Technical Field

[0001] This invention belongs to the field of winter construction technology, specifically relating to an auxiliary device and construction method for low-temperature construction of the main body of a mine water treatment station in winter. Background Technology

[0002] In mine water treatment, multiple stages of purification are required, including influent regulating tanks, aeration tanks, sedimentation tanks, and purification tanks. The construction quality of each tank directly affects the efficiency and stability of mine water treatment. Traditional mine water treatment tanks often use cast-in-place concrete. In low-temperature winter environments, cast-in-place concrete is susceptible to freezing-thaw damage and slow strength development, making it difficult to guarantee construction quality. Freezing heave of the foundation can easily lead to cracking and leakage in the tank, affecting structural durability. The construction process is complex, time-consuming, and often involves work stoppages during winter.

[0003] Therefore, developing a mine water treatment tank that is suitable for low-temperature construction in winter, modularly assembled, structurally stable, waterproof, and has multiple additional functions has become an urgent technical problem to be solved. Summary of the Invention

[0027] The third T-shaped strip is fitted with a second fastening bolt in the plate area of ​​the inner wall of the transverse wall panel. The second fastening bolt is fitted with the second threaded pipe and locked in place by threads.

[0028] Furthermore, a horizontal wall panel leveling assembly is installed below the bottommost horizontal wall panel. This assembly includes a U-shaped plate and a second screw. The second screw vertically passes through a threaded hole on the horizontal plate of the U-shaped plate and engages with it.

[0035] The top surface of the support block abuts against the bottom surface of the bottom longitudinal wall panel, the vertical section of the L-shaped tube is inserted into the second tube, and the horizontal section of the L-shaped tube is inserted into the first tube of the base plate.

[0036] A construction process for a mine water treatment pond suitable for winter construction includes the following steps: S01 Precast Slab Production: In a constant temperature workshop of 15-25℃, waterproof and frost-resistant concrete with added antifreeze and air-entraining agents is used to produce the base slab, transverse wall panels and longitudinal wall panels. The transverse wall panels and longitudinal wall panels are precast in sections according to the height of the pool. The precast slabs are shipped after the strength reaches more than 85% of the design strength.

[0037] S02 Foundation Pit Pretreatment: Excavate the foundation pit according to the design requirements, and flatten and compact the bottom surface of the foundation pit to ensure that the flatness error of the bottom surface of the foundation pit is ≤1cm, and there is no need to lay a plain concrete cushion layer.

[0038] S03 Base Plate Leveling Component Layout: On the compacted foundation pit bottom surface, corresponding to the leveling holes on the base plate, the base plate leveling components are laid out in a rectangular array of 4 for each base plate.

[0039] S04 Base Plate Lifting and Leveling: Lift the precast base plate into the foundation pit, ensuring that the leveling holes of the base plate are precisely aligned with the first screw of the base plate leveling assembly. Adjust the levelness of the base plate by rotating the first screw, ensuring that the flatness error of a single base plate is ≤1mm and the height difference between the top surfaces of adjacent base plates is ≤0.5mm. After leveling, seal the leveling holes.

[0040] S05 Base Plate Splicing, Fixing and Sealing: The splicing and fixing of adjacent base plates is achieved by using the base plate horizontal connecting components, the base plate longitudinal connecting components and U-shaped rods. After cleaning the splicing gaps, low-temperature two-component polysulfide sealant is filled in, and carbon fiber cloth is laid for protection after curing.

[0041] S06 Horizontal Wall Panel Installation: Install the bottom horizontal wall panel at the corresponding position on the base plate. Seal the horizontal wall panel to the base plate using the edge sealing strip. Adjust the verticality of the horizontal wall panel using the horizontal wall panel leveling assembly and fix it in place. Use a third T-shaped strip, insert rod, and second fastening bolt to achieve a sealed connection between adjacent horizontal wall panels. Use a wall panel connecting sealing strip to achieve a sealed connection between adjacent horizontal wall panels on the same layer. Add a stainless steel bracket and expansion bolts between the inner wall of the bottom horizontal wall panel and the base plate for fixation.

