Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, specifically to a spliced ​​road and canal structure. Background Technology

[0002] In the construction of existing roads and drainage facilities, a separate design of "road + independent ditch" is usually adopted. This model has many drawbacks: First, it wastes land resources, as roads and ditches occupy land independently, and the area between them is difficult to utilize effectively, resulting in a significant reduction in the actual cultivated area of ​​farmland. Second, the construction cycle is long, requiring multiple processes such as road base paving, pavement pouring, and ditch excavation and lining, making coordination of cross-operations difficult. Third, the project cost is high, as separate construction leads to low material consumption, labor input, and machinery utilization efficiency, and the junction of ditches and roads is prone to damage due to uneven settlement, increasing later maintenance costs. Fourth, it has poor adaptability, as traditional cast-in-place ditches cannot be adjusted after completion. When the road alignment or drainage requirements change, the modification is extremely difficult, and demolition and reconstruction will generate a large amount of construction waste.

[0003] While existing prefabricated and assembled ditches offer some improvement in construction efficiency, they mostly only provide drainage and cannot be integrated with the road structure. Therefore, there is an urgent need to improve the existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, a modular road and ditch structure is proposed, which solves the problem that the modular ditches in the aforementioned technologies only have a single drainage function and cannot be integrated with the road structure.

[0005] To achieve the above objectives, the present invention proposes the following technologies: A spliced ​​road and canal structure includes a road and canal section. At both ends of the road and canal section, a first splicing part and a second splicing part are respectively provided for connecting adjacent road and canal sections. The road and canal section includes two road and canal units. The road and canal units are provided with a conveying channel for irrigation and drainage, and a water conveying hole connecting the conveying channel.

[0006] Furthermore, the road channel unit includes a main cylinder, the interior of which is hollow to form a conveying channel, and a horizontal top plate is provided on the top of the main cylinder as a road layer to form a road surface.

[0007] Furthermore, a support plate and a side plate are respectively provided on both sides of the top plate, and the water inlet is opened on the side plate. A bottom plate is also provided below the top plate to connect the support plate and the side plate from below, thereby forming a closed conveying channel.

[0008] Furthermore, the first splicing part is specifically a splicing ring, and the top plate, side plate and bottom plate form a support frame. One end of the support frame is provided with a splicing layer that is flush with the outer surface of the main body tube. The two splicing layers are spliced ​​together to form a splicing ring so as to facilitate splicing with the second splicing part.

[0009] Furthermore, the second splicing part is specifically a splicing joint. The other end of the support frame is provided with a splicing step. The height of the splicing step matches the thickness of the splicing layer. The two splicing steps are spliced ​​together to form a splicing joint so that it can be inserted into the splicing groove formed by the splicing ring, thereby realizing the splicing of adjacent road and canal sections.

[0010] Furthermore, the support plate is located inside the conveying channel, and the support plate is provided with horizontally distributed splicing grooves and splicing blocks. The road and channel unit is spliced ​​with another road and channel unit through the splicing grooves and splicing blocks.

[0011] Furthermore, the support plate is provided with a fixing groove, and the fixing grooves on two road and ditch units in the road and ditch section are joined together to form a fixing hole, which is used to insert a fixing column to increase the joint strength.

[0012] Furthermore, a sliding groove is provided on the side plate, the sliding groove extends to the ground and forms an insertion interface on the top plate, the water inlet hole passes through the sliding groove, and a baffle for controlling the size of the water inlet hole opening is slidably connected inside the sliding groove.

[0013] Furthermore, the side plate is inclined, and the longitudinal sections of the splicing groove and the splicing block are respectively isosceles trapezoidal. The width of the splicing groove is greater than that of the splicing block to form a gap for filling with sealing material.

[0014] Compared with the prior art, the comprehensive effects brought about by this utility model include: This application integrates traditional road and canal functions into a prefabricated module by setting up basic unit road-canal sections. The top of each road-canal section serves as the road layer, facilitating traffic, while the internal conveying channels handle water transport. This saves land resources, maximizing the functional efficiency per unit area. The modular prefabrication and on-site assembly construction method effectively improves construction efficiency, significantly shortens the construction period, and substantially reduces labor and machinery costs. Furthermore, prefabrication ensures the uniformity of component quality, overall structural stability, and low maintenance costs. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] This embodiment describes in detail a modular road-ditch structure. This structure aims to solve the problems of land waste, complex construction, high cost, and poor adaptability caused by the traditional separate construction of roads and ditches.

