Description

Technical Field

[0001] This invention belongs to the field of shield tunnel grouting technology, specifically a TBM rapid construction grouting device. Background Technology

[0002] TBM (Tunnel Boring Machine) construction methods have been widely applied in tunnel construction. However, TBM construction also faces the high risk of segment misalignment, cracks, and water leakage, bringing a series of difficulties and challenges to TBM construction. During TBM excavation, the excavation diameter of the cutterhead and shield is usually slightly larger than the ring diameter of the segments. Therefore, if the bottom of the segments is not filled in time when they leave the shield tail, the segments will sink under gravity, leading to irreversible changes in the tunnel alignment and posing a serious risk to construction safety. TBM tunnel grouting is achieved by using the hoisting hole in the center of the segment and the supporting grouting system to fill the gravel pores in the annular gap between the segments and the surrounding rock after the segments have left the shield tail.

[0003] A patent application with publication number CN118462233A discloses a grouting device for TBM tunnel construction, which adopts an automatically telescopic grouting pipe that can automatically adjust its length according to the shape of the tunnel cross section, making the grouting operation more convenient and efficient.

[0004] While the above-mentioned technical solution solves the problem of relying on traditional welding and sealing grouting methods and significantly reduces the manpower and time costs in the construction process, simply inserting the grouting pipe into the predetermined position and relying entirely on the self-flow and pressure of the grout to penetrate into the voids of the crushed stone layer has significant risks and limitations. Due to the looseness and heterogeneity of the crushed stone layer itself, the supporting force of the crushed stone on the tunnel segments in the dispersed state is relatively weak. The internal voids are of varying sizes and unevenly distributed, causing the grout to encounter great resistance during the flow process, making it impossible to uniformly and fully fill all voids, thus affecting the overall effect of grouting reinforcement. If the grouting is insufficient or ineffective, it will further weaken this supporting effect. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 7As shown in the embodiment of the present invention, a TBM rapid construction grouting device includes a mounting housing 1. A swing grouting assembly is installed inside the mounting housing 1. The swing grouting assembly includes four conveying grouting components and a swing drive assembly. The swing grouting assembly drives the four conveying grouting components to swing through the swing drive assembly. Each of the four conveying grouting components includes an inlet pipe 2 and a outlet pipe 3. The conveying grouting components input grout through the inlet pipe 2 and discharge grout through the outlet pipe 3. The swing drive assembly includes a first magnet plate 4, a second magnet plate 5, and a third magnet plate 6. The swing drive assembly drives the third magnet plate 6 to reciprocate by rotating the first magnet plate 4 and the second magnet plate 5. During operation, the mounting housing 1 is first installed on the TBM by welding. On the outside of the TBM shield 33, during the moving construction of the TBM shield 33, the installation casing 1 can be moved simultaneously. Grouting is then carried out between the tunnel inner wall and the shield segments through the grouting assembly to form a stable grouting layer. In addition, the swing drive assembly can rotate the first magnet plate 4 and the second magnet plate 5 to drive the third magnet plate 6 to move back and forth, thereby driving the grout discharge pipe 3 of the grouting assembly to move back and forth. This adjusts the position of the grout outlet of the grout discharge pipe 3, ensuring that the grouting outlet can cover most of the grouting area. This ensures that the grouting material is evenly distributed in the grouting area, avoiding quality problems such as voids and cracks caused by uneven grouting, and greatly improving the efficiency and safety of the grouting operation.

[0030] like Figures 1 to 6 As shown, the grouting assembly also includes a telescopic hose 7 and a connecting pipe 8. One end of the telescopic hose 7 is connected to one end of the grout inlet pipe 2, and the end of the telescopic hose 7 away from the grout inlet pipe 2 is connected to one end of the connecting pipe 8. The end of the connecting pipe 8 away from the telescopic hose 7 is connected to one end of the grout discharge pipe 3. An auxiliary grout outlet 9 is provided on the outside of the grout discharge pipe 3. During operation, a grout supply device can be connected to the grout inlet pipe 2 to supply grout to the grout inlet pipe 2. The grout inside the grout inlet pipe 2 will be transported to the inside of the grout discharge pipe 3 through the telescopic hose 7 and the connecting pipe 8. Then, the grout will be injected into the tunnel wall and between the shield segments through the grout discharge pipe 3. The auxiliary grout outlet 9 can assist in grout discharge, effectively assisting the grout outlet of the grout discharge pipe 3 in the uniform distribution and discharge of grout. It can also significantly improve the overall effect and efficiency of the grouting operation, avoid the accumulation of grout in the grout discharge pipe 3 or the formation of dead zones, and ensure that the grout can smoothly reach and penetrate into every corner of the grouting area.

[0031] like Figures 1 to 6As shown, four fixing boxes 27 are fixedly installed on the inner side of the mounting housing 1. The ends of the four slurry inlet pipes 2 that are connected to the telescopic hose 7 are respectively fixedly installed on the inner side of the fixing boxes 27. During operation, the function of the four fixing boxes 27 is to fix the four slurry inlet pipes 2, preventing the slurry inlet pipes 2 from being pulled and stretched in the opposite direction by the weight of themselves and the slurry transported inside them. On the one hand, this prevents the slurry inlet pipes 2 from moving around due to the extensibility of the telescopic hose 7 during use, which would affect the slurry delivery effect. On the other hand, it ensures that the telescopic hose 7 can only be pulled and stretched through the connecting pipe 8, ensuring the normal operation of the swing assembly.

