Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a water stopping device and method for joint seams of assembled water storage tanks. Background Art

[0002] As a water conservancy project facility, the reservoir is of great significance in ensuring water supply, promoting agricultural development, and improving the ecological environment. Although traditional reservoirs such as reinforced concrete reservoirs are durable, they have complex construction processes, high costs, poor crack resistance, and are prone to leakage. The new type of prefabricated reservoir has the advantages of simple construction, low cost, strong adaptability, and high safety factor, becoming a more modern and efficient water storage solution.

[0003] An assembled water tank is a water storage facility assembled from prefabricated submodules. It forms a water storage container by assembling the prefabricated submodules according to the design requirements. Since there are joints between two adjacent submodules when the prefabricated submodules are assembled, the joints need to be water-stopped. The traditional embedded water-stopping structure needs to be poured with concrete simultaneously with the main project, and the submodules of the assembled water tank are assembled after prefabrication, so the embedded water-stopping structure cannot be effectively applied to the assembled water tank. The traditional surface water-stopping structure is difficult to cope with the high water pressure inside the water tank. Since the water tank is used to store water resources, the inner wall of the water tank is subjected to water pressure and water flow erosion for a long time, so the surface water-stopping structure is difficult to effectively guarantee the anti-leakage performance of the joints of the water tank for a long time.

[0004] For example, the Chinese invention patent with publication number CN104762925B proposes a water-stopping structure for the seams around concrete panel dams and its construction method, which performs water-stopping treatment on the seams by arranging a combined rubber rod, a metal water-stopping strip, an anti-seepage protective cover sheet, a stainless steel strip and other components from the inside to the outside of the seams to form a surface water-stopping structure. However, it cannot be applied to reservoirs, because the water pressure and water flow of the reservoir will squeeze the anti-seepage protective cover sheet to cause it to deform, and then push the elastic edge seal open, and water will leak into the anti-seepage protective cover sheet. The two sides of the metal water-stopping strip are bonded to the concrete surface of the seam groove, and long-term use will lead to bonding failure, which will lead to poor anti-leakage and water-stopping performance of the overall structure. Another example is the Chinese invention patent with publication number CN113737728B, which proposes a surface waterproof structure for structural joints in tunnels and open channels and its construction method, which first sets a groove for riding the joint on the surface of the structural joint, and then sets a leveling layer, a support body, a filling block, an anti-seepage layer, a waterproof layer, and a backfill layer in the groove to form a surface waterproof structure. However, it cannot be applied to reservoirs because it has too many layers of structure, resulting in too many contact surfaces and more gaps. As a result, in later use, if it is subjected to the water pressure and water flow impact in the reservoir for a long time, it will cause water erosion and collapse on the contact surface, causing it to fall off, which will lead to poor anti-leakage and waterproof performance of the overall structure. Summary of the invention

[0005] In view of the above-mentioned problems, the object of the present invention is to provide a water-stopping device and method for the joints of assembled water tanks. The water-stopping structure can effectively adapt to the water pressure and water flow impact in the water tank and has better anti-leakage and water-stopping performance.

[0006] The technical solution of the present invention is: a water-stopping device for the joint seam of an assembled water tank, comprising at least one water-stopping structure, the water-stopping structure is used to be installed on two adjacent prefabricated submodules constituting the assembled water tank, there is a joint seam between the two adjacent prefabricated submodules, the water-stopping structure is used to perform water-stopping treatment on the joint seam, the water-stopping structure corresponds to the joint seam one by one, the width of the joint seam decreases from the inside of the water tank to the outside of the water tank, and the water-stopping structure comprises:

[0007] The water stop rod pipe is arranged in the joint seam along the seam length of the joint seam, and the water stop rod pipe is closely attached to the side wall of the joint seam;

[0008] A water stop strip is arranged along the seam length of the joint on the side of the prefabricated submodule where the joint is located inside the reservoir;

[0009] An arcuate belt is arranged on a side of the waterstop belt away from the joint along the belt length direction of the waterstop belt, and the inner side surface of the arcuate belt and the outer side surface of the waterstop belt form an extrusion cavity; and

[0010] The energy transmission component has one end arranged on the side of the arc-shaped belt located in the extrusion cavity, and the other end penetrates the waterstop belt and is arranged on the waterstop rod tube; the waterstop rod tube is made of flexible deformable material. When the arc-shaped belt is extruded, the energy transmission component squeezes the waterstop rod tube to move toward the side with a smaller splicing seam width, and the tubular structure of the waterstop rod tube can also undergo adaptive deformation.

