FIELD: building, particularly to construct temporary roads across lakes and other water obstacles.

SUBSTANCE: ice bridge includes cooling plant, pipelines connected to cooling plant. Pipelines are submersed in water and suspended by wire ropes. Cooling plant has reducers for pressure reduction, 10 MPa gaseous nitrogen cylinders and liquid nitrogen cylinders adapted to fill pipelines with liquid and gaseous nitrogen mixture. The pipelines include several coiled sections or formed as straight and finned pipes. The pipelines are arranged in several rows and extend in vertical or horizontal directions. The pipelines are submersed for 0.1-5 m depth and are connected by wire ropes to balloons floating at water surface or to finned pipes driven in ground of river bottom and connected one to another by diaphragms. The cooling plant provides water freezing within 3-5 km range and obtains ice having thickness of 3 m or more.

EFFECT: increased water freezing rate.
