FILLED STRUCTURE UNDER EMBANKMENT Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: filled structure relates to artificial structures of motor roads and can be used in building of bridge-type units with plate-type span elements of membrane configuration or double-cantilever systems. Filled structure has intermediate pile supports, supporting enclosed contour, combination double-cantilever span unit. Enclosed supporting contour is made with elevated main side girders which are conjugated by lateral diaphragms in ends of cantilevers, planes of intermediate supports and in intervals between them. Main side girders from bottom side contain elongated embedded articles, and connected to them are ends of cylindrical membranes. In this way, span unit is made in the form of cylindrical membrane which is secured in lower part of longitudinal inclined sides which constitute part of enclosed supporting contour provided with lateral struts in ends of cantilevers in plane of setting intermediate supports and in their intervals ensuring stability in positioning of contour and better distribution of permanent load produced by fill and periodic moving load that is by traffic. EFFECT: higher efficiency. 1 cl, 2 dwg
