METHOD FOR CREATION OF ICE-BOUND CROSSING Russian patent published in 1999 - IPC

FIELD: ice application technology. SUBSTANCE: this method can be used for building ice-bound crossing intended for transportation of cargo. Realization of this invention is aimed at enhancing reliability of ice-bound crossing. Obligatory requirement is presence of intensive water stream under ice cover. According to method, thickness of ice cover is increased. For this purpose through-slot is cut in ice cover and inserted though this slot is board which is oriented perpendicularly to direction of under-ice water stream. Board is installed at incline and it is provided with flange on its upper flange which is fastened on ice surface by way of freezing it into ice cover. Fastened to lower flange of board over its entire length is strip of impermeable fabric. EFFECT: higher efficiency. 1 dwg
