Description

Technical Field

[0001] This invention relates to the field of structural technology for water treatment systems, and more specifically, to a double-layer combined water tank anti-displacement cooperative support structure. Background Technology

[0002] In the raw water pretreatment system of a power plant, the fire-fighting pool and the mechanically accelerated clarification pool (mechanical agitation pool) are core structures that ensure the water treatment process and fire safety. The mechanical agitation pool accelerates the sedimentation of suspended particles through mechanical agitation, and its operational stability directly affects the influent water quality of the subsequent desalination system; the fire-fighting pool serves as an emergency backup water source, providing critical water support for the entire plant's fire protection system.

[0003] Currently, such facilities generally employ cast-in-place concrete structures or traditional steel structures for support, distributing the load through raft foundations and relying on bolts or welding to connect the pool body to the support frame. With the expansion of power plant scale and the increase in water treatment volume, existing machined pool support structures have significant limitations in terms of high-precision installation and adjustment—minor foundation settlement or construction errors can easily lead to horizontal displacement of the pool body, thus affecting the coaxiality of the agitator and reducing sedimentation efficiency; simultaneously, rigid support systems are difficult to adapt to geological deformation, easily causing stress concentration cracks in the base plate in soft soil areas, threatening the structure's sealing and durability.

[0004] In terms of structural load-bearing coordination, traditional machined pool supports often employ a unidirectional load transmission path, with the load directly transferred to the foundation through the columns, lacking a multi-level load distribution mechanism. This design is prone to localized stress exceeding limits under full-water conditions or equipment vibration, leading to fatigue cracking of the support components. Cracks and leaks can further increase the risk of cross-contamination between the fire-fighting pool and the machined pool. In addition, fire-fighting pools are often arranged adjacent to machined pools to save space, but if the foundations of the two are not integrated and coordinated, differential displacement during an earthquake may cause the connecting pipes to break, thereby weakening the reliability of the fire-fighting water supply.

[0005] Current construction techniques still primarily rely on on-site casting and segmented hoisting. Each supporting component of the tank needs to be individually welded, a time-consuming and labor-intensive process whose precision depends heavily on manual experience. Because the curved bottom surface of the machined tank needs to precisely fit the supporting structure, traditional supports lack curvature self-adaptation capabilities, often requiring post-construction grouting to fill gaps. This not only prolongs the construction period but also causes uneven load distribution at the tank bottom, accelerating tank wall deformation. Furthermore, the need for rapid construction of fire-fighting tanks conflicts with the precision installation requirements of machined tanks; the low standardization of the support system cannot simultaneously optimize the construction period for both. These combined problems lead to potential risks in the raw water pretreatment system, including frequent downtime for maintenance, water quality fluctuations, and insufficient emergency response capabilities.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0007] To address the problems in related technologies, this invention proposes a double-layer combined water tank anti-displacement collaborative support structure to overcome the aforementioned technical problems existing in the prior art.

[0008] Therefore, the specific technical solution adopted by the present invention is as follows: A double-layer composite water tank anti-displacement cooperative support structure includes: Raft foundation, laid at the bottom of the fire pool; Fixed base columns are installed at the four corners of the raft foundation. The column adjustment assembly is set at the top of the fixed base column, and the top of the column adjustment assembly is equipped with a prefabricated adjustable top column with adjustable height. The co-load-bearing component is located between two adjacent fixed base columns; The pool body support component is located between two cooperating force-bearing components and supports the machining pool at its top. The pool body support component and the cooperating force-bearing components work together to distribute the force on the machining pool and ensure the stability of the machining pool. The anti-deviation component is installed between four prefabricated adjustable top columns to fix and position the machining tank and prevent lateral slippage.

[0009] Furthermore, in order to utilize the raft foundation as the load-bearing platform of the overall structure, rigid anchorage is formed between the shear keyways at the four corners and the fixed bottom columns to ensure that the vertical load is evenly transferred to the foundation. A pre-embedded T-shaped steel is set at the middle position of the top of the raft foundation, and several equally spaced openings are reserved on the top of the pre-embedded T-shaped steel. Shear keyways are opened at the four corners of the top of the raft foundation. The bottom and top of the fixed bottom columns are metal steel plates with outwardly flared edges. The bottom of the fixed bottom columns and the shear keyways are filled with grout after pouring.

