Description

Technical Field

[0001] This utility model relates to the field of sealing structures, and in particular to a sealing structure for preventing water seepage in sedimentation tanks. Background Technology

[0002] Sedimentation tanks are a type of water treatment equipment widely used in many fields. They are mainly used to achieve solid-liquid separation, allowing suspended solid particles in the water to settle to the bottom of the tank through gravity sedimentation, thereby purifying the water.

[0003] Most existing sedimentation tanks are one-piece, enclosed spaces constructed with cement. However, these one-piece structures cannot be disassembled and reused, resulting in low flexibility in use. Furthermore, when water seepage occurs in cement sedimentation tanks, the equipment needs to be repainted, leading to a waste of financial and material resources.

[0004] Therefore, since most of the existing sedimentation tanks are integral, sealed spaces constructed with cement, which have low flexibility in use, a water-proof sealing structure for sedimentation tanks can be designed to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing sedimentation tanks, which are mostly enclosed spaces made of cement, but cannot be disassembled and used, and require repainting when water seepage occurs, resulting in a waste of financial and material resources, as well as low flexibility in use.

[0006] The technical solution of this utility model is as follows: a sealing structure for preventing water seepage in a sedimentation tank, comprising an outer tank body, absorbent cotton, fixed columns, an inner waterproof layer, a slotted plate, a frame, connecting columns, connecting straps, a waterproof membrane, a pressure ring, a top cover, and a surrounding plate. Absorbent cotton is provided on the inner side of the outer tank body, and fixed columns are provided between adjacent groups of absorbent cotton. An inner waterproof layer is provided on the inner side of the absorbent cotton, and a slotted plate is provided at the upper end of the inner waterproof layer. A frame is provided at the upper end of the slotted plate, and a connecting column is provided at the upper end of the frame. The upper suspension is connected by a connecting strap, with a waterproof membrane between the connecting straps. A pressure ring is installed on the outside of the connecting column, and a top cover is installed at the upper end of the pressure ring. A surrounding plate is installed at the upper end of the top cover. The frame is connected to the outer pool body and the gap formed by the inner waterproof layer by setting a slot plate for insertion connection. The connecting strap is suspended between the connecting column and the pressure ring for quick assembly and disassembly, which is convenient to use. At the same time, water-absorbing cotton, inner waterproof layer and waterproof membrane are set for multiple waterproofing work. The top cover and surrounding plate are pressed together to achieve a seal.

[0007] Preferably, the wedge-shaped connection allows for easy and flexible use.

[0008] Preferably, the outer pool is set as a hollow rectangle, the inner waterproof layer is set as a rectangular frame, and absorbent cotton is provided on each side of the gap formed by the outer pool and the inner waterproof layer, and an outer pool is provided between the absorbent cotton on adjacent sides.

[0009] Preferably, water-condensing particles are placed in the gap between the outer pool body and the inner waterproof layer, and the water-condensing particles fill the area around the absorbent cotton.

[0010] Preferably, a slotted plate is inserted into the upper end of the gap formed by the outer pool body and the inner waterproof layer. The slotted plate, the frame and the four connecting columns are set as a whole, and the connecting columns are set at the four corners of the upper end of the frame.

[0011] Preferably, the connecting strip is suspended on the connecting post, and the pressure ring is inserted into the outside of the connecting post and is located at the upper end of the connecting strip.

[0012] Preferably, a waterproof membrane is provided between the four connecting strips, and the waterproof membrane is made of a soft material.

[0013] Preferably, the pressure ring, top cover, and surrounding plate are configured as a single unit, and the connecting column, connecting strip, and pressure ring are configured to correspond one-to-one.

[0014] The beneficial effects of this utility model are:

[0015] 1. An external tank provides an outer layer of protection, while an inner waterproof layer provides internal waterproofing. Fixed columns secure absorbent cotton within the gap formed by the external tank and the inner waterproof layer. Water-condensing granules surround the absorbent cotton, providing secondary waterproofing. A slotted plate secures the connecting frame, inserting into the gap for easy assembly and disassembly. The absorbent cotton and condensing granules can be replaced after water absorption. Connecting columns, fixed to the frame, can be fitted with connecting straps that connect to the waterproof membrane, providing further waterproofing. A pressure ring, top cover, and surrounding plate are placed at the top for tightening, ensuring a sealed environment. This design overcomes the shortcomings of existing sedimentation tanks, which are mostly monolithic, sealed spaces constructed of cement. However, monolithic designs cannot be disassembled, and when seepage occurs, the system requires repainting, resulting in wasted resources. Furthermore, the system lacks flexibility in use.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Among the currently discovered feasible technologies, the following is a description of a sealing structure for preventing water seepage in sedimentation tanks:

