Railway apparatus foundations
A foundation 10 for railway apparatus 28, for example an electrification column or signal post, comprises a plurality of pre-formed blocks 12, 14, 16 in a substantially vertical stack. Each block 12, 14, 16 has an abutment surface that abuts an adjacent -formed block 12, 14, 16, and a bore extending though the block to an opening in the or each abutment surface. Corresponding bores of adjacent blocks are in registration, and a tensioning member 18, tensioned to apply a compressive force to the stack, extends through the bores of adjacent blocks and is fixed at each end relative to a corresponding end block 12, 16. Blocks 12, 14, 16 may typically each weigh between 1 tonnes and 10 tonnes, for example between 4 tonnes and 6 tonnes, and may comprise concrete with a steel wire reinforcement. Foundation 10 may be erected below the ground surface; alternatively, at least 30% of the foundation may be exposed above ground.
