STBC - SRII pile (Steel pipe reinforced Taishin bashouchi Concrete Super Rib II pile) is a composite placement pile developed for improving earthquake resistance. Parts where large bending moment and shear force are applied, such as convenient cast concrete pile heads were strengthen together with steel pipe which have inner surface protusion by welding.
Construction method
In the construction method of the STBC pile, the structure of the steel pipe concrete part is carried out by-
(1) Simultaneous steel pipe construction method.
Drilling of steel pipe concrete and shaft part, construction of reinforcing bar, cocnrete placing etc, are carried out by all casing method, earth drill construction method, reverse circulation drill construction method.
In addition, construction of the bottomed pile is carried out by the Japanese Construction Center evaluation method, the HND construction method and the SY construction method.