[0010] Furthermore, in order to drive the worm gear to rotate and precisely adjust the height of the prefabricated adjustable top column by lifting the threaded column, thereby correcting foundation settlement or construction errors in real time and ensuring the horizontal positioning accuracy of the machined pool, the column adjustment assembly includes a fixed base box set at the top of the fixed base box, a lifting top box fitted on the top of the fixed base box, bolt positioning seats on both sides of the inner side of the fixed base box, fastening bolts running through the bolt positioning seats, fastening grooves that mate with the fastening bolts on both sides of the lifting top box, and fastening nuts that mate with the fastening bolts on both sides of the lifting top box; a base column is set at the bottom of the fixed base box, a worm gear is fitted on the top of the base column, a worm gear that mates with the worm gear is set on one side of the bottom of the fixed base box, a worm gear adjustment knob is set at one end of the worm gear that runs through the fixed base box, and a lifting threaded column that mates with the worm gear is set at the top of the lifting top box; a tightening slot that mates with the worm gear adjustment knob is opened on one side of the lifting top box.

[0011] Furthermore, to achieve self-locking lifting by utilizing the internal thread of the worm gear and the lifting threaded column to prevent settling and rebound, the hexagonal structure of the bolt positioning seat constrains the circumferential rotation of the fastening bolt, ensuring unidirectional transmission of locking force. The sealing design at the connection between the sealing sleeve and the worm gear isolates mud and water erosion, ensuring the long-term reliability of the adjustment mechanism. The bottom column has a T-shaped structure and is hollow inside. The bottom of the worm gear is fitted on the outside of the T-shaped structure of the bottom column to maintain a movable connection. The inside of the worm gear has an internal thread structure that mates with the lifting threaded column. Both the inside of the bolt positioning seat and the end of the fastening bolt have hexagonal structures to keep the fastening bolt in a stationary state. The end face of the bolt positioning seat is fitted with a sealing sleeve, and the connection between the worm gear and the fixed base box adopts a sealing design.

[0012] Furthermore, to ensure the bottom of the fixed base box is connected to the top of the fixed base column via bolts using an outwardly expanding steel plate, the top of the lifting top box is connected to the prefabricated adjustable top column in the same way, forming a standardized node. Metal sleeves are fitted onto the column and tightened with bolts to enhance the axial force transmission efficiency between the fixed base column and the prefabricated adjustable top column. Both the bottom of the fixed base box and the top of the lifting top box are designed with outwardly expanding metal steel plates. The bottom of the fixed base box is fixedly connected to the top of the fixed base column with bolts, and the top of the lifting top box is fixedly connected to the bottom of the prefabricated adjustable top column with bolts. Metal sleeves are fitted onto the top of the fixed base column and the bottom of the prefabricated adjustable top column, and both are fixedly connected with bolts. The upper and lower metal sleeves are symmetrical to each other.

[0013] Furthermore, in order to connect the bow-shaped connecting plate to the column via metal sleeves, the metal beam head is bolted to the main support beam to form a horizontal force transmission frame; the distributed support columns are equidistantly distributed through snap-fit ​​mounting plates to transfer the load of the main support beam to the raft foundation in stages, avoiding stress concentration. The coordinating force-bearing components include a bow-shaped connecting plate between two metal sleeves, a metal beam head on one side of the bow-shaped connecting plate, a main support beam between two metal beam heads on one side, several equidistantly arranged snap-fit ​​mounting plates at the bottom of the main support beam, and distributed support columns at the bottom of the snap-fit ​​mounting plates.

[0014] Furthermore, in order to provide vertical adjustment margin with the help of adjustable holes to accommodate on-site installation errors, bolts are used to connect metal sleeves through the adjustable holes to achieve modular and rapid positioning of the main support beam. The top of the bow-shaped connecting plate has multiple adjustable holes, and the bow-shaped connecting plate is bolted to the metal sleeves on the outside of the prefabricated adjustable top column through the adjustable holes. The top and bottom of the metal beam head also have adjustable holes, and the metal beam head is bolted to the bow-shaped connecting plate through the adjustable holes.

