Abstract
The invention provides a pipe burying method by which a diameter of a pilot hole can be efficiently and reliably enlarged depending on various types of soil and a burying operation of a buried pipe is made stable. The method involves preparing various types of platy members, selecting a platy member suitable for a soil type from among the various types of platy members on the basis of a soil type search of a burying place, and attaching the selected platy member to a reamer main body, thereby forming a reamer suitable for the soil type. The method further involves annexing this reamer at a front end of a rod in a pilot hole, and pulling out this rod from the pilot hole while rotating the reamer together with the rotation of the rod, thereby burying a buried pipe to be connected to the reamer in the earth.
