UHPC arch ring structure, bridge and construction method thereof
The invention relates to the field of bridge engineering, in particular to a UHPC arch ring structure, a bridge and a construction method of the UHPC arch ring structure, an arch ring comprises a plurality of arch ring sections, every two adjacent arch ring sections are detachably connected, each arch ring section comprises prefabricated UHPC web plates which are symmetrically arranged, and pouring structures are arranged at the upper ends and/or the lower ends of the prefabricated UHPC web plates. Due to the symmetrical arrangement of the prefabricated UHPC web plates, the material consumption is reduced, meanwhile, the structural strength is guaranteed, the lightweight design of the arch ring section is achieved, the transportation and installation cost can be reduced, meanwhile, the UHPC web plates are prefabricated, the construction speed is increased, on-site pouring of the web plates is avoided, the construction progress is accelerated, and the construction period is shortened; the prefabricated UHPC web is matched with the pouring structure, the cost can be reduced while the local strength and durability of the arch ring section are improved, and the problem that the cost is too high due to the fact that the whole arch ring section is made of UHPC materials is solved.
本发明涉及桥梁工程领域，具体涉及一种UHPC拱圈结构、桥梁及其施工方法，拱圈包括若干个拱圈段，相邻两个所述拱圈段为可拆卸连接，所述拱圈段包括对称设置的预制UHPC腹板，所述预制UHPC腹板上端和/或下端均设有浇筑结构，预制UHPC腹板的对称设置减少了材料用量，同时保证了结构强度，实现了拱圈段的轻量化设计，有助于降低运输和安装成本，同时UHPC腹板采用预制式，加快了施工速度，避免现场对腹板进行浇筑，加快了施工进度，缩短了施工周期；本发明通过将预制UHPC腹板与浇筑结构进行搭配，能在提升拱圈段局部强度与耐久度的同时，降低成本，避免拱圈段通体使用UHPC材料，导致成本过高的问题。
