Description

Technical Field

[0001] This invention relates to the field of construction technology for longitudinal waterstops in tunnel inverts, and particularly to a protective device for the construction of longitudinal waterstops in tunnel inverts. Background Technology

[0002] The invert arch is a reverse-curved reinforced concrete structure that arches upwards from the bottom of the tunnel towards the ground. It serves as the foundation and sealing point for the tunnel lining, forming a closed stress ring together with the arch wall lining. This is crucial for ensuring the stability of the tunnel. When laying the invert arch floor, a waterstop needs to be pre-embedded in the invert arch. The waterstop is a special waterproof sealing component for construction joints, settlement joints, and expansion joints in concrete structures. It blocks the seepage path through elastic deformation or rigid barriers, and can adapt to joint displacement caused by temperature, load, and foundation settlement. It maintains a long-term seal, prevents liquid leakage, and also has a slight shock absorption and buffering effect. According to the installation position, waterstops can be divided into embedded, external, and removable types. Among them, embedded waterstops are mostly used in the construction of invert arches.

[0003] When laying the waterstop for the invert arch, it is generally divided into longitudinal laying and circumferential laying. When laying longitudinally, the waterstop needs to be straightened first using a tensioner, and then the waterstop is fixed to the side of the concrete mold of the invert arch using clamps. The above process not only involves the erection of the tensioner support, but also requires the cooperation of many people, which is time-consuming and labor-intensive. Moreover, when laying the waterstop, a part of the waterstop needs to be reserved outside the concrete for subsequent construction. However, the reserved part of the waterstop is easily damaged by worker misoperation or collision with on-site machinery, resulting in the project not meeting the standards. Summary of the Invention

[0004] Given the problems of complex, time-consuming, and labor-intensive waterstop laying process and easy damage in existing technologies, a construction protection device for longitudinal waterstops in tunnel invert arches is proposed.

[0005] Its purpose is to improve the efficiency of waterstop laying, reduce the difficulty of waterstop laying, and protect the reserved part of the waterstop.

[0006] The technical solution of the present invention is a construction protection device for longitudinal waterstop of tunnel invert arch, including a concrete mold, a fixed rail fixedly installed on the top of the concrete mold, two connecting frames fixedly installed at both ends of the fixed rail, a clamping mechanism installed on one side of the fixed rail, and a straightening mechanism installed on one side of each connecting frame.

The two sides of the inner wall of the protective cover are respectively rotatably arranged on the inner wall of slide rail one and the inner wall of slide rail two through the rotating seat. Slide rail two is divided into an arc-shaped part and a vertical part. The arc-shaped part of slide rail two is used to provide a turning track for the protection. The width of the vertical part of slide rail two is greater than that of slide rail one, which can provide a certain sliding space for clamping plate two.

[0009] Furthermore, the rolling element includes cross grooves respectively opened on the sides of each clamping plate one and clamping plate two, square shells symmetrically arranged on the sides of each cross groove, extrusion rubber slidably arranged on the inner wall of each square shell, extrusion wheel arranged on the inner wall of the square shell, push plate slidably arranged on the inner wall of the square shell where clamping plate two is located, and extrusion screw rotatably arranged on the side of the push plate.

[0010] Furthermore, a pair of square shells are symmetrically arranged on the side of each cross groove. The two ends of the shaft of the extrusion wheel are slidably disposed on the inner wall of the cross groove and the square shell through bearings. The extrusion wheel passes through both sides of the cross groove. The push plate is located only on the inner wall of one of the square shells of the clamping plate. One end of the extrusion screw is rotatably disposed on the side of the push plate, and the other end is threadedly connected to the side of the square shell. The extrusion screw is used to adjust the position of the push plate.

[0011] Furthermore, the fastener includes a transmission plate with elongated holes on its side, control blocks one fixedly disposed at both ends of the transmission plate, short rails fixedly disposed on the side of each control block one, control blocks two slidably disposed on the inner wall of each short rail, elastic plates disposed on the side of the transmission plate, and top rods fixedly disposed at both ends of the elastic plates.

