Description
TECHNICAL FIELD
[0001] The application relates to the technical field of channels, in particular to a construction structure of a farmland channel. BACKGROUND
[0002] As the core of farmland water conservancy infrastructure, farmland channels play a crucial role in agricultural production. They undertake key functions such as irrigation, drainage, and groundwater level regulation, and their construction quality directly affects the efficiency of water resource utilization and the yield of crops. A scientifically reasonable and high-quality channel system can significantly reduce seepage loss during water delivery and improve irrigation guarantee rate, which is of great significance to the sustainable development of modern agriculture. With the advancement of agricultural modernization, the construction and optimization of farmland channels have attracted increasing attention, and their development has played a key role in ensuring agricultural water safety and promoting agricultural yield increase.
[0003] In the early stage, the construction of farmland channels mainly adopted the on-site pouring of concrete process. Although this method can make the channel structure have good integrity, it has many problems. On the one hand, the construction period is long and is easily affected by weather conditions. Once bad weather occurs, the construction has to be suspended. On the other hand, this process requires a large amount of labor, and the construction quality is difficult to control. With the development of building industrialization and prefabricated technology, the prefabricated farmland channel construction mode gradually emerges. This mode divides the channel into standardized prefabricated components, such as U-shaped channels and plate components, which are mass-produced in factories and then transported to the site for assembly. This construction method improves construction efficiency, shortens construction period, reduces environmental pollution caused by on-site wet work, and facilitates quality control due to the precise size of the components.
[0004] However, the existing prefabricated farmland channel construction method has obvious defects. After assembling multiple prefabricated channel components on site, cement is usually used for connection and fixation, but before the cement solidifies, the connection between the components is not stable enough. When backfilling soil, mechanical rolling or slight uneven settlement of the foundation occurs, the channel components are easily extruded by external forces and appear misaligned, warped or differentially settled, which destroys the smoothness of the channel alignment, changes the joint width between the components, and seriously affects the overall sealing and anti-seepage performance of the channel, resulting in water loss. To solve this problem, a complex support and formwork system needs to be additionally built to temporarily fix the components during construction, which increases the construction cost and complexity, offsetting the efficiency advantage brought by prefabricated construction. SUMMARY
[0005] In order to reduce the possibility of misalignment between prefabricated components during construction, the application provides a construction structure of a farmland channel.
[0006] The application provides a construction structure of a farmland channel, which adopts the following technical scheme: A construction structure for a farmland irrigation canal includes multiple canal components evenly arranged along the canal's extension direction. One end of each canal component is a first abutment portion, and the end of each canal component facing away from the first abutment portion is a second abutment portion. The first abutment portions and the second abutment portions of adjacent canal components abut against each other. Multiple connecting posts are evenly spaced and arranged at the first abutment portion; The second abutting part has a connecting groove that corresponds to the first abutting part. The connecting post is inserted into the connecting groove, and there is a gap between the outer peripheral sidewall of the connecting post and the peripheral sidewall of the connecting groove. A limiting post is provided on the wall of the connecting groove, and there are multiple limiting posts that are evenly spaced along the circumference; When the connecting post is inserted into the connecting groove, the end of the limiting post abuts against the outer peripheral sidewall of the connecting post; The mounting post is rotatably connected to the end of the connecting post. The mounting post and the connecting post are coaxially arranged, and the diameter of the mounting post is less than or equal to the diameter of the connecting post. A limiting block slides circumferentially on the outer periphery of the mounting post. There are multiple limiting blocks and they are evenly spaced circumferentially. The mounting post is provided with an elastic power member. The elastic power member drives the limiting block to slide until the end facing away from the elastic power member abuts against the mounting post. A through space is formed between adjacent limiting posts for the limiting block to slide through. The supporting column is slidably connected to the connecting column along the axial direction; A drive column is disposed at one end of the bearing column. The drive column is slidably connected to the mounting column and the connecting column along the axial direction. The drive column and the mounting column are rotatably connected and coaxially arranged. A driving ball is provided on the outer periphery of the driving column, and a driving groove is provided in the mounting column that extends along a spiral trajectory and allows the driving ball to slide. The connecting post is provided with an elastic driving member, which drives the driving post to protrude outside the mounting post, at which time the limiting block is aligned with the through space. When the limiting block slides into the through space, the driving column abuts against the groove wall on the side of the connecting groove away from the groove opening; When the connecting groove wall pushes the drive column into the mounting column, the drive ball drives the mounting column to rotate, and at this time the limiting block slides and squeezes the elastic power member.
