Construction craft: 1 hanging basket hanging void, at this point the anti force downward force to the hanging beam hanging basket, hanging basket and the longitudinal beams under negative bending moment. 2 hanging basket forward, hanging basket still bear negative moment, a single arm state. 3 hanging basket beam lifting, after anchorage anchorage, the hanging basket is in place, after the anti point elevation roughly leveling, set preraised height. The 4 cable is connected with the hanging basket, and the first cable tension is carried out, and the front pivot point of the hanging basket is stressed. 5 to the 1/2 beam section for the second cable tension. When the concrete beam of the 6 section is completely cross section, the elasticity of the end of the basket is less than the specified value. 7 detect the beam elevation, the concrete strength to reach the tension of prestressed beam. 8 hanging basket to be moved forward.
With the development of material science and computer science, a lot of cable-stayed bridges have been built at home and abroad since the Stromsun bridge in 1956 started the apex of modern cable-stayed bridge. The cable-stayed bridge has been developed rapidly because of its advantages such as large span, good structural performance, simple construction, easy maintenance, low cost and attractive appearance.
The hanging basket construction, large span cable-stayed bridge construction process 1 overview 1.1 definition of cable-stayed bridge is a bridge deck system of compression, tension support system, the system of the stiffening girder deck structure, its supporting system composed by cable.
