Space Y-shaped steel box arch bridge construction method
The invention discloses a spatial Y-shaped steel box arch bridge construction method. The method comprises the steps that a construction reference model is established; according to the construction reference model, a plurality of main arch rib to-be-assembled segments are symmetrically erected segment by segment, a plurality of auxiliary arch rib to-be-assembled segments are installed on the main arch rib segments so as to form a to-be-lapped area, a temporary support is erected in the to-be-lapped area so as to form a support area on one side of the to-be-lapped area, and a plurality of auxiliary arch rib to-be-lapped areas are formed on the other side of the to-be-lapped area. And the multiple connecting rib sections to be assembled are hoisted in the support area to form a hoisting opening area, the main arch rib main beam sections to be assembled continue to be hoisted in the hoisting opening area, and the spatial Y-shaped steel box arch bridge is formed through assembling. The construction method of cable hoisting is combined with the construction reference model, so that the construction cost is reduced, the construction difficulty is reduced, the construction method is more suitable for the construction process of the spatial Y-shaped steel box arch bridge, the safety in the construction process of the spatial Y-shaped steel box arch bridge is guaranteed, and reference is provided for similar engineering of the same kind.
本发明公开了一种空间Y型钢箱拱桥施工方法，包括：建立施工参照模型；根据所述施工参照模型，逐段对称架设多个主拱肋待拼装节段，在所述主拱肋节段上安装多个所述副拱肋待拼装节段，以形成待搭接区，在所述待搭接区搭设临时支架，以在所述待搭接区的一侧形成支架区域，在所述支架区域内吊装多个所述连接肋待拼装节段，以形成吊装口区域，在所述吊装口区域内继续吊装所述主拱肋主梁待拼装节段，拼装形成所述空间Y型钢箱拱桥。本发明通过采用缆索吊装的施工方法并与施工参照模型相结合，降低工程造价，降低了施工难度，更适用于空间Y型钢箱拱桥的施工过程，保障了空间Y型钢箱拱桥施工过程中的安全性，且为近似的同类工程提供了参考。
