后张法预应力小箱梁预制施工技术

On post-tensioned prestressed small box-girder precast construction technique

结合实际施工中小箱梁预制施工难的特点,从模板工程、混凝土工程、预应力筋施工等方面着重阐述了此类小箱梁预制施工工艺,解决了工程中常遇到的施工缝明显等问题,以期指导同类工程更好的施工。

Combining with the fact of the hard construction of the small box-girder precast construction, the paper illustrates the small box-girder precast construction craft from the mold plate projects, the concrete project, and the prestressed reinforcement construction and so on, and solves problems for example the obvious cracks in the projects, so as to direct the construction of similar projects.
