摘要
FIELD: bridge building. SUBSTANCE: first temporary carried out technological support for bridge building machine is constructed from bank before use of the bridge building machine, that is done for each successive stationary intermediate support. In so doing sectional double-track mechanized bridge of gantry type is used as carried out technological support that rests, for example, on ground. The mechanized bridge is laid down and removed using bridge laying device for mechanized bridge of higher carrying capacity. Mechanized bridge of increased carrying capacity is laid using said bridge laying device after construction of stationary intermediate support and removal of technological support with bridge building machine. The mechanized bridge is used as the first span laid from bank to the line of passage at the first stationary support, as well as successive initial building platform to lay down carried out technological support for erecting successive stationary intermediate support with successive laying down the next mechanized bridge of higher carrying capacity. EFFECT: accelerated construction of bridges. 2 cl, 4 dwg
