| titleOfInvention | Propulsion method and pipe joint structure used for it |
| abstract | (57) [Summary] [PROBLEMS] To enable work of an inner pipe connection part from the outside of an outer pipe even after connecting an inner pipe. SOLUTION: In a starting pit S, an outer tube 1 of a double tube P in which an inner tube 2 is movably mounted inside an outer tube 1 through a packed layer a is ground W. Outer tube 1 of the double tube P to be subsequently pressed in And the end face of the outer pipe 1 of the future double pipe P is abutted, and the insertion port 2b of the future inner pipe 2 is inserted and connected to the receiving port 2a of the future inner pipe 2 to connect the front and rear double pipes. After joining the pipes, a horizontal pressing force is applied to the rear end face of the outer pipe 1 to propel it, and the joining and the propulsion are alternately repeated, and the inner pipe is moved horizontally while maintaining the insertion connection state with the movement of the outer pipe. This is a propulsion method that is integrally carried in the direction. Double pipe P, P A thrust transmitting segment 8 is interposed between the end faces of the outer pipes, and thrust is transmitted from the subsequent double pipes to the preceding double pipes P, P via this segment 8. At this time, after the connection of the inner pipes 2 and 2 is performed, the centering ring 10 and the segment 8 are fitted, the cover 11 is put on, and propulsion is performed. |
