Tunnel formwork system Formkret

Innovative System for Automated Formwork Filling Leading engineering group Kern Tunneltechnik and specialist concrete pumps manufacturer Putzmeister have formed a strategic partnership for the development of concrete delivery solutions in tunnels. The automated formwork filling system combines Kern’s state-of-the-art formwork solutions for tunnels with Putzmeister’s leading technical expertise in concrete pumps, to optimize the concrete-pouring process in underground construction sites while delivering significant time and cost savings. The Automated Formwork Filling System is regulated by a set of 2-way valves integrated in the formwork structure, and connected by a single delivery line that links the entire system in sequential rows. Key Features Automation means reduced workforce on site Faster overall tunnel construction and quicker hydrostatic filling process Reduced labor-related costs Compact structure allows simultaneous work Contains a stationary concrete pump, BSA 1408 E, and the Bespoke Formwork from Kern Technical Details General Information Max. Hydraulic Pressure 200 bar Delivery Line (DN + Pressure) 125/85 mm/bar Max. Ambient Temperature -15/50 degree
