FIELD: power industry.
SUBSTANCE: on external surface of the enclosure the reinforcement grid is secured, and shotcrete layer is applied under compressed air, the layer covers the grid and includes portland cement, fillers, chemical and mineral additives, and water. At that grid with cell at least 110×110 mm is used, it is made out of nanomodified basalt-plastic reinforcement rods with sand external coating, the grid is installed with clearance 8 mm maximum from the shotcreted surface, and shotcrete is applied with definite ratio of components. Under particular case of specified method of shotcreting of the enclosure external surfaces to reduce its weight and dimensions the maximum layer of the shotcrete with thickness 25 mm is applied.
EFFECT: increased storage life of the enclosure.
