The elements DZR 5, 6, 7, 8 serve for forming of mounted frame underpasses for station luggage tunnels, for pedestrian underpasses and for buildings for other purposes, i.e. simple ones only. They are adapted for jointing by monolith forming. In contrast to the element DZR 7 they have another structural length.
They are designed for continuous load given by the gravel bed thickness from 0.55 to 1.0 m and moving load given by the heavy load train ČSD T, the standard load of which is given by a set of axle forces 4 x 312.5 kN and by the uniform load 100 kNm-1.
