Abstract
Description
Technical Field
[0001] This utility model relates to a steep slope protection structure based on a honeycomb grid and a double-layer reinforced mesh, belonging to the technical field of slope protection structure. Background Technology
[0002] Currently, when using honeycomb mesh for ecological protection of steep slopes, the mesh cells are typically filled using hydroseeding. However, existing honeycomb mesh cells have large spaces, making it easy for the filler material at the bottom of the cells to accumulate and be squeezed out during hydroseeding, while filling the top of the cells is difficult. Furthermore, the filler surface is prone to cracking during the dry season, and during the rainy season, the weak initial root systems of the grasses and shrubs cannot effectively reinforce the filler material, nor can they intertwine and wrap around the plants within the mesh openings to enhance their adhesion, thus affecting the overall slope protection capacity. To address the shortcomings of existing technologies that rely solely on honeycomb mesh, the inventors have designed a steep slope protection structure with reinforcing mesh in both the upper and lower layers of the honeycomb mesh. Utility Model Content
[0003] The purpose of this invention is to provide a steep slope protection structure based on honeycomb mesh and double-layer reinforced mesh, overcoming the defects and deficiencies in the existing technology. This allows for better filling and constraint of the cell filler when honeycomb mesh is applied to steep slopes. After the grass and shrubs grow, their roots intertwine with the reinforced mesh and honeycomb mesh to form a whole. By adding a double-layer reinforced mesh, the bonding force between the filler, honeycomb mesh, reinforced mesh and plant roots is maximized, thereby improving the overall erosion resistance and stability of the slope.
[0004] This utility model is achieved through the following technical solutions, including a slope surface, a slope toe and a slope shoulder, as well as an upper reinforcing mesh, a honeycomb mesh, a base filler, a lower reinforcing mesh and a planting filler layer; The mesh size of the lower layer of reinforcing mesh is 1 to 10 cm; the lower layer of reinforcing mesh is tensioned and covered on the slope surface and fixed to the slope surface with anchors; The honeycomb mesh is laid on top of the lower reinforcing mesh and fixed with anchors; The base filler contains planting soil, binder, water-retaining agent, plant fiber, and fertilizer, which is mixed and sprayed into the honeycomb grid by a hydroseeding machine; The mesh size of the upper reinforcing mesh is 5 to 15 cm; the upper reinforcing mesh is stretched and laid above the honeycomb mesh and tied to the through holes of the honeycomb mesh with rope or cable ties. The planting filler layer contains planting soil, binder, plant fiber, fertilizer, and seeds, which are mixed by a hydroseeder and sprayed onto the upper reinforced mesh to a thickness of 2 to 5 cm.
[0005] The upper and lower reinforcing mesh ropes are made of multiple twisted fibers, with a rough surface, grooves, and knots.
[0006] The upper and lower reinforcing meshes are made of PE fiber ropes woven into a mesh structure of uniform specifications, which, after tensioning, form a quadrilateral or hexagonal shape.
[0007] A water-blocking embankment or intercepting ditch shall be installed at the aforementioned slope shoulder location; The water-retaining embankment is equipped with one or two layers of honeycomb mesh depending on the water catchment at the top of the slope. After anchoring, the original soil in the cells is backfilled and compacted.
[0008] The beneficial effects of this utility model are as follows: [1], on the basis of the original honeycomb mesh protection, a double-layer reinforced mesh is added to enhance the stability of the cell filler; [2], the filler, plants, honeycomb mesh and double-layer reinforced mesh are combined to improve the integrity and protective ability of the protective layer.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model; moreover, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

In the various figures, the same elements are indicated by similar reference numerals. For clarity, the various parts in the figures are not drawn to scale.
[0013] This utility model includes a slope 10, a slope shoulder 20 and a slope foot 30, and also includes an upper reinforcing mesh 1, a honeycomb mesh 2, a lower reinforcing mesh 3, a base filler 4, and a planting filler layer 5. The lower layer of reinforcing mesh 3 is tensioned and covered on the slope surface 10. After being fixed with anchor nails at the slope shoulder 20, the lower layer of reinforcing mesh 3 is stretched to the slope foot 30 and fixed, ensuring that the mesh of the lower layer of reinforcing mesh 3 is straight and quadrilateral or hexagonal. The slope surface of the lower layer of reinforcing mesh 3 is fixed with U-shaped nails and adhered to the slope surface 10. The mesh diameter of the lower layer of reinforcing mesh 3 is 1 to 10 cm. The lower layer of reinforcing mesh 3 can be spliced or overlapped, and the overlap distance is ≥2 cm. The honeycomb mesh 2 is laid on top of the lower reinforcing mesh 3 and fixed with anchors. The cells of the honeycomb mesh 2 are filled with matrix filler 4. The base filler 4 contains planting soil, binder, water-retaining agent, plant fiber, and fertilizer, which is mixed and sprayed into the honeycomb grid 2 by a hydroseeding machine; The upper reinforcing mesh 1 is stretched and laid on top of the honeycomb mesh 2. After being fixed with anchor nails at the slope shoulder 20 of the upper reinforcing mesh 1, it is stretched to the slope foot 30 and fixed to ensure that the mesh of the upper reinforcing mesh 1 is straight and in the shape of a quadrilateral or hexagon. It is then tied to the through holes of the honeycomb mesh with rope or cable ties. The mesh diameter of the upper reinforcing mesh 1 is 5 to 15 cm. The upper reinforcing mesh 1 can be spliced or overlapped, and the overlap distance is ≥5 cm. The planting filler layer 5 contains planting soil, binder, plant fiber, fertilizer, and seeds, which are mixed by a hydroseeder and sprayed onto the upper reinforcing mesh 1 to a thickness of 2 to 5 cm.
