INNOVATIVE CONCRETE SOLUTION TO EMBANKMENT STABILISATION

A major assessment of assets by rail operators in the UK identified the need for improved embankment stability to improve train reliability and to enable maintenance requirements to be predicted more accurately. Cementation Foundations Skanska developed the CemRailBeam system to reduce the costs of traditional embankment stabilisation programmes. In-situ concrete is used for vertical and raking piles under a bored precast capping beam that retains the track bed. The vertical piles stabilise the embankment by intersecting with slip surfaces. The raking piles act as anchors. The development of the system is outlined. Cementation also developed new techniques for constructing crest walls. These replaced scaffold platforms with engineered fill roadways and allowed concrete to be used in piles instead of grout. The CemRailBeam precast permanent shuttering system incorporates cast-in shear steel and can be installed by unskilled labour.
