STREAMLINED SUPPORT OF BRIDGE PASSAGE PLACED AT ANGLE WITH WATER COURSE Russian patent published in 2003 - IPC

FIELD: bridge construction, design and reconstruction of bridge passages. SUBSTANCE: streamlined support of bridge passage placed at angle with water course comprises reinforced concrete shells which internal spaces id filled with concrete. Novelty of approach consists in that streamlined support includes lower part which axis is parallel to axis of water course and upper part made of rows of reinforced concrete shells twisted by height, axes of shells placed above are displaced relative to axes of shells placed beneath through certain angle depending on angle of crossing of water course by bridge passage and height of upper part. Horizontal axis of upper part of support is turned with reference to its initial position from axis of water course to perpendicular position to bridge passage. EFFECT: reduced usage of materials due to shortened length of bridge passage and to employment of typical beams rectangular in plan. 7 dwg
