Description

Technical Field

[0001] This utility model relates to the field of slope maintenance technology, specifically to a revegetation structure for highway slopes. Background Technology

[0002] As a crucial component of modern transportation infrastructure, highways play an irreplaceable role in driving regional economic development and facilitating the flow of people and goods. However, their construction often involves large-scale terrain modification, particularly the excavation and filling of mountains, resulting in numerous artificial slopes. These slopes, in the short term, damage the original natural landscape and ecosystem, leading to vegetation loss, exposed topsoil, and exacerbated soil erosion. They may even trigger geological disasters such as landslides and collapses, seriously threatening road operational safety and the surrounding ecological environment. Currently, ecological restoration of highway slopes primarily employs slope revegetation technology, aiming to restore vegetation cover through artificial intervention, enhance slope stability, improve landscape effects, and achieve the gradual reconstruction of the ecosystem.

[0003] However, existing revegetation techniques generally involve directly sowing grass seeds or laying turf. While these methods are simple to operate and low in cost, they are suitable for areas with gentle slopes and good soil quality. On steep or rocky slopes, grass seeds are difficult to adhere to and are easily washed away by rainwater. Turf, on the other hand, has a weak root system that cannot penetrate deep into the rock layer, resulting in poor soil stabilization and a low survival rate. Therefore, a highly stable revegetation structure for highway slopes is needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a highway slope revegetation structure with high stability.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a highway slope revegetation structure, including anchor bolts, a steel base plate, an ecological frame, ecological bags, and a reinforcement mechanism;

[0006] Multiple anchor rods are evenly arranged on the bottom surface of the steel base plate, and an open ecological frame is set on the top surface. The ecological bag is filled with ecological substrate for plant growth. After the ecological bag is placed in the ecological frame, it is stabilized by a limiting mechanism.

[0007] The reinforcement mechanism is installed on the steel base plate to enhance the overall structural stability of the slope. After the steel base plate is initially fixed by inserting anchors into the slope soil layer, the reinforcement mechanism injects reinforcement material for secondary reinforcement and overall anchoring.

[0008] As an improvement, the limiting mechanism includes a limiting plate, which is detachably installed on the top of the ecological frame and fastened to the ecological frame by bolts, so that the ecological bag is pressed and limited within the ecological frame;

[0009] Multiple vegetation grooves are evenly distributed on the limiting plate to allow plant stems and leaves to pass through and guide their directional growth, while also enhancing the air and water permeability between the limiting plate and the ecological bag.

[0010] As improvements, drainage channels and absorbent sponges are also included;

[0011] Absorbent sponges are laid on the top surface of the steel base plate and below the eco-bag to absorb and store rainwater or irrigation water and regulate the humidity inside the eco-bag.

[0012] Drainage channels are evenly distributed on the four sides of the ecological frame to drain excess water from inside the ecological bag, preventing water accumulation that could lead to root rot or structural instability. The water-absorbing sponge fits tightly against the ecological bag, forming a "storage-drainage" synergistic water regulation system.

[0013] As an improvement, the reinforcement mechanism includes a grouting groove and grouting holes;

[0014] Grouting grooves are opened in pairs inside the reinforced base plate and extend along its length; grouting holes penetrate the upper surface of the reinforced base plate and are connected to the grouting grooves; reinforced concrete grout is injected through the grouting holes, and the grout flows into the grouting groove and spreads to the surrounding area, filling the gap between the reinforced base plate and the slope surface to form a rigid connection layer.

[0015] As an improvement, the reinforcement mechanism also includes cylindrical grooves and reinforcement holes;

[0016] Each anchor has a cylindrical groove connected to the grouting groove along the axial direction inside; multiple reinforcement holes connected to the cylindrical groove are evenly distributed on the side wall of the anchor; the grout enters the grouting groove through the grouting hole, then flows into the cylindrical groove, and seeps into the deep soil and rock mass of the slope through the reinforcement hole, forming a three-dimensional grouting reinforcement network of "surface-line-point", which significantly improves the anchoring force and the overall stability of the slope.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. By using anchor bolts, steel base plates, and secondary grouting reinforcement, "preliminary anchoring and secondary strengthening" are achieved. The grouting groove, columnar groove, and reinforcement holes form a three-dimensional grouting network. The grout penetrates into the deep soil and rock mass, forming a surface-line-point three-dimensional reinforcement system, which significantly improves the overall stability.

[0019] 2. The synergistic design of the absorbent sponge and drainage channel forms a "storage-drainage" coordinated moisture regulation system to regulate the humidity inside the eco-bag;

[0020] 3. The detachable limiting mechanism facilitates later maintenance and replacement of the eco-bag. Attached Figure Description

Multiple anchor rods 1 are evenly distributed on the bottom surface of the steel base plate 2, and an open-top ecological frame 3 is provided on the top surface. The ecological bag 4 is filled with ecological substrate for plant growth. After the ecological bag 4 is placed inside the ecological frame 3, it is stabilized by a limiting mechanism, which includes a limiting plate 5. The limiting plate 5 is detachably installed on the top of the ecological frame 3 and fastened to the ecological frame 3 with bolts, thus pressing and confining the ecological bag 4 within the ecological frame 3. Multiple vegetation grooves 6 are evenly distributed on the limiting plate 5 to allow plant stems and leaves to pass through and guide their directional growth, while also enhancing the air and water permeability between the limiting plate 5 and the ecological bag 4.

