FIELD: construction.
SUBSTANCE: method of ice crust formation includes development of a dam across a river and arrangement of ice holes above the dam along the river flow. The dam is made in a narrow area of the river with erosion-resistant shores by means of stakes driving-in across the river channel. In winter an ice hole is arranged, and straw, ice pieces, stones wrapped into polyethylene film are laid under ice to create a dam. Arriving water floods shores and forms ice crust.
EFFECT: invention makes it possible to reduce material intensity and to simplify process of structure erection.
