Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a basement wall leakage treatment system. Background Technology

[0002] When basement walls leak, the usual method involves creating grooves on both sides of the leak, drilling holes on both sides of the grooves, filling the gaps with grout, and finally applying surface waterproofing. However, this method is difficult to seal all leaks, resulting in unsatisfactory treatment. Utility Model Content

[0003] In view of this, the present invention provides a basement wall leakage treatment system to solve the problem that existing basement wall leakage treatment methods are difficult to seal all leakage points.

[0004] This utility model provides a system for treating basement exterior wall leakage, including:

[0005] Drainage board, installed on the inner surface of the basement wall;

[0006] The surface of the hydrophobic plate is provided with multiple protrusions, which are in contact with the inner surface of the basement wall.

[0007] In traditional basement exterior wall leakage treatment, grouting methods are insufficient to completely resolve seepage issues in large-area structural cold joints, while seepage through small cracks can still lead to dampness and mold growth on the inner building surface. In this application, the protrusions of the drainage board conform to the wall, providing a flow channel for the seeping water. This prevents the seepage from directly contacting the building surface, physically isolating the water from the surface and effectively avoiding direct erosion that could cause dampness, mold, or peeling. Furthermore, this application eliminates the need for extensive drilling or grooving of the wall, reducing secondary structural damage and overcoming the structural damage and increased costs associated with repeated grouting in traditional methods. When the basement wall has a system of large-area cold joints with multiple leakage points, the drainage board can seal all of them.

[0008] In one alternative implementation, there is a gap between adjacent protrusions.

[0009] In this application, the gaps provide a smooth flow path for seepage, allowing water seeping from the wall cracks to quickly and orderly converge downwards, preventing water accumulation between the drainage board and the wall. In traditional treatment methods, if seepage cannot be drained in time, it easily forms localized water accumulation, which can then seep into the building surface, leading to dampness and mold. The gaps between the protrusions ensure the continuity of water flow and reduce prolonged contact between water and the wall surface.

[0010] In one alternative implementation, it further includes:

[0011] A drainage channel is installed at the bottom inner side of the basement wall, and the drainage board is located above the drainage channel.

[0012] In this application, the drainage channel serves as a collection point for seepage, effectively gathering and discharging water guided by the drainage board into a sump or ditch, preventing water accumulation at the base of the wall. In traditional second-type exterior wall systems, drainage ditches are prone to water accumulation, leading to dampness at the base of the wall's cold joints. However, the drainage channel in this application is located at the bottom inner side of the wall, directly receiving water from the drainage board, reducing the contact time and area between water and the bottom structure of the wall, thus lowering the risk of dampness. Furthermore, the drainage channel's placement coordinates with the drainage board, allowing water to flow naturally under gravity, eliminating the need for additional power and saving costs.

[0013] In one alternative embodiment, the bottom end of the hydrophobic plate covers the drainage groove.

[0014] In this application, the bottom of the drainage board covers a drainage channel, which prevents seepage of water into the drainage channel during its flow. This ensures that all water guided by the drainage board is completely discharged through the drainage channel to a collection well or drainage ditch, preventing water from seeping into the surrounding building surface in the drainage channel. In traditional treatments, if the drainage structure is not properly connected, water can easily overflow from the joints, leading to secondary leakage.

[0015] In one alternative embodiment, the outer surface of the basement wall is provided with a waterproof layer.

[0016] In this application, the waterproof layer can prevent water from seeping into the interior of the basement walls, reducing the seepage pressure of the wall structure itself, thereby reducing the amount of seepage that needs to be treated through the inner drainage board and drainage channel from the source.

[0017] In one alternative embodiment, the waterproof layer includes a waterproof coating applied to the outer surface of the basement wall and a roll of material laid on the waterproof coating.