[0032] like Figures 1 to 7 As shown, the swing assembly also includes a mounting circular plate 10. A drive motor 11 is fixedly mounted on one side of the mounting circular plate 10. The output end of the drive motor 11 movably passes through the mounting circular plate 10 and is fixedly mounted with a rotating column 12. Two connecting rods 13 are symmetrically fixedly mounted on the outer side of the rotating column 12. A mounting block 14 is fixedly mounted on the end of each connecting rod 13 away from the rotating column 12. A magnet plate 4 is fixedly mounted on the side of the mounting block 14 away from the connecting rods 13. During operation, after the mounting circular plate 10 is started, the output end of the mounting circular plate 10 can drive the rotating column 12 to rotate, thereby driving the connecting rods 13 to rotate, causing the mounting block 14 to rotate, and finally driving the magnet plate 4 to move. This provides the running power for the swing assembly, allowing the grout discharge pipe 3 to move, ensuring that the grouting port can cover most of the grouting area and that the grouting material is evenly distributed within the grouting area.

[0033] like Figures 1 to 7As shown, a drive gear 15 is fixedly mounted on the outer side of the rotating column 12. A driven gear 16 is rotatably mounted on the side of the mounting plate 10 away from the drive motor 11, and the outer sides of the drive gear 15 and the driven gear 16 mesh with each other. A transmission gear 17 is fixedly mounted on the side of the driven gear 16 away from the mounting plate 10. A rotating ring 18 is rotatably mounted on the side of the mounting plate 10 away from the drive motor 11. A toothed groove 19 is provided on the inner side of the rotating ring 18. The outer side of the transmission gear 17 meshes with the toothed groove 19 inside the rotating ring 18. Two connecting rods 20 are symmetrically fixedly mounted on the end of the rotating ring 18 away from the mounting plate 10. A mounting block 21 is fixedly mounted on the end of each connecting rod 20 away from the rotating ring 18. A magnet plate 5 is fixedly mounted on the side of the mounting block 21 away from the connecting rods 20. During operation, after the mounting plate 10 is started, the output end of the mounting plate 10 can rotate the rotating column 12, thereby causing the drive gear 15 to rotate. The driven gear 16 rotates, which in turn drives the transmission gear 17 to rotate. This, in turn, drives the rotating ring 18 to rotate through the meshing tooth groove 19, which in turn drives the connecting rod 20 to rotate. This causes the mounting block 21 to rotate, and finally drives the magnet plate 5 to rotate. The ratio of the number of teeth on the outer side of the driving gear 15 to the number of teeth on the outer side of the driven gear 16 is 2:1, meaning that the driven gear 16 rotates twice for the driving gear 15 to rotate once. The ratio of the number of teeth on the outer side of the transmission gear 17 to the number of tooth grooves 19 inside the rotating ring 18 is 1:2, meaning that the rotating ring 18 rotates once for the transmission gear 17 to rotate twice. This results in the rotating rod 12 rotating once and the rotating ring 18 rotating once. The rotation directions of the rotating rod 12 and the rotating ring 18 are opposite. In the initial state, the connecting rod 20 and the connecting rod 13 are perpendicular, and the connecting rod 20 and the connecting rod 13 will meet at positions of 45 degrees, 135 degrees, 225 degrees, and 315 degrees.

[0034] like Figures 1 to 7As shown, the swing assembly also includes mounting block three 22, magnet plate three 6 is fixedly mounted on one side of mounting block three 22, a moving block 23 is fixedly mounted on the side of mounting block three 22 away from magnet plate three 6, a moving rod 24 is fixedly mounted on one side of moving block 23, a moving ring 25 is fixedly mounted on the end of moving rod 24 away from moving block 23, and the moving ring 25 is fixedly mounted on the outside of the connecting pipe 8. The magnetic poles of magnet plate one 4 away from mounting block one 14 are the same as the magnetic poles of magnet plate two 5 and mounting block two 21, and opposite to the magnetic poles of magnet plate three 6 away from mounting block three 22. During operation, when mounting block one 14 passes the position of mounting block three 22, mounting block one 14 can utilize magnet plate one 4 and magnet plate three 22. The attraction between the magnets 6 drives the installation block 3 22 to move, which in turn drives the connecting pipe 8 to move through the moving block 23, moving rod 24 and moving ring 25, thus causing the grout discharge pipe 3 to move in one direction. When the installation block 21 passes the position of the installation block 3 22, the installation block 21 can use the attraction between the magnet plate 2 5 and the magnet plate 3 6 to drive the installation block 3 22 to move, which in turn drives the connecting pipe 8 to move through the moving block 23, moving rod 24 and moving ring 25, thus causing the grout discharge pipe 3 to move in another direction. This reciprocating movement of the grout discharge pipe 3 ensures that the grouting port can cover most of the grouting area and ensures that the grouting material is evenly distributed within the grouting area.

