PURPOSE: A Steel Pipe jacking method using a steel lining is provided to prevent a deformation caused by the soil inside of a jacking pipe pressured into underground. CONSTITUTION: A Steel Pipe jacking method using a steel lining is as follows. A steel lining(30) is installed in the inner periphery of an end part of a cutting head(10) and a jacking pipe. The cutting head is pressured into underground by using a hydraulic cylinder(25). The jacking pipe is arranged so that an end part of the jacking pipe where the steel lining is installed and a front-end of the jacking pipe are contacted. The cutting head and the front-end of the jacking pipe are connected by welding. The end part of the jacking pipe is pressurized by using the hydraulic cylinder so that the cutting head and jacking pipe are pressured into underground. |
