Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a seepage prevention device for water supply and drainage in building engineering. Background Technology

[0002] Building installation engineering refers to the engineering process of processing, arranging, and assembling engineering raw materials in conjunction with the main project, according to the engineering construction drawings and current national engineering specifications. The installation engineering involved in the construction industry includes building water supply and drainage engineering, heating, ventilation and air conditioning engineering, electrical equipment engineering, etc. Water supply and drainage is an abbreviation for urban water supply system, drainage system, and building water supply and drainage. Water supply system is a pipeline system composed of horizontal main pipes, risers, and branch pipes, and drainage system is abbreviation for drainage system. Generally speaking, in industrial and civil buildings, water supply is a water system with external pressure, such as tap water and industrial water supply and return, while drainage is a water system that flows by its own weight and pipe slope, such as rainwater, wastewater, and sewage systems. Both water supply and drainage require the use of pipes.

[0003] During construction, holes are reserved at the locations where water supply and drainage pipes pass through when pouring concrete for later installation. After installation, cement mortar needs to be poured into the contact gaps between the pipes and the wall or floor slab to prevent leakage. Existing technologies have the following shortcomings: 1. The grout has fluidity, making it difficult to stably seal the grout within the reserved holes for solidification; 2. Grouting alone is not ideal for sealing the edges, as small gaps inevitably remain at the edge joints due to grout shrinkage during solidification, posing a significant risk of rainwater seepage into the room during heavy rainfall. Therefore, this application proposes a seepage prevention device for water supply and drainage in building engineering to address the aforementioned problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown in this embodiment, a seepage prevention device for water supply and drainage in building engineering includes a water supply and drainage pipe perforation 101 pre-reserved in the wall 100 and a pipe body 200 inserted in the water supply and drainage pipe perforation 101. The seepage prevention device body is fitted on the pipe body 200. The seepage prevention device body includes an external threaded sleeve 1. An elastic wear-resistant component that is squeezed and contacted with the outside of the pipe body 200 is installed inside the external threaded sleeve 1. The top, bottom, front and rear sides of the external threaded sleeve 1 are provided with first grouting holes 203. An internal threaded sleeve 3 is threaded on the external threaded sleeve 1. The top, bottom, front and rear sides of the internal threaded sleeve 3 are provided with second grouting holes 301. The external threaded sleeve 1 and the internal threaded sleeve 3 are both located inside the water supply and drainage pipe perforation 101. The elastic wear-resistant component is used to seal and resist wear when the right end of the pipe body 200 passes through the inside of the external threaded sleeve 1 and is squeezed and contacted with the outside.

[0024] The outer side of the external threaded sleeve 1 is fixedly fitted with a sealing assembly that is in movable contact with the left side of the wall 100. The right end of the internal threaded sleeve 3 is fixedly connected with a sealing grouting assembly that is in movable contact with the right side of the wall 100. The sealing grouting assembly is sealed and movably fitted on the pipe body 200. The sealing assembly is used to block the water supply and drainage pipe perforation 101 on the left side, and the sealing grouting assembly is used to block the water supply and drainage pipe perforation 101 on the right side. It is also used for personnel to perform grouting so that the grout enters the internal threaded sleeve 3 and the external threaded sleeve 1, and then enters the water supply and drainage pipe perforation 101 through the first grouting hole 203 and the second grouting hole 301 for solidification.

[0025] Specifically, the elastic wear-resistant component includes an elastic sealing sleeve 2 bonded inside the external threaded sleeve 1. The inner side of the elastic sealing sleeve 2 is in tight contact with the outer side of the tube body 200. Arc-shaped elastic pressure strips 202, in a taut state, are fixedly connected to the top, bottom, front, and rear inner walls of the external threaded sleeve 1. An anti-slip strip, in tight contact with the outer side of the arc-shaped elastic pressure strip 202, is bonded and fixed to the outer side of the arc-shaped elastic pressure strip 202. The inner side of the left end of the elastic sealing sleeve 2 is provided with a tapered structure 201, which facilitates insertion of the right end of the tube body 200. The sealing sleeve 2, the arc-shaped elastic pressure strip 202, and the anti-slip rubber strip work together to seal the tube body 200 when it passes through the right end. The sealing sleeve 2 and the arc-shaped elastic pressure strip 202 are squeezed and deformed outward. After the tube body 200 passes through, the four arc-shaped elastic pressure strips 202 tighten and resist wear from four directions through the four anti-slip rubber strips. The anti-slip effect of the anti-slip rubber strips is used to tighten and position the external threaded sleeve 1. This makes it easy to screw the threads of the internal threaded sleeve 3 onto the outside of the external threaded sleeve 1 when initially rotating to the left and rotating the internal threaded sleeve 3, so as to tighten both sides.

[0026] Furthermore, the sealing assembly includes a first annular sealing plate 5 fixedly sleeved on the left side of the outer side of the external threaded sleeve 1, and a first annular sealing gasket 501 that is in active contact with the left side of the wall 100 is bonded and fixed on the right side of the first annular sealing plate 5; the first annular sealing plate 5 and the first annular sealing gasket 501 cooperate to block and seal the water supply and drainage pipe perforation 101 on the left side, and the first annular sealing plate 5 is supported by the tightened external threaded sleeve 1.

