Split-level asynchronous horizontal rotation construction method for overline double-beam bridge
The invention relates to a split-level asynchronous horizontal rotation construction method for an overline double-amplitude beam bridge, which comprises the following steps of: sequentially carrying out suspended pouring and rotation on two amplitude bridges at different heights, completing rotation construction on a left amplitude bridge according to a conventional method, arranging a heightened turntable bracket on the periphery of a main span pier body of a right amplitude bridge, and pouring and rotating the right amplitude bridge at a height higher than that of the left amplitude bridge, after the right width bridge rotates in place, a beam falling support is erected below the bridge, a jack is arranged on the beam falling support, the heights of the rotating disc support and the beam falling support are alternately reduced through jacking and contracting of the jack, and the right width bridge falls to the designed height. According to the cross-line double-width bridge swivel construction method, through staggered-layer asynchronous flat rotation of the two bridges, mutual influence during swivel of the two bridges is avoided, and swivel construction of the cross-line double-width bridge is smoothly achieved.
本发明涉及一种跨线双幅梁桥错层异步平转施工方法，将两幅桥分不同高度先后进行悬浇和转体，左幅桥先按常规方法完成转体施工，然后在右幅桥主跨墩身外围设置加高转盘支架，右幅桥以高于左幅桥的高度进行浇筑和转体，右幅桥转体到位后在桥下搭设落梁支架，落梁支架上设置千斤顶，通过千斤顶顶升和收缩，交替降低转盘支架和落梁支架的高度，将右幅桥落梁到设计高度。本发明通过两幅桥错层异步平转，避免两幅桥转体时相互影响，顺利实现了跨线双幅桥的转体施工。