[0011] Furthermore, a plurality of deformation clips are arranged on the side wall of the water stop rod tube along the tube length direction, and a first card slot is arranged on the side of the prefabricated submodule constituting the splicing seam, and the deformation clip is snapped into the first card slot. In actual use, the cooperation between the deformation clip and the first card slot simplifies the installation steps of the water stop rod tube, and the water stop rod tube only needs to be placed into the splicing seam and the deformation clip is snapped into the first card slot to complete the fixation, which reduces the difficulty and time of installation.

[0012] Furthermore, the width of the joint inside the reservoir is D1, the effective width of the arc belt projected to the water stop is D2, and the width of the water stop is D3, then the ratio of D1, D2, and D3 is 1:1.5~2.5:4~6. In actual use, since the water stop is located outside the joint, it needs to completely wrap the exposed end of the joint, and thus its width needs to be much larger than the width of the exposed end of the joint, so that the contact area between the water stop and the prefabricated submodule can be increased, and the connection firmness between the water stop and the reservoir structure can be improved, thereby enhancing the structural stability of the entire reservoir.

[0013] Furthermore, the prefabricated submodule is provided with a second card slot, which is parallel to the seam length direction of the joint; the two ends of the side surface of the water stop belt that contacts the prefabricated submodule are provided with card strips corresponding to the second card slot structure, and the card strips are clamped in the second card slot. The card strip and the second card slot effectively increase the contact area between the water stop belt and the prefabricated submodule, and extend the actual path distance from the joint seam to the end of the water stop belt, thereby increasing the water-stopping effect, and also increasing the overall strength of the joint seam, which helps to improve the structural safety of the water reservoir.

[0014] Furthermore, the cross-section of the second card slot is a right triangle. The right-angled triangle cross-section can provide good support force, making the connection between the card strip and the second card slot more stable. In addition, when the arc belt is subjected to water pressure, it moves toward the direction close to the waterstop belt, and it and the connecting end of the waterstop belt pull the waterstop belt to make the waterstop belt relatively displaced to both sides. At this time, the right angle of the right triangle can better block the relative displacement. That is, as the arc belt is affected by water pressure, the card strip contacts the right-angle side of the second card slot away from the joint more closely, effectively improving the water-stopping effect.

[0015] Furthermore, the prefabricated submodule is provided with a water stop groove, which is parallel to the seam length direction of the joint, and is located between the second slot and the joint; the two ends of the side surface of the water stop belt that contacts the prefabricated submodule are provided with water stop strips corresponding to the water stop groove, and the water stop strips are placed in the water stop groove. A continuous sealing interface can be formed to prevent water from leaking along the joint, thereby improving the overall anti-leakage performance. In addition, the water stop groove provides a fixed position for the water stop strip, making the connection between the water stop belt and the prefabricated submodule more stable and not easily displaced by external forces.

[0016] Furthermore, the water stop strip, the clamping strip, the water stop strip and the arc strip are all integrated structures. The integrated design is not only more suitable for prefabrication production in the early stage, but also reduces the steps of installing each component separately in the later stage of construction, thereby improving the construction efficiency.

[0017] Furthermore, there are multiple energy transmission components, which are spaced apart along the length of the arc-shaped belt. Multiple energy transmission components are spaced apart along the length of the arc-shaped belt, which helps to evenly distribute the pressure inside the reservoir on the arc-shaped belt to the water stop rod tube, avoiding excessive local stress and improving the bearing capacity and stability of the entire water stop system. Each of the energy transmission components includes:

[0018] The connecting rod is arranged perpendicular to the water stop belt, and the water stop belt is provided with a through hole for the connecting rod to pass through;

[0019] There are two connecting blocks, which are respectively arranged at both ends of the connecting rod; the arc belt and the water stop rod tube are both provided with docking blocks corresponding to the two connecting blocks one by one, and the connecting blocks are clamped on the docking blocks.

[0020] The connecting rod is set perpendicular to the water stop and fixed by perforation, ensuring a firm connection between the energy transmission component and the water stop, and preventing loosening or falling off due to external forces. The design of the connecting block and the docking block simplifies the installation process of the energy transmission component. Workers only need to connect the connecting block to the corresponding docking block to complete the fixation, reducing the difficulty and time of installation and improving construction efficiency.

