AI Technical Summary
Existing technologies, when sealing gaps where circulating water pipes penetrate walls, cannot both prevent groundwater leakage and restrict the slight displacement of the circulating water pipes. Furthermore, the sealing effect is not long-lasting, leading to serious water leakage that significantly impacts equipment lifespan.
The system employs a combination structure of corrugated pipes, drainage pipes, and connecting plates. The corrugated pipes are fixedly connected to the wall, the drain outlets and drainage pipes are connected to the sump, and the connecting plates are fixed to the circulating water pipes. The corrugated pipes can expand and contract to accommodate minor displacements, and the drainage pipes drain water to the sump for external discharge. The system is made of stainless steel to ensure corrosion resistance.
It achieves a long-lasting sealing effect, prevents groundwater leakage, and does not restrict minor displacement of the circulating water pipe, thus extending the service life of the equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building waterproofing technology, and in particular to a circulating water pipe through-wall structure. Background Technology
[0002] In power plants, the outdoor portion of the circulating water pipes is usually buried underground. After entering the indoor area, the circulating water pipes are generally installed in a circulating water pit below ground level. Therefore, holes need to be made in the walls separating the indoor and outdoor areas to allow the circulating water pipes to pass through. The gap between the circulating pipes and the openings needs to be sealed. This is because the elevation of the circulating water pipes is significantly lower than the ground level, and groundwater leakage will almost always occur at the sealed points. This is especially serious in power plants in the south and coastal areas where groundwater is abundant. As the facilities are built, the anti-leakage materials gradually become ineffective, and the leakage will become increasingly serious. When the leakage is severe, the indoor circulating water pit will be soaked in groundwater or seawater for a long time, affecting the service life of the equipment and pipes inside the circulating water pit.
[0003] One common sealing method involves welding a ring-shaped steel plate between the circulation pipe and the opening in the wall to seal the gap. However, the circulation pipe may move slightly due to changes in air and water temperature. Directly fixing the circulation pipe to the wall could lead to issues with pipeline safety or damage to the wall. Another common sealing method involves filling the gap between the circulation pipe and the wall opening with soft materials (such as waterproof sealant or asphalt hemp fiber). This can solve the problem of obstruction when the pipe moves slightly. However, over time, groundwater gradually seeps in, and the sealing effect will slowly diminish, requiring periodic replacement of the sealing material. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a circulating water pipe through-wall structure that can both restrict the slight displacement of the circulating water pipe and achieve a long-term sealing effect.
[0005] To solve the above-mentioned technical problems, this utility model provides a circulating water pipe through-wall structure, including a wall, a corrugated pipe, a drain pipe, a sump, a connecting plate, and a circulating water pipe. The wall is provided with a through-wall hole. One end of the corrugated pipe is fixedly connected to the inner side of the wall and communicates with the through-wall hole. The bottom of the corrugated pipe is provided with a drain outlet, which is connected to one end of the drain pipe. The other end of the drain pipe is connected to the sump. The connecting plate is fixedly mounted on the other end of the corrugated section. The connecting plate is annular. The circulating water pipe passes through the through-wall hole and the inner hole of the connecting plate in sequence. The circulating water pipe mates with the inner hole of the connecting plate and is fixedly connected to the connecting plate.
[0006] As a preferred embodiment of the present invention, the corrugated pipe includes a first connecting section, a corrugated section and a second connecting section connected in sequence. The end of the first connecting section away from the corrugated section is fixedly connected to the inner side of the wall, and the connecting plate is covered and fixed on the end of the second connecting section away from the corrugated pipe.