[0007] By adopting the above technical solution, multiple channel components are evenly arranged along the channel extension direction and abut against each other through the first and second abutment parts, which facilitates the splicing of the channel; the connecting column is inserted into the connecting groove and has a gap with the groove wall, and the limiting column abuts against the outer peripheral side wall of the connecting column, which can preliminarily position the connecting column; the installation column is rotatably connected to the end of the connecting column, and when the limiting block passes through the through space, it slides to abut against the side of the limiting column away from the opening of the connecting groove, realizing a stable connection between adjacent channel components, reducing the possibility of misalignment between prefabricated components during construction, and eliminating the need for additional support and formwork systems, which greatly improves the construction speed.
[0008] Optionally, the elastic driving component is a driving spring, and the connecting column is provided with a bearing groove for the bearing column to slide. The drive spring is installed in the bearing groove, and the drive spring drives the bearing column to slide in the direction of the mounting column.
[0009] By adopting the above technical solution, a drive spring is used as an elastic drive component and installed in the bearing groove inside the connecting column. This can drive the bearing column to slide in the direction of the mounting column, allowing the drive column to protrude out of the mounting column.
[0010] Optionally, the outer periphery of the mounting column is provided with a sliding groove for the limiting block to slide, the side wall of the limiting block is provided with a limiting block, and the groove wall of the sliding groove is connected to a limiting groove for the limiting block to slide. The elastic dynamic component is a dynamic spring, which is installed in the slide groove. The dynamic spring pushes the limiting block to slide to abut against the side wall of the slide groove away from the dynamic spring.
[0011] By adopting the above technical solution, the chute provides a sliding path for the limiting block, and the cooperation between the limiting block and the limiting groove can reduce the possibility of the limiting block detaching from the chute. The dynamic spring can push the limiting block to slide to the designated position, ensuring that the limiting block can pass smoothly through the through space when the connecting column is inserted into the connecting groove, thereby enhancing the stability of the connection between adjacent channel components.
[0012] Optionally, the first abutting part and the second abutting part are respectively provided with cement grooves, and the cement grooves are interconnected with the connecting groove; The channel component has a transmission channel that connects the cement troughs on both sides, and the transmission channels of adjacent channel components are far apart from each other.
[0013] By adopting the above technical solution, cement troughs and transmission troughs are set up, and the cement troughs are connected to the connection troughs. This facilitates the injection of cement when connecting adjacent channel components, enhancing the stability of the connection. The transmission troughs of adjacent channel components are far apart from each other, which can reduce cement leakage, improve the overall sealing and seepage prevention performance of the channel, and reduce water resource loss.
[0014] Optionally, the first abutting part is provided with a first sealing ring surrounding the corresponding cement groove; The second abutment portion is provided with a second sealing ring surrounding the corresponding cement trough; When the first abutting part and the second abutting part abut against each other, the first sealing ring and the second sealing ring abut against each other.
[0015] By adopting the above technical solutions, the sealing of the connection parts of adjacent channel components can be enhanced, the possibility of water leakage from the connection parts in the channel can be reduced more effectively, and the seepage prevention performance of the channel can be further guaranteed.
[0016] Optionally, multiple sets of receiving slots are provided on the side wall of the cement tank away from the tank opening, each set of receiving slots corresponds to one connecting slot, and there are multiple receiving slots in each set, arranged around the connecting slot. The channel component is provided with an extrusion plate that slides in the receiving groove, and a push block is hinged to the side wall of the limiting column away from the opening of the connecting groove; When the limiting block slides to abut against the side wall of the limiting post away from the opening of the connecting groove, the limiting block is facing the pushing block; The channel component is equipped with a control component. When cement squeezes the extrusion plate into the receiving groove, the control component controls the pushing block to push the limiting block away from the opening of the connecting groove.
