Provided is a pipe supporting device for supporting an inner pipe constructed inside an outer pipe such as a press fitting pipe (propulsion pipe) or other casings. The pipe supporting device according to the present invention comprises: one or more device body parts mounted on the inner pipe inside the outer pipe; and pipe supporting units arranged on the device body parts. The pipe supporting units are composed of one or both of block-type supporting units and roller-type supporting units detachably attached to the body of the device body parts. According to the present invention, the pipe materials of the inner pipe constructed inside the outer pipe, such as the press fitting pipe press-fitted on the ground or the casings constructed other ways, are properly positioned at the center or desired positions of the outer pipe so that the inner pipe can be continuously constructed to improve the constructability of the outer pipe. Also, the pipe supporting device easily moves inside the outer pipe when the inner pipe is inserted in the outer pipe, and adjusts the height thereof corresponding to the inner diameter of the outer pipe. |
