Description

Technical Field

[0001] This invention relates to the technical field of tunnel construction, and specifically to a tunnel waterstop installation device. Background Technology

[0002] In the field of tunnel construction technology, tunnel waterproofing and drainage are key and challenging aspects of construction quality. The installation of tunnel waterstops is a crucial component of the tunnel waterproofing and drainage system. Waterstops are typically made of rubber, utilizing their high elasticity to deform under various loads, thus achieving a strong seal and effectively preventing water leakage and seepage in the structure, while also providing shock absorption. Traditional waterstop installation structures are overly complex, and the fixing effect is often poor, easily leading to misalignment during concrete pouring and failing to achieve the desired waterproofing effect.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN216008536U discloses an installation structure for a waterstop in tunnel construction, comprising a fixing component and a waterstop. The fixing component includes a base and a U-shaped plate. A hollow circular tube is formed along the length of the waterstop in its middle section, and water-blocking ribs are formed on both sides of the hollow circular tube. The inner wall of the U-shaped plate matches the outer wall of the waterstop, and a perforation is provided at the bottom of the U-shaped plate. The base is a circular tube with a sealed bottom surface, cast into the edge of a precast slab, and extends along the outer side perpendicular to the circular tube. The wall has a first mounting hole and a second mounting hole. The diameter of the first mounting hole is larger than that of the second mounting hole. Special bolts are provided on the first and second mounting holes. The inner wall of the second mounting hole is threaded. The upper radius of the special bolt is adapted to the first mounting hole, and the lower radius of the special bolt is threaded to the second mounting hole. The diameter of the through hole is larger than that of the second mounting hole but smaller than that of the first mounting hole. This patent provides better fixing effect for the waterstop, allowing the waterstop to be placed flat on the fixing component and making it difficult to be tilted during the concrete pouring process.

[0004] Waterstops are mainly collected on rollers by winding for easy transfer. When in use, they are cut according to the required dimensions, but the cut waterstops remain bent and cannot be kept flat. If the waterstops are applied directly to the aforementioned patent, even if they are placed inside a U-shaped plate, they still cannot be kept flat. Workers are required to help fix the waterstops in the designated position while keeping them flat, which makes the operation cumbersome, increases the labor intensity of workers, and reduces work efficiency. Summary of the Invention

[0005] The present invention aims to provide a tunnel waterstop installation device to solve the problem of cumbersome operation in the existing waterstop installation method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tunnel waterstop installation device, comprising a fixing block, with fixing parts on both sides of the surface of the fixing block, the fixing parts including a support block and a concave block fixedly connected to the fixing block, a bidirectional screw rotatably connected between the two support blocks, and a guide block between the two support blocks; movable blocks are threadedly connected to both ends of the bidirectional screw, the movable blocks are slidably connected to the guide blocks, and a leveling block is connected to the bottom of the movable blocks; a unidirectional screw rotatably connected to the concave block, a pressure block is threadedly connected to the unidirectional screw, and the pressure block is slidably connected to the side wall of the concave block; bolts are vertically threadedly connected to both sides of the top of the concave block; and a linkage mechanism for driving the unidirectional screw to rotate with the bidirectional screw.

[0007] The principle and advantages of this scheme are:

[0008] 1. This solution places the waterstop in two grooves, ensuring that both sides of the waterstop abut against the inner walls of the grooves, and the bottom of the waterstop is in contact with the designated position. Rotating the bolts to install them in the designated position achieves the installation and positioning of the concave blocks and fixing blocks. Compared to existing technologies, this solution uses a manual operation to rotate the bidirectional screw, separating the two leveling blocks and using their movement to level the waterstop. Furthermore, during the rotation of the bidirectional screw, a linkage mechanism drives the unidirectional screw to rotate, causing the pressure block to move downwards. When the pressure block abuts against the waterstop, the bidirectional screw stops rotating, and the unidirectional screw also stops rotating, thus stopping the pressure block. The pressure block then presses and positions the leveled waterstop. Therefore, this solution can achieve the leveling and positioning of the waterstop simply by controlling the rotation and stopping of the bidirectional screw, simplifying operation, reducing the labor intensity of workers, and improving work efficiency.