[0017] By adopting the above technical solution, when the cement extrusion plate slides into the receiving groove, the control component controls the pushing block to push the limiting block, thereby further enhancing the stability of the connection between adjacent channel components.
[0018] Optionally, the control component includes a control block, a control spring, and an elastic control rope; The control block slides on the side wall of the receiving groove near the limiting column. The control block is inclined and has a pushing surface. When the extrusion plate slides on the pushing surface, it pushes the control block into the channel component. The control spring is installed inside the channel component, and the control spring pushes the control block to protrude into the receiving groove; The limiting post has a pushing groove on the side wall away from the opening of the connecting groove for accommodating the pushing block. The limiting post is rotatably connected to a hinge shaft located in the pushing groove, and the pushing block is disposed on the outer periphery of the hinge shaft. The elastic control rope is slidably inserted into the channel component and the limiting column. One end of the elastic control rope is connected to the side wall of the control block, and the other end is connected to the outer periphery of the hinge shaft. The elastic control rope is wrapped around the outer periphery of the hinge shaft. When the control block slides out of the receiving groove, the elastic control rope pulls the hinge shaft to rotate.
[0019] By adopting the above technical solution, when the cement extrusion plate slides into the receiving groove, the pushing block can be automatically controlled to push the limiting block away from the opening of the connecting groove, which further enhances the stability of the connection parts of adjacent channel components, reduces the occurrence of misalignment, warping or differential settlement of components, ensures the smoothness of the channel line and the overall sealing and seepage prevention performance, and reduces water resource loss.
[0020] Optionally, the control block has multiple engaging surfaces parallel to the sidewall of the extrusion plate, and multiple pushing surfaces are provided, which are staggered and connected to each other.
[0021] By adopting the above technical solution, the snap-fit surface is parallel to the side wall of the extrusion plate, and the pushing surface is staggered with the snap-fit surface, which can reduce the possibility of the extrusion plate sliding towards the opening of the receiving groove.
[0022] Optionally, the first abutting part is provided with a connecting seat, and the connecting post is threadedly connected to the connecting seat.
[0023] By adopting the above technical solutions, the installation and disassembly of the connecting columns are facilitated, improving construction flexibility and maintenance convenience.
[0024] In summary, this application includes at least one of the following beneficial effects: 1. The structure of connecting column inserted into connecting groove, limiting column abutting against the outer peripheral side wall of connecting column, and limiting block abutting against the side wall of limiting column away from the opening of connecting groove, etc., makes the connection between adjacent channel components stable and reduces the occurrence of misalignment, warping or differential settlement of components when backfilling soil, mechanical rolling or uneven settlement of foundation. 2. No additional complex support and formwork systems are needed to temporarily fix the components, reducing construction costs and complexity and leveraging the efficiency advantages of prefabricated assembly construction.

Detailed Implementation
[0027] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.
[0028] This application discloses a construction structure for farmland irrigation canals.
[0029] Example 1 See Figure 1 and Figure 2 This application provides a construction structure for a farmland irrigation canal, including canal components 1. Multiple canal components 1 are evenly arranged along the canal's extension direction. During construction, a canal trench is first excavated on the ground along the canal's extension direction. Then, a foundation layer and an impermeable layer are laid on the trench walls, and finally, the canal components 1 are installed within the trench. The opposite ends of the canal components 1 along the canal's extension direction are a first abutment portion 2 and a second abutment portion 3, respectively. During installation, adjacent canal components 1 abut against each other through the first abutment portion 2 and the second abutment portion 3, allowing the canal components 1 to be connected sequentially to form a canal, ensuring the continuity and integrity of the canal.
