Description

Technical Field

[0001] The invention relates to the technical field of ecological slope protection and soil and water conservation, and in particular to a reservoir microbial nutrient supply type environmental protection slope system. Background Art

[0002] In the reservoir area of ​​dams and reservoirs, due to seasonal fluctuations in water levels, slopes are extremely susceptible to erosion and landslides, especially in the drawdown zone where the water level changes rapidly. The drawdown zone refers to the area in a river, lake or reservoir that is repeatedly flooded and exposed due to seasonal regulation or natural water level changes. The slopes in this special area are subject to multiple effects of water scouring, soaking and alternating dry and wet conditions, which causes the soil to gradually loosen and the slope stability to decrease, which in turn causes large-scale soil erosion and landslides, seriously threatening the structural safety and ecological environment of the reservoir area.

[0003] The existing slope protection methods, such as geotechnical materials, grid nets, steel rope nets and other hard materials, mainly achieve the support and fixation of the slope through physical structural protection; however, these hard protection solutions usually have poor water permeability, which can easily cause water accumulation in the slope, leading to soil saturation and instability. In addition, as one example, the patent with publication number CN117071500A discloses a slope protection device and support method for the reservoir water level rapid change area, which also has the above problems.

[0004] Using vegetation roots to stabilize the soil can reduce soil erosion and restore the ecological function of the slope. However, a single vegetation restoration solution faces great challenges in the drawdown zone where the water level changes rapidly, especially in an environment with high water levels that rise and fall sharply. It is difficult for plants to take root quickly, resulting in low vegetation coverage and survival rates. Nutrients are easily lost under the scouring of water, making it difficult to provide long-term protection.

[0005] The above technical problems need to be solved. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1

[0036] like Figures 1 to 7As shown: This embodiment provides a reservoir microbial nutrition supply type ring protection slope system, which includes a plurality of protection units connected in sequence and fixed to 1 through an anchoring device, each of which includes a geonet 2, a geotextile 3, a grid net 4 and a steel rope net 5 arranged in sequence from bottom to top. Figure 1 The orientation shown is the standard; geonet 2 and geotextile 3 provide filtering and soil erosion prevention functions, the grid enhances structural stability, and the steel rope net 5 provides high-strength impact protection. This multi-layer structure effectively resists slope sliding and water erosion, and is the core physical support part of the protection system.

[0037] The slope protection system is composed of several protective layers with different functions, which are fixed by anchoring devices (the anchoring devices run through the multi-layer protection system and tightly combine each layer of material with 1) to form a protection unit. The overall structure is composed of several protection units arranged in an array.

[0038] Geonet 2, geotextile 3, and grid 4 all use porous single-layer materials; geotextile 3 can be set as one layer, geonet 2 can be set as one layer, grid 4 can be set as two layers, and steel rope net 5 can be set as one layer. For example, geonet 2 can use CE131 type, grid 4 uses 10% aluminum-zinc alloy coated steel wire, and is coated with a PVC layer on the surface; steel rope net 5 uses 10% aluminum-zinc alloy coated steel wire rope, and is coated with a PVC layer on the surface; geotextile 3 uses basalt fiber geotextile 3, the surface is densely covered with holes of 3-5mm in diameter, and double-layer welding makes it have excellent tensile strength and puncture resistance. The preparation density generally shows a relatively dense distribution in the center of the protection unit and a relatively sparse distribution around it. In order to reduce the flooding effect of water flow on vegetation during the flood season, the steel rope net 5 should also adopt a distribution method with high in the middle and low around it.

[0039] The present embodiment provides a reservoir microbial nutrient supply type ring protection slope system, the main improvement of which is that the protection unit also includes a microbacteria layer and an ecological layer which are arranged between two layers of grid nets from bottom to top; the microbacteria layer is composed of a plurality of microbial filling bags 7, and the ecological layer is composed of a plurality of plant seed filling bags 6.

[0040] The body of the microorganism filling bag 7 is made of non-woven fabric and is flat. The body of the microorganism filling bag 7 is filled with sandy loam, volcanic rock debris and a small amount of water-retaining polymer, and appropriate amounts of actinomycetes and spore-forming bacteria are added. The microorganism filling bag 7 can form a microbacteria layer by staggered stacking.

[0041] The bag body of the plant seed filling bag 6 is made of porous non-woven fabric and contains sandy loam, organic fertilizer and water-resistant plant seeds; for example, seeds of Salix babylonica, Euphorbia milii or other water-resistant trees and shrubs are used. The plants grow naturally in the bag body, and the roots penetrate the bag body and various layers of protective materials, penetrate into the soil, and merge with the protective layer below.

[0042] The system also includes a natural self-generated nutrient slow-release device and a drainage device. The natural self-generated nutrient slow-release device is used to transport moisture and microorganisms in the external natural water body to the microbacteria layer, and the drainage device is used to divert excess moisture in the ecological layer to the outside.

