    Detailed Product Description

    Description:

     

    D-bridge is the patent of Great Wall;It was invited from Germany and has advantage in the long-span and big loading comparing to bailey bridge. Thus, it can save cost of piers.

    Its panel chord is bigger than bailey bridge panel but the panel structure is simpler. All the components are bolted so the bridge can be used as a permanent bridge because of its small deflection..The components are interchangeable and repetitively used.This kind of bridge has various structure changes to satisfy different loading capacity.
     


    The surface protection can be paint or hot-dip galvanized.

     

    Specifications:

     

    Specifications:  
    Single lane Standard roadway: 4.2m Single span: 35m-81m
    Double lane Standard roadway:7.35m Single span: 35m-72m
    Load: design according to different requirements  
    Deck: steel deck / concrete deck

     


    Competitive Advantage:

     

    • Heavy loading capacity
    • Used as permanent bridge
    • Great stability
    • Simple in structure
    • Long service life
    • Rapid in erection

     

    Introduction

    GW D bridge is a standard bridge equipment, adopted extensively and the most popular in the world


    Advantage

    Possessing the features of simple structure,
    convenient transport, speedy erection
    easy disassembling,
    heavy loading capacity,
    great stability and long fatigue life
    being capable of an alternative span, loading capacity


    Features

    1. High strength and big stiffness , relative to the concrete bridge can be reduced trabecular high and self-respect
    2. Due to the steel isotropic, quality of a material is uniform and modulus of elasticity, that make steel bridge in the working condition and calculation compared with the assumption
    3. Steel bridge generally prefabricated factory, site splicing, the construction period is short, processing convenient and not affected by seasonal effect.
    4. Steel bridge is suitable for industrialized manufacture and very convenient to transport.
    5. Steel bridge is easy to repair and replace,long lifetime,material can be recycled.


    Application

    Beam bridge,arch bridge,rigid frame bridge,cable-stayed bridge,suspension bridge. passenger foot-bridge


    Mixture form to erect all kinds of

    Temporary Bridges, Emergency Bridges and Fixed Bridges.
    Using the bridge equipment, the suspension bridges of varied span can be erected.
    The bridge has the advantages of few components, light weight and low cost.
    Bailey Bridge requires no special tools or heavy equipment for construction, the bridge elements
    are small enough to be carried in , and the bridge is strong enough to carry . It is considered a great example of military engineering.


    The compact 200 panel bridge: The compact 200 panel bridge is similar to the compact 100 panel
    bridge from their appearance. The difference is its increased panel height to 2.134m. It employed the method of alternating joints between Reinforcement Chords and the joints between panels. This method can decrease inelastic deformation caused by the oversized pinholes.
    Pre-arch method is used to additionally cut down mid-span and vertical deflection to a larger degree.
    Bolt-connected components use the orienting sleeve- fixing method to increase accuracy of connections. Shear is created in orienting sleeves and tension is developed in bolts, which increase the usage life of the bolts and ensure the safety of panel bridges. Wind resistant brace is made to be composite type and is connected to transom/girders to improve overall stability of panel bridges.
