Abstract: Thin-wall pipe pile using cast-in-situ concrete(PCC) with vibrated and steel tube mould technology is a patent for ground improvement invented by the authors. This new style pile is suitable for wide application to soft soil areas which can increase ground bearing capacity and reduce the ground settlement remarkably. The technical principle, soil improvement mechanism, the construction equipment and technology, the design and detection method are introduced in detail. It is concluded that the new style pile overcomes the shortage of traditional one and has following advantages, high bearing capacity, reliable quality and low cost, it is expected to be great applying prospect in ground improvement.

Key words: cast-in-situ, thin-wall pipe pile, composite foundation, bearing capacity, deformation
