Bridge main tower cross beam construction method
The invention provides a bridge main tower cross beam construction method, which belongs to the technical field of bridge construction, and comprises the following steps: in the construction process of a lower tower column, synchronously designing, processing and manufacturing a lower cross beam bracket, embedding an embedded part, erecting the lower cross beam bracket and processing a template, and performing lower cross beam reinforcing steel bar and prestress construction on the bracket. Then, lower cross beam formwork installation, lower cross beam concrete construction, lower cross beam prestress construction, tower column segmental construction to the upper cross beam, upper cross beam support installation, upper cross beam reinforcing steel bar and prestress construction, upper cross beam formwork installation, upper cross beam concrete construction and upper cross beam prestress construction are conducted, and the tower columns continue to be constructed to the tower top; construction of a top section is completed, top sealing of the tower column is achieved, and formwork removal treatment is conducted. The upper cross beam and the lower cross beam are subjected to concrete pouring twice, and a tower-beam asynchronous construction mode is adopted, so that the construction efficiency can be greatly improved, the construction period can be shortened, the equipment leasing time can be shortened, the cost can be reduced, and the construction safety is higher.
本发明提供一种桥梁主塔横梁施工方法，属于桥梁施工技术领域，方法包括如下步骤：在下塔柱施工过程中，同步进行下横梁支架的设计、加工制作、预埋件埋设、下横梁支架搭设和模板加工，在支架上进行下横梁钢筋及预应力施工，然后进行下横梁模板安装，下横梁混凝土施工，下横梁预应力施工，分节段施工塔柱至上横梁处，安装上横梁支架，上横梁钢筋及预应力施工，上横梁模板安装，然后上横梁混凝土施工，最后上横梁预应力施工，继续施工塔柱至塔顶，完成顶节的施工，实现塔柱封顶，并进行拆模处理。上下横梁分两次进行混凝土浇筑，并均采用塔梁异步施工方式，可以大大的提高施工的效率，缩短工期，可以减少了设备的租赁时间，降低成本，施工安全性更高。
