The invention provides a sand pumping method, a sand pumping system and a sand pumping water suction head of the sand pumping system. The sand pumping water suction head comprises a main pipe and sand flushing pipes, and the sand flushing pipes are arranged in the main pipe in the axial direction of the main pipe. The upper ends of the sand pumping pipes penetrate through mounting holes in the main pipe and then protrude out of the main pipe. The sand pumping water suction head comprises a plurality of sand flushing pipes. By means of the sand pumping water suction head, water flow in the main pipe can flow smoothly, and the problem that the sand layer is too thick, and sand pumping cannot be conducted is solved. The sand pumping method, the sand pumping system and the sand pumping water suction head have the advantages of being simple in structure, low in cost and good in sand pumping effect.
