[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process.

[0024] In the existing technology, precast trenches need to be connected end to end using other connecting components, which is inconvenient to assemble. Moreover, after long-term use, the tensile stress generated by external loads can easily cause cracks in the precast trenches, affecting their durability and impermeability.

[0025] In view of this, the present invention provides a prefabricated precast ditch, which is assembled quickly and stably from end to end using S-shaped connecting ends and beak-shaped connecting ends. The assembly joints of the precast ditch are treated with water-stopping and seepage prevention, and a slope structure is poured inside the prefabricated precast ditch to improve the drainage effect and seepage resistance of the ditch, effectively enhancing the sealing and stability of the ditch connection. At the same time, the use of steel strands to generate pre-compression stress inside the precast ditch can offset the tensile stress generated by external loads, which can significantly reduce or even eliminate cracks in the ditch components, ensuring that the ditch components have sufficient strength and durability. This helps to improve the overall waterproof performance and service life of the prefabricated precast ditch.

[0026] Depend on Figure 1 and Figure 2 As can be seen, the prefabricated ditch in this case includes a component base plate 1, with component side plates 2 on both sides of the top of the component base plate 1. The prefabricated ditch also includes an assembly structure 3, a prestressed anchor assembly 4, and a slope structure 5. The assembly structure 3 is located at both ends of the component base plate 1 and the component side plates 2; the prestressed anchor assembly 4 is located on the side of the component base plate 1 and the component side plates 2 that are close to each other; and the slope structure 5 is located on the top of the component base plate 1. The prefabricated ditch is assembled end to end by the assembly structure 3, and the prestressed anchor assembly 4 is used to offset the tensile stress generated by the external load on the component base plate 1 and the component side plates 2, thereby improving the load-bearing capacity of the ditch components and significantly reducing or even eliminating cracks. The slope structure 5 improves the drainage effect, seepage resistance, and structural stability of the ditch.

[0027] In the specific implementation process, it is worth noting that the component base plate 1 and component side plate 2 are made of high-strength precast concrete to form an integrated ditch structure. They are assembled end to end through the assembly structure 3, and the prestressed anchor assembly 4 is used to offset the tensile stress generated by the external load on the component base plate 1 and component side plate 2. By setting the slope structure 5 on the inner bottom of the precast ditch, the load-bearing capacity and drainage effect of the ditch components are improved, cracks are significantly reduced or even eliminated, and the impermeability and structural stability of the ditch are improved.

[0028] In one feasible approach, please refer to Figure 1 and Figure 2 The assembly structure 3 includes a connecting structure 31, a water-stopping structure 32, and a sealing assembly 33. The connecting structure 31 is located at both ends of the component side plate 2; the water-stopping structure 32 is located at both ends of the component side plate 2; and the sealing assembly 33 is located at the top of the component side plate 2. The connecting structure 31 is used to assemble the prefabricated ditch, and the water-stopping structure 32 is used to stop water and prevent seepage at the assembly connection of the prefabricated ditch. The sealing assembly 33 seals the top of the prefabricated ditch to prevent external moisture or impurities from entering the prefabricated ditch and improve the safety of water supply and irrigation.

[0029] In the specific implementation process, it is worth noting that adjacent prefabricated ditches are connected end to end through the connecting structure 31, the water-stopping structure 32 improves the water-stopping and seepage prevention performance at the assembly connection, and the top of the prefabricated ditch is sealed by the cover assembly 33 to improve the safety of water supply and irrigation.

[0030] In one feasible approach, please refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 The connecting structure 31 includes an S-shaped connecting end 311 and a beak connecting end 312. The S-shaped connecting end 311 is located at one end of the two component side plates 2; the beak connecting end 312 is located at the end of the two component side plates 2 away from the S-shaped connecting end 311. The S-shaped connecting end 311 and the beak connecting end 312 are respectively located at both ends of the ditch component. The prefabricated ditch components are connected end to end by inserting the S-shaped connecting end 311 into the beak connecting end 312 of the adjacent ditch component.

