Detail
        
        The invention provides a technology that provides an efficient method for facilitating the compaction of the ground using a casing pipe in ground improvement work.
To this end, a ball-type casing is used to maintain the air pressure inside the casing pipe constant, and a ball is used at the bottom of the casing pipe to discharge gravel, thereby forming a uniform and continuous underground structure.
Through this, work efficiency such as increased construction quality and shortened construction period can be improved.
