Construction method of cross-sectional expansion type columnar barrier wall
The present invention discloses a method for constructing a cross-sectional expansion type columnar barrier wall. The present invention provides a method in which an overlap cylindrical tube is drawn out using a vibration device (vibrator) when repeatedly constructing the overlap cylindrical tube into which H-beams and reinforcing bars are selectively inserted using an outer cylindrical tube, pouring concrete inside the overlap cylindrical tube, and then drawing out the overlap cylindrical tube. The present invention provides a sheathing barrier wall that strengthens the compaction density of the poured concrete without installing a separate hose for filling a gap between concrete piles (pillars) with a filler, while expanding the cross-section of concrete piles (pillars) at the same time. The present invention repeatedly implements a first process, a second process, and a third process, wherein the first process is for drilling a circular hole and then digging out the soil in the hole, the second process is for inserting an overlap cylindrical tube, and the third process is for drawing out an outer cylindrical tube.
본 발명은 단면 확장형 주열식 차수벽 시공방법을 개시한다. 이러한 본 발명은 외측 원통관을 이용하여 H빔과 철근이 선택적으로 삽입되는 오버랩 원통관을 반복 시공하면서 오버랩 원통관 내부에 콘크리트를 타설한 후 오버랩 원통관을 인발시, 진동장치(바이브레이터)를 이용하여 오버랩 원통관 인발이 이루어지는 공법을 제공하면서, 콘크리트 말뚝(기둥) 사이로 충진재를 충진하기 위한 호스를 별도로 설치하지 않더라도 타설된 콘크리트의 다짐 밀도를 강화시키고, 동시에 콘크리트 말뚝(기둥)의 단면을 확장시키면서 연속적이고도 안정적인 차수 효과를 가진 흙막이 차수벽을 제공하는 것이다.