[0031] In the specific implementation process, it is worth noting that by inserting the S-shaped connecting end 311 into the beak connecting end 312 of the adjacent ditch component, a quick and stable connection of the prefabricated ditch components can be achieved, which effectively improves the sealing and stability of the ditch connection and ensures the good performance of the ditch in long-term use. The cooperative design of the S-shaped connecting end 311 and the beak connecting end 312 simplifies the construction process, further shortens the construction period, and reduces construction costs.

[0032] In one feasible approach, please refer to Figure 3 , Figure 6 and Figure 7 The water-stopping structure 32 includes an S-shaped bevel positioning steel plate 321 and an S-shaped rubber waterstop 322.

The S-shaped bevel positioning steel plate 321 is fixedly connected to the inner side of the beak-shaped connecting end 312 by welding with the pre-embedded steel bars. The S-shaped rubber waterstop 322 is bonded to the concrete surface of the S-shaped connecting end 311. When the S-shaped connecting end 311 is inserted into the beak-shaped connecting end 312, the tightness between the S-shaped rubber waterstop 322 and the S-shaped bevel positioning steel plate 321 keeps the connection between the two ditch components in a water-stopping state, preventing water leakage and improving the overall waterproof performance and service life of the prefabricated ditch.

[0033] In the specific implementation process, it is worth noting that after the prefabricated ditch is assembled, the S-shaped rubber waterstop 322 is pressed against the S-shaped bevel positioning steel plate 321, and the joint is sealed with polyurethane or silicone sealant to keep the connection between the two ditch components in a water-stop state, prevent water leakage, and improve the overall waterproof performance and service life of the prefabricated ditch.

[0034] In one feasible approach, please refer to Figure 2 , Figure 3 and Figure 5 The sealing assembly 33 includes a steel hinge support 331, a top cover plate 332, and a rubber support 333. The steel hinge support 331 is fixedly connected at equal intervals to the top of the component side plate 2 located on one side. The top cover plate 332 is equidistantly disposed above the component side plate 2 and is rotatably connected to the steel hinge support 331. The rubber support 333 is fixedly connected at equal intervals to the top of the component side plate 2 away from the steel hinge support 331 and is connected to the top cover plate 332. The steel hinge support 331 and the rubber support 333 are fixedly connected to the top of the two component side plates 2 respectively by anchor bolts. One side of the top cover plate 332 is rotatably connected to the component side plate 2 through the steel hinge support 331, and the other side of the top cover plate 332 is supported by the rubber support 333, thereby sealing the top of the prefabricated ditch, preventing external moisture or impurities from entering the prefabricated ditch, and improving the safety of water supply and irrigation.

[0035] In the specific implementation process, it is worth noting that the top cover plate 332 is installed on the top of the precast trench through the steel hinge support 331, and the other side of the top cover plate 332 is stably supported by the rubber support 333, so as to ensure that the top cover plate 332 is not easily deformed or loosened during long-term use, thereby sealing the top of the precast trench, preventing external moisture or impurities from entering the precast trench, and facilitating the maintenance and repair of the interior of the precast trench by construction personnel.

[0036] In one feasible approach, please refer to Figure 1 and Figure 4 The prestressed anchor assembly 4 includes an anchoring structure 41 and an anchor fixing assembly 42. The anchoring structure 41 is embedded in the bottom of the component side plate 2. The anchor fixing assembly 42 is disposed at both ends of the anchoring structure 41. The anchoring structure 41 is fixedly connected to the inside of the component side plate 2 through the anchor fixing assembly 42, so as to offset the tensile stress generated by the external load on the component bottom plate 1 and the component side plate 2, thereby improving the load-bearing capacity and service life of the ditch component.

[0037] In the specific implementation process, it is worth noting that by setting an anchoring structure 41 inside the lower part of the component side plate 2, and by using the anchor fixing component 42 to firmly support and position the anchoring structure 41, the component bottom plate 1 and component side plate 2 can offset the tensile stress generated by the external load, and ensure that the anchoring structure 41 is not prone to loosening or failure during long-term use, thereby improving the load-bearing capacity and service life of the ditch component.

[0038] In one feasible approach, please refer to Figure 1 and Figure 4 The anchoring structure 41 includes a corrugated metal pipe 411, steel strands 412, an anchor plate 413, an anchor 414, wedges 415, and a grouting hole 416.

