Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, and in particular to a connection structure for lining plates of water channels. Background Technology

[0002] Canal lining slabs are widely used protective structures in farmland water conservancy, irrigation area projects, and water conveyance channels. They are mainly used to prevent canal leakage, erosion, and weed growth, improve water conveyance efficiency, and extend the service life of the project. They are usually made of precast concrete slabs, U-shaped channel slabs, or ecological slope protection bricks, and are laid on the canal slope and bottom through splicing.

[0003] In actual construction, to adapt to different canal types and terrain conditions, it is usually necessary to splice and install multiple lining slabs. Traditional connection methods often use mortar bonding or simple overlapping, relying on manual adjustment of the slab positions and fixation. This construction method is cumbersome, inefficient, and requires high levels of worker skill, making it difficult to guarantee splicing accuracy. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a connection structure for water channel lining plates, which solves the problem of low installation efficiency of water channel lining plates.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A water channel lining plate connection structure includes:

[0007] Multiple water channel units, each having a flow channel; each water channel unit has a slot on one side and an insertion block on the other side in the flow direction; in two adjacent water channel units, the slot of one is inserted into the insertion block of the other; the connection gap between two adjacent water channel units is sealed with a first sealant.

[0008] Furthermore, a cover plate is connected to the top of the water channel unit.

[0009] Furthermore, the cover plate is hinged to the top of the water channel unit.

[0010] Furthermore, a first handle is provided on the cover plate.

[0011] Furthermore, the water channel unit includes a first liner section and a second liner section, which together form the diversion channel; the joint between the first liner section and the second liner section is sealed with a second sealant.

[0012] Furthermore, of the first liner segment and the second liner segment, one is provided with a groove, and the other is provided with a matching fitting block; the groove and the fitting block belonging to the same water channel unit cooperate with each other, and the connection between the groove and the fitting block is the connection between the first liner segment and the second liner segment.

[0013] Furthermore, a filter screen is detachably connected to the water channel unit.

[0014] Furthermore, a second handle is provided on the filter screen.

[0015] Furthermore, both the first and second handles are equipped with anti-slip textures.

[0016] Furthermore, the slot is provided with an elastic sealing strip.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Based on multiple canal units, each with a diversion channel and a slot at one end along the water flow direction, and a corresponding insertion block at the other end, adjacent canal units achieve precise insertion and connection through the insertion block of the preceding unit and the slot of the following unit. This structure has clear assembly guidance, is easy to operate, and requires no complex measurements or repeated manual adjustments. Construction personnel can quickly complete alignment and connection, significantly improving installation efficiency. Adjacent units can automatically achieve axial alignment and lateral positioning during assembly, ensuring continuous and straight connection of each unit, forming a smooth and flat water conveyance channel, effectively guiding the water flow smoothly and reducing hydraulic abrupt changes and local scouring. At the same time, it avoids problems such as misalignment, offset, and height difference caused by inaccurate positioning in traditional construction, realizing standardized, modular, and rapid installation of canal units.

[0019] 2. Based on the connection gap formed after the slot and insert are inserted, this gap is completely filled and sealed with a first sealant. The first sealant is evenly injected into the gap using an injection device, allowing it to fully penetrate the mating surfaces, effectively wetting the contact surfaces of the slot and insert, eliminating residual air, and forming a dense, continuous, bubble-free elastic sealing structure after curing. This sealing method achieves seamless sealing of the joint area, completely eliminating the leakage risks caused by poor sealing, uneven filling, or mortar shrinkage and cracking in traditional splicing structures, and constructing a complete, unbroken waterproof barrier.

