Description

Technical Field

[0001] This invention relates to the field of tunnel waterproofing technology, specifically to a waterproofing board with drainage grooves and its processing method. Background Technology

[0002] In the fields of tunnel, underground engineering, and building waterproofing, polymer waterproofing membranes (such as EVA, HDPE, and ECB waterproofing membranes) are widely used seepage prevention materials. Their traditional construction process is "nail-free installation," relying on their inherent impermeability to form a physical waterproof barrier. However, engineering practice shows that a single waterproofing membrane system relying solely on waterproofing functionality has the following inherent drawbacks: Traditional waterproofing membranes are laid directly against the surface of the initial support, serving only as a "water barrier." When the groundwater level is high or the water pressure is high, seepage water is blocked on the outside of the waterproofing membrane and cannot be effectively drained, easily forming localized "water pockets" between the waterproofing membrane and the initial support. These "water pockets" generate continuous hydrostatic pressure, which, over time, may cause cracks in the joints of the waterproofing membrane, penetration of weak points, or indirectly transfer water pressure to the secondary lining concrete, leading to cracking and leakage in the lining and threatening the long-term safety of the project. Therefore, a drainage membrane with drainage channels and its processing method are proposed. Summary of the Invention

[0014] This invention provides a drainage board with drainage grooves and its processing method, which has the following beneficial effects: 1. This drainage board with drainage grooves and its processing method, by setting drainage grooves on the outer side of the board, avoids the traditional method of waterproof boards being tightly attached to the initial support surface and only serving a water-proof function. When the groundwater pressure is high, water can easily accumulate behind the board, forming water pockets, which exert long-term hydrostatic pressure on the waterproof board, posing a risk of crushing or rupturing the joints. The drainage grooves on the outer side of the board form a continuous and organized drainage channel network. Groundwater can be first introduced into the grooves and then smoothly guided along the drainage grooves to the longitudinal drainage blind pipes on both sides of the tunnel, relieving water pressure and converting hydrostatic pressure into dynamic water flow, greatly reducing the risk of the waterproof layer being punctured.

[0015] 2. This invention relates to a drainage board with drainage grooves and its processing method. Traditional calendering or embossing machines have fixed patterns on their pressure rollers. To produce drainage boards with different drainage groove widths (groove spacing), the machine must be stopped and the entire set of pressure rollers or pressure heads replaced. This process is cumbersome, time-consuming, and labor-intensive, failing to meet the needs of flexible, small-batch customized production. This invention, through a retractable pressure head ring design, allows for the automatic retraction or unfolding of a set of two pressure head rings on the pressure roller. When retracted, the grooves are not pressed, thus directly and quickly adjusting the spacing width of the drainage grooves on the final product. Different drainage groove specifications can be quickly switched on the same production line according to customer order requirements, greatly enhancing the flexibility of the production line and saving the manufacturing, storage, and replacement costs of a large number of spare pressure rollers, as well as the time cost of downtime for mold changes. It reduces inventory, achieves multi-functionality, and automates the adjustment process, significantly improving equipment utilization and overall production efficiency. Attached Figure Description

Both sides of the head ring 16 are provided with annular grooves 26. The inner sides of both ends of the fixing frame 15 are fixedly connected with cylinders 19. One end of each cylinder 19 extends into the annular groove 26. The annular grooves 26 on both sides of the two head rings 16 that hug the outside of the pressure roller 54 are connected to each other. The inner side of the head ring 16 is fixedly connected with a pin 17. The outer side of the pressure roller 54 is provided with a hole 18. One end of each pin 17 is inserted into the hole 18.

[0023] In this design, rectangular blocks 20 are slidably connected inside each cylinder 19, and rectangular columns 23 are fixedly connected to one side of each rectangular block 20.

