Structure for improving arch foot anchoring performance of truss type concrete-filled steel tube arch bridge
The invention discloses a structure for improving arch foot anchoring performance of a truss type concrete-filled steel tube arch bridge, and belongs to the field of concrete-filled steel tube arch bridges. The structure comprises an anchor box, a plurality of main arch steel tubes are inserted into the anchor box in a penetrating manner, a plurality of reinforcing ribs are arranged on the outer side of each main arch steel tube, and the reinforcing ribs are arranged by penetrating through the anchor box. An annular cover plate is arranged on the upper side of the anchor box and arranged on the outer side of the main arch steel pipe in a sleeving mode, an inner threaded pipe is arranged on the lower side of the annular cover plate and rotationally installed on a top plate of the anchor boxthrough a limiting sliding ring, an outer threaded pipe is fixed to the bottom wall of the annular cover plate, and the outer threaded pipe and the inner threaded pipe are installed in a threaded mode. A plurality of sleeves are further fixed to the bottom wall of the anchor box. According to the arch bridge arch foot anchoring structure, stable anchoring of the arch foot can be achieved, the structure form is simpler, safety and stability are achieved after anchoring, connecting points in the anchoring box can be prevented from being corroded by air and rainwater, and safety and reliabilityare achieved.
本发明公开了一种改善桁式钢管混凝土拱桥拱脚锚固性能结构，属于钢管混凝土拱桥领域，包括锚箱，所述锚箱内贯穿插设有多个主拱钢管，且每个主拱钢管的外侧均设有多个加强筋，所述加强筋通过贯穿锚箱设置，所述锚箱的上侧设有环形盖板，所述环形盖板套设在主拱钢管的外侧，所述环形盖板的下侧设有内螺纹管，所述内螺纹管通过限位滑环转动安装在锚箱的顶板上，所述环形盖板的底壁上固定有外螺纹管，所述外螺纹管与内螺纹管螺纹安装，所述锚箱的底壁上还固定有多个套管。本方案的拱桥拱脚锚固结构可实现拱脚的稳定锚固，结构形式更加简单，锚固后安全稳定，锚箱内的连接点可避免被空气和雨水腐蚀，安全可靠。
