FIELD: construction.SUBSTANCE: invention relates to construction and can be used when building embankments of second railway tracks, mainly on weak at thawing permanently frozen soils and moors. Road structure at double-track contains bank of first track and second track bank topped up to it, as well as anchors and planar reinforcing elements arranged at angle to slope of first path bank under main platform of second track bank. Along slope of first track on side of topped up second track there are at least two benches, at least two anchors are buried into body of first track bank in angle of each ledge along it at angle of 45-90° to vertical axis. Each flat reinforcing element is placed on projection of each ledge angle anchors to upper edge of anchor and is fixed with them, each anchor, which length is equal to 0.3-0.4 width of main platform of second track bank, is buried into body fill of first track of not less than 0.5 of its length.EFFECT: technical result consists in increasing of service life to standard due to preservation of integrity of earthwork structure at double-track owing to providing operating permissible parameters of structure during normal service life.3 cl, 1 dwg |
