Method for dismantling overwater concrete bridge
The invention discloses a method for dismantling an overwater concrete bridge. A floating crane is adopted, the floating crane comprises a floating carrier and a hoisting device, the hoisting device is arranged on the floating carrier, anchor rope winding and unwinding devices are arranged at the four corners of the floating carrier correspondingly, and each anchor rope winding and unwinding device is provided with an anchor rope. The method for dismantling the overwater concrete bridge comprises the following steps: S1, anchoring and positioning the floating carrier: enabling the floating carrier to stop in the side direction of a concrete section to be dismantled, and anchoring each anchor rope to complete positioning of the floating carrier; S2, dismantling the concrete section to be dismantled; sS3, retreating the floating carrier: loosening the anchor rope in front of the floating carrier, and synchronously tightening the anchor rope behind the floating carrier to make the floating carrier retreat to a preset position relative to the bridge; S5, transporting the floating carrier to the shore; S6, returning the floating carrier; and S7, cycling step S1 to step S6 until the bridge is dismantled. The method for dismantling the overwater concrete bridge has the following advantages: the operation efficiency and the operation safety can be improved, and the operation cost can be reduced.
本发明公开了一种水上混凝土桥梁的拆除方法，采用浮吊进行，浮吊包括漂浮载体和起吊装置，起吊装置设于漂浮载体上，漂浮载体的四角处分别设有锚绳收放装置，各锚绳收放装置上均设有锚绳，水上混凝土桥梁的拆除方法包括如下步骤：S1：漂浮载体抛锚定位：将漂浮载体停靠于待拆混凝土段的侧方位，各锚绳抛锚，完成漂浮载体定位；S2：待拆混凝土段的拆除；S3：漂浮载体退移：松放漂浮载体前方的锚绳，同步收紧漂浮载体后方的锚绳，使漂浮载体相对桥梁退移至预定位置；S5：漂浮载体运输靠岸；S6：漂浮载体返程；S7：循环S1至S6步骤，直到桥梁拆除完成。该水上混凝土桥梁的拆除方法具有能够提高作业效率、作业安全性和减少作业成本等优点。
