Description
Technical Field
[0001] The utility model relates to the technical field of high slope construction, in particular to a high slope protective enclosure. Background Art
[0002] With the rapid development of social economy, cars have become an indispensable means of transportation in human society. With the continuous increase in the number of vehicles, the existing highway network can no longer meet the growing traffic demand. Therefore, it has become extremely urgent to upgrade and transform the existing highways. In these renovation projects, widening the highway subgrade is the key, whether in the design or construction stage. When reconstructing and expanding the existing highways, it is necessary to ensure the normal operation of the highway, which requires protecting the existing road surface. This is not only to ensure smooth traffic but also to prevent possible soil accumulation or slope landslides during construction, which may affect the normal road surface. Therefore, providing effective protective devices is crucial for highway reconstruction and expansion.
[0003] However, in the current slope protection devices used for highway reconstruction and expansion, most protective measures only set enclosures on one side of the emergency lane and do not set corresponding protection measures at the slope position. Such a design often makes it difficult for the enclosures on the emergency lane side to withstand the impact of debris flow when large-scale landslides occur on the slope. In addition, in the existing technology, the enclosures on the emergency lane side mostly adopt a Z-shaped single-layer steel plate structure, which lacks the ability of buffering and energy absorption and is easily damaged after being impacted by large-volume falling rocks. Although there are some enclosures with a certain buffering ability on the market, these enclosures usually have a complex structure, resulting in high production, transportation costs and great construction difficulty, and need to be improved. Summary of the Utility Model
[0004] The problem to be solved by the utility model is to provide a high slope protective enclosure aiming at the above deficiencies in the prior art, which solves the problems of the existing high slope protective enclosures in dealing with large-scale landslides and impacts of large-volume falling rocks, and has the advantages of simple structure and good protection.
[0005] The above utility model purpose of the utility model is achieved through the following technical solutions:
[0006] A high-slope protective enclosure, comprising a pair of first steel supports, a plurality of Z-shaped supports arranged between the pair of first steel supports, a plurality of windbreak and dust suppression nets, a second steel support, a plurality of diagonal braces arranged on the second steel support, and a plurality of safety passive nets. The pair of first steel supports are respectively installed on one side of the emergency lane through embedded parts. The plurality of windbreak and dust suppression nets are respectively arranged on the first steel supports and between two adjacent Z-shaped supports. The second steel support and the plurality of diagonal braces are respectively installed on one side of the high slope through embedded parts. The plurality of safety passive nets are respectively arranged on the second steel support.
[0007] By adopting the above technical solution, a double-layer enclosure is formed by the first steel support, the Z-shaped support and the windbreak and dust suppression net, and a single-layer enclosure is formed by the second steel support, the diagonal brace and the safety protection net, thus forming a solid frame structure, which can effectively resist the impact force of slope landslide and falling rocks, ensuring the stability and safety of the enclosure. Among them, the setting of a plurality of windbreak and dust suppression nets can effectively reduce the erosion effect of wind on the slope, reduce dust flying, protect the environmental quality of the construction area, and at the same time is conducive to reducing the visual impact on passing vehicles. The setting of a plurality of safety passive nets can effectively intercept and fix loose soil and stone when a landslide or falling rocks occur on the slope, preventing them from further sliding onto the road below, ensuring the smoothness of the road and driving safety. In addition, the use of embedded parts and anchor installation methods simplifies the construction process, shortens the construction period, reduces the construction difficulty and cost. Since the enclosure structure of the present utility model is simple and the connection between components is firm, it is convenient for daily inspection and maintenance, ensuring the long-term stability and reliability of the enclosure. In summary, the high-slope protective enclosure of the present utility model not only has good protective performance, but also has a simple structure, convenient construction and easy maintenance, is suitable for slope protection in highway reconstruction and expansion projects, and has high practical value and promotion prospects.
[0008] The present utility model is further arranged as: further comprising a plurality of atomizing spray heads, and the atomizing spray heads are installed on the top of the first steel support in a manner that the spray direction is upward.
