In response to the problem of insufficient length of the 0#block of the(32+48+32)m double track continuous beam of the Chaoling Dedicated Line crossing the Jinfu Expressway Extra Large Bridge,precise installation of hanging baskets and optimization of the BIM technology modeling construction plan were carried out.One side of the hanging basket was used to arrange the suspended pouring of 1#block in a staggered manner,avoiding the process of setting up and removing the 1#block bracket,as well as the use of special hanging baskets.This has reference significance for similar projects with limited site conditions and no conditions for setting up the 1#block bracket.
