UHPC-UHPC wet joint structure with excellent bending and tension resistance and pouring method
The invention belongs to the technical field of segmented pouring bridges, and discloses a UHPC-UHPC wet joint structure with excellent bending resistance and a pouring method.The UHPC-UHPC wet joint structure is characterized in that a first UHPC pouring section and a second UHPC pouring section are connected through two opposite wet connection interfaces, a wet joint is formed at the joint of the first UHPC pouring section and the second UHPC pouring section, and a reinforcing cover layer is glued to the wet joint; the wet connection interface of the UHPC pouring section I is a scabbled wet connection interface; a plurality of initial anchoring steel bars are arranged at the wet joint, penetrate through the wet joint interface and are anchored in the pouring space, and a plurality of reinforcing steel bars are welded/bound on the initial anchoring steel bars. According to the technical scheme, operation is easy, the reinforcing effect on the wet connection interface is obvious, particularly, by adopting the UHPC wet joint structure, the wet connection UHPC structure with discontinuous pouring can be calculated according to the overall UHPC structure, and great convenience is brought to design.
本发明属于分段浇筑桥梁技术领域，并公开了一种抗弯拉能力优异的UHPC‑UHPC湿接缝构造及浇筑方法，包括：UHPC浇筑段一和UHPC浇筑段二通过相对的两个湿接界面连接，UHPC浇筑段一和UHPC浇筑段二的连接处构成湿接缝，湿接缝上胶接有加强盖层；UHPC浇筑段一的湿接界面为凿毛处理后的湿接界面；湿接缝处设置有若干初始锚固钢筋，初始锚固钢筋穿过湿接界面锚固于浇筑空间中，且均焊接/绑扎有若干加强钢筋。本发明技术方案操作简单，对湿接界面加固效果明显，特别是通过采用本UHPC湿接缝构造，能够将浇筑不连续的湿接UHPC结构按整体UHPC结构进行计算，给设计带来极大便利。
