Description

Technical Field

[0001] This invention relates to the field of irrigation canal technology, specifically to an auxiliary reinforcement device for irrigation seepage prevention trenches, and also to an auxiliary reinforcement method for irrigation seepage prevention trenches. Background Technology

[0002] Irrigating farmland typically requires the construction of irrigation ditches, and the requirements for ditch design vary depending on the geological conditions. Southern China possesses a unique agricultural and water environment with several significant characteristics. While the south enjoys abundant rainfall, a dense river network, and relatively plentiful water resources, it also faces complex hydrogeological conditions. The soils are predominantly clay or loam, making them susceptible to soil erosion and ground subsidence under long-term irrigation and rainwater runoff. Furthermore, southern agriculture is primarily based on paddy fields, resulting in large irrigation water consumption and placing extremely high demands on the stability and seepage prevention performance of irrigation canals.

[0003] Patent CN212714824U discloses a U-shaped irrigation canal for farmland. The canal body has an insertion protrusion at one end and an insertion groove at the other. The insertion protrusion and groove can be interlocked. Inserting the insertion protrusion on the canal body 1 into the insertion groove on an adjacent canal body improves the connection stability between the two adjacent canal bodies, helps reduce the risk of seepage, and is filled with a sealant, which is concrete. The concrete seals the joint between the two adjacent canal bodies, significantly reducing the risk of seepage.

[0004] Although the connection between two adjacent channel bodies is improved by the fit of the flange and groove, which helps reduce the risk of water seepage, there is a large fit tolerance between the flange and groove due to manufacturing precision and to reduce the difficulty of connection. When using concrete to seal the joint between the two channel bodies, the concrete may only fill the surface part of the joint and cannot fill the internal gap after the flange and groove fit. This means that the ends of the two adjacent channel bodies are not supported, and the channel bodies may shake. This can easily cause the surface concrete of the joint to crack, resulting in the loss of the anti-seepage function. Summary of the Invention

[0005] To address the aforementioned issues, an auxiliary reinforcement device for irrigation seepage prevention trenches is provided. By incorporating a covering mechanism and a clamping mechanism, it prevents the joint between the two main channel bodies from cracking during use, thus avoiding water leakage to the lower end of the main channel body.

[0006] To address the problems of existing technologies, this invention provides an auxiliary reinforcement device for irrigation seepage prevention trenches, comprising a covering mechanism and a pressing mechanism for covering the joint between two adjacent channel bodies. The covering mechanism includes a crossbeam spanning the two edges of the channel body, an inner covering component for covering the inner joint between the two channel bodies, and two outer covering components for covering the outer joint between the two channel bodies. The two outer covering components are respectively disposed at both ends of the inner covering component, and both the inner covering component and the two outer covering components are connected to the crossbeam. The pressing mechanism includes two fixing structures and two pressing structures. The two fixing structures are respectively disposed at both ends of the crossbeam and are used to connect the crossbeam to the two channel bodies. The two pressing structures are respectively disposed at both ends of the crossbeam and apply downward pressure towards the channel body to both ends of the crossbeam.

[0007] Preferably, the inner cover assembly includes an inner cover plate and two first sealing strips; the inner cover plate has an inner cover cavity covering the inner splice seam on one side surface that contacts the splice seam, and an injection port communicating with the inner cover cavity is opened on the other side surface of the inner cover plate; the two first sealing strips are respectively disposed on both sides of the inner cover cavity.

[0008] Preferably, the outer cover assembly includes an outer cover plate and two second sealing strips; the outer cover plate is fitted to the outer surface of the channel body, and the surface has an outer cover cavity that covers the outer splice seam; the two second sealing strips are respectively disposed on both sides of the outer cover cavity.

[0009] Preferably, the upper end of the inner cover plate has an exhaust port that communicates with the inner cover cavity.

[0010] Preferably, the covering mechanism further includes a first driving structure, which is disposed on the crossbeam and is used to drive the two outer covering components to cover the outer splice seam.

[0011] Preferably, the covering mechanism further includes two support structures, which are respectively disposed at both ends of the crossbeam. Each support structure includes a support arm and a tie rod. One end of the support arm is hinged to the end of the crossbeam, and the other end of the support arm abuts against the crossbeam. The two ends of the tie rod are respectively connected to the middle of the support arm and the outer cover plate.