One end of the connecting shaft 14 is connected to one end of the rotary joint 55. A pipe 30 is installed between the two rotary joints 55. The pipe 30 is connected to the conveying pipe 59 and the interior of the liquid bladder 21 through the rotary joint 55 and the connecting shaft 14, forming a liquid flow line. Liquid is input or output into the liquid bladder 21 through the liquid flow line, controlling the expansion or contraction of the liquid bladder 21, thereby controlling the movement of the rectangular block 20 and the rectangular column 23, and fixing or releasing the pressure head ring 16.

[0024] The base plate 1 is fixedly connected to the top of the electric telescopic rod 8 on one side, and a drive box 9 is fixedly connected to the top of the mounting bracket 10 below it. The top end of the mounting bracket 10 is fixedly connected to one side of the ceiling column 11. The bottom of the pressure block 6 is fixedly connected to the second rack 44. The bottom end of the second rack 44 is inserted into the drive box 9. The drive box 9 is rotatably connected to the drive shaft 42. A second drive gear 43 is fixedly sleeved on the outer side of one end of the drive shaft 42. The second drive gear 43 cooperates with the second rack 44. The other side of the drive box 9 is rotatably connected to the transmission shaft 49. Transmission gears 50 are fixedly sleeved on the outer side of the transmission shaft 49 and the outer side of the drive shaft 42. The diameter of the transmission gear 50 on the drive shaft 42 is smaller than the diameter of the transmission gear 50 on the outer side of the drive shaft 49, thereby driving the pressure head ring 16 to rotate at a certain angle and controlling the opening and closing of the pressure head ring 16.

[0025] In this system, a transmission column 47 is rotatably connected to one side of the inner cavity of the mounting bracket 10. A first sprocket 48, connected to the transmission shaft 49 via a chain drive, is fixedly sleeved on the outer side of both the transmission column 47 and the transmission shaft 49. A transmission rod 45 is rotatably connected to one end of the inner cavity of the mounting bracket 10. A bevel gear 46, meshing with the transmission rod 45 and the transmission column 47, is fixedly sleeved on one end of both the transmission rod 45 and the transmission column 47. A connecting box 56 is fixedly connected to the other side of the rotating bracket 12. One end of the connecting shaft 14 extends into the connecting box 56 and is fixedly sleeved with a first worm gear 27. A connecting rod 28 is rotatably connected between the two ends of the inner cavity of the connecting box 56. The outer side of the connecting rod 28 and... Worm sections 29 are provided below the first worm gear 27, and the two worm sections 29 are respectively connected to the two first worm gears 27 for transmission. The two worm sections 29 have opposite rotation directions. One end of the connecting rod 28 extends into the mounting bracket 10. The outer side of one end of the connecting rod 28 and the outer side of one end of the transmission rod 45 are both fixedly fitted with second sprockets 52 connected by chain drive. The two first worm gears 27 and the two connecting shafts 14 are driven to rotate in opposite directions by the two worm sections 29 with opposite rotation directions, thereby controlling the two pressure head rings 16 to hug the outer side of the pressure roller 54 and to rotate the two pressure head rings 16 off the outer side of the pressure roller 54.

[0026] The pressure block 6 is fixedly connected to a first rack 33 at its bottom and behind the second rack 44. The bottom end of the first rack 33 is inserted into the drive box 9. A first worm 31 is rotatably connected to one side of the inner cavity of the drive box 9 and is located above the drive shaft 42. A first drive gear 32 that cooperates with the first rack 33 is fixedly sleeved on the outer side of the first worm 31. A fixed box 41 is fixedly connected to the back of the drive box 9. One end of the first worm 31 extends into the interior of the fixed box 41 and is rotatably connected to one side of the inner wall of the fixed box 41. A rotating shaft 34 is rotatably connected to one end of the inner wall of the fixed box 41. A second worm wheel 35 that is connected to the first worm 31 is fixedly sleeved on the outer side of the rotating shaft 34. A cam 36 is fixedly sleeved on the outer side of the rotating shaft 34 and behind the second worm wheel 35. The slide plate 40 can be driven to move downward through the cam 36.