[0012] Furthermore, the transmission plate is fitted onto the side of each transmission rod through an elongated hole, the limiting plate abuts against the side of the transmission plate, the sides of control block one and control block two are provided with smooth surfaces that gradually thicken, the thickness of control block two is greater than that of control block one, each of the top rods abuts against the side of control block two, and the middle part of the elastic plate is fixedly connected to the middle part of the transmission plate.

[0013] Furthermore, each of the fixing components includes a fixing frame and a fixing plate, a pair of tightening screws rotatably disposed on the inner wall of the fixing frame, the fixing plate slidably disposed on the inner wall of the fixing frame, the tightening screws being located at both ends of the inner wall of the fixing frame, each tightening screw penetrating different ends of the fixing plate, one set of fixing components being located on the inner wall of the rotating frame, the fixing frame located on the inner wall of the rotating frame being rotatably disposed on the inner wall of the rotating frame, the output end of the drive motor penetrating through the top of the rotating frame and fixedly disposed on the top of the fixing frame, and protruding posts being fixedly disposed at both ends of the fixing frame located outside the rotating frame.

[0014] Furthermore, the sliding member includes a sliding rail formed on the side of each connecting frame, a C-shaped frame slidably disposed on the inner wall of the sliding rail via a strip plate, a sliding block fixedly disposed on the side of each C-shaped frame, and a sliding frame fixedly disposed on the side of each sliding block.

[0015] Furthermore, each of the sliding blocks is slidably disposed on the inner wall of the elongated hole of the transmission plate, and the end of each sliding block away from the C-shaped frame abuts against the side of a different control block one, and the ends of the sliding frame are slidably disposed on the side of a different control block two.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention significantly improves the convenience of clamping and fixing waterstops by optimizing the design of the clamping mechanism and the rolling element, effectively saving manpower. The rolling element, through the combination of cross groove, extrusion wheel and extrusion screw, makes the clamping operation of waterstops more convenient. The worker only needs to adjust the extrusion screw to change the position of the push plate to easily push the waterstop between the extrusion wheels. Compared with the traditional manual point-by-point fixing method, only one worker is needed to complete the clamping and placement of a long longitudinal waterstop without the need for multiple people to cooperate. This not only simplifies the clamping process and improves the operating efficiency, but also significantly reduces labor costs. At the same time, it lays a convenient foundation for the subsequent straightening and final clamping of the waterstop.

[0017] 2. This invention achieves simultaneous and convenient operation of straightening and clamping of the waterstop through the linkage design of the sliding component and fastener in the straightening mechanism. This ensures that the straightness of the waterstop meets construction requirements. The straightening mechanism clamps both ends of the waterstop through two fasteners, and the drive motor rotates the fasteners, easily pulling the waterstop to a straight state. The position of the fasteners can be flexibly adjusted according to the elasticity and tension requirements of the waterstop material, adapting to different construction scenarios. The linkage between the sliding component and the fastener means that after the waterstop is pulled to the preset degree, the fastener drives the U-shaped frame to slide. Through the cooperation of the sliding block and the control block, the first clamping plate and the second clamping plate automatically move closer together, achieving automatic clamping of the waterstop without additional manual operation. Throughout the process, the straightening and clamping of the waterstop do not require separate operation. The strong linkage avoids the bending and displacement problems that are prone to occur during manual straightening, ensuring the straightness of the fixation. It also simplifies the operation process, reduces the difficulty of operation for workers, ensures the quality of waterstop fixation, and effectively improves the construction efficiency and quality of longitudinal waterstops in tunnel inverts.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1, referring to Figures 1-2 This invention provides a first embodiment of a construction protection device for a longitudinal waterstop in a tunnel invert, comprising a concrete mold 1. The concrete mold 1 is concave, similar in shape to the invert, and has a platform at its edge for installing a waterstop clamping mechanism. A fixed rail 2 is fixedly mounted on the top of the concrete mold 1. The device also includes two connecting frames 3 fixedly mounted at both ends of the fixed rail 2, which are respectively located at both ends of the fixed rail 2 and are used to connect a straightening mechanism 5. A clamping mechanism 4 is located on one side of the fixed rail 2, and a straightening mechanism 5 is located on one side of each connecting frame 3. The clamping mechanism 4 clamps the waterstop, while the straightening mechanism 5 pulls the waterstop from both ends to ensure its straightness.

