Construction method for positioning arch feet of through type simply-supported basket tied-arch bridge
The invention discloses a construction method for positioning arch feet of a through type simply-supported basket tied arch bridge, which belongs to the technical field of building construction and comprises the following steps: constructing a steel pipe bracket and a distribution beam on a lower beam surface, and marking longitudinal and transverse prestress positions on the distribution beam after the construction is completed; the supporting stand columns are vertically arranged on the distribution beams, the supporting parallel bracings and the supporting inclined struts are evenly arranged on the basis of the supporting stand columns, and the supporting cross beams are installed according to the preset arch foot positions; the arch feet are hoisted to preset positions, the arch feet are fixedly connected with the supporting cross beams, and the two arch feet on the same side are connected by arranging opposite-pulling connecting rods; and inspecting the size of the axis of the arch springing, binding reinforcing steel bars and installing a template after inspection is completed, penetrating prestressed tendons according to longitudinal and transverse prestressed positions, and pouring concrete to complete construction. According to the method, the coordinate positions of the arch feet of the simply supported beam basket type steel pipe arch are more accurately positioned, longitudinal and transverse prestressed tendons of a concrete beam surface are avoided, and pouring is more convenient.
本发明公开了一种下承式简支提篮系杆拱桥拱脚定位的施工方法，属于建筑施工技术领域，包括：施工下部梁面的钢管支架和分配梁，施工完成后在分配梁上标记纵横预应力位置；支撑立柱竖直设置于分配梁上，以支撑立柱为基础均匀设置支撑平联和支撑斜撑，并根据预设拱脚位置安装支撑横梁；吊装拱脚至预设位置，拱脚和支撑横梁固定连接，通过设置对拉连接杆连接同一侧的两个拱脚；检验拱脚轴线尺寸，检验完成后绑扎钢筋和安装模板，并根据纵横预应力位置穿设预应力筋，浇筑混凝土完成施工。本发明更精准的定位了简支梁提篮式钢管拱拱脚坐标位置，并且避开了混凝土梁面的纵横向预应力筋，浇筑更加方便。
