Description

Technical Field

[0001] This application relates to the field of building waterproofing, and in particular to a basement waterproofing system. Background Technology

[0002] In the waterproofing and drainage design of basement projects, the interface between the waterproofing coating and the wall is prone to cracking due to thermal expansion and contraction caused by temperature changes, as well as the aging of the waterproofing coating itself over time. This cracking can lead to the formation of capillary seepage channels. Furthermore, because the drainage path is singular, the seepage water accumulated at the base of the wall cannot be effectively drained, resulting in the basement structure remaining damp for extended periods and accelerating damage to the walls and internal components.

[0003] To address the aforementioned issues, traditional basement waterproofing projects often employ a single drainage pipe. This type of pipe is typically laid directly on the construction surface, resulting in a relatively simple structure. Alternatively, waterproof membranes are used to cover basement walls and floors to prevent moisture penetration. However, in areas with high loads, such as driveways and equipment rooms, the PVC drainage pipes used in traditional systems face severe stress. The large loads acting directly on the PVC pipes can easily cause damage or deformation, and may also cause displacement, disrupting their intended drainage path and leading to a loss of drainage function, resulting in localized water accumulation. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a basement waterproofing system.

[0005] A basement waterproofing system, the basement including a wall base and a construction surface perpendicular to the wall base, the waterproofing system comprising: A drainage pipe assembly, supported on the construction surface, includes a main drainage pipe arranged near and parallel to the wall base, and multiple branch drainage pipes arranged in an array along the length of the main drainage pipe. The branch drainage pipes communicate with the main drainage pipe, and each branch drainage pipe has multiple first drain holes along its length. The limiting frame includes a limiting member for limiting the main drainage pipe and a limiting plate arranged perpendicular to the branch drainage pipe. The limiting plate includes multiple plates arranged in parallel. Each limiting plate has a U-shaped groove with an opening facing downward and cooperating with the branch drainage pipe. The limiting member and the limiting plate are both fixed to the construction surface.

[0006] By adopting the above solution, the drainage pipe assembly is subject to a large load, which can easily damage or deform it, thus losing its drainage function. At the same time, during construction, the drainage pipe assembly is easily affected by external construction disturbances, which can cause displacement and disrupt the preset drainage path. The arrangement of the main drainage pipes forms a mesh structure, which can evenly distribute the load. The setting of limiting components and limiting plates can prevent the drainage pipe assembly from shifting, thus enhancing the stability of the drainage pipe assembly. In addition, during the concrete pouring process, the drainage pipe assembly is subjected to the impact force and buoyancy of the concrete. The limiting skeleton can resist the flow impact and buoyancy of the concrete, and can also distribute the load borne by the drainage pipe assembly.

[0007] In one embodiment, the limiting member is rod-shaped with an A-shaped cross-section, and the bottom surface of the limiting member is formed with a limiting groove facing downwards, and the main drain pipe is located in the limiting groove.

[0008] By adopting the above scheme, the cross-section of the limiting component is set to an A-shape. The load on the main drain pipe is distributed to both sides of the main drain pipe by the limiting component, which avoids excessive pressure on the main drain pipe and deformation. At the same time, the limiting groove is used to limit the main drain pipe and prevent the main drain pipe from shifting.

[0009] In one embodiment, the limiting frame further includes an mounting plate with an L-shaped cross-section that covers the wall base and the construction surface, and both the limiting member and the limiting plate are fixed to the mounting plate.

[0010] By adopting the above solution, the mounting plate can prevent water from seeping to the bottom of the drainage pipe assembly, thereby causing the drainage pipe assembly to settle. At the same time, it provides an installation base point for the drainage pipe assembly and the limiting frame, ensuring the accuracy of the installation position of the drainage pipe assembly and the limiting frame. Since there is a construction joint between the wall base and the construction surface, water can easily seep into the construction joint. The mounting plate can seal the construction joint and prevent water seepage.

[0011] In one embodiment, both the limiting plate and the limiting member have insert plates at their bottoms, and the mounting plate has slots that mate with the insert plates.

