Description

Technical Field

[0001] This utility model belongs to the field of channel maintenance technology, and in particular relates to a structural joint repair device suitable for water conveyance channels. Background Technology

[0002] During the operation of the irrigation canal, the polysulfide sealant on the canal slope lining panels gradually aged and detached, posing a safety hazard. On-site inspection revealed that the damage to the polysulfide sealant primarily occurred in the operating water level area or shallow water areas. This is because the polysulfide sealant has poor UV resistance; shallow water areas are exposed to strong sunlight and are subject to water level fluctuations, leading to easy aging and detachment of the sealant. Furthermore, the detached sealant was found at both the transverse and longitudinal structural joints of the canal. Currently, routine maintenance primarily addresses the above-water portion of the lining panels, neglecting to address the underwater detached sealant. The prolonged neglect of maintenance regarding detached polysulfide sealant poses the following engineering risks: firstly, prolonged immersion of structural joints in water exacerbates the risk of water seepage into the canal; secondly, the structural joints cannot accommodate lining panel deformation; and thirdly, the detached sealant negatively impacts the overall appearance of the project.

Detailed Implementation

[0016] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. In the following detailed description of the invention, certain specific details are described in detail. However, those skilled in the art will fully understand the invention for any parts not described in detail.

[0017] Furthermore, those skilled in the art should understand that the accompanying drawings are provided only to illustrate the purpose, features, and advantages of the present invention, and are not actually drawn to scale.

[0018] Furthermore, unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to."

[0019] like Figure 1 , Figure 2 and Figure 3As shown in the figure, this utility model provides a structural joint repair device suitable for water conveyance channels, including a joint cleaning device and a joint filling device. The joint cleaning device is used to clean the structural joint 00 where the sealant has fallen off, and the joint filling device is used to fill the cleaned structural joint 00 with SR plastic waterstop material. The joint filling device includes a handle 2 and a support frame 3 at its lower end. The support frame 3 is equipped with a joint-filling wheel 4, a pressing wheel 5, and a material storage wheel 6. The SR plastic waterstop material is a long strip of SR plastic waterstop 1, which is wound around the disc of the material storage wheel 6. The joint-filling wheel 4 is located on the front side of the support frame 3 and is used to embed the SR plastic waterstop 1 into the structural joint 00 and advance along the structural joint 00. The pressing wheel 5 is used to compact the SR plastic waterstop 1 within the structural joint 00. The material storage wheel 6 is located on the top of the support frame 3. Among them, the width of SR plastic waterstop strip 1 matches the width of the structural joint, and its thickness should be 0.5cm greater than the joint depth.

[0020] In application, the sealant that has come loose from the structural joint is first cleaned and the joint is then scrubbed using a joint cleaning device. Then, an SR plastic waterstop strip is used to fill the joint using a joint filling device. The SR plastic waterstop strip is simultaneously filled and compacted using a pressing wheel 5 and a storage wheel 6. This invention allows for the repair of structural joints with loose sealant without interrupting water flow in the channel. The operation is convenient, quick, and efficient. Simultaneously, the SR plastic waterstop strip is used to fill the structural joint. SR plastic waterstop material possesses unique high plasticity, self-adhesion, cold resistance, heat resistance, aging resistance, and impermeability, enabling underwater construction. It is suitable for sealing joints in underwater or humid environments such as hydropower stations, dams, tunnels, and culverts, and is particularly widely used in concrete structure seepage prevention projects.

[0021] As a preferred structure, such as Figure 1 As shown, the support frame 3 includes two triangular support plates. The seam-sealing wheel 4, the seam-pressing wheel 5, and the material-storing wheel 6 are disposed between the two support plates and correspondingly positioned at the triangular portions of the support plates. The axles of the seam-sealing wheel 4, the seam-pressing wheel 5, and the material-storing wheel 6 are rotatably connected to the corners of the two support plates. This structure simplifies the overall structure, making it more compact and reducing manufacturing costs.

[0022] To further optimize the above solution, a guide hook 7 is also provided on the front side of the support plate. One end of the guide hook 7 is fixedly connected to the front corner of the support plate, and the other end of the guide hook 7 is provided with an upward-opening arc-shaped guide portion. The radius of the guide portion is greater than the depth of the structural joint 00, and it is used to guide the movement along the structural joint 00. The guide hook can guide the sealing wheel running in the structural joint, preventing the sealing wheel from deviating from the structural joint during its movement.