[0042] S07 Longitudinal Wall Panel Installation: Longitudinal wall panels are installed using the same method as transverse wall panels. The longitudinal wall panels are sealed to the base plate using edge sealing strips. The verticality of the longitudinal wall panels is adjusted and fixed using the longitudinal wall panel leveling components. A fourth T-shaped strip, straight insertion tube, and second fastening bolt are used to achieve a sealed connection between adjacent vertical longitudinal wall panels. A wall panel connecting sealing strip is used to achieve a sealed connection between adjacent longitudinal wall panels on the same floor. Stainless steel brackets and expansion bolts are added between the inner wall of the bottom longitudinal wall panel and the base plate for fixation.

[0043] S08 Corner Seal: At the corner where the horizontal wall panel and the vertical wall panel intersect, a vertically installed corner sealing strip is used for sealing and connection.

[0044] S09 Overall Waterproofing and Sealing Treatment: The process involves sequentially treating the substrate, constructing internal waterproofing, reinforcing waterproofing at key points, and constructing external waterproofing. Substrate treatment includes cleaning the surface of the panels, drying them, and repairing cracks and holes. Internal waterproofing involves applying two coats of low-temperature cement-based penetrating crystalline waterproofing coating with a thickness ≥1.5mm to the inside of the pool and curing for ≥7 days. Reinforcing waterproofing at key points involves applying an additional low-temperature polyurethane waterproofing coating to leak-prone areas and laying an additional layer of waterproof membrane. External waterproofing involves laying a low-temperature SBS modified bitumen waterproof membrane inside the pool and hot-melt welding it, with a polyurethane insulation layer laid on the outside of the membrane.

[0045] Compared with the prior art, the present invention has the following beneficial effects: Significant beneficial effects of the present invention (1) The base slab, transverse wall panels and longitudinal wall panels are prefabricated in the factory under constant temperature, so that the concrete solidification is not affected by the low temperature in winter, thus ensuring its own strength. The entire water tank is assembled in a modular manner, which improves the construction efficiency by more than 50%, shortens the construction period by 30%, and enables continuous construction in winter.

[0046] (2) By using base plate leveling components, mechanical fixing, flexible sealing, triple waterproofing and other processes, the core difficulties of flatness, splicing and waterproofing during winter construction can be solved.

[0047] (3) A constant-temperature medium is introduced through the first and second pipes running through the bottom plate to heat the foundation of the pool throughout the entire area, eliminating frozen soil, inhibiting frost heave, and preventing cracking and misalignment of the pool bottom. This is suitable for low-temperature construction from -15℃ to -30℃. At the same time, dry hot air can be introduced to dry the residual moisture in the joints, prevent freezing and cracking of the sealing layer, and ensure the reliability of the seal. During daily use, the channel formed by the first and second pipes can also be circulated with warm water to maintain the constant temperature heat storage of the bottom plate, thereby improving the strength of the precast slab. (4) The through channel formed by the first pipe and the second pipe forms a hollow buffer corridor, which releases the rigidity of the bottom plate, can buffer local settlement and frost heave of the foundation, avoid stress concentration leading to slab fracture, and eliminates the need for high-standard foundation treatment, thus greatly reducing construction costs.

[0048] (5) The hollow channels such as the first pipe, the second pipe and the sleeve are pre-embedded to reduce the self-weight of the base plate, reduce the difficulty of hoisting and the cost of prefabrication, and reduce the pressure of the foundation. They can also be used as grouting channels in the later stage to achieve excavation-free concealed reinforcement, improve maintainability, and take into account the needs of continuous construction in winter.

Detailed Implementation

[0052] The accompanying drawings provide a more detailed description of the auxiliary device and construction method for low-temperature construction of the main body of the mine water treatment station in winter, but this is not intended to limit the scope of the invention.

[0053] Depend on Figures 1 to 31 As shown, a winter low-temperature construction auxiliary device for the main body of a mine water treatment station adopts a modular and detachable splicing structure, which is suitable for low-temperature construction scenarios. The whole is composed of a pool bottom assembly, a transverse side wall assembly and a longitudinal side wall assembly to form a closed water treatment pool, which takes into account both structural stability and waterproof sealing.