[0020] 3. Based on the first sealant filling the joint gap and curing it, a sealing layer with adhesive strength and elasticity is formed. The first sealant has excellent ductility and resilience, enabling it to adapt to minor deformations caused by factors such as changes in ambient temperature, diurnal temperature differences, seasonal freeze-thaw cycles, and slight uneven settlement of the foundation during long-term operation of the canal. Under thermal expansion and contraction or load, the canal unit may experience slight opening and closing or misalignment, and the elastic sealing layer can expand and deform synchronously, avoiding sealing failure due to rigid fracture. This dynamic adaptability effectively prevents cracking, delamination, or embrittlement of the sealing layer, ensuring that the waterproof function continues to perform stably over many years of use.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See Figures 1-2A preferred embodiment of the present invention provides a water channel lining plate connection structure, comprising: a plurality of water channel units 1, each water channel unit 1 having a flow channel 11; on one side of each water channel unit 1 in the flow direction, a slot 12 is provided and an insert 13 is provided on the other side; in two adjacent water channel units 1, the slot 12 of one is inserted into the insert 13 of the other; the connection gap between two adjacent water channel units 1 is sealed by a first sealant.

[0028] Before using this canal lining panel connection structure, on-site layout is required based on the canal's design alignment, slope, and terrain conditions. The foundation layer must be leveled and compacted. Then, prefabricated canal units 1 are laid sequentially along the canal line onto the leveled and compacted foundation layer, ensuring uniform contact and stable support between the bottom of the panels and the ground. When installing adjacent canal units 1, the slot 12 at the front end of the subsequent unit is aligned with the insert block 13 at the rear end of the preceding unit, and slowly pushed in until the slot 12 is fully inserted into the insert block 13, achieving axial connection and positioning between the two units. After insertion, a continuous connection gap is formed between adjacent canal units 1. Next, the first sealant is evenly injected along the connection gap using an adhesive injection device, ensuring the sealant fully fills the gap between the slot 12 and the insert block 13. After completing the single-segment splicing and sealing, subsequent canal units 1 are installed sequentially in the same manner, progressing segment by segment, ultimately forming a well-integrated, reliably sealed, and smoothly aligned lined canal structure.

[0029] Based on the fact that multiple water channel units 1 each have a diversion channel 11, and each water channel unit 1 has a slot 12 at one end along the water flow direction and a corresponding insertion block 13 at the other end, adjacent water channel units 1 achieve precise insertion and mating through the insertion block 13 of the previous unit and the slot 12 of the next unit. This structure has clear assembly guidance, is easy to operate, and does not require complex measurements or repeated manual adjustments. Construction personnel can quickly complete alignment and connection, significantly improving installation efficiency. Adjacent water channel units 1 can automatically achieve axial alignment and lateral positioning during assembly, ensuring that each water channel unit 1 is connected continuously and straight, forming a flat and smooth water conveyance channel, effectively guiding the water flow to transition smoothly, and reducing hydraulic abrupt changes and local scouring. At the same time, it avoids problems such as misalignment, offset, and height difference caused by inaccurate positioning in traditional construction, realizing standardized, modular, and rapid installation of water channel units 1. Based on the connection gap formed by the slot 12 and the insertion block 13 after insertion, this gap is completely filled and sealed with a first sealant. The first sealant is evenly injected into the gap using an injection device, allowing it to fully penetrate the mating surfaces and effectively wet the contact surfaces of the slot 12 and the insert 13, eliminating residual air. After curing, it forms a dense, continuous, and bubble-free elastic sealing structure. This sealing method achieves seamless sealing of the joint area, completely eliminating the leakage risks caused by poor sealing, uneven filling, or mortar shrinkage and cracking in traditional splicing structures, and constructing a complete and unbroken waterproof barrier. Because the first sealant fills the mating gap and cures, it forms a sealing layer with adhesive strength and elasticity. The first sealant has excellent ductility and resilience, enabling it to adapt to minor deformations caused by environmental temperature changes, diurnal temperature differences, seasonal freeze-thaw cycles, and slight uneven settlement of the foundation during long-term operation of the canal. Under thermal expansion and contraction or load, the canal unit 1 may experience slight expansion or contraction, and the elastic sealing layer can expand and deform synchronously, avoiding sealing failure due to rigid fracture. This dynamic adaptability effectively prevents the sealing layer from cracking, delamination, or embrittlement, ensuring that the waterproof function continues to perform stably over many years of use.

