M4 metro line - Rákóczi tér

Hungary

The underground railway station at Rákóczi tér is part of the new M4 metro line in Budapest. The platform zone of the station consists of three tunnel tubes. The walls were formed and poured in advance, with the aid of Doka supporting construction frames. Subsequently, the tunnel roof was cast using a combination of Staxo 100 shoring towers and Large-area formwork Top 50.
