Construction method for special-shaped arch rib of through type basket rigid tied arch bridge
The invention discloses a construction method for a special-shaped arch rib of a through type basket rigid tied-arch bridge. The technical problem that the closure precision of multi-face and multi-side different curves is not easy to control is solved. The method comprises the following steps that S1, a temporary support is erected; s2, arch rib segments are prefabricated; s3, arch ribs are hoisted; and S4, the temporary support is disassembled. The device is simple in structure, scientific and reasonable in design and convenient to use, in the whole hoisting process, the total station is used for monitoring data of all point positions, accumulated errors are reduced, and it is ensured that the overall structure is linear and consistent; the steel member expands with heat and contracts with cold due to high and low temperature, strict air temperature control needs to be performed in the closure process, and accurate closure is ensured through temperature step curve technology control; for the installation of the complex through type basket rigid tied arch bridge arch rib, especially the special-shaped arch rib with the complex structure, the construction thought of the method is adopted, and good applicability is achieved.
本发明公开了下承式提篮刚性系杆拱桥异形拱肋施工方法，解决多面多边异曲线合龙精度不易控制的技术问题。本发明包括以下步骤：步骤S1：搭设临时支架；步骤S2：预制拱肋分段；步骤S3：吊装拱肋；步骤S4：拆除临时支架，即可。本发明结构简单、设计科学合理，使用方便，在整个吊装过程中，利用全站仪监测各个点位的数据，减小累计误差，确保结构整体线性一致；钢构件会由于温度高低而热胀冷缩，合龙过程中需要进行严密的气温控制，利用温度阶梯曲线技术控制确保精准合龙；对于复杂的下承式提篮刚性系杆拱桥拱肋安装，尤其是结构复杂的异形拱肋，采用本方法的施工思路，具有较好的适用性。