[0012] Preferably, the support structure further includes an auxiliary component disposed at the end of the support arm that abuts against the outer cover plate, the auxiliary component being used to keep one end of the support arm abutting against the outer cover plate.

[0013] Preferably, the fixing structure includes a connecting arm and two clamping assemblies; the middle part of the connecting arm is movably connected to the crossbeam; the two clamping assemblies are respectively disposed at both ends of the connecting arm, and the clamping assemblies are used to clamp the channel body from the inner and outer sides of the channel body.

[0014] Preferably, the pressing structure includes a connecting plate, a second driving structure, and a guide structure; the connecting plate is connected to the crossbeam; the second driving structure is disposed at the upper end of the connecting plate and is used to apply a force toward the channel body to the connecting plate; the guide structure is used to guide and restrict the movement of the connecting plate.

[0015] A method for auxiliary reinforcement of irrigation seepage prevention trenches, applied to an auxiliary reinforcement device for irrigation seepage prevention trenches, includes the following steps:

[0016] S1. First, separate the two outer covering components from the inner covering components, making the distance between the outer covering components and the inner covering components greater than the channel body;

[0017] S2. Then, place both ends of the crossbeam on the two side edges of the channel body, adjust the position of the crossbeam so that the inner covering component covers the inner splice seam.

[0018] S3. Two fixed structures fix the crossbeam in the horizontal position of the channel body. Then, adjust the two pressing structures respectively. The pressing force is transmitted to the inner cover assembly through the crossbeam, so that the inner cover assembly is pressed against the inner wall of the channel body.

[0019] S4. Both outer cover components move toward the inner cover component, and the two outer cover components cover the outer seam.

[0020] S5. Fill the covered seam with fluid sealant.

[0021] The advantages of this invention compared to the prior art are:

[0022] 1. This invention includes a covering mechanism and a pressing mechanism. The two outer covering components in the covering mechanism are separated from the inner covering component, ensuring the distance between them is greater than the width of the channel body. This allows for the subsequent accommodation of the channel body's sidewalls. After the crossbeam's position is adjusted, two fixing structures connect the crossbeam to the two channel bodies, fixing the crossbeam in place and effectively preventing it from shifting during subsequent operations. This avoids deviations in the coverage area of ​​the inner covering component, ensuring the accuracy of the caulking operation. Then, the two pressing structures are adjusted so that the pressing force generated by the two pressing structures is transmitted to the inner covering component through the crossbeam. The inner covering component is then pressed... Under the action of force, it presses tightly against the inner wall of the channel body to form a seal, effectively preventing the filling material from overflowing from the gap between the inner covering component and the channel body. This ensures that the filling material can be concentrated in the splicing area. Then, both outer covering components move towards the inner covering component, so that both the inner and outer sides of the splicing are effectively covered by the covering mechanism, forming a relatively closed space. The fluid filling material can flow evenly towards all parts of the splicing under pressure until the splicing is completely filled by the fluid filling material. This ensures that every gap in the splicing is effectively filled, thereby preventing the splicing between the two channel bodies from cracking during use and avoiding water leakage to the lower end of the channel body.

[0023] 2. This invention features an inner cover plate and two first sealing strips. The two first sealing strips are positioned on both sides of the inner cover cavity to fill the depressions in the inner wall of the channel body, fitting snugly against the channel body to form a good sealing structure. Multiple injection ports on the inner cover plate operate simultaneously, allowing the filler material to quickly enter the inner cover cavity. At the same time, the flow resistance inside the cavity is low, and the filler material can quickly fill the cavity and fully cover the joint. Subsequently, under pressure, the filler material enters the joint vertically, shortening the filling path, thereby enabling the joint to be completely filled in a short time and shortening the construction cycle.

[0024] 3. This invention includes an outer cover plate and two second sealing strips. The second sealing strips fill the gap between the outer cover plate and the channel body to prevent the filler material from overflowing. After the filler material in the outer cover cavity of the outer cover assembly cures, it forms a cover surface that adheres to the outer wall of the channel body. Together with the cover surface formed by the inner cover cavity on the inner side of the channel body, it completely covers the splicing seam area, thereby achieving comprehensive protection for the inner and outer sides of the splicing seam of the channel body and effectively avoiding water leakage caused by shrinkage seams due to the curing and shrinkage of the filler material.

