随着我国高速公路建设速度的加快和规模的不断加大,预应力箱梁的预制施工在越来越多的工程中得到应用。文章通过对预应力箱梁施工工艺、施工的重点难点的研究,对预应力箱梁的模板制作、钢筋的加工等等细节方面进行了深入的探讨。旨在为预应力箱梁预制效果的提高提供实践经验的参考。 With the speeding up of construction of expressway in our country and increasing of scale, prefabricated construction of prestressed box girder has been applied in more and more projects. In this paper, the construction process of prestressed box girder, the construction of the key and difficult research, the prestressed box girder stencil making, steel processing and so on in detail were discussed in depth. The purpose of this paper is to provide practical experience for improving the prefabricated precast box girder effect.
