Introduction of Bailey Type Trestle Bridge And Platform

The Bailey trestle bridge,also known as a temporary access bridge or a trestle bridge, is a structure built to provide access for construction activities. It is mainly used during the construction of large - scale infrastructure projects such as bridges, ports, and dams. For example, when building a long - span sea - crossing bridge, the trestle bridge allows construction vehicles and equipment to transport materials and workers to the construction site over water or difficult terrains.

Features of Bailey Type Trestle Bridge 

Transportability:

The modular components of the Bailey trestle bridge can be easily transported, often by truck or rail, to the construction site.

The lightweight and compact nature of the individual elements facilitate efficient transportation and handling.

Reusability:

The Bailey trestle bridge components are designed to be disassembled, transported, and reassembled at different locations.

This makes the Bailey bridge a cost-effective and efficient solution, as the same materials can be used repeatedly for various temporary bridge projects.

Applications of Bailey Type Trestle Bridge 

Bridge Construction Projects 

Trestle bridges play a vital role in transporting heavy construction materials such as steel girders, concrete segments, and pre - cast elements to the construction site. For example, during the construction of a suspension bridge, the trestle bridge provides a path for cranes to move the massive cable - spinning equipment and the components of the bridge deck to the center of the waterway.

Port and Harbor Construction

In port construction, a trestle bridge is often used to connect the land area with the dock under construction. It enables the transportation of heavy port equipment such as quay cranes and gantry cranes to the dock area. Additionally, it allows for the delivery of building materials like large - scale concrete caissons and steel piles used for the construction of the quay wall and the dock structure.

Dam and Hydraulic Structure Construction

For the construction of dams and other hydraulic structures that are often located in valleys or across rivers, a trestle bridge is necessary. It provides access for transporting earth - moving equipment to excavate the foundation of the dam and to transport the fill materials such as rocks and soil for the dam body.
