Modular Steel Bridge

Modular Steel Bridge

Description:                     

GW D Modular bridge are new kinds of assembly steel bridges, comprising longitudinal trusses that are formed of steel beam chords and pre-fabricated modular steel panel webs, connected end to end with transverse cross girders spanning between them that support a two lane or a single lane, steel deck roadway or concrete roadway.

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

Introduction

Bailey 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. It can be configured to various lengths and widths to accommodate different span requirements. They can be assembled in single or multiple lanes, and their modular design allows for flexibility in adapting to different terrain conditions.

3. GW D Modular bridge generally prefabricated in factory, site assembled by pins and bolts; the construction period is short, processing convenient and not affected by seasonal effect.

4. GW D Modular bridge is suitable for industrialized manufacture and very convenient to transport.

5. GW D Modular 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.
