Waterproof penetration sleeve and construction method thereof

Abstract

The invention discloses a waterproof penetration sleeve and a construction method thereof. The waterproof penetration sleeve comprises a sleeve body, a wing ring, two flexible water stop rings, checkrings, connecting plates, a flexible cushion, bolt connecting pieces, reinforcing ribs and pressing holes, wherein the wing ring is connected with the sleeve body and the connecting plates in a welding manner; the check rings are connected with the sleeve body in a welding manner; the reinforcing ribs are connected with the connecting plates and the sleeve body in a welding manner; the flexible cushion is connected with the connecting plates through the bolt connecting pieces; a closed pressing space is defined by the two flexible water stop rings and the sleeve body; the flexible water stop rings are embedded in a space defined by the check rings; and the pressing holes are formed between the two flexible water stop rings. The waterproof penetration sleeve and the construction method canavoid the water seepage of a penetration part of a pipeline, can inspect the mounting quality through pressing before construction, and further ensures the safety operation of a device and a valve inan underground structure.

Description

technical field [0001] A waterproof wall-piercing sleeve and a construction method thereof, in particular to a large-diameter pipeline project in water conservancy, municipal water supply and drainage, and other industrial and mining enterprises, which can effectively prevent the wall of the groundwater structure from penetrating into the interior of the structure, ensuring that the interior of the structure Waterproof wall-piercing casing for safe operation of equipment and its construction method. Background technique [0002] In water conservancy, municipal water supply and drainage projects, and large-caliber pipelines in other industrial and mining enterprises, when the buried pipeline passes through the wall of the structure, waterproof treatment must be carried out at the place where the wall passes to prevent groundwater from seeping into the interior of the structure from the position where the pipe passes through the wall, thereby damaging the structure. Internal e...

AI Technical Summary

Problems solved by technology

[0003] First, the wall-piercing casing will periodically expand and contract due to changes in ambient temperature or internal fluid pressure. After a period of operation, there will be a gap between the sealing material, the pipe, and the casing, which cannot prevent groundwater from seeping into the structure and causing flooding of the equipment;

[0004] Second, during the pipeline installation process, when the wall-through casing and the waterproof casing are eccentric due to installation errors, the filling space of the sealing material is uneven, and the construction technology of the oil-seed-wound pipeline cannot guarantee that the wall-through pipe and the casing are completely filled. Gaps between pipes, resulting in water seepage;

[0005] Third, the existing technical means cannot inspect the construction results. Whether the water seepage at the pipe passing through the wall can only be inspected after the pipe is backfilled or during the operation of the main body of the project. It is difficult to guarantee the safe operation of the equipment and valves in the structure;

[0006] Fourth, when the diameter of the wall-penetrating pipe is large, the diameter of the wall-piercing sleeve will be larger. The production of the existing wall-piercing sleeve needs to be welded after bending and forming of steel plates, and the production process is relatively complicated;

[0007] Fifth, the existing wall-piercing sleeve is formed into a circular pipe. During the transportation process, special "meter" brackets are required to fix it, which takes up a lot of space during transportation, and increases the difficulty of transportation and transportation costs.
