Zusammenfassung:	PROBLEM TO BE SOLVED: To effectively prevent damage of a pipe part in an assumed region accompanying with displacement of the ground even when a pipe is buried over the assumed region where it is assumed that there is possibility of action of shearing force in the radial direction of the pipe in accordance with the displacement of the ground. SOLUTION: In this pipe burying construction method, the pipe C is buried over the assumed region E where it is assumed that there is possibility of action of shearing force in the radial direction of the pipe in accordance with the displacement of the ground and the whole periphery or substantially whole periphery of the pipe part (pipe part in the assumed region) 1 to be buried in the assumed region is covered with a cushioning material 2 whose spring constant in the radial direction of the pipe is smaller than spring constant of the ground in its assumed region to bury the pipe.
