The invention discloses an instantaneous hydraulic hammering device and a testing system and method based on the instantaneous hydraulic hammering device. The instantaneous hydraulic hammering device comprises a nitrogen chamber, a hydraulic cylinder, a piston, an energy accumulator, a reversing valve, a piston rod, a push rod, a force hammer and a positioning base station. Wherein the piston is located in the hydraulic cylinder, the interior of the hydraulic cylinder is sequentially divided into a first cavity, a second cavity, a third cavity and a fourth cavity of the piston from top to bottom, the lower end of the piston is connected with the upper end of the piston rod, the lower end of the piston rod right faces the upper end of the force hammer, the lower end of the push rod is inserted into the hydraulic cylinder and then connected with the upper end of the piston, and the upper end of the push rod is inserted into the nitrogen chamber; an annular groove is formed in the middle of the piston, and the o
