Abstract
Description
A drainage and waterproofing structure for basement through-wall pipes Technical Field
[0001] This utility model relates to the field of basement through-wall pipe technology, and in particular to a drainage and waterproof structure for basement through-wall pipes. Background Technology
[0002] Basements, as underground spaces within buildings, often require various through-wall pipes such as water supply and drainage pipes, ventilation pipes, and cable conduits to meet the building's functional needs. However, the connection points between these pipes and the walls are weak points in basement waterproofing. Improper handling can easily lead to leaks, causing structural dampness, steel corrosion, damage to interior finishes, and even affecting building safety and functionality.
[0003] A search revealed Chinese patent publication number CN222255371U, which discloses a drainage and waterproofing structure for a basement through-wall pipe, comprising: a bedding layer, a permeable retaining layer, a permeable filler, and a drainage pipe; the bedding layer is positioned below the through-wall pipe and contacts the basement side wall; the permeable retaining layer is closed and placed on the bedding layer, with one side of the permeable retaining layer contacting the basement side wall, the exterior of the permeable retaining layer contacting the backfill soil, and the interior of the permeable retaining layer filled with permeable filler; the first end of the through-wall pipe is placed inside the basement, passing through two opposite side walls of the permeable retaining layer and the permeable filler, with the second end placed inside a manhole; the first end of the drainage pipe is placed inside the permeable retaining layer and contacts its bottom, passing through the side wall of the permeable retaining layer opposite to the basement, and the second end of the drainage pipe is connected to a rainwater well. This invention not only prevents groundwater from seeping into the basement but also drains groundwater, reducing the risk of leakage from the basement through-wall pipe.
[0004] The aforementioned patent specification mentions that "the subbase is placed below the through-wall pipe, the permeable retaining layer is in a closed state, and the bottom of the permeable retaining layer is placed on the subbase. The permeable retaining layer isolates the permeable filler from the backfill soil, and the permeable retaining layer and permeable filler form a water interception zone, intercepting groundwater and preventing groundwater from entering the basement. Furthermore, the groundwater seeps through the permeable filler to the bottom of the permeable retaining layer, and is then transported to the rainwater well through the drainage pipe. In this way, it not only prevents groundwater from seeping into the basement, but also drains groundwater, achieving a 'prevention and drainage combined' effect, reducing..." The above content reduces the risk of leakage from pipes penetrating through walls in basements and solves the problem of leakage at the gaps between pipes penetrating through walls and the concrete structure of basements in existing technologies. While this reduces the risk of leakage from pipes penetrating through walls in basements, the sealing between the pipe connections and the overall wall is poor. External moisture can easily enter the basement through the connections, causing moisture to seep directly into the basement through the gaps at the connections. This weakens the waterproofing effect of the "prevention and drainage combined" system, leading to damp stains and water stains on the walls and floors, and even dripping or gushing water. Therefore, a drainage and waterproofing structure for pipes penetrating through walls in basements is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a drainage and waterproof structure for basement through-wall pipes, aiming to improve the problem that the sealing between the pipe connection and the wall of some devices in the prior art is poor, and external moisture can easily enter the basement through the connection.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A basement through-wall drainage and waterproofing structure includes a wall, an internal seepage-blocking mechanism, and external threaded connections to the wall and support bolts. A sealing box is externally threaded onto the support bolts, and a top cover is rotatably connected to the top of the sealing box. A sealing mechanism is located inside the sealing box. The seepage-blocking mechanism includes an external through-wall pipe, which is externally and fixedly connected to the interior of the wall. A water-stop ring is externally and fixedly connected to the external of the external through-wall pipe. Main connecting flanges are fixedly connected to both external sides of the external through-wall pipe, and retaining rings are fixedly connected to both internal sides of the external through-wall pipe. A blocking component is fixedly connected to the external of the retaining rings. A locking groove is formed on each adjacent side of the main connecting flange, and connecting bolts are threaded into each locking groove.
[0008] Through the above technical solution: when the drainage and waterproofing structure of the through-wall pipe in the basement is in operation, the support bolts are threaded to the wall to fix the sealing box. The top cover of the sealing box can be opened or closed by rotating the top of the sealing box. In the seepage prevention mechanism inside the wall, the through-wall pipe is fixed inside the wall. The water-stop ring prevents water from seeping along the gap between the through-wall pipe and the wall. The main connecting flange is connected by connecting bolts and locking grooves. The retaining ring and blocking component play a blocking role inside the through-wall pipe. The sealing mechanism inside the sealing box.
[0009] As a further description of the above technical solution:
[0010] The sealing mechanism includes a sealing tube, the outside of which is fixedly connected to the inside of the sealing box. A secondary connecting flange is fixedly connected to one side of the outer side of the sealing tube. A pressure ring is fixedly connected to the side of the secondary connecting flange away from the sealing tube. A groove is formed inside the sealing tube, and a plugging ring is fixedly connected to the outside of the groove.
