Arch bridge arch foot foundation structure, construction method thereof and arch bridge
The invention provides an arch bridge arch foot foundation structure, a construction method thereof and an arch bridge, and relates to the technical field of bridge construction. The construction method of the arch bridge arch foot foundation structure comprises the steps of site leveling, pipe shed construction, foundation pit excavation, foundation construction and skewback construction. The site leveling step comprises: determining the intersection of the arch axis and the hillside, and excavating the platform. The pipe shed construction step comprises: arranging a pipe shed supporting structure at the excavated hole. The foundation construction step comprises: forming a foundation in foundation pit construction. The skewback construction step comprises: forming a skewback on the foundation through construction, and connecting the skewback with arch feet. The arch bridge arch foot foundation structure comprises the skewback and the foundation, and the skewback is fixedly connected with the foundation. The area of the surface, close to the foundation, of the skewback is smaller than that of the surface, close to the skewback, of the foundation. The foundation is used for being buried in a mountain, and the skewback is used for being connected with arch feet. The arch bridge comprises arch feet and the skewback foundation structure of the arch bridge, and the arch feet are connected with the skewback. During excavation, a pipe shed supporting structure is arranged, open excavation is changed into underground excavation, and slope excavation is reduced.
本申请提供了一种拱桥拱脚基础结构及其施工方法及拱桥，涉及桥梁建设技术领域。拱桥拱脚基础结构的施工方法包括场地平整、管棚施工、基坑开挖、基础施工和拱座施工几个步骤。场地平整：确定拱轴线与山坡相交处，开挖平台。管棚施工：在开挖洞口设置管棚支护结构。基础施工：在基坑施工形成基础。拱座施工：在基础上施工形成拱座，拱座用于与拱脚连接。拱桥拱脚基础结构包括拱座和基础，拱座与基础固定连接。拱座的靠近基础的表面的面积小于基础的靠近拱座的表面的面积。基础用于埋设在山体中，拱座用于与拱脚连接。拱桥包括拱脚和上述的拱桥拱脚基础结构，拱脚与拱座连接。在开挖时设置管棚支护结构，实现由明挖转变为暗挖，减少边坡开挖。
