预应力混凝土连续箱梁具有行车平顺、整体性好、外形美观的优点,自从近代出现以来,在桥梁工程特别是大型桥梁和市政工程领域得到了广泛的应用。随着连续梁的总体长度的增长,连续梁的施工将面临着诸多的问题。以颍河特大桥引桥U6联为超长预应力连续箱梁采用膺架现浇法施工为例,深入剖析施工工艺,对其各工序施工工艺进行技术总结。 Prestressed concrete continuous box girder with smooth driving, good overall, beautiful appearance advantages, since the modern appearance, in the bridge engineering especially large bridges and municipal engineering has been widely used. With the continuous growth of the overall length of the beam, continuous beam construction will face many problems. Take the Ying River Bridge Bridge U6 as the ultra-long prestressed continuous box girder using the cast-in-place construction as an example, in-depth analysis of construction technology, technical summary of its construction process.
