If the depth of the excavation hole is deeper than the length of the preceding file (b) and the trailing file (c), the preceding file (b) and the trailing file (c) When a file connecting device of a flange type is formed at the upper and lower ends of the upper and lower files, the file connecting device is fastened with a bolt or the like to connect the upper and lower files, and when the file connecting device is not constituted, Connect.

The connecting portions (b-1, c-1) are each provided on the right and left sides of the leading file (b) and the trailing file (c) and have diameters smaller than the diameters of the leading file (b) A portion of the center line of the connecting portion (b-1, c-1) extending from the center line of the preceding file (b) and the trailing file (c) is opened at a certain oblique angle.

The ground wall file step S40 is a step in which the extension bit of the excavation rod 115 is punched through the trailing excavation hole e at a position adjacent to the preceding file b to form the left vibrating unit 20 and the right vibrating unit 20, And the trailing file c is introduced into the trailing excavation hole e at the same time so that the trailing pile of the trailing excavating hole e and the trailing file c are intruded at the same time, 1) is inserted into the connection part (b-1) of the preceding file (b), the extension bit is extracted to the outside of the following file (c) And an excavating rod withdrawing step (S30) in which the excavator is in a state of being intruded into the excavation hole (e).

When the groundworm file step S40 is performed, the linking portion b-1 of the preceding file b, the trailing file c, the preceding file b, (S50) in which the concrete is laid on the ground wall to form an underground wall.

The graining step S50 is a step of performing a grazing step S50 in which a plurality of files, that is, a leading file b, a trailing file c, The concrete is poured into the connecting portion (b-1) of the preceding file (b) and the connecting portion (c-1) of the trailing file (c) The structural stability can be secured.