[0027] Furthermore, the sealing grouting assembly includes a second annular sealing plate 4 fixedly connected to the right end of the internally threaded sleeve 3. A second annular sealing gasket, which movably contacts the right side of the wall 100, is bonded and fixed to the left side of the second annular sealing plate 4. A pull ring 402 is fixedly connected to the bottom right side of the second annular sealing plate 4. A grouting pipe 401, communicating with the inner side of the internally threaded sleeve 3, is embedded and fixed to the right side of the second annular sealing plate 4. A pipe cap is threaded onto the outer side of the right end of the grouting pipe 401. An external spiral thread is formed on the outer side of the grouting pipe 401, and an internal spiral thread that meshes with the external thread is formed on the inner side of the pipe cap. A sealing ring, movably fitted onto the outer side of the pipe body 200, is bonded and fixed to the inner side of the second annular sealing plate 4. The second annular sealing plate 4, the second annular sealing gasket, the pull ring 402, the grouting pipe 401, the pipe cap, and the sealing ring work together. By rotating the pull ring 402, the second annular sealing plate 4 is moved outside the pipe body 200. The pipe is rotated to the side, and the second annular sealing plate 4 is rotated to drive the internal threaded sleeve 3 to rotate for threaded connection. After the internal threaded sleeve 3 and the external threaded sleeve 1 are threaded and tightened on both sides, the second annular sealing plate 4 and the second annular sealing gasket are used to seal the water supply and drainage pipe perforation 101 on the right side. The pipe cover is then removed by reversing the pipe. Personnel use external grouting equipment to inject grout into the internal threaded sleeve 3 and the external threaded sleeve 1 through the grouting pipe 401. The grout is then introduced into the water supply and drainage pipe perforation 101 through the first grouting hole 203 and the second grouting hole 301 for overall solidification. By using the two-sided shielding and sealing formed by the pull, combined with the internal space grouting solidification to reinforce the sealing, a double-level sealing effect is formed, which effectively seals and stabilizes the pipe body 200 and the water supply and drainage pipe perforation 101 to prevent seepage. This avoids external rainwater from seeping into the room through the gaps in the pipe space, causing dampness and damage to the furniture.

[0028] The usage method of this embodiment is as follows: When using the seepage prevention device for water supply and drainage in building engineering, during initial installation, the external threaded sleeve 1 is inserted into the water supply and drainage pipe through hole 101, and the first annular sealing gasket 501 on the right side of the first annular sealing plate 5 is in contact with the left side of the wall 100. The right end of the pipe body 200 is passed through the external threaded sleeve 1. When the right end of the pipe body 200 is passed through the external threaded sleeve 1, it first fits and squeezes tightly against the inner side of the elastic sealing sleeve 2 to perform sealing work, and squeezes the arc-shaped elastic pressure strip 202 to make it stretch and deform outward. After the pipe body 200 passes through, the four arc-shaped elastic pressure strips 202 stretch and resist wear on the pipe body 200 from four directions through the four anti-slip rubber strips. The anti-slip effect of the anti-slip rubber strips is used to achieve the effect of stretching and positioning the external threaded sleeve 1.

[0029] Next, the second annular sealing plate 4 is placed on the pipe body 200 and pushed to the left. The second annular sealing plate 4 drives the internal threaded sleeve 3 to be inserted into the water supply and drainage pipe perforation 101 from right to left. Then, the pull ring 402 is rotated to drive the second annular sealing plate 4 to rotate outside the pipe body 200. The second annular sealing plate 4 drives the internal threaded sleeve 3 to rotate. As the internal threaded sleeve 3 rotates and moves to the left, it is gradually screwed onto the external threaded sleeve 1. Under the action of the screwing, the two sides are gradually pulled towards the middle, so that the first annular sealing gasket 501 and the second annular sealing gasket are squeezed tightly against the two sides of the wall 100 respectively. At this time, the first annular sealing plate 5 and the second annular sealing plate 4 seal and block the water supply and drainage pipe perforation 101 on both sides respectively.

[0030] Then, the pipe cap is removed by reversing the pipe. Personnel use external grouting equipment to inject grout into the internal threaded sleeve 3 and the external threaded sleeve 1 through the grouting pipe 401. The grout is then introduced into the water supply and drainage pipe perforation 101 through the first grouting hole 203 and the second grouting hole 301 for internal solidification. The pipe cap is then screwed onto the grouting pipe 401. By using the two-sided shielding and sealing formed by the pull, combined with the internal space grouting and solidification to reinforce the sealing, a double-level sealing effect is formed, achieving an effective and stable sealing and seepage prevention effect between the pipe body 200 and the water supply and drainage pipe perforation 101. This reduces the risk of external rainwater seeping into the room through small gaps in the pipe space, causing dampness and damage to the furniture, and improves the overall sealing and seepage prevention effect. Moreover, by using the shielding and sealing on both sides, the grout can be stably confined within the water supply and drainage pipe perforation 101 for solidification, preventing the phenomenon of seepage outward during the solidification process.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
