Construction method for heightening single-span hollow bridge
The invention discloses a construction method for heightening a single-span hollow bridge, which belongs to the field of bridge engineering and comprises the steps of removing bridge deck pavement, relieving beam end constraint, arranging a construction bracket and lifting equipment, designing, manufacturing and installing lever equipment, installing a jack and arranging monitoring equipment. The whole lifting process is subjected to whole-process monitoring, whole synchronous jacking test, lifting construction, support cushion stone pouring, manufacturing and mounting, bridge center retesting and beam plate returning; according to the invention, no damage is caused to the bridge, the overall structure of the beam slab is safe, the hinge joint is not damaged, the problem of asynchronous jacking caused by backward construction operation or equipment in the jacking construction process under the bridge is solved, and the construction is safe and economical.
本发明公开了一种独跨空心桥加高的施工方法，属于桥梁工程领域，该施工方法包括去除桥面铺装、解除梁端约束、施工支架及提升设备安置，杠杆设备的设计及制安、千斤顶安设及监控设备的安置，对整体提升过程进行全程监控、整体同步试顶升、提升抬高施工、浇筑支座垫石及制作安装以及桥梁中心复测及梁板回位；本发明不会对桥梁造成任何破坏，梁板整体结构安全，不损坏铰缝，解决了在桥下进行顶升施工过程中由于施工操作或者设备的落后造成的顶升不同步的问题，施工安全、经济。
