Abstract
Description
Technical Field
[0001] This utility model belongs to the field of geotechnical engineering protection technology, and specifically relates to an ecological protection structure for gravel slopes based on plant bags and vine gabions. Background Technology
[0002] Traditional gravel slope protection often employs rubble retaining walls, shotcrete mesh, concrete grids, or pure gabion structures, which suffer from poor ecological benefits, uncoordinated landscape, and high maintenance costs. Ecological slope protection technologies such as bio-bags, slope protection bags, and vegetation bags simply involve laying and fixing protective bags in gravel slopes. When the rainy season arrives, these bags are prone to failure due to soil erosion. All of these problems affect the stability of the slope and soil. Utility Model Content
[0003] To address the existing technical problems, this utility model proposes an ecological protection structure for gravel slopes based on plant bags and vine gabions, which can solve the current problem of poor slope water and soil stability.
[0004] The purpose of this utility model and the technical problem it solves are achieved by the following technical solution. According to this utility model, an ecological protection structure for a gravel slope based on plant bags and gabions includes a support plate, a plant bag layer, a gabion layer, and a water-retaining plate on the slope shoulder, all placed on the slope surface. The plant bag layer is located between the water-retaining plate and the support plate, and is composed of several geotextile bags stacked along the slope surface. Adjacent geotextile bags are detachably connected, and geotextile bags conforming to the slope are fixedly connected to the slope surface. The gabion layer is located between the support plate and the slope toe, and is composed of several gabions stacked in a stepped shape. The outer walls of contacting gabions are detachably connected, and gabions conforming to the slope are fixedly connected to the slope. Vines are pre-embedded on the outside of the gabions. A first gravel layer, a planting layer, and a second gravel layer are sequentially arranged within the gabions furthest from the slope, with the first gravel layer located close to the slope.
[0005] Furthermore, the water-retaining plate is anchored to the slope via the first anchor rod.
[0006] Furthermore, the geotextile bags that fit the slope are anchored to the slope via a second anchor rod.
[0007] Furthermore, the support plate is provided with several water-permeable holes, and the support plate is anchored to the slope by a third anchor rod.
[0008] Furthermore, several foundation trenches are provided on the slope, and gabions that fit the slope are placed in the foundation trenches, with a concrete cushion layer between the gabions and the slope.
[0009] Furthermore, any outer wall surface of the gabion that fits the slope is anchored to the slope via a fourth anchor bolt.
[0010] Furthermore, the outer walls of the gabions that are in contact are connected by U-shaped anchors.
[0011] Furthermore, the planting layer is separated from the first and second gravel layers by grids on both sides.
[0012] Furthermore, a stop block for limiting the gabion is installed at the toe of the slope.
[0013] Furthermore, the outermost layer of plant bags is covered with a fixing net.
[0014] In summary, this utility model has the following advantages:
[0015] 1. Multiple geotextile bags are set up to form a plant bag layer, which is fixed to the slope, strengthening the adhesion between the plant bag layer and the slope. At the same time, a support plate is set up to support the plant bag layer and a water retainer to divert water and soil from the top, reducing the scouring force of rainwater and the amount of soil loss, avoiding the failure of the plant bag layer due to soil loss, thereby stabilizing the slope structure.
[0016] 2. The gabions can be detached and connected, which facilitates construction and allows for the individual removal of a gabion for easy maintenance.
[0017] 3. Plant seedlings of vines are pre-buried on the outside of the gabion. The roots of the vines can penetrate the gabion to enhance the overall tensile strength. The interior is divided into planting layers, which can reduce the pressure of the stones on the planted plants, facilitate plant growth, further improve the strength of the gabion, and at the same time improve ecological benefits and maintain the harmony of the slope landscape.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, preferred embodiments are given below, and detailed descriptions are provided in conjunction with the accompanying drawings.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.