[0043] The natural self-generated nutrient slow-release device includes a PVC tube 28 and a porous ceramic rod 27. The PVC tube 28 is provided with a plurality of through holes which penetrate the microbacteria layer. The porous ceramic rod 27 is embedded in the PVC tube 28 and its lower end extends out from the lower end of the PVC tube 28 and is thickened. The externally-placed thickened portion of the porous ceramic rod 27 penetrates into the natural water body. Through the capillary action of the porous ceramic rod 27, the water in the natural water body is transported to the PVC tube 28 together with the microorganisms, and is slowly released into the microbacteria layer through the gaps in the pipeline. Through the metabolism of bacteria, the microorganisms in the natural water body can be decomposed into nutrients that can be absorbed by plant roots. The upper end of the PVC tube 28 can also be sealed with a cap, and the cap can be opened manually to add suitable nutrients.

The diversion pipe 11 is fixed to the pipe groove opened on 1. The lower end of the water inlet pipe 10 is connected to the diversion pipe 11, and the upper end extends into the ecological layer (middle or bottom). The upper end of the outlet pipe 12 is connected to the diversion pipe 11, and the lower end extends to the outside. The drainage device can discharge the water accumulated inside the slope in time to avoid structural instability caused by soil saturation. A diversion pipe 11 can be arranged in parallel every 1.5m at a distance of 1.5m from the edge of the protection unit, and a water inlet pipe 10 can be arranged every 1m along the diversion pipe 11. The water inlet diameter is 2 to 4cm, and the diameter of the diversion pipe 11 is 4 to 6cm. The two are connected by bonding.

[0045] In this embodiment, the anchoring device includes first anchor rods 8 arranged at the four corners of the protection unit.

The edge of the protection unit is sutured by suture ropes 16 and tied and sutured with the longitudinal support ropes 15 and transverse support ropes 14 by suture ropes 16. The first anchor rods 8 ensure that the protection unit remains stable and does not slip under water erosion, and monitors the health condition at the same time. Rings are set at both ends of the transverse support ropes 14 and the longitudinal support ropes 15, and a support rope is set between every two adjacent flying wing 18-type anchor rods, which are fixed by the rings.

[0046] In this embodiment, the lower end of the first anchor rod 8 is movably sleeved with a short sleeve 25 and a wing 18 rotatably connected, the sleeve is connected with a withdrawal rope 26, the wing 18 is arranged between the short sleeve 25 and the first anchor rod 8 and is compressed by the sleeve to be parallel to the first anchor rod 8; when the short sleeve 25 is pulled by the withdrawal rope 26 and moves along the axial direction of the first anchor rod 8 to be separated from the wing 18, the wing 18 is reset to be inclined to the axis of the first anchor rod 8 under the elastic force. The spacing between the holes of the first anchor rod 8 can be arranged according to 4.5×4.5m; the wing 18 is used for self-locking fixation, and can be inserted into the soil after being released (grasp the hole wall after popping out) to improve the anchoring effect.

[0047] In this embodiment, the first anchor rod 8 is a double-layer rod structure, and the outer side wall of the bottom end of the outer rod (hollow structure) is provided with a wing groove 24 for accommodating the flying wing 18, and a radially arranged elastic wing lock 22 is also installed between the outer rod and the inner rod, and the outer end of the elastic wing lock 22 is tightly against the inner wall of the flying wing 18; the elastic wing lock 22 is made of 60Si2Mn spring steel, and its tensile strength is not less than 1200MPa;.

[0048] In this embodiment, a structural glue box 21 is provided at the lower end of the inner rod of the first anchor rod 8, and the structural glue box 21 is filled with structural glue. The bottom end of the outer rod is a quadrangular pyramid structure and is provided with a glue release hole 19 for the structural glue to flow out. The flow channel 23 of the structural glue box 21 is blocked by a plug and the plug is linked with the elastic wing lock 22. When the elastic wing lock 22 is reset, the plug releases the flow channel 23. The plug at one end of the elastic wing lock 22 close to the central axis is preferably made of a material that is not suitable for bonding with structural glue and is corrosion-resistant, such as silicone and polytetrafluoroethylene.

[0049] In this embodiment, a fiber optic sensor 20 for monitoring the stress condition is also wound on the inner rod of the first anchor rod 8; the fiber optic sensor 20 can be, for example, HKS-S400 type, which is evenly spirally wound on the outer surface of the inner rod; the fiber optic sensor 20 can be connected to an external host computer through a sensor wire 17 to realize data transmission.

[0050] In this embodiment, the anchoring device further includes a second anchor rod 9, which penetrates the protective unit and tightly connects the ecological layer and the microbacterial layer to 1. The second anchor rod 9 can be a short anchor, and the rod is usually a threaded steel bar with a diameter of 16 to 20 mm and a length of 0.5 to 1 m. The second anchor rod 9 is arranged in a plum blossom shape along 1 at intervals of 2 to 3 m to ensure that it can effectively fix the ecological layer and the microbacterial layer.
