[0002] In tunnel construction quality, tunnel waterproofing and drainage are key and challenging aspects, and the installation of tunnel waterstops is a crucial link in the tunnel waterproofing and drainage system. Currently, the conventional practice for installing tunnel waterstops is to weld opposing reinforcing bars to both sides of the waterstop for fixation. However, in on-site construction, positioning the steel plate waterstop requires multiple welding of reinforcing bars to prevent significant deviations. Welding reinforcing bars directly to the steel plate waterstop can easily damage the galvanized layer and even result in weld-through. Furthermore, while the lateral distance is controlled by welding the reinforcing bars to the waterstop and the formwork, significant deviations still occur due to human factors during actual construction. The lateral distance between the waterstop and the side formwork is difficult to control during construction, greatly affecting the quality of tunnel waterproofing and drainage. Utility Model Content

[0038] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0039] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0040] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the mechanism must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are set as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," "parallel," or "coaxial" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0041] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0042] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0043] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0044] Example 1

[0045] like Figures 1-3 As shown, this embodiment discloses a positioning clamp for a waterstop, comprising:

[0046] The base 1 is detachably connected to the side mold 10, and the base 1 is provided with an adjustment plate 4 that can move laterally.

[0047] The first clamping mechanism 2 is arranged vertically and clamps the adjusting plate 4 at the end away from the base 1;

[0048] A second clamping mechanism 3 is arranged horizontally and is connected to the top of the first clamping mechanism 2. The second clamping mechanism 3 is used to clamp the waterstop 20.

[0049] This embodiment provides a positioning fixture for a waterstop, comprising a base 1, a first clamping mechanism 2, a second clamping mechanism 3, and an adjusting plate 4. The base 1 is detachably connected to the side mold 10, facilitating quick installation and removal of the positioning fixture on the side mold 10, enabling reuse and reducing construction costs. Furthermore, the adjusting plate 4 can move laterally on the base 1. The first clamping mechanism 2 is clamped on the adjusting plate 4, and the second clamping mechanism 3 is connected to the top of the first clamping mechanism 2. After the second clamping mechanism 3 clamps the waterstop 20, the lateral distance between the waterstop 20 and the side mold 10 is adjusted by the lateral movement of the adjusting plate, thereby achieving the positioning of the waterstop 20 and ensuring the installation quality of the waterstop.

[0050] The positioning clamp for the waterstop in this embodiment is simple to operate and easy to install and dismantle. It not only improves construction efficiency but is also reusable, effectively saving construction costs. Furthermore, the lateral spacing between the waterstop 20 and the side formwork 10 is adjusted by the lateral movement between the adjusting plate 4 and the base 1, which effectively solves the problem of large positioning deviation caused by the traditional method of positioning the waterstop with steel bars. It also avoids welding operations and prevents damage to the waterstop during the process of positioning the waterstop with steel bars.

[0051] In this embodiment, the length direction of the waterstop 20 is taken as the longitudinal direction, and the direction perpendicular to the length of the waterstop 20 is taken as the transverse direction.

[0052] In one or more implementations, such as Figure 2 As shown, the base 1 includes a base plate 11 and a horizontal plate 12 that are perpendicularly connected to each other. The base plate 11 is bolted to the side mold 10, and the horizontal plate 12 has a first transverse strip hole 13 at one end away from the base plate 11.

[0053] The adjustment plate 4 has a second horizontal strip hole 41 at one end near the base 1, and the first horizontal strip hole 13 and the second horizontal strip hole 41 are connected by bolts.

[0054] The first transverse strip hole 13 on the horizontal plate 12 is engaged with the second transverse strip hole 41 of the adjusting plate 4 to achieve transverse movement of the adjusting plate 4 on the horizontal plate 12. After moving to meet the requirements, the adjusting plate 4 is bolted to the horizontal plate 12 by passing a bolt through the first transverse strip hole 13 and the second transverse strip hole 41, thereby achieving relative fixation between the adjusting plate 4 and the base 1.

[0055] Furthermore, such as Figure 2 As shown, at least two second transverse strip holes 41 are provided at intervals on the adjusting plate 4, and at least two first transverse strip holes 13 are provided at intervals on the horizontal plate 12.

[0056] Furthermore, the interval between adjacent second transverse strip holes 41 is equal to the interval between adjacent first transverse strip holes 13, so that multiple second transverse strip holes 41 can correspond to multiple first transverse strip holes 13;

[0057] Furthermore, the number of the first transverse strip holes 13 and the second transverse strip holes 41 are equal.

[0058] In this implementation, such as Figure 4 As shown, the base plate 11 and the horizontal plate 12 form an L-shape, wherein both the base plate 11 and the horizontal plate 12 are made of steel plate.

[0059] In this embodiment, the horizontal plate 12 is made of steel plate.