[0009] 2. When the bidirectional screw in this design stops rotating, the leveling block also stops moving. This means that the leveling block can also be used to tighten the waterstop, thereby enhancing the tightening effect of the waterstop.

[0010] Furthermore, the bottom of the movable block is provided with a bottom groove, and the leveling block is vertically slidably connected to the bottom groove; the fixed part also includes a guide groove and a slider. The guide groove includes an inclined section and a horizontal section opened on the fixed block. The inclined section and the horizontal section are connected. The slider is slidably connected to the inclined section and the horizontal section. The slider is fixedly connected to the leveling block.

[0011] With the above setup, during the rotation of the bidirectional screw, the two movable blocks move away from each other; during the movement of the movable blocks, the movable blocks drive the leveling blocks to move synchronously. Since the slider slides in the inclined section and the horizontal section, and the slider is fixed to the leveling block, the slider drives the leveling block to move downward first, and then move horizontally; when the slider moves to the horizontal section, the leveling block abuts against the surface of the waterstop; when the slider slides in the horizontal section, the leveling block moves on the surface of the waterstop; since the two movable blocks move away from each other, the two leveling blocks also move away from each other, that is, the waterstop is leveled using the two leveling blocks.

[0012] Furthermore, the concave block has side grooves on both sides of its sidewall, with a side block slidably connected in the side groove and a stop block at the bottom of the side block; the side groove has a vertical groove, with a lifting block slidably connected in the vertical groove, and a first spring between the lifting block and the vertical groove, and the side block is fixedly connected to the lifting block; the leveling block has extension blocks on both sides of its sidewall for pressing the side block, the extension blocks are located above the side blocks, the side blocks are located on the movement trajectory of the extension blocks, and the extension blocks can move in the side groove.

[0013] With the above settings, when the slider slides from the inclined section to the horizontal section, the slider drives the leveling block to move downward relative to the bottom groove, which in turn drives the extension block to move downward. This causes the extension block to press the side block downward along the path of the side groove, and the extension block and the side block are always in contact. The side block drives the lifting block to move downward in the vertical groove, and the first spring is compressed. During the downward movement of the side block, the side block also drives the abutment block to move downward. When the slider is in the horizontal section, the abutment block abuts against the waterstop, which can expand the pressing range of the waterstop and thus enhance the pressing effect.

[0014] Furthermore, the concave block has top grooves on both sides of the top, and bolts pass through the top grooves. Nuts are threaded onto the bolts. The top grooves are connected to the side grooves and vertical grooves. The lifting block has a top block for pressing the nut. The top block can move in the vertical groove and the top groove. The nut is located below the top block and is located on the positioning movement trajectory.

[0015] With the above settings, rotating the bolt will install it to the designated position, thus achieving the installation and positioning of the concave block and the fixed block; and during the bolt movement, the bolt will drive the nut to move to the designated position in the top groove, with the nut located below the top block.

[0016] During the downward movement of the lifting block, the lifting block also drives the top block to move downward, that is, the top block moves towards the nut. When the slider is in the horizontal section, the top block abuts against the nut; when the slider slides in the horizontal section, the top block always abuts against the nut; when the bidirectional screw stops moving, the top block still abuts against the nut, which can tighten the nut, thereby strengthening the positioning effect of the bolt, that is, strengthening the positioning effect of the concave block installation, and also strengthening the positioning effect of the waterstop.

[0017] Furthermore, the top of the pressure block is provided with a wedge surface; the side wall of the leveling block is provided with a wedge block for abutting against the wedge surface, the wedge block is located between two extension blocks, and the wedge surface is located on the movement trajectory of the wedge block.

[0018] With the above settings, when the slider slides in the horizontal section, the slider drives the leveling block to move synchronously, and the leveling block drives the wedge block to move synchronously, so that the wedge block moves towards the wedge surface; the leveling block continues to move, and when the bidirectional screw stops moving, the leveling block and the wedge block also stop moving. At this time, the wedge block abuts against the wedge surface, which can enhance the stability of the pressure block pressing the waterstop.