Detailed Implementation

[0036] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0037] Reference Figure 1 As shown in Figure 10: An auxiliary reinforcement device for irrigation seepage prevention trenches includes a covering mechanism 2 for covering the joint between two adjacent channel bodies 1 and a pressing mechanism 3; the covering mechanism 2 includes a crossbeam 21 spanning the two edges of the channel body 1, an inner covering component 22 for covering the inner joint between the two channel bodies 1, and two outer covering components 23 for covering the outer joint between the two channel bodies 1. The two outer covering components 23 are respectively disposed at both ends of the inner covering component 22, and both the inner covering component 22 and the two outer covering components 23 are connected to the crossbeam 21; the pressing mechanism 3 includes two fixing structures 31 and two pressing structures 32. The two fixing structures 31 are respectively disposed at both ends of the crossbeam 21 and are used to connect the crossbeam 21 to the two channel bodies 1. The two pressing structures 32 are respectively disposed at both ends of the crossbeam 21 and apply downward pressure towards the channel body 1 to both ends of the crossbeam 21.

[0038] When splicing the main body 1 of the channel, multiple main bodies 1 are connected in sequence. Then, the bottom of the pre-spliced ​​main body 1 is fixed with cement mortar to prevent the main body 1 from shaking and sinking during long-term use. At this time, the bottom of the main body 1 has been covered. After the cement mortar has cured, it can prevent the filling material from flowing out from the bottom of the splice joint. The outer covering component 23 covers the part of the outer splice joint that is not covered.

[0039] Before using the auxiliary reinforcement device, first separate the two outer covering components 23 from the inner covering component 22 in the covering mechanism 2, making the distance between the outer covering component 23 and the inner covering component 22 greater than the width of the channel body 1 so that the sidewalls of the channel body 1 can be accommodated later. Then, place the two ends of the crossbeam 21 on the two side edges of the channel body 1 respectively, and adjust the position of the crossbeam 21. Use measuring tools to ensure that the crossbeam 21 is directly above the splice joint of two adjacent channel bodies 1. At this time, the inner covering component 22 connected to the crossbeam 21 can completely cover the splice joint on the inner side of the channel body 1, providing an inner barrier boundary for subsequent joint filling work. Next, the crossbeam 21 is connected to the two channel bodies 1 by two fixing structures 31, fixing the crossbeam 21 in position on the channel body 1. This effectively prevents the crossbeam 21 from shifting during subsequent operations, thus avoiding deviations in the coverage area of ​​the inner covering component 22 and ensuring the accuracy of the caulking operation. Then, the two pressing structures 32 are adjusted so that the pressing force generated by the two pressing structures 32 is transmitted to the inner covering component 22 through the crossbeam 21. Under this pressure, the inner covering component 22 presses against the inner wall of the channel body 1, forming a seal and effectively preventing the caulking material from overflowing from the gap between the inner covering component 22 and the channel body 1. To ensure the sealant is concentrated in the joint area, both outer cover components 23 move towards the inner cover component 22. When the two outer cover components 23 completely cover the joint on the outside of the channel body 1, both the inner and outer sides of the joint are effectively covered by the cover mechanism 2. After completing the above steps, fluid sealant is filled into the covered joint. Under pressure, the fluid sealant flows towards the joint and fills it. Because the joint is covered by the inner cover component 22 and the outer cover component 23, a relatively closed space is formed, allowing the fluid sealant to flow evenly towards the joint under pressure. The fluid flows throughout the joint until it is completely filled, ensuring that every gap in the joint is effectively filled. After the fluid filler has cured, its strength increases, fixing the two channel bodies 1 together. At this point, the auxiliary reinforcement device is removed. During long-term use, the two channel bodies 1 can effectively resist external forces such as soil pressure and water flow impact, making it difficult for them to move out of place. This greatly improves the stability of the joint between the two channel bodies 1, thus preventing cracking of the joint between the two channel bodies 1 during use and avoiding water leakage to the lower end of the channel body 1.