[0020] like Figures 1 to 6 As shown, a spliced ​​road and canal structure includes a road and canal section 1. The two ends of the road and canal section 1 are respectively provided with a first splicing part 2 and a second splicing part 3 for connecting adjacent road and canal sections 1. The road and canal section 1 includes two road and canal units 4. The road and canal units 4 are provided with a conveying channel 5 for irrigation and drainage, and a water conveying hole 6 connecting the conveying channel 5.

[0021] The basic building block of this application is the road-canal section 1, which integrates the traditional road and canal functions into a prefabricated module. Specifically, the top of each road-canal section 1 serves as a road layer, assuming the function of passage; while the conveying channel 5 formed inside it assumes the function of water conveyance.

[0022] The integrated design described above significantly conserves land resources, eliminates the dividing zone between roads and independent ditches, and maximizes the functional efficiency per unit area of ​​land, making it particularly suitable for high-standard farmland construction areas where land resources are scarce. Secondly, the modular prefabrication and on-site assembly construction methods effectively improve construction efficiency. On-site operations are simplified to foundation treatment and module assembly, avoiding complex cast-in-place processes, greatly shortening the construction period, and significantly reducing labor and machinery costs. Furthermore, prefabrication ensures the uniformity of component quality, overall structural stability, and low maintenance costs in the later stages.

[0023] In the spliced ​​road and ditch structure of this embodiment, the road and ditch unit 4 includes a main cylinder 7. The interior of the main cylinder 7 is hollow to form a conveying channel 5. The top of the main cylinder 7 is provided with a horizontal top plate 8 as a road layer to form a road surface.

[0024] Each road and canal section 1 is assembled from two road and canal units 4 that are arranged side by side along its length and have basically the same structure. This reduces the size and weight of individual prefabricated components, thereby reducing production difficulty, transportation costs, and on-site hoisting requirements.

[0025] The modular design enhances the adaptability and flexibility of the structure, allowing for flexible adjustment of individual unit sizes based on changes in flow requirements, or independent replacement of units during future renovations without affecting the overall structure. Finally, compared to large, monolithic prefabricated components, modular prefabrication reduces the risk of cracking due to shrinkage and deformation, and increases the yield rate.

[0026] Preferably, the main cylinder 7 serves as the supporting structure for the irrigation and drainage flow conveying channel 5, and also provides a supporting foundation for the road layer. It is cast using high-strength concrete mixed with fiber-reinforced materials.

[0027] In the spliced ​​road channel structure of this embodiment, a support plate 9 and a side plate 10 are respectively provided on both sides of the top plate 8. The water conveying hole 6 is opened on the side plate 10. A bottom plate 11 is also provided below the top plate 8 to connect the support plate 9 and the side plate 10 from below, thereby forming a closed conveying channel 5.

[0028] Specifically, the main tube 7 includes a road layer (channel top plate 8), a channel bottom plate 11, a channel side plate 10, and a support plate 9. The side plate 10 is inclined, so that the cross section of the main tube 7 is a right trapezoid.

[0029] The road layer (channel top plate 8) is prefabricated on the top of the channel body and the surface is treated with anti-slip treatment (such as anti-slip texture) to meet the load requirements of agricultural machinery and personnel passage; the channel bottom plate 11 is prefabricated at the bottom of the channel body and the channel side plate 10 is prefabricated on the side of the channel body.

[0030] Preferably, a seepage-proof layer is set on the inner side of the channel body and a seepage-proof layer is set on the road layer. High-density polyethylene (HDPE) geomembrane with a thickness of 1.0-1.5mm can be used. The geomembrane joints are hot-melt welded, and the welding strength is not lower than the strength of the parent material.

[0031] In the spliced ​​road and channel structure of this embodiment, the first splicing part 2 is specifically a splicing ring. The top plate 8, the side plate 10 and the bottom plate 11 form a support frame. One end of the support frame is provided with a splicing layer 12 that is flush with the outer surface of the main tube 7. The two splicing layers 12 are spliced ​​together to form a splicing ring so as to facilitate splicing with the second splicing part 3.

