Bi-directional traction vertical rotation construction method for cable-stayed bridge steel arch tower
The invention relates to a bridge construction method, specifically to a bi-directional traction vertical rotation construction method for a cable-stayed bridge steel arch tower. The bi-directional traction vertical rotation construction method for the cable-stayed bridge steel arch tower comprises the following construction steps: 1) assembly construction: (1) vertical rotation hinge installation; (2) steel box girder installation; (3) steel arch tower installation; (4) vertical rotation frame assembly; (5) hang cable and vertical rotation frame positioning; 2) rotator construction: pulling a rear pull cable (18) to entirely pull the steel arch tower (1), while the cable force of the rear pull cable (18) is reduced under the safe cable force, synchronously extending and pulling a balance cable (21) to ensure that the cable force of the rear pull cable (18) is not less than the safe cable force, and continuously rotating; after rotating the steel arch tower (1) to be in place, welding to form a whole body at the fracture position; and detaching a steel arch tower assembly moulding bed (10), a vertical rotation hinge (4), a stable cable (25) and a stable cable connector (26), and finishing the installation. The goal of safely constructing, improving the project quality, shortening the construction period, and saving the construction cost can be achieved by optimizing and innovating the construction method.
