PONTOON BELT BRIDGE Russian patent published in 2014 - IPC E01D15/14 

FIELD: construction.

SUBSTANCE: invention relates to transfer-bridge facilities, i.e. to pontoon bridges. A pontoon belt bridge with three traffic lines includes collapsible river and coastal links joined to each other in longitudinal and transverse direction by means of joint units, and the links comprise hingedly connected pontoons equipped with traffic areas built into decks. Height of pontoons of the middle traffic line is 1.4…2 times higher than the height of pontoons of the extreme traffic lines. Width of the traffic part of the middle traffic line is equal to 15.3…16 m, and width of the traffic part of each extreme traffic line is equal to 6.5…7 m.

EFFECT: using proposed technical solution will make it possible to increase load capacity and throughput capacity of a pontoon belt bridge approximately twice due to increase of its longitudinal strength and expansion of traffic parts of extreme traffic lines.
