Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of slope protection technology, and more specifically, to a slope protection structure for municipal auxiliary roads. Background Technology

[0002] In existing technologies, traditional vegetation slope protection relies on the root system of vegetation to fix the soil and enhance the stability of the slope. However, in areas with low soil strength, steep slopes, or strong rain erosion, simple vegetation slope protection often cannot provide sufficient support, which can easily lead to the destruction of vegetation and a significant reduction in the effectiveness of slope protection.

[0003] Simple vegetation protection relies solely on the root system to stabilize the soil. When soil strength is low, the root system cannot provide sufficient support, leading to easy deformation and damage of the slope. Therefore, a more stable slope protection structure for municipal auxiliary roads is designed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a municipal auxiliary road slope protection structure.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a municipal auxiliary road slope protection structure, including a slope protection surface and a greening carpet overlapping the slope protection surface. A reinforcing layer is also provided between the slope protection surface and the greening carpet. The reinforcing layer is laid on the slope protection surface. A filling layer is filled between the reinforcing layer and the greening carpet. The filling layer is placed on the reinforcing layer. A solidification layer for enhancing the strength of the soil is filled between the reinforcing layer and the slope protection surface.

[0007] An anchor is provided between the greening blanket and the slope protection surface to anchor the greening blanket to the slope protection surface. The anchor includes two sleeves, a screw, and a connecting rod for connecting the sleeves.

[0008] Preferably, the reinforcing layer is a steel mesh, and a plurality of reinforcing columns are welded to the bottom of the steel mesh, and the bottom end of the reinforcing column is welded with a tapered end for insertion into the slope surface of the slope protection.

[0009] Preferably, the outer surface of the conical end is provided with at least three reinforcing plates along the circumferential direction, the upper end of the reinforcing plate is welded to the outer surface of the conical end, and the bottom end of the reinforcing plate is conical.

[0010] Preferably, there is a gap between the lower end of the reinforcing plate and the tapered end, and both the reinforcing column and the reinforcing plate are made of steel.

[0011] Preferably, the filling layer is one of nutrient soil, organic matter or fertilizer, and the solidification layer is a soil stabilizer.

[0012] Preferably, the anchor passes through the greening blanket and extends into the slope surface, and the overlap of two adjacent greening blankets is anchored by the anchor.

[0013] Preferably, the sleeve includes a straight cylindrical section, a bent section for deformation anchoring, and a movable end for controlling the movement of the bent section. The straight cylindrical section has a "T" shaped cross-section, and the movable end is sleeved on the outside of the screw.

[0014] Preferably, the bending section is made of carbon steel or stainless steel, and a bending portion is provided in the middle of the bending section. The initial state of the bending section is vertical.

[0015] Preferably, the two ends of the bent section are welded to the straight section and the movable end head respectively, and the movable end head is threadedly engaged with the screw.

[0016] Preferably, the upper ends of two adjacent screws are provided with connecting rods, the connecting rods are U-shaped, and the upper ends of the screws are provided with cross grooves for insertion with the connecting rods.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) By filling the soil between the reinforcing layer and the slope surface with soil stabilizer, this utility model significantly improves the soil density and reduces the risk of slope deformation and damage. At the same time, spraying the stabilizer and laying the filling layer can effectively reduce water and soil loss caused by rainwater erosion and wind erosion, and maintain the integrity of the slope.

[0019] (2) This utility model further enhances the anchoring force by designing the anchor and controlling the expansion of the bending section by rotating the screw, thus ensuring the stability of the green carpet.

[0020] The aforementioned beneficial effects effectively solve the problem of insufficient stability of traditional vegetation slope protection under complex conditions, and improve the overall performance and reliability of slope protection.

[0030] like Figure 1-5 As shown, this utility model provides a municipal auxiliary road slope protection structure, including a slope protection surface 1 and a greening blanket 2 overlapping the slope protection surface 1. A reinforcing layer 3 is also provided between the slope protection surface 1 and the greening blanket 2. The reinforcing layer 3 is laid on the slope protection surface 1. A filling layer 4 is filled between the reinforcing layer 3 and the greening blanket 2. The filling layer 4 is set on the reinforcing layer 3. A solidification layer 6 for enhancing the strength of the soil is filled between the reinforcing layer 3 and the slope protection surface 1.

[0031] An anchor 5 is provided between the greening blanket 2 and the slope protection surface 1 to anchor the greening blanket 2 to the slope protection surface 1.

