A steel jacking pipe comprises a steel jacking pipe body and multiple supporting pieces arranged in a pipeline of the steel jacking pipe body at preset intervals. Each supporting piece comprises an annular stiffening rib fixedly connected with the steel jacking pipe body, two parallel first jacking shores and two parallel second jacking shores perpendicular to the first jacking shores, wherein the outer wall of each annular stiffening rib is attached to the inner wall of the steel jacking pipe body, the two ends of each first jacking shore are fixed to the inner wall of the corresponding annular stiffening rib, and the two ends of each second jacking shore are fixed to the inner wall of the corresponding annular stiffening rib and fixed to the two ends of the corresponding first jacking shore. According to the scheme, the annular stiffening ribs are arranged in the steel jacking pipe, the first jacking shores and the second jacking shores are arranged in the annular stiffening ribs to prevent radial deformation of the steel jacking pipe, force which is originally applied to the steel jacking pipe body is shared, and therefore force borne by the steel jacking pipe body is reduced, and the cross section of the steel jacking pipe body is prevented from deforming.
