Tower-beam asynchronous construction method of cable-stayed bridge of tower-beam consolidation system
The invention discloses a tower-beam asynchronous construction method of a cable-stayed bridge of a tower-beam consolidation system. The tower-beam asynchronous construction method comprises the following steps of constructing a lower tower column, constructing a tower column of a tower beam consolidation section, and reserving a steel bar joint and a prestressing tendon interface, conducting tension grouting on tower column prestressing tendons of the tower beam consolidation section, enabling the hydraulic creeping formwork to climb, and constructing an upper tower column, erecting a tower beam consolidation section bracket, and constructing the rest part of the tower beam consolidation section. According to the cable-stayed bridge of the tower beam consolidation system, after construction of the lower tower column is completed, the tower column of the tower beam consolidation section is constructed, reinforcing steel bars and prestressing tendon connectors of the tower beam consolidation section (the remaining part) are reserved in the construction process, the hydraulic creeping formwork continues to climb to construct the upper tower column, the creeping formwork is prevented from being dismantled and installed again, and the construction safety risk is reduced.
本发明公开了一种塔梁固结体系斜拉桥的塔梁异步施工方法，其包括步骤：下塔柱施工；塔梁固结段塔柱施工，预留钢筋接头和预应力束接口；塔梁固结段塔柱预应力束张拉压浆；液压爬模爬升，施工上塔柱；搭设塔梁固结段支架；塔梁固结段剩余部分施工。本发明塔梁固结体系的斜拉桥在下塔柱施工完成后，施工塔梁固结段塔柱，施工时预留塔梁固结节段(剩余部分)钢筋、预应力束接口，液压爬模继续爬升施工上塔柱，避免的爬模拆除和再次安装，降低了施工安全风险。