[0021] Furthermore, the water stop structure further includes a mounting member, and the water stop strip is arranged on the prefabricated submodule through the mounting member, and the mounting member includes:

[0022] There are two installation belts, which are arranged on both sides of the water stop along the length of the joint seam;

[0023] There are multiple installation rods, and the multiple installation rods are used to connect the water stop belt and the installation belt;

[0024] Bolts for fastening the mounting straps to the prefabricated submodules.

[0025] The design of the mounting parts not only fixes the waterstop, but also increases the overall strength of the joints, helping to improve the structural safety of the reservoir.

[0026] A method for stopping water at the joints of an assembled water tank, using the water stopping device to stop water at the joints of the assembled water tank, comprising the following steps:

[0027] Assembling a plurality of prefabricated submodules to form a water storage tank having a plurality of joints;

[0028] Lay the water stop rod pipe in the joint seam along the length of the joint seam in the water reservoir, and ensure that the water stop strip is located on the joint seam;

[0029] Fix the mounting parts to the prefabricated submodules.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The present invention performs multiple water-stopping treatments on the joints of the assembled water tank through a water-stopping structure, and forms an extrusion cavity by combining a water-stopping belt and an arc-shaped belt. When the internal pressure of the water tank increases, the arc-shaped belt is compressed and transmits force through an energy transmission component, so that the water-stopping rod tube moves toward the narrower direction of the joint. Since the width of the joint decreases from the inside of the water tank to the outside of the water tank, when the water-stopping rod tube moves toward the narrower direction of the joint, it makes the contact with the side wall of the joint more closely, thereby enhancing the sealing effect and effectively preventing water penetration.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more. Example

[0041] like Figure 1 , Figure 2 A water-stopping device for the joints of an assembled water tank is shown, comprising at least one water-stopping structure 2, the water-stopping structure 2 being used to be installed on two adjacent prefabricated submodules 1 constituting the assembled water tank, a joint 10 being provided between the two adjacent prefabricated submodules 1, the water-stopping structure 2 being used to perform water-stopping treatment on the joint 10, the water-stopping structure 2 corresponding to the joint 10 one by one, the joint 10 becoming narrower in width from the inside of the water tank to the outside of the water tank. It should be noted that in actual use, the number of water-stopping structures 2 corresponds to the number of joints 10 formed between the prefabricated submodules 1, and since the number of prefabricated submodules 1 is limited by the actual volume of the water tank, it is not described in detail here.

[0042] The water stop structure 2 includes a water stop rod tube 21 , a water stop belt 22 , an arc belt 23 and an energy transmission component 24 . The waterstop rod tube 21 is arranged in the splicing seam 10 along the seam length of the splicing seam 10, and the waterstop rod tube 21 is tightly attached to the side wall of the splicing seam 10; the waterstop belt 22 is arranged on the side of the prefabricated sub-module 1 of the splicing seam 10 located inside the water reservoir along the seam length of the splicing seam 10; the arc belt 23 is arranged on the side of the waterstop belt 22 away from the splicing seam 10 along the belt length direction of the waterstop belt 22, and the inner side surface of the arc belt 23 and the outer side surface of the waterstop belt 22 constitute an extrusion cavity 230; one end of the energy transmission component 24 is arranged on the side of the arc belt 23 located in the extrusion cavity 230, and the other end passes through the waterstop belt 22 and is arranged on the waterstop rod tube 21; the waterstop rod tube 21 is made of flexible deformable material. When the arc belt 23 is extruded, the waterstop rod tube 21 is squeezed by the energy transmission component 24 to move toward the side with a smaller width of the splicing seam 10, and the tubular structure of the waterstop rod tube 21 can also undergo adaptive deformation.

[0043] By arranging the water stop rod tube 21, the water stop belt 22 and the arc belt 23 at the joint 10, a multiple water stop barrier is formed. The water stop rod tube 21 is close to the side wall of the joint 10, and the combination of the water stop belt 22 and the arc belt 23 forms an extrusion cavity. When the pressure inside the water reservoir increases, the arc belt 23 is compressed and transmits force through the energy transmission part 24, so that the water stop rod tube 21 moves in the direction of the narrower joint. Since the width of the joint 10 decreases from the inside of the water reservoir to the outside of the water reservoir, when the water stop rod tube 21 moves in the direction of the narrower joint, it makes it more closely contact with the side wall of the joint 10, enhancing the sealing effect and effectively preventing water penetration.

