| Abstract: | Most of the foundations of the offshore approach spans of Hangzhou Bay Sea-Crossing Bridge are designed to use the large diameter and very long steel pipe piles.In the massive fabrication of the steel pipe piles,a serious of technical problems involved in the fabrication is satisfactorily resolved and a set of fairly perfect workmanship for the fabrication is formed.The fabrication of the steel pipe piles of the Bridge features small land occupancy area,high automization degree,high fabrication efficiency and stable fabrication quality.This paper describes the fabrication arrangement in workshop,work flow design,principles of fabrication of the piles with spiral method and welding procedures for the piles with variable wall thickness. |
