预应力混凝土现浇连续梁合龙段施工工艺

Construction Technology of Cast-In-Place Continuous Beam Closure Segment of Prestressed Concrete

对于预应力混凝土连续梁桥来说,其合龙段的施工质量对整个工程的施工质量具有重要的影响。因此,必须采取相应的措施,对其合龙段的施工质量进行提升。本文结合某铁路特大桥预应力混凝土现浇连续梁合龙施工段,较详细地介绍在钢筋密集、钢绞线形式复杂、施工期短、施工质量有特殊要求的情况下的施工方法,收到了明显的经济效益与社会效益,可供施工技术人员参考。

For the prestressed concrete continuous beam bridge,the construction quality of the closure segment has an important influence on the construction quality of the entire project.Therefore,corresponding measures must be taken to improve the construction quality of the closure segment.In this article,combined with the construction section of cast-in-place concrete continuous beam of a railway bridge,it is introduced in detail in the case of dense steel bars,complicated steel windings,short construction period,and special requirements for construction quality.It can be used for reference by construction technicians,which has received obvious economic benefits and social benefits.
