Steel-concrete combined skewback structure suitable for multi-span basket arch bridge and construction method of steel-concrete combined skewback structure
The invention belongs to the technical field of arch bridge structures, and particularly relates to a steel-concrete combined skewback structure suitable for a multi-span basket arch bridge and a construction method of the steel-concrete combined skewback structure. By arranging the lower single reinforcing mesh unit, the upper ring reinforcing mesh unit, the framework inner concrete block and the framework outer concrete block on the closed annular steel framework unit, 1, the lower single reinforcing mesh unit and the upper ring reinforcing mesh unit are arranged on the lower single reinforcing mesh unit and the upper ring reinforcing mesh unit, and the framework outer concrete block is arranged on the lower single reinforcing mesh unit and the upper ring reinforcing mesh unit; a proper reinforcing mesh size can be selected according to the difference between the outer contour size of the skewback and the size of the closed ring-shaped steel skeleton unit, so that a sufficient steel structure supporting and reinforcing effect can still be achieved at a relatively large skeleton outer concrete block; 2, the upper reinforcing mesh unit with the ring and the closed ring-shaped steel skeleton unit can reinforce and mount the arch rib pipe together, so that the arch rib pipe has enough structural stability on the skewback;
本发明属于拱桥结构技术领域，尤其涉及一种适用于多跨提篮拱桥的钢混组合拱座结构及其施工方法。本发明通过在封闭环状钢骨架单元上设置下部单钢筋网单元、上部带圈钢筋网单元、骨架内混凝土块，以及骨架外混凝土块的方式，使得：1、下部单钢筋网单元和上部带圈钢筋网单元，可以根据拱座外轮廓尺寸和封闭环状钢骨架单元尺寸之间的差距，选定合适的钢筋网尺寸，保证即使是相对较大的骨架外混凝土块处仍然具有充分的钢结构支撑加固效果；2、上部带圈钢筋网单元和封闭环状钢骨架单元可以一起加固安装拱肋管，保证拱肋管在拱座上具有足够的结构稳定性。