[0040] Reference Figure 3 and Figure 4As shown: the inner cover assembly 22 includes an inner cover plate 221 and two first sealing strips 222; the inner cover plate 221 has an inner cover cavity 2211 covering the inner splice seam on one side surface that contacts the splice seam, and the other side surface of the inner cover plate 221 has an injection port 2212 communicating with the inner cover cavity 2211; the two first sealing strips 222 are respectively disposed on both sides of the inner cover cavity 2211.

[0041] Because the gaps in irrigation canal joints are typically narrow, directly injecting fluid sealant into the joint would result in significant resistance as the sealant flows along the joint due to the confined space, slowing the filling process and severely impacting construction efficiency. Therefore, an inner cover cavity 2211 is created on one side of the inner cover plate 221 covering the joint, and multiple injection ports 2212 are provided. When injecting fluid sealant, it is simultaneously injected into the multiple injection ports 2212 on the inner cover plate 221. The flow resistance of the fluid sealant within the inner cover cavity 2211 is less than its flow resistance within the joint; therefore, the injected fluid sealant will have better flow characteristics. First, the inner covering cavity 2211 is filled to achieve full coverage of the splice joint. The two first sealing strips 222 fill the depressions in the inner wall of the channel body 1, which can effectively prevent the fluid sealant from overflowing from the gap between the inner covering plate 221 and the inner wall of the channel body 1. At this time, under the continuous pressure, the fluid sealant can enter the splice joint in a direction perpendicular to the splice joint. Compared with the direct filling method, this filling path through the inner covering cavity 2211 is greatly shortened, which greatly improves the flow speed and filling efficiency of the fluid sealant, so that the splice joint can be completely filled in a short time and the construction cycle is shortened.

[0042] Reference Figure 3 and Figure 5 As shown: the outer cover assembly 23 includes an outer cover plate 231 and two second sealing strips 232; the outer cover plate 231 is attached to the outer surface of the channel body 1, and an outer cover cavity 2311 covering the outer splice seam is opened on the surface; the two second sealing strips 232 are respectively arranged on both sides of the outer cover cavity 2311.

[0043] Because the end surface of the main channel 1 has a high degree of flatness, and common fluid sealant materials have shrinkage characteristics during the curing process, this characteristic often leads to the formation of shrinkage joints between the sealant material and the end of the main channel 1. If not effectively treated, during the long-term operation of the irrigation channel 1, water can easily seep into the sealant material along these shrinkage joints, reducing the seepage prevention performance of the main channel 1. On the inner side of the main channel 1, the inner cover cavity 2211 opened on the inner cover plate 221 forms an arc-shaped cover surface that fits the joint and its surrounding area after the sealant material has cured, effectively preventing water from seeping into the sealant material from the inside of the main channel 1. On the outside, when the fluid sealant enters the outer cover cavity 2311 through the splicing seam, the fluid sealant fills the entire outer cover cavity 2311. As the sealant solidifies, a cover surface tightly bonded to the outer surface of the channel body 1 is formed inside the outer cover cavity 2311. This cover surface and the inner cover component 22 work together to cover the splicing seam area of ​​the channel body 1 in all directions, effectively preventing water from seeping from the outside of the channel body 1 through the shrinkage seam into the sealant. This achieves comprehensive protection for both the inside and outside of the splicing seam of the channel body 1, effectively avoiding water leakage caused by the shrinkage seam due to the solidification and shrinkage of the sealant.

[0044] Reference Figure 3 and Figure 4 As shown: The upper end of the inner cover plate 221 is provided with an exhaust port 2213 that communicates with the inner cover cavity 2211.

[0045] During construction, the inner cover plate 221 adheres to the inner wall of the channel body 1, and the outer cover plate 231 adheres to the outer wall of the channel body 1, thus forming a relatively sealed space with good sealing performance. When fluid caulking material is injected, as the caulking material gradually enters the joint area, the air in this sealed space is compressed, and the air pressure in the space continuously increases, creating reverse resistance to the subsequently injected fluid caulking material. This leads to a continuous increase in the difficulty of injecting the caulking material, seriously affecting construction efficiency. At the same time, if air remains in the sealed space, during the curing process of the caulking material, this air will remain in the cured caulking material in the form of pores. These pores destroy the continuity and density of the caulking material, greatly reducing its density. The reduced leak-proof capability of the sealant after curing is mitigated. Therefore, an exhaust port 2213 is provided at the upper end of the inner cover plate 221. When the fluid sealant is injected, it gradually fills the sealed space from bottom to top. During this process, the air in the sealed space is discharged to the external environment through the exhaust port 2213 along the inner cover cavity 2211. As the air continues to be discharged, the air pressure in the sealed space remains constant, effectively reducing the resistance to the injection of the fluid sealant and ensuring that the sealant can be injected smoothly and efficiently. In this way, the generation of internal pores after the sealant has cured can be minimized, thereby ensuring that the sealant has good continuity and density after curing, and significantly improving its leak-proof performance.

