Description

Technical Field

[0001] This application relates to the technical field of composite connection structure buildings, and more particularly to a connection structure between a storage tank and a reinforced concrete foundation. Background Technology

[0002] In modern environmental engineering and municipal construction, wastewater treatment plants, as a crucial component of urban infrastructure, directly impact urban sustainable development and residents' quality of life through their design and construction quality. Steel storage tanks, a key facility in wastewater treatment plants, are primarily used to store wastewater during treatment or treated reclaimed water. The design and construction of these tanks require comprehensive consideration of various factors, including but not limited to structural strength, corrosion resistance, sealing performance, seismic resistance, and economic costs. With increasingly stringent environmental regulations and technological advancements, steel storage tanks in wastewater treatment plants must not only meet the functional requirements of efficient wastewater treatment but also ensure long-term operational safety and reliability. Therefore, engineering technologies in this field are constantly evolving to adapt to higher standards and more complex operating conditions.

[0003] In recent years, an innovative design concept—steel storage tanks without traditional steel bottom plates—has emerged in the construction of steel storage tanks for wastewater treatment plants, demonstrating significant advantages in several aspects. This design effectively reduces material costs, particularly the need for expensive steel, by optimizing the tank's bottom structure, thus achieving cost savings in the initial stages of project construction. From a construction perspective, storage tanks without steel bottom plates simplify the foundation construction process, shorten the construction cycle, and improve the flexibility of project schedule management. Due to the reduction in on-site welding work, these tanks are safer and more reliable during installation, reducing construction risks. In summary, these characteristics make steel storage tanks without steel bottom plates an ideal choice for many new or renovation projects.

[0004] While the aforementioned steel storage tanks without steel bottom plates offer numerous advantages, practical applications have revealed some technical shortcomings that need to be addressed. Leakage is particularly common at the connection between the storage tank and the reinforced concrete foundation. This problem not only leads to sewage leakage and environmental pollution but can also erode the foundation structure, threatening the overall stability and safety of the storage tank. Traditional repair methods often fail to completely resolve the issue, either due to the complexity of the construction process or the prohibitive cost. This indicates that current technologies are insufficient for waterproofing and seepage prevention at such joints, failing to fully meet the comprehensive demands of modern engineering construction for efficiency, economy, and reliability. Therefore, exploring new solutions to improve the sealing performance of the bottom connection area of ​​the storage tank has become crucial for enhancing the overall performance of sewage treatment plant facilities.

[0041] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0042] Reference Figures 1 to 11 As shown, an embodiment of this application proposes a connection structure between a storage tank and a reinforced concrete foundation. This connection structure may include: a reinforced concrete layer 1 having a first surface 1a, on which an annular mounting groove 11 is provided; an embedded part 2, which is embedded in the reinforced concrete layer 1 at a target position within the mounting groove 11; and a storage tank 3 connected to each embedded part 2, thereby dividing the mounting groove 11 into a first groove 11a and a second groove 11b via the storage tank 3. The first groove 11a is located within the storage tank 3. On the side, the second tank 11b is located outside the storage tank 3; the concrete composite layer 4 includes several layers of concrete stacked together, the concrete composite layer 4 is connected to the tank walls of the first tank 11a and the second tank 11b and the wall panel of the storage tank 3; and the water-stopping functional layer 5 is disposed in the concrete composite layer 4 inside the first tank 11a, the water-stopping functional layer 5 is arranged circumferentially along the first tank 11a to form a closed loop structure, the water-stopping functional layer 5 can increase its own volume after encountering water, and is used to fill the gap between the concrete layers in the concrete composite layer 4.

