Description

Technical Field

[0001] This invention relates to the field of water tank seepage prevention technology, and in particular to a water tank construction joint seepage prevention system and a construction joint seepage treatment method. Background Technology

[0002] Existing waterworks projects typically have deep water tanks, and maintenance access is usually designed below the structural joints. Because waterworks cannot shut down, any leaks at the structural joints need to be addressed promptly. However, the project is constrained by two requirements: first, the materials must have drinking water testing reports, which existing grouting materials generally cannot meet; second, the work needs to be done at the bottom of the water tank.

[0003] Regarding the above requirements, the relevant technologies have the following problems. First, grouting is used to refill the structural joints. Without cleaning the joints, the new material filling is difficult to achieve a tight seal. Cleaning the joints may worsen the leakage, making it difficult to control, and the grouting material easily contaminates the water stored in the pool. Second, sealing with new waterproofing requires pumping (which is difficult to implement in practice). If a drip tray is used, water will be lost. A drip tray plus pumping solution significantly increases the maintenance process and costs, especially considering the high electricity costs associated with pumping in traditional methods. Summary of the Invention

[0004] This invention provides a seepage prevention system and a method for treating seepage at construction joints in water tanks, which solves the problems of difficulty in repairing leaks at construction joints of tap water tanks, high construction difficulty, and high maintenance costs in the prior art.

[0005] This invention provides a leak-proof system for construction joints in water tanks, comprising: A flexible water-receiving component is fixedly installed on the structural surface where the construction joint is located and arranged along the extension direction of the construction joint, covering the entire construction joint; the flexible water-receiving component includes a water-receiving part and connecting parts located on both sides of the water-receiving part, the water-receiving part having a downwardly recessed accommodating space for collecting leaking water. A sealing connector is used to seal the connection part and fix the flexible water-receiving component to the structural surfaces on both sides of the construction joint so that the accommodating space is a closed space. The connecting pipe, the sealing connector, has its lower end connected to the accommodating space, and its upper end located outside the water tank, with the upper end's port height higher than the highest water level in the water tank, so as to use the hydrostatic pressure generated by the water column inside the connecting pipe to balance the leakage pressure at the construction joint.

[0006] According to the anti-leakage system for construction joints of water tanks provided by the present invention, a sealing part protruding towards the construction joint is provided at the connection between the water receiving part and the connecting part, and a sealing groove is provided on the structural surface on both sides of the construction joint, and the sealing part is embedded in the sealing groove to cooperate in sealing.

[0007] According to the anti-leakage system for construction joints of water tanks provided by the present invention, the sealing connector includes a pressing member and a fixing member. The pressing member is fixedly disposed on the structural surfaces on both sides of the construction joint by the fixing member. The pressing member includes a pressing part and a sealing flange. The pressing part is used to press the sealing part into the sealing groove. The sealing flange is used to contact and seal with the structural surfaces on both sides of the construction joint under pressure.

[0008] According to the anti-leakage system for construction joints of water tanks provided by the present invention, the fixing member is an expansion bolt, and an eccentric pad and a rubber gasket are provided between the clamping member and the fixing member; the clamping member is provided with an eccentric hole, and the fixing member passes through the eccentric hole to generate a clamping force biased towards one side of the sealing part when tightening.

[0009] According to the anti-leakage system for construction joints of water tanks provided by the present invention, the connecting part of the flexible water receiving component is provided with a supporting sealing protrusion so as to contact and seal with the structural surfaces on both sides of the construction joint under pressure.

[0010] According to the anti-leakage system for construction joints of water tanks provided by the present invention, the sealing connector includes a bent portion adapted to the outer contour of the crossbeam to accommodate the corner or irregular structure of the construction joint, and a connecting member is provided between adjacent sealing connectors.

[0011] The anti-leakage system for construction joints of water tanks provided by the present invention further includes a pressure plate, fasteners, and sealant. The pressure plate spans between two adjacent sealing connectors via the fasteners. The sealant fills a pre-reserved V-shaped groove between the pressure plate and the sealing connector.

[0012] According to the anti-leakage system for construction joints of water tanks provided by the present invention, at least a portion of the connecting pipe located outside the water tank is a transparent pipe, and the transparent pipe is provided with water level markings.

