The invention discloses a pumping hydraulic control system and concrete pumping equipment. Changing and repairing of a concrete piston are facilitated, and work efficiency of the concrete pumping equipment is improved. The pumping hydraulic control system comprises a concrete piston hydraulic control oil line and a buffering oil line, wherein the concrete piston hydraulic control oil line comprises two oil cylinders and a control oil line controlling operation of the two oil cylinders; each oil cylinder comprises a cylinder body, a limiting piston arranged in the cylinder body, a limiting piston rod, a pumping piston and a pumping piston rod; each cylinder body is divided into three cavities by the corresponding limiting piston and the corresponding pumping piston; the buffering oil line comprises a first control valve and communicating pipelines which correspond to the oil cylinders one by one; each communicating pipeline is connected with the first control valve; when in a first state, the first control valve controls a second cavity and a third cavity of each oil cylinder to communicate with each other; and when in a second state, the first control valve controls the second cavity and the third cavity of each oil cylinder to be isolated from each other.