[0018] In this application, a double-layer waterproof structure enhances the waterproofing performance of the outer layer, providing more favorable working conditions for the inner hydrophobic system. The waterproof coating has excellent sealing and permeability, filling tiny pores and cracks on the wall surface; the roll material has strong tensile and tear resistance, resisting groundwater pressure and external environmental erosion. This double protection is better suited to complex underground environments than a single waterproofing material, reducing seepage problems caused by the failure of a single material. In traditional waterproofing layers, the splicing of roll materials and limited construction space can easily lead to incomplete waterproofing. In this application, the waterproof layer is combined with a hydrophobic board, improving the reliability of waterproofing, reducing the amount of water seeping into the wall, lightening the burden on the inner hydrophobic system, reducing the working pressure on the hydrophobic board and drainage channels, and extending their service life.

[0019] In one optional embodiment, a waterstop plate is provided inside the basement wall, and the waterstop plate is arranged along the height direction of the basement wall.

[0020] In this application, the waterstop enhances the wall structure's resistance to seepage from within, forming multiple lines of defense with the outer waterproof layer and the inner drainage system, thus improving the overall seepage prevention effect. The waterstop effectively blocks seepage from critical areas such as construction joints. In traditional systems, construction joints are high-risk areas for leakage, and the presence of cold joints easily leads to water seepage along these joints. The waterstop, positioned along its height, cuts off the seepage path along the joints, reducing the possibility of water entering the inner wall. Simultaneously, the waterstop, in conjunction with the outer waterproof layer, further reduces the risk of water penetrating the wall. Even if a small amount of water bypasses the waterstop and waterproof layer, the inner drainage board and drainage channels can promptly handle it, forming a comprehensive system. It is particularly suitable for structural cold joints that occur during concrete pouring due to the rainy season, specifically addressing cold joint leakage problems, reducing reliance on traditional grouting treatments, avoiding structural damage and increased costs caused by repeated grouting, and ensuring the integrity and stability of the wall structure.

[0021] In one alternative embodiment, the inner surface of the basement wall is provided with a building surface layer, which covers the hydrophobic board.

[0022] In this application, covering the building surface with a drainage board conceals the drainage board, maintaining the clean appearance of the basement interior and solving the aesthetic problem that could arise from exposed drainage structures in traditional treatments. Simultaneously, the building surface protects the drainage board, preventing damage from impacts and friction during daily use and extending its lifespan. In traditional treatments, the building surface directly contacts the wall, making it susceptible to damage from water seepage. In this application, the drainage board isolates the seepage from the building surface, preventing problems such as peeling, flaking, and mold growth due to moisture, thus ensuring the durability and aesthetics of the surface.

[0023] In one optional embodiment, the basement wall includes an exterior basement wall, and the waterproof layer, the drainage board, and the building surface layer are all installed on the exterior basement wall.

[0024] In this application, the waterproof layer, the drainage board, and the building surface layer are integrated into the basement exterior wall. The waterproof layer on the outside reduces water seepage, while the drainage board and drainage channel on the inside drain excess water. Combined with the protection of the building surface layer, a complete treatment system is formed, which effectively solves the problem of surface dampness caused by incomplete in-situ grouting.

[0025] In one optional embodiment, the basement wall includes an exterior basement wall and a partition wall disposed on the inside of the basement. A drainage ditch is provided between the exterior basement wall and the partition wall. The waterproof layer is disposed on the exterior basement wall, and the drainage board and the building surface layer are both disposed on the partition wall.

[0026] In this application, the waterproof layer of the basement exterior wall can prevent groundwater infiltration, while the inner partition wall is equipped with a drainage board and a building surface layer, so that even if a small amount of seepage water bypasses the waterproof layer and enters the inner side, it can be discharged in time through the drainage board of the partition wall. The drainage ditch can prevent water from accumulating between the partition wall and the basement exterior wall. In traditional systems, the base of the partition wall guide wall is prone to dampness due to water accumulation in the drainage ditch. This application, by installing a drainage board on the partition wall, can prevent water from seeping into the building surface layer. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Traditional basement exterior wall waterproofing systems mainly include two types:

[0037] like Figure 4 As shown, the first type of exterior wall system consists of an exterior waterproof layer (waterproof membrane + penetrating crystalline waterproof coating), basement exterior walls, and interior building surface treatment (generally plaster + paint).

