Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a portable rigid ecological grid system. Background Technology

[0002] For the management of geological hazards such as landslides and rockfalls on slopes, traditional grid mesh is commonly used to intercept falling rocks and other debris, preventing and mitigating related geological disasters. However, current grid mesh protection systems have low buffering capacity and complex structures, requiring grouting through drilling in the soil and rock mass, making installation difficult and time-consuming. This is particularly problematic in railway construction areas where there are maintenance windows for train traffic. The equipment required for traditional drilling and grouting anchoring techniques would interfere with train passage, necessitating consideration of these maintenance windows during construction. Furthermore, traditional drilling and grouting anchoring techniques are limited by terrain conditions; in remote or steep areas, drilling and grouting equipment cannot be used or installed. Utility Model Content

[0003] To address the aforementioned issues, this application provides a portable rigid ecological grid system that is easy to construct and has a short construction period.

[0004] The objective of this utility model is achieved through the following technical solution: a portable rigid ecological grid system, comprising:

[0005] Several fixed structures arranged at intervals, several steel strands connected in series with all the fixed structures and distributed vertically, and a protective net connected to the fixed structures and steel strands.

[0006] The fixed structure includes steel columns anchored to the ground by steel bar rivets, reinforcing bars tied to the lower part of the steel columns, and a concrete foundation poured into the reinforcing bars and the lower part of the steel columns; the upper ends of the steel bar rivets are also tied to the reinforcing bars and are poured into the concrete foundation; the steel strands connect all the steel columns of the fixed structure.

[0007] The fixing structure formed by the steel rivets, steel columns, reinforcing bars, and concrete foundation of this utility model can effectively fix the protective netting. The steel rivets are anchored into the soil by hammering and impact, eliminating the need for drilling and grouting, thus minimizing the impact on vehicle traffic during construction within the railway area. Furthermore, the installation process, which does not require drilling and grouting, has minimal impact on the terrain and meets the requirements of ecological and environmental protection.

[0008] At least two of the end fixed structures have diagonal braces attached to their steel columns; one end of each diagonal brace is connected to a steel column, and the other end is anchored to the ground. The diagonal braces enhance the stability of the fixed structure.

[0009] A reinforcing plate is anchored between two adjacent fixed structures, and all steel strands pass through the reinforcing plate. The reinforcing plate connects the vertically distributed steel strands together, reducing their sway and making the protective net more stable.

[0010] The steel column is an H-beam.

[0011] The protective net is fixed to the steel column by a clamping structure; the clamping structure includes an L-shaped clamping member bolted to the steel column and a clamping plate bolted to the L-shaped clamping member; the edge of the protective net is clamped between the L-shaped clamping member and the clamping plate.

[0012] The portable rigid ecological grid system also includes an ecological restoration blanket laid on the ground, with the fixing structure located above the ecological restoration blanket.

[0013] The ecological restoration blanket is fixed to the ground by several steel rivets.

[0014] The ecological restoration blanket includes, from top to bottom, an anti-erosion layer, a seed layer, a microbial water regulation layer, and a root guiding layer.

[0015] The upper surface of the erosion-resistant layer is sprayed with sodium alginate / nano SiO2 solution.

[0016] The erosion-resistant layer includes a sodium alginate gel layer embedded with an anti-UV glass fiber mesh;

[0017] The seed layer is a mixture of plant seeds and slow-release fertilizer, wherein the density of plant seeds is 50-80 seeds / dm2.

[0018] The bacterial water regulation layer is a porous layer with added water-retaining agent and microbial carrier;

[0019] The root guiding layer is a honeycomb PLA starch substrate.

[0020] This invention can reduce soil erosion and promote vegetation growth by setting up ecological restoration blankets, thus playing a good role in ecological restoration.

[0021] Compared with the prior art, this application has the following beneficial effects:

[0022] (1) The fixing structure formed by the steel rivets, steel columns, basket reinforcement and concrete foundation of this utility model can fix the protective net well. The steel rivets can be anchored into the soil by hammering and impact, without drilling and grouting. The construction within the railway area has little impact on vehicle traffic. At the same time, the installation process does not require drilling and grouting, which has little impact on the topography and meets the requirements of ecological and environmental protection.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0033] Example 1

[0034] like Figure 1-3As shown, this embodiment discloses a portable rigid ecological grid system, which includes: a fixed structure, steel strands 5, and a protective net 3. The fixed structure has at least two components; if the slope to be protected is wide, the number of fixed structures can be increased, and the fixed structures are arranged at intervals. The steel strands 5 connect all the fixed structures in series; there are multiple steel strands 5, distributed vertically. The protective net 3 is connected to the fixed structure and the steel strands 5. The protective net 3 can be a single unit or composed of multiple protective net units. In this embodiment, the protective net 3 is composed of multiple protective net units. During installation, one protective net unit is installed between two adjacent fixed structures, and then the protective net unit is fixed to the steel strands 5 using shackles. Thus, the fixed structure, the steel strands 5, and the protective net 3 form a single protective structure.

