Circular Structure Prefabricated Pedestrian Bridges in Transportation Junction

Product Specification

Circular Structure Prefabricated Pedestrian Bridges in Transportation Junction Area

Description

Pedestrian bridges are needed where a separate pathway has to be provided for people to cross traffic flows or some physical obstacle, such as a river. The loads they carry are, in relation to highway or railway bridges, quite modest, and in most circumstances a fairly light structure is required. They are, however, frequently required to give a long clear span, and stiffness then becomes an important consideration. The bridges are often very clearly on view to the public and therefore the appearance merits careful attention.

Specification

Design
Design of pedestrian bridge normally follows the same principles as for other bridges. However, because they are normally significantly lighter than vehicular bridges, they are more vulnerable to vibration and therefore dynamics effects are often given more attention in design.
To ensure pedestrian bridges are accessible to disabled and other mobility-impaired people, careful consideration is nowadays also given to provision of access lifts or ramps, as required by relevant legislation.

Features

Provision of suitable access for wheelchairs and cyclists is often specified for pedestrian bridges. Access ramps must be provided and restricted to a maximum gradient. The consequent length of ramps where access is from the level of the road or rail track over which the bridge spans is generally much longer than the bridge itself. The form of construction suitable for the ramps may have a dominant influence on the final form of the bridge.

Application

Pedestrian bridges can be useful for linking buildings or popular destinations (e.g. shopping centers, large schools, recreational facilities, parking garages, light rail stations). They are also useful for linking areas separated by highways of freeways, where at-grade crossing are not permitted. Additionally, pedestrian bridges can be used for trail crossings. Ultimately, pedestrian bridges can be used in three situations, including: (1) crossing interstate highways, (2) crossing natural physical obstacles like rivers, or (3) crossing railroads. At some intersections, a pedestrian bridge might be a better investment than a road-level crossing. These intersections may call for designs that utilize a natural “desire line” where pedestrians will be inclined to use the bridge.

Our company

Our experienced team is focused on your steel bridge project's success, from start to finish. Our proven ability to identify and overcome design inconsistencies, potential problems with erection, and shipping obstacles results in the fabrication of structural steel that is right the first time, helping you avoid costly construction delays.

Proper project coordination and efficient delivery of the structural steel to your bridge project is a key factor in its ultimate success. This is what gives us the leading edge.

From material purchase and tracing, planning compilation, drawing detailing, production arrangement, quality inspection, to on-going painting, packing and delivering, we have separated department to strictly control process, quality and traceability, so that the perfect Bailey/Belay/Baley Bridge can be made.

Finally we would like to emphasize that not like other companies, nearly all machining parts and mechanical accessories are manufactured in our own shop as we have so many wonderful machines and workers inside. In this way, the quality, cost and delivery time can be ensured which eliminates other exterior factors’ influence.