[0043] Specifically, in the technical solution adopted in this application, an installation groove 11 is provided on the first surface 1a of the reinforced concrete layer 1. The first surface 1a is the side surface of the reinforced concrete layer 1 facing away from the ground, and the installation groove 11 is set as a ring structure. In this embodiment, the installation groove 11 can be a square ring structure, a circular ring structure, or a ring structure of other shapes. In actual situations, it can be determined by referring to the bottom shape of the storage tank 3. In this application, a steel frame structure is formed by binding steel bars. The target position is determined on the steel frame structure, and the embedded parts 2 are installed at the corresponding target positions. In order to connect with the wall panel of the storage tank 3, multiple embedded parts 2 can be used to form a ring array corresponding to the target positions of the ring installation groove 11. A foundation template is erected on the steel frame structure to form the basic shape of the reinforced concrete layer 1. Finally, concrete is poured to form the reinforced concrete layer 1. Each target position is located near the middle of the bottom of the installation groove 11. Each embedded part 2 is arranged circumferentially around the ring structure of the installation groove 11 so that each embedded part 2 forms a ring array in the installation groove 11. In this application, the storage tank 3 is a steel storage tank without a bottom plate, such as an anaerobic tank, water storage tank, or sewage treatment tank without a steel bottom plate. The end of the wall panel near the bottom of the storage tank 3 can be fixedly connected to the embedded part 2 by welding. Since the target position is close to the middle of the installation groove 11, the installation groove 11 can be divided into a first groove 11a and a second groove 11b by the wall panel of the storage tank 3. To facilitate the distinction between the first groove 11a and the second groove 11b, the groove located inside the storage tank 3 can be defined as the first groove 11a, and the groove located outside the storage tank 3 can be defined as the second groove 11b. The installation groove 11 is also provided with a concrete composite layer 4, which is used to attach to the inner and outer sides of the wall panel of the storage tank 3. Specifically, the concrete composite layer 4 is fixedly connected to the bottom and wall of the first groove 11a and the second groove 11b, as well as the inner and outer sides of the wall panel of the storage tank 3. The concrete composite layer 4 in this application is composed of multiple concrete layers. During the construction process, concrete can be poured in the installation groove 11 in batches to form the concrete composite layer 4. Specifically, the operation method can be to pour concrete into the installation groove 11 once, and after the concrete has completely solidified, pour concrete a second time, and so on, so as to form the concrete composite layer 4. The key technical feature of this application is that a water-stopping functional layer 5 is provided in the concrete composite layer. The water-stopping functional layer 5 is located in the concrete composite layer 4 of the first tank 11a. The water-stopping functional layer 5 has water-swelling properties. In one embodiment, a water-swelling water-stopping strip adapted to the bottom structure of the first tank 11a can be selected. The water-stopping functional layer 5 is a closed-loop structure and is laid along the circumference of the first tank 11a. The water-swelling water-stopping strip can be made of rubber, such as natural rubber or neoprene rubber, thereby improving the anti-leakage performance of the connection structure between the storage tank and the reinforced concrete foundation.The construction process can be as follows: simultaneously pour concrete into the first trench 11a and the second trench 11b, wait for the concrete to solidify to form a concrete layer, lay a water-stopping functional layer 5 on the solidified concrete layer in the first trench 11a, and after the water-stopping functional layer 5 is laid, pour concrete into the first trench 11a and the second trench 11b again simultaneously.

[0044] Natural rubber possesses excellent elasticity, abrasion resistance, and tensile strength. Its flexible molecular chains allow it to swell to some extent upon contact with water. This swelling is due to the numerous spaces between the rubber molecules that can accommodate water molecules; when water molecules enter these spaces, the rubber expands in volume. Furthermore, the elasticity of natural rubber allows it to adapt well to structural deformation during waterproofing, ensuring a tight seal at seams and effectively preventing water leakage.

[0045] Chloroprene rubber: In addition to its good elasticity, this rubber also possesses excellent weather resistance, aging resistance, and chemical corrosion resistance. When used in water-swellable waterproofing strips, it maintains good waterproofing performance even under prolonged exposure to humid environments or chemical corrosion. The presence of chlorine atoms in its molecular structure gives chloroprene rubber a certain degree of resistance to acids, alkalis, and other chemicals. Its water-swelling mechanism primarily involves the interaction of its internal hydrophilic groups with water molecules, thereby increasing the rubber's volume.

[0046] Specifically, in one embodiment of the technical solution adopted in this application, an uneven structure 12 can be formed on the surface of the bottom and wall of the installation groove 11 to enhance the adhesion between the reinforced concrete layer 1 and the concrete composite layer 4. This uneven structure 12 can be roughened manually or mechanically, with the roughening depth controlled between 5 and 10 millimeters. The roughened surface of the installation groove 11 is roughened to effectively enhance the adhesion between the new and old concrete. Subsequently, pressurized clean water can be used to rinse the concrete foundation and the interior of the installation groove 11. After drying, a layer of cement slurry or a special concrete interface agent can be evenly applied to create good bonding conditions for subsequent construction.

