Steel pipe net frame pedestrian pipeline bridge

Abstract

The invention discloses a steel pipe net frame pedestrian pipeline bridge. The steel pipe net frame pedestrian pipeline bridge comprises a bridge body which comprises a pedestrian bridge deck system upper layer and a pipeline or and maintenance channel lower layer; a bridge main beam is of a tubular net frame structure; a steel pipe net frame serves as the main beam; the main beam is formed by the standard length of steel pipe net frame structure and belongs to the modular design and the mass machining and manufacturing can be achieved; the internal space of the steel pipe net frame is large and accordingly the upper and lower separation of pedestrians and a pipeline is implemented, the respective independent space is ensured, and the use and the management are convenient; the steel pipe net frame is high in stiffness and high in bearing capacity and accordingly the steel pipe net frame is suitable for the river crossing requirements of the dense traffic and large pipelines; the net frame is novel in structure and strong in construction sense and accordingly the net frame is suitable for high landscape requirements of bridge sites; different numbers of sections and spans can be selected according to the actual situation to meet the river crossing length requirements; the bridge sharing of the pedestrians and the pipeline is implemented, the respective space is ensured, and the mutual interference is avoided; a canopy is convenient to arrange due to the net frame structure and accordingly the use comfort is improved; the structure is attractive in appearance and accordingly the steel pipe net frame pedestrian pipeline bridge can serve as an urban landscape bridge; the modular design is achieved through the main beam and accordingly the machining and the installation are facilitated; the steel pipe net frame structure can also serve as a special pedestrian bridge main beam to meet the landscape requirements.

Description

technical field [0001] The invention relates to a pedestrian pipeline bridge, in particular to a steel pipe network frame pedestrian pipeline bridge. Background technique [0002] Under normal circumstances, urban pipelines and pedestrian crossings use separate passages or use vehicle bridge passages. However, bridge site resources are limited, and in order to reduce the impact of the project on the environment, pedestrians and pipelines can share the bridge to cross the river. Existing pedestrian and pipeline shared bridges are generally concrete girder bridges or steel truss bridges. The concrete girder bridge scheme means that pedestrians and pipelines are located on the same bridge deck, pedestrians' sight is blocked, the comfort of use is poor, pipelines and pedestrians are not completely separated, and the safety of pedestrians and pipelines is not suitable for protection. For the steel truss beam scheme, pedestrians and pipelines are layered, pipelines are located i...

Problems solved by technology

Although these two schemes realize the function of pedestrians and pipelines crossing the river, they have poor landscape and cannot meet the increasingly high requirements of urban construction for bridge landscape.

At the same time, human needs are not considered, and suitable sunshade and rain shelter facilities are not provided for pedestrians. Humanized design should be considered for long pedestrian bridges in cities.
