Wall structures acting as noise barriers for railways and the use of wall structures as noise or traffic barriers

摘要

The object of the invention is a wall structure working as a noise barrier for railways, which comprises at least a plurality of wall elements placed consecutively end-to-end with each other, which wall elements are hinged by means of hinge pieces at their bottom edges for toppling downwards from their vertical position. The wall elements are disposed inside the width reach of the wagons or cargo space of a train and for toppling by means of the hinge pieces to below a wagon or a load that is lower than normal and/or is overwide. The wall structure is suited for use e.g. as a noise barrier or passage barrier for a railway.