[0032] Correspondingly, the second splicing part 3 is specifically a splicing joint. The other end of the support frame is provided with a splicing step 13. The height of the splicing step 13 matches the thickness of the splicing layer 12. The two splicing steps 13 are spliced ​​together to form a splicing joint so that it can be inserted into the splicing groove formed by the splicing ring, thereby realizing the splicing of adjacent road and canal sections 1.

[0033] To achieve a rapid and reliable connection between the road and canal sections 1, this application designs a specific splicing structure. At one end of the support frame formed by the top plate 8, side plates 10, and bottom plate 11, a splicing layer 12 is formed flush with the outer wall of the main cylinder 7. The splicing layers 12 of the two road and canal units 4 together form a ring-shaped first splicing part 2 (splicing ring). At the other end of the support frame, the ends of the top plate 8, side plates 10, and bottom plate 11 are recessed to form a splicing step 13. The splicing steps 13 of the two road and canal units 4 together form a second splicing part 3 (splicing joint).

[0034] Specifically, the splicing layer 12 is composed of the following structure: one end of the road layer (channel top plate 8) is flush with the outer side of the channel as the upper top plate; one end of the channel bottom plate 11 is flush with the outer side of the channel as the upper bottom plate; and one end of the channel side plate 10 is flush with the outer side of the channel as the upper side plate. The splicing step 13 includes: the other end of the road layer (channel top plate 8) is flush with the inner side of the channel as the lower top plate; the other end of the channel bottom plate 11 is flush with the inner side of the channel as the lower bottom plate; and the other end of the channel side plate 10 is flush with the inner side of the channel as the lower side plate.

[0035] The upper layer of the top plate, the upper layer of the side plate, and the upper layer of the bottom plate of the channel form a receiving structure, i.e., a splicing ring, at one end of the channel body. The lower layer of the top plate, the lower layer of the side plate, and the lower layer of the bottom plate form an insertion structure, i.e., a splicing joint, at the other end of the channel body. The two road and channel sections 1 are connected through the insertion structure and the receiving structure.

[0036] The use of a socket-type connection method with "splitting rings" and "joints" enables rapid axial positioning and installation, making construction extremely simple and precise. The splicing ring effectively encloses and constrains the joint, allowing for reliable transmission of axial loads at the connection and enhancing the longitudinal integrity of the roadway and canal. Simultaneously, this large-area annular contact surface provides excellent conditions for applying sealing materials, effectively preventing leakage at the joint and ensuring water conveyance efficiency.

[0037] In the splicing road and canal structure of this embodiment, the support plate 9 is located inside the conveying channel 5. The support plate 9 is provided with horizontally distributed splicing grooves 14 and splicing blocks 15. The road and canal unit 4 is spliced ​​with another road and canal unit 4 through the splicing grooves 14 and splicing blocks 15.

[0038] Within the same canal section 1, two parallel canal units 4 are laterally connected by their opposing support plates 9. Specifically, a splicing block 15 is set on one support plate 9, and a splicing groove 14 is set at the corresponding position on the other support plate 9. The two units are laterally spliced ​​by the splicing block 15 sliding into the splicing groove 14. The cross-section of the canal section 1 is an inverted trapezoidal structure. The spliced ​​canal section 1 has two parallel conveying channels 5. The canal section 1 is the smallest unit of the double-hole channel. The final canal is formed by splicing the canal sections 1 together, which can simultaneously irrigate and drain the farmland on both sides.

[0039] The above-described setup enables precise positioning and initial fixation of the two road and canal units 4 when they are joined together. This mortise and tenon structure effectively resists lateral shear forces, preventing relative misalignment or separation of the two units during use, ensuring that they are tightly combined into a stable, integrated road and canal section 1, jointly bearing the vehicle load from above and the lateral earth pressure.

[0040] The support plate 9 serves as the load-bearing structure of the road and is equipped with tenons and grooves. The tenons and grooves extend horizontally through the entire support plate 9. The longitudinal sections of the splicing groove 14 and the splicing block 15 are respectively isosceles trapezoids. The width of the splicing groove 14 is greater than that of the splicing block 15 to form a gap for filling with sealing material.

[0041] Preferably, the width of the splicing block 15 is 2-3mm narrower than the splicing groove to reserve space for sealing material filling. The top of the splicing block 15 is provided with a guide slope to facilitate quick positioning during docking.

