Description

Technical Field

[0001] This utility model relates to the field of slope protection engineering technology, specifically to a composite slope protection structure of frame beams and vegetation concrete. Background Technology

[0002] In the field of slope protection engineering, traditional slope protection structures have many shortcomings and can no longer meet the actual needs of current engineering construction. Early methods using simple reinforced concrete frame beam structures, while possessing a certain mechanical strength and providing basic support for slopes, suffer from poor ecological benefits and cannot achieve vegetation restoration. While ordinary vegetated concrete slope protection structures have somewhat compensated for the ecological deficiencies of reinforced concrete frame beam structures, their mechanical properties are severely inadequate. When facing high slopes or slopes with complex geological conditions, they struggle to withstand large slope loads, easily leading to structural deformation and damage.

[0003] Furthermore, poor coordination between the anchoring system and the facing structure is also a common problem. In practical applications, the anchoring system cannot form an efficient working mechanism with the facing structure, resulting in insufficient overall seismic and anti-sliding performance. Especially under extreme conditions such as earthquakes and heavy rainfall, the problem of insufficient coordination between the two is further amplified, which may lead to disasters such as slope landslides and collapses.

[0004] In summary, the various shortcomings of traditional slope protection structures urgently necessitate the development of a new type of slope protection structure to meet the diverse requirements of engineering construction regarding safety, ecological sustainability, and structural synergy in slope protection.

[0007] (II) Technical Content

[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is: a composite slope protection structure of frame beams and vegetation concrete, comprising:

[0009] Support frame system: A rectangular grid structure composed of intersecting reinforced concrete beams;

[0010] Ecological surface protection system: a layer of vegetated concrete and surface vegetation filling the grid structure;

[0011] Anchoring system: includes prestressed anchor rods that are vertically inserted into the slope rock and soil and anchorages that connect the anchor rods to the reinforced concrete beams;

[0012] Drainage system: Consists of permeable pipes embedded in reinforced concrete beams;

[0013] The reinforced concrete beam forms a 30-50cm deep embedment groove on the slope surface. The vegetation concrete layer is flush with the top surface of the longitudinal and transverse beams and connected by reserved steel bars. The permeable pipe penetrates the reinforced concrete beam at an inclination angle of 5-10°.

[0014] Furthermore, the prestressed anchor bolts of the anchoring system are arranged with the lower end of the anchor bolt penetrating at least 4m into the stable soil and rock layer.

[0015] Furthermore, the permeable pipes of the drainage system are PVC corrugated pipes, and the spacing between adjacent permeable pipes is 1.5-2m.

[0016] Furthermore, the planted concrete layer is composed of aggregates with a particle size of 5-20 mm, sulfoaluminate cement, and plant fibers, with a porosity of 25-35%.

[0017] Furthermore, the surface vegetation includes a three-dimensional geonet and a mixed grass layer, with the three-dimensional geonet anchored to the vegetation concrete layer by U-shaped nails.

[0018] (III) Technical Effects

[0019] The advantages of this utility model compared with the prior art are as follows:

[0020] 1. Significant ecological benefits: By filling the grid structure composed of reinforced concrete beams with a layer of vegetated concrete and setting up surface vegetation, the vegetation restoration of the slope is achieved, which is conducive to soil and water conservation, environmental beautification and ecological balance maintenance.

[0021] 2. Enhanced mechanical properties: The support frame system is composed of intersecting reinforced concrete beams, which are connected to the vegetation concrete layer through pre-reserved steel bars. The two work together to effectively withstand large slope loads, thereby improving the stability and reliability of the protective structure.

[0022] 3. Good drainage performance: The permeable pipes embedded in the reinforced concrete beams are PVC corrugated pipes that penetrate the beams at a certain angle. The spacing between adjacent permeable pipes is reasonable, which can drain the water accumulated in the slope in time and avoid structural instability caused by water accumulation.