[0054] The pool bottom assembly is composed of several bottom plates 1 spliced ​​together. The horizontally adjacent bottom plates 1 are sealed and assembled through the horizontal connecting components of the bottom plates, and the vertically adjacent bottom plates 1 are sealed and assembled through the vertical connecting components of the bottom plates. After splicing, a complete pool bottom is formed.

[0055] The base plate 1 has a pre-embedded base plate frame 2 for support and reinforcement. The frame includes multiple spaced first pipes 201 and connecting plates 202. The connecting plates 202 are perpendicular to and fixedly connected to the first pipes 201. Both ends extend out of the base plate 1, and the extended parts are provided with threaded holes 203. The ends are also fixedly connected to vertically arranged upright plates 204. The upright plates 204 have two spaced insertion holes 205. A U-shaped rod 4 is inserted into the corresponding insertion holes 205 of the upright plates 204 of two adjacent base plates 1 to enhance the splicing firmness.

[0056] After the adjacent bottom plates 1 are assembled and connected, the first pipes 201 inside the two bottom plates 1 are precisely connected end to end and interconnected through the longitudinal connecting components, forming a closed fluid or airflow channel that runs through the entire bottom of the pool, which can realize functions such as constant temperature heating, ventilation and dehumidification.

[0057] The transverse connecting assembly of the base plate includes a first T-shaped strip 5 and a first fastening bolt 6. The first T-shaped strip 5 is fitted into the joint gap between two adjacent base plates 1. Specifically, the horizontal part of the first T-shaped strip 5 overlaps the top surface of the two adjacent base plates 1, and the vertical part of the first T-shaped strip 5 is inserted between the two base plates 1, with its bottom surface abutting against the top of the connecting plate 202. The first fastening bolt 6 passes through the through hole on the first T-shaped strip 5 and is threaded into the threaded hole 203 on the outer connecting plate 202 of the two base plates 1, and is threadedly locked in place.

[0058] The longitudinal connecting assembly of the base plate includes a second T-shaped strip 7 and a connector. The second T-shaped strip 7 has several longitudinally arranged sliding cavities 701 inside. The second T-shaped strip 7 is fitted into the joint between two adjacent longitudinal base plates 1 to optimize the sealing effect and avoid interference with the horizontal portion of the first T-shaped strip 5. In this embodiment, the bottom of the two longitudinal end faces of the base plate 1 is provided with a lower boss 102, and the top is provided with an upper recess 103. The horizontal portions of the second T-shaped strip 7 rest on both sides of the upper recesses 103 of the two base plates 1, with its top surface flush with the top surface of the base plate 1, thus avoiding interference with the laying of the first T-shaped strip 5. The bottom surface of the vertical portion of the second T-shaped strip 7 abuts against the top surface of the lower bosses 102 of the two base plates 1.

[0059] The connector consists of a rotating rod 8, a double-ended stud 9, and two sliding tubes 10. The vertically positioned rotating rod 8 is rotatably mounted on a through hole in the second T-shaped strip 7, which communicates with the sliding cavity 701. The double-ended stud 9 is coaxially positioned inside the sliding cavity 701 and is rotatably mounted to the cavity wall of the sliding cavity 701 via a bracket. The two ends of its threads rotate in opposite directions, and the rotating rod 8 can drive the double-ended stud 9 to rotate synchronously. Specifically, a first bevel gear 801 is coaxially fixed to the bottom of the rotating rod 8, and a second bevel gear 901 is coaxially fixed to the middle of the double-ended stud 9. The first bevel gear 801 and the second bevel gear 901 are meshed together.

