Concrete pavement hardness detection device

The utility model relates to the technical field of concrete pavement detection, in particular to a concrete pavement hardness detection device, and solves the problem that the efficiency and the accuracy of a concrete pavement hardness detection device in the prior art need to be improved. A concrete pavement hardness detection device comprises a U-shaped frame, an air cylinder is installed at the top of the U-shaped frame, a sliding plate is installed at the extending end of the bottom of the air cylinder, and two sets of pressure meters are symmetrically installed on the U-shaped frame. According to the utility model, the plurality of detection points are arranged at the horizontal position of the concrete pavement, the detection values are averaged by using the two pressure meters in a manner of carrying out on-site non-destructive hardness detection on the detection points, and the positioning lines are attached to the horizontal plate by using upward bulges near the concrete detection points, so that th