[0015] Furthermore, to ensure self-alignment and splicing through the snap-fit ​​protrusions and snap-fit ​​grooves, the inner wall curvature is precisely matched to the machined pool bottom; the annular seat plate is bolted to fix the arc-shaped seat group, and the bottom supporting longitudinal beam is bolted to the main supporting beam through the beam head connecting plate, forming a load transfer chain of "curved surface support, longitudinal beam dispersion, and main beam integration". The pool body support component includes multiple supporting arc-shaped seats spliced ​​end to end, with end face connecting plates at both ends of the supporting arc-shaped seats. One end of the supporting arc-shaped seat has a snap-fit ​​protrusion, and the other end of the supporting arc-shaped seat has a snap-fit ​​groove. The bottom end of the supporting arc-shaped seats is provided with an arc-shaped reinforcing rib; the bottom end of the supporting arc-shaped seats spliced ​​into an annular structure is provided with an annular seat plate, and the annular seat plate is fixed to the bottom of the supporting arc-shaped seats with bolts; the bottom end of the annular seat plate is provided with multiple equidistant connecting crossbeams, and the bottom end of the connecting crossbeams is provided with multiple equidistant supporting longitudinal beams; beam head connecting plates are provided at both ends of the supporting longitudinal beams.

[0016] Furthermore, to enhance bending stiffness by utilizing the arc-shaped structure of the supporting longitudinal beams and the reinforcing bottom ribs, and to ensure close contact and force transmission with the main supporting beams, the L-shaped design of the beam head connecting plate provides three-dimensional constraints to prevent the pool support components from dislodging under vibration conditions. The supporting longitudinal beams are arc-shaped, and reinforcing bottom ribs are provided at the bottom of the supporting longitudinal beams. The beam head connecting plate is L-shaped, and the beam head connecting plate is in close contact with the main supporting beam and is fixedly connected by bolts. The inner wall of the supporting arc-shaped seat is in close contact with the bottom structure of the machined pool.

[0017] Furthermore, in order to fix the top seat of the anti-deviation component to the triangular bracket support at the top of the prefabricated adjustable top column, the arc-shaped hoop is tightly attached to the side wall of the machining pool; the four arc-shaped hoops are locked together by bolts on the hoop surface connecting plates to form an integral ring constraint ring, generating continuous radial pressure to suppress horizontal displacement caused by water pressure fluctuations or earthquakes. The anti-deviation component includes a top seat set at the top of the prefabricated adjustable top column, a triangular bracket set inside the top seat, an arc-shaped hoop set inside the triangular bracket, and hoop surface connecting plates at both ends of the arc-shaped hoop. The four arc-shaped hoops are fixedly connected to the bolts through the hoop surface connecting plates and form a ring structure.

[0018] The beneficial effects of this invention are as follows: 1. The rigid anchoring of the raft foundation and the four corner fixed columns forms a shear-resistant core. Combined with the precise leveling of the column adjustment components, it dynamically compensates for foundation settlement or construction deviations, effectively ensuring the horizontal accuracy of the pool. The coordinated force-bearing components form a horizontal force transmission frame, realizing graded load transfer to the foundation and significantly reducing local stress peaks. The curved support design of the pool body support components precisely matches the curvature of the pool bottom. Combined with the arc-shaped reinforcement structure of the supporting longitudinal beams, it forms a load transmission chain of "curved support, longitudinal beam dispersion, and main beam integration," achieving uniform load distribution. The ring constraint ring of the anti-deviation component applies continuous radial pressure, effectively suppressing lateral slippage of the pool. The overall structure, with its coordinated mechanism of "shear anchoring - dynamic leveling - dispersed force transmission - radial anti-deviation," significantly improves the stability and durability of the double-layer water tank under soft soil foundations or high-precision requirements. At the same time, the prefabricated components and adjustable hole design significantly reduce on-site work, lowering construction costs and maintenance difficulty.

