Description

Technical Field

[0001] This utility model belongs to the field of sleeve sealing technology, specifically relating to a sleeve structure for sealing concrete water tanks. Background Technology

[0002] In wastewater treatment systems, the USAB (Up-flow Anaerobic Sludge Bed) anaerobic tank plays a crucial role. The normal operation of the anaerobic tank has a decisive impact on the decomposition and treatment of pollutants in wastewater, and leakage is not allowed.

[0003] During the construction of anaerobic ponds, the welding of steel pipes on site inevitably leads to gaps between the pipes and the concrete (or casing) due to thermal expansion and contraction, which in turn causes water leakage. Once leakage occurs, it will not only waste water resources and affect the normal operation of the sewage treatment system, but may also pollute the surrounding environment and increase maintenance costs and workload.

[0004] Currently, there is a lack of effective prevention and remedial measures for water leakage between pipes and concrete (or sleeves) caused by thermal expansion and contraction. Traditional leak sealing methods are often ineffective and cannot fundamentally solve the water leakage problem caused by the gaps. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sleeve structure for sealing a concrete water tank, comprising a sleeve with a water-stopping wing ring;

[0007] The sleeve is coaxially fitted inside the perforation in the pool wall, and the water-stop wing ring is embedded in the pool wall.

[0008] A through-wall pipe is coaxially sleeved on the inner side of the sleeve, and an annular cavity is formed between the through-wall pipe and the sleeve. In the annular cavity, along the direction from the inner side to the outer side of the pool wall, a limiting ring, an asbestos cement ring, an oil hemp ring, an asbestos cement ring, and a sealant ring are arranged in sequence. The inner ring of the limiting ring is fixedly connected to the through-wall pipe, and the outer ring of the limiting ring is fixedly connected to the sleeve.

[0011] Preferably, the system also includes an anti-corrosion layer, which includes a rolled edge section and a flat section. The flat section of the anti-corrosion layer is attached to the inner side of the pool wall and has a first through hole. The through-wall pipe is sleeved inside the first through hole, and the rolled edge section of the anti-corrosion layer is sleeved on the outer side of the through-wall pipe. The end of the rolled edge section of the anti-corrosion layer near the pool wall is connected to the first through hole.

[0012] Preferably, the waterproof membrane is also included, which includes a rolled edge section and a flat section. The flat section of the waterproof membrane is attached to the surface of the flat section of the anti-corrosion layer. The flat section of the waterproof membrane is provided with a second through hole. The through-wall pipe is sleeved inside the second through hole. The rolled edge section of the waterproof membrane is sleeved outside the rolled edge section of the anti-corrosion layer. The end of the rolled edge section of the waterproof membrane near the pool wall is connected to the second through hole.

[0013] Preferably, a second stainless steel tube bundle is also included, which is sleeved on the outside of the edge section of the waterproof membrane.

[0016] Preferably, the steel collar is fixed to the pool wall by chemical bolts.

[0017] Preferably, both the waterproof membrane and the anti-corrosion layer are provided with mounting holes for the chemical bolts to pass through.

[0029] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0030] This embodiment provides a sleeve structure for sealing a concrete water tank, including a sleeve 20 with a water-stopping flange 23.

[0031] Among them, the sleeve 20 is coaxially sleeved inside the perforation of the pool wall 1, and the water-stop wing ring 23 is embedded in the pool wall 1.

[0032] For example, see Figure 1 The left side of the pool wall 1 is the inner side of the pool, and the right side is the outer side of the pool. The pool wall 1 has through holes on both sides. The sleeve 20 is a steel sleeve that is adapted to the through holes and is coaxially installed in the through holes. The water-stop wing ring 23 is pre-embedded in the pool wall 1.

[0033] A wall-penetrating pipe 11 is coaxially sleeved inside the sleeve 20. An annular cavity is formed between the wall-penetrating pipe 11 and the sleeve 20. In the annular cavity, along the direction from the inner side to the outer side of the pool wall 1, a limiting ring 24, an asbestos cement ring 21, an oil hemp ring 22, an asbestos cement ring 21, and a sealant ring 2 are arranged in sequence. The inner ring of the limiting ring 24 is fixedly connected to the wall-penetrating pipe 11, and the outer ring of the limiting ring 24 is fixedly connected to the sleeve 20.

[0034] For example, see Figure 1-2 A ring-shaped cavity with openings at both ends is formed between the through-wall pipe 11 and the sleeve 20. From left to right, the ring-shaped cavity is provided with a limiting ring 24, an asbestos cement ring 21, an oil hemp ring 22, an asbestos cement ring 21, and a sealant ring 2. The limiting ring 24, the asbestos cement ring 21, the oil hemp ring 22, and the sealant ring 2 are all coaxially adapted to the ring-shaped cavity.

