Description

Technical Field

[0001] This utility model relates to the technical field of slope protection mechanisms, and in particular to a prefabricated, assembled, vegetation-concrete arched slope protection component. Background Technology

[0002] In the field of civil engineering, slope protection is an important part of ensuring project safety and the ecological environment. Especially in the construction of roads, water conservancy, and mines, slope instability and soil erosion can easily lead to safety hazards. Therefore, it is necessary to use effective slope protection structures for reinforcement.

[0003] Traditional slope protection methods often involve on-site pouring of concrete or masonry, which suffer from long construction periods, large on-site workloads, and significant susceptibility to weather and terrain variations. Furthermore, standardized production is difficult to achieve, and quality control is challenging. Simultaneously, traditional slope protection structures often overemphasize engineering performance while neglecting ecological compatibility, easily leading to vegetation damage on the slope surface, exacerbating ecological imbalance, and hindering soil and water conservation. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated, assembled, vegetation-supported concrete arched slope protection component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a slope protection body set on the slope body. The slope protection body contains several planted concrete slabs. The slope protection body is composed of several bottom components, several middle components and several top components spliced ​​together by high-strength bolts. Each bottom component, middle component and top component is fixed to the slope body by an anti-pull-out anchor assembly.

[0006] As a preferred embodiment of this utility model, the bottom component includes a third arched member, a third through groove is provided in the middle of the third arched member, a second connecting plate is provided on the top of the third arched member, a second triangular splicing plate is provided on the top of the second connecting plate, and bolt fixing holes are symmetrically provided on the bottom plates on both sides of the third arched member.

[0007] As a preferred embodiment of this utility model, the central component includes a second arched member, a second through groove is provided in the middle of the second arched member, a connecting plate is provided at the top of the second arched member, a triangular splicing plate is provided at the top of the connecting plate, and second triangular splicing grooves are symmetrically provided at the bottom of both sides of the second arched member.

[0008] As a preferred embodiment of the present invention, the top component includes a first arched member, the first arched member having a first through groove in the middle, and the bottom sides of the first arched member having symmetrically formed first triangular splicing grooves.

[0009] As a preferred embodiment of this utility model, the first triangular splicing groove, the second triangular splicing groove, the first triangular splicing plate, and the second triangular splicing plate are all provided with several bolt connection holes.

[0010] As a preferred embodiment of this utility model, the front sides of the first arched member, the second arched member, and the third arched member are all provided with guide arc plates, and the front sides of the first connecting plate and the second connecting plate are symmetrically provided with guide plates.

[0011] As a preferred embodiment of this utility model, several of the anti-pull-out anchor bolt assemblies are respectively disposed in several first through-pull grooves, several second through-pull grooves, and several third through-pull grooves. Each anti-pull-out anchor bolt assembly includes a cone head, a pull rod is disposed on the back of the cone head, several positioning anti-pull-out wheels are disposed on the pull rod, a screw is disposed at the tail of the pull rod, a pull plate is sleeved on the screw, a nut is threaded on the screw, the nut abuts against the back of the pull plate, and a steel pipe sleeve is also disposed on the outside of the pull rod.

[0012] As a preferred embodiment of this utility model, a geogrid is provided at the bottom of the vegetated concrete slab, a grid is provided on the geogrid, a vegetated concrete skeleton is provided on the geogrid, a vegetated base layer is laid on the vegetated concrete skeleton, and a grass seed development layer is laid on the vegetated base layer.

[0013] As a preferred embodiment of this utility model, water-blocking blocks are provided in the first through-pull groove, the second through-pull groove and the third through-pull groove.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This utility model improves construction efficiency and maintenance convenience through a prefabricated structure. It uses prefabricated concrete arched components (bottom, middle, and top components) to form the main body of the slope protection. All components can be mass-produced in the factory, with a high degree of standardization, allowing for precise control of dimensions and quality. This avoids the impact of weather, site conditions, and other environmental factors on on-site concrete pouring. During construction, installation can be completed simply by fitting triangular splicing grooves and triangular splicing plates, fixing with bolts, and anchoring with anti-pull-out anchor components. The splicing method is simple and easy to understand, and the operation is convenient, greatly reducing on-site work time and significantly shortening the overall construction period. In addition, if components are damaged in a localized area of ​​the slope, the damaged bottom, middle, or top components can be disassembled and replaced individually without the need for complete rework. This results in low maintenance costs and high flexibility, making it particularly suitable for slope projects that require rapid repair.

[0015] This utility model's vegetated concrete slab achieves both ecological protection and stability enhancement. The vegetated concrete slab is a prefabricated, mature component, internally reinforced by geogrids and supported by a vegetated concrete framework. Combined with a vegetated base layer and a grass seed development layer, the grass seeds can be initially cultivated before leaving the factory. Assembled within the space formed by the arched framework, it harmonizes with the surrounding natural environment, enhancing the aesthetics of the slope protection structure. Furthermore, the grass seed development forms a vegetation cover layer, with the roots gradually penetrating the slope soil, tightly bonding the vegetated concrete slab with the slope soil to form a composite slope protection layer of vegetation-slab-soil. This effectively enhances the slope's surface erosion resistance, reduces direct rainwater erosion, and simultaneously, the vegetation roots hold the soil in place, further improving the overall stability of the slope. This achieves the dual effects of engineering protection and ecological greening.