[0047] Furthermore, refer to Figure 6 and Figure 8 As shown, in some embodiments, the concrete composite layer includes: a first concrete layer 41 disposed in the first tank 11a, the first concrete layer 41 being connected to the tank wall of the first tank 11a and the wall panel of the storage tank 3; and a second concrete layer 42 disposed on the side of the first concrete layer 41 away from the bottom of the first tank 11a, the second concrete layer 42 being connected to the tank wall of the first tank 11a and the wall panel of the storage tank 3.

[0048] The water-stopping functional layer 5 is located between the first concrete layer 41 and the second concrete layer 42.

[0049] Specifically, in some embodiments of the technical solution adopted in this application, the first concrete layer 41 and the second concrete layer 42 can be formed by pouring concrete in batches. For example, concrete is first poured into the first tank 11a to form the first concrete layer 41, and after the first concrete layer 41 has solidified and hardened, concrete is poured into the first tank 11a again to form the second concrete layer 42. The first concrete layer 41 is fixedly connected to the bottom and walls of the first tank 11a and the inner surface of the wall panel of the storage tank 3; the second concrete layer 42 is fixedly connected to the walls of the first tank 11a and the wall panel of the storage tank 3. In this embodiment, the water-stopping functional layer 5 is disposed between the first concrete layer 41 and the second concrete layer 42. When it is necessary to implement the connection structure proposed in this embodiment, the construction process that can be adopted is as follows: after the first concrete layer 41 has solidified and hardened, the water-stopping functional layer 5 is laid along the circumference of the first trench 11a. After the water-stopping functional layer 5 is laid, the second concrete layer 42 is poured to lay the water-stopping functional layer 5 between the first concrete layer 41 and the second concrete layer 42.

[0050] Furthermore, refer to Figure 6 and Figure 8 As shown, in some embodiments, the concrete composite layer further includes: a third concrete layer 43 disposed in the second tank 11b, the third concrete layer 43 being connected to the tank wall of the second tank 11b and the wall panel of the storage tank 3; and a fourth concrete layer 44 disposed on the side of the third concrete layer 43 away from the bottom of the second tank 11b, the fourth concrete layer 44 being connected to the tank wall of the second tank 11b, the third concrete layer 43 and the wall panel of the storage tank 3.

[0051] Specifically, in the technical solution adopted in this application, in a further embodiment, the third concrete layer 43 and the fourth concrete layer 44 can be formed by pouring concrete in batches. For example, concrete is first poured into the second tank 11b to form the third concrete layer 43, and after the third concrete layer 43 has solidified and hardened, concrete is poured into the second tank 11b again to form the fourth concrete layer 44. The third concrete layer 43 is fixedly connected to the bottom and walls of the second tank 11b and the wall panel of the storage tank 3, while the fourth concrete layer 44 is fixedly connected to the first concrete layer 41, the walls of the second tank 11b, and the outer surface of the wall panel of the storage tank 3. Thus, the concrete composite layer 4 composed of four concrete layers can be set in pairs in the first tank 11a and the second tank 11b, and located on both sides of the wall panel of the storage tank 3 to help strengthen the connection structure between the wall panel of the storage tank 3 and the embedded part 2.

[0052] Furthermore, refer to Figure 8As shown, in some embodiments, it further includes: a first functional layer 6, which is disposed between the first concrete layer 41 and the water-stopping functional layer 5. The first functional layer 6 is used to fill the gap between the first concrete layer 41 and the water-stopping functional layer 5, and the first functional layer 6 has a waterproof sealing function.

[0053] Specifically, in some embodiments of the technical solution adopted in this application, the first functional layer 6 can be a waterproof sealant applied to the first concrete layer 41, such as polyurethane waterproof sealant, silicone waterproof sealant or acrylic waterproof sealant, so that when the water-stopping functional layer 5 is laid on the first concrete layer 41, it can fill the gap between the first concrete layer 41 and the water-stopping functional layer 5, and the waterproof sealant has the property of adhering to objects, so the water-stopping functional layer 5 can be fixed on the first concrete layer 41 by the adhesive properties of the first functional layer 6.