[0035] The limiting ring 24 is made of stainless steel. The inner ring of the limiting ring 24 is welded to the through-wall pipe 11, and the outer ring is welded to the sleeve 20. The limiting ring 24 is used to seal the left opening of the annular cavity. The sealing paste ring 2 is made of non-toxic sealing paste and is used to seal the right opening of the annular cavity. The asbestos cement ring 21 and the hemp seed ring 22 are used to fill the remaining space inside the annular cavity. Both the asbestos cement and the hemp seed are impermeable layers, thus forming a multi-layered seal.

[0036] In summary, the sleeve structure provided in this embodiment achieves multi-layer sealing between the wall-penetrating pipe 11 and the sleeve 20 through sealant, asbestos cement, and hemp oil, effectively improving waterproof performance.

[0037] It is worth noting that the non-toxic sealant, asbestos cement, hemp oil, and sleeve 20 are installed during the pre-embedding stage of construction. The sleeve 20 forms a rigid support inside the pool wall 1, which facilitates the phased filling of asbestos cement, hemp oil, and non-toxic sealant. After the filling is completed, the limiting ring 24 can be welded.

[0038] Based on the above technical solution, in the technical solution provided in this embodiment, the gap between the sleeve 20 and the perforation of the pool wall 1 is filled with expansive cement 25.

[0039] For example, see Figure 2The gap between the left end of the sleeve 20 and the perforation in the pool wall 1 is filled with expansive cement 25, which can effectively seal the gap between the left end of the sleeve 20 and the perforation in the pool wall 1.

[0040] Furthermore, it also includes a structural adhesive ring 3, which is coaxially sleeved on the outside of the through-wall pipe 11. The structural adhesive ring 3 is simultaneously bonded and fixed to the expansive cement 25 and the through-wall pipe 11.

[0041] For example, see Figure 2 The structural adhesive ring 3 is adhered to the inner surface of the through-wall pipe 11, and the right side of the structural adhesive ring 3 is adhered to the expansive cement 25. The left side of the structural adhesive ring 3 has a small radius (R-angle). The structural adhesive ring 3 is made of epoxy resin and uses two components, providing excellent high-temperature resistance and waterproof performance.

[0042] The expansion characteristics of expansive cement 25 are used to compensate for the shrinkage stress of concrete, and stress concentration is eliminated on the outside of expansive cement 25 by structural adhesive ring 3, thereby enhancing the stability and durability of the structure.

[0043] The technical solution provided in this embodiment also includes an anti-corrosion layer 31, which includes a rolled edge section and a flat section. The flat section of the anti-corrosion layer 31 is attached to the inner side of the pool wall 1. The flat section of the anti-corrosion layer 31 is provided with a first through hole. The through-wall pipe 11 is sleeved inside the first through hole. The rolled edge section of the anti-corrosion layer 31 is sleeved outside the through-wall pipe 11. The end of the rolled edge section of the anti-corrosion layer 31 near the pool wall 1 is connected to the first through hole.

[0044] For example, see Figure 1-2 The left side of the anti-corrosion layer 31 is the rolled edge section, and the right side is the flat section. The rolled edge section can be ten centimeters long. The flat section of the anti-corrosion layer 31 is attached to the left side of the pool wall 1. The flat section of the anti-corrosion layer 31 has a first through hole running through it on both sides. The first through hole is fitted on the outside of the through-wall pipe 11. The rolled edge section of the anti-corrosion layer 31 is fitted on the outside of the through-wall pipe 11. The right end of the rolled edge section of the anti-corrosion layer 31 is aligned with the first through hole and sealed, thus forming a continuous anti-corrosion structure.

[0045] It should be noted that the structural adhesive ring 3 is located inside the rolled edge section of the anti-corrosion layer 31. The structural adhesive ring 3 can support the anti-corrosion layer 31, thereby improving the stability of the anti-corrosion layer 31.

[0046] The technical solution provided in this embodiment also includes a waterproof membrane 32, which includes a rolled edge section and a flat section. The flat section of the waterproof membrane 32 is attached to the surface of the flat section of the anti-corrosion layer 31. The flat section of the waterproof membrane 32 is provided with a second through hole. The through-wall pipe 11 is sleeved inside the second through hole. The rolled edge section of the waterproof membrane 32 is sleeved outside the rolled edge section of the anti-corrosion layer 31. The end of the rolled edge section of the waterproof membrane 32 near the pool wall 1 is connected to the second through hole.

