METHOD FOR DOCKING OF RIVER PARTS OF FLOATING BRIDGES MLZH-VF-VT AND NZHM-56

摘要

FIELD: construction.;SUBSTANCE: invention can be used when guiding combined floating railroad bridges from different types of property of MLZH-VF-VT and NZHM-56 pontoon parks. Method for docking of river sections of floating bridges MLZH-VF-VT and NZHM-56, including reinforcement (widening) of butt section of MLZH-VF-VT over five river links by additional P-pontoons with installation of inserts of longitudinal joint device of MT9 grade and reinforcement of butt section of NZHM-56 with double pontoons under sections of span structures, as well as connection of river parts of bridges to single floating system through special connecting beam on bolts to section of span structure of NZHM-56 through flange corners and L-shaped straps and by means of rods of longitudinal attachment of piers MLZH-VF-VT and NZHM-56 to each other with providing connection and transfer from high level on span structure of NZHM-56 to lower level of deck of MLZH-VF-VT railway passage by installation on rails of pontoons of PR blocks of ramp with preliminary laying on rails of strip (laying) from same rough polymeric material united with the connecting bolt between a beam and by means of flanged units, as well as with the piers MLZH-VF-VT through special ramp fastening beams, which are shortened pontoons of BPR, BP, BK brands and bridge-tapes of the appropriate brands (PR, P, K) built between standard pontoons, as well as arrangement of through passage of wheeled and crawler vehicles from separate road passage NZHM-56 to deck of pontoons P and PR of MLZH-VF-VT installation between bridges of different design of shortened section of road passage and installation on deck of pontoons of brand P ramp for entry (exit) of cars, wheeled and crawler vehicles at level of road passage NZHM-56, as well as creation of comfortable operating conditions for operating personnel by metal ladders on sides of ramp for lifting from level of deck MLZH-VF-VT to level of lower parts of top of connecting beam (sidewalks on sides of span structure of NZHM-56) and device of inner-roller sidewalk flooring on ramp.;EFFECT: disclosed is a method of docking of river parts of floating bridges MLZH-VF-VT and NZHM-56.;1 cl, 9 dwg