[0019] Furthermore, the abutment block has auxiliary blocks on its side wall, and there is a gap between the two auxiliary blocks; the wedge block can move within the gap, and the two auxiliary blocks can make frictional contact with each other on both sides along the length of the wedge block.

[0020] With the above settings, during the movement of the wedge block, the wedge block can move within the gap, and the two sides of the wedge block can respectively rub against the two auxiliary blocks along the length direction of the wedge block. When the wedge block stops moving, the two sides of the wedge block are still in contact with the two auxiliary blocks. On the one hand, the gap can guide the movement of the wedge block, and on the other hand, it can prevent the wedge block from shifting or shaking, thereby ensuring that the wedge block and the wedge surface are always in contact, and improving the stability of the pressure block pressing the waterstop.

[0021] Furthermore, the linkage mechanism includes a driving bevel gear fixedly connected to the bidirectional screw and a driven bevel gear fixedly connected to the unidirectional screw, with the driving bevel gear meshing with the driven bevel gear.

[0022] With the above configuration, during the rotation of the bidirectional screw, the bidirectional screw drives the driving bevel gear to move synchronously. The driving bevel gear meshes with the driven bevel gear, driving the driven bevel gear to rotate. The driven bevel gear drives the unidirectional screw to rotate.

[0023] Furthermore, a leveling roller is provided at the bottom of the leveling block.

[0024] With the above settings, the contact area is reduced and the friction is decreased by using a leveling roller instead of a leveling block to contact the waterstop, resulting in a smoother leveling effect.

[0025] Furthermore, a handle is provided on the bidirectional screw.

[0026] With the above settings, the operation is more convenient by rotating the bidirectional screw through the handle. Attached Figure Description

[0034] Example

[0035] The basics are as follows: Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 As shown: A tunnel waterstop installation device includes a fixing block 10. Fixing portions are provided on both sides of the surface of the fixing block 10. Each fixing portion includes a support block 11 and a concave block 12 fixedly connected to the fixing block 10. A bidirectional screw 13 is rotatably connected between the two support blocks 11, and a guide block 14 is fixedly connected between the two support blocks 11. Movable blocks 15 are threaded to both ends of the bidirectional screw 13, and the movable blocks 15 are slidably connected to the guide blocks 14. A leveling block 16 is connected to the bottom of the movable blocks 15. A unidirectional screw 20 is rotatably connected to the concave block 12. A pressure block 21 is threaded onto the rod 20. The pressure block 21 is slidably connected to the side wall of the concave block 12. That is, both inner walls of the concave block 12 have vertically opened sliding grooves 24, and the pressure block 21 is slidably connected to the sliding grooves 24. Bolts 22 are threaded vertically onto both sides of the top of the concave block 12. It also includes a linkage mechanism for driving the unidirectional screw 20 to rotate with the rotation of the bidirectional screw 13. The linkage mechanism includes a driving bevel gear 30 fixedly connected to the bidirectional screw 13 and a driven bevel gear 31 fixedly connected to the unidirectional screw 20. The driving bevel gear 30 and the driven bevel gear 31 mesh.

[0036] The bottom of the movable block 15 has a bottom groove 17, and the leveling block 16 is vertically slidably connected to the bottom groove 17. The fixed part also includes a guide groove and a slider. The guide groove includes an inclined section 40 and a horizontal section 41 opened on the fixed block 10. The inclined section 40 and the horizontal section 41 are connected. The distance between the two inclined sections 40 gradually increases from top to bottom. The inclined section 40 is located above the horizontal section 41. The slider is slidably connected to the inclined section 40 and the horizontal section 41. The slider is fixedly connected to the leveling block 16.

