Description

Technical Field

[0001] The invention relates to the field of isolation or other protection technologies of buildings, and in particular to a quick-install anti-corrosion guard plate for a road and bridge concrete guardrail. Background Art

[0002] Concrete guardrails are one of the most common road and bridge safety facilities. They are mainly used to separate traffic, protect pedestrians, and prevent vehicles from crossing the boundary. They are important isolation facilities in road and bridge traffic safety. In addition, concrete guardrails have good wear resistance and impact resistance and can withstand large external forces. Compared with metal guardrails, concrete is not easily corroded, has a longer service life, low maintenance costs, and reduces later management costs. Therefore, choosing the right type and design of concrete guardrails can effectively improve road safety and pedestrian protection, and is an indispensable part of modern transportation engineering.

[0003] At present, in order to ensure the passage of traffic after extreme weather such as snowfall and freezing rain, snow melting agents are used to accelerate the melting of ice and snow on roads and bridges, and snow removal equipment is used to remove ice and snow on roads. Therefore, the ice and snow containing snow melting agents shoveled to the concrete guardrail by the snow removal equipment will seriously affect the performance of the concrete and cause damage to the concrete guardrail. The usual preventive method is to cover the concrete guardrail with a baffle. However, conventional concrete guardrail baffles still have the following shortcomings:

[0004] Conventional baffles are mostly produced according to the structural dimensions of the New Jersey concrete guardrail, but other derivative dimensions of the New Jersey concrete guardrail are not applicable; there are still gaps at the edges of the baffles set in parallel, and the base of the concrete guardrail will still be corroded after the snow melts.
