The invention discloses a split type water jet propulsion inlet flow channel structure which is characterized in that the structure comprises a vertical plate, a base and a bent pipe flow channel, the vertical plate, the base and the bent pipe flow channel are three independently-machined components, the side face end of the vertical plate is connected with the side face end of the bent pipe flow channel, the bottom end of the bent pipe flow channel is connected with the top end of the base, and the top end of the bent pipe flow channel is connected with the top end of the base. The edge and the bottom end of the vertical plate are connected with the base. While the hydrodynamic performance of the inlet runner is guaranteed, casting defects can be remarkably reduced, the structural strength is improved, the machining process is simplified, the equipment requirement is lowered, the manufacturing period is shortened, and the safety, reliability and economical efficiency of the water-jet propeller are effectively improved.
