预应力管桩结合贝雷支架在箱梁施工中的应用

The application of box beam construction on combining with prestressed pipe pile and bailey truss

结合工程实例,着重介绍了预应力管桩与钢管柱贝雷片组成的支架的构造和在施工中的运用,实践证明:在软土地基客运专线现浇箱梁施工过程中,采用预应力管桩与钢管柱贝雷片支架相结合,可避免大面积处理地基,能够减少人员投入。

Combining with the particular example,this paper indicate the prestressed pipe pile and the steel pipe piles of bailey support＇s structure and the application of construction.It confirmes that the soft soil foundation passenger dedicated line castts box beam at the construction process.Adoption of combining with prestressed pipe pile and steel pipe pile bailey truss,the treatment of foundation with large-area can be avoided and the involvement of staff can be reduced.