[0023] 4. Enhanced Synergy and Seismic and Anti-sliding Performance: The prestressed anchor rods of the anchoring system penetrate deep into the stable soil and rock layer and are connected to the reinforced concrete beam through anchorages. Working in synergy with the facing structure, the overall seismic and anti-sliding performance of the structure is greatly improved, ensuring slope safety under extreme working conditions.

[0035] Support frame system 1: Consists of a rectangular grid structure composed of intersecting reinforced concrete beams 101;

[0036] Ecological surface protection system 2: a vegetated concrete layer 201 and surface vegetation 202 filled within the grid structure. The vegetated concrete layer 201 is composed of aggregate with a particle size of 5-20mm, sulfoaluminate cement and plant fibers, with a porosity of 25-35%. The surface vegetation 202 includes a three-dimensional geonet 202a and a mixed grass layer 202b. The three-dimensional geonet 202a is anchored to the vegetated concrete layer 201 by U-shaped nails 202c.

[0037] Anchoring system 3: includes prestressed anchor rods 301 that are vertically inserted into the slope rock and soil and anchorages 302 that connect the anchor rods to the reinforced concrete beam 101. The prestressed anchor rods 301 of the anchoring system 3 are spaced apart and the lower end of the anchor rod penetrates into the stable rock and soil layer by no less than 4m.

[0038] Drainage system 4: consists of permeable pipes 401 embedded in reinforced concrete beam 101. The permeable pipes 401 of drainage system 4 are PVC corrugated pipes, and the spacing between adjacent permeable pipes is 1.5-2m.

[0039] The reinforced concrete beam 101 forms a 30-50cm deep embedment groove on the slope surface. The vegetation concrete layer 201 is flush with the top surface of the longitudinal and transverse beams and is connected by the reserved steel bars 203. The permeable pipe 401 penetrates the reinforced concrete beam 101 at an inclination angle of 5-10°.

[0040] The working principle of this utility model's composite slope protection structure of frame beam and vegetated concrete is as follows: The device provides foundation support through a support frame system 1, anchoring system 3 stabilizes the entire structure on the slope's rock and soil, ecological facing system 2 enables vegetation growth and slope protection, and drainage system 4 drains accumulated water to maintain structural stability. The synergistic effect of these systems enhances slope stability and promotes ecological restoration.

[0041] The working process of this utility model's composite slope protection structure of frame beams and vegetation concrete is as follows:

[0042] 1. Support frame construction: Intersecting reinforced concrete beams 101 are fixed to the slope surface to form a rectangular grid structure with embedded grooves inside, providing a support skeleton for the entire protective structure.

[0043] 2. Anchoring system installation: Insert the prestressed anchor rod 301 vertically into the slope soil and rock mass, ensuring that the lower end of the anchor rod penetrates into the stable soil and rock layer by no less than 4m. Then, connect the prestressed anchor rod 301 to the reinforced concrete beam 101 through the anchor 302, so that the entire support frame is tightly anchored to the slope soil and rock mass, thereby enhancing the structure's anti-sliding and seismic resistance.

[0044] 3. Ecological slope protection construction: The grid formed by the reinforced concrete beam 101 is filled with a vegetation concrete layer 201 composed of aggregate with a particle size of 5-20mm, sulfoaluminate cement and plant fiber, with a porosity of 25-35%. The vegetation concrete layer 201 is flush with the top surface of the longitudinal and transverse beams and is connected to the reinforced concrete beam 101 by the reserved steel bars 203. Then, a three-dimensional geonet 202a is laid on the surface of the vegetation concrete layer 201 and anchored with U-shaped nails 202c. Then, a mixed grass layer 202b is laid to promote vegetation growth and play a role in slope protection and ecological restoration.

[0045] 4. Drainage system setup: PVC corrugated pipes with an inclination angle of 5-10° and a spacing of 1.5-2m are pre-embedded in the reinforced concrete beam 101 as permeable pipes 401. When it rains or the slope seeps water, the accumulated water is discharged through the permeable pipes 401 to prevent water accumulation on the slope from causing structural instability.

[0046] 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.
