Waterproof component for pipeline to pass through floor and mounting method thereof

Abstract

The invention discloses a waterproof component for a pipeline to pass through a floor and a mounting method thereof. A gap between a working pipe and an embedded sleeve in a building floor slab is filled with factice or other flexible objects, the gap can be formed between the working pipe and the embedded sleeve after long-time use in a flexible object filling mode, and the waterproof performanceis thoroughly lost. The waterproof component comprises an outer sleeve, a cover cap and a gasket, wherein the cover cap is arranged at the upper end of the outer sleeve, the inner side wall of the cover cap is detachably connected with the outer wall of the outer sleeve, a through hole matched with a working pipe is machined in the top of the cover cap, the gasket is arranged between the cover cap and the outer sleeve, the gasket sleeves the working pipe, and an inner hole of the gasket is tightly attached to the outer wall of the working pipe.

Description

technical field [0001] The invention relates to a waterproof component and an installation method thereof, in particular to a waterproof component for a pipeline passing through a floor and an installation method thereof. Background technique [0002] There will be many vertical pipes in the building, such as water supply pipes, drainage pipes, etc., which we call work pipes. When the number of floors of the building exceeds two floors, these work pipes need to pass through the floor. The current commonly used technology The scheme is to pre-embed a casing when pouring floor concrete to form a reserved hole, and after the working pipe passes through the hole in place, the gap between the working pipe and the pre-embedded casing is filled with flexible materials such as ointment. This solution has an obvious disadvantage, that is, as time goes by, or as the working pipe vibrates, gaps will appear in the flexible material filled in the gap between the pipe and the casing, and ...

AI Technical Summary

Problems solved by technology

This solution has an obvious disadvantage, that is, as time goes by, or as the working pipe vibrates, gaps will appear in the flexible material filled in the gap between the pipe and the casing, and then the waterproof effect will be lost. Cases of water leakage between rooms are common, which can easily lead to conflicts among neighbors

In short, the filling method using flexible materials will cause gaps between the working tube and the embedded casing after long-term use, and the disadvantage of completely losing waterproof performance has not been well resolved.