On one side, it is connected to the metal corrugated pipe 411; wherein, the steel strand 412 passes through the metal corrugated pipe 411 and the anchor plate 413, and the steel strand 412 is anchored at both ends of the component side plate 2 by the anchor 414 and the clamp 415, and high-strength grouting material is injected into the metal corrugated pipe 411 through the grouting hole 416 to enhance the bonding force between the steel strand 412 and the metal corrugated pipe 411. The pre-compression stress generated by the steel strand 412 offsets the tensile stress generated by the external load, significantly reducing or even eliminating cracks in the ditch component, and ensuring that the ditch component has sufficient strength and durability.

[0039] In the specific implementation process, it is worth noting that by inserting the steel strand 412 into the metal corrugated pipe 411 and the anchor plate 413, and using the anchor 414 and the clamp 415 to anchor the steel strand 412 at both ends of the component side plate 2, and injecting high-strength grouting material into the metal corrugated pipe 411 through the grouting hole 416, the steel strand 412 generates pre-compression stress inside the precast ditch to offset the tensile stress generated by the external load, significantly reducing or even eliminating cracks in the ditch component, and ensuring that the ditch component has sufficient strength and durability.

[0040] In one feasible approach, please refer to Figure 1 and Figure 4 The anchor fixing assembly 42 includes a spiral rib 421 and mounting holes 422. The spiral rib 421 is connected to the outer wall of the anchor plate 413 and embedded in the component side plate 2. The mounting holes 422 are equidistantly opened on the outer wall of the anchor plate 413. The spiral rib 421 is used to reinforce the anchor plate 413 and improve the connection strength between the anchor plate 413 and the component side plate 2. The mounting holes 422 facilitate the fixing of the anchor plate 413 and the spiral rib 421 to the inside of the component side plate 2 by fasteners such as anchor bolts, ensuring the stability and reliability of the anchoring structure 41 and further improving the overall structural strength and durability of the prefabricated ditch.

[0041] In the specific implementation process, it is worth noting that the anchor plate 413 improves the connection strength between itself and the component side plate 2 through the spiral reinforcement 421, and is fixed by the mounting hole 422, so as to ensure the stability and reliability of the anchoring structure 41 and further improve the overall structural strength and durability of the prefabricated ditch.

[0042] In one feasible approach, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 7 The side plate 2 of the component is provided with fiber optic pre-embedded holes 5.

[0043] In the specific implementation process, it is worth noting that by pre-setting optical fiber embedded holes 5 inside the side plate 2 of the component, damage to the ditch component is avoided, so that the optical fiber is not affected by external interference in the concrete structure, and the information-based monitoring and control of the culvert and water volume measurement are realized.

[0044] Working principle: During the prefabrication of the precast trench, steel strands 412 are inserted into the interior of the corrugated metal pipe 411. Anchors 414 and clamps 415 fix the steel strands 412 at the anchor plate 413. High-strength grouting material is injected into the corrugated metal pipe 411 through the grouting hole 416, generating pre-stress in the steel strands 412 within the precast trench. When external loads generate tensile stress, the pre-stress generated by the steel strands 412 offsets it, reducing or even eliminating cracks in the trench components and improving the durability and impermeability of the precast trench. During assembly, a foundation trench for laying the precast trench is excavated on the ground, a sand cushion layer is laid at the bottom of the trench, and the precast trench is then lifted and placed... At the top of the sand cushion layer, the S-shaped connection end 311 of the precast ditch is inserted into the beak connection end 312 of the adjacent precast ditch to assemble and connect the precast ditch. The S-shaped rubber waterstop 322 located outside the S-shaped connection end 311 is tightly fitted with the S-shaped bevel positioning steel plate 321 located at the beak connection end 312. The joints of the precast ditch are sealed with polyurethane or silicone sealant to improve the assembly efficiency of the precast ditch. After the assembly of the precast ditch is completed, backfill soil is filled into the foundation trench, and the top cover plate 332 is installed on the steel hinge support 331. The top cover plate 332 forms a seal on the top of the precast ditch to prevent external moisture or impurities from entering the precast ditch, thus completing the overall assembly of the precast ditch.
