Budapest Is Looking Forward To Its New Metro Line M4

摘要

The 13.5m-long formwork was placed on a support construction 9.5m long, thus creating a mobile unit. Pouring was undertaken with a pump and in 24 cycles, each with a maximum length of 12.5m. The pouring rate was o.7-o.8m per hour. Special attention had to be paid to the concrete consistency and the narrow conditions called for careful handling of the internal and external vibrators. The new Metro line is planned to be finished in 2009 and commence service in May 2010.