[0042] By filling with sealing material, all leakage paths at the transverse joints of the two road and canal units 4 were sealed off. This not only prevents water resources from being lost from the joints and improves water conveyance efficiency, but also effectively avoids the soaking and erosion of the roadbed soil by seepage, thereby ensuring the long-term stability of the roadbed and the durability of the entire road and canal structure. This is a key detail to ensure the long-term reliable operation of the integrated structure.

[0043] In the spliced ​​road and ditch structure of this embodiment, the support plate 9 is provided with a fixing groove, and the fixing grooves on the two road and ditch units 4 in the road and ditch section 1 are spliced ​​together to form a fixing hole 16. The fixing hole 16 is used to insert a fixing post 17 to increase the splicing strength.

[0044] To further enhance the strength of the lateral connection, a fixing groove is made on the support plate 9. When two road and ditch units 4 are assembled by splicing blocks 15 and splicing grooves 14, their respective fixing grooves are aligned to form a complete fixing hole 16 that runs through the road and ditch section 1. During construction, a prefabricated fixing column 17 (e.g., a concrete column or steel column with a triangular cross section) is inserted into the fixing hole 16, providing a strong rigid shear-resistant connection.

[0045] The fixed column 17 acts as a "pin," firmly locking the two road and canal units 4 together, greatly enhancing the overall rigidity and deformation resistance of the road and canal section 1. This is crucial for bearing the loads of heavy agricultural machinery and adapting to possible uneven foundation settlement, effectively preventing damage at the joint due to stress concentration, and ensuring the long-term safety and stability of the structure.

[0046] In the spliced ​​road and ditch structure of this embodiment, a sliding groove 18 is provided on the side plate 10. The sliding groove 18 extends to the ground and forms an insertion interface on the top plate 8. The water inlet 6 passes through the sliding groove 18. A baffle 19 for controlling the opening size of the water inlet 6 is slidably connected inside the sliding groove 18.

[0047] To achieve flexible control of the water flow, a groove 18 is provided on the side plate 10, which extends from the upper surface of the top plate 8 to the lower surface. The water inlet 6 passes through this groove 18, and the baffle 19 is placed inside the groove 18 and can slide up and down.

[0048] The sliding baffle 19 enables convenient and precise control of the water flow from each water inlet 6. Management personnel can adjust the water flow cross-section directly on the road surface by raising or lowering the baffle 19 without entering the canal, achieving precise irrigation and drainage management. This design is safe, simple, and efficient, significantly reducing the labor intensity and risks of daily management. The water inlets 6 and baffle 19 can also serve as dredging and maintenance access points, facilitating maintenance.

[0049] In practice, a 1m deep trench with a width of no less than 2m is dug on the installation ground. Graded sand and gravel are laid in layers at the bottom of the trench and compacted by vibration to form a stable trench bottom.

[0050] Multiple road and canal segments 1 are spliced ​​together to form a final channel through the combination of insertion and receiving structures. The channel interface is an inverted trapezoidal double channel.

[0051] The upper surface of the road layer (channel top plate 8) is provided with anti-slip texture. Agricultural machinery and personnel pass through the channel top plate 8, keeping the road surface slightly higher than the farmland level.

[0052] Specifically, this application also includes a canal section 1 without water conveyance holes 6, which facilitates the splicing of canal sections 1 without water conveyance holes 6 between canal sections 1 with water conveyance holes 6 according to irrigation or drainage needs. For example, water conveyance holes 6 can be installed every 100m, at the middle height of the canal side plate 10, and equipped with baffles 19 to ensure that the bottom of the water conveyance hole 6 is at the same height as the field surface. The height of the baffles 19 determines the amount of irrigation and drainage. During irrigation, water is delivered to the farmland through the water conveyance holes 6; during drainage, accumulated water in the farmland is discharged through the water conveyance holes 6, ensuring irrigation during droughts and drainage during floods. When it is necessary to adjust the irrigation and drainage or maintain the facilities, operators can open the baffles 19 to dredge and repair the canal.

[0053] On the outside of the channel side plate 10, where there is no water inlet 6, backfill with excavated soil and compact it.

[0054] In summary, the integrated road and irrigation channel structure proposed in this application achieves efficient integration of roads and irrigation channels, and has significant advantages such as saving land, reducing costs, facilitating maintenance, and integrating functions. It is suitable for large-scale promotion and application in farmland water conservancy projects.