[0027] The bottom of the inner cavity of the fixed box 41 is fixedly connected to a piston cylinder 39. A piston column 37 is slidably connected inside the piston cylinder 39. The top end of the piston column 37 extends above the piston cylinder 39 and is fixedly connected to a slide plate 40. A second spring 38 is sleeved on the outside of the piston column 37. The top end of the second spring 38 is fixedly connected to the bottom of the slide plate 40, and the bottom end of the second spring 38 is fixedly connected to the top of the piston cylinder 39. The inlet and outlet ends of the piston cylinder 39 are fixedly connected to pipes 30. Both ends of the pipes 30 pass through the mounting bracket 10 and extend to one side of the zenith column 11 and are respectively connected to one end of two rotary joints 55. When the circular end of the cam 36 rotates towards the slide plate 40, the second spring 38 can push the slide plate 40 and the piston column 37 to move upward.

[0028] Among them, a first motor 51 is fixedly connected to one side of the side plate 2, and the output end of the first motor 51 is fixedly connected to one end of a linkage shaft 3. A winding machine 57 is installed on the top of the bottom plate 1 and behind the pressure roller 54. The winding machine 57 winds up the plate 58 with drainage grooves.

[0029] In summary, the waterproof and drainage board with drainage grooves and its processing method are used such that one end of the board body 58 is wound around the outside of the winding roller on the winding machine 57. When the winding machine 57 winds the board body 58, the board body 58 moves between the pressure roller 54 and the conveyor belt 5. At the same time, the output end of the second motor 53 drives the pressure roller 54 to rotate, so that the pressure roller 54 drives the pressure head ring 16 to rotate outside the pressure roller 54 through the insertion hole 18 and the insertion post 17. When the pressure head ring 16 rotates, the left and right ends of the pressure head ring 16 are limited by the worm gear sections 29 on both sides of the pressure head ring 16 and the cylinder 19 located inside the worm gear section 29 to prevent the pressure head ring 16 from detaching. While the pressure roller 54 and the pressure head ring 16 are rotating, the output end of the first motor 51 drives a linkage shaft 3 to rotate, which in turn drives the outer conveyor roller 4 to rotate. At this time, the conveyor roller 4 drives another conveyor roller 4 to rotate through the conveyor belt 5, which in turn drives another linkage shaft 3 to rotate. This causes the conveyor belt 5 below the plate 58 to move the plate 58 in the winding direction. During the movement, the groove on the top of the pressure block 6 cooperates with the pressure head ring 16 to press grooves into the surface of the plate 58, forming a drainage groove on the surface of the plate 58. Then, the plate 58 with the drainage groove is wound onto the outside of the winding roller on the winding machine 57. If the width of the drainage groove needs to be adjusted, and the drainage groove width needs to be widened, then the two pressure head rings 16 on the outer side of the pressure roller 54 need to be retracted from the outer side of the pressure roller 54. The specific implementation process is as follows: The telescopic end of the electric telescopic rod 8 drives the pressure block 6 to move downward, causing the pressure block 6 to drive the first rack 33 and the second rack 44 to move into the drive box 9. First, the first rack 33 drives the first drive gear 32 to rotate, which in turn drives the first worm gear 31 to rotate. The first worm gear 31 then drives the second worm wheel 35 to rotate the rotating shaft 34, causing the cam 36 to rotate upward by 180 degrees. This causes the round end of the cam 36 to contact the surface of the slide plate 40. At this time, the second spring 38 pushes the slide plate 40 to move the piston rod 37 upward, causing the liquid bladder to... The liquid inside 21 enters the connecting shaft 14, rotary joint 55 and pipe 30 through plate 58, and is drawn into piston cylinder 39 through pipe 30, causing liquid bladder 21 to contract. At this time, the first spring 25 pushes rectangular block 20 and rectangular column 23 to move towards the inner wall of annular groove 26. At this time, pressure roller 54 rotates slowly until pressure head ring 16 rotates to the point where one end of rectangular groove 24 corresponds to one end of