The cylindrical pile wall can form tight waterproof layer together with the soil of pile core and will not form interface gap during deposition. The waterproof layer can prevent t he underground water from seepng along the pile wall surface to lower the bearing capacity of the pile. In addition, the other measures,including waterproof line, toothed mouthof pile tip and pre-pressed stress, can further raise the anti-seeping property of the waterproof layer and maintain the bearing capacity of the pile.