[0019] 2. To ensure the overall structure's coordinated stress distribution and precise adjustment capabilities, the raft foundation serves as the core load-bearing platform, with initial positioning achieved through fixed base columns at the four corners. The column adjustment assembly, through the interlocking design of the fixed base box and the lifting top box combined with worm gear transmission, drives the lifting threaded column to complete the fine-tuning of the prefabricated adjustable top column height, ensuring the horizontal accuracy of the pool structure during installation and construction.

[0020] 3. The self-aligning splicing is achieved by the snap-fit ​​protrusions and snap-fit ​​grooves at both ends of the supporting arc seat. Combined with the bolt fixing of the bottom annular seat plate, a supporting curved surface that perfectly matches the curvature of the machined pool bottom is formed. The supporting longitudinal beam is strengthened by reinforcing the bottom reinforcement and is modularly bolted to the main support beam of the cooperating force-bearing component by the beam head connecting plate. This eliminates local stress concentration and greatly reduces the complexity of on-site construction.

[0021] 4. Through a multi-directional constraint mechanism, the triangular brackets at the top of the four prefabricated adjustable top columns support the arc-shaped hoop segments to form a ring constraint circle. The hoop connecting plate at the end of each arc-shaped hoop segment is locked with high-strength bolts to generate radial rigid constraint force. Under the joint action of the bow-shaped connecting plate of the cooperating force-bearing component and the horizontal support network formed by the metal beam head, an all-round anti-slip protection system covering the side wall of the water tank is constructed to eliminate the risk of displacement during water treatment operation.

[0026] According to an embodiment of the present invention, a double-layer combined water tank anti-displacement cooperative support structure is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-13 As shown, the double-layer combined water tank anti-displacement cooperative support structure according to an embodiment of the present invention includes: Raft foundation 1, laid at the bottom of the fire pool; Fixed base columns 2 are respectively set at the four corners of the raft foundation 1; The column adjustment component 3 is set at the top of the fixed base column 2, and the top of the column adjustment component 3 is provided with a prefabricated adjustable top column 4 whose height position is adjustable. The cooperating force-bearing component 5 is located between two adjacent fixed base columns 2; The pool body support component 6 is located between the two cooperating force-bearing components 5, and supports the machining pool at its top. The pool body support component 6 and the cooperating force-bearing components 5 work together to achieve the distribution of force on the machining pool and ensure the stability of the machining pool. The anti-deviation component 7 is set between the four prefabricated adjustable top columns 4 to fix and position the machining tank and prevent lateral slippage.

[0028] By employing the aforementioned technical solutions, a shear-resistant core is formed through the rigid anchoring of the raft foundation 1 and the four corner fixed base columns 2. Combined with the precise leveling of the column adjustment components 3 to dynamically compensate for foundation settlement or construction deviations, the horizontal accuracy of the pool body is effectively guaranteed. The synergistic force-bearing components 5 form a horizontal force transmission frame, realizing graded load transfer to the foundation and significantly reducing local stress peaks. The curved support design of the pool body support components 6 precisely matches the curvature of the pool bottom, and combined with the arc-shaped reinforcement structure of the supporting longitudinal beams 608, a load transmission chain of "curved support, longitudinal beam dispersion, and main beam integration" is formed, achieving uniform load distribution. The annular constraint ring of the anti-deviation component 7 applies continuous radial pressure, effectively suppressing lateral slippage of the pool body. The overall structure, with its synergistic mechanism of "shear anchoring - dynamic leveling - dispersed force transmission - radial anti-deviation," significantly improves the stability and durability of the double-layer water tank under soft soil foundations or high-precision requirements. At the same time, the prefabricated components and adjustable hole design significantly reduce on-site work, lowering construction costs and maintenance difficulties.

[0029] In one embodiment, for the raft foundation described above, a pre-embedded T-shaped steel 8 is provided at the middle position of the top of the raft foundation 1, and several equidistant openings are reserved on the top of the pre-embedded T-shaped steel 8; shear keyways 9 are provided at the four corners of the top of the raft foundation 1; the bottom and top of the fixed bottom column 2 are both metal steel plates with outwardly flared edges; the bottom of the fixed bottom column 2 and the shear keyway 9 are filled with grout after pouring, thereby using the raft foundation 1 as the bearing platform of the overall structure, and forming a rigid anchorage with the fixed bottom column 2 through the shear keyways 9 at the four corners, ensuring that the vertical load is evenly transferred to the foundation.