[0023] In another specific embodiment of this utility model, such as Figure 2 , 3 As shown, the gap cleaning device includes a scraper 8 and a brush 9. The scraper 8 is used to clean off-putting sealant, and the brush 9 is used to scrub the structural gaps 00. The scraper 8 is located at the end of the handle 10, and the brush 9 is rotatably connected to the handle 10 via a connecting rod 11. Hanging rings 12 are provided on both sides of the connecting rod 11, and hooks 13 and support rods 14, respectively, are provided at the upper and lower parts of the handle 10 to cooperate with the two hanging rings 12. This structure integrates both cleaning off-putting sealant and scrubbing structural gaps, reducing the number of tools required, making it more convenient to operate and carry, and further improving work efficiency.

[0024] In specific manufacturing, one end of the hook 13 is connected to the middle of the handle 10, and the hook head at the other end can be hooked onto the rear hanging ring 12 of the connecting rod 11. At the same time, one end of the support rod 14 is connected to the lower part of the handle 10, and the other end is provided with a ring. The ring can coincide with the inner hole of the front hanging ring 12 of the connecting rod 11, and the ring and the hanging ring can be connected by a connecting bolt.

[0025] In the specific design, the end of the brush 9 is a T-shaped structure with a protruding center, and the height of the protrusion is not less than the depth of the structural seam (the depth into the structural seam can be controlled at 2.5cm). The T-shaped brush head can simultaneously clean the interior of the structural seam and its outer perimeter. The brush can be an electrically driven circular roller brush (such as...). Figure 2-4 (as shown), or a bar brush driven by a push handle, such as Figure 5 As shown. A stiff-bristled brush can be used for making the brush.

[0026] During the repair, workers do not need to go into the water; they can repair the structural joints by standing on the slope near the water. The specific repair process is as follows: First, use the gap cleaning device to clean the structural gaps; remove the loose sealant, fold the connecting rod with the brush upwards and hang it on the handle with the hook, and use the scraper at the bottom to clean the loose sealant inside the structural gaps.

[0027] After the sealant is removed, lower the connecting rod and fix it with the support rod. By pushing and pulling the handle back and forth, the brush can be used to repeatedly scrub along the direction of the structural joint to remove debris, algae, loose concrete particles, etc. in the structural joint until the joint and surrounding area are clean.

[0028] Then proceed with the caulking operation: First, wrap the SR plastic waterstop strip around the storage wheel. Near the water surface, insert one end of the SR plastic waterstop strip into the structural joint. Push the caulking wheel and the pressing wheel along the direction of the structural joint to initially embed the SR plastic waterstop strip into the gap. Then push the storage wheel and the pressing wheel forward and repeat the pressing action with the pressing wheel until the SR plastic waterstop strip fills the gap densely, fully, and tightly adheres to the sidewall of the gap.

[0029] After the SR plastic waterstop strip is compacted, use a scraper to trim the edges and clean the surface, remove the excess material and retrieve it ashore. The top of the structural joint is flush with the top of the lining plates on both sides.

[0030] This invention enables workers to complete repair work on the lining plate without interrupting water supply, minimizing underwater operations and providing necessary safety protection for workers. After repair, the SR plastic waterproofing material should be densely and fully filled, tightly adhering to the bottom and side walls of the structural joint. The bonding condition should be checked by sampling sections of 20m each; the bonding ratio should be ≥80%, and any unqualified areas must be reworked.

[0031] Compared to the original construction process that required completely dry conditions, this invention allows for work even with water, making construction more convenient, saving costs, and ensuring personnel safety. Calculations show that the original process took 3-5 days to treat a structural joint, while this invention only takes about 15 minutes, significantly shortening the construction cycle.

[0032] In summary, this utility model has the advantages of simple and compact structure and convenient and quick operation. First, the loose sealant in the structural joint is cleaned and scrubbed using a scraper and brush. Then, an SR plastic waterstop strip is filled into the structural joint and compacted using a caulking wheel and a pressing wheel, achieving rapid repair of the structural joint. This utility model can repair structural joints with loose sealant without interrupting water flow in the channel, offering convenient, quick, and efficient operation. Furthermore, this utility model eliminates the need for divers, allowing workers to operate without entering the water, making construction simpler and more convenient.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
