame 43, and the inner wall of the L-shaped frame 43 is rotatably connected with a support plate 44, and one end of the rubber sleeve 42 away from the straight rack 41 is fixedly connected to the support plate 44, and the inner wall of the rubber sleeve 42 is fixedly connected with the support plate 44. The electrorheological fluid is filled with electrorheological fluid, which is composed of solid particles with high dielectric constant and silicone oil with low dielectric constant. It can transform from liquid to solid under the action of electric field. When the external electric field strength is much lower than a certain critical value, the electrorheological fluid is liquid; when the electric field strength is much higher than this critical value, it becomes solid; electrorheological fluid can produce obvious electrorheological effect under the action of electric field, that is, it can quickly and reversibly transform between liquid and quasi-solid state, or between fluid state (quasi-liquid state) and solid state, and maintain continuous viscosity. This transformation is extremely rapid, instantaneous and controllable, with extremely low energy consumption, and can achieve real-time control.

[0025] The first rack 10 is meshed and connected with the first gear 8 , the third rack 12 is meshed and connected with the first gear 8 , the second rack 15 is meshed and connected with the second gear 31 , and the fourth rack 17 is meshed and connected with the second gear 31 .

[0026] The conductive column 18, the resistor 47 and the alarm 19 are electrically connected. The slide frame 3 is an inverted cross structure. The bottom wall of the slide frame 3 is symmetrically fixedly connected with an electric pulley 49. The electric pulley 49 and the electric slider 2 are both existing technologies and will not be described in detail here.

[0027] The electric slider 2 is slidably fitted on the side wall of the slide frame 3, the electric slider 2 is fixedly connected to the monitoring block 1, and a tension spring (such as Figure 8 As shown), the other end of the tension spring is fixedly connected to the inner wall of the cavity 5.

[0028] In the present invention, the frame track at the top of the slide frame 3 is consistent with the track of the top wall inside the tunnel. The electric slider 2 can reciprocate horizontally along the slide frame 3, and the electric pulley 49 can drive the slide frame 3 to move a certain distance along the direction of the tunnel each time, thereby automatically monitoring the settlement conditions at different positions of the tunnel.

[0029] When monitoring the settlement of the top wall inside the tunnel, the electric slider 2 is turned on, and the electric slider 2 drives the monitoring block 1 to move to the right on the slide frame 3. Since the roller portion of the monitoring roller 7 is in contact with the top wall inside the tunnel, the monitoring roller 7 will rotate in contact with the top wall inside the tunnel during the movement with the monitoring block 1. When the top wall inside the tunnel may settle, the monitoring roller 7 will move downward for a short distance, and the monitoring roller 7 will drive the C-shaped plate 6 to move downward for a short distance, and the C-shaped plate 6 will drive the first gear 8 to move. Since the first gear 8 is respectively meshed with the first rack 10 and the third rack 12, the third rack 12 will drive the third rack 12 to move. A long strip block 11 moves downward at a double stroke, and under the action of the second gear 31 and the second rack 15, the second gear 31 drives the second long strip block 16 to move downward at a double stroke through the fourth rack 17, thereby amplifying the tiny displacement of the monitoring roller 7 downward by multiple times, so as to avoid the monitoring mechanism from having difficulty in timely detecting tiny settlements. Then, the conductive column 18 fixedly connected to the side wall of the second long strip block 16 will slide downward against the side wall of the resistor 47, so that the resistance in the circuit formed by the resistor 47, the conductive column 18 and the alarm 19 will continue to decrease until the alarm 19 reaches the working voltage, generates an alarm and automatically records the possible tunnel settlement here.

[0030] When there are impurities such as mud adhering to the top wall of the tunnel or impurities adhering to the roller part of the monitoring roller 7, false alarms may occur. In the above process, the U-shaped plate 6 and the second long block 16 move downward. Since the second long block 16 moves faster, the distance between the U-shaped plate 6 and the second long block 16 will continue to increase. Then the connecting rod 28 fixedly connected to the inner wall of the U-shaped plate 6 will drive the sliding plug 27 to slide in the sliding cavity 26 through the one-way liquid outlet pipe 30. The cleaning liquid squeezed into the two chutes 32 will push the slide plate 33 to slide upward for a certain distance, and the slide plate 33 will drive the support column 36 to move upward for a certain distance, so that the brush 38 and the roller part of the monitoring roller 7 are in contact with each other, and the surface of the monitoring roller 7 is brushed to remove impurities. Then the cleaning liquid will be sprayed out from the nozzle 37 through the connecting pipe 35 to rinse the surface of the monitoring roller 7, so as to avoid the impurities adhering to the monitoring roller 7 and causing false alarm of the settlement of the top wall inside the tunnel.

[0031] When the monitoring roller 7 moves downward for a long distance, it indicates that the possible settlement is serious and there is a safety hazard. It is necessary to eliminate other false alarms. Then, the second long block 16 moves downward for a long distance and drives the wedge plate 13 to move synchronously, so that the wedge plate 13 drives the wedge block 20 to slide to the right for a distance (such as 20) through the wedge hole 21. Figure 3 and Figure 4 As shown), the wedge block 20 can be released from the limit release state from the slot 46, and the sliding rack 24 can slide upward for a distance under the action of the tension spring 23, so that the sliding rack 24 will drive the scraper 25 to contact the top wall inside the tunnel. Then the electric slider 2 drives the scraper 25 to move left and right repeatedly on the top wall inside the tunnel through the monitoring block 1 and other structures, so that the scraper 25 scrapes the top wall inside the tunnel. If there are impurities such as soil on the top wall inside the tunnel, they can be scraped off, and then the monitoring roller 7 is ordered to re-monitor.

[0032] If the top wall of the tunnel is not a false alarm caused by impurities such as soil, then the top wall of the tunnel has a large settlement. At this time, there is a safety hazard at the settlement of the top wall of the tunnel. During the upward movement of the sliding rack 24 (such as Figure 3 As shown in the figure, the sliding rack 24 will drive the transmission gear 40 meshing with it to rotate, and the transmission gear 40 will drive the spur rack 41 meshing with it to move downward for a distance, then the spur rack 41 will drive the rubber sleeve 42 to move downward, and since the other end of the rubber sleeve 42 is fixedly connected to the support plate 44, the user can pull the support plate 44 to rotate it (as shown in the figure). Figure 2 As shown), until the bottom end of the support plate 44 contacts the ground inside the tunnel, at which time the rubber sleeve 42 will be stretched and deformed, and then the electrorheological fluid inside the rubber sleeve 42 is energized, and the electrorheological fluid changes from liquid to solid, thereby forming a hard body inside the rubber sleeve 42, and forming a stable triangular structure with the support plate 44, thereby partially supporting the top wall inside the tunnel, waiting for subsequent maintenance personnel to perform maintenance.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
