The invention relates to a waterpower self-excited oscillation jet flow vibratory pile sinking device and a pile sinking technology. A reinforced concrete pile body is a sheet pile, a square pile head and a hanging ring are arranged in the middle of the top of the reinforced concrete pile body, the reinforced concrete pile body is connected with a vibratory hammer part through a vibratory hammer connecting device, a jet flow pipe with a self-excited oscillation jet flow nozzle is arranged on the bottom of the sheet pile, the jet flow pipe is connected with a high pressure water pump group through a water pipe and rapid docking movable elbows, and the vibratory hammer part is connected with lifting equipment through an integrated lifting appliance. The waterpower self-excited oscillation jet flow vibratory pile sinking device and the pile sinking technology have the advantages that construction technologies of different strata can be resolved, construction efficiency can be improved greatly at the same time, construction quality is guaranteed, drawbacks and defects exist in the prior art are overcome or avoided, the problems of hard clay strata pile sinking speed and breakdown of underground obstacles are resolved, the purpose that undisturbed soil on two 2-meter-long sides of the bottom of the pile body in a pile sinking process is not damaged is achieved, the two sides of the pile body are filled with sand to enable disturbed soil on the two sides of the pile body to be replaced by silver sand, and fast consolidation is achieved.