[0047] For example, see Figure 1-2 The left side of the waterproof membrane 32 is the rolled edge section, and the right side is the flat section. The rolled edge section can be ten centimeters long. The flat section of the waterproof membrane 32 is attached to the left side of the flat section of the anti-corrosion layer 31. The flat section of the waterproof membrane 32 has a second through hole running through it on both sides. The second through hole is fitted on the outside of the through-wall pipe 11. The rolled edge section of the waterproof membrane 32 is fitted on the outside of the rolled edge section of the anti-corrosion layer 31. The right end of the rolled edge section of the waterproof membrane 32 is aligned with the second through hole and sealed, thus forming a continuous anti-corrosion structure.

[0048] The composite waterproof membrane formed by the anti-corrosion layer 31 and the waterproof membrane 32 significantly improves the waterproof performance. The rolled edge design further ensures the waterproof effect. It can adapt to changes in temperature when the through-wall pipe 11 expands and contracts with heat, thereby avoiding gaps between the pool wall 1 and the through-wall pipe 11 caused by thermal expansion and contraction, which could lead to water leakage.

[0049] Among them, the anti-corrosion layer 31 can be a three-layer cloth and five-layer oil anti-corrosion layer. The process of the three-layer cloth and five-layer oil anti-corrosion layer is as follows: first apply oil, then lay cloth alternately, for a total of five layers of oil and three layers of cloth. During installation, first ensure that the base surface is clean, dry, flat, and free of impurities such as oil, dust, and rust. Then, carry out the construction according to the design requirements, that is, first apply a layer of primer, and after the primer dries, lay a layer of fiberglass cloth, and then apply a layer of topcoat to fully impregnate the fiberglass cloth and make it firmly bonded to the base. Repeat this operation until the construction of the three-layer cloth and five-layer oil is completed.

[0050] The technical solution provided in this embodiment also includes a second stainless steel tube bundle 35, which is sleeved on the outside of the edge section of the waterproof membrane 32.

[0051] For example, see Figure 2 The second stainless steel tube bundle 35 is sleeved on the outside of the rolled edge section of the waterproof membrane 32, which can play the role of pressing and fixing the waterproof membrane 32 and the anti-corrosion layer 31.

[0052] Furthermore, it also includes a rubber waterstop ring 33 and a first stainless steel tube bundle 34. The rubber waterstop ring 33 is sleeved on the outside of the rolled edge section of the waterproof membrane 32, and the first stainless steel tube bundle 34 is sleeved on the outside of the rubber waterstop ring 33.

[0053] For example, see Figure 2 A rubber water-stop ring 33 is fitted onto the outer side of the rolled edge of the waterproof membrane 32, and is located to the right of the second stainless steel tube bundle 35. The first stainless steel tube bundle 34 can press the rubber water-stop ring 33 tightly onto the surface of the waterproof membrane 32. The rubber water-stop ring 33 deforms under pressure, thereby ensuring the contact pressure between the anti-corrosion layer 31 and the waterproof membrane 32 at the through-wall pipe 11. The second stainless steel tube bundle 35 and the first stainless steel tube bundle 34 are existing technologies, capable of pressing and fixing objects on the pipe.

[0054] The technical solution provided in this embodiment also includes a steel collar 36, which is sleeved on the outside of the through-wall pipe 11. The steel collar 36 is fixed to the pool wall 1 by bolts, and the waterproof membrane 32 and the anti-corrosion layer 31 are sandwiched between the steel collar 36 and the pool wall 1.

[0055] The steel collar 36 is fixed to the pool wall 1 by chemical bolts 37;

[0056] Both the waterproof membrane 32 and the anti-corrosion layer 31 are provided with mounting holes for the chemical bolts 37 to pass through.

[0057] For example, see Figure 3-5 The steel collar 36 is six millimeters thick, and its inner diameter is larger than the diameters of the first and second through holes to avoid interference with the anti-corrosion layer 31, waterproof membrane 32, first stainless steel tube bundle 34, and second stainless steel tube bundle 35. The steel collar 36 is installed on the left side of the pool wall 1 using chemical bolts 37 to constrain the anti-corrosion layer 31 and waterproof membrane 32 to the pool wall 1.

[0058] When installing the steel collar 36, first drill holes on the surface of the pool wall 1, inject adhesive into the holes, insert the chemical bolt 37 and cure it. At this time, the chemical bolt 37 firmly fixes the steel collar 36, the waterproof membrane 32 and the anti-corrosion layer 31 to the pool wall 1.
