METHOD TO ELIMINATE ICE CLOGGING THAT CLOSES RIVER FROM ONE COAST TO OPPOSITE ONE AND RAISING WATER LEVEL IN RIVER Russian patent published in 2012 - IPC E02B15/02 

FIELD: construction.

SUBSTANCE: method includes filling an explosive substance under ice clogging on the river bottom in the specified area and simultaneous explosion of the entire explosive carried out at the specified level of water in front of the clogging and in the volume sufficient to develop disturbance that changes into an elastic wave in water that impacts the clogging and then puts the clogging first into oscillating motion and then into the motion along the river. At the start of the work a section of the coast is identified, which at least near the head part of the clogging has a coastal depth that is deeper than the coastal depth near the head part at the opposite coast. Filling of the explosive substance is carried out at the specified depth along the specified section of the coastal line of this identified section, afterwards the entire explosive substance is simultaneously exploded. Simultaneously with putting the clogging into oscillating motion, the head part of the clogging is exposed to firing practice with live shells.

EFFECT: using invention will make it possible to increase efficiency of explosion operation during elimination of the clogging.