[0012] By adopting the above solution, the insert plate and slot are matched to achieve splicing installation, avoiding errors caused by on-site measurement and marking, shortening the construction cycle, and improving the installation accuracy of drainage pipe assembly and limit frame.

[0013] In one embodiment, the mounting plate has a first drainage slope and a second drainage slope of the same height. The surface of the mounting plate that contacts the drainage branch pipe is the first drainage slope. The second drainage slope is located between the main drainage pipe and the wall base. The main drainage pipe has a plurality of second drainage holes along its length. Both the first drainage slope and the second drainage slope are tangent to the bottom of the main drainage pipe, and their heights are both lower than the second drainage holes.

[0014] By adopting the above scheme, the drainage slope can guide the accumulated water towards the main drainage pipe. When there is too much water, the water is guided into the main drainage pipe through the second drainage hole because the main drainage pipe has a larger volume, thus improving drainage efficiency.

[0015] In one embodiment, a drainage channel is formed between the first drainage slope and the second drainage slope. The bottom surface of the drainage channel is an inclined surface. A drainage pipe is embedded in the drainage channel. The top of the drainage pipe has a plurality of third drainage holes along its length.

[0016] By adopting the above solution, when water seeps through the main drain pipe and the mounting plate, the drain pipe can also drain the water through the third drain hole.

[0017] In one embodiment, a plurality of water guide plates are provided between two adjacent limiting plates. Each drainage branch pipe has two symmetrically arranged water guide plates that are tangent to the outer circumference of the drainage branch pipe. The side of each water guide plate away from the drainage branch pipe is higher than the side close to the drainage branch pipe.

[0018] By adopting the above solution, the water guide plate can direct the accumulated water towards the direction of the drainage branch pipe, thereby enhancing the water collection capacity of the drainage branch pipe.

[0019] In one embodiment, each of the limiting plates is provided with multiple through holes, and each of the water guide plates is provided with a rotating rod passing through the through holes on the side opposite to the drainage branch pipe. The outer wall of the drainage branch pipe is fitted with a rubber ring that mates with the inner wall of the U-shaped groove.

[0020] By adopting the above solution, since gaps may be generated between the water guide plate and the drainage branch pipe during the installation process, the water guide plate can be pressed tightly against the drainage branch pipe by rotating the rotating rod during the installation process. This avoids gaps between the water guide plate and the drainage branch pipe, and also makes the fit between the drainage branch pipe and the U-shaped groove tighter. The rubber ring not only plays a sealing role, but also plays a buffering role for the drainage branch pipe.

[0021] In one embodiment, the rotating rod is prismatic in shape, with a post at one end and a hole at the other end, the post passing through the through hole and engaging with the hole.

[0022] By adopting the above scheme, the prism shape of the rotating rod makes it easy for workers to turn the rod with a wrench. The matching of the insertion post and the insertion hole facilitates the installation of multiple rotating rods on the same straight line. In the actual processing, the matching of the insertion post and the insertion hole plays a guiding role in the installation of the water guide plate.

[0023] In one embodiment, the outer periphery of both the main drainage pipe and the branch drainage pipe is covered with geotextile.

[0024] By adopting the above scheme, the geotextile plays a filtering role for the first and second drainage holes, preventing silt from blocking the first and second drainage holes.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Because drainage pipe assemblies are subject to significant loads, they are prone to damage or deformation, resulting in loss of drainage function. Furthermore, during construction, drainage pipe assemblies are susceptible to external disturbances, causing displacement and disrupting the pre-designed drainage path. The arrangement of main drainage pipes forms a mesh structure, which evenly distributes the load. The installation of limiting components and plates prevents displacement of the drainage pipe assembly, enhancing its stability. Additionally, during concrete pouring, the drainage pipe assembly is subjected to impact and buoyancy from the concrete. The limiting frame resists the flow impact and buoyancy of the concrete, while also dispersing the load borne by the drainage pipe assembly.

