Underground Station, Móricz Zsigmond Platz, Budapest, Hungary
Load-bearing and flexible up to heights of 18 m
7.3 km long is the first section of the M4, the new fourth line of the Budapester Metro. It passes through under the Danube and features a fully automatic, driverless operation - at 90-second intervals, up to speeds of 80 km/h. The Metro station below the Móricz Zsigmond Platz, with numerous tram and bus connections, is considered to be a very important traffic junction. The formwork and scaffolding solution developed by PERI´s Hungarian engineers took into consideration the static and architectural requirements. Then, high loads at great heights had to be transferred as well as concrete components in architectural concrete quality with a fixed joint and tie arrangement were to be constructed.
The northern and southern completions of the Metro station are comprised of inclined 48° and 59° reinforced concrete slabs respectively which were constructed in 3 cycles of up to heights of 18.70 m. Safe load distribution was carried out through GT 24 formwork girders and SRU steel walers, a raised formwork construction comprised of SRU steel walers and SLS heavy duty spindles ensured the spatial adjustment. The shoring solution installed under this was based on the MULTIPROP system, with MULTIPROP aluminum slab props connected by MRK frames.
With the help of the rentable, modular PERI construction kit, a pre-cast crossbeam could not only be adapted but also integrated into the load-bearing system as a bracing element.

“The co-operation with PERI ran smoothly both in planning as well as the execution phase. The flexibility and load-bearing capacity of the MULTIPROP system used for supporting the diagonally-positioned components was a great advantage.”
