在滨海多雨软弱地基区域现浇箱梁施工中,采用钢管柱和贝雷片作为支架,与满堂支架式工法相比,可避免大面积地基处理,且不用考虑基础受雨水浸泡变软弱等因素影响,安全质量可靠性高,特别是大批量使用时经济效益、进度效益明显。以沈海复线宁德漳湾至连江浦口高速公路宁德段飞鸾互通立交五十余跨现浇梁施工为例,文章主要介绍贝雷梁柱式支架的基本构造以及在互通立交施工中的实际应用经验。
In the construction of cast-in-place box girder in the coastal rainy and weak foundation area, the steel pipe column and the Berets are used as the brackets. Compared with the full-scale scaffolding method, the foundation treatment can be avoided without considering the weakening of the foundation due to the rain soaking , Safety and reliability of high quality, especially when using large quantities of economic benefits, the progress of the obvious benefits. Taking the construction of more than 50 cast-in-place beams at the Ningde section of Ningde Zhangwan-Linjiang-Pukou Expressway of Shenhai-Fuxing-Ningxia Expressway as an example, the article mainly introduces the basic structure of Berea beam-column brackets and the actual construction Application experience.
