Dismantling method of expressway overline farming bridge
The invention discloses a demolition method of an expressway overline farming bridge, belongs to the field of bridge demolition, and solves the problems that the existing overline farming bridge demolition needs to close traffic for a long time, the demolition period is long and the cost is high. Comprising the steps that a bailey beam support system is arranged beside each pier column of the overline farming bridge to be dismantled, and the two ends of each bailey beam support system are connected with a foundation and the bottom of a beam body respectively. And a bridge erecting machine is arranged above the overline farming bridge. The connection position of each bailey beam support system and the beam body serves as a boundary, and the beam body is divided into a plurality of block sections. And carrying out single-width temporary traffic control on the expressway below the block section before the block section is lifted. And each block section is cut, lifted, disassembled, cut, crushed, cleared and transported along the boundary line, then the pier column below the block section is cut and crushed, and the bailey beam support system which is not stressed any more is dismantled. Normal passage of the expressway in the construction period can be guaranteed. Meanwhile, the dismantling construction period is short, and the dismantling cost is low.
本申请公开了一种高速公路跨线农耕桥的拆除方法，属于桥梁拆除领域，解决了目前跨线农耕桥拆除需长时间封闭交通、拆除工期长以及成本高的问题。包括：在待拆除跨线农耕桥的每个墩柱旁分别设置贝雷梁支架体系，且每个贝雷梁支架体系的两端分别与基础和梁体的底部连接。在跨线农耕桥的上方安装架桥机。以每个贝雷梁支架体系与梁体的连接位置作为分界线，将梁体分为多个块段。在提吊块段前对块段下方的高速公路进行单幅临时交通管制。沿分界线对每个块段进行切割、提吊、解体切割以及破碎清运，之后将块段下方的墩柱切割破碎，并拆除不再受力的贝雷梁支架体系。本申请能够保证施工期间高速公路的正常通行。同时，拆除工期短、拆除成本低。
