Embodiment 1

[0052] Such as Figure 1-3 , Figure 10-12 , Figure 16-18 Shown, a kind of cable-stayed bridge of the present invention adopts the structural arrangement of single tower double cable plane, mainly comprises auxiliary pier 1 and bridge end 5, and cable-stayed bridge auxiliary pier 1 and bridge end 5 are used as supporting cable-stayed bridge auxiliary pier fulcrum, supports The entire Leaning Tower Bridge. In order to improve the stiffness of the main span, the auxiliary pier 1 is arranged inside the side span. The auxiliary pier 1 is made of reinforced concrete to ensure the stability of the pier structure; because the force of the auxiliary pier 1 is relatively complicated, especially when the active load Under the action, the auxiliary pier 1 may bear a relatively large vertical uplifting force, but cannot bear the horizontal force, so the present invention provides a tensile support on the structural setting of the auxiliary pier 1 . The bridge end 5 is used as the main...

Abstract

The invention discloses a construction method of a cable-stayed bridge, which mainly solves the problems in the prior art that the bridge body is large in weight, and the material consumption is largeand the cost is high. The cable-stayed bridge adopts the form of single pylon and double cable planes, and the main girder is directly pulled on the pylon by a plurality of stay cables, and the staycables replace the multi-span elastic support continuous girder of the pier, so that the problems existing in the prior art can be overcome, the building height can be reduced, the weight of the structure can be lightened, the material can be saved, and the bridge has good popularization and utilization value.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a construction method of a cable-stayed bridge. Background technique [0002] Cable-stayed bridges, also known as cable-stayed bridges, can be divided into steel cable-stayed bridges, combined beam cable-stayed bridges and concrete beam cable-stayed bridges according to the different materials used for the beams. The cable-stayed bridge is mainly composed of cable towers, main girders, and cable-stayed cables. It is a bridge in which the main girder is directly pulled on the bridge tower with many cables. A structural system composed of beams and bodies. A cable-stayed bridge is a self-anchored system in which the horizontal forces of the cables are borne by the girders. In addition to being supported on the pier, the beam is also supported on the stay cables drawn from the tower columns. [0003] Existing cable-stayed bridges are generally equipped with multiple cable towers, which are...