[0013] The present invention also provides a method for treating construction joint leakage using the aforementioned anti-leakage system for water tank construction joints, comprising the following steps: Step S10: Pre-treat the bottom walls on both sides of the construction joint to obtain the pre-treated construction surface, and open sealing grooves on the bottom walls on both sides of the construction joint. Step S20: Add a waterproof layer to the pre-treated construction surface; Step S30: Install the anti-leakage system at the construction joint using fasteners, press part of the flexible water receiving component into the sealing groove to form a sealed accommodating space, and ensure that the upper end of the connecting pipe is higher than the highest water level in the pool.

[0014] According to the construction joint leakage treatment method provided by the present invention, the step of adding a waterproof layer to the pre-treated construction surface specifically includes the following steps: Check whether the pre-treated construction surface meets the construction requirements; Once it is confirmed that the pretreated construction surface meets the construction requirements, a 1.5mm-2.5mm thick back-water pressure waterproof coating is applied to the pretreated construction surface. If the pre-treated construction surface does not meet the construction requirements, first add a 5mm-8mm thick waterproof mortar layer or epoxy mortar layer on it, and then apply the back water pressure waterproof coating.

[0015] This invention provides a seepage prevention system and a method for treating seepage at construction joints in water tanks. The system, through the combination of a accommodating space and a connecting pipe, achieves internal and external balance and stability of the seepage pressure at the leakage point within the system. Compared with traditional solutions, this solution does not require grouting or draining the water from the tank. The water's own weight cancels out the pressure of the overflowing water, achieving water stability within the system, eliminating potential leakage risks, and greatly reducing the difficulty and cost of repairing construction joints.

[0030] In related technologies, since the water tank contains drinking water, the repair of leakage at construction joints needs to meet relevant requirements. However, in actual construction, it is difficult to ensure that the construction materials will not pollute water resources. Therefore, traditional methods are difficult to implement and cannot be carried out in the presence of water.

[0031] Regarding the problems in related technologies, such as Figures 1-3As shown, this embodiment provides a seepage prevention system for construction joints in a water tank, including a flexible water receiving component 10, a sealing connector 20, and a connecting pipe 100. The flexible water receiving component 10 is fixedly installed on the structural surface where the construction joint is located and is arranged along the extension direction of the construction joint, covering the entire construction joint. The flexible water receiving component 10 includes a water receiving part and connecting parts located on both sides of the water receiving part. The water receiving part has a downwardly recessed accommodating space 13 for collecting leaked water. The sealing connector 20 is sealed to the connecting part and fixes the flexible water receiving component 10 on both sides of the structural surface of the construction joint, so that the accommodating space 13 is a closed space. The lower end of the connecting pipe 100 is connected to the accommodating space 13, and the upper end of the connecting pipe 100 is located outside the water tank, and the height of the upper end port is higher than the highest water level of the water tank, so as to use the hydrostatic pressure generated by the water column in the pipe to balance the leakage pressure at the construction joint. The water tank contains drinking water, such as tap water. Drinking water requires higher standards for subsequent maintenance and construction, and emptying the water tank is costly and complicated. In this embodiment, an independent balance system is formed by the sealed containment space 13 and the connecting pipe 100, which achieves the goal of eradicating leakage problems without affecting the normal operation of the water tank or polluting the water quality.

[0032] In this embodiment, the flexible water-receiving component 10 is fixed to the bottom wall of the structural surface where the construction joint is located. This allows for the organized collection of leaking water, which is then discharged through the connecting pipe 100. Furthermore, the outlet end of the connecting pipe 100 is positioned higher than the highest water level in the pool. This ensures that the hydrostatic pressure generated by the water in the pipe precisely balances the external water pressure at the construction joint. When the two pressures are equal, the leakage naturally stops. This fundamentally solves the problem of leakage maintenance when the tap water pool is filled with water.

[0033] Specifically, the construction joint of the pool extends along the width of the pool, such as... Figure 1 As shown in the diagram, the construction joint extends perpendicularly to the length of the pool. The flexible water-receiving component 10 is fixedly connected via a sealing connector 20. The flexible water-receiving component 10 is a one-piece molded rubber part, fixedly installed on the structural surface where the construction joint is located via the sealing connector 20, and covers the entire construction joint. For example, the flexible water-receiving component 10 can be made of ethylene propylene diene monomer (EPDM) rubber or natural rubber. One end of the connecting pipe 100 is sealed to the accommodating space 13. Seepage water within the accommodating space 13 can flow along the connecting pipe 100 and eventually reach the same level as the pool water level. At this point, the internal and external pressure at the construction joint leakage point reaches equilibrium, and leakage ceases.

