Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a composite functional bridge main beam section structure. Background Art

[0002] When multiple crossing demands appear at the same time, it is an efficient and economical approach to integrate multiple functions and build bridges with composite functions in line with the concept of green intensiveness. While carrying out functional integration, the mutual influence between traffic, pipelines and landscape should be fully considered. The integration of bridge landscape and traffic functions is often easier to achieve. When the pipelines are integrated, especially the integration of multiple and large pipelines at the same time, it will have a greater impact on the bridge landscape. Measures need to be taken to minimize pipeline leakage. The box-shaped main beam of the bridge can accommodate some pipelines that have little impact on each other. When the impact between pipelines is more prominent, such as water and electricity pipelines, there will be greater safety hazards if they are placed in the box at the same time. Therefore, the water and electricity pipelines need to be arranged separately outside and inside the box. At the same time, the water pipeline should be placed outside the box considering leakage.

[0003] In summary, for bridges that integrate transportation, pipelines and landscape functions, intensive use of bridge resources can be made, saving construction costs; for bridges with complex functional requirements, it is necessary to take structural measures to reduce the mutual influence between pipelines, pipelines and transportation, and pipelines and bridge landscapes. This patent will propose a set of reasonable and feasible cross-section layout plans for complex functional bridge structures. Summary of the invention
