FIELD: building industry, particularly for performing waterproofing during structure erection.
SUBSTANCE: device for waterproofing gap between hollow cylindrical members having different diameters and arranged at least partly one inside another has shell of polymeric material, for instance of rubber reinforced by elastic fabric. Shell has closed annular shape. Shell is formed with end orifices of different inner diameters. Inner surfaces of shell orifices contact with corresponding hollow cylindrical members arranged at least partly one into another and with annular bands. Width of each annular band is not less than triple thickness of shell in areas of bands location. Relation between inner diameters of orifices bounded by bands is from 1.1 to 3.2.
EFFECT: increased operational reliability under interruption of alignment between cylindrical members and under change of relative cylindrical member lengths as a result of temperature gradient from -40oC to +50oC in different climatic zones or under axial displacement of cylindrical members during mounting or exploitation thereof.