[0046] Reference Figure 3 and Figure 6 As shown: The covering mechanism 2 also includes a first driving structure 24, which is disposed on the crossbeam 21 and is used to drive the two outer covering components 23 to cover the outer splice seam.

[0047] Specifically, the first drive structure 24 includes a first double-ended lead screw 241 and two first moving blocks 242. The two ends of the first double-ended lead screw 241 are connected to the two ends of the crossbeam 21, and the two first moving blocks 242 are respectively connected to the two threaded parts of the first double-ended lead screw 241, and the two first moving blocks 242 are respectively connected to the upper ends of the two outer cover plates 231.

[0048] During construction, the overall position of the covering mechanism 2 needs to be adjusted in the early stage. Since the inner covering component 22 is firmly connected to the crossbeam 21, when the position of the inner covering component 22 is adjusted, the two outer covering components 23 associated with it will move synchronously, ensuring the coordination of the entire covering mechanism 2 in the initial positioning stage. This lays the foundation for the precise cooperation between the outer covering component 23 and the inner covering component 22 in the later stage. When the inner covering component 22 is adjusted to be directly above the splice seam through the crossbeam 21 and its position is fixed, the first drive structure 24 is activated and the first double-headed screw 241 is rotated. As the first double-headed screw 241 rotates at a uniform speed, the two first moving blocks 242 will move towards each other at the same time. Since the first moving blocks 242 are rigidly connected to the outer covering plate 231, the two outer covering plates 231 can move towards the outer wall of the channel body 1 under the drive of the first moving blocks 242 until the outer covering plates 231 are tightly pressed against the outer wall of the channel body 1, thereby completing the coverage of the outer splice seam and ensuring the tightness and stability of the outer covering plate 231 and the channel body 1.

[0049] Reference Figure 6 and Figure 7 As shown: The covering mechanism 2 also includes two support structures 25, which are respectively disposed at both ends of the crossbeam 21. Each support structure 25 includes a support arm 251 and a tie rod 252. One end of the support arm 251 is hinged to the end of the crossbeam 21, and the other end of the support arm 251 abuts against the crossbeam 21. The two ends of the tie rod 252 are respectively connected to the middle of the support arm 251 and the outer cover plate 231.

[0050] Because the outer cover plate 231 needs to fully cover the outer splice seam of the channel body 1, it is usually quite long. During construction, the first double-ended screw rod 241 can continuously apply a force towards the channel body 1 to the upper end of the outer cover plate 231. However, the lower end of the outer cover plate 231 lacks direct support towards the channel body 1, and the sealant will exert a large compressive force on the outer cover plate 231, causing a gap to easily appear between the lower end of the outer cover plate 231 and the channel body 1, resulting in the overflow of fluid sealant. Therefore, a support structure 25 is set up. When the outer cover plate 231 begins to move towards the channel body 1 under the drive of the first double-ended screw rod 241, the outer cover plate 231 is connected to the tie rod. 252 applies a pulling force to the support arm 251. Since one end of the support arm 251 is hinged to the crossbeam 21, under the action of the pulling force of the tie rod 252, the support arm 251 begins to rotate around its hinge point with the crossbeam 21. As the rotation continues, the other end of the support arm 251 gradually approaches and finally comes into close contact with the side of the lower end of the outer cover plate 231. At this time, the support arm 251 forms an effective supporting force for the lower end of the outer cover plate 231. During the subsequent injection of fluid sealant, the lower end of the outer cover plate 231, supported by the support arm 251, always maintains a close fit with the channel body 1, thereby effectively avoiding the gap caused by the compression of the sealant and preventing the overflow of the fluid sealant.

