DEVELOPMENT AND APPLICATION OF THE LARGE-DIAMENTER

DRIVEN CAST-IN-PLACE CONCRETE THIN-WALL PIPE PILE

1: 1: ABSTRACT

A new form of driven Cast-in-place Concrete thin-wall Pipe pile (referred as PCC pile) developed independently by GeoHohai recently has been patented in China. PCC piles are rapidly increasing in popularity as one of the most cost-effective soft ground improvement techniques in China since its first application.

The field study has demonstrated that PCC pile composite foundation is a cost-effective way to enhance ground bearing capacity and reduce settlement. Compared with traditional piling practice, the paper concludes with the statement on the potential application value of PCC pile with regard to other traditional piling techniques as being high bearing capacity, easily controlled and reliable quality and low construction cost.