[0044] It should be noted that: Figure 1 As shown, there is a lumen inside the water stop rod tube 21, so that it can be deformed adaptively after being squeezed. In this embodiment, the water stop rod tube 21, the water stop belt 22, and the arc belt 23 are all made of rubber.

[0045] Preferably, Figure 2As shown, a plurality of deformation clips 210 are arranged on the side wall of the water stop rod tube 21 along the tube length direction, and a first card slot 11 is arranged on the side of the prefabricated submodule 1 constituting the joint seam 10, and the deformation clip 210 is clamped in the first card slot 11. Through the clamping of the deformation clip 210 and the first card slot 11, the water stop rod tube 21 can be firmly fixed in the joint seam 10 and is not easy to shift, thereby ensuring the overall stability of the water stop structure. In addition, the design of the deformation clip 210 makes the contact between the water stop rod tube 21 and the joint seam 10 closer, which helps to form a continuous and uniform sealing interface and further improves the anti-leakage performance. In actual use, the cooperation of the deformation clip 210 and the first card slot 11 simplifies the installation steps of the water stop rod tube 21. It is only necessary to put the water stop rod tube 21 into the joint seam 10 and clamp the deformation clip 210 into the first card slot 11 to complete the fixation, reducing the difficulty and time of installation. The deformation clamp 210 of this embodiment is a metal clamp disposed forwardly on the side wall of the water stop rod tube 21 .

[0046] Preferably, Figure 4 As shown, the width of the joint 10 in the reservoir is D1, the effective width of the arc belt 23 projected to the water stop 22 is D2, and the width of the water stop 22 is D3, then the ratio of D1, D2, and D3 is 1:1.5~2.5:4~6. In actual use, since the water stop 22 is located outside the joint 10, it needs to completely wrap the exposed end of the joint 10, and thus its width needs to be much larger than the width of the exposed end of the joint 10, so that the contact area between the water stop and the prefabricated submodule can be increased, and the connection firmness between the water stop and the reservoir structure can be improved, thereby enhancing the structural stability of the entire reservoir. And the proportional relationship between D2 and D1 ensures that the projected area of ​​the arc belt on the water stop is large enough, so that an effective pressure transmission surface can be formed inside the reservoir, so that the water stop can better withstand the pressure from the inside of the reservoir, thereby enhancing the water stopping effect. In this embodiment, the ratio of D1, D2, and D3 is preferably 1:1.5:4.

[0047] Preferably, Figure 2 , Figure 3As shown, the prefabricated submodule 1 is provided with a second slot 12, and the second slot 12 is parallel to the seam length direction of the joint 10; the two ends of the side surface where the water stop 22 contacts the prefabricated submodule 1 are provided with a clip 221 corresponding to the structure of the second slot 12, and the clip 221 is clipped in the second slot 12. The clip 221 and the second slot 12 effectively increase the contact area between the water stop 22 and the prefabricated submodule 1, and extend the actual path distance from the joint 10 to the end of the water stop 22, thereby increasing the water stop effect, and also increasing the overall strength of the joint, which helps to improve the structural safety of the reservoir. Among them, the connection method of the clip 221 and the second slot 12 allows the water stop to be slightly displaced and deformed within a certain range to adapt to the change in the width of the joint 10 or the slight displacement caused by external force, and this adaptability helps to maintain the water stop effect for a long time. In addition, the standardized design of the clip 221 and the second slot 12 is conducive to the standardized production of prefabricated submodules and water stop.

[0048] Preferably, the cross section of the second slot 12 is a right triangle. Figure 1 , Figure 2 As shown, one right-angled side of the right triangle is the side of the prefabricated submodule 1 that fits the waterstop 22, and the other right-angled side is away from the joint 10. The right-angled triangle cross-section can provide good support force, so that the connection between the clamping strip 221 and the second clamping slot 12 is more stable. In addition, when the arc-shaped belt 23 is subjected to water pressure, it moves toward the direction close to the waterstop 22, and the connection end with the waterstop 22 pulls the waterstop 22 to make the waterstop 22 relatively displaced to both sides. At this time, the right angle of the right triangle can better block the relative displacement. That is, as the arc-shaped belt 23 is affected by water pressure, the clamping strip 221 contacts the right-angled side of the second clamping slot 12 away from the joint 10 more closely, effectively improving the water-stopping effect.