[0030] Preferably, in this embodiment, a cover plate 2 is connected to the top of the water channel unit 1. The cover plate 2 matches the upper edge structure of the water channel unit 1, covering the top of the diversion channel 11 to form a closed or semi-closed water conveyance channel. The cover plate 2 ensures the closed nature of the water flow within the channel, effectively isolating the internal water flow from external environmental interference. Its direct function is to prevent external debris such as leaves, silt, and garbage from falling into the diversion channel 11, avoiding water blockage, reduced flow cross-section, or localized siltation, significantly reducing the frequency and workload of dredging and routine maintenance. Simultaneously, the cover plate 2 provides physical protection for the structure within the diversion channel 11, resisting the effects of external trampling, vehicle traffic, and natural factors such as sun exposure, rain, and freeze-thaw cycles, slowing down the aging and damage of the main material of the water channel, and effectively extending the overall service life of the water channel unit 1. In areas with high safety requirements, the cover plate 2 can also provide protection, preventing accidental falls by personnel or animals, thus improving safety. In addition, the surface of the cover plate 2 can be smoothed or decorated to coordinate with the surrounding ground or landscape, which not only improves the overall appearance quality and aesthetics of the canal, but also helps to achieve the standardization and landscaping of municipal facilities.

[0031] Preferably, in this embodiment, the cover plate 2 is hinged to the top of the water channel unit 1. The cover plate 2 can be smoothly opened and closed around the hinge axis, avoiding the cumbersome operation of completely disassembling the cover plate 2. The user only needs to lift one end of the cover plate 2 to rotate it around the axis and open it, exposing the entire internal space of the diversion channel 11, providing ample operating channels for inspection, cleaning and maintenance. This significantly improves the convenience of maintenance. Operators can open the cover plate 2 at any time to remove the sediment, debris or blockages deposited in the diversion channel 11, and promptly check for potential problems such as structural damage, aging of the sealing layer or leakage at the connection points, ensuring that the water channel is always in good operating condition and that the water flows smoothly. Especially in rainy seasons or areas prone to dirt accumulation, this openable design greatly shortens maintenance time and improves operation and maintenance efficiency. In addition, the hinged structure has good mechanical stability and durability, and can withstand frequent opening and closing and external loads. At the same time, with the help of the limiting device or support rod, the cover plate 2 can be stably fixed in the open state to ensure operational safety. After closing, the cover plate 2 remains tightly fitted to the top of the canal. If necessary, a sealing strip can be added to further improve the sealing and seepage prevention performance.

[0032] Preferably, in this embodiment, a first handle 21 is provided on the cover plate 2. The first handle 21 is fixed at an appropriate position on the surface of the cover plate 2, typically near the edge and ergonomically designed for easy operation, providing the operator with a clear and comfortable point of force application. When it is necessary to open or close the cover plate 2, the operator can easily achieve the flipping action of the cover plate 2 around the hinge axis by gripping the first handle 21 and applying an upward pulling force, avoiding the difficulty of gripping due to smooth surfaces or limited space. This design significantly improves the convenience and safety of operation, especially in rainy weather, humid environments, or when hands are wet and slippery, the first handle 21 effectively prevents slipping or loss of hand, ensuring stability and safety during operation. At the same time, this design reduces the force required to open and close the cover plate 2, allowing the elderly, women, or maintenance personnel with weaker physical strength to easily complete the operation, improving the user-friendliness of the equipment. The first handle 21 is usually made of corrosion-resistant and high-strength materials, such as stainless steel, engineering plastics or rubber-coated metal parts, with good anti-aging and rust prevention properties, and can be used outdoors for a long time without being easily damaged.

