Ultrahigh tower area beam section installation method under hoisting limited condition
The invention relates to the technical field of bridge construction, in particular to an ultrahigh tower area beam section installation method under the condition of hoisting limitation. The method comprises the following steps that S1, a main beam assembling support is installed on a lower tower column; s2, the support is hoisted to the middle tower column; s3, splicing of the 0 # block main beam is completed on the main beam splicing support, the 0 # block main beam is dragged to the designed installation position, the support is dragged to the support installation position, and the support and the 0 # block main beam are fixedly connected; s4, the 0 # block main beam is temporarily limited and fixed; s5, the 1 # main beam and the 0 # main beam are connected; and S6, the second main beam is spliced in a suspended mode, the first stay cable corresponding to the second main beam is installed and tensioned, and installation of the tower area beam section is completed. According to the method, the main beam assembling support is constructed on the lower tower column, the tower area 0 # block main beam is installed in the mode that assembling is conducted firstly and then moving is conducted, the support is installed in the mode that hoisting is conducted firstly and then deflection moving is conducted, the problem that hoisting of the ultrahigh cable-stayed bridge tower area is limited is solved, and the difficulty of installation of the tower area main beam is reduced.
本发明涉及桥梁建设技术领域，具体地指一种起重受限条件下超高塔区梁段安装方法。按照以下步骤进行：S1、在下塔柱上安装主梁拼装支架；S2、将支座吊装至中塔柱上；S3、在主梁拼装支架上完成0#块主梁的拼装，牵引至设计安装位置，牵引支座至支座安装位，完成支座与0#块主梁固结；S4、对0#块主梁进行临时限位固定；S5、对1#块主梁与0#块主梁进行连接；S6、悬拼2#块主梁，对2#块主梁对应的1#斜拉索进行安装和张拉，完成塔区梁段的安装。本申请通过在下塔柱构建主梁拼装支架，采用先拼装后移动的方式安装塔区0#块主梁，采用先吊装后偏转移动的方式安装支座，解决了超高斜拉桥塔区吊装受限的难题，降低了塔区主梁安装的难度。
