Description

Technical Field

[0001] This utility model belongs to the field of farmland water conservancy technology, specifically relating to a seepage-proof farmland ditch structure for crop planting. Background Technology

[0002] In crop cultivation, farmland ditches are an important component of irrigation and drainage systems, and their structural stability and seepage prevention performance directly affect the efficiency of farmland water conservancy. Traditional farmland ditches are mostly constructed from prefabricated components, but this presents several problems in practical applications:

[0003] On the one hand, the sealing effect at the joints of precast components is poor. In existing technologies, when connecting two precast ditch components, concrete is usually applied directly to the joint for sealing. However, due to the difference in shrinkage rates between the precast component material and concrete, and the long-term effects of water erosion and soil settlement in farmland environments, cracks easily form at the joints, leading to serious leakage. This not only wastes water resources but also affects crop growth due to abnormal soil moisture content around the ditch, increasing irrigation costs.

[0004] On the other hand, siltation easily occurs in ditches. During farmland irrigation or drainage, the silt carried by the water flow will settle at the bottom of the ditch due to the reduced flow velocity. Over time, this accumulation will reduce the cross-sectional area of ​​the ditch, thus reducing drainage and irrigation efficiency. Traditional ditches lack targeted anti-siltation structures and require regular manual dredging, which not only consumes a lot of manpower and resources but may also affect the normal operation of the farmland water conservancy system if dredging is not done in a timely manner. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a seepage-proof farmland ditch structure for crop cultivation. The specific technical solution is as follows:

[0006] A seepage-proof farmland ditch structure for crop cultivation includes prefabricated ditch components. Each prefabricated ditch component has a staggered connector integrally formed at both ends. When two prefabricated ditch components are spliced ​​together, a zigzag gap is formed at the connection point of the connector. Connecting grooves are provided on the upper and lower surfaces of both ends of the prefabricated ditch components. A cast-in-place component is cast between the two prefabricated ditch components, and the cast-in-place component wraps around the upper part of the connector and fills the connecting groove. A downwardly recessed sludge discharge groove is provided in the middle of the prefabricated ditch component, and a detachable flow-blocking component is provided in the middle of the prefabricated ditch component.

[0007] Preferably, the cast-in-place component includes a cast-in-place slab located above the connector, a cast-in-place bend line located in the bend line gap, and a cast-in-place column located in the connecting groove. The cast-in-place slab, the cast-in-place bend line, and the cast-in-place column are integrally formed, and the cast-in-place slab and the cast-in-place bend line are fitted together to wrap around the upper part of the connector.

[0008] Preferably, the connector is an isosceles trapezoidal structure.

[0009] Preferably, the sludge discharge trough has a "V" shaped structure.

[0010] Preferably, the flow obstruction component includes two guide strips integrally formed on the inner surface of the prefabricated ditch component, and a water baffle is inserted between the two guide strips. The water baffle is provided in four sections, and the four water baffles are isosceles trapezoidal structures.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By using the staggered connectors integrally formed at both ends of the precast trench components, a zigzag gap is created when the two components are spliced, providing reasonable space for the cast-in-place component. The cast-in-place component not only wraps around the upper part of the connector but also fills the connecting groove, forming a multi-dimensional interlocking structure. This design significantly increases the connection area and interlocking force between the precast and cast-in-place components, avoiding the defects of traditional splicing methods that rely solely on concrete sealing, which are prone to cracking. This fundamentally improves the sealing reliability of the splice, significantly reduces the risk of leakage, saves water resources, and ensures the stability of the farmland irrigation system.

[0013] 2. The staggered connectors, combined with the cast-in-place components, create a robust integrated structure between the two precast ditch components, effectively resisting external forces such as soil settlement and water flow impact. Compared to traditional simple splicing structures, this design, through the double interlocking of the zigzag gap and connecting groove, significantly improves the overall deformation resistance of the ditch and extends its service life.

[0014] 3. The sludge discharge trough in the middle of the prefabricated ditch component works in conjunction with the detachable flow-blocking component to form a dynamic anti-siltation system. The flow-blocking component can adjust the water flow area according to the water flow conditions. While ensuring normal irrigation and drainage, it increases the local flow velocity by reducing the water flow cross-section, allowing silt to be smoothly discharged with the water flow and reducing deposition. The detachable design allows for flexible adjustment according to the water flow requirements of different crop planting stages, which reduces dredging costs while maintaining the efficient water flow capacity of the ditch.