[0038] like Figure 5 As shown, the second type of exterior wall system includes: an exterior waterproofing layer (waterproof membrane + penetrating crystalline waterproof coating), basement exterior walls, interior partition walls of the basement exterior walls, and interior building surface treatment (generally plaster + paint). Specifically, structural edge beams are installed on the structural slab of the basement exterior walls. These edge beams extend and penetrate the interior partition walls. The structural edge beams divide the interior partition walls into upper and lower sections. A partition guide wall is installed between the upper interior partition wall and the structural edge beam, and a partition guide wall is installed between the lower interior partition wall and the bottom of the basement interior. The space between the interior partition walls and the basement exterior walls can serve as a drainage ditch. The structural edge beams divide the drainage ditch into upper and lower sections, and drainage pipes are installed on the structural edge beams, connecting the upper and lower drainage ditches.

[0039] For the two basement exterior wall systems mentioned above, when structural leakage occurs in the basement exterior walls, the leakage is generally treated by grouting with waterproof materials. The main process is as follows:

[0040] Step 1: Grooving and Cleaning

[0041] Chisel grooves about 10-15cm wide and 8-10cm deep along both sides of the seepage joint, and remove concrete residue and debris from the surface of the original waterstop on the basement exterior wall.

[0042] Step 2: Fill with sealant

[0043] Fill the gap with polyurethane sealant or water-swellable sealing strips, and compact them to ensure a tight fit with the gap wall.

[0044] Step 3: Grouting reinforcement

[0045] Drill holes on both sides of the groove (hole diameter 10-12mm, depth 1 / 3-1 / 2 of the structural thickness), install grouting pipes, and inject epoxy resin or cement-based grout to fill the gaps.

[0046] Step 4: Surface waterproofing treatment

[0047] The grooves are smoothed by layering polymer waterproof mortar, and then a waterproof coating (such as JS waterproof coating) is applied to the surface to form a composite waterproof layer.

[0048] The grouting material used in the third step can be polyurethane grout or epoxy resin slurry.

[0049] For the first type of exterior wall system, grouting is generally performed on the spot at the leakage point of the basement exterior wall. For the second type of exterior wall system, grouting is generally performed at the base of the masonry guide wall.

[0050] Combining the two basement exterior wall waterproofing systems mentioned above, the existing basement exterior wall waterproofing treatment has the following construction problems:

[0051] 1. The short side length of commercially available waterproofing membrane rolls is approximately 1200mm. Exterior wall waterproofing inspections typically require splicing. The distance from the foundation pit support to the open surface of the basement exterior wall is generally 800mm-1000mm. This results in a relatively narrow clearance for membrane installation. These two construction limitations make it difficult to completely prevent groundwater seepage into the basement exterior wall waterproofing layer (waterproofing membrane + penetrating crystalline waterproofing coating). This can lead to water seepage or mold growth on the interior building surface of the basement.

[0052] 2. In southern regions, the rainy season is prolonged, making it difficult to ensure that the concrete pouring of basement exterior walls is unaffected by the rainy season. Continuous concrete pouring is also challenging to meet on-site requirements. Therefore, structural cold joints are common in most basement exterior walls. In cases of poor construction quality, large areas of structural cold joints may appear throughout the basement exterior walls. These cold joints will inevitably lead to water seepage or dampness, causing water seepage or mold growth on the inner surface of the basement building.

[0053] Based on the above two points, basement exterior wall leakage is a common and widespread construction quality problem.

[0054] The existing grouting treatment method for external wall leakage has the following disadvantages:

[0055] 1. For the first type of exterior wall system:

[0056] When structural cold joints appear in a large area, and the basement is deeply buried, traditional grouting and sealing methods cannot completely deal with all leakage points. Water seepage and dampness will still occur in some small structural cold joints, and water seepage, dampness and mold will still occur after the corresponding building surface is constructed.

[0057] 2. For the second type of exterior wall system:

[0058] First, this system itself has a masonry wall added to the exterior wall of the basement on the inside side of the basement.

