随着公路建设大规模展开,为适应各种不同环境下建设需要,在公路设计中对桥梁结构类型的选定要求将越来越高,大跨径、高应力的桥梁结构不断得到广泛应用,箱梁结构的应用更是层出不穷。于是,为确保箱梁施工质量,对箱梁施工技术的工艺控制就显得格外重要,如何使得浇筑出来的箱梁达到内实外美的效果,需要把握好箱梁施工过程中几大质量控制点的控制,因此,下面就让我们针对预应力现浇箱梁施工技术的相关要求进行探讨,以供同行参考借鉴。
With the large-scale development of highway construction, in order to meet the needs of construction in various environments, the type selection of bridge structure in the highway design will be more and more demanding. The bridge structure with large span and high stress is continuously applied. The application of box girder structure is more and more emergent. Therefore, in order to ensure the construction quality of the box girder, the process control of the box girder construction technology is of particular importance. How to make the box girder that is cast out to achieve the goal of being both inside and outside the United States requires a good grasp of several major quality control points during the construction of the box girder Therefore, let us discuss the relevant requirements of prestressed cast-in-place box girder construction technology for reference of peers.