[0054] Furthermore, refer to Figure 5 As shown, in some embodiments, it further includes a second functional layer 7, which is disposed on the surfaces of the first surface 1a and the third concrete layer 43 and the fourth concrete layer 44 away from each embedded part 2, and the second functional layer 7 has waterproof sealing and anti-corrosion properties.

[0055] Specifically, in some embodiments of the technical solutions adopted in this application, the second functional layer 7 can be a waterproof and anti-corrosion coating applied to the reinforced concrete layer 1, the third concrete layer 43, and the fourth concrete layer 44. The waterproof sealant is, for example, polyurethane waterproof sealant, silicone waterproof sealant, or acrylic waterproof sealant, and the anti-corrosion adhesive is, for example, epoxy resin anti-corrosion adhesive or polyurea anti-corrosion adhesive. This can enhance the waterproof and anti-corrosion capabilities of the entire connection structure between the storage tank and the reinforced concrete foundation, improve the stability and reliability of the connection structure between the steel storage tank and the reinforced concrete foundation, extend the service life of the storage tank 3, and reduce construction and subsequent maintenance costs.

[0056] Before laying the second functional layer 7 in the construction process of this connection structure, the airtightness and stability of the connection structure between the storage tank and the reinforced concrete foundation can be tested. Specifically, the airtightness test involves checking the sealing performance of the connection between the bottom of the storage tank 3 and the reinforced concrete layer 1 through a water injection test. Water is injected into the storage tank 3 to two-thirds of the design maximum water level and maintained for a certain period, such as 24 to 48 hours. The wall panels, tank bottom, and connection points are observed for any leakage, and the deformation of the storage tank is also checked. If leakage is found, the cause is analyzed and corresponding measures are taken. The cause is promptly marked and analyzed, and repairs are carried out until the water filling test is passed. The stability test involves setting up observation points around the storage tank 3 and measuring the horizontal displacement and settlement of the storage tank 3 under different conditions of no-load and full-load. This determines whether the connection meets the normal use requirements of the storage tank 3. The horizontal displacement and settlement should be controlled within the design allowable range, for example, the horizontal displacement should not exceed 10 mm, and the settlement should not exceed 50 mm.

[0057] Furthermore, refer to Figure 9 As shown, in some embodiments, the embedded part 2 includes: a base 21, which is embedded in the reinforced concrete layer 1; and a connecting plate 22, which is fixedly connected to the base 21, with the side surface of the connecting plate 22 facing away from the base 21 exposed at the bottom of the mounting groove 11.

[0058] Specifically, in one embodiment of the technical solution adopted in this application, since the base 21 is used to be embedded in the reinforced concrete layer 1, the base 21 can be a plate-shaped steel member with a bent structure to be supported on the steel frame in the reinforced concrete layer 1. Specifically, when binding the steel frame of the reinforced concrete layer 1, the target position of each embedded part 2 on the steel frame is fixed, which is the target position near the middle of the bottom of the installation groove 11. After the foundation template is erected, concrete is poured to embed the base 21 in the reinforced concrete layer 1 and place it at the target position. The connecting plate 22 can be fixedly connected to the base 21 by welding. One side surface of the connecting plate 22 is exposed at the bottom of the installation groove 11, which is the side surface of the connecting plate 22 away from the base 21, and is used to connect the wall panel of the storage tank 3. In this embodiment, one side surface of the connecting plate 22 is set as a planar structure with a certain flatness, so as to increase the connection area when the wall panel of the storage tank 3 is fixedly connected to the connecting plate 22, thereby improving the stability and reliability of the connection structure.

[0059] Furthermore, refer to Figure 9As shown, in some embodiments, the base 21 includes: a main body 21a, which is configured as a bent steel member with a U-shaped cross-section and a top surface structure, the main body 21a being connected to the connecting plate 22 through the top surface structure; and two limiting parts 21b, which are formed on both ends of the main body 21a away from the connecting plate 22, the two limiting parts 21b extending to both sides of the main body 21a by bending, so as to be supported in the structure of the reinforced concrete layer 1.