[0060] The outer diameter of the slide tube 10 is adapted to and slidably fitted with the inner diameter of the sliding cavity 701. Several spaced limiting slide plates 1001 protrude outwards from the end, engaging with the slide rails on the inner wall of the sliding cavity 701. A first threaded tube 1002 is fixedly connected to the inner side of the slide tube 10 via a bracket, and is threadedly fitted with a double-ended stud 9. Under the action of the limiting slide plates 1001, the slide tube 10 can only slide, not rotate. Rotating the rotating rod 8 drives the double-ended stud 9 to rotate, causing the two slide tubes 10 to extend and retract along the sliding cavity 701 in opposite directions. After extending beyond the second T-shaped strip 7, the slide tube 10 is inserted into the first tube 201 of two longitudinally adjacent base plates 1, achieving a positioning connection, and the outer diameter of the slide tube 10 matches the inner diameter of the first tube 201. To further optimize the sealing effect after the sliding tube 10 and the first tube 201 are inserted, the outer wall of the sliding tube 10 is provided with several annular grooves 1003 arranged at intervals, and a sealing ring 11 is fitted inside the annular grooves 1003. The sealing ring 11 can be a rubber ring or a ring made of water-swellable material.

[0061] The base plate 1 has at least four leveling holes 101 arranged in a rectangular array, and a base plate leveling assembly 3 is disposed below it. The assembly includes a first base 301, the top surface of which has an open threaded hole, and a first screw 302 that is threaded into it is installed inside. A support ring 303 is sleeved on the outside of the first screw 302 extending above the first base 301. The top surface of the support ring 303 abuts against the bottom surface of the base plate 1 for limitation. The end of the first screw 302 above the support ring 303 is inserted into the leveling hole 101, and the levelness of the base plate 1 can be adjusted by rotating the first screw 302.

[0062] The length of the first screw 302 above the support ring 303 is less than or equal to the depth of the leveling hole 101. Simultaneously, an internal hexagonal hole 304 is recessed on the top surface of the first screw 302 to facilitate rotation of the first screw 302 using tools. After leveling the base plate 1, a sealing cap 305 is inserted into the leveling hole 101 to seal it, preventing deposited mud and sand from falling into the hole and affecting the subsequent rotation and use of the first screw 302.

[0063] The transverse sidewall assembly consists of several layers of vertically stacked transverse wall panels 12. Two adjacent transverse wall panels 12 are sealed together by a transverse wall panel connecting assembly. Two adjacent transverse wall panels 12 arranged in the same vertical column are sealed together by a vertically installed wall panel connecting sealing strip 26. The bottommost transverse wall panel 12 is sealed to the bottom plate 1 by a transverse wall panel edge sealing strip 17. The transverse wall panel edge sealing strip 17 is L-shaped, with its vertical part fitting against the inner wall of the transverse wall panel 12 and its horizontal part fitting against the top surface of the bottom plate 1. A second fastening bolt 16 passes through a through hole in its vertical part and is threadedly connected to a second threaded pipe 1302 below the transverse wall panel 12.

[0064] The transverse wall panel 12 is provided with a transverse wall panel frame 13 for support and reinforcement. The frame includes multiple vertically arranged sleeves 1301 and multiple horizontally arranged second threaded pipes 1302. The sleeves 1301 and the second threaded pipes 1302 are fixedly connected by connecting rods. The opening of the second threaded pipes 1302 is opened on the inner wall surface of the transverse wall panel 12.

[0065] The horizontal wall panel connecting assembly includes a plug rod 14 and a third T-shaped strip 15. The horizontal part of the third T-shaped strip 15 is fitted into the joint gap between two adjacent horizontal wall panels 12. The upper and lower ends of the plug rod 14 are respectively inserted into the corresponding sleeves 1301 inside the two adjacent horizontal wall panels 12. A support plate is provided in the middle of the plug rod 14. The support plate is placed between the two horizontal wall panels 12, and its thickness is less than the thickness of the horizontal part of the third T-shaped strip 15, which prevents the plug rod 14 from falling off and does not affect the sealing of the connection between the two horizontal wall panels 12.

[0066] The third T-shaped strip 15 is attached to the plate area of ​​the inner wall of the upper and lower horizontal wall panels 12, and a second fastening bolt 16 is inserted and threadedly locked to the second threaded pipe 1302.

