摘要

The present invention relates to a casing assembly comprising: a circular casing body inserted into the ground-to-be-worked to form a perforation hole, and having an opening formed in a circumferential area at one side thereof; a pair of flanges coupled to each other at both sides of the opening while being spaced apart from each other by a predetermined distance in the circumferential direction of the casing body; and a support inserted between the flange and the casing body to support the flange, wherein the casing body is inserted into the ground-to-be-worked such that a first engaging hook of a pre-installed first sheet pile is disposed in an engaging space formed between the opening and the flange, and a second sheet pile is inserted into the ground-to-be-worked in a state where a second engaging hook of a second sheet pile coupled to the first sheet pile and the first engaging hook are hooked with each other in the engaging space.