[0026] 2. The mounting plate can prevent water seepage to the bottom of the drainage pipe assembly, thus preventing the drainage pipe assembly from settling. At the same time, it provides an installation base point for the drainage pipe assembly and the limiting frame, ensuring the accuracy of the installation position of the drainage pipe assembly and the limiting frame. Since there is a construction joint between the wall base and the construction surface, water can easily seep into the construction joint. The mounting plate can seal the construction joint to prevent water seepage. In addition, the insertion plate and the slot can cooperate to achieve splicing installation, avoiding the errors caused by on-site measurement and marking, shortening the construction cycle, and improving the installation accuracy of the drainage pipe assembly and the limiting frame.

[0027] 3. Since gaps may form between the water guide plate and the drainage branch pipe during installation, the rotating rod is used to press the water guide plate tightly against the drainage branch pipe during installation. This prevents gaps from forming between the water guide plate and the drainage branch pipe, and also makes the fit between the drainage branch pipe and the U-shaped groove tighter. The rubber ring plays a sealing role and also acts as a buffer for the drainage branch pipe. Attached Figure Description

[0033] Therefore, it is necessary to provide a structurally stable basement waterproofing system.

[0034] Please see Figure 1-2 , Figure 1 This is a structural schematic diagram of a basement waterproofing system provided in this application. The basement waterproofing system provided in this application includes a drainage pipe assembly 1 and a limiting frame 2. The drainage pipe assembly 1 is supported on the construction surface, and the limiting frame 2 is fixed to the construction surface to limit the drainage pipe assembly 1. This arrangement enhances the stability of the drainage pipe assembly 1, preventing it from being damaged, deformed, or displaced due to factors such as load, construction disturbance, concrete impact, and buoyancy. It ensures the smooth flow of the preset drainage path, resists the impact of concrete flow and buoyancy, and also disperses the load borne by the drainage pipe assembly 1.

[0035] The drainage pipe assembly 1 includes a main drainage pipe 11 and multiple branch drainage pipes 12. The main drainage pipe 11 is located near and parallel to the wall base 3, and is characterized by a tubular structure. It can be made of high-strength PVC or metal, possessing certain compressive strength and corrosion resistance. The branch drainage pipes 12 are arranged in an array along the length of the main drainage pipe 11 and are connected to it. Each branch drainage pipe 12 is also tubular, with multiple first drainage holes 121 along its length to guide accumulated water into the branch drainage pipe 12. The branch drainage pipes 12 can also be made of the same material as the main drainage pipe 11. The combination of the main drainage pipe 11 and the branch drainage pipes 12 forms a mesh structure, which can evenly distribute the load. In some special cases, the main drainage pipe 11 and the branch drainage pipes 12 can also use flexible pipes to adapt to different construction environments and terrain changes. The branch drainage pipes 12 are connected to the main drainage pipe 11 by welding or fittings to ensure smooth drainage.

[0036] The limiting frame 2 includes a limiting member 21, a limiting plate 22, and a mounting plate 23. The limiting member 21, used to limit the drainage main pipe 11, is rod-shaped with an A-shaped cross-section. Its bottom surface has a downward-facing limiting groove 211, within which the drainage main pipe 11 is located. This A-shaped structure distributes the load on the drainage main pipe 11 to both sides, preventing excessive pressure and deformation. The limiting member 21 can be made of steel or hard plastic, possessing high strength. The limiting plate 22 is perpendicular to the drainage branch pipe 12, comprising multiple parallel plates. Each limiting plate 22 has a downward-facing U-shaped groove 221 that engages with the drainage branch pipe 12, limiting the drainage branch pipe 12 and preventing displacement.

[0037] The limiting plate 22 can also be made of the same material as the limiting component 21. The mounting plate 23 has an L-shaped cross-section and covers the wall base 3 and the construction surface. Both the limiting component 21 and the limiting plate 22 are fixed to the mounting plate 23. The mounting plate 23 can prevent water seepage to the bottom of the drainage pipe assembly 1, preventing the drainage pipe assembly 1 from settling. At the same time, it provides an installation base point for the drainage pipe assembly 1 and the limiting frame 2, ensuring the accuracy of the installation position. The mounting plate 23 can be made of a metal plate with good waterproof performance. The limiting component 21 and the limiting plate 22 are fixed to the mounting plate 23 by bolts or welding.

