Horizontal thrust overpass bridge dismantling method
The invention discloses a horizontal thrust overpass bridge dismantling method. The dismantling method comprises the following steps that S1, a bridge floor is pre-cut; a bridge floor structure behind a main arch ring is cut and dismantled, so that only arch legs connected with a ground structure object are reserved on the overpass bridge; S2, the bridge body is pre-jacked; a preset vehicle-mounted device is used for driving to the bridge bottom of the bridge floor structure in the step S1 for positioning, and then the bottom of the bridge floor structure is pre-jacked according to the self-weight load of a moved bridge body; s3, arch legs are cut off; the arch legs connected with the ground structure are cut and dismantled, and the dismantled bridge deck structure falls onto the vehicle-mounted equipment; step S4, the bridge body is removed; and after the bridge body structure is integrally jacked by a certain height through the vehicle-mounted equipment, the bridge body structure is moved to a temporary site on the outer side of a road. The method has the technical effect of quickly dismantling the overpass bridge and can be widely applied to the technical field of bridge dismantling.
本发明公开了一种水平推力的跨线桥的拆除方法，包括以下步骤：步骤S1，桥面预切；将主拱圈后方的桥面结构切割拆除，使跨线桥只预留与地面结构物连接的拱腿；步骤S2，桥体预顶；利用预设的车载装备行驶至步骤S1中所述桥面结构的桥底进行定位，然后按移运桥体自重荷载对所述桥面结构的底部进行预顶；步骤S3，切除拱腿；将所述与地面结构物连接的拱腿进行切割拆除，使所述被拆除后的桥面结构落入所述车载装备上；步骤S4，桥体移除；利用所述车载装备整体顶升桥体结构一定高度后，移运桥体结构至道路外侧的临时场地。本发明具有快速拆除跨线桥的技术效果，可广泛应用于桥梁拆除技术领域。
