Construction method for lower chord beam of an arched beam combined type continuous rigid frame bridge
The invention belongs to the technical field of bridge construction, and particularly relates to a construction method for a lower chord beam of an arched beam combined type continuous rigid frame bridge. The construction method comprises the steps that the hanging basket is hung on the lower chord beam; and the hanging basket is controlled to walk on the lower chord beam, and pouring work of allsections of the lower chord beam is completed in sequence. The construction space of the lower step of the lower chord beam can be effectively utilized, the problems of cracking and down warping caused by the fact that the upper chord beam does not have enough bearing capacity can also be avoided, and good popularization space is achieved.
本发明属于桥梁施工技术领域，尤其涉及一种拱梁组合式连续刚构桥下弦梁施工方法。该施工方法包括：将挂篮悬挂在下弦梁上；控制挂篮在下弦梁上行走，依次完成下弦梁的各个节段的浇注工作。本发明可以有效利用下弦梁下步的施工空间，也可以避免因上弦梁不具有足够的承载力，造成的开裂和下挠问题，具有很好的推广空间。
