Tunnel Construction with SBM Concrete Mixing Plants
The expansion of international traffic routes through the Alps would be inconceivable without tunnels. The realization of this costly infrastructure projects required first class concrete quality at economic conditions. The mobile concrete mixing plants from SBM Mineral Processing have proven themselves as a successful competitive factor. Just recently, the Austrian company delivered the 12th EUROMIX® concrete mixing plant to Europe’s largest mobile concrete producer. Thanks to shorter paths and fewer truck journeys, concrete production on the jobsite with the EUROMIX® concrete mixing plant reduces the CO2 emissions by around 25%. The cost savings are also significant thanks to a quick set-up time, great flexibility, high reliability, and longevity. A wheeled EUROMIX® is ready for operation within a days work, as no fixed foundation construction is necessary. The twin-shaft mixer of the EUROMIX® 4000 achieves an output of up to 170 m3/h. In addition to concrete mixing plants, SBM is the only company in the sector which also offers well-conceived total concepts for tunnel construction sites. Total concepts means that also for the material management first class solutions have been developed for the processing and conveying systems. In this way, SBM solves one of the biggest problems in tunnel building – the processing of excavated material, which after preparation can be reused as high quality aggregates for concrete production. SBM has developed a system which encompasses the whole production chain. It ranges from crushing, screening and conveying to washing, dewatering and storage right through to mixing of high quality concrete and its delivery.
