Temporary consolidation system and construction method for box girder of overpass unpass-keeping existing line
The invention relates to a temporary consolidation system and construction method for an over-span pass-keeping existing line box girder. The temporary consolidation system comprises a main pier structure, an auxiliary pier structure, a foundation structure, a temporary consolidation structure and an upper structure. The temporary consolidation structure is supported on the main pier structure, the auxiliary pier structure and the foundation structure through the floor steel pipe stand column group. Longitudinal beams and transverse beams are laid on the top of the floor steel pipe stand column group. And the box girder 0 # block is poured on the cross beam. The construction method has the beneficial effects that a temporary consolidation system with good overall stability is formed by adopting the floor steel pipe stand column group, additionally arranging a small bearing platform and an auxiliary pier bearing platform, additionally arranging a truss and a main bearing beam for penetrating connection, additionally arranging a small-diameter steel pipe for supporting and penetrating through the main bearing beam and the like, and a safe and stable operation platform is provided for the cast-in-place box girder; and the construction requirements of the continuous box girder 0 # block with large span, wide section, large volume and heavy dead weight can be met.
本发明涉及一种上跨保通既有线箱梁临时固结体系及施工方法，包括主墩结构、辅助墩结构、基础结构、临时固结结构和上部结构；所述临时固结结构通过落地钢管立柱群支撑在主墩结构、辅助墩结构和基础结构上，落地钢管立柱群顶部铺设有纵梁和横梁；箱梁0#块浇筑在横梁上。本发明的有益效果是：通过采用落地钢管立柱群、增设小承台+辅助墩承台、桁架+主承梁贯穿连接、增设小直径钢管支撑贯穿主承梁等方法，形成了具体整体稳定性良好的临时固结体系，为现浇箱梁提供了安全稳定的作业平台，能够满足跨度大、截面宽、方量大、自重重的连续箱梁0#块施工要求。