[0023] I. Structural Composition

[0024] Pool foundation sealing layer:

[0025] At the bottom foundation of the sedimentation tank, a layer of waterproof concrete with good sealing properties is first laid. This concrete can be made with a special formula that includes a waterproofing agent, and its proportions need to be determined according to the specific usage environment and requirements of the sedimentation tank. For example, for sedimentation tanks that are in a high-humidity environment for a long time or that store corrosive liquids, waterproof concrete with a higher impermeability grade, such as P8 or P10, can be selected (the impermeability grade indicates the concrete's ability to resist the penetration of pressurized water; the higher the number, the stronger the impermeability).

[0026] During concrete pouring, it is essential to ensure thorough compaction to prevent defects such as honeycomb or pitted surfaces that could lead to water seepage. Simultaneously, a finishing process should be performed before the concrete reaches its final set to ensure a smooth surface and reduce gaps that could allow moisture to penetrate.

[0027] Waterproof membrane layer for pool walls:

[0028] Waterproof membrane is applied to the outer wall of the sedimentation tank, starting from the bottom foundation and working upwards. Commonly used waterproof membranes include SBS modified bitumen waterproof membrane and polymer waterproof membrane.

[0029] SBS modified bitumen waterproof membrane has good weather resistance, water resistance, and puncture resistance, making it suitable for most sedimentation tank environments. When applying the membrane, the tank wall surface should first be cleaned and leveled to ensure it is free of dust, debris, and protrusions. Then, the waterproof membrane should be firmly adhered to the tank wall using either a hot-melt or cold-bonding method. The overlap width between membrane sections should meet relevant standards, generally not less than 100mm, to ensure a good seal.

[0030] Polymer waterproof membranes have higher tensile strength and tear resistance, making them more suitable for sedimentation tank walls that may be subjected to external pressure or deformation. The application method varies depending on the type of polymer membrane; some are self-adhesive, while others require special adhesive. However, it is equally important to ensure a tight bond and proper overlap.

[0031] Pool wall sealant layer:

[0032] After the waterproof membrane is applied to the pool walls, apply sealant to the seams of the membrane and at the connections between the pool walls and other structural components (such as inlet / outlet pipes, overflow pipes, etc.). Commonly used sealants include silicone sealant and polyurethane sealant.

[0033] Silicone sealants offer excellent weather resistance, water resistance, and sealing performance, making them suitable for sedimentation tanks exposed to outdoor environments for extended periods. Polyurethane sealants, on the other hand, excel in chemical corrosion resistance, making them more suitable for sedimentation tanks that may come into contact with chemical agents.

[0034] When applying sealant, ensure it is applied evenly and fully, completely filling any gaps at the joints or connections. The sealant thickness should also meet certain requirements, generally recommended to be around 3-5mm, to form an effective sealing barrier.

[0035] Pool top sealing cover:

[0036] For sedimentation tanks with a roof, the roof should be covered with a sealing cover. The sealing cover can be made of materials such as steel plate or fiberglass.

[0037] Steel plate sealing covers are strong and can withstand certain external loads, but they require anti-corrosion treatment, such as galvanizing and painting, to prevent rust and water leakage. Fiberglass sealing covers, on the other hand, are lightweight, corrosion-resistant, and easy to mold, allowing for custom manufacturing to fit the shape of the sedimentation tank roof.

[0038] At the connection between the sealing cover plate on the top of the tank and the tank wall, sealant or rubber sealing strips should also be used to seal the connection to ensure that rainwater and other substances do not seep into the sedimentation tank from the connection.

[0039] II. Working Principle

[0040] The coordinated effect of multiple lines of defense:

[0041] This sealing structure works in concert through multiple sealing lines, including the base sealing layer of the pool body, the waterproof membrane layer of the pool wall, the sealant layer of the pool wall, and the sealing cover plate on the top of the pool, to prevent water from seeping into the sedimentation tank from different parts and levels.

[0042] The base sealing layer of the sedimentation tank is mainly designed to prevent groundwater seepage at the bottom of the sedimentation tank and downward leakage of liquid inside the tank. The dense structure of waterproof concrete blocks the passage of water.

[0043] The waterproof membrane layer and the sealant layer on the pool wall are designed to prevent water seepage from the sides of the pool wall. The waterproof membrane provides a large-area waterproof barrier, while the sealant reinforces and seals weak points at the joints of the membrane and at connections with other components.