[0009] By adopting the above technical solution, the atomizing spray heads can spray out fine water mist, effectively reducing the dust particles in the air and reducing the dust pollution in the construction area, further improving the dust suppression effect of the enclosure. In addition, the setting of the atomizing spray heads also has a cooling effect, which can provide a relatively comfortable environment for construction workers under hot weather conditions, and at the same time helps to reduce the surface temperature of the enclosure and extend the service life of the enclosure materials.
[0010] The present utility model is further configured as follows: The first steel bracket includes a plurality of first I-beams arranged vertically, a plurality of first galvanized steel plates disposed on the first I-beams, and a plurality of first channel steels arranged horizontally. The two ends of each first channel steel are respectively installed on the first galvanized steel plates of two adjacent first I-beams through fasteners. The opposite sides of the windbreak and dust suppression net are respectively disposed on two adjacent first channel steels.
[0011] By adopting the above technical solution, the structure of the first steel bracket is more stable. The first I-beams, as the main load-bearing members, can bear a large load, and the setting of the first galvanized steel plates further improves the corrosion resistance of the bracket and extends its service life. The horizontal arrangement of the first channel steels not only provides a stable support for the windbreak and dust suppression net but also can effectively disperse the wind force and reduce the impact of the wind on the enclosure. The use of fasteners ensures a more secure connection between the components, facilitates installation and disassembly, and improves the construction efficiency. Among them, the fasteners are M12 through bolts for fixing to complete the connection between the first galvanized plate and the first channel steel.
[0012] The present utility model is further configured as follows: The Z-shaped bracket includes a pair of third I-beams arranged horizontally and a fourth I-beam inclined between the pair of third I-beams. The two ends of each third I-beam are respectively disposed on the first I-beams of two adjacent first steel brackets. The opposite sides of the windbreak and dust suppression net are respectively disposed on the third I-beams of two adjacent Z-shaped brackets.
[0013] By adopting the above technical solution, the design of the Z-shaped bracket makes the enclosure structure more stable. The third I-beams, as the basic support, can effectively disperse the impact force from the slope, and the inclined setting of the fourth I-beam further enhances the bending resistance of the bracket and improves the stability of the overall structure. At the same time, the setting of the Z-shaped bracket provides a more solid support for the windbreak and dust suppression net, ensuring the reliability of the enclosure under harsh weather conditions.
[0014] The present utility model is further configured as follows: The mesh holes of the windbreak and dust suppression net are regular hexagons.
[0015] By adopting the above technical solution, the regular hexagon mesh hole structure can effectively disperse and slow down the wind speed under the action of the wind force, thereby reducing the erosion of the wind on the slope. At the same time, the uniform distribution of the regular hexagon mesh holes can improve the tear resistance of the enclosure, ensuring the stability and durability of the enclosure under harsh weather conditions.
[0016] The present utility model is further configured as follows: the second steel bracket includes a plurality of second I-beams arranged vertically, a plurality of second galvanized steel plates disposed on the second I-beams, and a plurality of second channel steels arranged horizontally. The two ends of the second channel steel are respectively installed on the second galvanized steel plates of two adjacent second I-beams through fasteners, and the opposite sides of the safety passive net are respectively disposed on two adjacent second channel steels.
[0017] By adopting the above technical solution, the structural design of the second steel bracket further enhances the overall stability of the enclosure. The second I-beam, as the main load-bearing member, can bear a large load, and the setting of the second galvanized steel plate further improves the corrosion resistance of the bracket and extends its service life. The horizontal arrangement of the second channel steel not only provides a stable support for the safety passive net but also can effectively disperse the wind force and reduce the impact of the wind on the enclosure. The use of fasteners ensures a more firm connection between the components, facilitating installation and disassembly and improving the construction efficiency. Among them, the fasteners are fixed by M12 through bolts to complete the connection between the second galvanized plate and the second channel steel.
[0018] The present utility model is further configured as follows: the diagonal bracing bracket includes a fifth I-beam arranged horizontally and a sixth I-beam inclinedly disposed on the fifth I-beam. The ends of the fifth I-beam and the sixth I-beam are respectively disposed on the second I-beam.