[0067] Below the bottommost horizontal wall panel 12, a horizontal wall panel leveling assembly 18 is installed. This assembly includes a U-shaped plate 1801 and a second screw 1802. The second screw 1802 vertically passes through a threaded hole on the horizontal plate of the U-shaped plate 1801 and is threaded into it. The end of the second screw 1802 extending above the U-shaped plate 1801 is inserted into a sleeve 1301 inside the bottommost horizontal wall panel 12. Two mounting through holes are provided on the vertical plate of the U-shaped plate 1801, which are fixed to the vertical plate 204 of the base plate 1 by U-shaped rods 4.

[0068] The bottom of the second screw 1802 is provided with a disc or seat to reduce pressure and prevent the bottom of the second screw 1802 from being inserted into the bottom of the pit under pressure.

[0069] To improve the sealing effect and connection strength between adjacent transverse wall panels 12 on the same floor, a first side boss 1201 protrudes from the outer side of the horizontal end face of the transverse wall panel 12. The outer wall of the wall panel connecting sealing strip 26 abuts against the inner wall of the two first side bosses 1201. Threaded holes or nut sleeves are provided on the first side bosses 1201. The wall panel connecting sealing strip 26 has through holes, and bolts threaded into the through holes are threaded onto the nut sleeves. The two adjacent transverse wall panels 12 on the same floor are fixedly connected by the bolts and the wall panel connecting sealing strip 26.

[0070] The longitudinal sidewall assembly consists of several layers of vertically stacked longitudinal wall panels 19. The structure is adapted to the transverse sidewall assembly. Two adjacent longitudinal wall panels 19 are sealed and connected by a longitudinal wall panel connecting assembly. Two adjacent longitudinal wall panels 19 arranged in the same vertical column are sealed and connected by a vertically set wall panel connecting sealing strip 26. The bottom longitudinal wall panel 19 is sealed and bonded to the bottom plate 1 by a longitudinal wall panel sealing strip 23.

[0071] The bottom of the longitudinal wall panel sealing strip 23 is provided with a lower insert strip 2301, which is inserted into the inner wall of the upper recess 103 of the lower base plate 1 to improve the sealing effect on the side. The second fastening bolt 16 passes through the through hole on the longitudinal wall panel sealing strip 23 and is threaded to the third threaded tube 2002 inside the lower part of the longitudinal wall panel 19.

[0072] In order to improve the sealing effect and connection strength between adjacent longitudinal wall panels 19 on the same floor, a second side boss 1901 is provided on the outer side of the horizontal end face of the longitudinal wall panel 19. The wall panel connecting sealing strip 26 is directly sealed and fixedly connected to the two second side bosses 1901 in the same way as the first side boss 1201.

[0073] The longitudinal wall panel 19 is provided with a longitudinal wall panel frame 20 for support and reinforcement. The frame includes multiple vertically arranged second pipes 2001 and multiple horizontally arranged third threaded pipes 2002. The second pipes 2001 and the third threaded pipes 2002 are fixedly connected by connecting rods. The opening of the third threaded pipe 2002 is opened on the inner wall surface of the longitudinal wall panel 19.

[0074] The longitudinal wall panel connecting assembly includes a straight insertion tube 21 and a fourth T-shaped strip 22. The horizontal part of the fourth T-shaped strip 22 is fitted into the joint gap between two adjacent longitudinal wall panels 19. The upper and lower ends of the straight insertion tube 21 are respectively inserted into the corresponding second tubes 2001 inside the two adjacent longitudinal wall panels 19, and the outer diameter of the straight insertion tube 21 is adapted to the inner diameter of the second tube 2001. A support plate is provided in the middle of the straight insertion tube 21. The support plate is placed between the two longitudinal wall panels 19, and its thickness is less than the thickness of the horizontal part of the fourth T-shaped strip 22, which prevents the straight insertion tube 21 from falling off and does not affect the sealing of the connection between the two longitudinal wall panels 19.

[0075] The vertical part of the fourth T-shaped strip 22 is fitted with the plate area of ​​the inner wall of two adjacent longitudinal wall panels 19, and a second fastening bolt 16 is inserted and threadedly locked with the third threaded pipe 2002.