[0030] See Figure 2 and Figure 3The construction structure also includes connecting columns 4, limiting columns 32, mounting columns 5, limiting blocks 51, bearing columns 41, and driving columns 42. Specifically, in this embodiment, the channel component 1 forms a U-shaped groove with the opening facing upwards. In other embodiments, the channel component 1 may also form a rectangular groove with the opening facing upwards. A connecting seat 22 is embedded and fixed on the first abutment portion 2. Multiple connecting seats 22 are evenly spaced along the contour extension trajectory of the first abutment portion 2. There are multiple connecting columns 4, each corresponding to a connecting seat 22. The connecting columns 4 are threadedly connected to the connecting seats 22, allowing the connecting columns 4 to be disassembled. The connecting columns 4 may be made of metal, such as stainless steel or aluminum alloy, to ensure their strength and corrosion resistance; or they may be made of high-strength plastic to reduce weight and cost.
[0031] The second abutting part 3 has a connecting groove 31, which corresponds to the connecting post 4. When the first abutting part 2 and the second abutting part 3 abut against each other, the connecting post 4 is inserted into the connecting groove 31, and there is a gap between the outer peripheral side wall of the connecting post 4 and the peripheral side wall of the connecting groove 31.
[0032] The limiting posts 32 are fixedly connected to the wall of the connecting groove 31, and multiple limiting posts 32 are evenly spaced circumferentially. When the connecting post 4 is inserted into the connecting groove 31, the ends of the limiting posts 32 abut against the outer peripheral sidewall of the connecting post 4. The limiting posts 32 can be made of iron or cement. The function of the limiting posts 32 is to initially position and restrict the connecting post 4, reduce the possibility of the connecting post 4 shaking in the connecting groove 31, and help enhance the stability of the connection.
[0033] See Figure 3 and Figure 4 One end of the mounting column 5 is fixedly connected to a rotating shaft, which is rotatably connected to the end of the connecting column 4 away from the channel component 1. The mounting column 5 and the connecting column 4 are coaxially arranged, and the diameter of the mounting column 5 is less than or equal to the diameter of the connecting column 4. Multiple limiting blocks 51 are slidably connected to the outer periphery of the mounting column 5, evenly spaced circumferentially. The mounting column 5 is equipped with an elastic power component, which can be a power spring 52 or an elastic rubber block, etc. The elastic power component drives the limiting block 51 to slide until its end facing away from the elastic power component abuts against the mounting column 5, forming a passage space 321 between adjacent limiting columns 32 for the limiting block 51 to slide through. This structure allows the mounting column 5 to rotate relative to the connecting column 4 under the action of the elastic power component while the limiting block 51 passes through the passage space 321. When the limiting block 51 moves to the side of the limiting column 32 near the mounting column 5, it is driven to slide to abut against the side wall of the limiting column 32 near the mounting column 5, further restricting the connection between the connecting column 4 and the connecting groove 31.
[0034] See Figure 5 and Figure 6In this embodiment, the elastic power component is a power spring 52, and a sliding groove 54 is provided on the outer periphery of the mounting column 5. There are multiple sliding grooves 54, each corresponding to a limiting block 51. The sliding grooves 54 extend circumferentially and are used for sliding the limiting block 51.
[0035] See Figure 3 Limiting grooves 541 are formed on the opposite sides of the sliding groove 54. A limiting block 511 is fixedly connected to the side wall of the limiting block 51, and the limiting block 511 slides within the limiting groove 541. The setting of the limiting block 511 and the limiting groove 541 can reduce the possibility of the limiting block 51 disengaging from the sliding groove 54 during the sliding process, thus ensuring the stability of the sliding of the limiting block 51.
[0036] See Figure 6 A power spring 52 is installed within a slide groove 54. One end of the power spring 52 abuts against a limiting block 51, and the other end abuts against the wall of the slide groove 54. When the power spring 52 is released elastically, it drives the limiting block 51 to slide within the slide groove 54 until the limiting block 51 abuts against the slide groove 54 and moves away from the driving spring 44 (the driving spring 44 is in...). Figure 3 On one side of the tank wall (marked out).
[0037] See Figure 3 A bearing groove 45 is provided inside the connecting column 4, extending circumferentially from the mounting column 5 to the outside of the connecting column 4. The bearing column 41 slides circumferentially within the bearing groove 45. The bearing column 41 has a square column structure, and the bearing groove 45 is adapted to fit the bearing column 41. A stop block is fixedly connected to the outer periphery of the bearing column 41, and a stop groove is provided on the groove wall of the bearing groove 45. The stop block slides within the stop groove, restricting the sliding trajectory of the bearing column 41.
