[0022] The sides of the fan-shaped groove plate 5 and the fan-shaped slide plate 7 together form a plug plate; the support plate 1 preferably uses an arc plate with a similar arc profile to the inner wall of the tunnel. The tunnel lining trolley plug plate installation auxiliary system completes the construction of the plug plate through mechanical equipment, and controls the synchronous extension of each pusher 8 so that each fan-shaped slide plate 7 can slide out of the corresponding fan-shaped groove plate 5 until the fan-shaped slide plate 7 abuts the tunnel wall, and then connects the two adjacent fan-shaped slide plates 7 and the two fan-shaped groove plates 5 through the first elastic water stop 4, avoiding the occurrence of leakage, structural hollowing and voids, and structural deformation during concrete pouring, and ensuring the quality of the project; the tunnel lining trolley plug plate installation auxiliary system is faster and more standardized in installing the plug plate, saving a lot of manpower, material and financial resources, speeding up construction efficiency, and avoiding the problem of rework.

[0024] The telescopic amount of the telescopic member 9 is controlled so that the telescopic member 9 can push the fan-shaped groove plate 5 to rotate around the support plate 1, thereby changing the angle between the fan-shaped groove plate 5 and the support plate 1. At the same time, the telescopic amount of the telescopic member 9 can be adjusted according to the actual slope of the inner wall of the tunnel so that the plate surface of the fan-shaped groove plate 5 is perpendicular to the slope of the inner wall of the tunnel to increase the blocking effect.

By adjusting the multiple fan-shaped groove plates 5 in each plugging plate assembly 3 and rotating them to a suitable angle, the end of the fan-shaped groove plate 5 can be more closely fitted to the inner wall of the tunnel.

[0027] In this embodiment, Figure 3 and Figure 6-Figure 7 A groove 11 is provided on the end surface of the sector slide plate 7 opposite to the bottom wall of the slide groove 6 , and the pusher 8 extends into the groove 11 and is connected to the top surface of the groove 11 .

[0028] The relative distance between the fan-shaped slide plate 7 and the fan-shaped slot plate 5 can be reduced, and the height distance between the fan-shaped slide plate 7 and the fan-shaped slot plate 5 is reduced without changing the actual length and telescopic length of the pusher 8 .

[0029] In this embodiment, Figure 3 The upper surface of the end of the support plate 1 is fixedly connected to the lower surface of the steel mold 2 . When the telescopic member 9 is extended, the plate surface of the fan-shaped groove plate 5 can be made vertical, and the plate surface of the fan-shaped groove plate 5 abuts against the end surface of the steel mold 2 .

[0032] The distance between the support plate 1 and the end of the steel mold 2 is 30-50cm. The trolley steel beam 12 is the supporting point of the trolley jack on the steel mold. It has high strength and the trolley jack is required to support the trolley steel beam 12 from below when in use. At the same time, a triangular steel frame 13 is provided between the trolley steel beam 12 and the support plate 1 to prevent the end of the steel mold 2 from being deformed due to high pressure during the pouring process.

[0033] In this embodiment, Fig. 9 The pushing member 8 is a hydraulic telescopic rod, and the telescopic member 9 is a hydraulic diagonal support rod. The hydraulic telescopic rod and the hydraulic diagonal support rod are both controlled by independent cylinder controllers, and each independent cylinder controller is connected to the intelligent control platform by signal.

[0034] In this embodiment, Figure 8-Figure 9 The upper end surface of the fan-shaped skateboard 7 is provided with an elastic pad 14, a distance sensor 15 and a pressure sensor 16, and the distance sensor 15 and the pressure sensor 16 are embedded in the elastic pad 14; the distance sensor 15 and the pressure sensor 16 are both connected to the intelligent control platform by signal, and the intelligent control platform sends the distance value measured by the distance sensor 15 and the pressure value measured by the pressure sensor 16 to the remote terminal in real time, and the intelligent control platform sends an action instruction to the corresponding independent cylinder controller according to the signal sent by the remote terminal, so that the independent cylinder controller controls the corresponding pushing member 8 and telescopic member 9 to move, thereby completing the installation of the plug plate in the tunnel.

[0035] The elastic pad 14 is made of rubber material, and the fan-shaped skateboard 7 squeezes the elastic pad 14 to fit the tunnel wall. The elastic pad 14 is deformed and has a higher fit with the tunnel wall, which plays a better anti-blocking role. The hydraulic telescopic rod and the corresponding independent cylinder controller constitute the plugging plate height adjustment system, and the hydraulic diagonal support rod and the corresponding independent cylinder controller constitute the plugging plate angle adjustment system. The plugging plate height adjustment system and the plugging plate angle adjustment system are controlled by the intelligent control platform at the same time, so that the plugging plate can be set up at different heights and different inclination angles, ensuring the quality and quantity of the secondary lining and the standardized casting completion.

[0036] An operating method for a tunnel lining trolley plugging plate installation auxiliary system comprises the following steps: S100, control the template trolley to enter the predetermined location of the tunnel; the operator inputs the pressure threshold and the distance threshold on the remote terminal, starts the intelligent control platform, and the intelligent control platform controls the multiple plugging plate components 3 to act simultaneously; S200, the intelligent control platform controls each telescopic member 9 to synchronously extend a specific distance so that the plate surface of each of the fan-shaped slot plates 5 rotates to a set angle; S300, the distance measuring sensor 15 on the top of each fan-shaped slide plate 7 detects the distance from the tunnel wall in real time, and feeds back the detected distance data to the intelligent control platform, and the intelligent control platform further controls each pusher 8 to extend simultaneously according to the received data, until the pressure value detected by the corresponding pressure measuring sensor 16 received by the intelligent control platform reaches the set threshold value, indicating that the corresponding fan-shaped slide plate 7 completes the blocking of the tunnel side wall, and the intelligent control platform controls the corresponding pusher 8 to stop extending and maintain the already extended length; S400: The intelligent control platform receives that the pressure values ​​detected by all the pressure measuring sensors 16 have reached the set threshold value, indicating that all the fan-shaped slide plates 7 have completed the blocking of the tunnel side wall, and the blocking operation of the tunnel plugging plate is completed at this time; S500, perform pouring operation. After completion, the system enters the pressure maintaining state until the mold is removed.

[0037] In the present embodiment, in step S200, the intelligent control platform sends an extension instruction to the independent cylinder controllers corresponding to each telescopic member 9, and then the corresponding independent cylinder controllers control each telescopic member 9 to synchronously extend a specific distance.

[0038] This device and operation method rely on the use of secondary lining formwork trolleys. Relevant technicians determine the relevant parameters, and then send commands through the remote terminal. The plugging plate angle adjustment system controls the plugging plate to rotate to the set angle, and then the distance to the tunnel wall is measured by the distance sensor 15 (the height can also be set independently), and the feedback is fed back to the smart platform. The smart platform will control the plugging plate height adjustment system through the received information; at the same time, when the pressure value detected by the top pressure sensor 16 reaches the set threshold, it indicates that the plugging plate has been completely blocked; after the pouring is completed, this system can enter the pressure holding state until the formwork is removed; thereby realizing the tilting of the plugging plate at any angle and the adjustment of any height, and ensuring complete blocking.
