Pier dismantling construction method of existing bridge
The invention belongs to the technical field of pier dismantling construction, and particularly relates to a pier dismantling construction method of an existing bridge. The method comprises the steps that a temporary supporting system is arranged near a to-be-dismantled bridge pier to jack a bridge span; a cutting sequence and cutting blocks are designed, and all cutting lines are drawn on the pier to be dismantled; arranging a rope cutting construction platform for placing diamond rope saw cutting equipment, and arranging hoisting equipment on the bridge span; a plurality of lifting holes corresponding to the cutting blocks are formed in the bridge span, the lifting end of the lifting device penetrates through the lifting holes to be connected to one cutting block, the diamond wire saw cutting device is used for cutting the cutting block, and after cutting is completed, the lifting device is used for lowering the cutting block and transporting the cutting block outwards. And block cutting, lowering and transferring of a tie beam, a cover beam and two pier columns of the to-be-dismantled pier are sequentially completed according to the cutting sequence. Damage and influence on the existing bridge and the surrounding environment during bridge pier dismantling construction can be reduced, and the safety of bridge pier dismantling construction of the existing bridge is improved.
本发明属于桥墩拆除施工技术领域，具体涉及一种既有桥梁的桥墩拆除施工方法。该方法包括，在待拆除桥墩附近设立临时支撑体系以对桥跨进行顶升；设计切割顺序及切割块，并在待拆除桥墩上画出所有切割线；设置绳切施工平台以放置金刚石绳锯切割设备，在桥跨上设置吊放设备；桥跨上开设有与多个切割块相对应的多个吊放孔，吊放设备的吊放端穿过吊放孔连接于一切割块上，利用金刚石绳锯切割设备对该切割块进行切割，切割完成后利用吊放设备下放该切割块并外运，按照切割顺序依次完成待拆除桥墩的系梁、盖梁及两个墩柱的分块切割、下放及转运。本发明能够降低桥墩拆除施工时对既有桥梁及周边环境的破坏及影响，提高既有桥梁桥墩拆除施工的安全性。
