Description

Technical Field

[0001] This utility model belongs to the field of wastewater collection tanks, and specifically relates to a seepage-proof structure for wastewater collection tanks. Background Technology

[0002] With the increase in industrial production and urban sewage discharge, seepage prevention in wastewater collection ponds is crucial. Traditional wastewater collection ponds often suffer from inadequate seepage prevention measures, leading to wastewater leakage and subsequent pollution of soil and groundwater. Existing seepage prevention technologies mostly use single materials or simple coatings, which are insufficient to meet the seepage prevention requirements under complex operating conditions. This wastewater collection pond's seepage prevention structure employs a multi-layered composite design, including seepage-proof plates, sealing plates, and waterproof adhesive plates, combined with threaded connections and sealing components, to achieve highly efficient wastewater barrier, providing a reliable guarantee for the safe storage and treatment of wastewater.

[0003] Existing technologies have specifically developed some seepage-proof structures for wastewater collection tanks. For example, Chinese patent publication number "CN211688317U" discloses a "seepage-proof structure for wastewater collection tanks" that enhances the sealing performance at the corners between adjacent inner sidewalls of the wastewater tank body, reducing the possibility of wastewater leakage from the corners between adjacent sidewalls of the wastewater tank body. A second sealing component is installed at the corner between the bottom wall and the inner sidewall of the wastewater tank body, thereby enhancing the sealing performance between the bottom wall and the inner sidewall of the wastewater tank body, reducing the possibility of wastewater leakage from the corners between the bottom wall and the inner sidewall of the wastewater tank body, thus enhancing the seepage-proof function of the wastewater collection tank and reducing the probability of leakage due to cracks at the corners of the tank.

[0004] Although the above structure enhances the seepage prevention of the wastewater collection tank by using sealing components at the corners, reducing the probability of leakage due to cracks at the corners of the tank, it does not provide additional seepage prevention measures around the top of the treatment tank. As a result, when the wastewater reaches the top of the treatment tank, it will leak out from the top, reducing the seepage prevention effect of the treatment tank. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a seepage-proof structure for wastewater collection ponds to solve the problems of wastewater collection ponds.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A seepage-proof structure for a wastewater collection tank includes a treatment tank. The upper perimeter of the treatment tank is integrally formed with raised plates. Rectangular plates are fixedly installed around the perimeter of the raised plates at the ends away from the treatment tank. Fixed limiting rods are fixedly installed on both sides of the ends of multiple rectangular plates away from the raised plates. Threaded posts are fixedly installed at the upper ends of multiple fixed limiting rods. Seepage-proof plates are sleeved around the outer rings of multiple threaded posts. A sealing plate is integrally formed at the bottom of the end of the seepage-proof plate away from the threaded posts. Waterproof adhesive plates are fitted and installed around the perimeter and corners of the treatment tank. A sponge board is fitted and installed at the end of the waterproof adhesive plate away from the perimeter of the treatment tank. Four side sealing plates are threadedly connected to the end of the sponge board away from the waterproof adhesive plate. Semi-circular sealing plates are threadedly connected to the four corners of the treatment tank.

[0008] As a preferred technical solution, the anti-seepage plate has multiple socket holes on all four sides of the end away from the sealing plate. The anti-seepage plate is sleeved on the outer ring of the threaded column through the multiple socket holes and abuts against the upper end of the fixed limiting rod.

[0009] As a preferred technical solution, the bonding sealing plates are all bonded to the ends of the four side sealing plates away from the sponge plate, and the ends of the multiple threaded columns away from the fixed limiting rod are all threaded with a fixing knob, which is bonded to the upper end of the anti-leakage plate.

[0010] As a preferred technical solution, a positioning strip is fixedly installed on one side of the upper end of each of the four side sealing plates, and a positioning groove is opened around the inside of the end of the anti-leakage plate that is close to the sealing plate. The positioning groove is sleeved on the outer ring of the positioning strip.

[0011] As a preferred technical solution, each of the four side sealing plates has an integrally formed isolation sealing plate on both sides, and the isolation sealing plates on both sides are attached to the two sides of the semi-circular sealing plate.

[0012] As a preferred technical solution, threaded holes are provided at the upper and lower ends and on both sides of the isolation sealing plate, sponge plate, waterproof adhesive plate and semi-circular sealing plate. Similarly, several corresponding threaded holes are provided around the inside of the treatment pool. Bolts are threadedly connected inside the threaded holes.

[0013] As a preferred technical solution, a sealing gasket is provided at the end of the multiple bolts away from the threaded hole, and the sealing gasket is located in the inner ring of the internal threaded hole opened inside the isolation sealing plate.

[0014] As a preferred technical solution, the bottom of each of the four side sealing plates is integrally formed with a sealing sticker at the end away from the sponge plate, and the side of the sealing sticker away from the side sealing plate is provided with a slope.