[0038] The drive column 42 is fixedly connected to one end of the bearing column 41 near the mounting column 5. The drive column 42 is axially slidably connected to the mounting column 5 and the connecting column 4. The drive column 42 is a cylindrical structure. The drive column 42 and the mounting column 5 are rotatably connected and coaxially arranged.
[0039] See Figure 2 and Figure 3A drive ball 43 is fixedly connected to the outer periphery of the drive column 42. A drive groove 53 is provided inside the mounting column 5, extending along a spiral trajectory, and the drive ball 43 slides within the drive groove 53. The connecting column 4 is provided with an elastic drive element, which can be a drive spring 44 or an elastic rubber strip, etc. In this embodiment, the elastic drive element is a drive spring 44, which is installed in the bearing groove 45. One end of the drive spring 44 abuts against the end of the bearing column 41 away from the drive column 42, and the other end abuts against the groove wall of the bearing groove 45. When the drive spring 44 is released elastically, the drive bearing column 41 slides away from the channel component 1, causing the drive column 42 to protrude into the mounting column 5. At this time, the drive ball 43 slides away from the channel component 1 in the drive groove 53, driving the mounting column 5 to rotate until the stop block abuts against the groove wall near the mounting column 5, at which point the limiting block 51 aligns with the through space 321.
[0040] See Figure 3 and Figure 4 When the connecting post 4 is inserted into the connecting groove 31 and the limiting block 51 slides into the through space 321, the driving post 42 abuts against the groove wall of the connecting groove 31 on the side away from the groove opening. When the connecting post 4 continues to be inserted into the connecting groove 31, the groove wall of the connecting groove 31 pushes the driving post 42 to slide into the mounting post 5. At this time, the driving ball 43 slides towards the channel component 1 in the driving groove 53, causing the mounting post 5 to rotate. At this time, the limiting block 51 abuts against the limiting post 32, so that the limiting block 51 slides in the sliding groove 54 and squeezes the power spring 52 until the limiting block 51 moves to the side of the limiting post 32 away from the channel component 1. Then the power spring 52 is released elastically, pushing the limiting block 51 to slide to the side of the limiting post 32 away from the channel component 1.
[0041] See Figure 1 and Figure 2 The first abutment part 2 and the second abutment part 3 are each provided with a cement trough 11. The cement trough 11 extends along the contour of the end of the channel trench and is interconnected with the connecting groove 31. The channel component 1 is provided with a transmission groove 12, which connects the cement troughs 11 on both sides. The transmission grooves 12 of adjacent channel components 1 are far apart from each other and are located near the top wall of the cement trough 11. The cement troughs 11 and the transmission grooves 12 facilitate the injection of cement at the connection point. When the channel component 1 is installed, cement is poured in through the transmission groove 12 of the channel component 1 at one end. The cement then flows into the cement trough 11 and is then transferred to the transmission groove 12 of the next channel component 1 through the cement trough 11. This process continues until the cement flows out from the transmission groove 12 of the channel component 1 at the other end. After that, the transmission grooves 12 of the channel components 1 at both ends are sealed.
[0042] A first sealing ring 21 is embedded and fixed in the first abutment part 2, and the first sealing ring 21 surrounds the corresponding cement groove 11. A second sealing ring 33 is fixedly connected to the second abutment part 3, and the second sealing ring 33 surrounds the corresponding cement groove 11. When the first abutment part 2 and the second abutment part 3 abut against each other, the first sealing ring 21 and the second sealing ring 33 abut against each other. The first sealing ring 21 and the second sealing ring 33 can be made of rubber, which has good sealing performance, can reduce the possibility of cement and water leakage, and is conducive to further improving the seepage prevention performance of the channel.