[0022] Example 2, refer to Figures 2-9This is the second embodiment of the present invention, which differs from the first embodiment in that: the clamping mechanism 4 includes several movable frames 41 slidably disposed on the inner wall of the fixed track 2, a clamping plate 42 fixedly disposed on the end of each movable frame 41 away from the fixed track 2, a clamping plate 43 disposed on the side of each clamping plate 42, a transmission rod 44 fixedly disposed on the side of each clamping plate 43, and a limiting plate 45 detachably disposed on the end face of each transmission rod 44. The limiting plate 45 is a circular plate with a diameter larger than that of the transmission rod 44, and a stud is fixedly disposed on one side of it. A threaded groove is opened on the end of the transmission rod 44 away from the clamping plate 43. The positioning plate 45 is threadedly connected to the inner wall of the threaded groove of the transmission rod 44 by a stud. When disassembly is required, the positioning plate 45 can be removed simply by rotating the stud. The removable positioning plate 45 facilitates the installation of the transmission plate 481. The protective part 46 is set on the side of the clamping plate 42, the rolling part 47 is set on the side of the clamping plate 42 and the clamping plate 43, and the fastener 48 is set on the side of the transmission rod 44. Several moving frames 41 are linearly and uniformly arranged on the inner wall of the fixed track 2. Each clamping plate 42 is directly opposite a different clamping plate 43. The end of the transmission rod 44 away from the clamping plate 43 passes through the clamping plate 42.

[0023] Different numbers of clamping plates 42 and 43 can be installed inside the fixed track 2. While ensuring the clamping effect, the protective cover 463 in the protective component 46 can also provide sufficient protection for the waterstop.

[0024] Protective component 46 includes a slide rail 461 fixedly mounted on the side of each clamping plate 42 near the movable frame 41, a slide rail 462 fixedly mounted on the side of each clamping plate 43 away from the movable frame 41, a protective cover 463 mounted above each clamping plate 42 and clamping plate 43, and a clearance hole 464 formed on the side of the protective cover 463. Each pair of slide rails 461 and 462 is provided in pairs, with each pair of slide rails 461 symmetrically arranged on the side of the clamping plate 42. 2. Symmetrically arranged on the side of clamping plate 2 43, a rotating seat is fixedly installed at the opening of the inner wall of the protective cover 463. The two sides of the inner wall of the protective cover 463 are respectively rotatably set on the inner wall of slide rail 1 461 and slide rail 2 462 through the rotating seat. Slide rail 2 462 is divided into an arc-shaped part and a vertical part. The arc-shaped part of slide rail 2 462 is used to provide a turning track for the protection. The width of the vertical part of slide rail 2 462 is greater than that of slide rail 1 461, which can provide a certain sliding space for clamping plate 2 43.

[0025] The protective component 46 primarily protects the exposed concrete surface of the waterstop using protective covers 463. To ensure the protective covers 463 fully cover the waterstop, the width of each protective cover 463 must be greater than the distance between the outermost edges of clamping plates 42 and 43. For easy storage, a rotating seat is provided at the opening of the inner wall of the protective cover 463. The protective cover 463 is rotatably mounted on the inner walls of slide rails 461 and 462 via the rotating seat. Figure 3 As shown, the rotating seat on one side of the protective cover 463 slides on the inner wall of slide rail 461, while the rotating seat on the other side slides in cooperation with the arc-shaped part of slide rail 462. This allows the protective cover 463 to rotate 90° along the top of slide rail 461, and finally allows the rotating seat on the other side to slide along the arc-shaped track to the vertical part of slide rail 461. Then, the protective cover 463 slides down along slide rail 461 and slide rail 462, and the protective cover 463 can cover the waterstop between clamp 42 and clamp 43, thereby achieving the purpose of protecting the waterstop. The clearance hole 464 provides a certain space for the components on the side of clamp 42 and clamp 43 to pass through the protective cover 463.

