Swivel construction method of continuous beam bridge
The invention discloses a swivel construction method of a continuous beam bridge, which relates to the technical field of bridge swivel construction, and comprises the following steps: constructing a middle pier, and constructing a side pier on each of the two sides of the middle pier; a counter-force supporting assembly is erected between each side pier and the middle pier, and the counter-force supporting assemblies are fixedly connected with the side piers; the rotating steel beam is placed on the middle pier, and the rotating steel beam is rotated so that the two cantilever ends of the rotating steel beam can be placed on the counter-force supporting assemblies correspondingly; a butt joint boundary beam is installed on each side pier; the counter-force supporting assembly is used for jacking the rotating steel beam, and the rotating steel beam is adjusted to the preset closure position; and the cantilever end of the rotating steel beam is in closure butt joint with the butt joint edge beam. The counter-force supporting assemblies are arranged between the side piers and the middle piers, so that sinking of the cantilever end of the rotation beam can be resisted through counter-force supporting in bridge rotation construction, and a large amount of cost input is not needed to build a temporary tower.
本发明公开了一种连续梁桥的转体施工方法，涉及桥梁转体施工技术领域，其包括以下步骤：施工中墩，并在中墩的两侧各施工一个边墩；在每个边墩和中墩之间架设反力支撑组件，并将反力支撑组件与边墩固结；将转体钢梁落放于中墩上，并对转体钢梁进行转体以使转体钢梁的两个悬臂端分别落放于一个反力支撑组件上；在每个边墩上安装对接边梁；使用反力支撑组件起顶转体钢梁，并将转体钢梁调整至预设合龙位置；将转体钢梁的悬臂端与对接边梁合龙对接。本申请中通过在边墩和中墩间设置反力支撑组件，使得桥梁转体施工既可以通过反力支撑对抗转体梁悬臂端的下沉，又不需要花费大量成本投入去建造临时塔。
