Embodiment Construction

[0015] The invention relates to the application of a trestle-type girder-slab bridge in inland rivers with tidal flats on both banks.

[0016] The application of the trestle-type girder-slab bridge in inland rivers with tidal flats on both banks includes:

[0017] Pile driving operation starts from one side of the river. After the construction of the first four rows of pile foundations is completed, a temporary construction steel platform is installed above the completed pile foundation, and subsequent piling operations are carried out on the temporary construction steel platform; The forward cycle of the platform is carried out until the other side of the river is fully completed; the removal of the temporary construction steel platform; and

[0018] Pile girder installation and bridge deck construction; after the piling operation equipment advances to a station, the crawler crane stands on the temporary construction steel platform to hoist the steel structure box girder and ...

Abstract

The invention relates to bridge construction, in particular to an application of a trestle type bridge. An application of a trestle type beam slab bridge in an inland river with beaches at the both sides comprises the following step of carrying out piled beam installation, bridge floor construction and piling operation in the water flow. The invention has the beneficial effect that when a trestle method is used for carrying out bridge construction on the inland river with the beaches at the both sides, the requirements on vegetation and fish protection can be satisfied.

Description

technical field [0001] The invention relates to a bridge construction, in particular to the application of a trestle bridge. Background technique [0002] At present, bridge construction commonly adopts forms such as cable-stayed bridges, suspension bridges, girder bridges, and arch bridges. In urban construction, cable-stayed bridges and suspension bridges have been widely used in urban construction in recent years. For field construction, there are often tidal flats on both sides of the river, and there are many restrictions on the construction of bridges on inland rivers. For example, some rivers need to pass ships, some need to ensure the water supply of downstream vegetation, and some need to ensure the fish in the river The swimming is disturbed as much as possible. As a result, many forms cannot be used, in which case girder-slab bridges are a good choice, but there are still limitations to consider during construction. Contents of the invention [0003] The pres...
