Protection rubber strip of groove rail flangeway

The invention relates to a protection rubber strip of a groove rail flangeway. The protection rubber strip comprises a rubber strip body, multiple parallel protrusions are arranged, in the length direction of the rubber strip, of the upper surface of the rubber strip body, multiple oblong holes and/or oval holes are perpendicularly formed inside the rubber strip body, fin sides are arranged on the two sides of the rubber strip body, and accumulated water flow guiding grooves are formed between the fin sides and the rubber strip body. According to the structure, the protection rubber strip of the groove rail flangeway can be used for all rail transit road sections involving groove rail laying, relieve steel rail flange abrasion and corrosion and improve traffic safety of non-motor vehicles on a public road surface, in this way, the service life of a steel rail is prolonged, the maintaining cost is lowered, and the frequency of traffic accidents is reduced.
