FIELD: hydraulic oil production structures, particularly artificial islands mounted on piles or like supports, platforms on raisable legs, namely support parts of connection bridges arranged between oil production platform and inhabited module platform. ^ SUBSTANCE: connection bridge comprises piers and load-bearing span structure. Each pier comprises support panel, fixedly connected with corresponding platform. Linear displacement limiters are fastened to support panel. The limiters are made as vertical paired parallel panels arranged so that load-bearing span structure piers are installed in-between on support panel. Each pier is made as balance beam fixedly connected with span structure girder by the first end and rested upon support panel by the second end thereof. The second end is made as abutment having oval cross-section. Thrust disc, which provides cooperation with linear displacement limiter with taking into consideration predetermined gap, is arranged on balancing beam body. Longitudinal abutment axis is transversal to load-bearing span structure axis. ^ EFFECT: provision of pier unification along with simplified structure and provision of bridge operation in marine circumstances. ^ 3 cl, 8 dwg |