[0019] like Figure 1-2 As shown, a preferred embodiment of the present invention provides a circulating water pipe 6 through-wall structure, including a wall 1, a corrugated pipe 2, a drain pipe 3, a sump 4, a connecting plate 5, and a circulating water pipe 6. The wall 1 is provided with a through-wall hole 11. One end of the corrugated pipe 2 is fixedly connected to the inner side of the wall 1 (the side closer to the room) and communicates with the through-wall hole 11. Generally, the corrugated pipe 2 and the through-wall hole 11 are coaxially arranged. The inner diameter of the corrugated pipe 2 is larger than the diameter of the through-wall hole 11. The bottom of the corrugated pipe 2 is provided with a drain outlet 211, which is connected to one end of the drain pipe 3. The other end of the drain pipe 3 is connected to the sump 4. It can be understood that the sump 4 is located inside the circulating water pit. The connecting plate 5 is covered and fixed on the other end of the corrugated section 22. The connecting plate 5 is annular. The circulating water pipe 6 passes through the through-wall hole 11 and the inner hole of the connecting plate 5 in sequence. The circulating water pipe 6 is matched with the inner hole of the connecting plate 5 and fixedly connected to the connecting plate 5.
[0020] The working principle of this embodiment is as follows: one end of the corrugated pipe 2 is fixedly connected to the inner side of the wall 1 and communicates with the through hole 11. The connecting plate 5 is fixedly covered on the other end of the corrugated section 22. The connecting plate 5 is annular. The circulating water pipe 6 passes through the through hole 11 and the inner hole of the connecting plate 5 in sequence. That is, the corrugated pipe 2 plays a sealing role and can prevent groundwater from seeping into the room. The drain outlet 211 is connected to the sump 4 through the drain pipe 3, so that the water accumulated in the corrugated pipe 2 can be discharged into the sump 4 and discharged to the outdoor water treatment system by the original sewage pump of the sump 4. The connecting plate 5 is fixedly connected to the corrugated pipe 2 and the circulating water pipe 6 respectively. When the circulating water pipe 6 undergoes a slight displacement, the corrugated pipe 2 will expand and contract to adapt to the movement of the circulating water pipe 6, that is, it will not restrict the slight displacement of the circulating water pipe 6.
[0021] For example, the corrugated pipe 2 includes a first connecting section 21, a corrugated section 22 and a second connecting section 23 connected in sequence. The end of the first connecting section 21 away from the corrugated section 22 is fixedly connected to the inner side of the wall 1. The connecting plate 5 is covered and fixed on the end of the second connecting section 23 away from the corrugated pipe 2. The first connecting section 21 and the second connecting section 23 are straight pipes, so that the corrugated pipe 2 is fixedly connected to the inner side of the wall 1 and the connecting plate 5.
[0022] For example, the drain outlet 211 is located at the bottom of the first connecting section 21 so as to drain the water that seeps into the corrugated pipe 2 in a timely manner. The water collection pit 4 is located below the corrugated pipe 2, which helps to reduce the length of the drainage pipe 3 and facilitates its arrangement.
[0023] For example, a fixing plate 12 is pre-embedded on the inner side of the wall 1. The fixing plate 12 is annular and arranged around the axis of the through hole 11. The fixing plate 12 is fixedly connected to the end of the first connecting section 21 away from the corrugated section 22, thereby realizing the fixed connection between the fixing plate 12 and the end of the first connecting section 21, which facilitates a stable fixed connection.
[0024] For example, the fixing plate 12 is sealed and welded to the end of the first connecting segment 21 to achieve a fixed connection between the fixing plate 12 and the first connecting segment 21, while ensuring the sealing between the fixing plate 12 and the first connecting segment 21.
[0025] For example, the ends of the connecting plate 5 and the second connecting segment 23 are sealed and welded to achieve a fixed connection between the connecting plate 5 and the second connecting segment 23, while ensuring the sealing between the connecting plate 5 and the second connecting segment 23.
[0026] For example, the connecting plate 5 is sealed and welded to the circulating water pipe 6 to achieve a fixed connection between the connecting plate 5 and the circulating water pipe 6, while ensuring the sealing between the connecting plate 5 and the circulating water pipe 6.
[0027] For example, the corrugated pipe 2, the drainage pipe 3, and the connecting plate 5 are all made of stainless steel, which has good corrosion resistance and ensures long-term use.
[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
