Description
Technical Field
[0001] This utility model relates to the field of building drainage technology, and in particular to a drainage structure for basement roof slabs. Background Technology
[0002] The basement roof slab is an important horizontal component connecting the basement to the above-ground structure. It plays multiple roles in the building structure system and has a critical impact on the safety, usability, and durability of the building.
[0003] The most widely used basement roof drainage structure is a combination of slope, drainage blind ditch, drainage hole, and sump. In the slope layer, the roof structure itself creates a slope or lightweight materials are laid on top of the waterproof layer to guide surface water and seepage water in the soil to the drainage blind ditch or drainage hole. The drainage blind ditch is buried in the soil layer of the roof to collect seepage water and surface runoff. Water is laterally guided to the drainage hole or sump through the gaps inside the blind ditch. The drainage hole is set at the end of the blind ditch or the lowest point of the roof, penetrating the soil layer, insulation layer, and waterproof layer of the roof. The water collected by the blind ditch is directed into the drainage ditch below the roof. Drainage ditches are set below the roof corresponding to the location of the drainage hole to collect the water discharged from the drainage hole into the sump, and then discharged to the outdoor municipal pipe network through a submersible pump or gravity drainage.
[0004] In existing drainage structures, drainage ditches and drainage holes are easily blocked by soil particles, plant roots, or debris. Blockage can lead to a sharp drop in drainage capacity. Furthermore, being buried deep in the topsoil layer, cleaning is difficult and costly. Drainage holes penetrate multiple structural layers, and if the connection between them and the waterproofing layer is not properly sealed, it can easily become a point of leakage. Rainwater may seep into the basement along the hole walls, and the leakage points are hidden and difficult to repair. The entire structure relies on gravity for water flow. If the slope layer is constructed incorrectly or if there is subsequent settlement, the slope will change, resulting in local water accumulation. Long-term water accumulation will accelerate the aging of the waterproofing layer and damage the roof structure. When facing short-term heavy rainstorms, the drainage rate of drainage ditches and drainage holes is limited, and the topsoil layer is prone to forming a saturated water layer, which increases the water pressure and may break through the waterproofing layer or crush weak parts of the roof, causing leakage or structural safety risks. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a drainage structure for basement roof slabs, which aims to improve the problems of easy clogging and failure, hidden dangers in waterproof joints, strong dependence on slope, and weak adaptability to extreme weather.

A one-way drain valve is fixedly connected to the bottom of the second branch pipe. A third branch pipe is fixedly connected to the rear of the stainless steel main drainage channel. A horizontal water collection pipe is fixedly connected to the bottom of the third branch pipe. A seepage water collection and protection component is fixedly connected to the left side of the horizontal water collection pipe. An ultrasonic cleaner is fixedly connected to the right side of the inner wall of the stainless steel main drainage channel. An automatic sewage valve is fixedly connected to the front of the stainless steel main drainage channel. A high-pressure flushing pump is fixedly connected to the right side of the horizontal water collection pipe. A rotating nozzle is fixedly connected to the top of the inner wall of the horizontal water collection pipe. An adjustable bracket is fixedly connected to the bottom of the stainless steel main drainage channel. The adjustable bracket is fixedly connected to the bottom of the horizontal water collection pipe. As a further description of the above technical solution: The infiltration water collection and protection assembly includes a fourth branch pipe, which is fixedly connected to the left side of the horizontal water collection pipe. An infiltration collection box is fixedly connected to the bottom of the fourth branch pipe. A water level sensor is fixedly connected to the right side of the inner wall of the infiltration collection box. A filter screen is fixedly connected to the top of the infiltration collection box. A root barrier screen is fixedly connected to the left side of the infiltration collection box. As a further description of the above