[0015] 4. By addressing leakage and siltation issues, this structure ensures precise delivery of irrigation water, reducing water waste and the risk of secondary soil salinization. Simultaneously, its stable drainage capacity effectively copes with extreme weather events such as torrential rains, reducing the probability of farmland flooding. Overall, it optimizes the operational efficiency of the farmland irrigation system, providing a stable water environment for crop growth and indirectly improving agricultural production efficiency.

[0020] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1-3 This embodiment provides the following technical solution: a seepage-proof farmland ditch structure for crop planting, including a prefabricated ditch component 1. The two ends of the prefabricated ditch component 1 are integrally formed with staggered connectors 2, and when two prefabricated ditch components 1 are spliced, the head forms a zigzag gap at the connection of the connectors 2. Connecting grooves 3 are provided on the upper and lower surfaces of both ends of the prefabricated ditch component 1. A cast-in-place component is cast between the two prefabricated ditch components 1, and the cast-in-place component wraps around the upper part of the connectors 2 and fills the connecting grooves 3. A downwardly recessed mud discharge groove 7 is provided in the middle of the prefabricated ditch component 1, and a detachable flow-blocking component is provided in the middle of the prefabricated ditch component 1.

[0022] In this embodiment, the connectors 2, which are integrally formed and staggered at both ends of the prefabricated ditch component 1, facilitate the formation of a zigzag gap at the connection point of the connectors 2 when the two prefabricated ditch components 1 are spliced ​​together. This allows for the casting of a cast-in-place component at the connection point of the two prefabricated ditch components 1, which wraps around the upper part of the connector 2. This increases the stability of the connection between the two prefabricated ditch components 1 and solves the problem of leakage caused by cracks when concrete is directly applied between the two prefabricated ditch components 1. The cast-in-place component also fills the connection groove 3, which increases the reliability of the connection between the prefabricated ditch component 1 and the cast-in-place component. The middle part of the prefabricated ditch component 1 is recessed to form a sludge discharge groove 7. A detachable flow-blocking component is provided in the middle part of the prefabricated ditch component 1. This allows the flow-blocking component to reduce the area through which water flows in the middle part of the prefabricated ditch component 1. This reduces the flow velocity of water as it flows through the middle part of the prefabricated ditch component 1 due to the reduced area, thus facilitating the flow of silt and reducing the sedimentation of silt in the prefabricated ditch component 1.

[0023] Specifically, the cast-in-place components include a cast-in-place slab 4 located above the connector 2, a cast-in-place bend line 5 located in the gap between the bends, and a cast-in-place column 6 located in the connecting groove 3. The cast-in-place slab 4, the cast-in-place bend line 5, and the cast-in-place column 6 are integrally formed, and the cast-in-place slab 4 and the cast-in-place bend line 5 are fitted together to wrap around the upper part of the connector 2. The connector 2 is an isosceles trapezoidal structure.

[0024] In this embodiment, a cast-in-place component consisting of a cast-in-place slab 4, a cast-in-place folded line 5, and a cast-in-place column 6 is used. The cast-in-place slab 4 is located above the connector 2, the cast-in-place folded line 5 is located within the folded line gap, and the cast-in-place column 6 is located within the connecting groove 3. This facilitates a more reliable connection between the cast-in-place component and the precast ditch component 1 after the cast-in-place component is formed.

[0025] Specifically, the sludge discharge trough 7 has a "V" shaped structure.

[0026] Specifically, the flow obstruction component includes two guide strips 8 integrally formed on the inner surface of the prefabricated ditch component 1, and a water baffle 9 is inserted between the two guide strips 8. There are four water baffles 9, and the four water baffles 9 are isosceles trapezoidal structures.

[0027] In this embodiment, the flow obstruction component composed of guide strip 8 and baffle plate 9 facilitates the adjustment of the water flow area in the middle of the prefabricated ditch component 1 by adjusting the number of baffle plates 9 installed in the guide strip 8, thereby facilitating the adjustment of the water flow velocity.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