[0015] In summary, the present invention has the following main advantages:

[0016] First, the anti-seepage board, as the top protective layer, directly blocks wastewater from leaking upwards. Its material has good waterproof performance. Combined with the tight fit between the sealing board and the internal sealing components, it forms a solid top defense line. The waterproof adhesive board inside the treatment tank, with its tight fit with the tank wall, effectively prevents wastewater from seeping through the gaps in the tank wall.

[0017] Secondly, the anti-seepage plate is firmly fixed above the treatment tank, forming the first anti-seepage barrier. The integrated sealing plate at the bottom of the anti-seepage plate can fit tightly with the internal sealing components after installation, enhancing the overall sealing performance.

[0023] Example

[0024] refer to Figures 1-4 This embodiment of a wastewater collection tank seepage prevention structure includes a treatment tank 8. The upper circumference of the treatment tank 8 is integrally formed with raised plates 4. Rectangular plates 14 are fixedly installed around the ends of the raised plates 4 away from the treatment tank 8. Fixed limiting rods 17 are fixedly installed on both sides of the ends of the rectangular plates 14 away from the raised plates 4. Threaded posts 16 are fixedly installed at the upper ends of the fixed limiting rods 17. Seepage prevention plates 3 are sleeved around the outer rings of the threaded posts 16. Sealing plates 5 are integrally formed at the bottom of the ends of the seepage prevention plates 3 away from the threaded posts 16. Waterproof adhesive plates 12 are fitted and installed around the interior circumference and corners of the treatment tank 8. A sponge plate 13 is fitted and installed around the end of the waterproof adhesive plate 12 away from the interior circumference of the treatment tank 8. Four side sealing plates 6 are threadedly connected to the end of the sponge plate 13 away from the waterproof adhesive plate 12. Semi-circular sealing plates 1 are threadedly connected to the four corners inside the treatment tank 8.

[0025] refer to Figures 2 to 4 The anti-seepage plate 3 has multiple socket holes 15 around its inner perimeter at the end furthest from the sealing plate 5. The anti-seepage plate 3 is fitted onto the outer ring of the threaded post 16 through the multiple socket holes 15, abutting against the upper end of the fixing limit rod 17. The sealing plate 5 is attached to the ends of the four side sealing plates 6 furthest from the sponge plate 13. The ends of the multiple threaded posts 16 furthest from the fixing limit rod 17 are threaded with fixing knobs 2. The fixing knobs 2 are attached to the upper end of the anti-seepage plate 3. A fixed knob is fixedly installed on one side of the upper end of each of the four side sealing plates 6. Positioning grooves 20 are provided around the inner perimeter of the positioning strip 21 and the anti-seepage plate 3, which are close to the sealing plate 5. The positioning grooves 20 are fitted onto the outer ring of the positioning strip 21. The anti-seepage plate 3 serves as the top protective layer, directly blocking wastewater from leaking upwards. Its material has good waterproof performance. Together with the tight fit between the sealing plate 5 and the internal sealing components, it forms a solid top defense line. The waterproof adhesive plate 12 inside the treatment tank 8 effectively prevents wastewater from seeping through the gaps in the tank wall due to its tight fit with the tank wall.

[0026] refer to Figures 2 to 3 Each of the four side sealing plates 6 has an integrally formed isolation sealing plate 18 on both sides. The isolation sealing plates 18 on both sides are attached to the sides of the semi-circular sealing plate 1. The integrally formed isolation sealing plates 18 on both sides of the side sealing plate 6 are tightly attached to the semi-circular sealing plates 1 at the four corners inside the treatment pool 8, which are threaded together to strengthen the sealing of the corners inside the treatment pool 8, which are prone to leakage. The isolation sealing plate 18, the sponge plate 13, the waterproof adhesive plate 12, and the upper and lower ends and the interior of both sides of the semi-circular sealing plate 1 are all provided with threaded holes 9. Several corresponding threaded holes 9 are also provided around the inside of the treatment pool 8. Bolts 7 are threadedly connected inside the threaded holes 9. A sealing gasket 11 is provided at the end of the bolts 7 away from the threaded holes 9. The sealing gasket 11 is located in the inner ring of the internal threaded hole 9 opened inside the isolation sealing plate 18. Each sealing plate is connected to the treatment pool 8 through the threaded holes 9 and the bolts 7 are used to further improve the sealing performance.

[0027] refer to Figures 1 to 2 Each of the four side sealing plates 6 has an integrally formed sealing sticker 10 at the bottom end away from the sponge plate 13. The sealing sticker 10 has a slope 19 on the side away from the side sealing plate 6. The slope 19 design of the sealing sticker 10 guides the wastewater to flow quickly to the bottom of the treatment tank 8, reduces the erosion of the bottom of the sealing structure by the wastewater, and extends the service life of the anti-seepage structure.

