Construction method for steel-concrete combined section of hybrid beam type cable-stayed bridge
The invention belongs to the technical field of cable-stayed bridge construction, and particularly relates to a hybrid beam type cable-stayed bridge steel-concrete combined section construction method which comprises the following steps that a plurality of bridge parts capable of being assembled are prefabricated, and a steel panel used for fully paving a roadbed is installed on the tops of the bridge parts; meanwhile, pouring of the bridge tower is completed, and a plurality of anchor cables with different lengths are prefabricated according to measurement and calculation; a workbench is erected at the bottoms of the bridge pieces and used for installing the two bridge pieces on the inner side of the bridge tower, and anchor cables are connected to the deviating ends of the two bridge pieces; sequentially arranging and mounting along with the step S3 until the bridge piece is closed with another adjacent bridge piece or mounted on a base of a river bank in an extending manner; and monitoring whether various indexes of the bridge member and the connecting part thereof are qualified, and after the indexes are qualified, paving the roadbed. According to the invention, rapid assembly of the bridge body and stress expansion of the bridge floor can be realized.
本发明属于斜拉桥施工技术领域，具体涉及一种混合梁式斜拉桥钢混结合段施工方法，包括如下步骤：预制多个可拼装的桥梁件，以及在桥梁件顶部安装用于通铺路基的钢制面板；同时将桥塔浇筑完成，根据测算，预制多条不同长度的锚索；在桥梁件底部架设工作台，用于安装桥塔内侧的两个桥梁件，并在两个桥梁件的背离端连接锚索；随步骤S3依次设置安装，直至与相邻的另一个桥梁件合龙或延伸安装在河岸的基座；监测桥梁件及其连接部位各项指标是否合格，合格后，通铺路基。本发明，能够实现桥体的快速组装以及桥面的应力伸缩。
