Cast and milled – monolithic concrete manholebases from Denmark

Following on from the commissioning of the first monolithic concrete manhole base production line with the Primuss System from Prinzing in 2009 (see CPI 5/2009), there are now already ten concrete production facilities using this system not even two years later in six European countries. Just recently, the family-run business of Gammelrand Beton A/S in Denmark took the step of investing in the Primuss System. After its run-in period, final testing was carried out by Prinzing technicians at the end of May. In the nine other concrete production facilities with a Primuss production line, manhole channels and connections are milled with a milling robot into partially hardened concrete blanks manufactured only a few hours beforehand from zero slump concrete on a Prinzing Atlas system. Gammelrand, however, decided on a solution with concrete blanks cast from self-compacting concrete. As the company only manufactures concrete manhole bases with a fixed diameter but with variable heights, the need for moulds is rather limited. All moulds in stock can thus be employed for any order.