[0028] Operating principle and advantages: When installing the seepage prevention structure of the wastewater collection tank, the treatment tank 8 serves as the basic carrier. Firstly, the integrally formed raised plate 4 on its upper perimeter provides the installation foundation for subsequent components. The rectangular plate 14 fixed at the end of the raised plate 4 away from the treatment tank 8 further expands the installation space. A stable external support frame is constructed through the fixed limiting rods 17 on both sides and the threaded post 16 at the top. The seepage prevention plate 3, through the socket holes 15 on its perimeter, is precisely fitted onto the outer ring of the threaded post 16 and abuts against the upper end of the fixed limiting rod 17, achieving initial positioning. Subsequently, the fixing knob 2 is threaded onto the top of the threaded post 16, ensuring a tight fit against the upper end of the seepage prevention plate 3. Tightening the fixing knob 2 generates downward pressure, firmly securing the seepage prevention plate 3. Fixed above the treatment tank 8, forming the first seepage barrier, the bottom of the seepage barrier plate 3 has an integrally formed sealing plate 5 that can fit tightly with the internal sealing components after installation, enhancing the overall sealing performance. The installation of the seepage barrier components inside the treatment tank 8 is equally crucial. First, the waterproof adhesive plate 12 is tightly attached to the inside of the treatment tank 8 around the perimeter and corners, utilizing its adhesive properties to initially block wastewater seepage. Next, a sponge plate 13 is attached to the outside of the waterproof adhesive plate 12. The sponge plate 13 has good water absorption and buffering properties, which can absorb a small amount of wastewater that may leak, while also mitigating the impact of wastewater on the subsequent sealing plates. Four side sealing plates 6 are fixed to the outside of the sponge plate 13 by threaded connection. The positioning strip 21 at the upper end of the side sealing plate 6 cooperates with the positioning groove 20 of the seepage barrier plate 3. To ensure accurate installation of the side sealing plate 6 and prevent misalignment from affecting the sealing effect, the integrally formed isolation sealing plates 18 on both sides of the side sealing plate 6 are tightly fitted with the semi-circular sealing plates 1 threaded at the four corners inside the treatment tank 8. Together, they reinforce the sealing of the high-leakage areas at the corners inside the treatment tank 8. Each sealing plate is connected to the treatment tank 8 by bolts 7 through threaded holes 9. To further improve the sealing performance, a sealing gasket 11 is placed at the end of the bolt 7 away from the threaded hole 9 and embedded in the inner ring of the internal threaded hole 9 inside the isolation sealing plate 18 to ensure no leakage gaps at the connection. The sealing sticker 10 at the bottom of the side sealing plate 6 has a slope design 19, which guides the wastewater to the center of the treatment tank 8 after installation, preventing wastewater from accumulating at the bottom of the sealing plate. To reduce the risk of leakage, after wastewater is injected into treatment tank 8, the components of the anti-seepage structure work together. The anti-seepage plate 3, as the top protective layer, directly blocks wastewater from leaking upwards. Its material has good waterproof performance. Together with the tight fit between the sealing plate 5 and the internal sealing components, it forms a solid top defense line. The waterproof adhesive plate 12 inside treatment tank 8, with its tight fit with the tank wall, effectively prevents wastewater from seeping through the gaps in the tank wall. The sponge plate 13 absorbs the small amount of wastewater that may seep through the waterproof adhesive plate 12, playing a buffering and secondary interception role. The sealing frame composed of four side sealing plates 6 and semi-circular sealing plates 1 provides all-round sealing of wastewater from all sides and corners. The side sealing plates 6 and the anti-seepage plate 3 are connected by positioning strips 21 and positioning grooves 20.The fastening effect of bolts 7 ensures a stable and seamless sealing structure. The fitting design of the isolation sealing plate 18 and the semi-circular sealing plate 1 further enhances the sealing effect at the corners. Since stress is concentrated at the corners of the treatment tank 8, cracks can easily appear, leading to leakage. The combination of the isolation sealing plate 18 and the semi-circular sealing plate 1 effectively disperses stress. Simultaneously, the use of bolts 7 and sealing gaskets 11 eliminates the possibility of wastewater leakage from the corners. The slope 19 design of the sealing pad 10 guides wastewater to flow quickly to the bottom of the treatment tank 8, reducing erosion of the bottom of the sealing structure and extending the service life of the anti-seepage structure. During long-term use, if some sealing components are damaged or aged, the corresponding anti-seepage plate 3, side sealing plate 6, and other components can be replaced and repaired by disassembling the fixing knob 2 and bolts 7, without requiring large-scale modification of the entire anti-seepage structure; the operation is simple and quick.
