Construction method for cable-beam-free section of superposed beam cable-stayed bridge tower area
The invention discloses a construction method for a cable-beam-free section in a tower area of a superposed beam cable-stayed bridge. The construction method comprises the following steps of: 1, mounting a temporary cantilever hanging bracket; 2, mounting a middle beam section; 3, mounting a side span first beam section; 4, temporarily fixing the side span first beam section; 5, mounting a first main span beam section; 6, temporarily fixing the main span first beam section; 7, dismantling the temporary cantilever hanger and the temporary cable. The mode that a temporary cantilever hanging bracket, a temporary cable and a tower crane on a tower body bearing platform are combined and matched is utilized, no cable beam section exists in the hoisting tower area, a floating crane is not used, and an assembling support is not arranged; therefore, the method does not occupy a main channel, reduces the construction cost, prolongs the construction period and is low in safety risk.
本发明公开了一种叠合梁斜拉桥塔区无索梁段施工方法，包括步骤：一、临时悬臂吊架的安装；二、中间梁段的安装；三、边跨一号梁段的安装；四、边跨一号梁段的临时固定；五、主跨一号梁段的安装；六、主跨一号梁段的临时固定；七、临时悬臂吊架和临时索的拆除。本发明利用临时悬臂吊架、临时索和塔体承台上的塔吊结合配合的方式吊装塔区无索梁段，不使用浮吊，不下设拼装支架，不占用主航道、减少施工成本、提高工期，安全风险低。