[0059] Secondly, most of the water seepage from the basement exterior wall leakage points in this system will be drained away by the drainage ditch. However, a small amount of water in the drainage ditch cannot be completely drained. Over time, the cold joint at the junction of the masonry guide wall on the inner side of the basement and the basement structural slab is prone to dampness. Over time, this can easily lead to contamination and mold growth on the inner building surface of the basement.

[0060] Furthermore, since the grouting materials are all water-crystallizing or water-expanding materials, after grouting at the base of the guide wall, the grout is very likely to crystallize or foam and expand at the location of the drainage ditch water pipe, causing blockage, resulting in poor drainage in the drainage ditch, further causing water accumulation in the drainage ditch, leading to water seepage and dampness and mold on the wall surface.

[0061] 3. Traditional grouting methods for treating leaks, involving drilling and trenching, can easily cause secondary damage to the structure and widen cold joints. Furthermore, the sealing effect of the grout gradually weakens over a long period. When large-area, systemic cold joints appear in the structure, traditional grouting methods require repeated grouting at the same seepage point, resulting in high project costs.

[0062] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0063] According to embodiments of the present invention, such as Figure 1 As shown, a basement exterior wall leakage treatment system is provided, comprising:

[0064] A water-repellent board 1 is installed on the inner surface of the basement wall 2; the water-repellent board 1 can be made of plastic. The water-repellent board 1 is made of plastic and is waterproof, preventing water from penetrating. Figure 4 and Figure 5 As shown, the basement is divided into an inner and an outer side.

[0065] The surface of the hydrophobic plate 1 is provided with multiple protrusions 3, which are in contact with the inner surface of the basement wall 2. A cavity is formed between the hydrophobic plate 1, the protrusions 3, and the inner surface of the basement wall 2.

[0066] In traditional basement exterior wall leakage treatment, grouting is insufficient to completely resolve water seepage issues in large structural cold joints 8, while seepage through small cracks can still cause dampness and mold growth on the inner building surface 7. For example... Figure 2 and Figure 3 As shown in this application, the protrusions 3 of the drainage board 1 are attached to the wall, providing a flow channel for the seeping water. This allows the seeping water to remain within the channel rather than directly contacting the building surface layer 7, physically isolating the seeping water from the building surface layer 7 and effectively preventing moisture, mold, or peeling caused by direct erosion of the surface layer. Simultaneously, this application eliminates the need for extensive drilling or grooving of the wall, reducing secondary damage to the structure and overcoming the structural damage and increased costs associated with repeated construction in traditional grouting treatments. When the basement wall 2 has a series of large-area cold joints 8 with multiple leakage points, the drainage board 1 can seal all leakage points.

[0067] In one alternative embodiment, there is a gap between adjacent protrusions 3.

[0068] In this application, the gaps provide a smooth flow path for seepage, allowing water seeping from the wall cracks to quickly and orderly collect downwards, preventing water accumulation between the drainage board 1 and the wall. In traditional treatment methods, if seepage cannot be drained in time, it easily forms local water accumulation, which then seeps into the building surface layer 7, leading to dampness and mold. The gaps between the protrusions 3 ensure the continuity of water flow and reduce prolonged contact between water and the wall surface.

[0069] In one alternative implementation, it further includes:

[0070] Drainage channel 4 is located at the bottom inner side of basement wall 2, and drainage board 1 is located above drainage channel 4.

[0071] In this application, the drainage channel 4 serves as a collection point for seepage, enabling the water guided by the drainage board 1 to be collected and discharged into a sump or drainage ditch, preventing water accumulation at the bottom of the wall. In traditional second-type exterior wall systems, drainage ditches are prone to water accumulation, leading to dampness at the cold joint 8 at the base of the guide wall. However, the drainage channel 4 in this application is located at the bottom inner side of the wall, directly receiving the water from the drainage board 1, reducing the contact time and area between water and the bottom structure of the wall, and lowering the risk of dampness. Furthermore, the positioning of the drainage channel 4 complements the drainage board 1, allowing water to flow naturally under gravity, eliminating the need for additional power and saving costs.