[0029] Drill holes in the slope as needed. After drilling, insert anchor rod 1 into the slope soil layer to achieve initial anchoring. Place ecological bag 4 filled with improved soil, organic fertilizer, water-retaining agent and plant seeds into ecological frame 3. Place limiting plate 5 on top of ecological frame 3 and tighten it with bolts. The vegetation groove 6 on the limiting plate 5 allows plant stems and leaves to pass through, while preventing ecological bag 4 from shifting.

[0030] It also includes a reinforcement mechanism; the reinforcement mechanism is set on the steel base plate 2 to enhance the overall structural stability of the slope; after the steel base plate 2 is initially fixed by each anchor rod 1 inserted into the slope soil layer, the reinforcement mechanism injects reinforcement material for secondary reinforcement and overall anchoring. The reinforcement mechanism includes grouting grooves 9 and grouting holes 10; the grouting grooves 9 are opened in pairs inside the steel base plate 2 and extend along its length; the grouting holes 10 penetrate the upper surface of the steel base plate 2 and are connected to the grouting grooves 9; reinforced concrete grout is injected through the grouting holes 10, and the grout flows into the grouting grooves 9 and spreads to the surroundings, filling the gap between the steel base plate 2 and the slope surface to form a rigid connection layer;

[0031] Reinforced concrete grout is injected into the grouting groove 9 inside the reinforcing steel base plate 2 through the grouting hole 10. The grout spreads along the grouting groove 9, filling the gap between the reinforcing steel base plate 2 and the slope, forming a rigid connection layer, and improving the anchoring force and overall stability.

[0032] Example 2

[0033] Based on Example 1, combined with Appendix Figure 3 As shown, it also includes drainage channels 7 and water-absorbing sponges 8; the water-absorbing sponges 8 are laid on the top surface of the steel base plate 2 and located below the ecological bag 4, used to absorb and store rainwater or irrigation water, and regulate the humidity inside the ecological bag 4; the drainage channels 7 are evenly opened on the four sides of the ecological frame 3, used to drain excess water from the inside of the ecological bag 4, preventing water accumulation from causing root rot or structural instability. The water-absorbing sponges 8 are closely attached to the ecological bag 4, forming a "storage-drainage" coordinated water regulation system.

[0034] The reinforcement mechanism also includes columnar grooves 11 and reinforcement holes 12; each anchor rod 1 has a columnar groove 11 connected to the grouting groove 9 along the axial direction inside; multiple reinforcement holes 12 connected to the columnar grooves 11 are evenly distributed on the side wall of the anchor rod 1; the grout enters the grouting groove 9 through the grouting hole 10, then flows into the columnar groove 11, and seeps into the deep rock and soil of the slope through the reinforcement hole 12, forming a three-dimensional grouting reinforcement network of "surface-line-point", which significantly improves the anchoring force and the overall stability of the slope.

[0035] In the specific implementation of this utility model, firstly, the loose stones and soil on the slope surface are cleaned, and the slope surface is trimmed to a flat surface. After drilling, the anchor rod 1 is inserted into the slope rock and soil layer to achieve preliminary anchoring. Reinforced concrete grout is injected into the grouting groove 9 in the steel base plate 2 through the grouting hole 10. The grout spreads along the grouting groove 9, filling the gap between the steel base plate 2 and the slope to form a rigid connection layer. At the same time, the grout flows into the interior of the anchor rod 1 through the columnar groove 11 and seeps into the deep rock and soil through the reinforcement hole 12 on the side wall to form a three-dimensional grouting network, which greatly improves the anchoring force and overall stability.

[0036] A water-absorbing sponge 8 is laid on the top surface of the steel base plate 2 to ensure that it is in close contact with the plate surface. The water-absorbing sponge 8 stores rainwater or irrigation water. Then, an ecological bag 4 filled with improved soil, organic fertilizer, water-retaining agent and plant seeds is placed in the ecological frame 3. The limiting plate 5 is placed on the top of the ecological frame 3 and fastened with bolts. The vegetation groove 6 on the limiting plate 5 allows plant stems and leaves to pass through, while preventing the ecological bag 4 from shifting.

[0037] Initially, water can be sprayed manually for maintenance. The water-absorbing sponge 8 slowly releases water to maintain the humidity of the ecological bag 4. Plants grow through the vegetation trough 6, gradually forming a stable vegetation community. If replanting or replacement is needed, the limiting plate 5 can be removed for easy operation.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
