ことを特徴とした推力分散装置。 In a construction method in which a steel pipe is propelled by applying original thrust to the tip of the cutting edge, a soft duct provided to cover the steel pipe is tightly tied to the tip of the cutting edge, and the method is carried out by towing it or partially applying direct thrust to propel it and burying it. A steel pipe of a fixed length with an internal auger screw, an expansion ring attached to the steel pipe with ring-shaped fixtures at multiple locations on the outside of the steel pipe and installed inside the soft duct, and each expansion ring. It consists of a connecting pipe that supplies gas or liquid for expansion, and a soft duct that is approximately the same length as the steel pipe, covers the pipe body, and is supported by an expansion ring, and each soft duct is installed at multiple locations for each steel pipe. A thrust dispersion device characterized by dispersing the thrust force applied to a soft duct by uniform frictional force action.
