Construction method of large-span Y-shaped steel box rib arch bridge
The invention discloses a construction method of a large-span Y-shaped steel box rib arch bridge. The construction method comprises the steps that a segment prefabricating yard is built; assembling a bridge prefabricated steel structure in the segment prefabricating field to obtain various types of to-be-hoisted segments; numbering each section of a bridge main arch rib of the large-span Y-shaped steel box rib arch bridge; according to the serial number of each section of the bridge main arch rib, each preset hoisting position is obtained; according to the types of the to-be-hoisted segments, hoisting the to-be-hoisted segments to the hoisting positions matched with the to-be-hoisted segments in batches; and closure is conducted on the various types of hoisting sections, and the large-span Y-shaped steel box rib arch bridge is formed. According to the construction method of cable hoisting, various to-be-hoisted sections are hoisted in batches, the height of the tower is reduced, the construction cost is reduced, the construction difficulty is reduced, the safety in the construction process of the large-span Y-shaped steel box rib arch bridge is guaranteed, and reference is provided for similar projects similar to the large-span Y-shaped steel box rib arch bridge.
本发明公开了一种大跨径Y型钢箱肋拱桥施工方法，包括：建设节段预制场；在所述节段预制场内拼装桥梁预制钢结构，获得多种类型的待吊装节段；将所述大跨径Y型钢箱肋拱桥的桥梁主拱肋的各节段进行编号；根据所述桥梁主拱肋的各节段编号，获得各预设吊装位；根据所述待吊装节段的类型，分次将各所述带吊装节段吊装至与之匹配的所述吊装位；对各类型的所述吊装节段进行合龙，形成所述大跨径Y型钢箱肋拱桥。本发明采用缆索吊装的施工方法，分次吊装各类型的待吊装节段，减小了塔架的高度，降低工程造价，降低了施工难度，保障了大跨径Y型钢箱肋拱桥施工过程中的安全性，且为与大跨径Y型钢箱肋拱桥近似的同类工程提供了参考。
