CASING ASSEMBLY CINBINED FLANGE AND SHEET PILE BUILDING METHOD USING THEREOF

摘要

The present invention relates to a casing assembly, comprising a circular casing main body which is inserted into the ground to be constructed to form a perforated hole and has an opening on a region in the circumferential direction; a pair of flanges which is arranged on both sides based on the opening and is combined to be spaced a predetermined distance apart in the circumferential direction of the casing main body; and a support which is inserted between the flanges and the casing main body, wherein a first combining ring of a pre-constructed first sheet pile is inserted into the ground to be constructed to be arranged in a combining space spaced between the opening and the flanges. While a second combining ring of a second sheet pile adjacently combined with the first sheet pile is combined with the first combining ring in the combining space, the second sheet pile is inserted into the ground to be constructed.