[0011] Through the above technical solution: when the sealing mechanism is running, the sealing tube, as the core component, has an internal groove that engages with the plugging ring. The plugging ring is fixed outside the groove, forming an initial sealing barrier. The secondary connecting flange moves synchronously with the sealing tube. When the pressure ring on the side away from the sealing tube is subjected to external pressure, it transmits the pressure to the sealing tube through the secondary connecting flange, causing the sealing tube to undergo a slight deformation. This deformation causes the groove to further compress the plugging ring, enhancing the sealing effect. When the pressure is removed, the sealing tube returns to its original state, and the engagement between the groove and the plugging ring returns to its initial state.
[0012] As a further description of the above technical solution:
[0013] The sealing tube is fixedly connected to a main fixing flange on the side away from the secondary connecting flange, and the main fixing flange is internally threaded with fixing bolts.
[0014] Through the above technical solution: when the sealing mechanism is running, the sealing pipe is connected to the external structure through the main fixed flange, and the fixing bolts are threaded inside the main fixed flange to provide initial preload.
[0015] As a further description of the above technical solution:
[0016] A secondary fixing flange is threadedly connected to the other side of the fixing bolt, and a tapered tube is fixedly connected to the other side of the secondary fixing flange. A support ring is fixedly connected to the outside of the secondary fixing flange, that is, the side closest to the main fixing flange.
[0017] Through the above technical solution: when the sealing mechanism is running, the fixing bolts pass through the main fixing flange and the auxiliary fixing flange and are threadedly connected, the support ring provides support between the two flanges, and the tapered tube moves synchronously with the auxiliary fixing flange.
[0018] As a further description of the above technical solution:
[0019] The blocking assembly includes a main sealing ring, which is fixedly connected to the outside of the retaining ring, and a secondary sealing ring is fixedly connected to the outside of the main sealing ring.
[0020] Through the above technical solution: when the blocking component is running, the main sealing ring moves synchronously with the retaining ring. When subjected to external pressure, the main sealing ring undergoes elastic deformation, and the secondary sealing ring deforms synchronously outside the main sealing ring.
[0021] As a further description of the above technical solution:
[0022] The external part of the secondary sealing ring is fixedly connected to the inside of the through-wall outer pipe, and the external part of the main sealing ring is fixedly connected to the inside of the through-wall outer pipe.
[0023] Through the above technical solution: when the blocking component is running, both the main sealing ring and the secondary sealing ring are fixed inside the through-wall outer pipe. When the pressure changes, the main sealing ring and the secondary sealing ring will generate elastic deformation synchronously. The main sealing ring provides a basic sealing barrier inside, and the secondary sealing ring enhances the sealing effect outside.
[0024] As a further description of the above technical solution:
[0025] The outer support ring is supported inside the sealing tube, the outer support ring is snapped onto the outer of the plugging ring, and the outer secondary fixed flange is supported outside the main fixed flange.
[0026] Through the above technical solution: when the sealing mechanism is running, the secondary fixed flange is supported outside the main fixed flange, and is pre-tightened by the fixing bolts. The support ring is snapped into the plug ring outside and supported inside the sealing tube.
[0027] As a further description of the above technical solution:
[0028] The outer support of the pressure ring is on the inner side of the through-wall external pipe, the outer of the pressure ring is snapped onto the outer side of the secondary sealing ring, and the inner thread of the secondary connecting flange is connected to the outer side of the connecting bolt.
[0029] Through the above technical solution: when the sealing mechanism is running, the secondary connecting flange moves outside the connecting bolts through the thread, the pressure ring is supported on the inner wall of the through-wall outer pipe and engages with the secondary sealing ring, and its displacement causes the secondary sealing ring to undergo radial deformation, and the deformation of the secondary sealing ring is transmitted to the main sealing ring.
[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, the main connecting flange and the auxiliary connecting flange are connected by bolts to reliably connect the sealing pipe and the through-wall external pipe. The support bolts are threaded to connect the wall and the sealing box, which makes the sealing box firmly installed on the wall. The sealing material makes the sealing box pipe and the wall form an integral whole, isolating external moisture. This provides a protective space for the pipe connection and enhances the overall sealing performance, preventing external moisture from entering the basement through the connection.
[0032] 2. In this utility model, the fixed connection between the sealing pipe and the sealing box makes the connection between the secondary connecting flange and the main connecting flange more stable. The locking of the pressure ring and the secondary sealing ring enhances the sealing performance inside the pipe. The fixed connection between the groove and the plugging ring ensures that the plugging ring can be accurately installed and maintained in the correct position inside the sealing pipe. This solves the problem of external moisture seeping into the basement through the gap between the sealing pipe and the pipe, thereby further improving the waterproof performance of the basement through-wall pipe drainage and waterproofing structure and effectively preventing water accumulation and dampness in the basement caused by water seepage through pipe gaps.
