Description

Technical Field

[0001] This invention relates to the field of slope stabilization and planting technology, and in particular to an integrated slope stabilization and planting system with a gradient material-bowl-shaped grid structure. Background Technology

[0002] In slope engineering, reinforcement and ecological restoration are often disconnected. Shotcrete and anchor support, as a typical geotechnical engineering reinforcement technology, is well-established in engineering applications. Through the synergistic effect of shotcrete and anchor systems, a composite support structure with a three-dimensional constraint effect is formed. It is characterized by flexibility, speed, and economy, and has been widely used in slope protection projects.

[0003] Currently, the main development direction of shotcrete and anchor support technology is to improve its reinforcement performance by refining materials and processes, with extensive research conducted, particularly on durability in harsh environments. Although the reinforcement performance has been significantly improved, the deepening of ecological civilization construction has exposed the problem of insufficient ecological compatibility of traditional shotcrete and anchor support technology. Therefore, on the basis of shotcrete and anchor support, it is necessary to first drill vegetation holes on the slope to guide plant root growth, and add auxiliary engineering measures such as grid cells, vegetation mats, and ecological bags, which significantly increases construction costs. At the same time, since the concrete layer and the vegetation layer are still largely separated, the water and fertilizer supply is discontinuous, reducing the long-term effectiveness of greening.

[0004] Furthermore, while existing three-dimensional geocells can confine soil, their homogeneous structure cannot meet the varying mechanical strength and ecological function requirements of slopes from top to bottom. The ordinary topsoil filling the cells fails to create a functional gradient, leading to insufficient base layer strength or poor surface water retention. Simultaneously, traditional geocells have limited capacity to manage rainwater runoff on slopes, either allowing it to infiltrate and cause soil erosion or rapidly draining it away, resulting in water waste. They cannot achieve intelligent interception, distribution, and efficient utilization of rainwater. The traditional step-by-step approach of "reinforcement first, then revegetation" suffers from prominent problems such as low vegetation survival rates, high carbon emissions, and high life-cycle maintenance costs. Existing technologies struggle to achieve multi-objective synergy in slope stability, ecological adaptability, and low-carbon economics, resulting in slope ecological restoration projects facing the dual dilemma of ecological red line constraints and insufficient technology supply. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated slope stabilization and planting system based on a gradient material and a bowl-shaped cell structure. By setting up A-type and B-type cells, focusing on mechanical reinforcement and ecological vegetation functions respectively, and combining them with a bowl-shaped bottom structure, a gradient stabilization and planting synergistic system is formed. This system ensures the overall stability of the slope while achieving guided root growth, efficient water and fertilizer utilization, and long-term ecological restoration.

[0006] To achieve the above objectives, the present invention provides a slope stabilization-planting integrated system with gradient material-bowl-shaped cell structure, comprising cells set on the slope, including type A cells and type B cells, both of which have a bowl-shaped structure in the longitudinal section of their bottoms, and a siphon system is provided between type A cells and type B cells along the y-direction of the slope, wherein gradient material is provided in both type A cells and type B cells.

[0007] Preferably, the A-type cells and B-type cells are assembled and fixed together by connecting frames and are distributed in a checkerboard pattern on the slope, with four A-type cells surrounding the outside of one B-type cell; The bowl-shaped structure of the cell is embedded below the slope, while the square structure of the cell is located on the slope.

[0008] Preferably, the connecting frame is anchored to the slope, and bolts are provided on the outer walls of the square structures of the A-type and B-type cells. The connecting frame is connected to and assembled with the A-type and B-type cells by bolts and nuts.

[0009] Preferably, a water interception ditch is provided at the top of the slope in a horizontal direction to intercept and collect surface runoff, preventing rainwater from directly eroding the slope and causing soil erosion; a water storage tank is also provided at the top of the slope, and the water interception ditch is connected to the water storage tank to store the intercepted rainwater; a water conveyance trough is provided on the slope, and the water conveyance trough is connected to the water storage tank to transport the rainwater in the water interception ditch and the water storage tank to the next gradient cell; a drainage ditch is provided at the bottom of the slope, and the drainage ditch is connected to the water conveyance end of the bottommost cell; Three rows of cubicles are arranged between adjacent water conveyance channels on the slope. Overflow holes are provided on the side walls of the water conveyance channels, facing the cubicles. Water resources output from the overflow holes flow into the cubicles from the top.

