摘要
FIELD: construction.;SUBSTANCE: invention relates to construction, namely to support walls, retaining soil pressure, used in construction sites and construction of railroads and roads. Composite levelling unit, arranged above upper part of underlying concrete soil retaining wall and below road driveway, comprises front part with front face, rear face, top face and bottom face. Front face is parallel to rear face, upper edge is parallel to longitudinal slope of road driveway, lower edge is perpendicular to front face, top face is not parallel to lower face. Horizontal thrust rib projects from rear face of front part and comprises triangular part, extending to the left and right relative to upper plane of horizontal rib, as well as square holes in lower part of prefabricated levelling unit. Levelling element extends outward at least at part of horizontal support rib. Concrete soil retaining wall has no slope and lower face of front part is parallel to underlying retaining wall, retaining soil pressure. Composite levelling unit is located below assembly unit of barrier enclosure and above concrete retaining soil wall, road driveway with longitudinal slope is located below one part of assembled unit of barrier enclosure but above other part of barrier enclosure.;EFFECT: technical result consists in improvement of reliability of structure, providing barrier repeating varying vertical lengthwise profile of roadway.;16 cl, 16 dwg
