Bridge construction method of first casting in place, then rotating and then pushing
The invention discloses a bridge construction method with cast-in-place, rotation and pushing in sequence, and relates to the technical field of bridge construction. Comprising the following steps: S1, surveying and setting out; s2, existing line protection; s3, constructing a pile foundation and a bearing platform; s4, pier column and swivel structure construction; s5, the No.0 block is constructed; s6, construction of a suspended pouring section; s7, adjusting hanging basket equipment; s8, steel-concrete combined section construction; s9, bridge rotation; s10, pushing preparation is carried out; and S11, the steel box girder is installed through an incremental launching method. According to the invention, the two main spans which are far away from each other can be closed after the bridge is rotated, a pier does not need to be built between the two main spans, and the influence on the existing line during construction is reduced.
本发明公开了一种先现浇、后转体、再顶推的桥梁施工方法，涉及桥梁建设技术领域。包括以下步骤：S1、测量放线；S2、既有线防护；S3、桩基及承台施工；S4、墩柱及转体结构施工；S5、0号块施工；S6、悬浇段施工；S7、调整挂篮设备；S8、钢混结合段施工；S9、桥梁转体；S10、顶推准备；S11、顶推法安装钢箱梁。本发明可以在桥梁转体后使两个相距较远的主跨合龙，无需在两主跨之间修建桥墩，降低了施工时对既有线的影响。