[0072] In one alternative embodiment, the bottom end of the hydrophobic plate 1 covers the drainage groove 4.

[0073] In this application, the bottom end of the drainage board 1 covers the drainage channel 4, which prevents seepage water from exiting the drainage channel 4 during its flow into the drainage channel 4. This ensures that all water guided by the drainage board 1 is completely discharged through the drainage channel 4 to the collection well or drainage ditch, preventing water from seeping into the surrounding building surface layer 7 in the drainage channel 4. In traditional treatments, if the drainage structure is not properly connected, water may overflow from the joints, leading to secondary leakage.

[0074] Water seeping into the basement through the cold joints 8 of the basement wall 2 structure is naturally drawn downwards by gravity within the cavity and flows into the drainage channel 4. A drainage board 1 is also laid above the drainage channel 4 to prevent the collected water from rising and becoming damp. The collected water flows into a nearby collection well or drainage ditch through the drainage channel 4.

[0075] In one alternative embodiment, a waterproof layer 5 is provided on the outer surface of the basement wall 2.

[0076] In this application, the waterproof layer 5 can prevent water from seeping into the interior of the basement wall 2, reducing the seepage pressure of the wall structure itself, thereby reducing the amount of seepage that needs to be treated by the inner drainage board 1 and drainage channel 4 from the source.

[0077] In one alternative embodiment, the waterproof layer 5 includes a waterproof coating applied to the outer surface of the basement wall 2 and a roll of material laid on the waterproof coating.

[0078] In this application, a double waterproofing structure enhances the waterproofing performance of the outer layer, providing more favorable working conditions for the inner hydrophobic system. The waterproof coating has excellent sealing and permeability, filling tiny pores and cracks on the wall surface; the roll material has strong tensile and tear resistance, resisting the pressure of groundwater and the erosion of the external environment. Double protection is better suited to complex underground environments than a single waterproofing material, reducing seepage problems caused by the failure of a single material. In traditional waterproofing layers 5, the splicing of roll materials and limited construction space can easily lead to incomplete waterproofing. In this application, the waterproofing layer 5 is combined with the hydrophobic board 1, improving the reliability of waterproofing, reducing the amount of water seeping into the wall, lightening the burden on the inner hydrophobic system, reducing the working pressure on the hydrophobic board 1 and the drainage channel 4, and extending their service life.

[0079] In one optional embodiment, a waterstop 6 is provided inside the basement wall 2, and the waterstop 6 is arranged along the height direction of the basement wall 2. The waterstop 6 can be a steel plate.

[0080] In this application, the waterstop 6 enhances the anti-seepage capability from within the wall structure, forming multiple lines of defense with the outer waterproof layer 5 and the inner drainage system, thus improving the overall anti-seepage effect. The waterstop 6 effectively blocks water seepage from critical areas such as construction joints. In traditional systems, construction joints are high-risk areas for leakage, and the presence of cold joints 8 easily leads to water seepage along these joints. The waterstop 6, positioned along its height, cuts off the seepage path along the joints, reducing the possibility of water entering the inner wall. Simultaneously, the waterstop 6, in conjunction with the outer waterproof layer 5, further reduces the risk of water penetrating the wall. Even if a small amount of water bypasses the waterstop 6 and waterproof layer 5, the inner drainage board 1 and drainage channel 4 can promptly handle it, forming a comprehensive system. It is particularly suitable for structural cold joints 8 that occur during concrete pouring due to the rainy season, specifically addressing the leakage problem of cold joints 8, reducing reliance on traditional grouting treatments, avoiding structural damage and increased costs caused by repeated grouting, and ensuring the integrity and stability of the wall structure.

[0081] In one optional embodiment, the inner surface of the basement wall 2 is provided with a building surface layer 7, which covers the drainage board 1.

