Reconstruction of a railway junction in Prague – the New Connection – securing an east portal of new railway tunnels under Vítkov hill


Reconstruction of a railway junction in Prague – the New Connection – securing an east portal of new railway tunnels under Vítkov hill

Construction of the so called New Connection has become the most signifi cant part of an extensive reconstruction of the Pratur railway junction; the construction includes, among other things, two new 1350 m long tunnels under Vítkov hill ranking among the longest in the Czech Republic. East tunnel portals were built in a steep terrain slope; with respect to the position of both tunnel tubes only two cut walls were carried out here – the south and modele one, as well as two tube portal walls. The cut walls were secured by a scheme of micropiles up to 30 m long anchored with permanent strand and bar anchors and reinforced with shotcrete. Apart from securing these vertical cuts the works realised inside the north and south tunnel portals included carrying out micropile umbrellas for the subsequent tunnel driving.
