FIELD: physics.
SUBSTANCE: method for forming safety barriers during establishment of special radioactive waste disposal facility includes supply of barrier material through a pipe by gravity and movement in a horizontal direction by a stream of compressed air passing through the air duct. Bags filled with a clay barrier material are placed above the feed hopper of a receiving chamber provided with metal blades and, after being ripped, are fed by gravity along the guide channel to a sieve. They are sifted, grinded and moved to the mixing chamber. They are aerated with compressed air at an operating pressure of about 1.5 kp/cm2 and moved along the transport pipeline in a horizontal direction into the corrugated pipe.
EFFECT: invention allows providing cavityless filling of hollows with barrier materials.
