Embodiment Construction
[0024] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:
[0025] Such as Figure 1~2 As shown, a cable-stayed bridge with semi-floating truss-type pylons includes side piers 3 on both sides and a bridge tower 2 in the middle, and supports 4 are provided at the middle of the bridge tower 2 and the upper ends of the side piers 3, so that A main girder 5 that directly bears the load of the bridge deck is arranged on the support 4 , multiple pairs of stay cables 6 are arranged between the bridge tower 2 and the main girder 5 , and the bridge tower 2 is separated from the main girder 5 .
[0026] The bridge tower 2 is a truss type bridge tower with integrated tower pier and separated tower beams.
[0027] The pylons 2 are A-shaped in the longitudinal direction, and the pylons 2 are H-shaped in the transverse direction.
[0028] The support 4 is a longitudinal movable support and a two-way movable support, and two rows of s...
