预应力混凝土道岔连续箱梁施工技术探讨

Explore the concrete continuous box girder construction technology

文章结合某预应力连续箱梁施工实例,针对该工程中梁箱与腹板钢筋密集,而且同时存有波纹管,箱梁内部空隙较小,对混凝土施工提出更高要求,总结出本工程混凝土施工的各个环节,提出混凝土裂缝预防控制措施,为同类工程提供参考实例。

This paper combining the construction of a prestressed concrete continuous box girder, a centre sill box for this project with web reinforcement with dense, and at the same time being corrugated pipe, small box girder internal gap, puts forward higher requirements to concrete construction, sums up the engineering concrete construction of each link, the concrete crack prevention and control measures are put forward, provide reference for the similar engineering instance.