[0030] In one embodiment, the column adjustment assembly 3 includes a fixed base box 301 disposed at the top of the fixed base column 2, a lifting top box 302 sleeved on the top of the fixed base box 301, bolt positioning seats 303 disposed on both sides of the inner side wall of the fixed base box 301, fastening bolts 304 passing through the bolt positioning seats 303, fastening grooves 305 cooperating with the fastening bolts 304 disposed on both sides of the lifting top box 302, fastening nuts 306 cooperating with the fastening bolts 304 disposed on both sides of the lifting top box 302, and a base column 307 disposed at the bottom of the fixed base box 301. A worm gear 308 is fitted on the top. A worm 309 that cooperates with the worm gear 308 is provided on one side of the bottom of the fixed base box 301.

A tightening slot 312 that cooperates with the worm adjustment knob 310 is opened on one side of the lifting top box 302. Thus, the worm gear 308 is driven to rotate by the worm 309, which drives the lifting threaded column 311 to precisely adjust the height of the prefabricated adjustable top column 4. This can correct foundation settlement or construction errors in real time and ensure the horizontal positioning accuracy of the machined pool.

[0031] In one embodiment, the base column 307 is a T-shaped structure with a hollow interior. The bottom of the worm gear 308 is fitted onto the outside of the T-shaped structure of the base column 307 for a movable connection. The interior of the worm gear 308 has an internal thread structure that mates with the lifting threaded column 311. The bolt positioning seat 303 and the end of the fastening bolt 304 are both hexagonal structures to keep the fastening bolt 304 stationary. A sealing sleeve 313 is fitted on the end face of the bolt positioning seat 303. The connection between the worm 309 and the fixed base box 301 is sealed. This allows for self-locking lifting by utilizing the internal thread of the worm gear 308 in conjunction with the lifting threaded column 311, preventing sinking and rebound. The hexagonal structure of the bolt positioning seat 303 constrains the circumferential rotation of the fastening bolt 304, ensuring unidirectional transmission of the locking force. The sealing design at the connection between the sealing sleeve 313 and the worm 309 isolates mud and water erosion, ensuring the long-term reliability of the adjustment mechanism.

[0032] In one embodiment, for the aforementioned fixed base box 301, both the bottom end of the fixed base box 301 and the top end of the lifting top box 302 are designed with outward-expanding metal steel plates.

The metal sleeves 10 are fitted onto the column body and tightened by bolts, which enhances the axial force transmission efficiency between the fixed base column 2 and the prefabricated adjustable top column 4.

[0033] In one embodiment, the aforementioned collaborative load-bearing component 5 includes an arc-shaped connecting plate 501 positioned between two upper and lower metal sleeves 10. A metal beam head 502 is provided on one side of the arc-shaped connecting plate 501, and a main support beam 503 is provided between the two metal beam heads 502 on one side. Several equally spaced snap-fit ​​mounting plates 504 are provided at the bottom of the main support beam 503, and distributed support columns 505 are provided at the bottom of the snap-fit ​​mounting plates 504. Thus, the arc-shaped connecting plate 501 is connected to the column through the metal sleeves 10, and the metal beam head 502 is bolted to the main support beam 503 to form a horizontal force transmission frame. The distributed support columns 505 are equally spaced through the snap-fit ​​mounting plates 504, which transfers the load of the main support beam 503 to the raft foundation 1 in stages, avoiding stress concentration.

[0034] In one embodiment, the bow-shaped connecting plate 501 has multiple adjustable holes 506 at its top. The bow-shaped connecting plate 501 is bolted to the metal sleeve 10 on the outside of the prefabricated adjustable top column 4 through the adjustable holes 506. The metal beam head 502 also has adjustable holes 506 at its top and bottom. The metal beam head 502 is bolted to the bow-shaped connecting plate 501 through the adjustable holes 506, thereby providing vertical adjustment margin to accommodate on-site installation errors. Bolts pass through the adjustable holes 506 to connect the metal sleeve 10, realizing modular and rapid positioning of the main support beam 503.

