FIELD: protective equipment.
SUBSTANCE: invention relates to techniques for treatment of toxic and radioactive substances and can be used in development of field deposits with filling of mined space. During erection of envelop from buses the internal clearance between them and containers is filled with construction foam based on liquid pre-polymer with propellant forming rigid polyurethane. Foam supply height is accepted equal to half the height of protective envelope when the whole volume of foam is supplied simultaneously.
EFFECT: technical result consists in reduction of labour intensity when creating envelops and reduced risk of corrosion of containers.