[0035] like Figure 1 , 2 As shown, the fixed structure includes a steel column 2 anchored to the ground by steel bar rivets 8, a basket reinforcement bundled at the lower part of the steel column 2, and a concrete foundation 1 poured at the lower part of the basket reinforcement bundle and the steel column 2; the upper end of the steel bar rivet 8 is also bundled with the basket reinforcement bundle and is poured into the concrete foundation 1; the steel strand 5 connects all the steel columns 2 of the fixed structure.

[0036] In practice, the steel column 2 is first anchored to the ground using steel rivets 8. Then, a certain number of reinforcing bars are tied to the base of the steel column 2, and these reinforcing bars are tied together with the steel rivets 8. Finally, a concrete foundation 1 is poured outside the steel column 2, so that the base of the steel column 2, the reinforcing bars, and the upper ends of the steel rivets 8 are all poured into the concrete foundation 1, thus forming a fixed structure. In addition, before installing the steel column 2, the steel cable 5 must be connected to the steel column 2 before pouring the concrete foundation 1. In practice, one end of the steel cable 5 is fixed to the steel column 2 at one end using a steel cable lock, and the other end of the steel cable 5 passes through the steel column 2 in the middle and is then fixed to the steel column 2 at the other end using a steel cable lock.

[0037] In this embodiment, the steel column 2 is an H-beam. During installation, the protective netting 3 is fixed to the steel column 2 using a clamping structure. Specifically, as shown... Figure 4 As shown, the clamping structure includes an L-shaped clamping member 9 bolted to the steel column 2 and a clamping plate 10 bolted to the L-shaped clamping member 9; the edge of the protective net 3 is clamped between the L-shaped clamping member 9 and the clamping plate 10. During installation, the protective net 3 can be fixed to the steel column 2 using multiple clamping structures.

[0038] In addition, during implementation, a reinforcing plate 6 can be anchored between two adjacent fixed structures, with all steel strands 5 passing through the reinforcing plate 6. The reinforcing plate 6 can connect the vertically distributed steel strands 5 together, reducing the swaying of the steel strands 5 and making the protective net 3 more stable.

[0039] At least two of the end fixed structures have diagonal braces 4 connected to their steel columns 2; one end of each diagonal brace 4 is connected to the steel column 2, and the other end is anchored to the ground. That is, each steel column 2 on the fixed structure can be connected to a diagonal brace 4, or only some of the steel columns 2 on the fixed structure can be connected to diagonal braces 4, such as the two end fixed structures on both sides having diagonal braces 4 connected to them. The auxiliary support of the diagonal braces 4 further improves the stability of the fixed structure.

[0040] In this embodiment, the portable rigid ecological grid system, consisting of steel rivets 8, steel columns 2, reinforcing bars, and a concrete foundation 1, forms a fixing structure that effectively secures the protective netting 3. The steel rivets 8 are 50cm long and can be driven into the soil by hammering, eliminating the need for drilling and grouting. This minimizes the impact on vehicle traffic during construction within the railway area. Furthermore, the installation process, which eliminates the need for drilling and grouting, has minimal impact on the terrain, thus meeting ecological and environmental protection requirements.

[0041] Example 2

[0042] The portable rigid ecological grid system of this embodiment, based on embodiment 1, further includes an ecological restoration blanket 7 laid on the ground, and the fixing structure is located above the ecological restoration blanket 7, such as... Figure 1 , 2 As shown.

[0043] During installation, the ecological restoration blanket 7 is also fixed to the ground with several steel rivets 8, so that the ecological restoration blanket 7 fits the ground.

[0044] Specifically, such as Figure 5 As shown, the ecological restoration blanket 7 includes an anti-erosion layer 71, a seed layer 72, a microbial water regulation layer 73, and a root guiding layer 74, which are bonded together from top to bottom.

[0045] The erosion-resistant layer 71 includes a sodium alginate gel layer embedded with a UV-resistant glass fiber mesh, which is 12 mm thick and has a pore size of 5 mm. This erosion-resistant layer 71 can reduce soil erosion on the ground.

[0046] Seed layer 72 is a mixed layer of plant seeds and slow-release fertilizer. Specifically, seed layer 72 is composed of a high-toughness fiber network layer of rice husk / coconut husk fiber (particle size 0.5-1mm) after alkali treatment, on which plant seeds and slow-release fertilizer are laid. The density of plant seeds is 50-80 seeds / dm2.

[0047] The bacterial water regulation layer 73 is a porous layer with added water-retaining agent and microbial carrier; that is, the microbial carrier is loaded on porous ceramic particles, and the water-retaining agent is added to the porous ceramic particle layer. Among them, the microbial carrier consists of nitrogen-fixing bacteria, phosphate-solubilizing bacteria, and arbuscular mycorrhizal fungal spores, with a bacterial content of ≥10^6 CFU per gram of material.

[0048] The root guiding layer 74 is a honeycomb PLA starch substrate, wherein the honeycomb grooves are 3mm deep and spaced 10mm apart.

[0049] As an optional implementation of this embodiment, an electrostatic spraying technique is used to spray a sodium alginate / nano SiO2 solution onto the upper surface of the erosion-resistant layer 71 to achieve a better water-locking effect.

[0050] This embodiment can reduce soil erosion and promote vegetation growth by setting up ecological restoration blankets, thus playing a good role in ecological restoration. In addition, the materials degrade and are converted into organic matter, avoiding secondary pollution.
