Flexible waterproof casing

Abstract

The invention discloses a flexible waterproof sleeve which comprises a flange sleeve, a steel pipe, a flange gland and water stop rings. The flange sleeve horizontally penetrates an oblique concrete base body, the inclining direction of a flange at the inner opening port of the flange sleeve is consistent to an inclination angle of the concrete base body, the flange tightly adheres to an oblique plane of the inner side of the concrete base body, and a non-interfered distance is reserved between the flange at the outer opening end of the flange sleeve and an oblique plane of the outer side of the concrete base body. The steel pipe and the flange sleeve are coaxially arranged, and the flange gland press a rubber seal ring on the flange at the outer opening end of the flange sleeve between the flange sleeve and the steel pipe through a screw and a nut. A flexible joint filling material is filled between the flange sleeve at the inner opening end and the steel pipe, and a sealant is caulked into joints to achieve sealing. The water stop rings are evenly arranged on the flange sleeve at intervals. The flexible waterproof sleeve is especially suitable for installation of vibrating flexible waterproof sleeves with funnel-type side walls, a special usage mode of the flexible waterproof sleeve is changed into a common usage mode, the operability is good, and the flexible waterproof sleeve has general popularization significance.

Description

(1) Technical field: [0001] The invention relates to the production and installation of components in the engineering construction industry, in particular to a flexible waterproof casing. (two) background technology: [0002] With the continuous development of production and installation technology in the engineering construction industry, more and more technological effects need corresponding measures to achieve, and the atlas of the existing conventional design manual can no longer meet the needs of new technology development. [0003] For example, a flexible waterproof casing used for concrete containers that need to pass through pipes is currently designed with reference to the architectural standard atlas "Waterproof Sleeve 02S404". Construction, that is, the concrete matrix surface is perpendicular to the casing hole and the matrix is ​​of equal thickness. [0004] However, when the concrete base is inclined and the flexible waterproof casing needs to pass through hor...

AI Technical Summary

Problems solved by technology

[0004] However, when the concrete base is inclined and the flexible waterproof casing needs to pass through horizontally, the Atlas "Waterproof Sleeve 02S404" has no relevant content and cannot be realized by the above method. The reason is: it is made according to the principle of the Atlas, and the flange casing When the flange gland is tightened with studs and nuts, it is impossible to ensure that the flange gland enters horizontally. During the tightening process, the flange gland moves up or down, and the sealing performance of the rubber sealing ring cannot be guaranteed, which will cause the flange The steel pipe in the casing may collide with the flange gland and cannot be installed

[0005] There is still no good way to deal with the above problems
