Application of large box steel structure components in protection program for Boxi pipelines project

Because the large box steel structure is suitable for soft soil foudation,it is successfully applied to the protection program of Boxi pipelines project.The technical problem caused by crisscross of Boxi pipelines and engineering construction in the No.11 section of the first-stage project of mudflat development has been solved successfully.And it also creates precondition for the closure of breakwater.The large box steel structure project is the pioneering project in the marine works construction.This paper presents a description of the method and technology of the large box steel structure components utilized in protection works for Boxi pipelines project.