[0035] In one embodiment, the pool body support assembly 6 includes multiple end-to-end spliced ​​arc-shaped support seats 601. Each arc-shaped support seat 601 has an end-face connecting plate 602 at both ends, a snap-fit ​​protrusion 603 at one end, a snap-fit ​​groove 604 at the other end, and an arc-shaped reinforcing rib 605 at the bottom. An annular seat plate 606 is provided at the bottom of the arc-shaped support seats 601, which are spliced ​​into a ring structure. The annular seat plate 606 is bolted to the bottom of the arc-shaped support seats 601. Fixed connection; the bottom end of the annular seat plate 606 is provided with multiple equidistant connecting crossbeams 607, and the bottom end of the connecting crossbeams 607 is provided with multiple equidistant supporting longitudinal beams 608; the beam head connecting plates 609 are provided at both ends of the supporting longitudinal beams 608, so that they can be self-aligned and spliced ​​by the snap-fit ​​protrusions 603 and snap-fit ​​grooves 604, and the inner wall curvature is precisely matched to the machined pool bottom; the annular seat plate 606 is bolted to fix the arc-shaped seat group, and the bottom supporting longitudinal beams 608 are bolted to the main supporting beams 503 through the beam head connecting plates 609, forming a load transfer chain of "curved surface support, longitudinal beam dispersion, and main beam integration".

[0036] In one embodiment, the supporting longitudinal beam 608 has an arc-shaped structure and a reinforcing rib 610 at its bottom. The beam head connecting plate 609 has an L-shaped structure and is fitted to the main supporting beam 503 and fixedly connected by bolts. The inner wall of the supporting arc-shaped seat 601 fits against the bottom structure of the machined pool, thereby utilizing the arc-shaped structure of the supporting longitudinal beam 608 and the reinforcing rib 610 to enhance the bending stiffness and ensure the fit and force transmission with the main supporting beam 503. The L-shaped design of the beam head connecting plate 609 provides three-dimensional constraint to prevent the pool body support assembly 6 from dislodging under vibration conditions.

[0037] In one embodiment, the anti-deviation component 7 includes a top seat 701 disposed at the top of the prefabricated adjustable top column 4. A triangular bracket 702 is disposed inside the top seat 701, and an arc-shaped hoop 703 is disposed inside the triangular bracket 702. Both ends of the arc-shaped hoop 703 are provided with hoop surface connecting plates 704. The four arc-shaped hoops 703 are fixedly connected to the top of the prefabricated adjustable top column 4 by bolts through the hoop surface connecting plates 704 and form a ring structure. Thus, the top seat 701 of the anti-deviation component 7 is fixed to the triangular bracket 702 at the top of the prefabricated adjustable top column 4, supporting the arc-shaped hoop 703 to be close to the side wall of the machining pool. The four arc-shaped hoops 703 are bolted together by the hoop surface connecting plates 704 to form an integral ring constraint ring, generating continuous radial pressure to suppress horizontal displacement caused by water pressure fluctuations or earthquakes.

[0038] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0039] In practical applications, the raft foundation 1 is first laid at the bottom of the fire pool. The shear keyways 9 at its four corners are filled with grout and fitted with the outwardly expanded steel plates at the bottom of the fixed base column 2 to form shear anchoring nodes, ensuring that the vertical load is transferred to the foundation. The pre-embedded T-shaped steel 8 in the middle of the raft foundation provides shear stiffness, and the opening at the top facilitates pipeline penetration or equipment installation, while also serving as a positioning reference for the upper structure. After the fixed base column 2 is installed, the top is connected to the column adjustment assembly 3. By rotating the worm gear adjustment knob 310, the worm gear 309 is driven to mesh with the worm wheel 308, which drives the lifting threaded column 311 to precisely lift and lower, realizing the height adjustment of the prefabricated adjustable top column 4 to compensate for foundation settlement or construction errors. After leveling, the fastening bolts 304 are inserted into the fastening grooves 305 of the lifting top box 302 and the fastening nuts 306 are tightened to lock the position of the lifting top box 302; the sealing sleeve 313 and the worm gear sealing design can isolate mud and water erosion and ensure long-term reliability.