[0037] The concave block 12 has vertically formed side grooves 50 on both sides of its sidewalls. A side block 51 is vertically slidably connected within the side grooves 50, and a stop block 52 is fixedly connected to the bottom of the side block 51. A vertical groove 53 is formed within the side grooves 50, and a lifting block 54 is slidably connected within the vertical grooves 53. A first spring 55 is fixedly connected between the lifting block 54 and the vertical groove 53. The side block 51 is fixedly connected to the lifting block 54. The leveling block 16 has extension blocks 56 fixedly connected to both sides of its sidewalls for pressing the side block 51. The extension blocks 56 are located above the side block 51. On the movement trajectory of the extension block 56, the extension block 56 can move within the side groove 50; when the slider moves to the horizontal section 41, the slider drives the extension block 56 to move synchronously through the leveling block 16, so that the extension block 56 squeezes the side block 51 and drives the lifting block 54 to move downward within the vertical groove 53, the first spring 55 is compressed, and at this time the gap at the top of the side groove 50 of the lifting block 54 is sufficient for the extension block 56 to slide in, so that the upper and lower sides of the extension block 56 respectively rub against the top of the side groove 50 and the bottom of the lifting block 54.

[0038] The concave block 12 has top grooves 57 on both sides of its top. Bolt 22 passes through the top groove 57 and is threaded with nut 23. The top groove 57 is connected to the side groove 50 and the vertical groove 53. The lifting block 54 is fixed with a top block 58 for pressing the nut 23. The top block 58 can move in the vertical groove 53 and the top groove 57. The nut 23 is located below the top block 58 and is located on the positioning movement trajectory.

[0039] The top of the pressure block 21 is provided with a wedge surface 60; a wedge block 61 for abutting against the wedge surface 60 is fixedly connected to the side wall of the leveling block 16. The wedge block 61 is located between the two extension blocks 56, and the wedge surface 60 is located on the movement trajectory of the wedge block 61. An auxiliary block 70 is fixedly connected to the side wall of the abutment block 52, and there is a gap between the two auxiliary blocks 70; the wedge block 61 can move within the gap, and the two sides of the wedge block 61 along its length direction can respectively make frictional contact with the two auxiliary blocks 70.

[0040] A leveling roller 80 is fixedly attached to the bottom of the leveling block 16. A handle 90 is fixedly attached to the bidirectional screw 13.

[0041] The specific implementation process is as follows:

[0042] In use, place the waterstop strip in the two grooves so that the two sides of the waterstop strip abut against the inner walls of the two sides of the grooves, and the bottom of the waterstop strip is in contact with the designated position; rotate the bolt 22 to install the bolt 22 to the designated position, thereby realizing the installation and positioning of the concave block 12 and the fixing block 10; and during the movement of the bolt 22, the bolt 22 drives the nut 23 to move to the designated position in the top groove 57, and the nut 23 is located below the top block 58.

[0043] The handle 90 drives the bidirectional screw 13 to rotate, which in turn drives the active bevel gear 30 to move synchronously. The active bevel gear 30 meshes with the driven bevel gear 31, which in turn drives the driven bevel gear 31 to rotate. The driven bevel gear 31 then drives the unidirectional screw 20 to rotate, causing the pressure block 21 to move downwards, i.e., towards the waterstop. The pressure block 21 continues to move downwards until it comes into contact with the waterstop, at which point the bidirectional screw 13 stops rotating, and the unidirectional screw 20 also stops rotating, i.e., the pressure block 21 stops moving. The pressure block 21 then presses and positions the waterstop.

[0044] During the rotation of the bidirectional screw 13, the two movable blocks 15 move away from each other; during the movement of the movable blocks 15, the movable blocks 15 drive the leveling block 16 and the leveling roller 80 to move synchronously. Since the slider slides within the inclined section 40 and the horizontal section 41, and the slider is fixed to the leveling block 16, the slider drives the leveling block 16 and the leveling roller 80 to move downwards first, and then horizontally; when the slider moves to the horizontal section 41, the leveling roller 80 abuts against the surface of the waterstop; when the slider slides within the horizontal section 41, the leveling roller 80 moves on the surface of the waterstop; due to the two As the movable block 15 moves away, the two leveling rollers 80 also move away, thus using the two leveling rollers 80 to level the waterstop. When the bidirectional screw 13 stops rotating, the movable block 15 also stops moving, keeping the leveling block 16 and the leveling rollers 80 in the same horizontal position, thereby completing the leveling of the waterstop and making it flat. At the same time, the leveling rollers 80 expand the pressing range of the waterstop, thereby strengthening the pressing effect. Therefore, when the bidirectional screw 13 stops rotating, the pressure block 21 can press and position the flat waterstop.

