METHOD FOR DESTRUCTION OF ICE COVER Russian patent published in 2015 - IPC E02B15/02 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering, namely to the protection of industrial facilities, lines of transportation, communication, various constructions against the harmful effects of water, and can be used to break the ice cover on rivers and water reservoirs. Method involves drilling of holes in the ice cover and laying of supply pipelines in them with subsequent destruction of the ice cover. Destruction of the ice cover is carried out via hydraulic fracturing by unregelating liquid, supplied under pressure into the previously pressure-sealed areas of these holes. Security for people during destruction of the ice cover is provided due to the possibility of its destruction from a safe distance, as well as safety improving for the engineering constructions and environmental safety.

EFFECT: increased efficiency of the method due to the possibility of destruction of the ice cover into pieces of specified sizes in case of stratified break.