[0019] By adopting the above technical solution, the design of the diagonal bracing bracket further enhances the stability of the enclosure structure. The fifth I-beam, as the basic support, can effectively disperse the impact force from the slope, and the inclined setting of the sixth I-beam further enhances the bending resistance of the bracket and improves the overall structural stability. At the same time, the setting of the diagonal bracing bracket provides a more solid support for the safety passive net, ensuring the reliability of the enclosure under harsh weather conditions.
[0020] The present utility model is further configured as follows: the mesh holes of the safety passive net are in an equilateral triangle shape.
[0021] By adopting the above technical solution, the equilateral triangle mesh hole structure can more effectively disperse the impact force when intercepting falling rocks and landslides, thereby improving the protection performance of the safety passive net. The geometric characteristics of the equilateral triangle enable each mesh hole to evenly transmit the force to the entire mesh surface when subjected to external forces, thus avoiding local stress concentration and enhancing the overall stability and durability of the mesh surface. In addition, the close arrangement of the equilateral triangle mesh holes can also effectively reduce the passage of soil and stone particles, further enhancing the protection effect of the enclosure on the slope.
[0022] In summary, the beneficial technical effects of the present utility model are as follows: The high-slope protective enclosure of the present utility model forms a double-layer enclosure through the first steel bracket, Z-shaped bracket and windbreak and dust suppression net, and forms a single-layer enclosure through the second steel bracket, diagonal brace bracket and safety protection net.

It is suitable for slope protection in highway reconstruction and expansion projects, and has high practical value and promotion prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the drawings and specific embodiments.
[0032] Refer to Figure 1, A high-slope protective fence disclosed by the present utility model includes a group of double-layer fences 1 and single-layer fences 2 arranged in groups. Among them, the double-layer fences 1 are arranged opposite to the emergency lane, and the single-layer fences 2 are arranged opposite to the high slope, thus forming a solid frame structure that can effectively resist the impact of slope landslides and falling rocks, ensuring the stability and safety of the overall fence.
[0033] Refer to Figure 4 , First of all, the double-layer fence 1 includes a pair of first steel supports 11, a plurality of Z-shaped supports 12 arranged between the pair of first steel supports 11, a plurality of windbreak and dust suppression nets 13, and a plurality of atomizing spray heads 14.

The structure of the first steel support 11 is more stable. The first I-beam 111, as the main load-bearing member, can bear a large load, and the setting of the first galvanized steel plate 112 further improves the corrosion resistance of the support and extends its service life; the horizontal arrangement of the first channel steel 113 not only provides a stable support for the windbreak and dust suppression net 13, but also can effectively disperse the wind force and reduce the impact of the wind on the fence; the use of fasteners ensures that the connection between each component is more firm, which is convenient for installation and disassembly, improving the construction efficiency.

Among them, both ends of the third I-beam 121 are respectively arranged on the first I-beams 111 of two adjacent first steel supports 11. The design of the Z-shaped support 12 makes the fence structure more stable. The third I-beam 121, as the basic support, can effectively disperse the impact force from the slope, and the inclined setting of the fourth I-beam 122 further enhances the bending resistance of the support and improves the stability of the overall structure; at the same time, the setting of the Z-shaped support 12 provides a more solid support for the windbreak and dust suppression net 13, ensuring the reliability of the fence under bad weather conditions.
[0036] Refer to Figure 2 , the mesh holes of the windbreak and dust suppression net 13 are regular hexagons. The opposite sides of some of the windbreak and dust suppression nets 13 are respectively arranged on two adjacent first channel steels 113, and the opposite sides of the remaining windbreak and dust suppression nets 13 are respectively arranged on the third I-beams 121 of two adjacent Z-shaped brackets 12. The regular hexagon mesh hole structure can effectively disperse and slow down the wind speed under the action of wind, thereby reducing the erosion of the wind on the slope; at the same time, the uniform distribution of the regular hexagon mesh holes can improve the tear resistance of the enclosure, ensuring the stability and durability of the enclosure under bad weather conditions.
[0037] Refer to Figure 7 , secondly, the single-layer enclosure 2 includes a second steel bracket 21, a plurality of diagonal braces 22 arranged on the second steel bracket 21, and a plurality of safety passive nets 23. Among them, the second steel bracket 21 and the plurality of diagonal braces 22 are respectively installed on one side of the high slope through embedded parts (not marked in the figure), and the plurality of safety passive nets 23 are respectively arranged on the second steel bracket 21.
