摘要： A concrete pumping structure and a control method thereof are disclosed. The concrete pumping structure includes a first pumping cylinder structure and a second pumping cylinder structure. Each pumping cylinder structure includes a delivery cylinder (1), a water tank (3) and a driving oil cylinder (7). The delivery cylinder (1) has a concrete piston assembly (2) inside, and during the pumping process, a piston rod (6) of the driving oil cylinder (7) drives the concrete piston assembly (2) to reciprocate in the delivery cylinder (1), and the water tank (3) is positioned between the delivery cylinder (1) and the driving oil cylinder (7). The concrete pumping structure also includes a concrete return hydraulic system, which controls the two driving oil cylinders (7) and drives the two concrete piston assemblies (2) to return back to the water tank (3) during returning the concrete.
