Bridge expansion joint repairing structure based on ultra-high performance concrete UHPC application
The invention discloses a bridge expansion joint repairing structure based on ultra-high performance concrete UHPC application, and belongs to the technical field of expressway maintenance and protection. The bridge expansion joint repairing structure comprises bridge bodies, an expansion joint is formed in a gap between the two bridge bodies, and a mounting groove is formed in the side, close to the expansion joint, of each bridge body; a plurality of supporting frames are installed in the installation groove side by side in the axis direction of the installation groove, a first reinforcing mesh is fixedly installed on the supporting frames and is formed by connecting a plurality of square steel in a shape like a Chinese character'tian ', through holes for concrete to pass through are formed between the square steel, and a second reinforcing mesh is slidably installed on the bottom side of the first reinforcing mesh. The through holes of the first reinforcing mesh can be opened or closed by sliding the second reinforcing mesh, steel fiber concrete S-UHPC is poured on the bottom side of the first reinforcing mesh, and polyformaldehyde fiber concrete P-UHPC is poured on the top side of the first reinforcing mesh. After two layers of concrete are coagulated, the layering position is more regular, and repairing is more uniform.
本发明公开了一种基于超高性能混凝土UHPC应用的桥梁伸缩缝修补结构，属于高速公路养护与防护技术领域，包括：桥梁本体，两个桥梁本体之间的间隙形成伸缩缝，桥梁本体靠近伸缩缝侧设有安装槽，安装槽内沿安装槽的轴线方向并排安装有若干个支撑架，支撑架上固定安装有第一钢筋网，第一钢筋网由多个方形钢成田字形连接而成，方形钢之间形成用于混凝土通过的通孔，第一钢筋网底侧滑动安装有第二钢筋网，滑动第二钢筋网能够使第一钢筋网的通孔打开或封闭，第一钢筋网底侧浇筑有钢纤维混凝土S‑UHPC，第一钢筋网顶侧浇筑有共聚甲醛纤维混凝土P‑UHPC。本发明使两层的混凝土凝结后，分层处更加规则，使修复更均匀。