technical solution: A ring-shaped baffle plate is fixedly connected to the right side of the self-cleaning rotating filter screen, and a drive motor is fixedly connected to the right side of the ring-shaped baffle plate. As a further description of the above technical solution: A corrugated pipe is fixedly connected to the bottom of the fourth branch pipe, and the corrugated pipe is fixedly connected to the top of the infiltration collection box. A soil particle filter is fixedly connected to the inner wall of the corrugated pipe. As a further description of the above technical solution: A slope sensor is fixedly connected to the top of the stainless steel main drainage channel. As a further description of the above technical solution: An emergency drainage pump is fixedly connected to the bottom of the one-way drainage valve, and an emergency drainage pipe is fixedly connected to the right side of the emergency drainage pump. As a further description of the above technical solution: A waterproof sleeve is fixedly connected to the outside of the No. 1 diversion pipe, the waterproof sleeve is fixedly connected to the outside of the No. 2 diversion pipe, and the waterproof sleeve is fixedly connected to the outside of the No. 3 diversion pipe. As a further description of the above technical solution: A square water-stop wing ring is fixedly connected to the outside of the waterproof sleeve.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the filter grid at the top of the stainless steel main drainage channel can intercept large particles of impurities. The self-cleaning rotating filter screen in the No. 1 diversion pipe rotates continuously under the drive of the motor. Combined with the high-frequency cleaning of the inner wall of the main drainage channel by the ultrasonic cleaner, it can effectively prevent impurities from adhering and accumulating. At the same time, the automatic drain valve can periodically discharge the deposited dirt. The rotating nozzle on the horizontal water collection pipe can perform all-round flushing of the inside of the pipe under the action of the high-pressure flushing pump, which greatly reduces the risk of drainage failure caused by blockage.
[0008] 2. In this utility model, the structure adopts a multi-layer waterproof protection design. Each diversion pipe is wrapped with a waterproof sleeve. The square water-stop wing ring on the outside can enhance the sealing effect by increasing the contact area, effectively preventing water from seeping into the structural gaps. In addition, the fixed connection nodes of the stainless steel main drainage channel and each pipe adopt an integrated sealing process. Combined with the root barrier net around the seepage collection box, it can not only prevent plant roots from damaging the waterproof layer, but also discharge the trace seepage water in time through the seepage water collection and protection components, eliminating the risk of water leakage at pipe joints and wall penetrations in traditional drainage systems from the source.
[0009] 3. In this utility model, the multi-dimensional drainage path design reduces the reliance on a single slope. The adjustable bracket at the bottom of the stainless steel main drainage channel can flexibly adjust the installation angle, and the slope sensor at the top monitors the tilt status in real time, making it easy to adjust the drainage slope according to the actual terrain. At the same time, the horizontal water collection pipe connected to the No. 3 diversion pipe forms a horizontal drainage network. The infiltration collection box is connected to the No. 4 branch pipe through a corrugated pipe, which can adapt to seepage points at different heights. This allows the drainage system to achieve efficient drainage through multi-directional water flow guidance even when the slope is small or the local flatness is insufficient.
[0010] 4. In this utility model, the one-way drain valve at the bottom of the No. 2 diversion pipe can prevent backflow. The emergency drain pump and emergency drain pipe connected to it form a backup drainage channel, which will automatically start when the main drainage system is overloaded, quickly improving the drainage capacity. The water level sensor in the infiltration collection box can monitor the water accumulation in real time. When the rainfall exceeds the normal drainage capacity, it can link the emergency system to open all drainage paths. In addition, the reinforced sealing design of the waterproof sleeve and the square water-stop wing ring can maintain stable waterproof performance when the water pressure increases suddenly due to heavy rain, ensuring the reliable operation of the drainage system under extreme weather conditions.