Vertical cement paste pouring working system

The utility model relates to the technical field of cement paste pouring, in particular to a vertical cement paste pouring working system which comprises a plunger rod shell and a plunger rod, and two pressure chamber shells are symmetrically installed on the left side and the right side of the plunger rod shell. The left side and the right side of the plunger rod are symmetrically, hermetically and slidably connected with the opposite sides of inner cavities of the two pressure chamber shells through two first sealing rings correspondingly, and the upper ends and the lower ends of the pressure chamber shells are detachably and fixedly connected with the pressure chamber upper shells and an output port in the top of the inlet pipe correspondingly. Second sealing rings are arranged between the pressure chamber outer shells and the pressure chamber upper outer shells and between the pressure chamber outer shells and an output port in the top of the inlet pipe, the top ends of the pressure chamber upper outer sh
