<p>PURPOSE:To provide a pipe burying method whereby the ground surface of burying a pipe can be placed in an almost flat condition while the pipe can be smoothly arranged to be buried in the ground without digging a ditch. CONSTITUTION:On both ends on a pipe arranging expected line, a hole of depth corresponding to the burying depth of a pipe P is respectively dug, to also previously form the pipe P of length longer than that between these holes, a drilling tool 61 is provided in the lower part or in the rearward of a knife 4 for generating a notch in the ground, an end of the pipe P is arranged behind the drilling tool 61, and by moving the knife 4 along the pipe arranging expected line by a moving means 1, the notch is generated in the ground by the knife 4. Simultaneously with the above, while drilling a hole equal to or larger than a diameter of the pipe P to a suitable depth in the ground by the drilling tool 61, the pipe P is towed, inserted and arranged in the ground, and the ground surface G2 of generating banking by underground passing the drilling tool is pressed by a pressing device so as to obtain almost flatness.</p> |