[0060] Specifically, in one embodiment of the technical solution adopted in this application, the base 21 is configured as a plate-shaped steel component, the main body 21a of which is bent to form a U-shaped structure, so that the main body 21a forms a top surface structure, which can be fixedly connected to the connecting plate 22 by welding; and two limiting parts 21b are formed on both ends of the U-shaped main body 21a. The two limiting parts 21b can be bent at ninety degrees or close to ninety degrees to both sides of the main body 21a, and extend to both sides of the main body 21a, so that the two limiting parts 21b become limiting structures that can be supported in the reinforced concrete layer 1. It should be noted that the specific bending angle can be determined according to the situation and is not limited to about ninety degrees, as long as it can be supported in the foundation structure of the reinforced concrete layer 1. Therefore, bending angles of other values ​​are also within the protection scope of this application and are not limited here.

[0061] Furthermore, refer to Figure 10 and Figure 11 As shown, in some embodiments, it further includes: two connecting members 9, which are connected to both sides of the wall panel of the storage tank 3 and the connecting plate 22, for fixing the storage tank 3 to the connecting plate 22; the connecting member 9 includes: a first connecting surface 9a, which is fixedly connected to the side surface of the connecting plate 22 opposite to the base 21; and a second connecting surface 9b, which is fixedly connected to the wall panel of the storage tank 3.

[0062] The second connecting surface 9b and the first connecting surface 9a have a first included angle, and the connecting plate 22 and the wall panel of the storage tank 3 have a second included angle, the angles of the first included angle and the second included angle are equal.

[0063] Specifically, in one embodiment of the technical solution adopted in this application, the storage tank 3 can be connected to the embedded part 2 by double-sided full welding. Therefore, two steel connecting members 9 can be added to both sides of the wall panel of the storage tank 3. The connecting members 9 have a first connecting surface 9a and a second connecting surface 9b. The first connecting surface 9a is fixedly connected to the side surface of the connecting plate 22 away from the base 21 by welding, while the second connecting surface 9b is fixedly connected to the surface of the wall panel of the storage tank 3 by welding. This can increase the connection area between the wall panel of the storage tank 3 and the connecting plate 22, thereby improving the stability and reliability of the connection structure in the welding process. In this embodiment, the connecting member 9 needs to be compatible with the wall panel and connecting plate 22 of the storage tank 3. Therefore, the first connecting surface 9a and the second connecting surface 9b on the connecting member 9 form a first angle, while the wall panel and the connecting plate 22 of the storage tank 3 form a second angle. The angles of the first angle and the second angle are equal. Since the wall panel and the connecting plate of the storage tank are generally 90 degrees apart, the degree of the first angle and the second angle can be 90 degrees. That is, when the connecting member 9 is installed between the wall panel and the connecting plate 22 of the storage tank 3, the first connecting surface 9a can be tightly attached to the connecting plate 22, and the second connecting plate 22 can be tightly attached to the wall panel of the storage tank 3, so that the connecting member 9 can be fixedly connected to the wall panel and the connecting plate 22 of the storage tank 3 by full welding.

[0064] Specifically, in the technical solution adopted in this application, based on the steel material and welding requirements, a suitable welding function can be selected in this embodiment, such as manual arc welding or gas shielded welding. When using manual arc welding, the welding current is determined according to the electrode diameter. For example, for a 3.2 mm diameter electrode, the welding current is between 100 and 130 amperes. When using multi-layer, multi-pass welding, attention should be paid to cleaning each layer of weld and controlling the shape of the weld. The weld reinforcement can be controlled between 0 and 3 mm. After welding, the weld should be visually inspected, for example, for defects such as porosity, cracks, and slag inclusions, as well as non-destructive testing, such as ultrasonic testing or magnetic particle testing, to ensure that the weld quality meets the construction standards. For unqualified welds detected, defects can be removed by carbon arc gouging or grinding with a grinding wheel, and then re-welded and inspected. The weld quality meets the construction quality standards.

[0065] Furthermore, refer to Figure 10 and Figure 11 As shown, in some embodiments, it further includes a third functional layer 8, which is connected to the wall panel of the connecting plate 22 and the storage tank 3, and the third functional layer 8 covers the third connecting surface 9c of the connecting member 9, and the third functional layer 8 has waterproof sealing and anti-corrosion functions.

[0066] Specifically, in the technical solution adopted in this application, the third functional layer 8 can be a protective layer with a layered structure formed by applying epoxy coal tar paint and waterproof sealant at the connection between the wall panel of the storage tank 3 and the embedded part 2. The waterproof sealant can be, for example, polyurethane waterproof sealant, silicone waterproof sealant, or acrylic waterproof sealant.