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only one system embodiment of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0014] Reference Figures 1-8This utility model provides an embodiment of a basement roof drainage structure, including a stainless steel main drainage channel 1. As the core hub of the entire drainage system, the stainless steel main drainage channel 1 bears the crucial responsibility of collecting and transporting accumulated water from the basement roof. Made of high-strength stainless steel, it not only resists corrosion from long-term immersion but also withstands the pressure from above the roof, ensuring structural stability. Its wide cross-section design provides ample space for rapid drainage, efficiently diverting large areas of accumulated water and preventing puddles. Simultaneously, it connects various branch pipes and auxiliary equipment, orderly integrating water flows from different sources, which is fundamental to ensuring the efficient operation of the drainage system. A branch pipe is fixedly connected to the left side of the stainless steel main drainage channel 1. Diversion pipe 2, also known as the No. 1 diversion pipe 2, primarily functions to divert some of the accumulated water in the main drainage ditch, reducing the drainage pressure on the main ditch and achieving a reasonable distribution of drainage load. Its diameter is precisely calculated to ensure good flow matching with the main drainage ditch. The pipe body is made of corrosion-resistant material, adaptable to the complex and humid environment of a basement. Its fixed connection to the main drainage ditch is secure and reliable, effectively preventing leakage at the connection point and ensuring a stable and efficient diversion process, allowing accumulated water to drain faster. Diversion pipe 6 is fixedly connected to the right side of the stainless steel main drainage ditch 1. Together with diversion pipe 2, diversion pipe 6 forms a two-way diversion system, further optimizing the drainage path. It guides the accumulated water in the main drainage ditch to the right, diverting a portion of it. The drainage pressure ensures a more balanced water flow distribution throughout the drainage system. The installation angle and pipe diameter are scientifically designed to guarantee a moderate water flow velocity, preventing both excessively slow flow leading to impurity buildup and excessively fast flow causing pipe wear. A filter grille 3 is fixedly connected to the top of the stainless steel main drainage channel 1. This filter grille 3 serves as the first line of defense for the drainage system. Made of high-strength metal, its carefully designed spacing effectively intercepts larger debris such as fallen leaves, branches, and stones, preventing them from entering the main drainage channel and subsequent pipes and causing blockages. Simultaneously, the perforated structure of the filter grille 3 does not impede the rapid inflow of water, and its smooth surface facilitates cleaning and maintenance, ensuring optimal drainage. To ensure the continued effectiveness of the initial filtration stage, a self-cleaning rotating filter screen 4 is fixedly connected to the inner wall of the first diversion pipe 2. This screen primarily filters fine impurities in the water, such as sediment and fibers. Unlike ordinary filters, it has a self-cleaning function. A built-in rotating device drives the screen to rotate, and the impurities adhering to the screen are washed away by the water flow, preventing clogging and ensuring proper drainage. This design reduces the frequency of manual cleaning, improves the lifespan and filtration efficiency of the filter screen, and ensures unobstructed drainage from the first diversion pipe 2. A one-way drain valve 8 is fixedly connected to the bottom of the second diversion pipe 6. The core function of the one-way drain valve 8 is to control the unidirectional flow of water, allowing only water to drain downwards from the second diversion pipe 6, preventing backflow. When the drainage system stops working or the external water level is higher than the water level inside the pipe, the one-way drain valve 8 closes quickly, effectively preventing backflow.To protect the drainage system from external water interference and maintain its normal operation, a No. 3 diversion pipe 9 is fixedly connected to the rear of the stainless steel main drainage channel 1. A horizontal water collection pipe 10 is fixedly connected to the bottom of the No. 3 diversion pipe 9. The No. 3 diversion pipe 9 is responsible for diverting some of the accumulated water from the main drainage channel into the horizontal water collection pipe 10, thus expanding the coverage area of the