[0033] Preferably, in this embodiment, the water channel unit 1 includes a first liner section 14 and a second liner section 15, which together form the diversion channel 11; the joint between the first liner section 14 and the second liner section 15 is sealed with a second sealant. This structure adopts a split design, which not only facilitates factory prefabrication, transportation, and on-site installation, but also allows for flexible adjustment of the water channel cross-sectional shape and size according to actual engineering needs. The second sealant can be a flexible sealing material with high bonding strength, good elasticity, and water resistance, which can fully penetrate into the micropores of the splicing interface, forming a continuous and dense waterproof layer after curing, effectively blocking the seepage path of water along the gap between the plates. This sealing structure can adapt to temperature changes, foundation micro-deformation, and water pressure fluctuations during long-term operation, maintaining good conformability and integrity, and preventing leakage failure due to cracking or delamination. The first lining section 14 and the second lining section 15 support each other after splicing, forming a synergistic force-bearing system. This improves the bending and compressive strength of the lining structure, making it particularly suitable for environments subjected to high-velocity water flow impact or large external loads. Even under long-term water pressure or dynamic loads, the structure remains stable, preventing local deformation or failure, ensuring that the diversion channel 11 does not leak, bulge, or fail under high-pressure, high-speed water conveyance conditions. Simultaneously, the excellent seepage prevention performance effectively prevents water from seeping into the channel foundation layer, reducing the risk of the foundation soil being softened by immersion, uneven settlement, or scouring, thus ensuring the structural safety and durability of the entire canal system.

[0034] Preferably, in this embodiment, one of the first liner segment 14 and the second liner segment 15 is provided with a groove 16, and the other is provided with a matching interlocking block 17; the groove 16 and the interlocking block 17, belonging to the same water channel unit 1, cooperate with each other, and the connection between the groove 16 and the interlocking block 17 is the connection between the first liner segment 14 and the second liner segment 15. This structural design enables the two liner segments to form a precise mechanical alignment in the transverse direction, effectively guiding the installation process and ensuring that the first liner segment 14 and the second liner segment 15 are accurately positioned and have uniform gaps when they are joined, avoiding misalignment, offset, or poor overlap caused by human operation deviations. It achieves precise positioning and tight fit between the two liner segments, significantly improving the flatness of the splicing surface and the bonding quality. After the interlocking block 17 is inserted into the groove 16, a stable interlocking structure is formed between the two, which can effectively transmit shear force, resist water flow impact and relative slippage caused by external loads, and enhance the overall structural rigidity and mechanical stability of the water channel unit 1. More importantly, this interlocking structure provides ideal interface conditions for subsequent sealing. After the groove 16 and the interlocking block 17 are fitted together, the outer joint can be completely sealed by filling with a second sealant. Because the two are tightly bonded, the sealant layer has a uniform width and reasonable stress distribution, making it less prone to cavities or weak areas, thus further improving the waterproof reliability of the joint. Even during long-term operation, slight stress caused by temperature changes or minor deformation of the foundation can maintain the integrity of the connection, preventing cracking or detachment of the sealing layer due to liner displacement, and eliminating the risk of leakage.

[0035] Preferably, in this embodiment, a filter screen 3 is detachably connected to the water channel unit 1. The filter screen 3 is typically located below the inner side of the cover plate 2 and corresponds to the water passage section of the diversion channel 11. It effectively intercepts leaves, silt, plastic fragments, and other suspended debris as water flows through, preventing these impurities from entering downstream pipes or outlets and causing blockages in the drainage system or damage to pumping station equipment. The filter screen 3 adopts a modular design, allowing for quick connection to the main body of the water channel unit 1 or the cover plate 2 structure via snaps, grooves, or bolts, facilitating installation and disassembly. This design significantly improves the pretreatment capacity of the water channel, enabling active interception of pollutants without interrupting water flow, keeping the inside of the diversion channel 11 clean, and preventing debris accumulation that reduces flow capacity. Simultaneously, because the filter screen 3 is located below the cover plate 2 and is coordinated with the overall structure, it does not affect the cleanliness of the water channel's appearance when normally closed, maintaining the overall aesthetics of the ground or road facilities. Furthermore, this design greatly simplifies daily maintenance. During regular cleaning, operators can simply open the hinged cover 2 to remove the entire filter screen 3 for rinsing or cleaning, without needing to enter the channel, thus reducing maintenance difficulty and safety risks. After cleaning, reinstallation restores the protective function and enables efficient recycling.

