Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, specifically a soil and water conservation steep slope fixing device. Background Technology

[0002] Steep slopes, influenced by natural or human factors such as steep gradients, improper land use, destruction of vegetation, and loose soil, allow rainwater to flow down the slope and erode the soil, resulting in the simultaneous loss of both water and soil. Therefore, slope stabilization devices are needed to reinforce steep slopes.

[0003] Chinese utility model patent CN210439310U discloses a slope fixing device for preventing soil erosion, comprising a first reinforcing frame and a second reinforcing frame. The device is characterized by: the first and second reinforcing frames being fixed together by welding; a conical hopper fixed between the first and second reinforcing frames; and a vertical pipe vertically fixed to the lower end of the conical hopper. The side wall of the vertical pipe has multiple evenly arranged through holes. This utility model patent, through the arrangement of the first and second reinforcing frames, can reinforce the slope, effectively mitigating the large-area, long-distance erosion of the slope by rainwater, while also facilitating the collection of backflowing rainwater, allowing excess rainwater to flow directly into deeper layers along the vertical pipe, thereby conserving soil and water. However, when the slope area is large, a large number of vertical pipes are required, necessitating the cleaning of the soil clogging the inside of each vertical pipe, increasing the workload of vertical pipe cleaning. Furthermore, the cleaned soil can accumulate on the slope, easily being washed away by rainwater if not cleaned in time, reducing the practicality of this device.

[0004] Therefore, this utility model provides a device for fixing steep slopes in soil and water conservation. Utility Model Content

It can also remove and reposition the soil inside the silt collection trough, preventing soil accumulation and loss with rainwater, thus reducing the workload of soil cleaning and improving the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slope fixing device for soil erosion control, comprising a slope protection slab and a silt collection mechanism. The silt collection mechanism includes a cement trough and a silt collection trough. The cement trough is fixedly installed at the bottom of the slope protection slab by a second anchor rod.

A rotating rod 7 is movably installed inside the top of the cement trough 4 through a torsion spring shaft. A movable baffle 8 is fixedly installed at one end of the rotating rod 7. One end of the movable baffle 8 overlaps and is installed at the connection between the slope protection plate 1 and the cement trough 4. A first filter screen 16 is fixedly installed inside the movable baffle 8. A baffle strip 17 is fixedly installed at the top of the movable baffle 8. The silt collection trough 5 is installed inside the cement trough 4. A drainage pipe 6 is fixedly connected to one side of the bottom end of the cement trough 4. A second filter screen 18 is fixedly installed inside one end of the silt collection trough 5. The slope protection plate 1 and the cement trough 4 are easily fixed by the second anchor rod 3, so that the water and soil washed on the slope protection plate 1 can enter the cement trough 4. The silt collection trough 5 can be used to filter and collect the soil, preventing the soil from being washed away by rainwater. The silt collection trough 5 can be removed and the silt inside can be treated uniformly by rotating and adjusting the movable baffle 8. The first filter screen 16 can filter out debris such as leaves in the water and soil, so as to prevent them from affecting the subsequent collection of soil.

[0024] In this embodiment, the top and bottom of the slope protection plate 1 are respectively provided with a horizontal end and a vertical end. Symmetrical through holes 15 are provided inside both the horizontal and vertical ends. A first anchor rod 2 is installed inside the top through hole 15. Waterproof slurry is applied between the top of the first anchor rod 2 and the slope protection plate 1. An installation hole is provided inside the cement trough 4 corresponding to the position of the through hole 15. A second anchor rod 3 is installed inside the bottom through hole 15 and the installation hole. A silt collection trough 5 is located on one side of the installation hole and the second anchor rod 3. The first anchor rod 2 can fix the top of the slope protection plate 1 to the top of the steep slope. The waterproof slurry prevents the first anchor rod 2 from being corroded by rainwater, thereby improving its service life. After the silt collection trough 5 is installed inside the cement trough 4, it can limit the position of the second anchor rod 3, thereby improving the stability of the second anchor rod 3.

