Dismantling method of bridge underwater structure
The invention discloses a method for dismantling an underwater structure of a bridge, which comprises the following steps: step 1, after an overwater structure of the bridge is dismantled, driving a steel structure cofferdam around the underwater structure of the bridge; secondly, four-corner inclined struts are installed, and cross braces are symmetrically installed between the bridge underwater structure and the steel structure cofferdam; thirdly, water is pumped through water stopping measures, and the water stopping effect is checked to be qualified; and fourthly, the bridge underwater structure is dismantled section by section, the cross brace between the dismantled section and the steel structure cofferdam is removed, meanwhile, the cross brace is installed between the steel structure cofferdam on the opposite side of the dismantled section, and bottom cleaning is conducted. A waterproof environment can be defined and is not influenced by a water body environment, an underwater structure can be quickly dismantled conveniently, and the construction efficiency and the construction safety are improved.
本发明公开了一种桥梁水下结构的拆除方法，包括以下步骤：步骤一，待桥梁水上结构拆除后，在桥梁水下结构周围打入钢结构围堰；步骤二，安装四角斜撑，桥梁水下结构与钢结构围堰之间对称安装横撑；步骤三，采用止水措施抽水，检查止水效果至合格；步骤四，分节段拆除桥梁水下结构，移除正在拆除的节段与钢结构围堰之间的横撑，同时在已拆除的节段的对侧钢结构围堰之间安装横撑，清底。本发明能够围合形成隔水环境，不受水体环境影响，便于水下结构的快速拆除，提高了施工效率和施工安全。
