文章介绍了阻止箱梁内膜上浮的施工技术,即针对目前桥梁箱梁现浇施工中的不足,通过对箱梁模板加设横梁扁担、控制混凝土的塌落度、掌握振捣时间等因素,来阻止箱梁内模的上浮,从而保证箱梁模具的稳定性。因此,探讨和推进这种技术的改进和优化,对于保证施工质量是十分重要的。
In this paper, the construction techniques to prevent the inner membrane of the box girder from floating are introduced. In view of the shortcomings of the current cast-in-place construction of the box girder of the box girder, the flat pole of the beam is added to the box girder template to control the slump of the concrete, To prevent the box girder inner mold floating, so as to ensure the stability of box girder mold. Therefore, to explore and promote the improvement and optimization of this technology is very important to ensure the quality of construction.
