Root-shaped arch foot structure of concrete-filled steel tube tied arch bridge
The invention discloses a concrete filled steel tube tied arch bridge root type arch springing structure which comprises a concrete skewback and an arch springing steel tube, an arc-shaped stiffening rib plate is arranged on the inner surface of a straight wall plate of the arch springing steel tube, and end sealing plates are arranged at the two ends of the arc-shaped stiffening rib plate, so that a cavity is formed; one end of the arch foot steel pipe is embedded into a concrete skewback of the tied-arch bridge, a ventilation hole is formed in a straight wall plate of the exposed part of the arch foot steel pipe, and a ventilation hole cover plate is arranged at the ventilation hole; a front-end bearing plate is arranged at the junction of the arch foot steel pipe and the concrete skewback; a U-shaped connecting rib is arranged on the outer surface of the arch foot steel pipe; a core concrete layer is arranged in the arch foot steel pipe, a reinforcement cage is arranged in the core concrete layer, and one end of the reinforcement cage is scattered and anchored in the concrete skewback; the device is stable in structure, reliable in anchoring, uniform in force transmission and capable of effectively inhibiting crack development of the arch foot wrapping concrete.
本发明公开了一种钢管混凝土系杆拱桥根型拱脚结构，包括混凝土拱座和拱脚钢管，所述拱脚钢管的平直壁板的内表面设置有弧形加劲肋板，弧形加劲肋板的两端设置有封端板，从而形成空腔；所述拱脚钢管的一端埋入系杆拱桥的混凝土拱座中，拱脚钢管外露部分的平直壁板上开设有通风孔，通风孔处设置有通风孔盖板；所述拱脚钢管与混凝土拱座交界处设置有前端承压板；所述拱脚钢管的外表面设置有U形连接筋；所述拱脚钢管内设置有核心混凝土层，核心混凝土层内设置有钢筋笼，钢筋笼的一端散锚于混凝土拱座内；本发明结构稳定，锚固可靠，传力均匀，可有效抑制拱脚外包混凝土裂缝开展。
