Abstract: The construction techniques of cast-in-situ concrete thin-wall pipe pile(referred to PCC pile) is introduced and tested based on the application of PCC pile in the soil improvement of Yan-Tong expressway, Jiangsu Province. The collapse degree of concrete, velocity of pile extraction, sequence of pile installation and fullness coefficient of concrete of PCC pile during construction are studied in detail. On the other hand, the methods of PCC pile quality detection are discussed; and the possible problems during construction and countermeasures are discussed too.

Key words: PCC pile, construction technique, quality detection
