What should you pay attention to when leasing a Bailey Bridge?

Bretagne Bridges are more representative and widely used. Their application has evolved in prefabricated steel bridges and was standardized for mass production in 1965. For instance, during the 12 earthquakes in 2008, a significant number of Bretagne Bridges were employed for rescue and relief efforts. These bridges play a crucial role in the early transportation of earthquake relief supplies, the later transportation of the injured, and the evacuation of the public. Before using the Bretagne plates, parameters such as truss selection and spacing should be designed based on the load, with a focus on stability, especially for the Bretagne columns. They have developed in China and are widely used in national defense readiness, traffic engineering, and municipal water conservancy projects.

Due to their ease of installation and mobility, these bridges are primarily used for constructing simple crossings over rivers and cliffs during wartime. Currently, they are mainly employed in construction projects for crane gantries, construction passages, and engineering bridges. The design and calculations encompass aspects such as formwork support, foundation support, dewatering, construction bridges, structural advancement, caissoning, soft foundation treatment, prestressed tension, heavy component lifting, concrete pouring, and equipment, among others. Standards and specifications should be adhered to in order to ensure structural stability and strength.