[0032] Furthermore, in this embodiment, the reinforcing layer 3 is a steel mesh 301, and a plurality of reinforcing columns 302 are welded to the bottom of the steel mesh 301. The bottom end of the reinforcing column 302 is welded with a conical end 303 for insertion into the slope surface 1. The reinforcing layer 3 of the steel mesh 301 increases the connection strength between the green carpet 2 and the slope, preventing the green carpet 2 from being washed away by water or displaced due to the unevenness of the slope surface. The reinforcing columns 302 enable the steel mesh 301 to be inserted into the slope surface 1 instead of being laid on the slope surface 1, thereby improving the connection firmness between the reinforcing layer 3 and the slope surface 1.

[0033] In this embodiment, at least three reinforcing plates 304 are provided circumferentially on the outer surface of the conical end 303. The upper end of the reinforcing plate 304 is welded to the outer surface of the conical end 303, and the bottom end of the reinforcing plate 304 is conical. The conical end 303 allows the reinforcing column 302 to be better inserted into the slope protection surface 1. The conical bottom end of the reinforcing plate 304 increases the contact portion between the reinforcing column 302 and the slope protection surface 1, thereby improving the firmness.

[0034] In this embodiment, there is a gap between the lower end of the reinforcing plate 304 and the conical end 303. This gap allows the reinforcing plate 304 to be fully inserted into the slope surface 1 when the conical end 303 of the reinforcing column 302 is inserted. Both the reinforcing column 302 and the reinforcing plate 304 are made of steel, which improves the strength of the reinforcing column 302 and the reinforcing plate 304.

[0035] It should be noted that strengthening 304 is not limited to Figure 3 The arc-shaped state shown can also be a straight state.

[0036] In this embodiment, the filling layer 4 is one of nutrient soil, organic matter, or fertilizer, or the nutrient soil, organic matter, or fertilizer are mixed evenly according to the design ratio to make a substrate suitable for vegetation growth. The selection is made according to the actual situation. The filling layer 4 provides the nutrients needed for the growth of the plants in the green carpet 2, and can also increase the friction between the green carpet 2 and the slope protection, so that the green carpet 2 and the slope protection are more closely attached and the stability of the slope protection is improved. The solidification layer 6 is a soil solidifier. By filling the soil solidifier between the reinforcing layer 3 and the slope surface 1, the soil solidifier will penetrate into the soil after being sprayed on the slope surface 1, and combine with the soil particles to improve the soil strength.

[0037] It should be noted that the soil stabilizer should be a non-toxic, harmless, and pollution-free environmentally friendly soil stabilizer, such as Lubang EN-1 soil stabilizer. This type of stabilizer will not damage the soil and the surrounding ecological environment during use, and is conducive to the growth of vegetation and the restoration of the ecosystem. Soil stabilizers with less impact on plant growth, such as some polymer stabilizers, can improve soil strength and stability without significantly affecting soil pH and the germination rate of plant seeds.

[0038] When filling soil stabilizer, strictly follow the instructions in the product manual to ensure that the dosage and mixing uniformity of the stabilizer meet the requirements.

[0039] In this embodiment, the anchor 5 passes through the greening blanket 2 and extends into the slope surface 1. The overlap of two adjacent greening blankets 2 is anchored by the anchor 5. The anchor 5 includes two sleeves 501, a screw 502 and a connecting rod 506 for connecting the sleeves 501. The sleeves 501 and the screw 502 are threaded together.

[0040] In this embodiment, the sleeve 501 includes a straight cylindrical section, a bent section 503 for deformation anchoring, and a movable end 504 for controlling the movement of the bent section 503. The straight cylindrical section has a "T" shaped cross-section, and the movable end 504 is sleeved on the outside of the screw 502. The straight cylindrical section abuts against the screw 502 but is not threadedly connected to the screw 502. The bent section 503 has no contact with the screw 502, and the movable end 504 is directly connected to the screw 502.

[0041] In this embodiment, the bending section 503 is made of carbon steel or stainless steel. A bending part 505 is provided in the middle of the bending section 503. The initial state of the bending section 503 is vertical. Based on the material of the bending section 503 and the bending part 505, the bending section 503 is bent. When the bending section 503 enters the slope protection area, it is in the initial state.