[0040] The prefabricated adjustable top column 4 is fitted with metal sleeves 10 at both the bottom and top, and fixed with bolts. The bow-shaped connecting plate 501 of the cooperative force-bearing component 5 is bolted to the metal sleeves 10 using adjustable positioning holes 506 to achieve position adjustment. The main support beam 503 is bolted to the bow-shaped connecting plate 501 via a metal beam head 502, and the bottom is fixed to the distributed support column 505 via a snap-fit ​​mounting plate 504, forming a three-level force transmission path of "main beam, distributed column, foundation" to avoid stress concentration. The support arc-shaped seat 601 of the pool body support component 6 is self-aligned and spliced ​​into a ring by snap-fit ​​protrusions 603 and snap-fit ​​grooves 604, and the inner wall curvature is precisely matched to the machined pool bottom. An annular seat plate 606 is bolted to a fixed arc-shaped seat group. The bottom supporting longitudinal beam 608 is bolted to the main supporting beam 503 via an L-shaped beam head connecting plate 609, evenly transferring the pool load to the coordinating force-bearing component 5. The arc-shaped structure of the supporting longitudinal beam 608 and the reinforcing bottom rib 610 enhance bending stiffness and prevent local deformation. Anti-deviation components 7 are installed at the top of four prefabricated adjustable top columns 4, and their top seats 701 support triangular brackets 702 to fix arc-shaped hoops 703. The four arc-shaped hoops 703 are bolted together to form an annular constraint ring through the hoop surface connecting plate 704, applying continuous radial pressure to the side wall of the machined pool, forming a horizontal anti-slip barrier to resist lateral slippage caused by water pressure fluctuations or earthquakes.

[0041] The final load transfer path is "machined pool, supporting arc seat 601, supporting longitudinal beam 608, main supporting beam 503, distributed supporting column 505, raft foundation", realizing multi-level distributed force; the dynamic leveling of column adjustment component 3 and the horizontal constraint of anti-deviation component 7 form a closed loop control to ensure the stability of the double-layer water pool under working conditions such as full water, empty pool and micro-deformation of foundation.

[0042] In summary, by utilizing the above-mentioned technical solution of the present invention, and considering the coordinated force and precise adjustment capabilities of the overall structure, the raft foundation 1 serves as the core bearing platform, and the initial positioning is achieved through the four corner fixed base columns 2. The column adjustment assembly 3, through the sleeve design of the fixed base box 301 and the lifting top box 302 combined with the worm gear 308 and worm 309 transmission, drives the lifting threaded column 311 to complete the height fine adjustment of the prefabricated adjustable top column 4, ensuring the horizontal accuracy of the pool structure during the installation and construction process.

[0043] Self-alignment and splicing are achieved through the snap-fit ​​protrusions 603 and snap-fit ​​grooves 604 at both ends of the arc-shaped seat 601. Combined with the bolt fixing of the bottom annular seat plate 606, a support surface perfectly matches the curvature of the machined pool bottom is formed. The supporting longitudinal beam 608 is reinforced with bottom reinforcement 610 and modularly bolted to the main support beam 503 of the cooperating force-bearing component 5 by the beam head connecting plate 609. This eliminates local stress concentration and significantly reduces on-site construction complexity. Through a multi-directional constraint mechanism, the triangular brackets 702 at the top of the four prefabricated adjustable top columns 4 respectively support the arc-shaped hoop 703 segments to form an annular constraint ring. The hoop surface connecting plate 704 at the end of each arc-shaped hoop 703 segment is locked with high-strength bolts to generate radial rigid constraint force. Under the combined action of the horizontal support network formed by the bow-shaped connecting plate 501 and the metal beam head 502 of the cooperating force-bearing component 5, a comprehensive anti-slip protection system covering the sidewalls of the pool is constructed, eliminating displacement risks during water treatment operation.
