Summary:The present invention relates to a construction method of a pier caisson well foundation using a PCC structure, which horizontally and vertically connecting PC blocks with each other to form the shape of a caisson well to sink to a floor foundation. Moreover, earth and sand in the caisson well is excavated for the PC blocks to be buried under the ground at a predetermined depth to insert a reinforcing bar into the inside of the caisson well and deposit and cure concrete mortar. Therefore, a small-scale and lower pier is more easily constructed to reduce manpower and further, significantly reduce a construction period for construction costs to be reduced. 본 발명은 PCC 구조를 이용한 교각 우물통기초 시공방법에 관한 것으로, 수평과 수직으로 PC블록을 상호 연결하여 우물통 형태로 형성하여 바닥기초에 침강시키되 우물통 내부의 토사를 파내어 지면에 일정 깊이로 묻히도록 한 상태에서 우물통의 내부에 철근을 배설하여 콘크리트 모르타르를 타설 양생함으로써 소규모의 하부 교각을 보다 용이하게 시공할 수 있도록 하여 작업 공수를 줄일 수 있도록 함은 물론, 작업 공기를 획기적으로 줄여 시공비를 줄일 수 있도록 한 기술에 관한 것이다.
