简要介绍了混凝土箱梁现浇施工的三种方法,并比较了三种方法的优缺点。针对广深沿江高速公路深圳段第三合同段海上30m跨现浇箱梁部分的不同类型的箱梁结构,采用了不同的箱梁现浇施工法,即传统移动模架法、钢管支架现浇法、新型移动模架法;并进行了多项技术创新及运用,解决了浅海规模化箱梁现浇施工难题,创造了明显的综合效益。
Three methods for cast-in-place concrete box girder construction are briefly introduced, and the advantages and disadvantages of the three methods are compared. According to the different types of box girder structures of the 30m-span on-site box girder at the third contract section of Shenzhen section of Guangzhou-Shenzhen-Yanjiang Expressway, different cast-in-place construction methods of box girder are adopted, that is, France, the new method of mobile formwork; and carried out a number of technological innovation and application of shallow shallow sea to solve the problem of cast-in-place box girder construction, and create significant overall benefits.
