Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1-2 and Figure 5-6 This utility model provides a road and bridge engineering guardrail, including a guardrail frame 2 and two uprights 1. The guardrail frame 2 is located between the two uprights 1. The upper and lower parts of the rear side of the uprights 1 are respectively fixedly connected to a connecting ring 22 and a support ear 15. A support rod 3 is provided at the rear of the support ear 15, and a rotating shaft 16 is rotatably installed between the support ear 15 and the support rod 3. A U-shaped piece 17 is fixedly connected to the top rear side of the support rod 3, and an elastic net 4 is provided between the two support rods 3. A connecting ring 23 passes through the inside of the connecting ring 22. A pull plate 24 is fixedly connected to the front side of the connecting ring 23. A rotating shaft 18 is rotatably installed inside the U-shaped piece 17. A steel wire rope 5 is connected between the connecting ring 23 and the rotating shaft 18.

[0026] In this technical solution, the elastic net 4 between the two support rods 3 can not only catch garbage on the bridge and road, preventing it from falling directly into the river, but also catch items dropped by people. By pulling the connecting ring 23 through the pull plate 24, the connecting ring 23, the steel wire rope 5, the rotating shaft 18, and the U-shaped part 17 can drive the support rod 3 to rotate around the rotating shaft 16, rotating and pulling the elastic net 4 back, so that the caught items can be pulled back to the guardrail frame 2 for easy retrieval.

[0027] In some technical solutions, such as Figure 1 , Figure 3 and Figure 7 As shown, T-slots 9 are symmetrically provided on both sides of the upright 1, and bolts 10 are threadedly connected to both sides of the upper and lower front of the upright 1. T-shaped parts 11 are fixedly connected to both sides of the guardrail frame 2. The top of the T-slot 9 is open. The T-shaped part 11 is adapted to the T-slot 9, and threaded holes 25 matching the bolts 10 are provided on the T-shaped part 11.

[0028] In use, the guardrail frame 2 can be installed by inserting the T-shaped piece 11 into the T-slot 9 and then screwing the rear end of the bolt 10 into the threaded hole 25. This gives the guardrail a modular function, making installation and replacement more flexible.

[0029] In some technical solutions, such as Figure 1 , Figure 2 and Figure 4 As shown, a warning sign 6 is provided on the front side of the guardrail frame 2, and two slots 12 are provided on the upper front side of the guardrail frame 2. The top of the slot 12 is open. Two plugs 13 that match the slots 12 are fixedly connected to the rear of the warning sign 6. The plugs 13 are located inside the slots 12.

[0030] In use, the warning sign 6 can be installed by inserting the plug 13 into the slot 12, making it easy to replace the warning sign 6.

[0031] In some technical solutions, such as Figure 5 and Figure 8 As shown, several internally threaded sleeves 19 are fixedly connected to both sides of the top of the support rod 3. Several round holes 21 matching the internally threaded sleeves 19 are opened on both sides of the elastic net 4. The internally threaded sleeves 19 pass through the round holes 21, and a baffle 20 is provided on the top of the internally threaded sleeves 19. A threaded shaft 26 matching the internally threaded sleeves 19 is fixedly connected to the bottom of the baffle 20. The threaded shaft 26 is threadedly connected to the internally threaded sleeves 19.

[0032] In use, the threaded shaft 26 is unscrewed from the inside of the internal threaded sleeve 19 by rotating the baffle 20, the baffle 20 is removed, and the internal threaded sleeve 19 is passed through the round hole 21 to remove the elastic net 4, making it convenient to replace the elastic net 4.

[0033] In some technical solutions, such as Figure 1-2 As shown, several guardrail bars 7 are fixedly connected at equal intervals inside the guardrail frame 2.

[0034] When in use, multiple guardrails 7 serve as a barrier.

[0035] In some technical solutions, such as Figure 1 and Figure 5 As shown, a mounting plate 8 is fixedly connected to the bottom of the upright 1, and the mounting plate 8 has several mounting holes 14.

[0036] When in use, the pole 1 can be easily fixed to the road of the bridge through the mounting holes 14 on the mounting plate 8.

[0037] Working principle: During installation, the upright 1 is easily fixed to the road surface of the bridge through the mounting holes 14 on the mounting plate 8. The T-shaped piece 11 is inserted into the T-slot 9, and then the rear end of the bolt 10 is screwed into the threaded hole 25 to complete the installation of the guardrail frame 2. The elastic net 4 is then placed between the two support rods 3, so that the internal threaded sleeve 19 passes through the corresponding round hole 21. The threaded shaft 26 is then screwed into the internal threaded sleeve 19 to complete the installation. During use, the elastic net 4 can not only catch garbage on the bridge road to prevent it from falling directly into the river, but also catch items dropped by people. By pulling the connecting ring 23 through the pull plate 24, the connecting ring 23, the wire rope 5, the rotating shaft 18, and the U-shaped piece 17 can drive the support rod 3 to rotate around the rotating shaft 16, rotating and pulling back the elastic net 4 so that the caught items can be pulled back to the guardrail frame 2 for easy retrieval.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
