йолностью ликвидируетс  отслоение защигного бегонного сло  от сердечника, что обеспечивает долговечность напорных труб. Формула изобретени  Способ нанесен защитного сло  на металлический сердечник напорной трубы путем смачивани  его наружной поверхности кле щим составом с последующим нанесением торкретированием бетонной смеси, отличающийс  тем/ что, с целью ликвидации отслоени  защитного сло  от сердечника, перед торкретированием на наружную поверхность; .сердечника нанос т 7 слой сухого песка с размером частиц 1 - 1О мм, а в качестве кле шего состава используют эпоксидную смолу. Источники информации, прин тые во внимание при экспертизе: 1,Авторское сввдетельство СССЬ NO 531743, кл. В 28 Ь 21/44, 1975. Exfoliation of the protective begon layer from the core is completely eliminated, which ensures durability of pressure pipes. Claims The method is applied with a protective layer on the metal core of the standpipe by wetting its outer surface with an adhesive and then applying a concrete mix by gunning, characterized in that, in order to eliminate peeling of the protective layer from the core, before gunning it to the outer surface; The core is coated with 7 layers of dry sand with a particle size of 1-100 mm, and epoxy resin is used as the adhesive composition.
