Description

Technical Field

[0001] The utility model relates to the technical field of application of sleeves passing through concrete floors or concrete walls, in particular to a finished flexible sleeve of composite material. Background Art

[0002] In building construction, all kinds of pipelines are usually constructed with traditional casing when passing through concrete floors or concrete walls. Traditional casing has some defects: 1. The gap sealing of traditional casing is more dependent on the operating ability of construction workers, and the sealing process is cumbersome; 2. As the use time of traditional casing sealing materials increases, the adhesion of the material surface may gradually weaken, resulting in a decrease in its bonding strength with the substrate, which is prone to falling off, causing gaps in contact with the pipeline and causing leakage; 3. In an environment with large temperature changes, the thermal expansion coefficient of traditional casing sealing materials may be different from that of the pipeline, causing loosening or leakage at the pipeline connection.

[0004] Preferably, the sealing ring is made of silicone rubber.

[0005] Preferably, the width of the water stop ring is 3 cm.

[0006] Preferably, the inner diameter of the steel casing is 100-150 mm larger than the outer diameter of the formal pipeline.
