PROBLEM TO BE SOLVED: To provide a building method of a soil cement columnar wall which has high execution efficiency and reduces execution cost. SOLUTION: The building method of the soil cement columnar wall builds the soil cement columnar wall by using a multiple type drilling device which has a plurality of augers and forms a basic element by rotating the augers. This method includes a step for building a preceding element in such a way that a distance between the center of one end of an existing basic element and the center of one end of the preceding element exceeds a distance between centers of both ends of the basic element and a step for building a following element in such a way that one end of the following element laps over the end of the basic element and the other end of the following element laps over the end of the preceding element. The soil cement columnar wall is built by continuously repeating the steps using the preceding element as the next basic element. COPYRIGHT: (C)2007,JPO&INPIT
