Pavement joint filling backing strip press-in device

A pavement joint filling backing strip press-in device comprises compaction wheels. The widths of the compaction wheels match with those of pavement expansion joints. The pavement joint filling backing strip press-in device is characterized in that the compaction wheels and travelling wheels are parallelly and coaxially connected onto axles by the aid of rolling bearings, the sizes of the travelling wheels are smaller than those of the compaction wheels, radius differences of the compaction wheels and the travelling wheels are equal to the depths of the backing strips embedded into joints to be filled, a hand push rod is connected to one end of each axle close to the respective travelling wheel, and the top end of the hand push rod is connected with a hand push handle. The pavement joint filling backing strip press-in device can conveniently press the backing strips into the joints to be filled evenly and rapidly, can ensure joint filling construction quality and facilitate operation, can remarkably improve c
