软弱基础钢管贝雷支架施工技术

Construction Technology for Steel Pipe Berea Support on Soft Subsoil Foundation

通过某高速铁路黄河南引特大桥支架施工,介绍了软弱地基条件下采用预应力管桩进行地基处理,钢管立柱贝雷梁支架搭设及预拱度设置等施工工艺,使安全、质量、进度都得到了充分的保证,证明了此方案的可行性。

Based on the support construction of Yellow River Nanyin super major bridge on a high-speed railway, this paper describes the construction technologies such as foundation treatment with prestress tube pile for soft subsoil foundation, setting up support with steel pipe Berea beam, camber setting etc. which ensures the project of its safety, quality and rate of progress and the scheme is proved feasible.
