UNDERGROUND COLUMN WALL CONSTRUCTION METHOD USING WATERSTOP RUBBER AND GEO-TUBE AND UNDERGROUND COLUMN WALL THEREWITH
The present invention relates to an underground column wall construction method using water stop rubber and geo-tube and an underground column wall built by using the same. With the present invention, the geo-tube provided with the water stop rubber can be positioned at the boundary between an established pole and a spot placing concrete column, and thus water stop performance can be maximized. The underground column wall construction method includes (a) constructing the established poles apart from each other; (b) forming a perforation hole (B) for the spot placing concrete column between the established poles and bringing the outer peripheral surface of the perforation hole into contact with the established pole boundary to prevent an overlapping portion (A) from being formed; (c) inserting the geo-tube having water stop rubber fixed on both sides thereof into the perforation hole (B) so that the water stop rubber is positioned at the boundary (A) between the established pole and the spot placing concrete column; and (d) placing and curing the on-site concrete (C) in the geo-tube so that the water stop rubber expands at the boundary and water stop performance is ensured at the boundary.
기성말뚝과 현장타설 콘크리트 말뚝의 경계부에 수팽창지수재가 구비된 지중튜브가 위치할 수 있도록 하여 차수성능을 최대한으로 확보할 수 있는 수팽창지수재와 지중튜브를 이용한 주열식 지중벽체 시공방법 및 이를 이용하여 시공된 주열식 지중벽체에 관한 것으로서, 상기 주열식 지중벽체 시공방법은 (a) 기성말뚝을 서로 이격시켜 시공하는 단계; (b) 상기 기성말뚝 사이사이에 현장타설 콘크리트말뚝용 천공홀(B)을 형성시키되 상기 천공홀의 외주면이 기성말뚝 경계부에 접하도록 하여 중첩부(A)가 형성되지 않도록 하는 단계; (c) 양 측면에 수팽창지수재가 고정 설치된 지중튜브를 상기 천공홀(B)에 삽입시켜 기성말뚝과 현장타설 콘크리트말뚝의 상기 경계부(A)에 수팽창지수재가 위치하도록 하는 단계; 및 (d) 상기 지중튜브 내부에 현장타설 콘크리트(C)를 타설 및 양생시켜 수팽창지수재가 경계부에서 수팽창 하면서 경계부에서 차수성능이 확보되도록 하는 단계;를 포함한다.