drainage system. This allows water that cannot be directly drained from the main drainage channel to be effectively treated through this diversion pipe. Its connection points have good sealing performance to prevent leakage. The pipe diameter matches the main drainage channel and the horizontal water collection pipe 10 to ensure smooth water flow. The horizontal water collection pipe 10 is an important pipe connecting the No. 3 diversion pipe 9 and the seepage water collection and protection component. Its main function is to collect and transport accumulated water from the No. 3 diversion pipe 9 and seepage water collected by the seepage water collection and protection component. Its horizontal distribution covers a larger drainage area, concentrating the dispersed water flow before discharging it through subsequent pipes. The pipe body is made of durable... The stainless steel main drainage channel 1 is made of corrosion-resistant material with a smooth inner wall, reducing water flow resistance and facilitating internal cleaning and maintenance, ensuring long-term stable drainage. A permeable water collection and protection component is fixedly connected to the left side of the horizontal water collection pipe 10. An ultrasonic cleaner 14 is fixedly connected to the right side of the inner wall of the stainless steel main drainage channel 1. The ultrasonic cleaner 14 uses the energy generated by high-frequency ultrasonic vibration to deeply clean the inside of the main drainage channel and related filters. Ultrasonic waves can penetrate the water layer, causing dirt and impurities attached to the channel wall and filters to vibrate and peel off, achieving efficient cleaning. This cleaning method does not require disassembly of the equipment and will not damage the drainage system. It can effectively prevent pipe blockage caused by dirt accumulation and maintain drainage efficiency. An automatic drain valve 16 is fixedly connected to the front of the stainless steel main drainage channel 1. The automatic drain valve 16 is mainly responsible for discharging the dirt and impurities deposited in the main drainage channel. It can open automatically according to the set time interval or when it receives a dirt accumulation signal detected by relevant sensors. When the drain valve is opened, the impact force of the water flow is used to discharge the sewage from the system, preventing the sewage from accumulating in the main drainage channel and clogging the pipe, keeping the main drainage channel unobstructed, and reducing the workload of manual sewage discharge. A high-pressure flushing pump 18 is fixedly connected to the right side of the horizontal water collection pipe 10. The high-pressure flushing pump 18 is a key device for cleaning the horizontal water collection pipe 10. It generates a high-pressure water flow, which is delivered through pipes to the rotating nozzle 19. The high-pressure water flow has a strong impact force, which can wash away dirt, silt, and other impurities adhering to the inner wall of the water collection pipe, thoroughly cleaning the pipe. When activated during regular maintenance or when signs of blockage appear in the pipe, it can quickly restore the smooth flow of the water collection pipe and ensure its drainage capacity. The rotating nozzle 19 is fixedly connected to the top of the inner wall of the horizontal water collection pipe 10. The rotating nozzle 19 works in conjunction with the high-pressure flushing pump 18. Driven by the high-pressure water flow, the rotating nozzle 19 can rotate at a large angle, evenly spraying the high-pressure water flow to all parts of the inner wall of the water collection pipe. This all-round flushing method ensures that every part of the inner wall of the water collection pipe is thoroughly cleaned, leaving no dead corners, improving cleaning efficiency and effectiveness, and effectively preventing the pipe from being blocked due to localized dirt accumulation.An adjustable bracket 22 is fixedly connected to the bottom of the stainless steel main drainage channel 1. The adjustable bracket 22 is fixedly connected to the bottom of the transverse water collection pipe 10. The main function of the adjustable bracket 22 is to support the structure of the entire drainage system. Its height can be adjusted according to the actual conditions of the installation site to ensure that the stainless steel main drainage channel 1 and the transverse water collection pipe 10 are in a suitable horizontal position or drainage slope, ensuring smooth drainage. At the same time, the adjustable bracket 22 enhances the stability of the system, resists external vibrations and impacts, and ensures the structural safety of the drainage system.
