AUTOMOBILE-RAILWAY CROSSING THROUGH THE NEVELSKY STRAIT Russian patent published in 2019 - IPC E01D15/00 E01D12/00 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to construction of pontoon-and-barge bridges. Road-railway crossing consists of two standard overpasses and one extending barge bridge, formed of two 130-meter self-propelled barges of ice-breaker class, which dock in locking unit and form temporary 200-meter automobile-railway crossing. After the barges disconnection, they enter the docks lying opposite each other on the same straight line at distance of 200 meters, which are covered with multi-section main platforms, freely put on the pile guides, uniformly installed (in soil) along lateral sides of main platforms raised (lowered) by means of ropes, blocks and electric motors fixed on guiding piles. Sections of the main platforms are equipped with lifting and retractable railway and motor-car trailers. After barges exit from docks, ladders are lowered accordingly to lifted and (lowered) ramps hinged on barge deck. Two railway tracks are laid on barges and 8 auto lanes are arranged, which are also equipped with two main platforms and two additional multi-sectional structures and technologies of platform functioning adjacent to their rear ends, which provides for smooth descent (lifting) at sea level change in sea level on overpasses adjoining from platforms to platforms. Overhead lines are also equipped with two railway tracks and 6 auto lanes. In front of the docks there are lifting gates lifted and lowered before the storm along the guide piles by means of cables, blocks and electric motors fixed on the guide piles, and protective dikes with beacons are installed around the docks.

EFFECT: proposed is automobile-railway crossing through Nevelsky strait.