[0038] Both the limiting plate 22 and the limiting component 21 have insert plates 24 at their bottom, and the mounting plate 23 has slots 231 that mate with the insert plates 24. The insert plates 24 and slots 231 work together to achieve splicing installation, avoiding errors caused by on-site measurement and marking, shortening the construction cycle, and improving the installation accuracy of the drainage pipe assembly 1 and the limiting frame 2. The shapes of the insert plates 24 and slots 231 can be designed according to actual needs, such as rectangular or trapezoidal shapes.

[0039] Mounting plate 23 has a first drainage slope 232 and a second drainage slope 233 of the same height. The surface of mounting plate 23 that contacts drainage branch pipe 12 is the first drainage slope 232. The second drainage slope 233 is located between drainage main pipe 11 and wall base 3. Drainage main pipe 11 has multiple second drainage holes 111 along its length. Both the first drainage slope 232 and the second drainage slope 233 are tangent to the bottom of drainage main pipe 11, and their heights are both lower than the second drainage holes 111. The drainage slopes can guide accumulated water to flow towards drainage main pipe 11. When there is too much accumulated water, the guided water enters drainage main pipe 11 through the second drainage holes 111, improving drainage efficiency.

[0040] In the actual construction process, the installation plate 23 located at the connection between the wall base 3 and the construction surface has an L-shaped cross section. One outer side of the installation plate 23 is completely attached to the side of the wall base 3. The first drainage slope 232 and the second drainage slope 233 of the installation plate 23 can be spliced ​​or welded from multiple plates. The bottom of the plate is filled with concrete. Then, the insert plate 24 is inserted into the slot 231. After the insert plate 24 passes through the slot 231, it is embedded in the concrete. After the concrete at the bottom of the plate solidifies, the next plate is installed.

[0041] Please refer to the following: Figure 3 , Figure 3 This is a cross-sectional view of a basement waterproofing system provided in this application. A drainage channel 234 is formed between the first drainage slope 232 and the second drainage slope 233. The bottom surface of the drainage channel 234 is sloping, and a drainage pipe 235 is embedded in the drainage channel 234. The top of the drainage pipe 235 has multiple third drainage holes 2351 along its length. When water seeps through the main drainage pipe 11 and the mounting plate 23, the drainage pipe 235 can also drain the water through the third drainage holes 2351. The material of the drainage pipe 235 can be the same as that of the main drainage pipe 11 and the branch drainage pipe 12 to ensure its drainage performance and durability.

[0042] In this application, the limiting frame 2 may not require the mounting plate 23; the limiting component 21 and the limiting plate 22 can be directly fixed to the construction surface using anchor bolts or similar methods. This configuration can be used in situations where waterproofing requirements are not particularly high or the construction environment is relatively simple, reducing the use of the mounting plate 23 and lowering costs and construction difficulty. In this case, the limiting component 21 and the limiting plate 22, directly fixed to the construction surface, can still limit the drainage pipe assembly 1, ensuring its stability. Simultaneously, the mesh structure of the main drainage pipe 11 and the branch drainage pipe 12, along with other related components, can still achieve drainage and waterproofing functions. While meeting basic waterproofing requirements, this configuration reduces costs and construction complexity, representing a certain optimization and improvement of existing technology.

[0043] Multiple water guide plates 25 are provided between two adjacent limiting plates 22. Each drainage branch pipe 12 corresponds to two symmetrically arranged water guide plates 25 that are tangent to the outer circumference of the drainage branch pipe 12. The side of each water guide plate 25 facing away from the drainage branch pipe 12 is higher than the side closest to the drainage branch pipe 12. The water guide plates 25 can guide the leaked water towards the drainage branch pipe 12, thereby enhancing the water collection capacity of the drainage branch pipe 12. At the same time, the water guide plates 25 connect multiple dispersed limiting plates 22 together, increasing the stability of the limiting frame 2 structure. The water guide plates 25 are made of metal plates.

