2014 Tunnelling Conference Innovation Award

New Method for the Production of Earth Pulp for Tunnel Boring Applications

At this year’s Austrian Tunnelling Conference held in Salzburg in October, the Austrian National Committee of the International Tunnelling Association (ITA) presented the “Tunnelling Conference Innovation Award” to MC-Bauchemie Müller GmbH & Co. KG and Porr Bau GmbH. They impressed an independent jury of experts with an innovative method for improving the production of earth pulp (muck) for Earth Pressure Balance (EPB) shields. This new process extends the working range of the EPB technique and significantly reduces the volume of conditioning agents used, leading to positive effects on the...
