Description

Technical Field

[0001] The utility model relates to the technical field of ditch head protection, in particular to a protective device for preventing ditch head erosion and soil loss. Background Art

[0002] There are thousands of gullies on the surface of the Loess Plateau, and there are ditches in them. The high altitude in the gully is considered to be the gully head. If soil erosion is not prevented, the gully will become larger and longer. The enlargement or lengthening of the gully in the direction of the gully head is the upstream erosion. In order to prevent the gully head from advancing and protect the slope from being cut, a protective structure is built at the gully head. However, in actual use, the existing gully head protection device is generally designed with water flow guidance facilities near the gully to reasonably guide the water flow, and flexible buffer materials are installed at the bottom of the gully to reduce the possibility of erosion and loss. This method has a weak ability to weaken the water flow during diversion, resulting in poor gully head protection effect. Utility Model Content

A plurality of I-shaped energy dissipation stones are provided on the main body of the soil erosion protection device to reduce the scouring of the ditch bank by the water flow. An elastic buffer layer is provided on the slope protection to further achieve energy dissipation and keep the water area in the ditch stable.

[0006] Preferably, the cross-section of the main body of the soil and water loss protection device is a trapezoidal structure. The main body of the soil and water loss protection device is made of concrete. A stable protection structure is constructed by using durable concrete materials to resist water erosion and natural weathering.

[0007] Preferably, the inner side of the protective frame is connected to a square guard plate, which is evenly spaced. By adding square guard plates on the side, the side slope can be stabilized, thereby effectively preventing mud and debris from entering the ditch head.

[0008] Preferably, the slope protection is an arc-shaped structure, and a buffer layer is arranged at the upper end of the slope protection. The cross-section of the buffer layer is a wavy line structure. The buffer layer is made of elastic latex material. By setting the elastic buffer layer, the impact of the water flow in the cantilever pipe can be effectively weakened, thereby playing a role in energy dissipation.

[0009] Preferably, the lower end of the main body of the soil and water loss protection device is connected to a sedimentation tank, and the upper end of the main body of the soil and water loss protection device is provided with a filter screen.

There are several protective protrusions, and the protective protrusions are made of elastic rubber material. The surface area of ​​the energy dissipation stone can be increased by the protective protrusions, thereby helping to weaken the potential energy of the water flow.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the device for preventing ditch head erosion and soil erosion protection, by setting a sedimentation pool at the entrance where water flows into the ditch, can reduce the entry of silt and debris into the ditch by using a mesh filter plate, intercept silt, and reduce the degree of erosion, and also by setting a number of I-shaped energy dissipation stones on the main body of the soil erosion protection device, thereby reducing the scouring of the ditch bank by the water flow, and by providing an elastic buffer layer on the slope protection, thereby further achieving energy dissipation, secondary weakening the impact force of the water flow, and keeping the water area in the ditch stable. Compared with traditional protection methods, the device adopts a multi-stage method of slowing down the water flow speed and precipitating suspended particles, which greatly reduces ditch head erosion and soil erosion, protects the ditch head, and thus maintains the stability and health of the ecological environment.

[0018] See also Figure 1-2 The utility model provides a technical solution: a soil and water loss protection device for preventing ditch head erosion, comprising a soil and water loss protection device body 1, a cantilever pipe 2, a first fixed pile 3, a second fixed pile 4, a protection frame 5, and a slope protection 7; the right side of the soil and water loss protection device body 1 is connected to the cantilever pipe 2, the lower end of the soil and water loss protection device body 1 is provided with a first fixed pile 3, the lower end of the soil and water loss protection device body 1 is provided with a second fixed pile 4, the right side of the soil and water loss protection device body 1 is connected to the protection frame 5, and the lower end of the protection frame 5 is connected to the slope protection 7, by arranging a sedimentation pool 9 at the entrance of the water flow into the ditch, using a mesh filter plate 10 to reduce the entry of silt and debris into the ditch, and by arranging a plurality of I-shaped energy dissipation stones 11 on the soil and water loss protection device body 1, the water flow on the ditch is reduced. The scouring of the bank, and by providing an elastic buffer layer 8 on the slope protection 7, further energy dissipation is achieved to keep the water area in the ditch stable. The cross-section of the main body 1 of the soil and water loss protection device is a trapezoidal structure. The main body 1 of the soil and water loss protection device is made of concrete. A stable protective structure is constructed by using durable concrete materials to resist water erosion and natural weathering. A square guard plate 6 is connected to the inner side of the protection frame 5. The square guard plates 6 are evenly spaced. By adding pieces of square guard plates 6 on the side, the side slope can be stabilized, thereby effectively preventing mud and debris from entering the ditch head. The slope protection 7 is an arc structure, and a buffer layer 8 is provided at the upper end of the slope protection 7. The cross-section of the buffer layer 8 is a wavy line structure. The buffer layer 8 is made of elastic latex material. By providing an elastic buffer layer 8, the impact of the water flow in the cantilever pipe 2 can be effectively weakened, thereby playing a role in energy dissipation.

[0019] See also Figure 3-4In this embodiment, the lower end of the main body 1 of the soil and water loss protection device is connected with a sedimentation tank 9, and the upper end of the main body 1 of the soil and water loss protection device is provided with a filter screen plate 10. By arranging the sedimentation tank 9 at the entrance where the water flow enters the groove, and cooperating with the filter screen plate 10 to prevent silt and debris from entering the groove, ditch head erosion and soil and water loss are reduced. The upper end of the main body 1 of the soil and water loss protection device is provided with an energy dissipation stone 11. The energy dissipation stone 11 is an I-shaped structure. The energy dissipation stones 11 are staggered. Most of the potential energy of the water flow can be offset by the energy dissipation stones 11 to reduce the scouring of the ditch bank by the water flow, thereby achieving the purpose of energy dissipation. A protective protrusion 12 is provided on the left side of the energy dissipation stone 11. There are several protective protrusions 12. The protective protrusion 12 is made of elastic rubber material. The surface area of ​​the energy dissipation stone 11 can be increased by the protective protrusion 12, which helps to weaken the potential energy of the water flow.

[0020] When the device for preventing ditch head erosion and soil erosion of the present technical solution is used, water first flows through the filter screen 10 to prevent mud and debris from entering the ditch, so that the debris in the water can fall into the sedimentation pool 9, and then the potential energy of the water flow is weakened by the energy dissipation stone 11. Then, the water flow will fall from the cantilever pipe 2 onto the slope protection 7, and finally further dissipate energy through the elastic buffer layer 8 to avoid scouring the soil, thereby protecting the ditch head.

[0021] Through the above steps, the sedimentation tank 9 is first used to precipitate the silt in the water flow, and then the water flow speed is slowed down through multi-stage energy dissipation, thereby greatly reducing ditch head erosion and soil erosion, protecting soil resources, and thus ensuring the stability of the ditch head.
