Arch rib concrete filled steel tube reinforcing method based on rib arch bridge
The invention relates to the technical field of rib arch bridges, in particular to an arch rib concrete filled steel tube reinforcing method based on a rib arch bridge, which comprises the following steps: S1, pouring pile foundation concrete on an arch support foundation; s2, stiff frameworks are symmetrically arranged on the two banks and are closed; s3, steel pipe concrete is poured in the framework; and S4, after the concrete in the framework reaches the design strength, arch ring concrete is poured from the two banks in a symmetrical mode till closure is achieved. The pile foundation concrete is used for bearing the skewback foundation and the reinforcing part; the steel pipe concrete is used for enhancing the stiff framework and enabling the stiff framework to reach the design strength; the arch ring concrete is used for reinforcing the two sides and the bottom of the arch bridge. The pile foundation concrete bears the skewback foundation and the reinforcing part, and the stiff framework bears the bridge abutment, so that the situation that the bridge abutment and the skewback foundation settle or slide towards the side of a main span due to unfavorable geology is avoided, the rib arch bridge is reinforced, and the problems of support shifting, complete disengaging or shear overrun and local cracking of the bridge abutment, the skewback and an arch ring are solved.
本发明涉及肋拱桥技术领域，具体是指一种基于肋拱桥的拱肋钢管混凝土加固方法，包括S1、在拱座基础上浇筑桩基混凝土；S2、两岸对称设置劲性骨架并合龙；S3、在骨架内浇筑钢管混凝土；S4、骨架内的混凝土达到设计强度后，从两岸对称方式浇筑拱圈混凝土，直至合龙。本发明通过桩基混凝土用于承载拱座基础和加固部；钢管混凝土用于增强劲性骨架并使劲性骨架达到设计强度；拱圈混凝土用于对拱桥两侧和底部进行加固。通过桩基混凝土承载拱座基础和加固部，劲性骨架承载桥台，避免了不良地质引起桥台、拱座基础沉降或向主跨侧滑移，加固了肋拱桥，解决了支座串动、完全脱空或剪切超限，桥台、拱座、拱圈局部开裂的问题。
