Description

Technical Field

[0001] This utility model belongs to the field of slope protection technology, specifically relating to a new type of slope support net. Background Technology

[0002] In recent years, with the rapid development of highway, railway, foundation pit, and open-pit mine construction in my country, geotechnical anchoring technology has ushered in unprecedented development opportunities and achieved rapid progress. As a traditional and effective technical means in the field of geotechnical slope treatment, anchoring technology has been increasingly widely used and recognized in engineering practice due to its multiple advantages, including ingenious structural design, simple construction operation, economical cost, and excellent performance. Integrating anchoring technology into slope engineering can not only leverage and enhance the strength characteristics and self-stabilizing capacity of the geotechnical mass, effectively improving its unfavorable stress distribution and thus significantly enhancing slope stability, but also significantly reduce the volume and self-weight of the structure, thereby achieving precise and effective control over the deformation of the slope geotechnical mass. With its excellent controllability, measurability, and high reliability, geotechnical anchoring technology has become one of the most economical and effective methods for improving slope stability and solving complex slope problems, playing an irreplaceable and important role in many fields such as transportation, water conservancy and hydropower, mining, and urban infrastructure construction in my country.

[0003] However, it is worth considering that there are still some problems that need to be solved in the current slope anchoring device technology. First, once the power part and the fixing part are connected, they are difficult to recycle, which undoubtedly increases the cost of use. Second, some anchor nets still have certain limitations in terms of fixing. The gaps between the anchor nets are relatively large, and the blocking effect on small rocks and soils is not ideal, and the protective performance needs to be improved. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a new type of slope protection net.

[0005] The technical solution of this utility model is: a novel slope protection net, comprising an anchoring device and a flexible wire. The anchoring device includes a power rod and a positioning cylinder. A limiting plate is fixedly connected to the top of the power rod. A connecting block is provided above the limiting plate, and a through power hole is provided on the connecting block. A spiral blade is provided below the power rod. A positioning cylinder is provided below the limiting plate, and the radius of the limiting plate is larger than the radius of the positioning cylinder. The positioning cylinder is movably connected to the power rod.

[0006] Furthermore, a number of fixing components are provided at equal intervals along the axis of the power rod, and the fixing components are disposed between the limiting plate and the spiral blade.

[0007] Furthermore, the fixing component includes fixing rods equidistantly arranged along the center of the power rod, the fixing rods being fixedly connected to the power rod; the inner wall of the positioning cylinder is provided with a groove corresponding to the fixing rod, the groove being an elongated groove.

[0008] Furthermore, the power rod has a drill bit located below the helical blades.

[0009] Furthermore, a hexagonal fixing plate is fixedly connected above the positioning cylinder, and each of the six corners of the hexagonal fixing plate is provided with a hollow anchor bolt hole.

[0010] Furthermore, the hexagonal fixing plate has a through hole in the middle corresponding to the positioning cylinder, and the edge of the through hole has a notch corresponding to the groove.

[0011] Furthermore, the hexagonal fixing plate has several fixing blocks evenly distributed along its edge. The fixing blocks are fixed to the hexagonal fixing plate by bolts, and the flexible line is connected to the hexagonal fixing plate through the fixing blocks.

[0012] The beneficial effects of this utility model are:

[0013] After the power rod drives the positioning cylinder into the slope, it can detach from the positioning cylinder and then be reused in other positioning cylinders, achieving a one-to-many working effect and saving costs. The six corners of the hexagonal fixing plate are provided with hollow anchor holes, and anchors can be added as needed to enhance the support effect. Flexible lines are used to connect the anchoring devices into a mesh structure. The mesh size can be adjusted according to the size of the gravel on the slope, improving the blocking effect on small pieces of rock and soil falling from the slope. The flexible lines are highly malleable and suitable for supporting slopes of various shapes. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] A novel slope protection net includes an anchoring device and a flexible wire 14. The anchoring device comprises a power rod 1 and a positioning cylinder 2. A limiting plate 3 is fixedly connected to the top of the power rod 1. A connecting block 4 is provided above the limiting plate 3, and a through power hole 5 is provided on the connecting block 4. A spiral blade 10 is provided below the power rod 1. The positioning cylinder 2 is located below the limiting plate 3, and the radius of the limiting plate 3 is larger than the radius of the positioning cylinder 2. The positioning cylinder 2 is movably connected to the power rod 1.

