The invention discloses a roadbed concrete revetment pouring device which comprises a slope. A platform trolley A is arranged at the lower end of the slope. A platform trolley B is arranged at the upper end of the slope. A hydraulic lifting frame A is arranged on a body of the platform trolley A. A hydraulic lifting frame B is arranged on a body of the platform trolley B. The top end of the hydraulic lifting frame A and the top end of the hydraulic lifting frame B are in hinged connection with a pair of rod arms. A concrete hopper is arranged on the pair of rod arms. A fixed pulley is further arranged on the hydraulic lifting frame B. A motor is arranged on a body of the hydraulic lifting frame A. One side of the concrete hopper is connected with one end of a steel wire rope, and the other end of the steel wire rope is connected with a rotating shaft of the motor through the fixed pulley. A middle automatic hydraulic supporting frame is arranged at the lower end of the middle of each rod arm. According to the roadbed concrete revetment pouring device, the platform trolleys move leftwards and rightwards so as to complete transverse concrete pouring, the trolleys are controlled to move vertically so as to conduct vertical concrete pouring, and thus construction cost is lowered while the concrete pouring speed is increased.