[0034] Furthermore, after the flexible water-receiving component 10 is connected to the structural surface at the location of the construction joint via the sealing connector 20, the accommodating space 13 within the flexible water-receiving component 10 becomes a sealed space, which is connected to the connecting pipe 100. During sealing, since the flexible water-receiving component 10 is made of a flexible material, when connected via the sealing connector 20, it contacts the bottom wall of the structural surface where the construction joint is located, and the sealing connector 20 can compress the structure of the part of the flexible water-receiving component 10 in contact with the structural surface, thereby achieving a seal in the sealed space. Of course, the overall sealing structure of the accommodating space 13 can be found in the subsequent description.

[0035] Understandably, compared to traditional methods of addressing leaks at construction joints by constructing new waterproof structures or sealing them, this embodiment creates a sealed containment space 13 at the bottom of the construction joint and connects it to the containment space 13 via a connecting pipe 100, forming a system that balances leakage pressure and fundamentally solves the leakage problem. In particular, for tap water tanks, this anti-leakage system can efficiently and cost-effectively solve leakage problems.

[0036] In some embodiments, such as Figure 1 , Figure 2 As shown, the flexible water receiving component 10 has a sealing part 11 protruding towards the construction joint at the connection between the water receiving part and the connecting part. Correspondingly, sealing grooves 30 are provided on the structural surfaces on both sides of the construction joint. The sealing part 11 is embedded in the sealing groove 30 to form a seal. The sealing performance of the flexible water receiving component 10 directly affects the reliability of the entire system. In this embodiment, the cooperation between the sealing part 11 and the sealing groove 30 constructs the first sealing structure, improving the reliability of the seal.

[0037] Specifically, the flexible water receiving component 10 is made of a flexible material (such as the rubber material provided above). When the sealing connector 20 connects the flexible water receiving component 10 to the bottom wall of the joint, it applies a certain pressure to the flexible sealing component, so that the sealing part 11 in the flexible water receiving component 10 can be embedded in the sealing groove 30, thereby realizing the cooperation between the sealing part 11 and the sealing groove 30 to form the first sealing structure.

[0038] In a specific configuration, at least a portion of the width of the sealing part 11 is slightly larger than the width of the sealing groove 30. This causes the sealing part 11 to compress the sealing groove 30 during the process of being embedded into the sealing groove 30, thereby deforming the sealing part 11 to fill the sealing groove 30 and achieving the first seal of the accommodating space 13.

[0039] In a specific implementation, the sealing groove 30 can be precisely cut on the cleaned structural surface using a water drill or cutting machine. The depth and width must match the dimensions of the sealing part 11, with the depth generally controlled between 10mm and 20mm to ensure that the structural steel reinforcement is not damaged. The cross-sectional shape of the sealing part 11 can be trapezoidal, semi-circular, or rectangular, with a trapezoidal shape being the preferred option. The trapezoidal groove is easy to guide into the groove during installation and provides better filling effect under pressure.

[0040] In conjunction with the above embodiments, such as Figure 2 As shown, the connecting part of the flexible water receiving component 10 is provided with a supporting sealing protrusion 12, which contacts and seals with the structural surfaces on both sides of the construction joint under pressure. The sealing performance between the flexible water receiving component 10 and the structural surface where the construction joint is located directly affects the sealing performance of the accommodating space 13. In this embodiment, the supporting sealing protrusion 12 and the structural surface where the construction joint is located are sealed together, thereby forming a second sealing structure, which further improves the reliability of the sealing of the accommodating space 13.

[0041] In a specific configuration, the water receiving part is an arc-shaped water receiving structure. On both sides of the transverse cross section of the water receiving part are the sealing part 11 and the connecting part, respectively. The connecting part is connected to the sealing connector 20 by bolts. The sealing connector 20 is a metal part.

[0042] Among them, the supporting sealing protrusion 12 protrudes towards the construction joint after installation, so that a protruding sealing side is formed on both sides of the flexible water receiving part 10. When the sealing connector 20 connects the flexible connector to the structural surface on both sides of the construction joint, the flexible water receiving part 10 is under pressure, so that the sealing side abuts against the bottom wall of the structural surface, and a certain amount of deformation is generated at the contact abutment to form a second sealing structure.