[0010] Preferably, the gradient material includes a water-locking and fertilizer-retaining layer, a nutrient life layer, and a reinforced base layer. The B-type cell is provided with the water-locking and fertilizer-retaining layer, the nutrient life layer, and the reinforced base layer from top to bottom, while the A-type cell is only provided with a reinforced base layer. Type B cells are suitable for seeds of plants with well-developed root systems. As the plants grow and develop, the root network will interlock and tightly integrate with the porous matrix, thereby forming a vegetation-reinforced base synergistic enhancement system, which improves the anchoring efficiency and long-term stability of the overall structure. Type A cells also contain seeds, and the selection of plants is unrestricted.

[0011] Preferably, the water-locking and fertilizer-retaining layer is composed of a water-retaining agent, plant fiber, and plant seeds, which can absorb rainwater, reduce rainwater evaporation, and provide a microenvironment for seed germination; the nutrient life layer is composed of soil, organic matter, slow-release fertilizer, and soil conditioner, which provides the necessary nutrients and root space for long-term plant growth.

[0012] Preferably, the reinforced base layer is composed of a porous material formed by the solidification of cement, cold-bonded granulated soil particles and soil conditioning agent. The reinforced base layer has a porous structure, which can efficiently guide the infiltration water and effectively filter out suspended particles and some impurities in the water through physical interception and adsorption, thereby continuously delivering water with high infiltration efficiency and low turbidity to the water collection basin and downhill pipeline.

[0013] Preferably, the reinforced base layer has vertically pre-placed guide channels made of biodegradable material to provide overall anchoring force.

[0014] Preferably, the siphon system includes a water collection basin and a siphon pipe. The bottom of the A-type cell is connected to the water collection basin, the upper end of the siphon pipe extends into the water collection basin from the side wall of the water collection basin, the siphon pipe is also connected to the bottom of the bowl-shaped structure of the B-type cell, and the lower end of the siphon pipe is connected to the water collection basin of the A-type cell of the next gradient. The topmost cell in each of the three rows is also connected laterally by pipes to supply water to the cells in the middle rows.

[0015] A gradient material-bowl-shaped lattice structure integrated slope stabilization and planting system, when used, includes the following steps: Step 1: Treat the slope surface; Step 2: Prefabricate the cells in the processing plant in advance, fill the A-type cells with the reinforced base layer, and fill the B-type cells with the water-locking and fertilizer-retaining layer, the nutrient life layer and the reinforced base layer gradient material from top to bottom; Step 3: Type A cells and Type B cells are assembled and interlocked on the slope using connecting frames, so that Type A cells and Type B cells are distributed in a checkerboard pattern on the slope, with every four Type A cells surrounding one Type B cell. Step four: Then, a siphon system is connected between the A-type and B-type cells along the slope gradient, so that the water from the upper gradient can communicate with the water resources of the lower gradient. Step 5: Finally, spray water on the surfaces of the assembled Type A and Type B cells.

[0016] The advantages and positive effects of the gradient material-bowl-shaped grid structure slope stabilization-planting integrated system described in this invention are as follows: (1) By setting up type A and type B cells, focusing on mechanical reinforcement and ecological vegetation functions respectively, and combined with the bowl-shaped bottom structure, a gradient fixation-planting synergistic system is formed. This system ensures the overall stability of the slope while realizing the guided growth of plant roots, efficient use of water and fertilizer, and long-term ecological restoration.

[0017] (2) The B-type grid is equipped with a water-locking and fertilizer-retaining layer, a nutrient-life layer and a reinforced base layer, forming a functional gradient from top to bottom: the surface layer retains water to promote germination, the middle layer supplies fertilizer to promote growth, and the base layer anchors to allow root penetration. The A-type grid focuses on reinforcement and anchoring, and is arranged alternately with the B-type grid, forming a complementary mechanical and ecological function on the slope, which improves the overall performance and adaptability of the system.

[0018] (3) A rainwater management network integrating collection, storage, transportation, and drainage is formed by intercepting ditches at the top of the slope, water storage tanks, water conveyance channels, and drainage ditches at the bottom of the slope, and a siphon system is combined to achieve gradient mutual assistance of water resources between the cells. The bowl-shaped cells and the siphon pipes work together to effectively collect, store, and distribute rainwater, which not only prevents soil erosion but also provides continuous water support for plant growth, significantly improving water resource utilization efficiency and vegetation survival rate.

[0019] (4) Pre-installed biodegradable root-guiding channels in the reinforced base layer guide plant roots to penetrate downwards, gradually forming a biological anchoring effect and enhancing the deep stability of the slope. The porous structure of the reinforced base layer provides sufficient anchoring force without affecting root development, thus achieving an organic integration of the engineering structure and the natural ecology.
