[0002] The safety guardrails used on highway bridges are mainly used to prevent vehicles from accidentally running off the bridge, to ensure driving safety, and to ensure smooth and safe road traffic.

[0003] However, the following problems may occur during actual use:

[0004] If the safety guardrail blocks the natural drainage path on the bridge and the accumulated water cannot be removed in time, it will cause water accumulation. The accumulated water will not only damage the bridge structure, but also increase driving risks and make it easy for slip accidents to occur.

[0005] Furthermore, if the accumulated water is blocked by the safety guardrail and cannot be discharged in time, it will inevitably accumulate at the bottom of the safety guardrail for a long time, and then corrode the bottom of the safety guardrail, causing damage to the safety guardrail or even collapse.

[0006] To sum up, how to solve the problem of water accumulation caused by safety guardrail obstruction is a technical problem that needs to be solved. Utility Model Content

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A safety guardrail for a highway bridge, comprising a railing, a base located at the lower end of the railing and a mounting frame located at the front end of the base, wherein the lower end of the railing is fixedly connected to the upper end surface of the base, and the front end of the base is fixedly connected to the mounting frame;

[0009] The front end surface of the base is provided with a V-shaped surface, a drainage channel is opened in the middle of the front surface of the V-shaped surface, and the inner surface of the drainage channel is coated with an anti-corrosion layer;

[0010] A filter is installed inside the installation frame.

[0011] Preferably, two sides of the base are fixedly connected with fixing seats.

[0012] Preferably, the V-shaped surface and the base are configured as an integrally formed structure.

[0013] Preferably, the interior of the mounting frame is fixedly connected to the filter screen.

[0014] Preferably, a T-shaped steel element is placed on the upper end surface of the conveyor belt.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model discloses a safety guardrail for a highway bridge. When it is used, when water accumulates on the highway bridge due to rain, the water will flow to the base. At this time, leaves and impurities will first be filtered by the filter net inside the installation frame, thereby preventing the drainage channel from being blocked by impurities or leaves. When the accumulated water flows into the surface of the V-shaped surface, it will flow to the drainage channel due to the inclination, and finally be discharged from the highway through the drainage channel, thereby preventing accidents caused by water accumulation on the highway bridge. An anti-corrosion layer is provided on the inner surface of the drainage channel. The anti-corrosion layer is specifically an epoxy anti-corrosion coating. The epoxy anti-corrosion coating is a coating with epoxy resin as the main component. It is coated on the inner surface of the drainage channel by painting to form a hard, corrosion-resistant protective layer, which can effectively prevent the accumulated water from corroding the drainage channel. By providing the V-shaped surface and the drainage channel, it can be avoided that the accumulated water accumulates at the base for a long time, affecting the stability of the base, thereby increasing the overall applicability.
