Embodiment Construction

[0049] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0050] Aiming at the special structure of the cable-stayed bridge with single inclined tower and single cable plane mixed girder, the present invention provides a synchronous bridge forming process of tower, beam and cable. The construction of the cast-in-place support of the beam and the tensioning construction of the cable-stayed cables are carried out simultaneously.

[0051] The cable-stayed bridge with single-cable-plane hybrid girders and single-cable plane, the steel box girder structure of the main span is constructed by cantilever assembly technology, the height of the cable tower is high and the angle of inclination is large, and it cannot be independent and self-stabilized during the construction process. The cantilever is carried out...

Abstract

The invention discloses a tower, beam and cable synchronous bridge forming technology. According to the technology, main tower creeping formwork construction, steel box beam cantilever assembly, side span concrete box beam cast-in-place support construction and stay cable and hung cable stretch-draw construction are conducted alternately and synchronously. The tower, beam and cable synchronous bridge forming technology achieves safe and reliable full-bridge construction.

Description

technical field [0001] The invention relates to a building construction technology, in particular to a bridge construction technology. Background technique [0002] Cable-stayed bridge, also known as cable-stayed bridge, is a bridge in which the main girder is directly pulled on the bridge tower by many cables. structural system. It can be regarded as a multi-span elastically supported continuous beam with cables instead of piers. It can reduce the bending moment in the beam body, reduce the height of the building, reduce the weight of the structure, and save materials. A cable-stayed bridge consists of a cable tower, a main girder, and a cable-stayed bridge. [0003] As a cable system, the cable-stayed bridge has a larger spanning capacity than the girder bridge, and is the most important type of long-span bridge. The cable-stayed bridge is a bridge deck suspended by many steel cables directly connected to the tower, and the cable-stayed bridge is composed of a cable to...
