Truss structure double-splicing type adjustable bridge anti-overturning construction method
The invention discloses an anti-overturning construction method for a double-spliced adjustable bridge of a truss structure. The anti-overturning construction method comprises the steps that S1, a lifting steel hoop is manufactured; s2, manufacturing an I-shaped steel truss; s3, manufacturing a main stress steel hoop; s4, assembling on the ground; s5, overall lifting; according to the method, the I-shaped steel trusses arranged on the two sides of the pier column generate upward force on the bridge, and the column hoop arranged on the outer side of the pier column interacts with the pier column to provide the anti-overturning moment of the bridge. According to the method, the anti-overturning system is lifted in place in one step through the lifting steel hoop arranged at the top of the pier column, a large amount of aloft work is reduced, and the construction efficiency is improved through overall lifting and descending.
本发明公开一种桁架结构双拼式可调节桥梁防倾覆施工方法，包括S1、提升钢箍制作；S2、工字钢桁架制作；S3、主受力钢箍制作；S4、地面拼装；S5、整体提升；S6、预加压力：S7、高强螺栓安装：S8、架体拆除，本发明实现途径为墩柱两侧设置的工字钢桁架对桥梁产生向上的力、墩柱外侧设置柱箍与墩柱之间相互作用来提供桥梁的防倾覆力矩。该方法通过墩柱顶部设置的提升钢箍，实现防倾覆体系一步提升到位，减少了大量的高空作业，整体提升下降增加了施工效率。
