Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and more specifically, to a base fixing structure for a large-slope curved slope. Background Technology

[0002] Steep curved slopes are common in natural environments and engineering construction. Due to their steep slopes and irregular surfaces, these slopes pose a significant risk of landslides and collapses, which can threaten the safety of the surrounding environment and facilities. The treatment of steep curved slopes is very important, as it not only serves a greening purpose, but also plays a crucial role in the maintenance of the roadbed.

[0003] Existing slope treatment methods are not specifically designed for steep slopes. If existing slope treatment methods are used, retaining walls are not well adapted to steep curved surfaces and cannot closely fit the curved shape of the slope. Under large slope loads, problems such as wall cracking and slippage are likely to occur, resulting in the inability to guarantee the stability and safety of the slope fixing structure.

[0004] A search revealed that Chinese patent CN205776270U discloses a fixing structure for steep slopes. In this structure, the grid is constructed from welded aluminum profiles, allowing for convenient and quick installation. First, polyester short-fiber cloth is laid on the slope surface through an adhesive layer. Then, a set of anti-slip baffles is fixed and evenly spaced on the polyester short-fiber cloth. A set of J-shaped anchor nails anchors the grid to the slope surface. A set of slots at the bottom of the grid engages with the anti-slip baffles to prevent slippage. Soil is filled into the inner grooves of the grid, and then a set of reinforcing steel bars is inserted for overall reinforcement. Finally, vegetation is planted on the filled soil. This method effectively prevents landslides and provides green coverage. The fixed grid modular construction achieves a high level of efficiency and provides excellent slope protection.

[0005] However, in actual use, this structure only uses one set of J-type anchor nails to anchor the grid body to the slope of the civil engineering. Due to the large slope angle, the component of gravity on the grid body and the soil and vegetation on it along the slope direction increases significantly. The J-type anchor nails need to withstand a greater tensile force that slides down the slope, resulting in insufficient anchoring force and causing the grid body to tend to slide down. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a base fixing structure for a large-slope curved surface to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A base fixing structure for a steep curved slope includes a slope soil layer, an anchor rod is installed inside the slope soil layer, one end of the anchor rod is set as the anchoring end, the other end of the anchor rod is set as the exposed end, and a reinforcement mechanism is provided on one side of the anchor rod.

[0009] The reinforcement mechanism includes multiple enlarged heads fixedly installed outside the anchor rod. Multiple geocells are provided on one side of the slope soil layer. Multiple through holes are opened on the surface of the geocells. The through holes are connected to the anchor rod. Multiple connecting grooves and multiple connecting blocks are opened on the side of the geocells. The geocells are connected to each other by the connecting grooves and connecting blocks. Vegetation bags are installed inside the geocells. One end of the exposed end penetrates the slope soil layer and extends to the outside of the slope soil layer. The surface of the exposed end is provided with a threaded groove. A nut is connected to the external thread of the threaded groove.

[0010] By adopting the above technical solution: the anchor rod is equipped with an enlarged head to increase the contact area with the slope soil layer, improve the anchoring force, and stabilize the anchor rod in the soil layer. The geocell is initially fixed by cooperating with the anchor rod through the through hole. The connecting groove and connecting block can be spliced ​​into a whole to provide space for the planting bag. The exposed end of the anchor rod is equipped with a threaded groove and a nut to firmly connect the geocell and other components, thereby enhancing the stability of the slope structure.

[0011] As a further description of the above technical solution: A connecting mechanism is provided on one side of the geocell, the connecting mechanism including a steel mesh frame provided on one side of the geocell, the steel mesh frame being provided on one side of the anchor rod, the surface of the steel mesh frame having multiple fixing holes, the fixing holes being connected to the anchor rod, a reinforcing mesh being provided on one side of the steel mesh frame, the surface of the reinforcing mesh having installation holes, the installation holes being connected to the anchor rod, and a plant fiber blanket being provided on one side of the reinforcing mesh.

[0012] By adopting the above technical solution: the steel mesh frame, through fixing holes and anchor rods, can work together with the geocell to enhance the overall stability of the structure, protect the geocell and the internal vegetation bags, and the reinforcing mesh is fitted onto the anchor rods through the installation holes, which increases the shear strength of the slope surface and prevents soil slippage and collapse. The plant fiber blanket is laid on one side of the reinforcing mesh, which can reduce the erosion of the slope by rainwater, maintain soil moisture, create a good environment for plant growth, and help the ecological restoration of the slope.

[0013] As a further description of the above technical solution: the surface of the plant fiber blanket is provided with multiple connecting grooves, and a U-shaped connecting block is inserted into the inside of the connecting groove. A threaded ground bolt is threadedly connected inside the U-shaped connecting block. One end of the threaded ground bolt passes through the plant fiber blanket and the reinforcing mesh in sequence and extends into the reinforcing mesh.

[0014] Multiple water interception channels are formed on the surface of the slope soil layer, and the cross-section of the water interception channels is set in a V shape.

[0015] By adopting the above technical solutions, we can effectively resist rainwater erosion, maintain soil moisture, provide a good environment for vegetation growth, promote slope ecological restoration, reduce water erosion of slope soil, further improve slope stability, and reduce the risk of geological disasters such as landslides.

[0016] The technical effects and advantages of this utility model are as follows:

The exposed end of the anchor rod is equipped with a threaded groove, which facilitates the subsequent connection of other components, improves the stability and reliability of the overall structure, and the geocells are initially fixed by cooperating with the anchor rod through the through holes, which is convenient and quick. Moreover, the geocells can be connected to form an integral slope coverage by using connecting grooves and connecting blocks, providing space for the placement of vegetation bags. This not only enhances the protection of the slope surface, but also creates conditions for slope greening, which is conducive to vegetation growth and achieves ecological restoration. At the same time, the material inside the vegetation bags can provide necessary support for plant growth.

[0018] By setting up a connection mechanism, compared with existing technologies, the steel mesh frame and reinforced mesh are fitted onto the anchor rods and tightened with nuts, firmly fixing the geocells, steel mesh frame, and reinforced mesh to the anchor rods, enhancing the overall stability of the slope. At the same time, it protects and restrains the geocells and vegetation bags, preventing their displacement or damage. The reinforced mesh increases the shear strength of the slope surface, effectively preventing soil slippage and collapse, and further improving the reliability of the slope structure. Moreover, the plant fiber blanket is fixed to the reinforced mesh through U-shaped connecting blocks and threaded bolts, which can reduce rainwater erosion, maintain soil moisture, create a good environment for plant seed germination and growth, and promote slope ecological restoration. The V-shaped water interception channel on the slope soil surface can intercept slope water flow, slow down the flow velocity, and allow the water to seep into the ground or be discharged in an orderly manner, further improving slope stability and effectively reducing the risk of geological disasters such as landslides.
