PROBLEM TO BE SOLVED: To provide a method for carrying a long hollow pipe into an adit tunnel and a method for laying a pipe in the adit tunnel by a crane increasing safety while reducing work man-hour and achieving efficiency more than conventional methods.;SOLUTION: In this method for carrying the long hollow pipe into the adit tunnel, a guide wire 2 is stretched in the vertical direction on a wall face on an advance rigid pit A side opposing to an opening part of the adit tunnel B, a pulling-in carrier 4 movable into the adit tunnel B from the vicinity of a lower end of the guide wire 2 is arranged, the long hollow pipe 5 is vertically lowered into an advance rigid pit A while a suspension wire CR1 is connected with the long hollow pipe 5 fixing a lower part pipe suspension device 51 temporarily on one end side and fixing an upper part pipe suspension device 52 temporarily on the other end side, and then the pulling-in carrier 4 is moved into the adit tunnel B while the lower part pipe suspension device 51 is connected with the pulling-in carrier 4 to lay the long hollow pipe 5 horizontally.;COPYRIGHT: (C)2005,JPO&NCIPI