[0026] The rolling element 47 includes cross grooves 471 respectively formed on the sides of each clamping plate 42 and clamping plate 43, square shells 472 symmetrically arranged on the sides of each cross groove 471, extrusion rubber 473 slidably disposed on the inner wall of each square shell 472, extrusion rollers 474 disposed on the inner wall of the square shells 472, push plates 475 slidably disposed on the inner wall of the square shells 472 where clamping plate 43 is located, and extrusion screws 476 rotatably disposed on the side of the push plates 475. A pair of square shells 472 are symmetrically arranged on the sides of each cross groove 471. The two ends of the shaft of the extrusion rollers 474 are slidably disposed on the cross grooves 471 via bearings. The inner walls of the groove 471 and the square shell 472 are connected by an extrusion wheel 474 that passes through both sides of the cross groove 471. The push plate 475 is located only on the inner wall of one of the square shells 472 in the clamping plate 43. One end of the extrusion screw 476 is rotatably mounted on the side of the push plate 475, and the other end is threadedly connected to the side of the square shell 472. The extrusion screw 476 is used to adjust the position of the push plate 475. Since the extrusion screw 476 is threadedly connected to the side of the square shell 472, rotating the extrusion screw 476 can adjust the extension height of the extrusion screw 476, thereby changing the pressure applied by the push plate 475 to the extruded rubber 473.

[0027] The rolling element 47 is mainly used to facilitate the clamping of the waterstop between clamping plates 42 and 43. When the waterstop is placed between clamping plates 42 and 43, the sliding element 54 provides an initial clamping force to clamping plates 42 and 43. This force is only enough to ensure that the waterstop is clamped by the extrusion wheel 474 and does not fall off. The worker only needs to fix one end of the waterstop in the fixing element 53, and then pass the other end of the waterstop through different combinations of clamping plates 42 and 43 one by one. Each time it is passed through, the position of the push plate 475 is adjusted by the extrusion screw 476, so that the extrusion wheel 474 rotates and is subjected to extrusion at one end. As the elasticity of rubber 473 decreases, the waterstop can be pushed between the two extrusion rollers 474. The worker then resets the extrusion screw 476 and pulls the end of the waterstop to the next set of clamping plates 42 and 43. The advantage of this process is that only one worker is needed to place the long longitudinal waterstops between the clamping mechanisms 4, which is not only efficient but also saves labor costs. Furthermore, this process does not require clamping each clamp individually, facilitating the automatic clamping of clamping plates 42 and 43 later. The remaining structure is the same as in Embodiment 1.

[0028] Example 3, referring to Figures 6-10 This is the third embodiment of the present invention, which differs from the second embodiment in that: The straightening mechanism 5 includes a rotating frame 51 fixedly disposed at one end of each connecting frame 3 away from the fixed track 2, a drive motor 52 fixedly disposed at the top of the rotating frame 51, a pair of fixing members 53 disposed on the side of the rotating frame 51, and a sliding member 54 disposed on the side of the connecting frame 3.

[0029] Two fasteners 53 are located in different positions. One is located inside the rotating frame 51 and is used to fix the end of the waterstop. The other is used to directly clamp the two ends of the waterstop. Each fastener 53 includes a fixing frame 531 and a fixing plate 532. A pair of tightening screws 533 are rotatably disposed on the inner wall of the fixing frame 531. The fixing plate 532 is slidably disposed on the inner wall of the fixing frame 531. The tightening screws 533 are located at both ends of the inner wall of the fixing frame 531. Each tightening screw 533 passes through different ends of the fixing plate 532. One set of fasteners 53 is located on the inner wall of the rotating frame 51. The fixing frame 531 located on the inner wall of the rotating frame 51 is rotatably disposed on the inner wall of the rotating frame 51. The output end of the drive motor 52 passes through the top of the rotating frame 51 and is fixedly disposed on the top of the fixing frame 531. The two ends of the fixing frame 531 located outside the rotating frame 51 are respectively fixedly disposed with protruding posts 534.