[0043] See Figure 3 Multiple sets of receiving slots 13 are formed on the side wall of the cement trough 11 away from the opening. Each set of receiving slots 13 corresponds to a connecting slot 31, and there are multiple receiving slots 13 in each set, arranged around the connecting slot 31. The channel component 1 is provided with an extrusion plate 6, which slides in the receiving slot 13, and the peripheral sidewall of the extrusion plate 6 is slidably connected to the peripheral sidewall of the receiving slot 13. A pushing slot 323 is formed on the side wall of the limiting post 32 away from the opening of the connecting slot 31. The limiting post 32 is rotatably connected to a hinge shaft 324, which is located in the pushing slot 323. A pushing block 322 is fixedly connected to the outer periphery of the hinge shaft 324, and the pushing block 322 is accommodated in the pushing slot 323. When the limiting block 51 slides to abut against the side wall of the limiting post 32 away from the opening of the connecting slot 31, the limiting block 51 is directly opposite the pushing block 322.
[0044] See Figure 2 and Figure 3 The channel component 1 is equipped with a control component 7. When the cement extrusion plate 6 slides into the receiving groove 13, the control component 7 controls the push block 322 to push the limiting block 51 away from the opening of the connecting groove 31. The control component 7 is designed so that after cement is injected, the continuous injection of cement extrudes the extrusion plate 6, causing the control component 7 to control the push block 322 to push the limiting block 51 away from the opening of the connecting groove 31, thereby further enhancing the connection stability between the connecting column 4 and the connecting groove 31.
[0045] The control assembly 7 includes a control block 71, a control spring 72, and an elastic control rope 73. A sliding groove is formed on the side wall of the receiving groove 13 near the limiting post 32, and the control block 71 slides within the sliding groove. The control spring 72 is installed within the sliding groove, with one end abutting against the side of the control block 71 near the limiting post 32, and the other end abutting against the side wall of the sliding groove away from the opening. When the control spring 72 is released elastically, it pushes the control block 71 to slide and protrude into the receiving groove 13. The control block 71 has an inclined pushing surface 711; when the pressing plate 6 slides on the pushing surface 711, it pushes the control block 71 into the channel component 1. The control block 71 has multiple engaging surfaces 712, which are parallel to the side wall of the pressing plate 6 near the limiting post 32. Multiple pushing surfaces 711 are interleaved and connected to the engaging surfaces 712. By setting multiple snap-fit surfaces 712, when the pressing plate 6 slides to abut the snap-fit surface 712, the pressing plate 6 can restrict the control block 71 from sliding into the receiving groove 13.
[0046] The elastic control rope 73 is slidably inserted into the channel component 1 and the limiting post 32. One end of the elastic control rope 73 is fixedly connected to the side wall of the control block 71, and the other end is fixedly connected to the outer periphery of the hinge shaft 324. The elastic control rope 73 is wound around the outer periphery of the hinge shaft 324. When the control block 71 slides into the sliding groove, the elastic control rope 73 pulls the hinge shaft 324 to rotate. This structure controls the movement of the control block 71 by sliding the extrusion plate 6, and then pulls the hinge shaft 324 to rotate by the elastic control rope 73, thereby realizing the pushing block 322 pushing the limiting block 51, further enhancing the stability of the connection. In other embodiments, before the limiting block 51 slides to the side of the limiting post 32 away from the channel component 1, in order to keep the pushing block 322 in the state of the pushing groove 323, magnets with opposite magnetic properties can be fixed on the pushing block 322 and the groove wall of the pushing groove 323 respectively. The magnets with opposite magnetic properties attract each other, so that the pushing block 322 is in the pushing groove 323.
[0047] The implementation principle of a construction structure for a farmland canal according to an embodiment of this application is as follows: By inserting the connecting column 4 into the connecting groove 31, the limiting column 32 initially positions the connecting column 4. After passing through the through space 321, the limiting block 51 slides to abut against the limiting column 32 on the side away from the channel component 1, improving the connection stability between the channel components 1 and reducing the possibility of misalignment between the channel components 1 during construction. At the same time, the setting of the cement trough 11, transmission trough 12, sealing ring, extrusion plate 6, pushing block 322 and control component 7 further enhances the sealing and stability of the connection, effectively solving the problem of unstable connection of existing prefabricated farmland channel components 1, improving the overall sealing and seepage prevention performance of the channel, and reducing water loss.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
