Arch foot structure of arch bridge
The invention relates to the field of bridge structures, in particular to an arch foot structure of an arch bridge, which comprises a profile body, a spiral rib, an anchoring plate, an end anchoring plate and an arch rib piece, a plurality of through holes are formed in the profile body in the length direction, the spiral rib transversely penetrates through the through holes, and therefore transmission of internal force from the arch rib piece to the arch rib of the profile body is achieved; after concrete is poured, the spiral ribs can effectively restrain the skewback concrete around the sectional material main body, so that the concrete in the area is always in a multidirectional compression state, and the local pressure bearing capacity of the skewback concrete is improved; the sectionbar main body outer wrapping concrete and the arch support concrete are poured in the same batch, the problem of concrete cracking caused by pumping pressure and hydration heat of concrete in a pipeand pressure-bearing stress concentration of the end of a steel pipe can be fundamentally avoided, the structural mechanical property is optimized, and the arc foot structure has the advantages of being convenient to install, easy to use, good in economical efficiency and the like.
本发明涉及桥梁结构领域，具体为一种拱桥拱脚结构，包括型材主体、螺旋筋、锚固板、端锚板及拱肋件，所述型材主体沿着长度方向设置有多个通孔，所述螺旋筋横向穿过通孔，从而实现拱肋件到型材主体拱肋内力的传递，浇灌混凝土后，螺旋筋能有效约束型材主体周围的拱座混凝土，使该区域混凝土始终处于多向受压状态，从而提高拱座混凝土的局部承压能力；型材主体外包混凝土与拱座混凝土同批浇筑，可以从根本上避免管内混凝土泵送压力、水化热导致、钢管端部承压应力集中导致的混凝土开裂问题，优化了结构力学性能，具有安装方便、使用简单、经济性好等特点。
