Description

A simple ecological buffer zone interception ditch Technical Field

[0001] This utility model applies to the field of ecological buffer zone construction and provides a simple ecological buffer zone interception ditch. Background Technology

[0002] Interception ditches are placed in farmland irrigation ditches to block the flow of water. They divert water from the ditches into water bodies, promoting drainage in farmland, protecting water quality, slowing down water flow, preventing soil erosion, maintaining the stability of ditches, and promoting sustainable agricultural ecological development.

[0003] Current ecological buffer zone interception ditches are typically constructed using traditional concrete structures, and their construction process includes soil improvement, infrastructure construction, and vegetation planting. Traditional concrete interception ditches, through a hardened ditch body and a corresponding drainage system, achieve water diversion and distribution.

[0004] However, traditional ecological buffer zone interception ditches have several drawbacks in practical applications. Currently, precast concrete interception ditch components, once assembled, do not provide an ecological buffering effect. The transition points between the precast components and the soil are easily eroded by water flow, leading to severe soil loss and accelerating the aging and damage of the ditch. Furthermore, due to their weight, the precast concrete interception ditch components require large lifting equipment for section-by-section installation, making modular construction methods such as disassembly, transportation, and installation impossible. Summary of the Invention

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a simple ecological buffer zone interception ditch, aiming to solve the problems mentioned in the background art. The device includes...

[0006] The embedded part and the top structural component installed on both sides of the top of the embedded part; the embedded part is in the shape of a long groove, and the bottom plate of the embedded part is uniformly provided with a flow-suppressing groove, which makes the top of the bottom plate of the embedded part present a wave-shaped structure, and the top structural component is uniformly provided with several through holes.

[0007] Furthermore, the embedded part includes a base plate and two side plates, with the two side plates set at obtuse angles on both sides of the base plate.

[0008] Furthermore, the side plate and the bottom plate of the embedded part are designed with a 135° obtuse angle.

[0009] Furthermore, both the embedded parts and the top structural parts are precast concrete structural parts, and both the embedded parts and the top structural parts are internally equipped with steel reinforcement skeleton structures.

[0010] Furthermore, the several through holes on the top structural member form a honeycomb pattern.

[0011] Furthermore, prefabricated planting bags can be directly placed inside the through holes.

[0012] Furthermore, the bottom ends of the embedded part are respectively provided with a connecting part and a connecting groove, and the positions and sizes of the connecting part and the connecting groove correspond to each other.

[0013] Furthermore, the connecting part and the connecting groove are respectively provided with insertion holes and fixing heads, and the size and corresponding position of the insertion holes and fixing heads are matched with each other.

[0014] Furthermore, the embedded part has overlapping grooves on both sides, and the top structural member has an overlapping part that matches the overlapping grooves on the side near the edge of the embedded part.

[0015] Therefore, this utility model, by constructing a three-dimensional ecological buffer system and utilizing the combined water-blocking mechanism of the wave-shaped flow-suppressing structure and the plant community within the honeycomb-shaped through-holes, more effectively solves the industry problem of easy erosion in the transition zone at the edge of the ecological buffer zone interception ditch.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0024] Referring to Figures 1-3, the purpose of this utility model is to provide a simple ecological buffer zone interception ditch, including an embedded part 1 and top structural parts 2 installed on both sides of the top of the embedded part 1; the embedded part 1 is a long groove shape, with a bottom plate and two side plates, the two side plates are angled on both sides of the bottom plate, and the two side plates are set at an obtuse angle with the bottom plate. Specifically, both the embedded part 1 and the top structural parts 2 are precast concrete structural components, with a steel reinforcement skeleton structure arranged inside, and are cast into shape using a molding mold.

[0025] The bottom plate of the embedded part 1 is uniformly provided with flow-suppressing grooves 13, which give the top of the bottom plate of the embedded part 1 a wavy structure. The wavy flow-suppressing grooves 13 can reduce the water flow velocity from 0.8m / s to 0.3m / s and extend the hydraulic residence time by 1.5 times. The top structural component 2 is uniformly provided with several through holes 21, specifically, the several through holes 21 form a honeycomb pattern.

