A method for raising road shoulder stone and curb stone after paving an overlay on a road surface and a slip forming machine used in the method. The method includes the steps of: S1) cleaning the surfaces of original road shoulder stone and curb stone; S2) determining the sizes, distances and number of planting nails, wherein the lengths of the planting nails is not less than one time and not more than two times of the thickness of the overlay; S3) according to determined positions, planting nails into the original road shoulder stone and curb stone; and S4) pouring raising concrete. The slip forming machine includes a machine body and a vibrating portion arranged thereon. The vibrating portion includes a vibrating board, two side boards, and a connecting rod connected between the two side boards. The thickness of the side boards is 15-20 mm and the thickness of the vibrating board is 10-15 mm. The method and the slip forming machine have good use effects, wherein the size of the slip forming machine can be adjusted according to road surface size, thereby raising the road shoulder stone and curb stone.