[0060] In one or more implementations, such as Figure 3 As shown, the first clamping mechanism 2 includes a first U-shaped plate 21 and a first screw 22, with the first U-shaped plate 21 arranged longitudinally;

[0061] The first U-shaped plate 21 includes a first top plate 211 and two first side plates 212 connected to both ends of the first top plate 211. Each first side plate 212 is equipped with a first screw 22, and the two first screws 22 are used to clamp the adjusting plate 4.

[0062] When the first clamping mechanism 2 needs to be clamped on the adjusting plate 4, the adjusting plate 4 is clamped by rotating the first screws 22 on both sides to form a symmetrical force structure, avoiding loosening or displacement caused by single-point force.

[0063] In optional implementations, such as Figure 3 As shown, the first side plate 212 is provided with a first threaded hole 213, and the first screw 22 is threadedly connected to the first threaded hole 213.

[0064] The first screw 22 is engaged with the first threaded hole 213, which facilitates the screw 22 to be screwed in or out of the first threaded hole 213, allowing the screw 22 to move on the first side plate 212. This facilitates the precise control of the clamping degree by rotating the first screw 22, so that the two first screws 22 can clamp the adjusting plate 4.

[0065] Furthermore, such as Figure 3 As shown, a first pressure plate 23 is provided at the end of the first screw 22 near the adjusting plate 4. The first pressure plate 23 increases the contact area between the first screw 22 and the adjusting plate 4, making the clamping force of the first screw 22 act over a larger area, resulting in a more stable clamping, while also preventing the first screw 22 from damaging the adjusting plate 4 during clamping.

[0066] Furthermore, such as Figure 3 As shown, a first gripping plate 24 is provided at the end of the first screw 22 away from the adjusting plate 4. The first gripping plate 24 facilitates manual operation, so that the first screw 22 can be rotated by rotating the first gripping plate 24, thereby improving the convenience of operation.

[0067] In one or more implementations, such as Figure 3 As shown, the second clamping mechanism 3 includes a second U-shaped plate 31 and a second screw 32. The second U-shaped plate 31 is arranged horizontally and is located above the first clamping mechanism 2.

[0068] The second U-shaped plate 31 includes a second top plate 311 and two second side plates 312 connected to both ends of the second top plate 311. A second screw 32 is installed on each second side plate 312. The two second screws 32 are used to clamp the waterstop 20.

[0069] The second side plate 312, which is close to the first clamping mechanism 2, is connected to the first top plate 211.

[0070] When it is necessary to fix the waterstop 20, the waterstop 20 is clamped by rotating the second screws 32 on both sides to form a symmetrical force structure, so as to avoid loosening or displacement caused by single-point force on the waterstop 20.

[0071] Furthermore, the second side plate 312 near the first clamping mechanism 2 is connected to the top surface of the first top plate 211, thereby fixing the second clamping mechanism 3 to the first clamping mechanism 2 together, and the second clamping mechanism 3 is located above the first clamping mechanism 2. After the lateral adjustment plate 4 is moved laterally, the second clamping mechanism 3 and the first clamping mechanism 2 move together to adjust the lateral distance of the waterstop 20.

[0072] The bottom of the second side plate 312, which is close to the first clamping mechanism 2, is connected to the top surface of the first top plate 211.

[0073] In optional implementations, such as Figure 3 As shown, the second side plate 312 is provided with a second threaded hole 313, and the second screw 32 is threadedly connected to the second threaded hole 313.

[0074] The second screw 32 is engaged with the second threaded hole 313, which facilitates the screw 32 to be screwed in or out of the second threaded hole 313, allowing the screw 32 to move on the second side plate 312. This facilitates the rotation of the screw 32 and controls the clamping degree, so that the two screws 32 can clamp the waterstop 20.

[0075] In optional implementations, such as Figure 3 As shown, a second pressure plate 33 is provided at the end of the second screw 32 near the waterstop 20. The second pressure plate 33 increases the contact area between the second screw 32 and the waterstop 20, making the clamping force of the second screw 32 act over a larger area, resulting in a more stable clamping, while also preventing the second screw 32 from damaging the waterstop 20 during clamping.

[0076] Furthermore, such as Figure 3 As shown, a second gripping plate 34 is provided at the end of the second screw 32 away from the waterstop 20. The second gripping plate 34 facilitates manual operation, so that the second screw 32 can be rotated by rotating the second gripping plate 24, thereby improving the convenience of operation.

[0077] Example 2

[0078] like Figure 4 As shown, based on Embodiment 1, the positioning system for a waterstop in this embodiment includes a waterstop 20 and the positioning clamps of Embodiment 1, with multiple sets of positioning clamps spaced apart along the length of the waterstop 20.

[0079] By setting multiple sets of positioning clamps at intervals along the length of the waterstop 20, the waterstop 20 can be positioned at multiple points to prevent it from shifting, ensuring its accurate installation position, thereby guaranteeing the water-stopping function of the waterstop 20 and improving the waterproofing quality of the project.

[0080] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