[0042] In this embodiment, the two ends of the bent section 503 are welded to the straight section and the movable end 504, respectively. The movable end 504 is threadedly engaged with the screw 502. When the slope protection structure is completed and the green blanket 2 needs to be anchored, a hole is drilled at the anchoring position. The sleeve 501 and the screw 502 in the initial state are assembled and inserted into the hole. Using a tool, such as a screwdriver adapted to the screw 502, the screw 502 is rotated. The rotation of the screw 502 controls the movable end 504 to move upward, which in turn drives the lower end of the bent section 503 to move upward as well. At this time, the bent part 505 expands outward and squeezes the soil at the contact position with the slope protection. The required tightening height of the bent section 503 is selected according to the actual situation of the slope protection until the requirements are met, and then the screw 502 is stopped from rotating.

[0043] It should be noted that since the screw 502 is inserted deep into the slope protection, a measuring tool, such as a measuring ruler, can be used to measure the distance between the screw 502 and the outer end of the hole after rotating it several times to determine the screw 502's screw-out height. This ensures accuracy and that the screw 502's screw-out height meets the design requirements.

[0044] In this embodiment, a connecting rod 506 is provided at the upper end of two adjacent screws 502. The connecting rod 506 has a "U" shape design. The upper end of the screw 502 is provided with a cross groove 507 for insertion with the connecting rod 506. After the screw 502 is rotated into place, the U-shaped connecting rod 506 is inserted into the hole and passes through the green carpet 2, connecting the two screws 502 at the overlap of the green carpet 2, thereby anchoring the adjacent green carpet 2.

[0045] In addition, considering the firmness of the connection between the connecting rod 506 and the screw 502, the screw 502 is inserted into the connecting rod 506. The insertion depth of the screw 502 must be at least half the length of the vertical part of the U-shaped connecting rod 506 to ensure the connection is firm.

[0046] Specifically, first remove debris, loose soil, stones, etc. from the slope surface 1 to ensure it is flat and firm. Then, lay the steel mesh 301 on the slope surface 1, ensuring it adheres tightly to the surface. Use a hammer or other tools to drive the tapered ends 303 of the steel mesh 301 into the slope surface 1, ensuring the reinforcing posts 302 and tapered ends 303 are firmly inserted. Finally, use a sprayer to evenly spray the prepared soil stabilizer onto the steel mesh 301 (the soil stabilizer needs to be applied as needed). Since dilution is required, it needs to be diluted with water according to the actual situation to meet the needs of the slope protection structure. Ensure that the curing agent fully penetrates into the soil and the steel mesh 301. After the curing agent has cured for 24 hours or longer, use a hydroseeding machine to evenly spray the filling layer 4 onto the steel mesh 301 to form a filling layer 4 of a certain thickness. After the filling layer 4 has stabilized (the stabilization time is determined according to the material of the filling layer 4), lay the greening blanket 2 flat on the filling layer 4, ensuring that it adheres tightly to the filling layer 4.

[0047] At the overlap of the green carpet 2, ensure that the overlap width of two adjacent green carpets 2 meets the design requirements. Drill holes at the anchoring positions using a drilling machine. The diameter and depth of the anchoring holes should match the specifications of the anchor 5. Pre-assemble the sleeve 501 and the screw 502. Insert the assembled sleeve 501 and screw 502 into the drilled anchoring holes. Use a screwdriver compatible with the screw 502 to rotate the screw 502. The rotation of the screw 502 controls the moving end 504 to move upward, which in turn moves the lower end of the bending section 503 upward. The bending part 505 expands outward, and the bending section 503 bends, while simultaneously squeezing the soil at the contact point with the slope protection until the anchoring requirements are met. After the screw 502 is rotated into place, insert the "U"-shaped connecting rod 506 into the hole and pass through the green carpet 2 to connect the two screws 502 at the overlap of the green carpet 2, thereby anchoring the adjacent green carpet 2.

[0048] It is important to note that after the greening blanket 2 is laid and anchored, the holes drilled during anchoring need to be filled. Concrete or soil stabilizer can be used for filling. Watering should be done in time to keep the soil moist, ensuring that the plant seeds can germinate and grow successfully. The growth of the slope vegetation should be checked regularly to detect and prevent pests and diseases in a timely manner.

[0049] Before construction, the geological conditions of the slope 1 were assessed to ensure the safety and feasibility of the construction and to ensure that the quality of all materials met the requirements, especially the steel mesh 301, the reinforcing column 302, the conical end 303, the reinforcing plate 304, the soil stabilizer and the greening blanket 2, etc.

[0050] When using soil stabilizers, strictly follow the instructions in the product manual to ensure that the dosage and mixing uniformity of the stabilizer meet the requirements.

[0051] When installing anchor 5, ensure that sleeve 501 and screw 502 are assembled correctly. When rotating screw 502, apply force evenly and avoid excessive force or slow rotation.
