[0032] Reference Figures 1 to 5The preferred embodiment of the present utility model is a temporary protective fence for the width of the roadbed, comprising: two fence posts 10 for being inserted into the ground and arranged at intervals, the top of the fence posts 10 being provided with a lifting structure; a fence mesh 20, mounted on the two fence posts 10 and located between the two fence posts 10; a dense net 30, mounted on the fence mesh 20; a barbed wire roller cage 40, which is arranged on the top of the fence post 10 through the lifting structure and extends to cover the space above the fence mesh 20; an anti-overturning pile 50 for being inserted into the ground, which is arranged outside the plane where the two fence posts 10 are located, and is connected to a fence post 10 through an anti-overturning rod 60. When installing this protective fence, the fence posts 10 and the anti-overturning piles 50 can be inserted into the ground, and then the fence mesh 20 can be installed between the two fence posts 10, and the encryption net 30 can be installed on the fence mesh 20. Then, a barbed wire roller cage 40 is set on the top of the fence post 10 through a lifting structure, and the anti-overturning pile 50 is connected to the fence post 10 using the anti-overturning rod 60. This can effectively reduce the amount of foundation pit excavation and reduce damage to the original foundation surface. The installation process is simpler, effectively facilitates construction, improves construction efficiency, and is reusable, which can effectively reduce construction costs. In addition, the encryption net 30 installed in this protective fence can effectively prevent small animals from passing through, the barbed wire roller cage 40 can effectively prevent climbing over, and the anti-overturning pile 50 and the anti-overturning rod 60 can effectively improve the firmness of this protective fence, thereby effectively improving the protection effect.

[0033] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0034] In this embodiment, the lower part of the encryption net 30 is connected to the ground, and the upper part of the fence mesh 20 is connected to the barbed wire cage 40, which can further prevent crossing and climbing over, and improve the protection effect.

[0035] In this embodiment, the number of anti-overturning piles 50 is the same as the fence posts 10 and corresponds one to one. Each anti-overturning pile 50 is connected to its corresponding fence post 10 through an anti-overturning rod 60, which can effectively improve the stability of the protective fence, effectively prevent overturning, and be more reliable.

[0036] In this embodiment, the plane where the anti-overturning piles 50 and their corresponding fence posts 10 are located is perpendicular to the plane where the two fence posts 10 are located, which can provide good support for the fence posts 10 and further improve the firmness of the protective fence.

[0037] In this embodiment, the anti-overturning rod 60 is tilted downward from the fence post 10 toward the anti-overturning pile 50 , which helps to reduce the angle between the anti-overturning rod 60 and the external force it is subjected to, thereby helping to improve the load-bearing capacity of the anti-overturning rod 60 .

[0038] In this embodiment, a plurality of connection portions are spaced apart on the column body of the fence post 10, each of which is provided with a plurality of laterally protruding first connection fins 12, each of which is provided with a first connection hole 13; a second connection fin 21 is provided on the fence mesh 20 corresponding to each first connection fin 12, and a second connection hole is provided on the second connection fin 21; each first connection hole 13 is aligned with each second connection hole and is penetrated by a first bolt assembly 71 to mount the fence mesh 20 on the fence post 10, resulting in a simple and firm structure, easy assembly and disassembly, and easy to manufacture and disassemble. In other embodiments, the fence mesh 20 may also be connected by other commonly used methods such as screw connection. In this embodiment, first connection fins 12 are provided on opposite sides of the fence post 10, making it convenient to use multiple protective fences in series.

[0039] In this embodiment, a clamp 80 is sleeved on the fence post 10. The clamp 80 is elastic and semi-open, with a third connecting fin 81 extending from each side of the opening. Each third connecting fin 81 is provided with a third connecting hole 82. The anti-overturning rod 60 is provided with a first through hole, which is aligned with each third connecting hole 82 and is penetrated by a second bolt assembly 72 to connect the anti-overturning rod 60 to the clamp 80. The structure is simple and strong, and easy to assemble and disassemble. Moreover, because the upper and lower positions of the clamp 80 on the fence post 10 can be adjusted according to the situation, the requirements for the spacing accuracy between the fence post 10 and the anti-overturning pile 50 can be reduced, making construction more convenient. In other embodiments, the anti-overturning rod 60 can also be connected to the fence post 10 by other common connection methods such as screw connection, but is not limited to this.

[0040] In this embodiment, a fourth connecting fin 51 is provided on the anti-overturning pile 50, a fourth connecting hole is provided on the fourth connecting fin 51, and a second through hole is provided on the anti-overturning rod 60. The second through hole is aligned with the fourth connecting hole and is penetrated by a third bolt assembly 73 to connect the anti-overturning pile 50 with the anti-overturning rod 60. The structure is simple, the connection is firm, and it is easy to process, manufacture and disassemble.

[0041] In this embodiment, the densification net 30 is tied to the fence mesh 20 by steel wire, which is convenient for disassembly and assembly, has strong adaptability, and is easy to construct.

[0042] In this embodiment, the supporting structure is a V-shaped fork 11, which facilitates the processing and manufacturing of the fence post 10 and can also effectively position the barbed wire rolling cage 40. In other embodiments, the supporting structure can also be selected from other suitable shapes and structures, and is not limited to this.

[0043] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0044] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the scope of protection of the present invention.
