Construction method of overwater large-span double-layer cast-in-place beam
The invention discloses a construction method of an overwater large-span double-layer cast-in-place beam. According to the method, a supporting structure is adopted for overwater large-span double-layer cast-in-place beam construction, and two-time vertical rotation of a steel inclined strut is achieved through a hinge system. The method guarantees that: a double-layer cast-in-place main beam shares one set of support during construction, temporary support for underwater construction is avoided, the problem of space collision between the supporting column and the cofferdam wall body is solved, and structural safety and quality control points are clearer. The method has the advantages of being convenient to implement, safe and reliable.
本发明是一种水上大跨双层现浇梁施工方法，所述方法采用支撑结构进行水上大跨双层现浇梁施工，通过铰接系统实现钢斜撑的两次竖向转动，保证双层现浇主梁施工时共用一套支撑，避免了水下施工临时支撑，解决了支撑柱与围堰壁体空间碰撞问题，使结构安全和质量控制点更为明确，具有实施便捷，安全可靠的优点。
