Tail gas degradation environment-friendly pavement structure

The utility model discloses a tail gas degradation environment-friendly pavement structure and relates to the field of environment-friendly pavements. The tail gas degradation environment-friendly pavement structure comprises a mounting column, a mounting support and an environment-friendly advertising board, the mounting support is fixedly clamped to the side face of the mounting column, and the environment-friendly advertising board is in threaded connection with the side face of the mounting support. According to the tail gas degradation environment-friendly pavement structure, by improving structures such as guideboards and billboards which can be seen everywhere on a road, the guideboards can have the function of absorbing and degrading automobile tail gas, and air passing through the tail gas degradation net cage is accelerated through the fan, so that the air containing the tail gas passes through the tail gas degradation net cage; the content of the tail gas in the air is reduced after absorption and