[0036] Preferably, in this embodiment, the filter screen 3 is provided with a second handle 31. The second handle 31 provides the operator with a clear and comfortable gripping point, facilitating the application of force during cleaning or replacement, enabling the smooth removal and accurate repositioning of the filter screen 3, significantly simplifying the cleaning and replacement process. When the filter screen 3 has trapped a large amount of debris and needs cleaning, maintenance personnel only need to open the cover plate 2 and easily pull the filter screen 3 vertically from its installation position or along the guide rail by holding the second handle 31, avoiding the inconvenience or slippage risk of manual operation. This design is especially safe and efficient in wet, oily, or confined spaces. Furthermore, the introduction of the second handle 31 greatly improves the efficiency of maintenance operations, shortens operation time, reduces system downtime due to dredging or maintenance, and ensures the continuous water flow capacity of the drainage channel during the rainy season or high-load operation. At the same time, the standardized grip structure also facilitates multi-person collaboration or the use of auxiliary tools for rapid processing, further improving the speed of operation and maintenance response. By setting a second handle 31 on the filter screen 3, not only is a convenient and reliable way to apply force for the installation and removal of the filter screen 3 provided, but the efficiency and safety of daily maintenance are also effectively improved, the labor intensity is reduced, and the channel system is always in good operating condition. This is an important detail design for achieving efficient management and long-term operation of drainage facilities.

[0037] Preferably, in this embodiment, both the first handle 21 and the second handle 31 are provided with anti-slip textures. These textures are distributed on the surface contact area of ​​the handle in the form of regular or irregular friction-enhancing structures, which can significantly increase the friction between the hand and the handle. During the opening and closing of the cover plate 2 or the installation and removal of the filter screen 3, even if the operator's hands are wet, damp, or wearing slippery gloves, a stable grip can still be achieved, effectively preventing slippage or loss of hand when applying force. This design is specifically designed for the application characteristics of water channel systems that are often in outdoor humid, rainy, or high-humidity environments, providing additional safety protection. In rainy weather, during flushing operations, or when the groundwater level is high, traditional smooth handles are easily made difficult to grip due to surface water accumulation, posing operational difficulties and even safety hazards. Handles with anti-slip textures can maintain good grip performance, ensuring a smooth and controllable operation process, and improving the overall safety and reliability of the operation. At the same time, the shape of the anti-slip textures conforms to ergonomic design, which not only enhances functionality but also improves operational comfort and reduces hand fatigue caused by prolonged gripping.

[0038] Preferably, in this embodiment, the slot 12 is provided with an elastic sealing strip. The elastic sealing strip is typically made of rubber or polymer material with excellent resilience and weather resistance, and is pre-embedded or embedded in the inner wall or bottom of the slot 12. When adjacent water channel units 1 are connected to the insert block 13 through the slot 12, the elastic sealing strip undergoes controllable compression deformation under the pressure of the insert block 13 wall during insertion, tightly adhering to the surface of the insert block 13, thereby effectively filling the minute gaps between the slot 12 and the insert block 13, including irregular gaps caused by manufacturing tolerances, transportation deformation, or installation deviations. The effect is to form a continuous, dense, and self-adaptive physical sealing barrier, significantly improving the airtightness of the joint and preventing water from seeping through the gaps between the plates under water pressure. Even when the joint dynamically opens and closes due to temperature changes or minor foundation displacement, the elastic sealing strip can still maintain contact pressure through its resilience, maintaining the sealing effect and preventing leakage channels. This structure further enhances the waterproofing performance of the connection points of the water channel unit 1. It works synergistically with the externally applied first sealant to form a multi-layered waterproofing system: the elastic sealing strip provides initial, active sealing, while the first sealant achieves overall external sealing and structural reinforcement. The two complement each other, significantly improving the reliability of the joint under complex working conditions. Furthermore, this design has excellent construction adaptability, functioning stably under varying environmental temperatures, humidity levels, and on-site installation precision requirements. This reduces the stringent requirements on assembly processes and improves construction efficiency and quality consistency.
