Creeping formwork construction method for sea-crossing cable tower bridge main tower
The invention relates to a creeping formwork construction method for a sea-crossing cable tower bridge main tower, and belongs to the technical field of creeping formwork construction.The creeping formwork construction method comprises the steps that firstly, when a first layer of steel bars of the main tower are bound, needed embedded parts are embedded, first layer of concrete of the main tower is poured, and after the strength of the concrete of the main tower reaches the standard, formwork removal is conducted, and wall attaching devices are installed at the embedded parts of the first layer of the main tower; secondly, a truss is assembled, the assembled truss is hoisted and hung on a wall attaching device which is buried when a first layer of the main tower is poured, embedded parts are positioned and installed on formworks, the formworks are assembled, a second layer of concrete of the main tower is poured, and a third layer of steel bars is bound; thirdly, after the concrete strength of the main tower reaches the standard, the formwork is removed, the formwork is moved backwards, a wall attaching device and a hoisting guide rail are installed at the embedded part, a hydraulic system is established, and a synchronous climbing monitoring system is arranged on the hydraulic system; fourthly, the hydraulic system climbs, and meanwhile it is guaranteed that the truss and the formwork are synchronously lifted through a hydraulic synchronous climbing monitoring system; the positioning accuracy is high.
本发明涉及一种跨海索塔桥主塔用爬模施工方法，属于爬模施工技术领域，步骤一：在绑扎主塔第一层钢筋时，同时预埋所需的预埋件，浇筑主塔第一层混凝土，主塔混凝土强度达标后，拆模且在主塔第一层的预埋件处安装附墙装置；步骤二：拼装桁架，将拼好的桁架吊起，挂于主塔第一层浇筑时埋好的附墙装置上，在模板上定位安装预埋件，合模，浇筑主塔第二层混凝土，绑扎第三层钢筋；步骤三：主塔混凝土强度达标后拆模，后移模板，在预埋件处安装附墙装置，吊装导轨，建立液压系统，并在液压系统上设置同步爬升监测系统；步骤四：液压系统爬升，同时利用液压同步爬升监测系统确保桁架和模板在同步提升；其定位准确性高。