[0014] The upper and lower reinforcing meshes 1 and 3 are made of multiple twisted fibers, with a rough surface, grooves, and knots.
[0015] The upper and lower reinforcing meshes 1 and 3 are made of PE fiber ropes woven into a mesh structure of the same specifications, which are quadrilateral or hexagonal after tensioning.
[0016] A water-blocking embankment 6 or a diversion ditch 7 shall be provided at the slope shoulder 20 location; The water-retaining embankment 6 is equipped with one or two layers of honeycomb mesh depending on the water catchment at the top of the slope. After anchoring, the original soil in the cells is backfilled and compacted.
[0017] The embodiments of this utility model are as follows: Step 1, Repairing Steep Slopes: For steep slopes with water damage, use ecological bags filled with soil or honeycomb mesh backfill to repair and level the slope by compacting the soil layer by layer. Repair and reinforce the drainage ditch at the slope shoulder 20. Make a drainage channel at the lowest point of the water collection point at the slope shoulder 20. Ensure that the water collected at the top of the slope is intercepted, blocked, and drained into the ditch at the bottom of the slope in a timely manner. Ensure that the repaired slope is free of large pits, boulders, garbage, weeds, and shrubs. When there are trees or large shrubs that cannot be moved, the lower layer of reinforcing mesh 3, honeycomb mesh 2, and upper layer of reinforcing mesh 1 should all have reserved connection positions at this location. That is, leave a reserved position at the corresponding slope shoulder 20 of the immovable plants without connecting or binding them. When the upper and lower layers of reinforcing mesh 1 and 3 and honeycomb mesh 2 are laid, they will be connected layer by layer at this location. Cut and reserve growth space according to the growth trend of the plants. Step 2, Hang the lower layer of reinforcing mesh 3: Calculate the amount of lower layer reinforcing mesh 3 needed based on the length and width of the slope surface 10 to be protected. The reinforcing mesh is tied together with the same material wire on the left and right sides and top and bottom, with an overlap of ≥2cm. After fixing the slope shoulder 20 with anchor nails, stretch it to the slope foot 30 and fix it, ensuring that the mesh of the lower layer reinforcing mesh 3 is straight and in the shape of a quadrilateral or hexagon. Use U-shaped nails to fix it evenly in the middle of the slope so that the lower layer reinforcing mesh 3 fits the slope surface. Step 3, Laying the honeycomb mesh 2: Calculate the usable area of the honeycomb mesh 2 based on the length and width of the lower reinforcing mesh 3, i.e., the number of horizontal and vertical groups of the honeycomb mesh 2, and connect them according to the shape of the slope; measure and draw lines from the starting edge of the slope and the anchoring points of the slope shoulder 20, and pre-anchor anchors or high-strength fiber piles according to the size of the cells. Anchor one pile for each cell at the starting edge, and anchor one pile for each cell or one pile every other cell at the slope shoulder 20 until the design length; hang the connected honeycomb mesh 2 cells from the starting edge onto the anchors or high-strength fiber piles one by one according to the pre-anchoring positions. On the support piles, the honeycomb mesh 2 near the far side of the slope shoulder 20 is temporarily fixed to the slope toe 30. During the support process, ensure that the lower reinforcing mesh 3 is not hooked or dragged. Alternatively, bamboo poles or cylinders can be evenly placed on the lower reinforcing mesh 3 to isolate the two. After the honeycomb mesh 2 reaches the slope toe 30, it is removed. Finally, ensure that the cell edges of the honeycomb mesh 2 are anchored to the slope toe 30 in a straight line in the horizontal, vertical, and diagonal directions. The honeycomb mesh 2 on the slope surface is anchored with anchors according to the principle of denser at the top and sparser at the bottom, using a horizontal one and a vertical two method, ensuring that the bottom edge of the honeycomb mesh 2 and the lower reinforcing mesh 3 are in contact with the slope surface 10. The base layer filler 4 is mixed by a hydroseeding machine and sprayed into the honeycomb mesh 2. Step 5, Hang the upper reinforcing mesh 1: Cut the upper reinforcing mesh 1 according to the length and width of the honeycomb mesh 2 protection. Each group of reinforcing mesh is connected by binding the left and right sides and the top and bottom with the same material of mesh wire, with an overlap of ≥5cm. After fixing the slope shoulder 20 with anchor nails, stretch it to the slope foot 30 and fix it, ensuring that the mesh of the upper reinforcing mesh 1 is straight and in the shape of a quadrilateral or hexagon, and tie it to the through hole of the honeycomb mesh 2 with rope or cable tie. Step 4, Filling with substrate: Prepare substrate filler suitable for local plant growth according to the conditions of different regions, such as well-fermented odorless animal manure, organic fertilizer, biological bacteria, mixed grass and wood fibers, water-retaining agent, etc., and mix them thoroughly with planting soil and water. Spray the mixture into the grid chamber as the bottom layer for plant growth until the grid chamber is full. Mix organic fertilizer, rice husk, biological bacteria, mixed grass and wood fibers, binder, grass and shrub seeds, planting soil and water thoroughly and spray them onto the reinforcing mesh 1 to form the planting filler layer 5. Ensure that the upper reinforcing mesh 1 is evenly covered with a thickness of 2 to 5 cm. Step 6, Early Plant Growth Protection: After spraying the surface layer, cover it with a layer of straw mat, straw blanket, or non-woven fabric to protect the stability of the grass shrub seeds during the early growth stage. This serves two purposes: firstly, to prevent wind and rain from causing low seed survival rates; and secondly, to reduce evaporation from the slope and provide sufficient moisture for the seeds in the early stages. Depending on local rainfall, if there is no rainfall for seven consecutive days within the first 30 days, artificial watering is required for maintenance.
