The invention discloses a road barrier concrete pouring longitudinal steel bar intermittent sealing device. The device mainly comprises sealing liquid bags, liquid bag seats, a hydraulic pipe, a liquid storage barrel, a double-acting hydraulic cylinder and a fixed part. The sealing liquid bag is arranged in the liquid bag seat. Longitudinal steel bars are sleeved with the sealing liquid bags. The liquid storage barrel communicates with the sealing liquid bags through the hydraulic pipe. The liquid storage barrel is connected with the double-acting hydraulic cylinder. The hydraulic pressure in the liquid storage barrel is controlled through the double-acting hydraulic cylinder. The liquid storage barrel and the double-acting hydraulic cylinder are mounted on the fixed part. The intermittent sealing device provided by the invention is designed for longitudinal steel bars going into a concrete pouring cavity during road barrier concrete three-dimensional continuous construction. When the longitudinal steel bars
