Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water-stopping device for expansion joints in aqueducts. Background Technology

[0002] An aqueduct is an elevated water channel used to transport water across rivers, valleys, depressions, and roads. It is widely used in irrigation, flood control, and sediment removal; large aqueducts are even navigable. In practical use, aqueducts are subject to various loads (such as temperature changes, water flow impact, and earthquakes), causing their structure to expand and contract. Therefore, expansion joints need to be installed between aqueducts.

[0003] A typical aqueduct expansion joint water-stopping device consists of a water-stopping installation groove, a steel strip embedded in the bottom of the groove, and a rubber water-stop. Therefore, when in use, the water-stopping installation groove is the basic structure of the entire water-stopping device, the steel strip embedded in the bottom of the groove is fixed to the bottom of the water-stopping installation groove to play an anchoring role, and the rubber water-stop is installed in the water-stopping installation groove.

[0004] However, some existing devices often require the injection of a fixing agent during installation to achieve a tight bond with the expansion joint. Due to the lack of an effective centering and fixing device, the waterstop is prone to shifting during the injection process. This shift not only reduces the sealing performance between the waterstop and the expansion joint but also exacerbates damage to the waterstop when the expansion joint deforms, thus affecting the long-term stability of the waterstop effect. Therefore, a waterstop device for aqueduct expansion joints is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-stopping device for expansion joints in aqueducts, which aims to improve the problem that some existing devices cannot provide good centering and fixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water-stopping device for expansion joints in aqueducts includes a base, a protective mechanism on the top of the base, a water-stopping mechanism on the inner bottom wall of the base, two water-stopping plates fixedly connected to the top of the water-stopping mechanism, and a limiting mechanism on the outside of the two water-stopping plates.

[0008] The water-stopping mechanism includes multiple grab bars, the bottom of which is fixedly connected to the inner wall of the base. A reserved water-stopping groove is fixedly connected to the outside of the multiple grab bars.

Multiple top plates are fixedly connected to the outside of the two centering plates. An expansion joint assembly is fixedly connected to the inner bottom wall of the reserved water-stopping groove.

[0009] As a further description of the above technical solution:

[0010] The expansion joint assembly includes a rubber rod, the outer side of which is fixedly connected to the inner bottom wall of the reserved water-stop groove. The outer side of the reserved water-stop groove is on the adjacent side of the two centering plates. A water-stop strip is fixedly connected to the bottom of the rubber rod. The outer sides of the two water-stop plates are fixedly connected to the outer sides of the water-stop strip. A foam board is fixedly connected to the top of the rubber rod. A sealant is fixedly connected to the top of the foam board.

[0011] As a further description of the above technical solution:

[0012] The protective mechanism includes multiple tie rods, the outer sides of which are fixedly connected to the top of the base, and a guardrail is fixedly connected to the top of the base.

[0013] As a further description of the above technical solution:

[0014] The limiting mechanism includes multiple fixed columns, which are externally fixedly connected to the inner wall of the reserved water-stop groove, and the multiple fixed columns are externally fixedly connected to a locking bracket.

[0015] As a further description of the above technical solution:

[0016] The tops of the two waterstop plates have locking grooves, and the outside of the locking frame fits into the inside of the locking grooves.

[0017] As a further description of the above technical solution:

At the same time, the drainage groove ensures that the fixing agent is injected evenly, which further enhances the fixing effect and sealing performance of the waterstop, avoids leakage problems caused by poor fixing or poor sealing, and increases its service life.

[0023] 2. In this utility model, the fixing column is firmly connected to the inner wall of the reserved water-stop groove, providing reliable fixation for the limiting mechanism and ensuring its stability.

Detailed Implementation

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 2 to 5An embodiment of this utility model is provided: a water-stopping device for expansion joints of aqueducts, including a base 1, a protective mechanism 3 is provided on the top of the base 1, a water-stopping mechanism 2 is provided on the inner bottom wall of the base 1, and two water-stopping plates 4 are fixedly connected to the top of the water-stopping mechanism 2 to prevent water from leaking from the expansion joint. A limiting mechanism 5 is provided on the outside of the two water-stopping plates 4.

