Construction method for consolidation system cable-stayed bridge steel-concrete combined section
The invention provides a construction method for a consolidation system cable-stayed bridge steel-concrete combined section. The method comprises the following steps: pouring a lower tower column, pre-embedding an anchor beam support frame in the lower tower column, arranging an anchor beam inserted with a steel strand on the anchor beam support frame, and carrying out secondary pouring; completing pouring of the lower tower column, inserting the lower tower column into the cast-in-place beam, and stopping pouring at the position 30-50 cm away from the top of the cast-in-place beam; covering the surface of the cast-in-place beam formed through the secondary pouring with a steel plate, and arranging a stiff framework on the steel plate, wherein one end of the stiff framework is fixed perpendicular to the steel plate, and the other end of the stiff framework extends to the top of the upper tower column; and after the stiff framework is arranged, performing third-time pouring so as to complete the construction of the consolidation system cable-stayed bridge steel-concrete combined section; The construction method has the beneficial effects that: smooth construction is guaranteed through double measures of layered pouring and arrangement of the stiff framework, the structural stress condition of the joint of the steel-concrete joint sections is improved, and the method has the advantages of being high in operability and easy to construct.
本发明提供了一种固结体系斜拉桥钢混结合段施工方法，包括以下步骤：浇筑下塔柱，在下塔柱内预埋锚梁支撑架，将穿插有钢绞线的锚梁设置于锚梁支撑架上，进行第二次浇筑；完成下塔柱的浇筑，且下塔柱插入现浇梁内，在距离现浇梁的顶部30‑50cm处，停止浇筑；在第二次浇筑形成的现浇梁表面覆盖钢板，并在钢板上设置劲性骨架，劲性骨架的一端垂直于钢板固定，劲性骨架的另一端延伸至上塔柱的顶部；待设置完劲性骨架，进行第三次浇筑完成固结体系斜拉桥钢混结合段的施工；本发明的有益效果为：本发明所述的施工方法通过分层浇筑和设置进行劲性骨架双重措施保证施工顺利进行，改善了钢混结合段结合处结构受力情况，具有操作性强、施工简单的优点。