[0015] Reference Figure 1 and Figure 5 The seepage water collection and protection assembly includes a fourth branch pipe 11, which is an important component of the assembly. It is specifically designed to transport the seepage water collected by the seepage collection box 12 to the horizontal collection pipe 10. The design of the fourth branch pipe 11 takes into account the flow characteristics of the seepage water, with a suitable pipe diameter to ensure smooth flow. The fourth branch pipe 11 is fixedly connected to the left side of the horizontal collection pipe 10, and the seepage collection box 12 is fixedly connected to its bottom. The seepage collection box 12 is mainly used to collect seepage water from the soil; it is buried in the soil and collects the seepage water through the box. The special structure of the container collects infiltrated water from the surrounding soil. The container has a certain volume to temporarily store the infiltrated water. Its durable material can withstand soil pressure and corrosion, ensuring long-term stable collection of infiltrated water. A water level sensor 15 is fixedly connected to the right side of the inner wall of the infiltrated water collection box 12. The water level sensor 15 monitors the water level in the infiltrated water collection box 12 in real time. When the water level reaches the set upper limit, the water level sensor 15 will send a signal, indicating that the infiltrated water needs to be drained; when the water level is below the lower limit, it will also send a corresponding signal. The monitoring system enables automated control of infiltration water collection and discharge, ensuring that the infiltration collection box 12 will not overflow due to excessively high water levels, nor will it affect collection efficiency due to excessively low water levels. A filter screen 21 is fixedly connected to the top of the infiltration collection box 12. The filter screen 21 is the first filtration barrier for infiltration water entering the infiltration collection box 12. It filters out larger soil clumps, plant debris, and other impurities in the infiltration water, preventing these impurities from entering the infiltration collection box 12 and subsequent pipes. The pore size of the filter screen 21 is moderate, effectively filtering impurities without hindering the inflow rate of the infiltration water. Its material is sturdy, resistant to soil corrosion, has a long service life, and is easy to clean and maintain. A root barrier net 17 is fixedly connected to the left side of the infiltration collection box 12. The root barrier net 17 is specifically designed to prevent plant roots from invading the infiltration collection box 12. There is usually vegetation covering the top of the basement ceiling. Plant roots have a strong penetrating power. If they invade the collection box and pipes, they will cause serious blockage. The root barrier net 17 is made of high-strength, corrosion-resistant material with fine mesh, which can effectively block roots from entering, while not affecting the normal flow of infiltration water, thus protecting the stable operation of the infiltration water collection system.
[0016] Reference Figure 1 and Figure 4 A ring-shaped baffle plate 5 is fixedly connected to the right side of the self-cleaning rotating filter screen 4. It is mainly used to filter fine impurities in the water, such as silt and fibers. It has a self-cleaning function. The internal cleaning device is driven by the built-in rotating device. Under the impact of the water flow, the impurities attached to the self-cleaning rotating filter screen 4 will be washed away, avoiding the clogging of the internal cleaning device and affecting drainage. This design reduces the frequency of manual cleaning, improves service life and filtration efficiency, and ensures smooth drainage of the No. 1 diversion pipe 2. A drive motor 7 is fixedly connected to the right side of the ring-shaped baffle plate 5. The drive motor 7 is the power source of the self-cleaning rotating filter screen 4. It provides a stable driving force for the rotation of the self-cleaning rotating filter screen 4. The rotation speed and time of the self-cleaning rotating filter screen 4 are controlled by a set program, so that the self-cleaning rotating filter screen 4 can perform self-cleaning operation at regular intervals. The drive motor 7 adopts a waterproof and moisture-proof design, which is suitable for the humid environment of the drainage system. It has low operating noise and low energy consumption, and can work stably for a long time, ensuring the normal function of the self-cleaning rotating filter screen 4.
[0017] Reference Figure 1 and Figure 2The bottom of the fourth branch pipe 11 is fixedly connected to a corrugated pipe 13. The corrugated pipe 13 has good flexibility and extensibility. When the soil settles or the temperature changes and the pipe is displaced, the corrugated pipe 13 can compensate for these displacements through its own expansion and contraction deformation, avoiding damage to the pipe connection due to excessive stress. At the same time, its corrugated structure can also slow down the water flow speed, which helps the sedimentation and filtration of soil particles. The corrugated pipe 13 is fixedly connected to the top of the infiltration collection box 12. A soil particle filter 20 is fixedly connected to the inner wall of the corrugated pipe 13. The soil particle filter 20 is mainly used to filter fine soil particles in the infiltration water. When the infiltration water flows through the corrugated pipe 13, it will pass through the soil particle filter 20. The filter material of the soil particle filter 20 can adsorb and intercept fine particles in the water, preventing these particles from entering the subsequent pipes and causing blockage. It has high filtration accuracy and is easy to disassemble and replace, maintaining good filtration effect for a long time and protecting downstream drainage equipment. A slope sensor 23 is fixedly connected to the top of the stainless steel main drainage channel 1. The slope sensor 23 is used to monitor changes in the slope of the main channel in real time. The slope of the drainage system is crucial to drainage efficiency. If the slope changes due to foundation settlement or other reasons, it will affect the flow rate of accumulated water. The slope sensor 23 can detect these changes in a timely manner and transmit the data to the control system so that staff can take timely adjustment measures to ensure that the main channel always maintains a good drainage slope. An emergency drainage pump 24 is fixedly connected to the bottom of the one-way drainage valve 8. An emergency drainage pipe 25 is fixedly connected to the right side of the emergency drainage pump 24. The emergency drainage pump 24 is part of the drainage system... Emergency drainage equipment is designed to prevent flooding of basements in emergencies such as heavy rain or pipe blockages that could lead to insufficient conventional drainage capacity. The emergency drainage pump 24 will automatically or manually activate to quickly pump out the water and discharge it through the emergency drainage pipe 25. It has a powerful drainage capacity, rapidly reducing water levels and preventing serious damage. The emergency drainage pipe 25 serves as the water flow channel during emergency drainage. Its large diameter accommodates the high-flow-rate demands of the emergency drainage pump 24, ensuring rapid drainage to a designated safe area. Made of high-strength materials, the emergency drainage pipe 25 has excellent pressure resistance and secure connections, preventing cracking or leakage during emergency drainage and ensuring the successful completion of the emergency drainage task.
