Construction method of deep soft foundation box girder composite support
The invention belongs to the technical field of box girder composite support construction, and particularly relates to a deep soft foundation box girder composite support construction method which comprises the following steps: step 1, construction preparation and surveying and setting out; a prestressed pipe pile point position is released according to the pile position design drawing, lime is scattered for pile position marking, and measured data are checked; secondly, a prestressed pipe pile is driven, and a strip-shaped foundation is constructed; the single row of pipe piles are driven symmetrically from the middle to the two sides according to a pipe pile design drawing. According to the construction method of the deep soft foundation box girder composite support, through operation of the prestressed pipe pile and the strip-shaped foundation, compared with a conventional steel pipe pile, the foundation treatment mode is high in driving speed, convenient to construct and high in foundation bearing capacity, in the box girder cast-in-place construction process, the overall settlement amount of the support is small, deformation is small, stability is high, uneven settlement does not occur, and the construction quality of the box girder is ensured.
本发明属于箱梁复合支架施工技术领域，尤其是一种深厚软基箱梁复合支架施工方法，包括以下步骤，步骤一、施工准备及测量放线；根据桩位设计图放出预应力管桩点位，撒石灰进行桩位标记，并对测量数据进行校核；步骤二、预应力管桩打设及条形基础施工；单排管桩打设按管桩设计图由中间向两边对称施打。该深厚软基箱梁复合支架施工方法，通过预应力管桩+条形基础操作，地基处理方式相比常规钢管桩，打设速度快，施工便捷，基础承载力高，箱梁现浇施工过程中支架整体沉降量小，变形小，稳定性高，未发生不均匀沉降，确保了箱梁施工质量。