[0030] The fixing member 53 clamps both ends of the waterstop strip between the fixing frame 531 and the fixing plate 532 in a state perpendicular to the axis of the rotating frame 51 by tightening screw 533. The fixing member 53, located on the inner wall of the rotating frame 51, is connected to the drive motor 52 and clamps the ends of the waterstop strip inside. By rotating the fixing member 53 by the drive motor 52, the waterstop strip can be tightened. By clamping and fixing both sides of the waterstop strip at the same time and pulling it with the drive motor 52, the waterstop strip can be pulled straight. Since the clamping conditions at both ends of the waterstop strip are the same, when the waterstop strip is straightened, it will naturally become straight under the pulling force of the drive motor 52. Moreover, due to the pulling force, the waterstop strip becomes thinner as a whole, and the friction force of the extrusion wheel 474 on the waterstop strip decreases. This allows the waterstop strip to become straight directly without being affected by the friction force of the extrusion wheel 474.

[0031] The sliding member 54 includes a sliding rail 541 opened on the side of each connecting frame 3, a C-shaped frame 542 slidably disposed on the inner wall of the sliding rail 541 via a strip plate, a sliding block 543 fixedly disposed on the side of each C-shaped frame 542, and a sliding frame 544 fixedly disposed on the side of each sliding block 543. Each sliding block 543 is slidably disposed on the inner wall of the elongated hole of the transmission plate 481. One end of each sliding block 543 away from the C-shaped frame 542 respectively abuts against the side of a different control block 482. The ends of the sliding frame 544 are slidably disposed on the side of a different control block 483.

[0032] The fastener 48 includes a transmission plate 481 with elongated holes on its side, control blocks 482 fixedly disposed at both ends of the transmission plate 481, short rails fixedly disposed on the side of each control block 482, control blocks 483 slidably disposed on the inner wall of each short rail, an elastic plate 484 disposed on the side of the transmission plate 481, and top rods 485 fixedly disposed at both ends of the elastic plate 484. The transmission plate 481 is sleeved on the side of each transmission rod 44 through the elongated holes. A limiting plate 45 abuts against the side of the transmission plate 481. The sides of control blocks 482 and control blocks 483 have smooth surfaces that gradually thicken. The thickness of control block 483 is greater than that of control block 482. Each top rod 485 abuts against the side of control block 483. The middle part of the elastic plate 484 is fixedly connected to the middle part of the transmission plate 481.

[0033] The sliding member 54 can work with the fastener 48 to automatically clamp the first clamp 42 and the second clamp 43. Before straightening begins, the two ends of the waterstop are respectively equipped with the fixing member 53, and the position can be changed according to the different materials of the waterstop and actual needs. If the elasticity is high, or if the actual tightness of the waterstop needs to be high, the fixing part 53 can be placed further away from the shaped frame 542, and vice versa. After being pulled to a certain extent, the protrusions 534 at both ends of the fixing frame 531 can contact the two ends of the shaped frame 542 respectively. Under the pull of the drive motor 52, the shaped frame 542 is forced to slide. The sliding block 543, along with the sliding frame 544, controls the side sliding of the first control block 482 and the second control block 483 respectively. Under the push of the sliding block 543, the first control block 482 moves away from the first clamping plate 42 along with the transmission rod 44. At this time, the second clamping plate 43 follows the transmission rod 44 and moves closer to the first clamping plate 42, so that the first clamping plate 42 and the second clamping plate 43 can get close, thereby completely clamping the waterstop.

[0034] The sliding frame 544 pushes the control block 483, which is thicker than the control block 482, causing the two ends of the elastic plate 484 to lift up. This causes the middle part of the plate to exert a spring force on the transmission plate 481 away from the clamping plate 42, ensuring that the transmission plate 481 is subjected to uniform force. Each pair of clamping plates 42 and 43 is clamped together by the transmission rod 44.

[0035] Furthermore, since the sliding distance of the U-shaped frame 542 within the sliding rail 541 is limited, the middle portion of the waterstop cannot be pulled further when it is in an extreme position. The fixing member 53 can be manually adjusted according to the waterstop material and actual needs. Therefore, employees can adjust the position of the fixing member 53 based on the actual condition of the waterstop, ensuring that the fixing member 53 compresses the U-shaped frame 542 to its limit position before the waterstop breaks or exceeds actual requirements, thus guaranteeing the safety of the waterstop and achieving the accuracy required for construction. The remaining structure is the same as in Embodiment 2.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
