The present invention enables each segment, in which two center through-paths and two end through-paths are formed, to be sequentially and adjacently arranged at each column in a vertical direction, wherein: horizontal segments at four columns are set as one unit such that strands are inserted, strained, and settled therein; only one strand is settled in each segment such that only the corresponding segment is settled and fixed; the segments, by the remaining three strands, located at the other columns are sequentially settled and fixed in the same manner as above via through-paths, thereby forming a foundation reaction wall through which all the four strands pass, and at the same time, segments at the other columns are also sequentially and easily settled and fixed by the remaining three strands with respect to structurally-stabilized foundation reaction wall; and the foundation reaction wall of the segments is formed and the other columns in accordance with the foundation reaction wall are sequentially settled and fixed together with a drilling operation by repeating the above steps. Thus, through said features, the invention allows the segments to be assembled in an efficient and economical manner. |