[0018] Reference Figure 4 , Figure 7 and Figure 8A waterproof sleeve 26 is fixedly connected to the outside of the No. 1 diversion pipe 2. The main function of the waterproof sleeve 26 is to prevent water leakage between the pipe and the surrounding structure. It is tightly integrated with the pipe and the wall structure to form a waterproof barrier, which can effectively prevent groundwater and rainwater from seeping into the basement through the gaps around the pipe. The waterproof sleeve 26 is made of corrosion-resistant material and has a long service life, providing reliable waterproof protection for the installation part of the drainage pipe. The waterproof sleeve 26 is fixedly connected to the outside of the No. 2 diversion pipe 6 and the No. 3 diversion pipe 9.
[0019] Reference Figure 1 A square water-stop wing ring 27 is fixedly connected to the outside of the waterproof sleeve 26. The square water-stop wing ring 27 is an important component to enhance the waterproof effect. The square structure of the square water-stop wing ring 27 can increase the contact area with the surrounding concrete and other structures, making the seal between the waterproof sleeve 26 and the structure tighter and effectively preventing water from bypassing the waterproof sleeve 26 and penetrating. The water-stop wing ring is made of elastic material or metal material and has good water-stopping performance, further improving the waterproof reliability of the drainage pipe passing through the structure.
[0020] Working principle: Rainwater from the basement roof first collects in the stainless steel main drainage channel 1, where the top filter grille 3 intercepts large particles for primary filtration. Subsequently, the rainwater flows into the first branch pipe 2 and the second branch pipe 6. The self-cleaning rotating filter screen 4 in the first branch pipe 2, driven by the drive motor 7, works in conjunction with the annular baffle plate 5 to complete secondary filtration, intercepting smaller impurities. Simultaneously, infiltrated water from the roof is collected by the infiltration collection box 12, and after being protected by the filter screen 21 and root barrier screen 17, it enters the horizontal water collection pipe 10 through the corrugated pipe 13 with a soil particle filter 20 and the fourth branch pipe 11. During system operation, the inner wall of the stainless steel main drainage channel 1 is ultrasonically cleaned. The device 14 is cleaned regularly, and impurities are discharged through the automatic drain valve 16. The horizontal water collection pipe 10 is driven by the high-pressure flushing pump 18 to rotate the nozzle 19 for all-round flushing. The rainwater entering the second diversion pipe 6 is discharged through the one-way drain valve 8. In extreme weather, the emergency drain pump 24 accelerates drainage through the emergency drain pipe 25. During the process, the adjustable bracket 22 works with the slope sensor 23 to adjust the slope of the stainless steel main drainage channel 1. The waterproof sleeve 26 and the square water-stop wing ring 27 strengthen the waterproof seal. The water level sensor 15 in the infiltration collection box 12 is linked to regulate the drainage status. Finally, all the treated rainwater is collected through the horizontal water collection pipe 10 and the third diversion pipe 9 and discharged from the system.
