Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction technology, specifically relating to a fixing buckle for waterstops embedded in tunnels. Background Technology

[0002] Waterproofing is a crucial step in tunnel construction. Inadequate waterproofing can lead to water seepage not only during construction but also after the tunnel is operational, creating a risk of flooding and severely impacting the overall quality and safety of the tunnel project.

[0003] Water seepage in tunnels primarily occurs at construction joints. During the gradual pouring of the tunnel sidewalls from bottom to top, horizontal transverse joints extending longitudinally along the tunnel are formed, their length equal to the length of the poured section. To effectively prevent seepage at these longitudinal construction joints, water-stopping components are typically installed. Embedded waterstops, as a widely used water-stopping component, have a decisive impact on waterproofing quality due to their effective fixation.

[0004] However, current waterstop fixing technology lacks unified standards and specifications, leading to significant differences in project quality due to varying fixing methods employed by different construction teams. Some teams use reinforcing bars for mutual support and positioning on both sides, while others go so far as to drill holes in the rubber waterstop and suspend it with wire. These methods fail to accurately position the embedded waterstop, and during concrete pouring, the waterstop's position is easily deformed, displaced, or even damaged by the concrete pressure, thus affecting its water-stopping performance and reducing its effectiveness. Furthermore, using reinforcing bars for positioning is a one-time investment that cannot be recycled, increasing construction costs and wasting steel materials.

[0005] Meanwhile, the complex tunnel construction environment places high demands on the efficiency and convenience of waterstop fixing. With the expansion of tunnel construction scale and the continuous improvement of waterproofing requirements, a more reliable and efficient waterstop fixing method is needed to effectively solve the aforementioned technical problems and ensure the quality and safety of tunnel waterproofing construction. Utility Model Content

[0006] In order to solve the technical problems existing in the prior art, this utility model proposes a fixing buckle for waterstops buried in tunnels.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A fixing buckle for embedding waterstop in a tunnel includes a left positioning clamp and a right positioning clamp symmetrically arranged. The middle parts of the left and right positioning clamps are connected by a clamping bolt. The upper part of the left positioning clamp is provided with a positioning block. At least one set of cooperating waterstop clamping components are provided on the left and right positioning clamps below the clamping bolt. The right positioning clamp is provided with a fixing component.

[0009] In a further technical solution, the positioning block is a channel steel and is hinged to the left positioning clamp.

[0010] In a further technical solution, the waterstop clamping assembly includes two clamping rings, symmetrically arranged on the inner sides of the left positioning plate and the right positioning plate, and the clamping rings are made of rubber resin material.

[0011] In a further technical solution, both the left and right positioning clamps are threaded with movable bolts, and the clamping ring is fixedly installed on the movable bolts.

[0012] In a further technical solution, both the left positioning clamp and the right positioning clamp are made of angle steel.

[0013] In a further technical solution, the fixing component includes an adjusting support and a fixed support, wherein the adjusting support is fixedly mounted on the right positioning clamp, and the fixed support is mounted on the adjusting support.

[0014] In a further technical solution, the adjusting support is provided with a sliding groove, and the fixed support is slidably installed in the sliding groove by two adjusting bolts.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a fixing buckle for waterstop buried in a tunnel, including a left positioning clamp 1 and a right positioning clamp 2 symmetrically arranged. The middle parts of the left positioning clamp 1 and the right positioning clamp 2 are connected by a clamping bolt 3. The upper part of the left positioning clamp 1 is provided with a positioning block 4. The left positioning clamp 1 and the right positioning clamp 2 are provided with at least one set of cooperating waterstop clamping components below the clamping bolt 3. The right positioning clamp 2 is provided with a fixing component.

[0027] The specific usage process of this fixing buckle is as follows:

[0028] First, the installation area needs to be cleaned to ensure it is free of debris and dust, providing a clean environment for the installation work. Next, the quality and specifications of the waterstop and the fixing clips are checked to ensure they meet design requirements, and installation tools such as electric drills and wrenches are prepared. Then, the fixing clips are installed and fixed at the corresponding positions on the lining formwork trolley according to the design spacing, ensuring that the fixing components on the right positioning clamp 2 of the fixing clip are firmly fixed to the trolley formwork. Afterwards, the waterstop is accurately placed between the left positioning clamp 1 and the right positioning clamp 2, and the distance between the left positioning clamp 1 and the right positioning clamp 2 is adjusted using the clamping bolts 3 to tighten the entire fixing clip, thus initially fixing the waterstop. Then, by adjusting the waterstop clamping components, which are arranged vertically within the fixing clip, the waterstop is further fixed through their combined action, effectively preventing loosening during installation or subsequent construction. Next, following the length of the waterstop, perform the aforementioned fixing operations sequentially to ensure the waterstop is installed flat and free from twisting or wrinkling. This completes the waterstop fixing process. Compared to traditional waterstop fixing techniques, this fixing clip effectively secures the waterstop, ensuring its horizontal alignment is straight, its vertical position is centered, and it possesses good stability. After fixing, it is less affected by subsequent construction, preventing deformation, displacement, or even damage during concrete pouring. This ensures the waterstop remains in the correct position, thus guaranteeing its water-stopping performance and improving its effectiveness. Furthermore, this fixing clip is easy to install and remove, and can be reused, effectively reducing construction time and costs, improving construction efficiency, and assisting construction personnel in quickly completing installation work in the complex environment of tunnel construction. More importantly, the use of this fixing clip has standardized and normalized the waterstop fixing process, reduced quality fluctuations caused by differences in the technical skills of construction personnel, ensured the stable and reliable quality of the waterproofing project, thereby reducing safety hazards after the tunnel is put into operation and providing strong protection for the safe operation of the tunnel.

