Brückenlagern

Brückenlagern is a term used in German-speaking countries to describe the practice of placing temporary supports or temporary bearings under a bridge during construction or repair. These supports are designed to hold the bridge structure in place while permanent elements are installed or while sections of the bridge are being worked on. Brückenlagern can involve a variety of materials and methods, depending on the size and type of bridge, as well as the specific work being performed.

The primary purpose of Brückenlagern is to ensure the stability and safety of the bridge during the construction or maintenance phases. It prevents undue stress on partially completed or weakened sections and allows for precise positioning of new components. This can include supporting the weight of bridge decks, girders, or other structural elements as they are lifted into place or as temporary loads are applied.

Commonly used materials for Brückenlagern include steel beams, hydraulic jacks, and specialized temporary bridge bearings. The design and implementation of Brückenlagern require careful engineering calculations to account for anticipated loads, environmental conditions, and the duration of the temporary support. Once the permanent structure is completed or the repairs are finished, the temporary supports are carefully removed. This process is crucial for the overall success and integrity of bridge construction and rehabilitation projects.
