The invention relates to a prefabricated concrete member multi-direction displacement adjustment device and a construction method thereof. The prefabricated concrete member multi-direction displacement adjustment device comprises a steel plate 1, a horizontal alignment device 4 and at least two lifting and moving devices 5; at least two steel bars 2 are arranged at the longitudinal side of the steel plate 1, and an outer threaded pipe 3 is arranged at the transverse side of the steel plate 1; the lifting and moving devices 5 are arranged below the steel plate 1 and are used for fine tuning ofthe vertical direction height and the horizontal direction position of two culverts; the horizontal alignment device 4 is movably connected with the outer threaded pipes 3 of any two movable fine tuning devices and is used for fine tuning of the horizontal direction distance of the two culverts. Quick and accurate assembly and alignment among sections of the culverts can be achieved, the installation and the construction are convenient, the fixation is firm, and repeated utilization is achieved.
