Hoisting method for cable-stayed bridge steel box girder
The invention provides a hoisting method for a cable-stayed bridge steel box girder. The hoisting method comprises the following steps that S001, a pair of lower guide rails is laid on the lower surface of each box girder section; S002, the starting segments of the box girder sections are hoisted, and then are connected to a main tower to form the steel box girder, and a bridge deck crane is assembled on the steel box girder; a girder transporting crane is assembled on the lower guide rails; S003, temporary lower guide rails are connected to the steel box girder; S004, the box girder sectionsare hoisted and then are transported to the temporary lower guide rails by the girder transporting crane; S005, the bridge deck crane is connected with the box girder sections, and the connection between the girder transporting crane and the box girder sections is disconnected; S006, the girder transporting crane is removed from the temporary lower guide rails, and the temporary lower guide railsare disassembled; S007, the height of the box girder sections is adjusted by the bridge deck crane, so that the box girder sections are aligned with the connecting end of the steel box girder, and thebox girder sections are connected with the steel box girder together; S008, the connection between the bridge deck crane and the box girder sections is disconnected, and the bridge deck crane is moved to the box girder sections; and S009, the contents in the above steps are repeated until the hoisting construction is completed.
本发明提出一种斜拉桥钢箱梁吊装方法，包括：S001：在每段箱梁节的下表面铺设一对下导轨；S002：将起始段箱梁节吊起后连接在主塔上形成钢箱梁，在钢箱梁上组装桥面吊机；在下导轨上组装运梁吊机；S003：在钢箱梁上连接临时下导轨；S004：通过运梁吊机将箱梁节吊起后并运输至临时下导轨上；S005：通过桥面吊机连接箱梁节，并断开运梁吊机与箱梁节的连接；S006：将运梁吊机从临时下导轨上移开，并拆除临时下导轨；S007：通过桥面吊机调整箱梁节高度，使箱梁节与钢箱梁的连接端对齐，并将箱梁节和钢箱梁连接在一起；S008：断开桥面吊机与箱梁节的连接，将桥面吊机移动到该箱梁节上；S009：重复以上步骤中的内容，直至吊装施工完毕。