[0082] In this application, after the building surface layer 7 covers the drainage board 1, the drainage board 1 is not exposed, maintaining the clean appearance of the basement interior and solving the problem of aesthetic impact caused by exposed drainage structures in traditional treatments. At the same time, the building surface layer 7 protects the drainage board 1, preventing damage from collisions and friction during daily use and extending its service life. In traditional treatments, the building surface layer 7 is in direct contact with the wall and is easily damaged by water seepage. In this application, the drainage board 1 isolates water seepage from the building surface layer 7, making it less prone to peeling, flaking, and mold growth due to moisture, thus ensuring the durability and aesthetics of the surface layer.

[0083] In one optional embodiment, the basement wall 2 includes the basement exterior wall, and the waterproof layer 5, the drainage board 1, and the building surface layer 7 are all installed on the basement exterior wall.

[0084] In this application, the waterproof layer 5, the drainage board 1, and the building surface layer 7 are integrated into the basement exterior wall. The waterproof layer 5 on the outside reduces water seepage, while the drainage board 1 and drainage channel 4 on the inside drain excess water. Together with the protection of the building surface layer 7, a complete treatment system is formed, which effectively solves the problem of surface dampness caused by incomplete in-situ grouting.

[0085] In one optional embodiment, the basement wall 2 includes an outer wall of the basement and a partition wall disposed on the inner side of the basement. A drainage ditch is provided between the outer wall of the basement and the partition wall. The waterproof layer 5 is disposed on the outer wall of the basement. The drainage board 1 and the building surface layer 7 are both disposed on the partition wall.

[0086] Optionally, structural edge beams can be installed on the structural slab of the basement exterior wall. These edge beams can extend and penetrate the inner partition wall. The space between the inner partition wall and the basement exterior wall can serve as a drainage ditch. The structural edge beams divide the drainage ditch into upper and lower sections. Drainage pipes are installed on the structural edge beams, connecting the upper and lower drainage ditches. (See reference) Figure 5 The second type of exterior wall structure shown differs in that this application does not require the installation of partition walls or guide walls.

[0087] In this application, the waterproof layer 5 of the basement exterior wall can prevent groundwater infiltration, while the inner partition wall is equipped with a drainage board 1 and a building surface layer 7, so that even if a small amount of seepage water bypasses the waterproof layer 5 and enters the interior, it can be discharged in time through the drainage board 1 of the partition wall. The drainage ditch can prevent water from accumulating between the partition wall and the basement exterior wall. In traditional systems, the base of the partition wall guide wall is prone to dampness due to water accumulation in the drainage ditch. This application, by installing a drainage board 1 on the partition wall, can prevent water from seeping into the building surface layer 7.

[0088] This application relates to the application of a water-repellent board 1, commonly used as an outdoor ground waterproofing and drainage material, in the construction of the inner wall surface layer 7 of a basement exterior wall. Utilizing the impermeability and protrusions 3 of the water-repellent board 1, structural leaks (water seepage from large-area structural cold joints 8) that cannot be completely addressed by traditional structural leakage grouting methods are physically isolated from the inner wall surface layer 7 of the basement wall 2, ensuring it is not affected by water seepage and thus does not become damp or moldy.

[0089] Its beneficial effects are as follows:

[0090] 1. For the first type of basement exterior wall system, when it forms a large-area structural cold joint 8, traditional grouting methods cannot completely solve the structural leakage. This application can reduce the amount of repeated grouting work and can completely ensure that the building surface layer 7 on the inner side of the basement exterior wall at the implementation location is dry. At the same time, the wall drainage board 1 and the drainage channel 4 are all embedded in the building surface layer 7 of the wall and the ground, which does not affect the appearance of the basement building surface layer 7. The overall economic benefits are better than the traditional grouting method for treating structural leakage.

[0091] 2. For the second type of basement exterior wall system, the construction of the inner partition wall of the basement exterior wall can be completely eliminated, significantly reducing the project cost. At the same time, it solves the leakage problem when large areas of structural cold joints appear on the basement exterior wall, and completely ensures the dryness of the inner building surface layer 7 of the basement exterior wall.

[0092] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