[0049] Preferably, Figure 2 , Figure 3 As shown, a water stop groove 13 is provided on the prefabricated submodule 1, and the water stop groove 13 is parallel to the seam length direction of the splicing seam 10, and the water stop groove 13 is located between the second slot 12 and the splicing seam 10; water stop strips 222 corresponding to the water stop groove 13 are provided at both ends of the side surface of the water stop belt 22 that contacts the prefabricated submodule 1, and the water stop strips 222 are placed in the water stop groove 13. The water stop strips 222 are placed in the water stop groove 13 to form a continuous sealing interface, prevent water from leaking along the splicing seam, and improve the overall anti-leakage performance. In addition, the water stop groove 13 provides a fixed position for the water stop strip 222, so that the connection between the water stop belt and the prefabricated submodule is more stable and not easily displaced due to external forces.

[0050] Preferably, the water stop 22, the clamping strip 221, the water stop strip 222, and the arc strip 23 are all integrated structures. The integrated structure can ensure that the connection between the various parts is tighter, reducing the risk of water leakage caused by separation. In addition, the integrated design is not only more suitable for prefabrication production in the early stage, but also reduces the steps of installing each component separately in the later construction, thereby improving the construction efficiency. In this embodiment, the water stop 22, the clamping strip 221, the water stop strip 222, and the arc strip 23 are all made of chloroprene rubber.

[0051] Preferably, there are multiple energy transmission parts 24, and the multiple energy transmission parts 24 are distributed along the length of the arc belt 23 at intervals, and each energy transmission part 24 includes a connecting rod 241 and a connecting block 242. The connecting rod 241 is arranged perpendicular to the water stop belt 22, and a through hole for the connecting rod 241 to pass through is arranged on the water stop belt 22; there are two connecting blocks 242, which are arranged at both ends of the connecting rod 241; the arc belt 23 and the water stop rod tube 21 are both provided with docking blocks corresponding to the two connecting blocks 242, and the connecting blocks 242 are clamped on the docking blocks. In this embodiment, the energy transmission part 24 adopts a hard plastic rod.

[0052] Multiple energy transmission components 24 are distributed at intervals along the length of the arc belt 23, which helps to evenly distribute the pressure exerted on the arc belt 23 inside the water reservoir to the water stop rod tube 21, avoiding excessive local stress and improving the bearing capacity and stability of the entire water stop system. The connecting rod 241 is arranged perpendicular to the water stop belt 22 and is fixed by perforations, ensuring a firm connection between the energy transmission component and the water stop belt, and preventing loosening or falling off due to external forces. The design of the connecting block 242 and the docking block simplifies the installation process of the energy transmission component. Workers only need to connect the connecting block to the corresponding docking block to complete the fixation, reducing the difficulty and time of installation and improving construction efficiency.

[0053] Preferably, the water stop structure 2 also includes a mounting member 25, and the water stop strip 22 is arranged on the prefabricated sub-module 1 through the mounting member 25, and the mounting member 25 includes a mounting belt 251, a mounting rod 252 and a bolt 253. There are two mounting belts 251, and the two mounting belts 251 are arranged on both sides of the water stop strip 22 along the seam length direction of the joint seam 10; there are multiple mounting rods 252, and multiple mounting rods 252 are used to connect the water stop strip 22 with the mounting belt 251; the bolt 253 is used to fix the mounting belt 251 to the prefabricated sub-module 1. The mounting belt 251 can be a metal belt, and the present embodiment specifically uses a stainless steel metal belt, and the mounting rod 252 uses resin glass fiber reinforced plastic. Figure 2 , Figure 3As shown, one end of the mounting rod 252 is arranged on the mounting belt 251, and the other end passes through the clamping strip 221 and extends along the side of the water stop strip 22 that contacts the prefabricated submodule 1 to the outer position of the water stop strip 222, and the mounting rod 252 is half-embedded on the side of the water stop strip 22 at the contact point with the water stop strip 22. The clamping strip 221 is provided with a through groove for the mounting rod 252 to pass through, and the mounting rod 252 contacts and is not connected to the side wall of the through groove, that is, the clamping strip 221 can be deformed to both sides along the mounting rod 252 by external force, and at this time, the clamping strip 221 and the mounting rod 252 are relatively displaced. Two mounting belts 251 are arranged on both sides of the water stop strip 22 along the seam length direction of the splicing seam 10, and are connected to the water stop strip 22 through multiple mounting rods 252. This design enhances the fixation of the water stop strip on the splicing seam and prevents it from moving or deforming. The installation belt 251 is fixed to the prefabricated submodule 1 by bolts 253. This connection method improves the overall stability of the water stop belt. The design of the installation member 25 simplifies the installation process of the water stop belt. Workers can quickly connect the water stop belt to the installation belt 251 through the installation rod 252, and then use bolts 253 to fix the installation belt 251 on the prefabricated submodule 1, which reduces the difficulty and time of installation and improves construction efficiency. The design of the installation member 25 not only plays the role of fixing the water stop belt, but also increases the overall strength of the joint, which helps to improve the structural safety of the reservoir.

