Abstract

PURPOSE: To facilitate drilling, by forming a new hole so that a hole previously drilled and the new hole can keep accurate relationship locations by mounting a guide plate to a drilling shaft positioned at an end portion, by using the plate as a guide shaft and by drilling holes by means of drilling shafts while inserting the shafts into the hole previously drilled.
CONSTITUTION: A plurality of drilling shafts 2 are installed in parallel in a row, and the drilling shaft 2 at an end portion is used as a guide shaft 4, to which a guide plate 3 for guide is mounted. The guide shaft 4 is inserted into a hole 5 beforehand drilled while earth and sand are drilled by means of the remaining drilling shafts 2, and a new hole 5a is drilled. Positional relationship between the hole previously drilled and the new hole 5a becomes accurate because holes are drilled by means of the drilling shaft 2 while the guide shaft 4 with the guide plate 3 enters into the hole 5 beforehand drilled at that time. Circular pillar holes are continuously formed by successively drilling holes with the hole 5 in the same manner.
