SPORTING AND RECREATION COMPLEX " VOROBYEVY GORI "IN THE FORM OF BRIDGE PASSAGE OVER RIVER Russian patent published in 2003 - IPC

FIELD: civil engineering. SUBSTANCE: invention refers to design of bridge passages of various assignment built proceeding from pubic demand in close proximity to used, preferably reconstructed, motor-road and metro bridges and utilized upon their construction as sporting and recreation complexes, for instance ski complex. Sporting and recreation complex in the form of bridge passage over river near reconstructed two-level metro bridge includes superstructure linking upper and lower stations mounted on supports predominantly of broken section ( rod-type, lattice-type or X-shaped ). Longitudinal axis of section of bridge passage located above river is arranged in plan in parallel or at acute angle of 15 degrees with longitudinal axis of metro bridge. Axis of section positioned underneath is oriented in plan at acute angle with longitudinal axis of metro bridge and longitudinal axes of sections located above mentioned section form bend in plan, preferably U-shaped, with middle part oriented away from longitudinal axis of metro bridge. Uppermost section of superstructure has horizontal platform passing to section of superstructure positioned above river bank with maximal slope of sections following it amounting to 22-26%, section located next to it located above river bank and joined to it is shorter in length and has slope of 16-20%. Horizontal section located above support, passing over river and having longest length has slope from 14 to 16%. Section positioned after it has slope from 16 to 19% and goes into horizontal platform or platform with opposite direction of slope. Supports of section of superstructure of bridge passage are arranged uniaxially with line of arrangement of supports of river course superstructure of metro bridge or with displacement with reference to them towards sections of superstructure placed beneath. Ski path with inclinations corresponding to above-mentioned slopes of sections of bridge passage laid along sections of bridge passage. Line of suspended seat elevators and/or rope tows is laid at least on one side of ski path. EFFECT: construction of lightened bridge passage over river near used metro bridge with due account of dynamic loads created by it as well as complicated geological conditions of territory and its relief which secures maximal utilization of existing allotted land with considerable difference in heights. 7 cl, 3 dwg