[0051] Reference Figure 6 and Figure 7 As shown: The support structure 25 also includes an auxiliary component 253 disposed at one end of the support arm 251 that abuts against the outer cover plate 231. The auxiliary component 253 is used to keep one end of the support arm 251 abutting against the outer cover plate 231.

[0052] Specifically, the auxiliary component 253 includes a support plate 2531 and at least two roller sets 2532. The middle part of one side of the support plate 2531 is hinged to the support arm 251, and the two roller sets 2532 are arranged at both ends on the other side of the support plate 2531. The roller sets 2532 are connected to the support plate 2531 by an elastic connector 2533.

[0053] As the outer cover plate 231 gradually moves towards the channel body 1 under the drive of the first double-ended screw 241, the support arm 251 also rotates synchronously towards the outer cover plate 231 under the pulling force of the tie rod 252. If one end of the support arm 251 contacts the outer cover plate 231 prematurely, the lower end of the outer cover plate 231 will be subjected to a force towards the channel body 1. As the outer cover plate 231 continues to approach the channel body 1, the force exerted by the support arm 251 on the lower end of the outer cover plate 231 will continuously increase. Under this gradually increasing force, the outer cover plate 231 is prone to deformation, affecting the fit between the outer cover plate 231 and the channel body 1. In this auxiliary component 253, when the support arm 251 rotates toward the outer cover plate 231, the two roller groups 2532 in the auxiliary component 253 will first contact the outer cover plate 231. As the support arm 251 continues to rotate, the roller groups 2532 roll on the surface of the outer cover plate 231. During this process, the elastic connector 2533 plays a buffering role. When the support arm 251 exerts a supporting force on the outer cover plate 231, the elastic connector 2533 will undergo elastic deformation to absorb part of the supporting force, so that the force transmitted to the outer cover plate 231 is effectively buffered and controlled, thereby preventing the outer cover plate 231 from deforming due to excessive force.

[0054] Reference Figure 3 , Figure 8 and Figure 9 As shown: The fixed structure 31 includes a connecting arm 311 and two clamping assemblies 312; the middle part of the connecting arm 311 is movably connected to the crossbeam 21; the two clamping assemblies 312 are respectively disposed at both ends of the connecting arm 311, and the clamping assemblies 312 are used to clamp the channel body 1 from the inner and outer sides of the channel body 1.

[0055] Specifically, the clamping assembly 312 includes a mounting frame 3121, a second double-ended lead screw 3122, two second moving blocks 3123, and two clamping plates 3124. The middle part of the mounting frame 3121 is connected to the end of the connecting arm 311. The two ends of the second double-ended lead screw 3122 are connected to the two ends of the mounting frame 3121. The two second moving blocks 3123 are threadedly connected to the two threaded parts of the second double-ended lead screw 3122, respectively. The two clamping plates 3124 are respectively disposed on the inner and outer sides of the channel body 1, and the two clamping plates 3124 are respectively connected to the two second moving blocks 3123. A rubber gasket 3125 is provided on the side of the clamping plate 3124 that contacts the channel body 1.

[0056] After the crossbeam 21 is adjusted to the accurate position directly above the splice seam, the two clamping components 312 are respectively connected to the two corresponding channel bodies 1. At this time, the two clamping plates 3124 in each clamping component 312 are located on the inner and outer sides of the side wall of the channel body 1. Then, the second double-ended screw 3122 is rotated. As the second double-ended screw 3122 rotates, the two second moving blocks 3123, driven by the second double-ended screw 3122, drive the two clamping plates 3124 to move closer to each other. When the two clamping plates 3124 are tightly pressed against the side wall of the channel body 1, the rotation of the second double-ended screw 3122 is stopped. At this time, due to the rubber gasket 3125... The pressure exerted by the clamping plate 3124 on the channel body 1 can be evenly distributed to the surface of the channel body 1 through the rubber gasket 3125, avoiding damage to the channel body 1 due to excessive local stress. At the same time, the large coefficient of friction between the rubber gasket 3125 and the channel body 1 ensures that the position of the crossbeam 21 on the channel body 1 is firmly fixed. During the subsequent adjustment of the two outer covering components 23, the crossbeam 21 can remain in the initially adjusted position without displacement, thus ensuring the relative positional accuracy of the entire covering mechanism 2 and the splice seam, laying a solid foundation for subsequent caulking operations and ensuring the anti-leakage effect.

