Concrete Casting

摘要

Concrete can be supplied to tunnel projects from commercial ready-mix concrete suppliers to specification. Alternatively an on-site or nearby batching plant can be justified by the economics of scale, the remoteness of the site or special mix considerations. CIFA offers a wide range of equipment applicable to concreting in tunnels including formwork, transport products, mobile mixers, pumps and batching plants. Depending on the design, these plants are made to produce output according to changing requirements and improve overall efficiency, especially in supply.rnThe main practical choices for getting concrete to its point of use in tunnels are greatly affected by the section of the tunnel and where it is practical to locate the batching plant. Depending on the logistics of the tunnel, drop-chutes, hopper or mixer trucks on rails or tyred vehicles, belt conveyors, and long distance pumping can all play a part.
