STRUCTURAL ARRANGEMENT AND PROCEDURE FOR THE STABILISATION OF LINEAR EARTHWORKS

摘要

The subject of the invention relates to a structural arrangement for the stabilisation of linear earthworks, i.e. mainly railway line superstructures, for the prevention of movements of the superstructure due to the effect of forces transverse to the direction of the trace line, whilst intermittently maintaining traffic. The invention's distinctive feature is that the load-bearing support structure is made up of a support beam (3) stabilising the ballast bed (21) and running alongside the trace line on the side of the sleepers (22) where movements tend to occur, and a supporting wall (4) located at the other side of the support beam (3) opposite the sleepers (22), extending from the superstructure (2) down towards the subsoil, and a protective blanket (5) covering the support beam (3) and the supporting wall (4), simultaneously embracing the ends (22a) of the sleepers (22) facing towards the support beam (3). The invention also encompasses the procedure for creating the structural arrangement; this procedure involves building the support beam (3) stabilising the sleepers (22), which are part of the railway superstructure, and the ballast bed (21) under them, and running alongside the trace line on the side of the sleepers (22) where movements tend to occur, and constructing, when indicated, a supporting wall (4) in the earth lying up against the other side of the support beam (3) opposite the sleepers (22), covering the support beam (3) and the supporting wall (4) with a covering blanket (5), and constructing a drain (7) underneath the supporting wall (4) if necessary.