[0044] Please refer to the following: Figure 4 , Figure 4 This is a schematic diagram showing the installation relationship between the water guide plate and the limiting plate. Each limiting plate 22 has multiple through holes 222, and each water guide plate 25 has a rotating rod 251 passing through the through holes 222 on the side opposite to the drainage branch pipe 12. The rotating rod 251 and the water guide plate 25 can be integrally formed or fixed by welding. A rubber ring 223 is fitted on the outer wall of the drainage branch pipe 12, which mates with the inner wall of the U-shaped groove 221. By rotating the rotating rod 251, the water guide plate 25 can be pressed tightly against the drainage branch pipe 12, preventing gaps from forming between the water guide plate 25 and the drainage branch pipe 12, and making the fit between the drainage branch pipe 12 and the U-shaped groove 221 tighter. The rubber ring 223 serves a sealing function and also acts as a buffer for the drainage branch pipe 12. The rotating rod 251 is prismatic in shape, with a post 2511 at one end and a hole 2512 at the other end. The post 2511 passes through the through hole 222 and engages with the hole 2512. In this application, the hole 2512 may have an internal thread, and the post 2511 has an external thread that engages with the internal thread, thereby ensuring a stable connection between the two rotating rods 251. The prismatic shape of the rotating rod 251 facilitates operation by a wrench. The engagement of the post 2511 and the hole 2512 allows multiple rotating rods 251 to be installed in a straight line. In actual processing, the engagement of the post 2511 and the hole 2512 guides the installation of the water guide plate 25.

[0045] During the installation of the water guide plate 25, after installing one limiting plate 22, insert the pin 2511 through the through hole 222, then install the next limiting plate 22, and then insert the pin 2511 of the next rotating rod 251 through the through hole 222 so that it mates with the insertion hole 2512 of the previous rotating rod 251. Next, move the rubber ring 223 fitted on the drainage branch pipe 12 to the U-shaped groove 221. Finally, use a wrench to turn the rotating rod 251 so that the water guide plate 25 rotates to abut against the drainage branch pipe 12. The water guide plate 25 applies an upward force to the drainage branch pipe 12, so that the rubber ring 223 on the outer circumference of the drainage branch pipe 12 abuts against the inner wall of the U-shaped groove 221, thereby achieving a tight connection between the drainage branch pipe 12 and the U-shaped groove 221. At the same time, the water guide plate 25 and the limiting plate 22 are fixed by welding or bolting.

[0046] In this application, both the main drainage pipe 11 and the branch drainage pipe 12 are covered with geotextile 13. The geotextile 13 acts as a filter for the first drainage hole 121 and the second drainage hole 111, preventing silt from clogging the first drainage hole 121 and the second drainage hole 111. The geotextile 13 has good permeability and filtration properties, and can effectively prevent impurities such as silt from entering the drainage pipe assembly 1.

[0047] The working principle of this application is as follows: This embodiment solves the problems of easy damage and displacement of drainage pipes in traditional basement waterproofing methods by combining drainage pipe assembly 1 and limiting frame 2. The mesh structure formed by the main drainage pipe 11 and drainage branch pipe 12 evenly distributes the load, and the limiting component 21, limiting plate 22 and mounting plate 23 of the limiting frame 2 prevent displacement of drainage pipe assembly 1 and enhance its stability. The drainage slope, drainage channel 234 and drainage pipe 235 improve drainage efficiency, the water guide plate 25 enhances the water collection capacity of drainage branch pipe 12, the swivel rod 251 and rubber ring 223 ensure tight fit between components, and the geotextile 13 prevents drainage holes from being blocked. The synergistic effect of these structures makes the basement waterproofing system more stable and efficient, and has made a significant improvement and contribution to the existing technology.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