[0043] Understandably, the setting of the supporting sealing protrusion 12 gives the flexible water receiving part 10 a double sealing structure, which improves the sealing performance of the accommodating space 13 and ensures the stability of the entire system.

[0044] In conjunction with the above embodiments, the sealing connector 20 includes a pressing member 21 and a fixing member 22. The pressing member 21 is fixedly disposed on the structural surfaces on both sides of the construction joint by the fixing member 22. The pressing member 21 includes a pressing part 211 and a sealing flange 212. The pressing part 211 is used to press the sealing part 11 into the sealing groove 30, and the sealing flange 212 is used to contact and seal with the structural surfaces on both sides of the construction joint under pressure. The reliability of the fit between the sealing part 11 and the sealing groove 30 directly affects the airtightness of the accommodating space 13. In this embodiment, the pressing member 21 can continuously maintain pressure on the sealing part 11, thereby effectively improving the reliability of the fit between the seal and the sealing groove 30.

[0045] Furthermore, by constructing a sealing flange 212 on the upper part of the clamping member 21, a third sealing structure is formed by the sealing flange 212 cooperating with the structural surfaces on both sides of the construction joint, which further improves the reliability of the system.

[0046] Specifically, the clamping member 21 is preferably made of aluminum alloy or stainless steel profile, integrally extruded by a mold, and has the advantages of high strength and corrosion resistance. One side wall of the clamping part 211 is inclined, while the sealing flange 212 is vertical. A horizontal connecting section connects the clamping part 211 and the sealing flange 212, making the overall structure of the clamping member 21 roughly U-shaped. A connecting groove 24 is provided on the sealing flange 212, and a sealing strip is provided within the connecting groove 24, thus forming a third sealing structure that can contact and seal with the structural surfaces on both sides of the construction joint. One end of the clamping part 211 contacts the sealing part 11 and applies pressure to the sealing part 11, so that the flexible water-receiving component 10 is under pressure.

[0047] It is understandable that a single sealing structure may fail in some special scenarios. In this embodiment, as mentioned above, a three-seal structure is set. The use of multiple sealing structures can effectively avoid the problem of poor reliability of a single sealing structure.

[0048] In the above embodiment, the fixing member 22 is an expansion bolt, and an eccentric pad 40 and a rubber gasket 50 are provided between the clamping member 21 and the fixing member 22. The clamping member 21 is provided with an eccentric hole 213, and the fixing member 22 passes through the eccentric hole 213 to generate a clamping force biased towards one side of the sealing part 11 during tightening. The direction of the clamping force can strengthen the pressure state of the sealing part 11, thereby improving the sealing performance of the accommodating space 13. In this embodiment, through the eccentric pad 40 and the eccentric hole 213, the tightening force of the fixing member 22 can be converted into an eccentric force with an eccentric direction, thereby strengthening the pressure state of the sealing part 11.

[0049] Specifically, the eccentric pad 40 is a wedge-shaped pad. When the expansion bolt is tightened, the eccentric pad 40 rotates around the bolt, thereby applying an oblique pressure to the clamping member 21, directed towards the sealing part 11. This force ensures that the sealing part 11 can be pressed into the sealing groove 30 most effectively. At the same time, the rubber gasket 50 plays a role in buffering and equalizing pressure, preventing stress concentration caused by hard contact between metal parts, and also compensating for minor unevenness of the mounting surface, making the force more uniform.

[0050] The offset of the center of the eccentric hole 213 relative to the geometric center of the pad is determined by mechanical calculations and experiments to ensure a better clamping angle and pressure distribution.

[0051] In some embodiments, such as Figure 3 , Figure 4As shown, the sealing connector 20 includes a bent portion 23 adapted to the outer contour of the crossbeam to accommodate the corner or irregular structure of the construction joint, and a connecting member is provided between adjacent sealing connectors 20. At some pool joints, a crossbeam is provided along the length of the pool, such as... Figure 3 As shown in the figure, the construction joint is covered in the figure and is therefore not shown. The beam will affect the maintenance of leakage. In this embodiment, the setting of the bending part 23 can achieve effective fitting, thereby improving the airtightness of the accommodating space 13.

