Description

Technical Field

[0001] The utility model belongs to the technical field of wall-penetrating sleeves, and in particular relates to a pipeline wall-penetrating sleeve protection structure. Background Art

[0002] Wall sleeves are also called wall-penetrating pipes, waterproof sleeves, and wall-embedded pipes. Waterproof sleeves are divided into rigid waterproof sleeves and flexible waterproof sleeves. Flexible waterproof sleeves are mainly used in places with high requirements such as civil defense walls and pools. Rigid waterproof sleeves are generally used in basements and other locations where pipes need to be passed through.

[0003] The Chinese patent with announcement number CN221610780U discloses a wall sleeve waterproof rapid sealing device, a building wall is pre-embedded with a wall sleeve, the front end of the wall sleeve is provided with a waterproof membrane, the middle part of the wall sleeve is provided with a sleeve cover plate, the sleeve cover plate includes a pipe sleeve and a flange flange plate, the pipe sleeve is located in the middle of the wall sleeve, a filling layer is provided between the wall sleeve and the pipe sleeve of the sleeve cover plate, a water pipe is provided in the pipe sleeve of the sleeve cover plate, a first waterproof layer is provided between the inner wall of the pipe sleeve and the outer wall of the water pipe, a plurality of first mounting holes are provided on the flange flange plate, the first mounting holes are all provided with bolts, a plurality of second mounting holes for cooperating with the bolts are provided on the building wall, a filling layer is provided between the sleeve cover plate and the wall sleeve, and the filling layer is made of polyurethane foam; the space between the sleeve cover plate and the wall sleeve can be quickly filled during installation to form a limit, thereby achieving the effects of waterproofing, shock absorption, heat preservation and sound insulation.

[0004] However, in actual use, since the filling layer is located on the outside of the casing cover plate and the water pipe is located on the inside of the casing cover plate, the noise, insulation effect and vibration amplitude at the water pipe will be dissipated by the casing cover plate, that is, they will be transmitted to the outside through the casing cover plate, and cannot be well absorbed by the filling layer, resulting in the wall-penetrating casing structure being not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a pipeline wall sleeve protection structure to solve the above-mentioned problem that the existing wall sleeve is not conducive to practical use.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions: a pipe wall sleeve protection structure installed in the wall, comprising

[0007] Wall sleeve, installed in the wall;

[0008] The sleeve has openings on both sides, the radial dimension of the inner wall of the sleeve is larger than the radial dimension of the openings on both sides, and the sleeve is threadedly inserted into the wall sleeve;

[0009] A water pipe is provided through the two openings, a filling cavity is provided between the outer wall of the water pipe and the inner wall of the sleeve, and a filling layer is provided in the filling cavity;

[0010] The sealing components are installed at both ends of the sleeve and are used to seal the sleeve.

[0011] The principle and effect of this technical solution:

[0012] 1. By setting a filling cavity in the sleeve and inserting the sleeve into the wall sleeve thread, the installation and positioning of the sleeve is convenient and quick, and the filling layer is located inside the sleeve and directly contacts the water pipe, which can achieve better shock absorption, heat preservation, noise reduction and other effects, and is more conducive to practical use.

[0013] 2. By arranging the sealing components on both sides of the sleeve, the sleeve can be isolated from the outside world, thereby extending the service life of the sleeve and protecting the sleeve. At the same time, the sleeve and the water pipe are sealed to achieve a waterproof effect.

[0014] The utility model is further configured as follows: the sleeve includes a fixed tube and a disassembly cover, the fixed tube is threadedly inserted into the inner side of the wall sleeve, the disassembly cover is threadedly sleeved on the end of the fixed tube, and the two openings are respectively located on the fixed tube and the disassembly cover.

[0015] The principle and effect of this technical solution: by making one side of the sleeve detachable and openable, it is easier to fill the filling cavity, that is, to install the water pipe and set the filling layer, and subsequent disassembly and maintenance are also easier, which is convenient for users to maintain and install.

[0016] The utility model is further configured as follows: the sealing assembly includes a sealing plate, which is installed on the side wall of the sleeve and sleeved on the water pipe. The sealing plate is provided with a convex ring, which is inserted into the opening.

[0017] The principle and effect of this technical solution: through the setting of the sealing plate and the convex ring, the sealing plate can block the gap between the wall sleeve and the sleeve. At the same time, the convex ring is inserted into the opening, which can make the fit between the water pipe and the opening tighter. When the water pipe is damaged, water is not easy to flow out from the gap between the water pipe and the opening, thereby achieving a sealing and waterproof effect.

[0018] The utility model is further configured as follows: a water-swelling water-stop strip is sleeved on the convex ring.

[0019] The principle and effect of this technical solution: by installing a water-expanding waterstop strip on the convex ring, when the water pipe breaks and water leaks, and the filling layer cannot effectively block water and seal, the water will come into contact with the water-expanding waterstop strip and then expand, thereby reducing the gap between the convex ring and the opening, and the convex ring and the water pipe, achieving a stable sealing effect and avoiding water overflow.

[0020] The utility model is further configured as follows: the sealing component also includes a step seat, the step seat is sleeved on the water pipe, the side wall of the step seat has an accommodating cavity, the sealing plate is adapted to the accommodating cavity, and the step seat is installed on the wall.

[0021] The principle and effect of this technical solution: by setting the step seat, the movement of the sealing plate is further restricted, while the sealing effect of the gap between the water pipe and the opening is further enhanced, and the sleeve and the sealing plate can also be protected as a whole.

[0022] The utility model is further configured as follows: a water-expanding water-stop strip is provided between the wall bushing and the sleeve.

[0023] The principle and effect of this technical solution: by setting a water-swelling waterstop strip, the broken sleeve can be blocked and repaired by the waterstop strip, thereby further improving the waterproof effect of the wall sleeve structure.

[0024] The utility model is further configured as follows: the filling layer comprises an asbestos cement segment and a linseed oil asphalt segment; the asbestos cement segments are respectively arranged on both sides of the linseed oil asphalt segment; and a water retaining ring is installed inside the linseed oil asphalt segment.

[0025] The principle and effect of this technical solution: Asbestos cement has the excellent characteristics of light weight, high strength, fire resistance, waterproof, moisture-proof, sound insulation, heat insulation, thermal insulation, corrosion resistance, insect and rodent resistance, impact resistance, easy processing, and easy decoration. Oil asphalt is waterproof, anti-corrosion, and weather-resistant. Through the setting of centralized waterproofing in the middle and functional protection on both sides, the filling layer has excellent water-releasing effect and also has fire-proof and other properties, with strong comprehensive capabilities.

[0026] The utility model is further configured such that the ratio of the thickness of the linseed asphalt segment to the thickness of the wall is 1:3.

[0027] The principle and effect of this technical solution: by limiting the ratio of the sesame asphalt segment to the wall thickness, the waterproofing, anti-corrosion and weather resistance effects of the sesame asphalt are controlled to achieve the best effect. BRIEF DESCRIPTION OF THE DRAWINGS