[0038] Refer to Figure 5 and Figure 6 , the second steel bracket 21 includes a plurality of second I-beams 211 arranged vertically, a plurality of second galvanized steel plates 212 arranged on the second I-beams 211, and a plurality of second channel steels 213 arranged horizontally. The two ends of the second channel steel 213 are respectively installed on the second galvanized steel plates 212 of two adjacent second I-beams 211 through fasteners (not marked in the figure). The structural design of the second steel bracket 21 further enhances the overall stability of the enclosure. The second I-beam 211, as the main load-bearing member, can bear a large load, and the setting of the second galvanized steel plate 212 further improves the corrosion resistance of the bracket and extends its service life; the horizontal arrangement of the second channel steel 213 not only provides a stable support for the safety passive net 23, but also can effectively disperse the wind force and reduce the impact of the wind on the enclosure; the use of fasteners ensures that the connection between each component is more firm, which is convenient for installation and disassembly, and improves the construction efficiency. Among them, the fasteners are M12 through bolts for fixing to complete the connection between the second galvanized plate and the second channel steel 213.
[0039] Refer to Figure 7The diagonal brace bracket 22 includes a fifth I-beam 221 arranged horizontally, and a sixth I-beam 222 obliquely arranged on the fifth I-beam 221. The ends of the fifth I-beam 221 and the sixth I-beam 222 are respectively arranged on the second I-beam 211. The design of the diagonal brace bracket 22 further enhances the stability of the enclosure structure. The fifth I-beam 221, as the basic support, can effectively disperse the impact force from the slope, and the oblique setting of the sixth I-beam 222 further enhances the bending resistance of the bracket and improves the stability of the overall structure. At the same time, the setting of the diagonal brace bracket 22 provides a more solid support for the safety passive net 23, ensuring the reliability of the enclosure under severe weather conditions.
[0040] Reference Figure 6 The mesh of the safety passive net 23 is in the shape of an equilateral triangle, and the opposite sides of the safety passive net 23 are respectively arranged on two adjacent second channel steels 213. The equilateral triangle mesh structure can more effectively disperse the impact force when intercepting falling rocks and landslides, thereby improving the protective performance of the safety passive net 23. The geometric characteristics of the equilateral triangle enable each mesh to evenly transfer force to the entire mesh surface when subjected to external force, thereby avoiding local stress concentration and enhancing the overall stability and durability of the mesh surface. In addition, the close arrangement of the equilateral triangle mesh can also effectively reduce the passage of soil and stone particles, further improving the protective effect of the enclosure on the slope.

Among them, the setting of multiple windbreak and dust suppression nets 13 can effectively reduce the erosion of the wind on the slope, reduce dust flying, protect the environmental quality of the construction area, and at the same time is conducive to reducing the visual impact on passing vehicles. The setting of multiple safety passive nets 23 can effectively intercept and fix loose soil and stone when a landslide or falling rock occurs on the slope, preventing it from further sliding onto the road below, ensuring the smoothness of the road and driving safety. In addition, the use of embedded parts and anchor installation methods simplifies the construction process, shortens the construction period, reduces the construction difficulty and cost. Since the enclosure structure of the present utility model is simple and the connection between components is firm, it is convenient for daily inspection and maintenance, ensuring the long-term stability and reliability of the enclosure; at the same time, the atomizing sprinkler head 14 can spray fine water mist, effectively reducing the dust particles in the air and reducing the dust pollution in the construction area, further improving the dust suppression effect of the enclosure; in addition, the setting of the atomizing sprinkler head 14 also has a cooling effect, which can provide a relatively comfortable environment for construction workers under hot weather conditions, and at the same time helps to reduce the temperature of the enclosure surface and extend the service life of the enclosure materials. In summary, the high-slope protective enclosure of the present utility model not only has good protective performance, but also has a simple structure, convenient construction, and easy maintenance, and is suitable for slope protection in highway reconstruction and expansion projects, with high practical value and popularization prospects.