[0076] Below the bottommost longitudinal wall panel 19, a longitudinal wall panel leveling assembly 24 is installed. This assembly includes a second base 2401, a third screw 2402, a connecting plate 2403, a support block 2404, and an L-shaped insert 2405. The top surface of the second base 2401 has an open threaded hole, into which the third screw 2402 is fitted and threaded. The top end of the third screw 2402, extending above the second base 2401, is fixedly connected to the connecting plate 2403. The connecting plate 2403 is fixedly equipped with spaced-apart support blocks 2404 and L-shaped inserts 2405. The top surface of the support block 2404 abuts against the bottom surface of the bottommost longitudinal wall panel 19 for support. The vertical section of the L-shaped insert 2405 is inserted into the second tube 2001, and the horizontal section is inserted into the first tube 201 of the base plate 1, connecting the first tube 201 and the second tube 2001 through and enhancing connection stability.

[0077] At the corner where the transverse sidewall assembly and the longitudinal sidewall assembly intersect, a vertically installed corner sealing strip 25 is used for sealing and connection to ensure no leakage at the corner. To ensure the strength of the corner sealing strip 25, it consists of an inner metal square tube 2502 and an outer rubber sleeve 2501. Its sidewall includes two slots, into which a first side boss 1201 and a second side boss 1901 are respectively inserted. To improve the strength at the corner, the transverse wall panel 12 and the longitudinal wall panel 19 at the corner are fixedly connected by an L-shaped stainless steel plate and expansion bolts.

[0078] The first pipe 201 of the base slab frame 2, the sleeve 1301 of the transverse wall panel frame 13, and the second pipe 2001 of the longitudinal wall panel frame 20 together form a continuous hollow buffer corridor inside the base slab 1, the transverse wall panel 12, and the longitudinal wall panel 19. Compared with the traditional solid slab structure, this corridor can moderately release the overall stiffness of the three components, breaking the limitations of rigid slabs and giving the structure a certain degree of flexible buffering capacity. When local slight settlement or frost heave occurs in the foundation, the through circular pipe channel can generate a small deformation to buffer stress, effectively avoiding the problems of precast slab breakage and joint cracking caused by stress concentration. This greatly improves the structure's adaptability to the foundation, eliminating the need for strict ultra-high standard foundation treatment processes, and thus significantly reducing the overall cost of foundation construction. This effect breaks through the conventional understanding that circular pipes are only used as fluid channels, giving them the mechanical functions of structural buffering, anti-settlement, and anti-frost heave.

[0079] Meanwhile, multiple through holes are provided on the circumferential surfaces of the first pipe 201 and the second pipe 2001, allowing their inner cavities to communicate with the gaps in the concrete of point 1 and the longitudinal wall panel 19. This circular pipe channel formed by the first pipe 201 and the second pipe 2001 can connect with external ventilation openings, creating a permanent passive ventilation corridor. This corridor can continuously remove moisture and corrosive gases from the bottom slab and the interior of the slab, fundamentally preventing problems such as steel reinforcement corrosion, concrete alkali corrosion, and corrosion and aging of embedded connectors. It is particularly suitable for the special construction environment of high corrosion and high humidity in mine water, effectively extending the service life of the pool bottom structure. This represents a functional upgrade from a temporary insulation channel to a permanent anti-corrosion ventilation structure, a breakthrough not found in conventional precast slab structures.

[0080] In winter construction scenarios, the circular pipes of all precast slabs are connected to form a complete integrated pipe network. Centralized heating at one end is sufficient to achieve synchronous heating of the entire pool bottom, ensuring uniform temperature across the entire slab surface without any localized low-temperature dead zones. Simultaneously, the joint sealing materials and connection nodes are kept at a suitable curing temperature, significantly improving the curing quality of the sealant in low-temperature environments. This completely eliminates the tedious process of setting up insulation facilities and localized heating in each area during traditional construction, forming a pool bottom temperature control structure with built-in underfloor heating. This achieves the unexpected effect of single-point heating and overall temperature control, significantly improving the efficiency of winter construction.