[0025] In this embodiment, an extension plate is fixedly installed on one side of the top of the sludge collection trough 5, corresponding to the top of the second filter screen 18. One end of the extension plate is in close contact with the inner wall of the cement trough 4. A through groove 19 is opened inside the extension plate. An inclined surface is provided at the top of the sludge collection trough 5, and the inclined surface is in close contact with the bottom of the movable baffle 8. The sludge collection trough 5 is located below the first filter screen 16. The top end of one end of the movable baffle 8 is in close contact with the slope protection plate 1. Limiting mechanisms are provided on the front and rear sides of the vertical end of the slope protection plate 1. The limiting mechanism includes a limiting slide groove 13 and a stop block 14. The limiting slide groove 13 is symmetrically opened on the front and rear sides of the upper surface of the slope protection plate 1. One end of the stop block 14 is slidably installed inside the limiting slide groove 13. The bottom end of the stop block 14 is located at... The top of the movable baffle 8 is in contact with its upper surface. The extension plate can limit the sludge collection tank 5, thereby preventing the sludge collection tank 5 from moving laterally inside the cement tank 4. At the same time, it can ensure that there is a certain space between the sludge collection tank 5 and the cement tank 4 so that rainwater can be discharged through the drain pipe 6. It is convenient to collect soil through the sludge collection tank 5 and prevent soil from being lost with rainwater. The cooperation between the through groove 19 and the extension plate makes it easy to remove the sludge collection tank 5 from the inside of the cement tank 4, which is convenient for the unified treatment of the soil inside the sludge collection tank 5. The baffle 14 can contact the top of the movable baffle 8 under its own weight and limit it. The cooperation between the baffle 14, the torsion spring shaft, and the rotating rod 7 can improve the stability of the movable baffle 8 and facilitate subsequent water and soil filtration.

[0026] In this embodiment, the middle section of the slope protection board 1 has a hollowed-out groove. The straight end of the slope protection board 1 and the front and rear ends of the middle section are respectively provided with a first splicing groove 9 and a first splicing plate 10. The front and rear ends of the cement trough 4 are respectively provided with a second splicing groove 11 and a second splicing plate 12. The hollowed-out groove can expose the steep slope, which is convenient for planting plants to prevent soil erosion on the steep slope and to reinforce the steep slope. The first splicing groove 9 and the first splicing plate 10 are connected to facilitate splicing the slope protection board 1 along the steep slope. The second splicing groove 11 and the second splicing plate 12 are connected to facilitate splicing the cement trough 4, which is convenient for subsequent filtration and collection of soil and prevents soil erosion.

[0027] When using this soil and water conservation steep slope fixing device, a trench for installing the cement trough 4 is excavated at the bottom of the steep slope, and deep holes are drilled at the top of the steep slope and inside the inner wall of the trench. The slope protection plate 1 is installed on the surface of the steep slope, and the first anchor rod 2 is fixedly installed in the through hole 15 inside the straight end of the slope protection plate 1 and in the deep hole. The cement trough 4 is installed inside the trench, and the second anchor rod 3 is fixedly installed in the installation hole and the through hole 15 inside the vertical end of the slope protection plate 1, which facilitates the fixing of the device on the steep slope. The cement trough 4 is a precast concrete product, and other components are spliced ​​and installed along the front and rear sides of the slope protection plate 1. The slope protection panels 1 are fixed together by the insertion of the first splicing groove 9 and the first splicing plate 10. Other cement troughs 4 are installed in the corresponding trenches on the front and rear sides of the cement trough 4, so that the cement troughs 4 are spliced ​​and fixed together by the second splicing groove 11 and the second splicing plate 12. After the slope protection panels 1 and the cement troughs 4 are spliced ​​together, waterproof slurry is applied to the joints. The top of the first anchor rod 2 and the surface of the slope protection panel 1 are also coated with waterproof slurry to prevent water and soil from being lost through the joints. The movable baffle 8 and the rotating rod 7 are rotated upward to open the cement trough 4, and the silt is collected through the extension plate. The trough 5 is installed inside the cement trough 4. Reversing the rotation of the movable baffle 8 and the rotating rod 7 causes one end of the movable baffle 8 to overlap the slope protection plate 1 and contact the top of the silt collection trough 5. The baffle block 14 is a cement block; its own weight and the torque of the torsion spring shaft limit the top of the movable baffle 8, thus improving its stability. Water and soil washed down from the slope protection plate 1 are blocked by the movable baffle 8 and the baffle strip 17, and after being filtered by the first filter screen 16, enter the silt collection trough 5. Leaves and other debris in the water and soil are blocked at the top of the movable baffle 8 and pass through the second filter screen 18. The filter retains the soil in the silt collection trough 5, facilitating soil collection through the trough 5, while rainwater is discharged through the drainage pipe 6, helping to maintain the soil on the steep slope and prevent soil erosion. By adjusting the rotation of the movable baffle 8 and the rotating rod 7, the silt collection trough 5 can be easily removed from the cement trough 4 through the extension plate and the through groove 19, thus facilitating the unified restoration of the soil in the silt collection trough 5, reducing the workload of soil cleaning, preventing the cleaned soil from being washed away by rainwater, and improving the practicality of the device. This fixing device can also reinforce the soil on the steep slope and prevent soil erosion.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