[0057] Reference Figure 3 , Figure 8 and Figure 10 As shown: The pressing structure 32 includes a connecting plate 321, a second driving structure 322, and a guide structure 323; the connecting plate 321 is connected to the crossbeam 21; the second driving structure 322 is disposed at the upper end of the connecting plate 321, and the second driving structure 322 is used to apply a force toward the channel body 1 to the connecting plate 321; the guide structure 323 is used to guide and restrict the movement of the connecting plate 321.

[0058] Specifically, the second drive structure 322 includes a drive screw 3221, a first mating plate 3222, and a second mating plate 3223. The drive screw 3221 is vertically arranged and threadedly connected to the connecting arm 311. The first mating plate 3222 is connected to the connecting plate 321 via a bearing. The second mating plate 3223 is drive-connected to the first mating plate 3222 and is connected to the drive screw 3221. The guide structure 323 includes a guide post 3231 and a spring 3232 sleeved on the guide post 3231. One end of the guide post 3231 passes through the connecting arm 311 and the connecting plate 321 and is fixedly connected. The two ends of the spring 3232 abut against the connecting arm 311 and the connecting plate 321, respectively.

[0059] When the crossbeam 21 is positioned directly above the splice seam by the fixing structure 31, and the inner cover plate 221 covers the inner splice seam, the two first sealing strips 222 on the inner cover plate 221 are not yet tightly against the inner wall of the channel body 1. At this time, it is necessary to apply a downward force to the inner cover plate 221 with the help of the pressing structure 32. First, the drive screw 3221 is rotated. As the drive screw 3221 rotates at a constant speed, due to its threaded connection with the connecting arm 311, the drive screw 3221 begins to move downward along the axis and drives the second docking plate 3223 connected to it to rotate synchronously. When the second docking plate 3223 gradually approaches the first docking plate 3222, the state of the first docking plate 3222 is adjusted so that the second docking plate 3223 and the first docking plate 3222 achieve transmission docking. After docking is completed, the rotational movement of the drive screw 3221 is transmitted through the first sealing strip 222. The second connecting plate 3223 is transferred to the first connecting plate 3222. Since the first connecting plate 3222 is connected to the connecting plate 321 through a bearing, and the drive screw 3221 continues to move towards the connecting plate 321, the drive screw 3221 applies a vertical downward force to the connecting plate 321. Under the constraint of the guide structure 323, the connecting plate 321 can only move smoothly downward along the direction of the guide post 3231, and drive the crossbeam 21 connected to it to move synchronously. The downward movement of the crossbeam 21 causes the inner cover plate 221 to move evenly towards the interior of the channel body 1 until the two first sealing strips 222 on the inner cover plate 221 are tightly pressed against the inner wall of the channel body 1, forming a good sealing state. This achieves the tightness between the inner cover plate 221 and the channel body 1, effectively preventing the filling material from overflowing from the gap between the inner cover plate 221 and the channel body 1.

[0060] A method for auxiliary reinforcement of irrigation seepage prevention trenches, applied to an auxiliary reinforcement device for irrigation seepage prevention trenches, includes the following steps:

[0061] S1. First, separate the two outer covering components 23 from the inner covering component 22, so that the distance between the outer covering component 23 and the inner covering component 22 is greater than the channel body 1;

[0062] S2. Then, place both ends of the crossbeam 21 on the two side edges of the channel body 1 respectively, and adjust the position of the crossbeam 21 so that the inner covering component 22 covers the inner splice seam.

[0063] S3. The two fixed structures 31 fix the crossbeam 21 in the horizontal direction of the channel body 1. Then, the two pressing structures 32 are adjusted respectively. The pressing force is transmitted to the inner covering component 22 through the crossbeam 21, so that the inner covering component 22 is pressed against the inner wall of the channel body 1.

[0064] S4. Both outer cover components 23 move toward the inner cover component 22, and the two outer cover components 23 cover the outer seam.

[0065] S5. Fill the covered seam with fluid sealant.