[0081] Furthermore, the design of pre-embedded hollow circular tubes inside the precast slabs significantly reduces the self-weight of precast slabs of the same volume without affecting structural strength. This not only makes winter hoisting operations safer, eliminating the need for large lifting equipment, but also reduces the amount of concrete used, thus lowering the production and manufacturing costs of the precast slabs. At the same time, the reduced self-weight of the base slab also reduces the pressure on the ground surface, further weakening the requirements for the bearing capacity of the foundation. This achieves an organic combination of fluid channels and weight-reducing hollow structures, achieving two goals at once and bringing multiple hidden benefits.

[0082] This through-tube channel also has long-term maintainability. If problems such as micro-cracks in the joints or hollowing of the foundation occur in the pool later, there is no need to break the bottom plate or affect the normal operation of the pool. The original through-tube can be used as a pre-embedded grouting channel. Reinforcing materials such as ultrafine cement grout and epoxy grout are injected into the channel under low pressure. The grout can spread evenly along the channel to each joint and the hollow layer under the plate, achieving hidden reinforcement without excavation. This transforms the reserved fluid channel into a permanent pre-embedded grouting pipe, giving the structure the function of secondary reinforcement and convenient maintenance, and further improving the durability and practicality of the structure.

[0083] A construction method for building the aforementioned water treatment tank includes the following steps: S01 precast slab production: Precast cement panels, including the base slab 1, transverse wall panels 12, and longitudinal wall panels 19, are produced in a constant-temperature workshop with the temperature controlled between 15 and 25°C. C35 waterproof and frost-resistant concrete is used, with antifreeze agents and air-entraining agents added to ensure that the strength of the precast panels is ≥85% of the design strength before leaving the factory, thus preventing brittleness during winter transportation and installation. Transverse wall panels 12 and longitudinal wall panels 19 are precast in sections according to the height of the pool.

[0084] S02 foundation pit pretreatment: Complete the excavation of the foundation pit according to the design requirements. There is no need to construct a plain concrete cushion layer. Directly flatten and compact the bottom surface of the foundation pit to ensure that the flatness error of the bottom surface of the foundation pit is controlled within 1cm.

[0085] S03 base plate leveling component layout: After compaction and leveling, install the base plate leveling components 3 at the positions of the leveling holes 101 on the base plate 1, ensuring that each base plate 1 corresponds to 4 base plate leveling components 3, arranged in a rectangular array to match the size and specifications of the base plate 1.

[0086] S04 base plate hoisting and leveling: The prefabricated base plate 1 of the constant temperature workshop is hoisted into the foundation pit, aligned with the base plate leveling component 3, and slowly lowered to ensure precise alignment between the leveling hole 101 on the base plate 1 and the first screw 302 of the base plate leveling component 3. During the leveling stage, by rotating the first screw 302, the threaded engagement between the first screw 302 and the first base 301 drives the support ring 303 to rise and fall, thereby adjusting the levelness of the base plate 1. The flatness error of a single base plate 1 is controlled within 1mm, and the height difference between the top surfaces of adjacent base plates 1 is ≤0.5mm. After leveling is completed, the upper end of the leveling hole 101 is sealed with a sealing cap 305.

[0087] S05 Base Plate Splicing, Fixing, and Sealing: The splicing and fixing of adjacent base plates 1 are achieved using horizontal and vertical connecting components: the upright plates 204 of adjacent base plates 1 are fixed by U-shaped rods 4 to enhance the splicing strength. Horizontally adjacent base plates 1 are secured to the splicing gap by a first T-shaped strip 5, and a first fastening bolt 6 passes through the first T-shaped strip 5 and is threaded into the threaded hole 203 of the connecting plate 202 for locking. Vertically adjacent base plates 1 are secured to the splicing gap by a second T-shaped strip 7. Rotating the rotating rod 8 drives the double-headed stud 9 to rotate, causing the sliding tube 10 to extend and insert into the first tube 201 of the adjacent base plate 1, achieving positioning connection. After splicing, the splicing gap is sealed, debris and dust are cleaned from the gap, and low-temperature two-component polysulfide sealant is filled. After curing, carbon fiber cloth is laid for protection to ensure a tight seal and prevent water leakage.

