PROBLEM TO BE SOLVED: To provide a pipe body support device for preventing floating and nose-down of a boring machine and a propulsion pipe inside a starting vertical shaft during propulsion construction.SOLUTION: The pipe body support device comprises: a propulsion base 5 for which a plurality of crossties 7 are fixed perpendicular to a propulsion direction at a bottom part of a ruler extended in the propulsion direction and provided on both side faces on the lower part of the boring machine and a propulsion pipe 10 in order to keep the center and level of the boring machine and the propulsion pipe 10 inside the starting vertical shaft; a fixed frame 1 for which an upper transverse beam 2 and left and right support columns 3 are assembled in a parallel cross shape so as to surround the boring machine and the propulsion pipe 10 in the propulsion direction at the back of a starting portal wall; a pressing metal fitting 8 equipped so as to be abutted to an outer surface of the boring machine and the propulsion pipe 10 at the lower part of the transverse beam 2 of the fixed frame 1; and an adjusting metal fitting 4 provided in the middle of the left and right support columns 3 of the fixed frame 1. The fixed frame 1 is fixed to the propulsion base 5 or base plate concrete of a vertical shaft, and is installed on at least one part. |
