Description

Technical Field

[0001] This utility model relates to the field of expansion joint repair technology, and in particular to a repair device for expansion joints in hydraulic structures. Background Technology

[0002] Expansion joints in hydraulic engineering are gaps specifically designed to accommodate the expansion and contraction of materials. They allow for sufficient space for expansion and contraction when the structure is subjected to external forces such as temperature changes, foundation settlement, and water pressure, thus preventing excessive stress within the structure that could lead to cracks or even failure. Expansion joints effectively separate different parts of the structure, ensuring the overall safety and stability of the hydraulic engineering project.

[0003] Most hydraulic structures require expansion joints. In addition to adapting to various deformations, expansion joints must also achieve good seepage prevention. If the seepage prevention method is not appropriate, leakage can easily occur at the expansion joints. When designing hydraulic structures, effective water-stopping measures need to be taken. Common methods include embedding waterstops, surface filling for water-stopping, or a combination of both, implementing multiple layers of water-stopping.

[0004] Based on the aforementioned technologies, the applicant believes that existing expansion joint repair devices are generally fixed with bolts, resulting in rigid connections. However, expansion joints have a certain deformation capacity, and rigid connections are prone to internal water seepage after a long period of time. In response to the above problems, we have introduced an expansion joint repair device for hydraulic structures. Utility Model Content

[0029] The expansion joint repair device for hydraulic structures disclosed in this utility model is mainly used in the scenario of expansion joint repair.

[0030] Reference Figure 1 - Figure 5 A hydraulic structure expansion joint repair device includes a base 1, an expansion joint 2 inside the base 1, a mounting groove 16 on the top of the base 1, and a repair mechanism inside the expansion joint 2. The repair mechanism includes a repair component and a stabilizing component, which work together. The repair component includes LW water-soluble polyurethane 3, which is injected into the expansion joint 2. A sealing rubber plate 4 is located inside the mounting groove 16 and above the LW water-soluble polyurethane 3. A rubber block 5 is fixedly connected to the bottom of the sealing rubber plate 4, and connecting posts 6 are fixedly connected to the bottom of the rubber block 5 at equal intervals. The connecting posts 6 are inserted into the LW water-soluble polyurethane 3. The stabilizing component includes I-beam slots 7, which are symmetrically located inside the mounting groove 16. A top plate 8 is located inside the mounting groove 16 and above the sealing rubber plate 4. T-shaped grooves 9 are located on both sides of the top plate 8, and rubber I-beam strips 10 are inserted into the T-shaped grooves 9 and the I-beam slots 7. The bottom of the top plate 8 is symmetrically fixed with a positioning plate 11, and the bottom of the inner wall of the mounting groove 16 is symmetrically provided with positioning grooves 12. The size of the positioning groove 12 matches the size of the positioning plate 11, and the positioning groove 12 and the positioning plate 11 are used in conjunction with each other.

[0031] In this embodiment: LW water-soluble polyurethane 3 is injected into the expansion joint 2. LW water-soluble polyurethane 3 is a solid elastic material with an elongation rate of up to 300%; moreover, it expands when exposed to water, with a volume expansion rate of up to 250%, achieving the dual functions of elastic water sealing and water-based water sealing, which is quite practical. Then, the sealing rubber plate 4 is placed inside the placement groove 16, so that the connecting column 6 is fully inserted into the interior of the LW water-soluble polyurethane 3. Then, the top plate 8 is placed on top of the sealing rubber plate 4, and the rubber I-beam strip 10 is inserted into the interior of the I-beam slot 7 and the T-shaped groove 9. This system secures the sealing rubber plate 4 and the top plate 8, which in turn press and tighten the LW water-soluble polyurethane 3. Then, the Z-shaped mounting plate 14 is installed on top of the base 1 using bolts 15. The Z-shaped mounting plate 14 limits and presses the top plate 8. Through the designed repair mechanism, multiple water-stopping functions are achieved, preventing water leakage due to gaps in the expansion joint 2, ensuring the safety of the hydraulic structure, significantly improving the water-stopping effect, and offering a simple and practical structure.

[0032] In the above technical solution, considering that existing expansion joint repair devices are generally fixed with bolts, resulting in rigid connections, and since expansion joints have a certain deformation capacity, rigid connections are prone to internal water seepage after a long period of time, the specific operation is as follows to solve this problem:

[0033] Reference Figure 1 - Figure 5 In a preferred embodiment, arc-shaped protrusions 13 for improving stability are fixedly connected at equal intervals on both sides of the inner wall of the expansion joint 2. Z-shaped mounting plates 14 are symmetrically provided on both sides of the top of the base 1, and bolts 15 are provided inside the Z-shaped mounting plates 14, with the bolts 15 threadedly connected to the base 1. The top of the top plate 8 is provided with an anti-wear coating, the main material of which is chlorinated polyvinyl chloride paint.

[0034] In this embodiment, the arc-shaped raised strip 13 improves the stability of LW water-soluble polyurethane 3 after expansion, while also increasing the contact area and improving water resistance. The Z-shaped mounting plate 14 limits and presses the top plate 8. The anti-wear coating reduces the damage to the top plate 8 caused by friction. The chlorinated polyvinyl chloride paint has good water resistance and anti-corrosion properties, making it suitable for some occasions requiring water resistance and anti-corrosion.

[0035] Working principle: In actual use, the worker injects LW water-soluble polyurethane 3 into the expansion joint 2. LW water-soluble polyurethane 3 is a solid elastic body with an elongation rate of up to 300%; it also expands when it comes into contact with water, with an expansion rate of up to 250%, achieving the dual functions of elastic water sealing and water-based water sealing, which is quite practical. Then, the sealing rubber plate 4 is placed inside the mounting groove 16, so that the connecting column 6 is fully inserted into the interior of the LW water-soluble polyurethane 3. Then, the top plate 8 is placed on top of the sealing rubber plate 4, and the rubber I-beam strip 10 is inserted into the interior of the I-beam slot 7 and the T-shaped slot 9 to fix the sealing rubber plate 4 and the top plate 8. The sealing rubber plate 4 and the top plate 8 can press and tighten the LW water-soluble polyurethane 3. Then, the Z-shaped mounting plate 14 is installed on top of the base 1 with bolts 15. The Z-shaped mounting plate 14 plays a role in limiting and pressing the top plate 8.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions.
