Geotechnical
Building a robust temporary wall out of Lego precast concrete blocks could be done in under a day, with the blocks transported on the back of the maintenance trains transporting the machinery and equipment. Creating a much more formidable physical barrier than a basic line of tape, such a solution is already protecting a live railway line at the Drax coal-fired power station in Selby, Yorkshire, where Elite Precast Concrete was asked to build a ‘crash wall’
on a sweeping turn at the site entrance to ensure lorries delivering coal couldn’t skid onto the adjacent tracks in icy conditions.
A replacement for steel formwork Another area where precast concrete has the potential to be utilised within the rail industry is as a replacement for the steel formwork which is used when casting bridge supports and foundations. Interlocking blocks can be used as a permanent formwork, with the foundation
reinforcing being drilled and fixed into the blocks creating, a monolithic structure. This offers huge savings in plant, equipment and labour compared to having to remove conventional formwork once the foundations have cured. With examples such as these, and
many more exciting ideas to explore in the months to come, it’s clear the precast concrete industry and the rail sector are on the right track towards devising solutions and systems that not only enhance overall safety, but are also quick and cost-effective to implement.