[0035] like Figures 1 to 5 As shown, four fixing rods 26 are symmetrically fixedly installed on the outer side of the mounting circular plate 10. The ends of the four fixing rods 26 away from the mounting circular plate 10 are respectively fixedly installed on one side of the four fixing boxes 27. During operation, the position of the mounting circular plate 10 can be fixed by the fixing rods 26 to ensure the normal use of the device.

[0036] like Figures 1 to 3 As shown, an arc-shaped groove is provided on one side of the mounting sleeve 1, and movable frame plates 28 are installed on both sides of the arc-shaped groove. Elastic shielding cloth strips 29 are fixedly installed on the outside of the connecting pipe 8. The end of the elastic shielding cloth strip 29 away from the inside of the arc-shaped groove is fixedly connected to both sides of the movable frame plate 28. When working, when the connecting pipe 8 moves, it can drive the elastic shielding cloth strip 29 to move inside the arc-shaped groove, and pull the movable frame plate 28 on the side opposite to the direction of movement to move, thereby sealing the arc-shaped groove and preventing the slurry discharged through the slurry discharge pipe 3 from backflowing into the interior of the mounting sleeve 1.

[0037] like Figures 1 to 4As shown, the interior of the mounting housing 1 has an annular groove 30. The magnet plate 6, mounting block 22, moving block 23, moving rod 24, and moving ring 25 are all located inside the annular groove 30. During operation, the magnet plate 6, mounting block 22, moving block 23, moving rod 24, and moving ring 25 can move inside the annular groove 30, thereby driving the grouting conveying assembly to move and ensuring the normal operation of the device.

[0038] like Figures 1 to 6 As shown, an installation ring 31 is fixedly installed on the outside of the connecting pipe 8. Both ends of the installation ring 31 are fixedly installed with combs 32, and the two combs 32 are located on both sides of the grout discharge pipe 3. When the connecting pipe 8 moves during operation, it can drive the installation ring 31 to move, thereby driving the combs 32 to move, so as to comb the large pieces of gravel between the tunnel inner wall and the shield segments, so that the large pieces of gravel accumulate at 45 degrees, 135 degrees, 225 degrees and 315 degrees. On the one hand, this prevents the large pieces of gravel from affecting the flow of grout and ensures the grouting effect. On the other hand, it can form four additional stable support areas in the grouting layer, improve the stability of the grouting layer, and thus construct a more compact and solid grouting structure.

[0039] Working principle: Grouting is supplied to the grouting pipe 2 via an external grouting device. The grout inside the grouting pipe 2 is then transported to the grouting discharge pipe 3 via a telescopic hose 7 and a connecting pipe 8. The grout is then injected into the tunnel wall and between the shield segments through an opening at one end of the discharge pipe 3 and an auxiliary grout outlet 9 on the side. Simultaneously, the installation circular plate 10 is activated. The output end of the installation circular plate 10 drives the rotating column 12 to rotate, which in turn drives the connecting rod 13 to rotate, causing the installation block 14 to rotate. Ultimately, this moves the magnet plate 4, and the rotating column... When the rotating column 12 rotates, it causes the driving gear 15 to rotate, which in turn drives the meshing driven gear 16 to rotate, and then drives the transmission gear 17 to rotate. This, in turn, drives the rotating ring 18 to rotate through the meshing tooth groove 19. Since the rotating column 12 and the rotating ring 18 rotate in opposite directions, this causes the connecting rod 20 to rotate, which in turn causes the mounting block 21 to rotate, ultimately driving the magnet plate 5 to rotate. When the mounting block 14 passes the position of the mounting block 22, the mounting block 14 can use the attraction between the magnet plate 4 and the magnet plate 6 to move the mounting block 22. The movement of the grout discharge pipe 3, via the moving block 23, moving rod 24, and moving ring 25, causes the connecting pipe 8 to move, thus moving the grout discharge pipe 3 in one direction. When the second mounting block 21 passes the position of the third mounting block 22, the second mounting block 21 can use the attraction between the second magnet plate 25 and the third magnet plate 6 to move the third mounting block 22, thereby causing the connecting pipe 8 to move via the moving block 23, moving rod 24, and moving ring 25, thus moving the grout discharge pipe 3 in the other direction. This reciprocating movement of the grout discharge pipe 3 ensures that the grouting port can cover the vast majority of the grouting area. The zoning ensures that the grouting material is evenly distributed within the grouting area. In addition, when the connecting pipe 8 moves, it can drive the installation ring 31 to move, which in turn drives the comb 32 to move, combing the large pieces of gravel between the tunnel inner wall and the shield segments, causing the large pieces of gravel to accumulate at 45 degrees, 135 degrees, 225 degrees and 315 degrees. On the one hand, this prevents the large pieces of gravel from affecting the flow of grout and ensures the grouting effect. On the other hand, it can form four additional stable support areas in the grouting layer, improving the stability of the grouting layer, thereby constructing a more compact and robust grouting structure.
