BBRAIL

The trenchless rehabilitation of sewers and culverts within the vicinity of railways places particular demands on the materials, dimensioning and execution. In addition to the usual stresses and pressure on underground pipes, particular attention must be paid to the dynamic and recurring traffic loads resulting from railway operations.

With the BB RAIL, Brandenburger Liner has developed a GRP pipe liner specifically for the rehabilitation of gravity sewers and culverts beneath railway lines. The product-specific approval by Deutsche Bahn AG confirms the system’s suitability for this demanding area of application.

• Specially developed for the rehabilitation of gravity sewers and passages where the burdens from rail traffic take effect.

• Enables fast rehabilitation of critical sections of the railway infrastructure.

• Round and ovoid profiles from DN 150 to DN 1000.

• Installation depths  ≥ 1,10 m bis 5,50 m. (please refer to standardised statics technical data sheet BB RAIL).

• Proven fatigue resistance with cyclic load (59.4 N/mm² at 10⁷ load cycles). 

• 3-10 % Expansion rate.

• DIBt approved within the scope of the BB^2.5.

• High mechanical rigidity, which enables the use of lower wall thicknesses as opposed to traditional CIPP liners and reduces the weight of the GRP liner.

• Excellent static features.