[0088] S06 Horizontal Wall Panel Installation: The bottom horizontal wall panel 12 is installed at the corresponding position on the base plate 1, and a sealing strip 17 is used to achieve a tight fit with the base plate 1. A horizontal wall panel leveling assembly 18 is installed below the bottom horizontal wall panel 12. The second screw 1802 is inserted into the sleeve 1301 of the horizontal wall panel 12, and the height of the second screw 1802 is adjusted to ensure the horizontal wall panel 12 is vertical. Simultaneously, the U-shaped plate 1801 is fixed to the vertical plate 204 of the base plate 1 using a U-shaped rod 4. Adjacent horizontal wall panels 12 are joined together by a third T-shaped strip 15. A plug 14 is inserted into the sleeve 1301 of adjacent horizontal wall panels 12, and a second fastening bolt 16 passes through the third T-shaped strip 15 and is threaded into the second threaded tube 1302 to achieve a sealed connection. Adjacent vertical horizontal wall panels 12 on the same layer are sealed together by a wall panel connecting sealing strip 26.

[0089] An L-shaped stainless steel bracket is added between the inner wall of the bottom horizontal wall panel 12 and the bottom plate 1, and expansion bolts passing through the stainless steel bracket are used for fixed connection to increase the connection strength.

[0090] S07 Longitudinal Wall Panel Installation: Using the same installation method as the horizontal wall panel 12, the bottom vertical wall panel 19 is installed at the corresponding position on the base plate 1, and is sealed and fitted to the base plate 1 by the vertical wall panel sealing strip 23. A vertical wall panel leveling component 24 is installed below the bottom vertical wall panel 19. The height of the third screw 2402 is adjusted to ensure the verticality of the vertical wall panel 19. The support block 2404 abuts against the bottom surface of the vertical wall panel 19. The L-shaped insert 2405 is inserted into the second pipe 2001 and the first pipe 201 to enhance connection stability. Adjacent vertical wall panels 19 are sealed together by the fourth T-shaped strip 22, the straight insert 21, and the second fastening bolt 16. Adjacent vertical wall panels 19 in the same layer are sealed together by the wall panel connecting sealing strip 26.

[0091] An L-shaped stainless steel bracket is added between the inner wall of the bottom longitudinal wall panel 19 and the bottom plate 1, and expansion bolts passing through the stainless steel bracket are used for fixed connection to increase the connection strength.

[0092] S08 Corner Seal: At the corner where the transverse sidewall assembly and the longitudinal sidewall assembly intersect, a vertically installed corner sealing strip 25 is used to seal the joint, ensuring that there is no risk of leakage at the corner.

[0093] S09 Overall waterproof and airtight treatment: S091 Base Treatment: Clean the surfaces of the base plate 1, horizontal wall panels 12, and vertical wall panels 19, removing debris, dust, and oil stains. Dry the surface moisture using a hot air gun. Repair any cracks and holes on the panel surface to ensure the base layer is flat, dry, and has a moisture content ≤8%.

[0094] S092 Internal Protection Construction: Two coats of low-temperature cement-based penetrating crystalline waterproof coating are applied to the bottom and side walls of the pool, with a coating thickness of ≥1.5mm. The coating is then cured for ≥7 days under constant temperature conditions to form the first waterproof barrier.

[0095] S093 Node Waterproofing Reinforcement: For areas prone to leakage, such as the joints between adjacent precast slabs and the connection points between the side walls and the bottom, apply an additional layer of low-temperature polyurethane waterproof coating and lay an additional layer of waterproof membrane to ensure a tight seal.

[0096] S094 External Protection Construction: Low-temperature SBS modified bitumen waterproof membrane is laid on the bottom and side walls inside the pool. The overlap width of the membrane is ≥100mm, and the overlap is heat-fused welded. A polyurethane insulation protective layer is laid on the outside of the membrane, which has both insulation and protection functions.