rectangular column 23. At this time, one end of rectangular column 23 is inserted into rectangular groove 24 under the pushing force of the first spring 25, and then pressure roller 54 stops rotating. Then the pressure block 6 continues to move downward, causing the first rack 33 to disengage from the first drive gear 32. At this time, the second rack 44 drives the second drive gear 43 to drive the drive shaft 42 and the transmission gear 50 to drive the transmission shaft 49 to rotate. The transmission shaft 49 drives the transmission column 47 to rotate through the two first sprockets 48. The transmission column 47 drives the transmission rod 45 to rotate through the two bevel gears 46. At this time, the transmission rod 45 drives the connecting rod 28 to rotate through the two second sprockets 52. The connecting rod 28 drives the two worm segments 29 to rotate. The two worm segments 29 drive the two connecting shafts 14 to rotate in opposite directions through the two first worm wheels 27. The connecting shafts 14 drive the fixed frame 15 and the cylinder 19, as well as the rectangular column 23 and the rectangular groove 24, to drive the pressure head ring 16 to rotate upward. At this time, the pressure block 6 and the two pressure head rings 16 move to the non-working state at the same time, thereby widening the width of the drainage channel. If it is necessary to narrow the width of the drainage groove, the two retracted pressure head rings 16 need to be re-engaged on the outside of the pressure roller 54, and the pressure block 6 needs to be raised to the working position. The specific working process is as follows: First, the telescopic end of the electric telescopic rod 8 pushes the pressure block 6 upward. At this time, the pressure block 6 drives the first rack 33 and the second rack 44 upward. Then, the second rack 44 first drives the second drive gear 43 to drive the drive shaft 42 and the transmission gear 50 to drive the transmission shaft 49 to reset and rotate. This causes the transmission shaft 49 to drive the transmission column 47 to reset and rotate through the two first sprockets 48. This causes the transmission column 47 to drive the transmission rod 45 to reset and rotate through the two bevel gears 46. At this time, the transmission rod 45 drives the connecting rod 28 to reset through the two second sprockets 52. The rotation causes the connecting rod 28 to drive the two worm gear segments 29 to reset and rotate. The two worm gear segments 29 then drive the two connecting shafts 14 to rotate in opposite directions via the two first worm wheels 27. This causes the connecting shafts 14 to drive the fixed frame 15, the cylinder 19, the rectangular column 23, and the rectangular groove 24 to drive the pressure head rings 16 to rotate downwards. This causes the two pressure head rings 16 to engage with the outer side of the pressure roller 54, allowing the insert pins 17 on the inner wall of the pressure head rings 16 to insert into the insertion holes 18 on the outer side of the pressure roller 54. Then, the pressure block 6 continues to move upwards, at which point the second rack 44... The tooth groove disengages from the second drive gear 43, and then the first rack 33 drives the first drive gear 32 to reset and rotate, causing the first drive gear 32 to drive the first worm 31 to reset and rotate, causing the first worm 31 to drive the second worm wheel 35 to drive the rotating shaft 34 to reset and rotate, causing the cam 36 to rotate downwards by 180 degrees, so that the convex end of the cam 36 contacts the surface of the slide plate 40. At this time, the slide plate 40 pushes the piston rod 37 to move into the piston cylinder 39, and the slide plate 40 compresses the second spring 38, causing the liquid inside the piston cylinder 39 to... The body enters the two rotary joints 55 through the pipe 30, enters the conveying pipe 59 through the connecting shaft 14, and enters the liquid bladder 21 through the conveying pipe 59. This causes the liquid bladder 21 to expand and push the rectangular block 20 to move against the supporting force of the first spring 25. This causes the rectangular block 20 to move one end of the rectangular column 23 out of the rectangular groove 24. At this time, the limit on the pressure head ring 16 is released. The two pressure head rings 16 then re-clamp around the outside of the pressure roller 54, and the pressure block 6 moves up to the working position, thus narrowing the width of the drainage groove.
