BRIDGES

Bridges are a core area of activity of BBR Polska. Since 1994 our technical solutions have found application in hundreds of engineering structures in Poland. Being constantly developed they fulfill the newest technical requirements, and a broad variety of solutions allows us to adjust our offer to the specific expectations of our clients.


PRESTRESSING SYSTEMS


BBR prestressing systems are applied in the construction of new structures as well as in strenghtening existing ones. They include prestressing tendons with bond, external tendons and external unbonded tendons. The range of available solutions is completed by prestressing bar systems.


STAY CABLED SYSTEMS


The suspension of bridge structures requires a unique and individual approach every time, as well as a system suited to our clients' needs. Our team of experienced engineers will support You in the choice of appropriate stay cables, arch bridge hangers or cables for a suspension bridge.


CONSTRUCTION METHODS


The execution of a bridge structure without the option of direct support, or when it is not economically viable require the usage of one of the advanced construction technologies. For years BBR Polska has been offering solutions in the scope of cantilevering methods, such as cantilevering cast-in-situ construction , as well as incremental launching of steel, compotite and concrete bridge superstructures.


EQUIPMENT FOR BRIGDE STRUCTURES


MAGEBA bridge modulal expansion joints are designed under the principle of elastic connections. Reciprocally moving steel components are connected with a deformable element. This allows for the independent functioning for each of the modules, whilst also damping the impact carried over to the construct and reducing the noise of passage.


REINFORCED EARTH STRUCTURES


The PANEL WALL reinforced soil system can be used in the construction of a bridge abutment, or as an independent resistance construct. The large size of the facing elements allows for a fast construction speed. The columns of pannels do not overlap, thanks to which the retaining wall gains a high tolerance to unevenly distributed settlements.


REPAIRS AND STRENGHTENING


The technologies of BBR Polska also find use in the strenghtening of already existing constructs. External PT tendons transfer loads pointwise in the locations of anchorages and on the deviators. New structural elements can be joined together with the pre-existing ones with the use of prestressing bars. BBR Polska offers a full suite of the aforementioned solutions.