[0016] This utility model adopts a flow-guiding structure to optimize drainage and adapt to special geological environments. The flow-guiding arc plates set on the front of the first, second, and third arched components can guide the water collected on the slope to both sides of the components. The symmetrical flow-guiding plates on the front of the connecting plate one and connecting plate two can further guide the water flow to the bottom of the slope, forming an organized drainage path. This design avoids rainwater silting up at the component splicing points or directly impacting the slope soil. It is especially suitable for loess areas with soft soil that is easily eroded by water flow. Through orderly drainage, it can reduce the softening of the slope soil by rainwater infiltration, reduce the risk of landslides and collapses caused by seepage, ensure the long-term stability of the slope protection structure, and extend its service life.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figure 1-13 As shown, the present invention proposes a prefabricated assembled vegetated concrete arched slope protection component, which includes a slope protection body 100 set on the slope body 9. Several vegetated concrete slabs 5 are set inside the slope protection body 100. The slope protection body 100 is spliced ​​from several bottom components 3, several middle components 2 and several top components 1. Each bottom component 3, middle component 2 and top component 1 is fixed to the slope body 9 by an anti-pull-out anchor assembly 4. The third arched member 30 of the bottom component 3 carries the triangular splicing plate 33 through the top connecting plate 32. The bottom of the second arched member 20 of the middle component 2 is provided with second triangular splicing grooves 22 on both sides. The triangular splicing plate 33 and the second triangular splicing groove 22 are adapted to each other. When splicing, the triangular splicing plate 33 is embedded in the second triangular splicing groove 22. After the pre-set bolt docking holes 6 of the two are aligned, they are fixed by high-strength bolts 91 to achieve longitudinal fitting connection. The top of the second arched member 20 of the lower middle component 2 is provided with a triangular splicing plate 24 through a connecting plate 23. The bottom of the second arched member 20 of the upper middle component 2 is provided with a second triangular splicing groove 22 on both sides. The triangular splicing plate 24 is fitted into the second triangular splicing groove 22. After the bolt butt holes 6 are aligned, they are fixed with high-strength bolts 91 to form a continuous splicing of the multi-layer middle component 2. The top component 1 has a first triangular splicing groove 12 at the bottom of both sides of the first arched part 10. The top of the second arched part 20 of the uppermost middle component 2 has a triangular splicing plate 24. The first triangular splicing groove 12 and the triangular splicing plate 24 are fitted together. After the bolt docking holes 6 are aligned, they are fixed with high-strength bolts 91 to complete the connection between the top and the middle. Bottom component 3, middle component 2, and top component 1 are respectively fitted onto the screw 43 of the pull rod assembly 4 through the third through-slot 31, the second through-slot 21, and the first through-slot 11. After the screw 43 at the tail of the pull rod 41 passes through the slot, the pull plate 44 is fitted on it in sequence and the nut 45 is tightened so that the pull plate 44 is tightly pressed against the bottom surface of the through-slot. The components are fixed to the slope body 9 by the pull rod assembly 4 (the cone head 40 is anchored into the soil and the pull rod 41 is bonded to the concrete). The vegetation concrete slab 5 is laid in the space formed by splicing the adjacent top component 1, middle component 2 and bottom component 3. The geogrid 50 at the bottom is attached to the inner side of the component. The area is divided by the grid 51. The vegetation concrete skeleton 52, vegetation base layer 53 and grass seed development layer 54 are stacked on the upper layer in sequence to form a vegetation structure that is compatible with the main body of the slope protection 100. The guide arc plates 7 on the front of the first arched component 10, the second arched component 20, and the third arched component 30, together with the guide plates 8 on both sides of the front of the connecting plate 1 23 and the connecting plate 2 32, form a continuous drainage path. The guide arc plates 7 guide the water flow on the slope to both sides, and the guide plates 8 further guide the water flow to the bottom of the slope to avoid the water flow impacting the connection parts of the components.

[0021] During the actual construction, the slope body 9 is first trimmed according to the design requirements to ensure that the slope surface is flat and the slope meets the standard. After the trimming is completed, the installation position of the pull-out anchor rod assembly 4 is marked on the slope body 9 according to the drawings. The hole is drilled with a drilling machine according to the mark. Then, the pull-out anchor rod assembly 4 with the steel pipe sleeve 46 is driven into the hole and concrete is poured into the hole. During the pouring process, the steel pipe sleeve 46 is gradually pulled out to make the concrete fully bond with the slope soil and tie rod 41. After the concrete solidifies, the pull-out anchor rod assembly 4 is firmly anchored. After the anchor bolts are fixed, install the slope protection components in layers: Install bottom component 3: hoist bottom component 3 to the lowest row of anti-pull-out anchor rod assembly 4, so that the screw 43 of the tie rod 41 passes through the third through groove 31, put the pull plate 44 on the screw 43 and tighten the nut 45 so that the pull plate 44 is firmly pressed against the bottom surface of the third through groove 31, and the bottom component 3 is fixed. Install the middle component 2: Hoist the middle component 2 to the corresponding anti-pull-out anchor assembly 4 in the same manner, and fix it with screws 43, pull plates 44, and nuts 45. At the same time, make the second triangular splicing groove 22 of the middle component 2 precisely fit into the second triangular splicing plate 33 of the bottom component 3, align the bolt docking holes 6 of the two and drive in high-strength bolts 91; if multiple middle components 2 are required, install them upwards in this manner, with the second triangular splicing groove 22 of the upper middle component 2 fitting and fixing with the first triangular splicing plate 24 of the lower layer. Install top component 1: hoist top component 1 to the uppermost anti-pull-out anchor rod assembly 4, and fix it with screw 43, pull plate 44, and nut 45, so that the first triangular splicing groove 12 is fitted into the triangular splicing plate 24 of the uppermost middle component 2, and then fix it with high-strength bolt 91 after aligning the bolt mating holes 6. After all components are installed, water-blocking blocks 90 are inserted into each bolt hole 6 to prevent rainwater from corroding the bolts. Finally, the vegetation concrete slabs 5 are laid in the space formed by the splicing of the components, ensuring that the geogrid 50 at the bottom fits the components, thus completing the construction of the entire slope protection device.
