Self-waterproof casing pipe convenient to install

Abstract

The invention relates to a self-waterproof casing pipe convenient to install. The self-waterproof pipe convenient to install is mainly used for waterproof use of pipelines penetrating water pool walls in the field of building engineering and can also be used for waterproof use of pipelines penetrating roofs or building surfaces or wall surfaces. The self-waterproof casing pipe convenient to install is mainly composed of a steel casing pipe, a steel water stop ring, a waterproof rubber ring and a waterproof cover. According to the main work principle and the installation method, when concrete is poured to the wall of a water pool, the steel casing pipe and the steel water stop ring are embedded in concrete, when the concrete reaches certain strength, the pipeline needed for penetrating penetrates the steel casing pipe, then the waterproof rubber ring is arranged on the pipeline in a sleeving manner from top to bottom, the conical face of the waterproof rubber ring is tightly attached to the oblique face of the steel casing pipe, then the pipeline penetrates a hole in the waterproof cover from top to bottom, the waterproof cover is screwed, the upper surface of the waterproof rubber ring is pressed step by step through the waterproof cover, the waterproof rubber ring moves downwards step by step, the conical face of the waterproof rubber ring and the oblique face of the steel casing pipe are pressed tightly, and installation work is finished.

Description

technical field [0001] The invention is mainly used for waterproofing pipelines passing through pool walls in the field of construction engineering, and can also be used for waterproofing pipelines passing through roofs, floors or walls. Background technique [0002] The currently used casings for pipes passing through the pool wall do not have the self-waterproof function, and need to be waterproofed separately. The waterproof effect is not ideal, and it is labor-intensive and time-consuming. Contents of the invention [0003] The present invention overcomes the above-mentioned defects, and it has good waterproof effect and quick and convenient installation; it is mainly composed of a steel casing (1), a steel water stop ring (2), a waterproof rubber ring (3), and a waterproof cover (4); the steel sleeve The upper part of the pipe (1) has an external thread (9), the inner side of the upper end of the steel sleeve (1) has an inclined surface (8), the steel water stop ring ...