[0023] Please see Figure 1 An ecological protection structure for gravel slope based on plant bags and gabions includes a support plate 8, a plant bag layer 5, a gabion layer 10, and a water-retaining plate 2 on the shoulder of the slope 1, which can divert rainwater when the rainfall is large during the rainy season to prevent rainwater from directly washing away the plant bag layer 5. At the same time, diversion holes can be opened on the water-retaining plate 2 to divert water appropriately to supply the water required by the plant bag layer 5. The water-retaining plate 2 is anchored to the slope 1 by the first anchor rod 4.
[0024] Plant bag layer 5 is placed between water retaining plate 2 and support plate 8. That is, plant bag layer 5 is laid on the slope from the slope shoulder to the support plate 8. After the plant bag layer 5 is laid, the slope of the layer edge is less than 45° and the layer height is less than 6m. The outermost plant bag layer 5 is covered with a fixing net 7, which can reduce the amount of water and soil erosion on the surface of the plant bag layer 5 and stabilize the plant bag layer 5.
[0025] The plant bag layer 5 is composed of several geotextile bags stacked along the slope surface of slope 1. The geotextile bags are laid in layers (at least three layers) from the support plate 8 upwards. The bags are filled with planting soil and organic fertilizer. After each layer is compacted, drought-resistant grass and shrub mixed seeds are sown to make the internal structure of the geotextile bags compact and control shallow erosion of slope 1. At the same time, adjacent geotextile bags can be connected by anchor nails (such as U-shaped anchor nails). The geotextile bags that fit into slope 1 are anchored to the slope surface of slope 1 by the second anchor rod 6, which can stabilize the position of the plant bag layer 5, reduce slippage, and ensure soil and water stability.
[0026] The support plate 8 is located at the waist of the slope 1 (i.e., the middle of the slope). The support plate 8 has several water-permeable holes and is anchored to the slope 1 by the third anchor rod 9. The support plate 8 can provide support for the plant bag layer 5, preventing the plant bag layer 5 from sliding down under the action of gravity and rainwater impact after long-term use, and stabilizing its position.
[0027] Please see Figure 1 , Figure 2 Several foundation trenches are excavated on the slope surface of slope 1. Gabions that fit into slope 1 are placed in the foundation trenches, and the gabions are connected to slope 1 by a concrete cushion layer 11. The gabion layer 10 is placed between the support plate 8 and the toe of slope 1. The gabion layer 10 is composed of several gabions stacked in a staggered, stepped shape. The outer walls of the gabions that are in contact are connected by U-shaped anchors 18. The modular design facilitates construction and subsequent maintenance. Any outer wall of the gabion that fits into slope 1 is anchored to slope 1 by a fourth anchor rod 12. At the same time, a stop block 13 for limiting the gabion is provided on the toe of slope 1 to further stabilize the gabion layer 10, thereby resisting the internal shear force of slope 1.
[0028] Seedlings of climbing plants (such as ivy and Virginia creeper) are pre-buried on the outside of the gabions. Several gabions furthest from slope 1 contain a first gravel layer 14, a planting layer 15, and a second gravel layer 17, arranged sequentially. The first gravel layer 14 is positioned close to slope 1, meaning the planting layer 15 is located in the outermost gabion. The planting layer 15 is positioned on the side furthest from the slope 1. The two sides of the planting layer 15 are separated from the first gravel layer 14 and the second gravel layer 17 by gratings 16, reducing the pressure of the gravel on the internal plants, promoting plant growth, providing ecological benefits, and improving the overall ecological balance within the gabions. The strength and tightness of the connection are ensured. The size of the gravel particles filled in the first gravel layer 14 is not limited. Correspondingly, the mesh size of the grid 16 between the first gravel layer 14 and the planting layer 15 is smaller. The size of the gravel particles filled in the second gravel layer 17 is larger. Correspondingly, the size of the grid 16 between the second gravel layer 17 and the planting layer 15 is larger. At the same time, during filling, the internal stones are properly placed and fixed to make them have as many and larger gaps as possible. When the plants inside the planting layer 15 grow, they can pass through the above gaps, so that the surface of the gabion is covered with more plants, which improves the landscape harmony.
[0029] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