[0034] The water-stopping mechanism 2 includes multiple retaining ribs 21, designed to be firmly fixed to the base 1. The bottom of the multiple retaining ribs 21 is fixedly connected to the inner wall of the base 1. A pre-reserved water-stopping groove 22 is fixedly connected to the outside of the multiple retaining ribs 21, designed to provide ample placement space. Two centering plates 23 are fixedly connected to the inner bottom wall of the pre-reserved water-stopping groove 22, designed to provide good support. Multiple drainage channels 24 are opened on the outside of the two centering plates 23, through which the required injectable fixative is drained to the central area of ​​the inner bottom wall of the pre-reserved water-stopping groove 22. Multiple top plates 25 are fixedly connected to the outside of the two centering plates 23, designed to provide good support. An expansion joint assembly, including a rubber rod 26, is fixedly connected to the inner bottom wall of the pre-reserved water-stopping groove 22. The expansion joint assembly includes a rubber rod 26 with good flexibility and compression resistance. The rubber rod 26 is fixedly connected to the outside of the pre-reserved water-stopping groove 22. The outside of the pre-reserved water-stopping groove 22 is adjacent to the two centering plates 23. On one side, a waterstop 29 is fixedly connected to the bottom of the rubber rod 26, mainly to prevent water from leaking from the expansion joint. The two waterstop plates 4 are fixedly connected to the outer sides of the waterstop 29. A foam board 27 is fixedly connected to the top of the rubber rod 26, which fixes the rubber rod 26 through its elastic properties. A sealant 28 is fixedly connected to the top of the foam board 27, mainly to fill the tiny gaps between the foam board 27 and the expansion joint and to seal it. The outer side of the waterstop 29 is curved, so that the rubber rod 26 can be placed in the inner curved area of ​​the waterstop 29 and fixed by the foam board 27. The outer side of the two centering plates 23 is inclined, and the two centering plates 23 are placed opposite each other. After the top plate 25 supports the bottom sides of the waterstop 29, a fixing agent is injected to prevent the waterstop 29 from shifting during fixing. Then, the fixing agent flows into the bottom of the waterstop 29 through the drainage groove 24 to prevent gaps from being formed during injection.

[0035] Reference Figure 1 and Figure 6The protective mechanism 3 includes multiple tie rods 31, which are designed to provide good support. The outer sides of the multiple tie rods 31 are fixedly connected to the top of the base 1. The top of the base 1 is fixedly connected to a guardrail 32, which is designed to provide good protection for personnel. The limiting mechanism 5 includes multiple fixing posts 53, which are designed to provide good fixing. The outer sides of the multiple fixing posts 53 are fixedly connected to the inner wall of the reserved water-stop groove 22. The outer sides of the multiple fixing posts 53 are fixedly connected to a locking frame 51, which is designed to provide good locking ability. The tops of the two water-stop plates 4 have locking grooves 52. The outer side of the locking frame 51 and the inner side of the locking groove 52 fit together, so that the two sides of the water-stop plate 4 can be limited to prevent it from falling off due to water flow impact.

[0036] Working Principle: First, the water-stopping mechanism 2 is firmly fixed to the inner wall of the base 1 by the retaining rib 21, ensuring the stability of the entire water-stopping mechanism 2. The reserved water-stopping groove 22 provides a good placement space for the expansion joint assembly. The centering plate 23, which is fixedly connected to its inner bottom wall, provides support for the water-stopping strip 29 and guides the water-stopping strip 29 into correct position through the inclined design on its outer side. At the same time, the top plate 25 outside the centering plate 23 supports the bottom sides of the water-stopping strip 29 to prevent the water-stopping strip 29 from shifting during fixing. Rubber rods 26 are placed in the inner curved area of ​​the water-stopping strip 29. The rubber rods 26, with their good flexibility and compression resistance, can adapt to the deformation of the expansion joint and apply pressure to the water-stopping strip 29 to enhance the water-stopping effect. Subsequently, foam board 27 is fixed to the top of the rubber rod 26, and its elastic properties are used to further fix the rubber rod 26 to prevent it from shifting when the expansion joint deforms. Sealant 28 is then fixedly connected to the top of the foam board 27. The main function of sealant 28 is to fill the tiny gaps between the foam board 27 and the expansion joint, ensuring a sealing effect. When fixing the waterstop 29, the required fixing agent is guided to the central area of ​​the bottom wall of the reserved waterstop groove 22 through the drainage groove 24, so that the fixing agent can flow evenly into the bottom of the waterstop 29, preventing gaps from being generated during the injection process, thereby ensuring that the waterstop 29 is firmly fixed and has good sealing performance.

[0037] During use, the protective mechanism 3 provides stable support through multiple tie rods 31, which are firmly fixed to the top two sides of the base 1, ensuring the overall stability of the protective mechanism 3. A guardrail 32 is also fixedly connected to the top of the base 1. The guardrail 32 is designed to provide good protection for personnel, preventing accidental contact or proximity to the expansion joint during operation or maintenance, thus avoiding accidents. Simultaneously, multiple fixing posts 53 provide reliable fixation, firmly connected to the inner wall of the reserved water-stop groove 22. A locking bracket 51 is externally fixed to the fixing post 53, designed to provide good locking ability, ensuring a tight fit with the locking groove 52 of the water-stop plate 4. The top of the water-stop plate 4 has a locking groove 52. The cooperation between the locking bracket 51 and the locking groove 52 limits the movement of both sides of the water-stop plate 4, preventing it from falling off due to water flow impact or other external forces, thereby ensuring the stability and reliability of the water-stopping device.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