[0026] In the modular construction process of this device, the trench is first excavated according to the designed slope (1:1.5), with a bottom width of 0.6m and a depth of 0.8m. Then, straw bundles (arranged horizontally) are laid at the bottom of the trench, and the upper layer is filled with gravel and the original soil from the trench excavation to 1 / 3 of the trench depth. The embedded part 1 is then hoisted and laid using a lifting device, ensuring that the top surface of embedded part 1 is a certain distance from the ground surface, this distance being greater than the thickness of the outer edge of the top structural component 2. After the embedded part 1 is laid, the gaps are filled with soil. Then, the top structural component 2 is hoisted and laid on both sides of the embedded part 1, ensuring that the upper surface of the top structural component 2 is a certain distance from the ground surface. Finally, soil is filled into the several through holes 21 on the top structural component 2. During the filling process, plant seeds are scattered into the through holes 21, and water is sprinkled to stabilize the soil, thus completing the laying of one section of the interception trench. Specifically, the vegetation planted in the through hole 21 can be vetiver grass and willow; prefabricated planting bags containing humus can be placed directly in the through hole 21. The bottom of the prefabricated planting bag has a similar shape to the through hole 21 and can be directly embedded into the honeycomb-shaped through hole 21 to achieve a better installation effect.

[0027] Preferably, the bottom ends of the embedded part 1 are respectively provided with a connecting part 11 and a connecting groove 12. The positions and sizes of the connecting part 11 and the connecting groove 12 correspond to each other. When adjacent embedded parts 1 are connected to each other, the later installed embedded part 1 can be fitted together with the connecting groove 12 on the previous embedded part 1 through its own connecting groove 12, thereby achieving a tighter fit, ensuring that the soil at the joint of the interception ditch is not easily eroded away, and ensuring the stability of the interception ditch in long-term use.

[0028] Preferably, the connecting part 11 and the connecting groove 12 are respectively provided with a socket 111 and a fixing head 121. The size and corresponding position of the socket 111 and the fixing head 121 are matched with each other. When adjacent embedded parts 1 are connected to each other, the fixing head 121 on the later installed embedded part 1 can be inserted into the socket 111, thereby completing a tighter connection. This also ensures a certain degree of tightness between each embedded part 1 even when geological conditions change.

[0029] Preferably, the embedded part 1 has overlapping grooves 10 on both sides, and the top structural part 2 has an overlapping part 20 that matches the overlapping groove 10 on the side near the edge of the embedded part 1. The overlapping part 20 can be embedded in the inside of the overlapping groove 10, that is, it is placed on the overlapping groove 10. The overlapping groove 10 has the function of restricting the displacement of the top structural part 2.

[0030] In practical use, the wave-shaped flow-damping groove 13 on the bottom plate of the embedded part 1 effectively reduces the intensity of water flow turbulence. Its special curved surface structure achieves kinetic energy attenuation by extending the water flow path, providing sufficient conditions for the settling of suspended solids. The side plate of the embedded part 1 is designed with a 135° obtuse angle to the bottom plate, which can fully accommodate a sufficient amount of water flow. In terms of connection and fit, the tenon-and-mortise interlocking structure of the connecting part 11 and the connecting groove 12 forms shear resistance in the longitudinal direction of the groove, which can better maintain the stability of the connection structure of each section. The dovetail-shaped interlocking structure of the overlapping groove 10 and the overlapping part 20 ensures that the top structural component 2 does not slip laterally during installation, making installation easier.

[0031] Meanwhile, in terms of biological anchoring, the prefabricated planting bags embedded in the through holes 21 of the top structural component 2 form a three-dimensional biological anchoring system through the deep root systems of vetiver grass and willow. The root penetration depth can reach the area of ​​the pre-embedded component 1. At the same time, the plant buffer system located above the ground surface can more effectively play the role of soil stabilization.

[0032] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