[0052] Specifically, the sealing connector 20 includes an arc-shaped, L-shaped, or U-shaped bend 23 that adapts to the outer contour of the beam. The L-shaped bend 23 is used to handle corners with 90-degree inside or outside angles, such as the junction of the pool wall and the bottom plate. The U-shaped bend 23 is used to cover square beams or columns protruding from the structural surface, so that the sealing connector 20 can transition continuously from one side of the beam to the other. The arc-shaped bend is used to handle structural parts with circular columns or irregular curved surfaces.

[0053] It is understandable that the setting of the bending part 23 can effectively achieve the crossing of the crossbeam area, improve the adaptability of the system, and by including the crossbeam area in the accommodating space 13, the sealing performance of the accommodating space 13 can be effectively improved.

[0054] In conjunction with the above embodiments, when there is a beam structure at the construction joint, a bent sealing connector 20 is required. In this case, the leak-proof system also includes a pressure plate 70, fasteners 80, and sealant 90. The pressure plate 70 is positioned between two adjacent sealing connectors 20 via the fasteners 80; the sealant 90 fills the V-shaped groove reserved between the pressure plate 70 and the sealing connector 20. Typically, a sealing connector 20 with a bent portion 23 cannot directly span the entire beam; instead, it is combined in segments. In this embodiment, a connecting component is used to achieve the connection and sealing of adjacent sealing connectors 20, solving the problem of butt sealing between irregularly shaped and standard parts.

[0055] Specifically, the pressure plate 70 is a flat plate or slightly curved plate made of the same material as the sealing connector 20 (such as aluminum alloy or stainless steel). Its dimensions are designed to span the butt joint of two adjacent sealing connectors 20 and extend a predetermined distance to both sides to ensure sufficient coverage and compression area. Fasteners 80 are used to secure the pressure plate 70 to the sealing connector 20. Specifically, the fasteners 80 pass through predetermined mounting holes on the pressure plate 70 and are screwed into pre-drilled threaded holes on the sealing connector 20. At least two fasteners 80 are used, located on either side of the butt joint.

[0056] Before installing the pressure plate 70, a layer of sealant 90 is applied to the mating surfaces of the ends of two adjacent sealing connectors 20. After the pressure plate 70 is installed, a V-shaped groove (or trapezoidal groove) will naturally form between the end of the sealing connector 20 and the pressure plate 70. High-performance sealant 90 is then injected into this V-shaped groove to fill all gaps. The sealant 90 is a silicone sealant 90.

[0057] Understandably, by incorporating bends 23 that adapt to the outer contour of the crossbeam, this system can effectively conform to various complex structural shapes, achieving continuous coverage of the entire seepage prevention system and solving the blind spots that traditional solutions cannot handle at corners. Furthermore, the design of connecting components solves the problem of sealing the connection between irregularly shaped and standard parts. This modular design of "prefabricated irregularly shaped parts + on-site sealing connection" ensures both the quality stability of factory production and adaptability to complex on-site conditions, enabling this seepage prevention system to be widely applied to various irregularly shaped pool structures, demonstrating high versatility.

[0058] In some embodiments, such as Figure 3 As shown, to facilitate construction personnel's intuitive monitoring of the system's operating status and debugging, at least a portion of the connecting pipe 100 located outside the water tank is a transparent pipe with water level markings. In this embodiment, the transparent pipe allows workers to directly observe the water level.

[0059] Specifically, the connecting pipe 100 can be a transparent PVC pipe, and when the system is first installed or the water level in the pool changes, the water level can be precisely adjusted to the required height by adding or draining water into the pipe, ensuring the accurate establishment of balanced pressure.

[0060] like Figure 7 As shown, the present invention also provides a method for treating construction joint leakage using a waterproofing system for water tank construction joints, comprising the following steps: Step S10: Pre-treat the bottom walls on both sides of the construction joint to obtain the pre-treated construction surface, and open the sealing groove 30 on the bottom walls on both sides of the construction joint.

[0061] Specifically, during the pretreatment process, loose structures on the existing structure are cleaned up, and grooves are made on both sides of the structural joint. When making the grooves, the groove depth should be sufficient to meet the depth of the concrete cover of the steel reinforcement, and the existing steel reinforcement should not be cut.

[0062] Step S20: Add a waterproof layer 60 to the pre-treated construction surface.