[0054] A method for water stopping the joints of an assembled water tank, using the water stopping device proposed in this embodiment to water stop the joints of the assembled water tank, comprises the following steps:

[0055] Assembling a plurality of prefabricated submodules 1 to form a water reservoir having a plurality of joints 10;

[0056] The water stop rod tube 21 is matched one by one with the splicing seam 10 and arranged in the splicing seam 10 along the seam length of the splicing seam 10 in the water reservoir, and the water stop strip 22 is ensured to be located on the splicing seam 10; during this period, the deformation card 210 is ensured to be engaged in the first card slot 11, the card strip 221 is arranged in the second card slot 12, and the water stop strip 222 is placed in the water stop groove 13.

[0057] The mounting member 25 is fixed to the prefabricated submodule 1 , wherein the mounting belt 251 is fixed to the prefabricated submodule 1 by means of bolts 253 .

[0058] It should be noted that: when the prefabricated submodule 1 is prefabricated in the early stage, it is necessary to reserve various notches, screw holes, etc. corresponding to the water stop structure 2. In addition, the contact surface between the water stop 22 and the prefabricated submodule 1 is further bonded and sealed with water stop glue. The side of the joint 10 facing the water reservoir is water-stopped by the water stop structure 2 proposed in this embodiment, and the joint 10 on the side outside the corresponding water reservoir can be filled by conventional means, such as foam glue filling, polyurethane foam filling, concrete filling, etc., and this embodiment uses foam glue filling.

[0059] The water stop rod tube 21 of this embodiment is close to the side wall of the joint 10, and the combination of the water stop belt 22 and the arc belt 23 forms an extrusion cavity. When the pressure inside the water reservoir increases, the arc belt 23 is deformed under pressure. On the one hand, the arc surface of the arc belt 23 moves closer to the joint 10, and then transmits force through the energy transmission part 24, so that the water stop rod tube 21 moves in the direction of the narrower joint. Since the width of the joint 10 decreases from the inside of the water reservoir to the outside of the water reservoir, when the water stop rod tube 21 moves in the direction of the narrower joint, it makes it more closely contact with the side wall of the joint 10, enhancing the sealing effect and effectively preventing water penetration.

[0060] On the other hand, the lower ends of the arc-shaped belt 23 move away from the splicing seam 10 on both sides of the splicing seam 10, causing the contact position between the waterstop belt 22 and the arc-shaped belt 23 to move away from the splicing seam 10, that is, the waterstop belt 22 is pulled toward both sides by the arc-shaped belt 23, thereby causing the clamping strip 221 to be in closer contact with the second clamping groove 12.

[0061] That is, the arc belt 23 is deformed under pressure and acts on the water stop tube 21 and the water stop belt 22 at the same time, so that the water stop tube 21 can achieve anti-leakage and water stopping inside the joint 10, and the water stop belt 22 can achieve anti-leakage and water stopping on the outside of the joint 10 in the water reservoir. The first seal on the outside of the joint 10 in the water reservoir is combined with the second seal inside the joint 10, so that the whole has a better anti-leakage and water stopping effect. Example

[0062] The difference from Example 1 is that: preferably, Figure 5 , Figure 6 As shown, a plurality of convex strips 120 are arranged in the second slot 12 of the prefabricated submodule 1 along the slot length direction, and a mounting groove 2210 corresponding to the convex strip 120 is arranged on the clamping strip 221 , and the convex strip 120 is clamped in the mounting groove 2210 .

[0063] In addition, threads are arranged on the outer wall of the mounting rod 252 of the present embodiment, and a nut is arranged on each mounting rod 252. When in use, the nut is rotated to the side close to the mounting belt 251, and the convex strip 120 is clamped in the mounting groove 2210. Then, the nut is rotated to press the side of the clamping strip 221 so that the convex strip 120 is in closer contact with the mounting groove 2210. The gap formed between the clamping strip 221 and the second clamping groove 12 after being compressed can be filled later according to the filling method proposed in Example 1.

[0064] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