[0023] The drive device drives the power rod 1 through the power hole 5 on the connecting block 4. The power rod 1 drives the spiral blade 10 to rotate into the slope soil layer that needs protection. The positioning cylinder 2 is driven by the power rod 1 to rotate into the slope soil layer as well. The limiting plate 3 restricts the movement of the power rod 1 to prevent the power rod 1 from falling off and sinking into the positioning cylinder 2. The flexible line 14 connects the anchoring devices into a mesh structure. The mesh size can be adjusted according to the size of the gravel on the slope to improve the blocking effect of small soil and rocks falling from the slope. The flexible line 14 has strong plasticity and is suitable for supporting slopes of various shapes. The use of the positioning cylinder 2 as a fixing element makes the fixing effect better.

[0024] In a preferred embodiment of the present invention, a plurality of fixing components are provided at equal intervals along the axis of the power rod 1, and the fixing components are disposed between the limiting plate 3 and the spiral blade 10.

[0025] As a preferred embodiment of the present invention, the fixing component includes fixing rods 6 equidistantly arranged along the center of the power rod 1, the fixing rods 6 being fixedly connected to the power rod 1; the inner wall of the positioning cylinder 2 is provided with a groove 8 corresponding to the fixing rods 6, the groove 8 being an elongated groove.

[0026] In this embodiment, each fixing component has four fixing rods 6 equidistantly arranged along the center of the power rod 1. The inner wall of the positioning cylinder 2 has four grooves 8 corresponding to the fixing rods 6. When assembling the power rod 1 and the positioning cylinder 2, the positioning cylinder 2 is placed on the slope that needs protection. The power rod 1 enters from above the positioning cylinder 2, and the four fixing rods 6 are respectively inserted into the corresponding grooves 8. The fixing rods 6 and the grooves 8 cooperate to realize the movable connection between the power rod 1 and the positioning cylinder 2. When the slope needs to be protected, the power rod 1 rotates, and the positioning cylinder 2 rotates with the power rod 1 and screws into the soil layer. When the positioning cylinder 2 reaches a certain position, the power rod 1 can be pulled out vertically from the positioning cylinder 2.

[0027] In a preferred embodiment of this utility model, the power rod 1 is provided with a drill bit 11 below the spiral blade 10; the drill bit 11 makes drilling into the soil layer less strenuous.

[0028] In a preferred embodiment of this utility model, a hexagonal fixing plate 9 is fixedly connected above the positioning cylinder 2. Each of the six corners of the hexagonal fixing plate 9 is provided with a hollow anchor bolt hole 12. Anchor bolts can be inserted into the anchor bolt holes 12 to reinforce the anchoring device as needed.

[0029] As a preferred embodiment of the present invention, the hexagonal fixing plate 9 has a through hole in the middle corresponding to the positioning cylinder 2, and the edge of the through hole has a notch 7 corresponding to the groove 8; the notch 7 facilitates the fixing rod 6 to be pulled out from the groove 8, so that the power rod 1 is separated from the positioning cylinder 2.

[0030] In a preferred embodiment of the present invention, a plurality of fixing blocks 13 are evenly provided on the edge of the hexagonal fixing plate 9. The fixing blocks 13 are fixed on the hexagonal fixing plate 9 by bolts 15, and the flexible line 14 is connected to the hexagonal fixing plate 9 through the fixing blocks 13.

[0031] The flexible line 14 is set between the fixed block 13 and the hexagonal fixed plate 9. The fixed block 13 is fixed to the hexagonal fixed plate 9 by bolts 15, and the flexible line 14 can be installed and removed by bolts 15. If the flexible line 14 is only temporarily needed for soil protection, the flexible line 14 can be tied to the fixed block alone. The flexible line 14 connects the anchoring devices into a mesh structure. Depending on the size of the gravel on the slope, the flexible line 14 can be combined with several fixed blocks 13 on the hexagonal fixed plate 9 to form the required mesh size, thereby improving the blocking effect on the small gravel falling from the slope. The flexible line 14 can also block the small gravel exposed in the positioning cylinder 2 that is separated from the power rod 1.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, are all covered within the protection scope of this utility model.