[0045] As the slider slides from the inclined section 40 to the horizontal section 41, the slider causes the leveling block 16 to move downward relative to the bottom groove 17, which in turn causes the extension block 56 to move downward. This causes the extension block 56 to press the side block 51 downward along the path of the side groove 50, and the extension block 56 and the side block 51 are always in contact. The side block 51 causes the lifting block 54 to move downward in the vertical groove 53, and the first spring 55 is compressed. During the downward movement of the side block 51, the side block 51 also causes the abutment block 52 to move downward. When the slider is in the horizontal section 41, the abutment block 52 abuts against the waterstop, which can expand the pressing range of the waterstop and thus enhance the pressing effect.

[0046] While the slider slides within the horizontal section 41, it drives the leveling block 16 to move synchronously. The leveling block 16 then drives the extension block 56 to move towards the side groove 50. As the slider continues to move, when the bidirectional screw 13 stops moving, the leveling block 16 stops moving, and the extension block 56 also stops moving. At this time, the extension block 56 slides into the side groove 50, causing its upper and lower sides to abut against the top of the side groove 50 and the top of the lifting block 54, respectively. The reaction force of the first spring 55 acts on the extension block 56 through the vertical block, thereby limiting the extension block 56 and improving the stability of the extension block 56 pressing against the side block 51 so that the abutment block 52 abuts against the waterstop, thus improving the stability of the waterstop pressing.

[0047] During the downward movement of the lifting block 54, the lifting block 54 drives the top block 58 to move downward as well, that is, the top block 58 moves towards the nut 23. When the slider is in the horizontal section 41, the top block 58 abuts against the nut 23. When the slider slides in the horizontal section 41, the top block 58 always abuts against the nut 23. When the bidirectional screw 13 stops moving, the top block 58 still abuts against the nut 23, which can tighten the nut 23 and thus enhance the positioning effect of the bolt 22, that is, enhance the positioning effect of the concave block 12 installation and also enhance the positioning effect of the waterstop. Furthermore, when the bidirectional screw 13 stops moving, the extension block 56 slides into the side groove 50, so that the upper and lower sides of the extension block 56 abut against the top of the side groove 50 and the top of the lifting block 54, respectively. This can improve the stability of the compression of the lifting block 54, and thus the lifting block 54 improves the stability of the tightening of the nut 23 through the top block 58.

[0048] During the sliding of the slider from the inclined section 40 to the horizontal section 41, the slider causes the leveling block 16 to move downward relative to the bottom groove 17, which in turn causes the extension block 56 to move downward, so that the extension block 56 presses the side block 51 downward along the path of the side groove 50. The side block 51 also causes the auxiliary block 70 to move downward through the abutment block 52, so that there is a gap between the two auxiliary blocks 70. During the sliding of the slider in the horizontal section 41, the slider causes the leveling block 16 to move synchronously, and the leveling block 16 causes the wedge block 61 to move synchronously, so that the wedge block 61 moves in the direction of the wedge surface 60. The leveling block 16 continues to move. When the bidirectional screw 13 stops moving, the leveling block 16 and When wedge 61 stops moving, it abuts against wedge surface 60, thereby enhancing the stability of pressure block 21 in pressing the waterstop. During the movement of wedge 61, it can move within the gap, and both sides of wedge 61 along its length can rub against two auxiliary blocks 70. When wedge 61 stops moving, both sides of wedge 61 are still in contact with the two auxiliary blocks 70. On the one hand, the gap can guide the movement of wedge 61, and on the other hand, it can prevent wedge 61 from shifting or shaking, thus ensuring that wedge 61 and wedge surface 60 are always abutting, improving the stability of pressure block 21 in pressing the waterstop.
