FILLED STRUCTURE UNDER EMBANKMENT Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: this structure relates to filled structures of bridge type used in road building industry. Structure has double-cantilever span construction with sides and intermediate supports. Specific feature is that double-cantilever span construction is made in the form of shell or fold which is provided with end diaphragms, intermediate diaphragms and supporting diaphragms. Shell or fold is used as platform for fill. Located in ridge of platform is reinforced concrete relieving slab. Shell or fold itself operates as baffling screen which reduces impact loads of wave origin produced by vehicle wheels. This leads to reduction of dynamic load brought to bear on ground of fill by one and half to two times. Aforesaid embodiment of filled structure possesses high degree of stability at lower weight of fill and less materials used in erection of structure. EFFECT: higher efficiency. 1 cl, 2 dwg