[0044] The sealing treatment of the top cover plate and its connection with the pool wall is to prevent rainwater and water vapor in the atmosphere from seeping into the sedimentation tank from the top.

[0045] Block the seepage channels:

[0046] Each sealing barrier blocks potential seepage channels through filling, covering, and pasting. For example, the tiny pores in the waterproof concrete are filled with waterproofing agent, making it difficult for water to seep in; the waterproof membrane is tightly adhered to the pool wall, blocking the path of water penetration along the wall; sealant fills the gaps at joints and connections, eliminating the possibility of water seeping in from these weak points; and the sealing cover and its sealing treatment on the pool top also prevent rainwater from entering the sedimentation tank from the connection between the pool top and the pool wall.

[0047] III. Advantages

[0048] Excellent waterproofing effect:

[0049] Thanks to the use of multiple sealing lines and the special design for different parts and possible seepage situations, this sealing structure can effectively prevent liquid from seeping out of the sedimentation tank and water from seeping in from the outside, ensuring the normal use of the sedimentation tank.

[0050] During long-term operation, even when encountering severe weather conditions (such as rainstorms, floods, etc.) or subjected to a certain degree of external force (such as the compression of the soil around the pool wall), it can maintain good seepage prevention performance.

[0051] Highly adaptable:

[0052] This sealing structure can be customized for different types and sizes of sedimentation tanks. For example, for large sedimentation tanks, the thickness of the waterproof membrane and the amount of sealant can be increased to accommodate the larger tank wall area and the potentially greater seepage pressure. For small sedimentation tanks, the materials and processes of each sealing line can be configured according to actual needs to reduce costs while ensuring the effectiveness of preventing seepage.

[0053] At the same time, it can adapt to different usage environments, such as industrial wastewater treatment sedimentation tanks, domestic sewage treatment sedimentation tanks, rainwater collection sedimentation tanks, etc. No matter what environment, as long as the appropriate materials are selected according to the specific situation (such as chemically resistant sealing materials for industrial wastewater treatment sedimentation tanks), good water-proof function can be achieved.

[0054] Extend the service life of sedimentation tanks:

[0055] Effectively preventing water seepage can avoid damage to the pool structure caused by seepage, such as concrete erosion and steel reinforcement corrosion.

[0056] When the liquid in the sedimentation tank does not leak and external water does not seep in, the tank structure can remain relatively intact, thereby extending the service life of the sedimentation tank, reducing the frequency of maintenance and replacement, and lowering operating costs.

[0057] IV. Application Cases

[0058] Sedimentation tanks in industrial wastewater treatment plants:

[0059] This seepage-proof sealing structure was used in the primary and secondary sedimentation tanks of a large industrial wastewater treatment plant. Because industrial wastewater typically contains large amounts of chemicals, there is a significant risk of corrosion and seepage into the tank structures.

[0060] By selecting chemically resistant waterproof membranes (such as polymer waterproof membranes) and sealants (such as polyurethane sealants), and strictly following the design and construction process of the above-mentioned sealing structure, a good seepage prevention effect was successfully achieved, ensuring the normal operation of the industrial wastewater treatment process, and also extending the service life of the sedimentation tank.

[0061] Sedimentation tanks in domestic sewage treatment plants:

[0062] This sealing structure has also been used in sedimentation tank projects at some domestic wastewater treatment plants. Considering the characteristics of domestic wastewater, conventional SBS modified bitumen waterproof membrane and silicone sealant were used, while P8 waterproof concrete with a seepage resistance rating was used for the tank foundation.

[0063] After actual operation testing, the sealing structure effectively prevents leakage of domestic sewage and infiltration of external rainwater, providing a reliable pool body guarantee for domestic sewage treatment.

[0064] Rainwater collection and sedimentation tank:

[0065] This same seepage-proof sealing structure is also used in some sedimentation tanks used for rainwater harvesting and utilization. Considering that rainwater harvesting sedimentation tanks may be affected by factors such as different seasons and different rainfall amounts, fiberglass is used for the sealing cover of the tank top to reduce weight and improve weather resistance.

[0066] By rationally configuring the materials and processes of each sealing line, the rainwater collection sedimentation tank achieves excellent seepage prevention, ensuring the smooth progress of the rainwater collection and utilization project.

[0067] This type of sealing structure for preventing seepage in sedimentation tanks, through scientific and reasonable design and strict construction process, can effectively solve the seepage problem in sedimentation tanks and has broad application prospects in various sedimentation tank projects.