[0029] In one specific embodiment, the positioning block 4 is a channel steel and is hinged to the left positioning clamping plate 1.

[0030] The positioning block 4 ensures the stability of the fixing buckle. The left positioning clamp 1 and right positioning clamp 2, through the cooperation of the clamping bolts 3 and positioning block 4, ensure a tight fit between the waterstop and the waterstop clamping assembly, effectively locking the waterstop and preventing displacement during installation and subsequent construction, thus achieving the desired waterproofing effect. Furthermore, using channel steel to manufacture the positioning block 4 results in a simple structure, convenient processing, and the ability to reprocess scrap or waste steel, contributing to resource recycling and further reducing costs, thus adhering to the principle of economic efficiency.

[0031] In one specific embodiment, the waterstop clamping assembly includes two clamping rings 5, symmetrically arranged on the inner sides of the left positioning clamping plate 1 and the right positioning clamping plate 2, and the clamping rings 5 ​​are made of rubber resin material.

[0032] Two clamping rings 5 ​​are respectively clamped on both sides of the waterstop to ensure its stability during installation and subsequent construction. The use of rubber resin material gives the clamping rings 5 ​​a certain buffering capacity, reducing the risk of damage to the waterstop due to improper construction.

[0033] In one specific embodiment, both the left positioning clamp 1 and the right positioning clamp 2 are threaded with movable bolts 6, and the clamping ring 5 is fixedly installed on the movable bolts 6.

[0034] The clamping rings 5 ​​are mounted on the left positioning plate 1 and the right positioning plate 2 via movable bolts 6. The gap between the two clamping rings 5 ​​can be increased or decreased by rotating the movable bolts 6, thus adapting to waterstops of different specifications and sizes, demonstrating extremely high flexibility and versatility. Regardless of the tunnel engineering environment or the required size of the waterstop, it ensures that the waterstop is stably and effectively clamped. It is worth mentioning that, for easy adjustment of the clamping rings 5, adjustment can be made only on one side using the movable bolts 6.

[0035] In one specific embodiment, both the left positioning clamp 1 and the right positioning clamp 2 are made of angle steel.

[0036] Both the left positioning clamp 1 and the right positioning clamp 2 are made of angle steel, which has good rigidity and ensures that the waterstop can be stably clamped during tunnel waterproofing construction, preventing its displacement or detachment. Moreover, angle steel is a common material with various specifications and sizes, which can meet the needs of different tunnel waterproofing constructions, while reducing production costs. It has important practical value and promotion significance in tunnel waterproofing construction.

[0037] In one specific embodiment, the fixing component includes an adjusting support 7 and a fixed support 8. The adjusting support 7 is fixedly mounted on the right positioning clamp 2, and the fixed support 8 is mounted on the adjusting support 7.

[0038] The fixing component, through the cooperation of the adjusting support 7 and the fixed support 8, allows the adjusting support 7 to extend out from the gap between the reinforcing bars and be connected and fixed to the trolley template through the fixed support 8, thereby effectively fixing the fixing buckle and ensuring the stability of the fixing buckle during use.

[0039] In one specific embodiment, the adjusting support 7 is provided with a sliding groove 9, and the fixed support 8 is slidably installed in the sliding groove 9 by two adjusting bolts 10.

[0040] The fixed support 8 is slidably installed in the groove 9 of the adjusting support 7 by two adjusting bolts 10. This design allows the fixed support 8 to be adjusted within a certain range of displacement in the left and right directions along the groove 9, and can be flexibly adjusted according to the needs of different application scenarios, which greatly enhances the applicability and practicality of this fixing buckle.

[0041] In one specific embodiment, the fixed support 8 is provided with two sets of fixing holes 11 arranged vertically to cooperate with the adjusting bolts 10.

[0042] With two sets of fixing holes 11 set at the top and bottom, this design allows the fixing support 8 to be fixed on the adjusting support 7 at different heights. Combined with the left and right adjustment capability, this further enhances the flexibility of the fixing buckle and improves its applicability and practicality.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
