Combined type front fulcrum hanging basket dismantling method
The invention relates to a combined type front fulcrum hanging basket dismantling method which comprises the following steps: after the last section of main beam is dismantled, installing a hanging basket integral lowering sling on a bridge floor, dismantling an original anchoring system of the hanging basket, and converting a bearing platform stress system into a lowering sling system; then the floating box is pulled to the position below the hanging basket under the bridge, the hanging basket bearing platform is overall lowered to the floating box through a bridge floor lowering lifting appliance, the bearing platform is transported to the position beside a main pier platform in a floating mode through the floating box, and block-by-block dismantling is conducted through a crane; and dismantling the bridge floor, lowering the hanger, dismantling the hanging basket triangular truss on the bridge floor, and completing hanging basket dismantling construction. The hanging basket dismounting method is suitable for dismounting the hanging basket in the shallow water area under the bridge, the combined hanging basket dismounting scheme of overall hanging basket lowering and buoyancy tank transferring is adopted, cost is low, and safety is high.
本发明涉及一种组合式前支点挂篮拆除方法，最后一段主梁拆模后，在桥面安装挂篮整体下放吊具，拆除挂篮原锚固系统，将承载平台受力体系转换至下放吊具系统；然后将浮箱牵引至桥下挂篮下方，利用桥面下放吊具将挂篮承载平台整体下放到浮箱上，利用浮箱将承载平台浮运至主墩平台旁，利用吊车分块拆除；组后拆除桥面下放吊具，在桥面拆除挂篮三角桁架，完成挂篮拆除施工。本发明适用于桥下为浅水区时挂篮拆除，采用挂篮整体下放+浮箱转运的组合式挂篮拆卸方案，成本低，安全性高。