[0063] Specifically, first determine if the pre-treated construction surface meets the construction requirements. If the pre-treated construction surface meets the requirements, apply a 1.5mm-2.5mm thick back-water pressure waterproof coating to the entire pre-treated construction surface to form a waterproof layer 60. If the pre-treated construction surface does not meet the construction requirements, that is, if the quality of the structural substrate is poor after testing and does not meet the construction requirements, first add a 5mm-8mm thick waterproof mortar layer or epoxy mortar layer on top as the pre-treated construction surface, and then apply the aforementioned back-water pressure waterproof coating to form a waterproof layer 60.

[0064] In a preferred embodiment, the thickness of the back-water pressure waterproof coating is about 2 mm, and the thickness of the waterproof mortar layer or epoxy mortar layer is about 7 mm.

[0065] Step S30: Install the anti-leakage system at the construction joint using the fastener 22, so that part of the flexible water receiving component 10 is pressed into the sealing groove 30 to form a sealed accommodating space 13, and ensure that the height of the upper end of the connecting pipe 100 is higher than the highest water level of the pool.

[0066] The anti-leakage system is the same as the one provided in the aforementioned embodiment, and its specific structure can be found in the previous description. When an eccentric pad is present, during the installation of the fixing member 22, the eccentric pad 40 is adjusted so that the sealing part 11 is pressed into the sealing groove 30, thereby sealing the internal accommodating space 13 of the water-receiving part in the flexible water-receiving member 10. Specifically, expansion bolts are used for installation, ensuring that the water-receiving part is directly below the construction joint, allowing leaked water to be directly collected within the accommodating space 13, thus achieving water storage.

[0067] In this system, after the sealing system is installed, the sealing part 11 and the sealing groove 30 cooperate to form the first sealing structure. The sealing connector 20, through the eccentric pad 40 and the eccentric hole 213, can apply an eccentric force to the sealing part 11, thereby strengthening the fit between the sealing part 11 and the sealing groove 30 and improving the reliability of the first sealing structure. The configuration of the eccentric pad 40 and the eccentric hole 213 can be referred to the aforementioned specific embodiment. The connecting part of the flexible water receiving component 10 has a supporting sealing protrusion 12, which abuts against the structural surfaces on both sides of the construction joint, thus forming a second sealing structure. This second sealing structure enhances the system's sealing performance.

[0068] Furthermore, the sealing connector 20 has a sealing flange 212, which abuts against the structural surfaces on both sides of the construction joint, thereby forming a third sealing structure. That is, a three-layer sealing structure is formed in the outward expansion direction from the accommodating space 13, and the three-layer sealing structure achieves effective sealing of the accommodating space 13, improving the reliability of the seal.

[0069] When the structural surface area where the construction joint is located contains folded areas such as beams, folded metal components must be used for transition while ensuring the continuity of the flexible water-receiving component 10. like Figure 3 , Figure 4 As shown, during the actual connection, there is a gap between the sealing connector 20 with the bent portion 23 and the flat part, which makes it impossible to work together, resulting in a butt joint between adjacent sealing connectors 20. Therefore, it is necessary to set a connecting member between adjacent sealing connectors 20, such as the pressure plate 70 described below, to achieve sealing between the butt sealing connectors 20 through the connecting member.

[0070] Specifically, the connecting member is a T-shaped member, such as... Figure 3 As shown, the T-shaped component is pre-pressed using bolt holes pre-drilled in the metal part. After pre-pressing, sealant is applied to the V-groove pre-drilled between the T-shaped component and the metal folded part to seal it.

[0071] Furthermore, the end of the flat sealing connector 20 (non-bending type) is designed with a beveled opening, such as... Figure 5 , Figure 6 As shown, the ends of the sealing connectors 20 on the two planes are sealed with sealant 90, as... Figure 6 As shown; thus sealing the butt joint between adjacent sealing connectors 20.

[0072] After completing the installation of the aforementioned components, and ensuring that water outlets are installed at the edges of the structure throughout the installation process, the outlets must be kept clear. Then, the connecting pipe 100 is sealed and connected. This connecting pipe converts the pressure of the leaking water into the potential energy of the water rising upwards. The height the leaking water is lifted (vertical height) plus the height corresponding to the energy consumed to overcome pipe resistance. The kinetic and potential energy cancel each other out, achieving the goal of stabilizing the leaking water in the system. Figure 2 As shown in the diagram. Compared to traditional solutions, this solution eliminates the need for grouting and draining the water tank. The water's own gravity counteracts the pressure of overflowing water, achieving water stability within the system and eliminating potential leakage.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
