The invention discloses an engineering machinery one-way confluence hydraulic control system which comprises a hydraulic motor, and the hydraulic motor is in driving connection with a steering brake pump and a working pump at the same time. The steering brake pump is connected with a main oil way, and the working pump is connected with an auxiliary oil way. The main oil way and the auxiliary oil way are connected to a working device in parallel, and the main oil way is connected to the working device and a steering and braking system through a priority valve. A conducting oil way is connected between the main oil way and the auxiliary oil way, a third one-way valve is arranged on the conducting oil way, and the conducting oil way is conducted in the direction from the auxiliary oil way to the main oil way; and the conducting oil path is connected in front of the priority valve. The hydraulic system is suitable for a motor-driven double-pump hydraulic system, the main oil way preferentially supplies braking and steering, the auxiliary oil way serves as supplement, and the system pressure is guaranteed all the time.
