Description

Technical Field

[0001] This invention belongs to the field of manufacturing technology of special environmental protection equipment for water pollution prevention and control in the energy-saving and environmental protection industry. Specifically, it relates to a water plant clear water pool pouring system. Background Technology

[0002] Water plants treat wastewater, purifying it into clean water for reuse to prevent environmental pollution. The clear water tank, as the core storage facility in the water treatment process, plays a crucial role in storing qualified clean water, regulating water supply, stabilizing water pressure, and ensuring continuous water supply. It is also a vital link connecting the end of the water treatment process to the city's water supply network. However, most water plants currently still use a single, integrated structure for their clear water tanks. This traditional design has revealed numerous drawbacks in actual operation, especially during chlorination disinfection and regular cleaning and maintenance. The most prominent problem is the need to completely empty the clear water tank, which can severely impact the city's normal water supply and even trigger regional water crises.

[0003] Chlorination disinfection of the clear water tank is a core step in ensuring the safety of drinking water and an indispensable routine operation in the daily operation of water plants. According to the relevant requirements of the "Standards for Drinking Water Quality," water leaving the plant must undergo strict disinfection treatment to ensure that harmful microorganisms, bacteria, and viruses are effectively killed and meet drinking water safety standards. Currently, the mainstream disinfection method in water plants is chlorination disinfection, including the addition of disinfectants such as liquid chlorine and sodium hypochlorite. The effectiveness of disinfection depends on thorough stirring and uniform mixing of the water in the clear water tank, as well as standardized contact reaction time. Because the existing clear water tank has a monolithic structure, with the water inside connected as a single unit without any partitions, to ensure that the disinfection effect covers the entire tank without dead ends or blind spots, all the clear water stored in the tank must be completely drained before disinfection. If the original water body is not drained, the residual water will dilute the added disinfectant, causing the disinfectant concentration to fail to meet the prescribed standards, resulting in incomplete disinfection and potential safety hazards to drinking water. At the same time, microorganisms and impurities that may remain in the original water body will also react ineffectively with the disinfectant, reducing disinfection efficiency and even producing harmful byproducts.

[0004] During long-term use, suspended solids, sediments, microbial slime, and other impurities gradually accumulate on the walls and bottom of clear water tanks. If these impurities accumulate over time, they not only reduce the effective water storage capacity of the tank, affecting its water supply regulation capacity, but also breed harmful microorganisms such as bacteria and algae, polluting the water and reducing drinking water quality. Therefore, according to relevant regulations, water plants must regularly clean, flush, and inspect clear water tanks, generally at least 1-2 times per year. Because existing clear water tanks have a monolithic structure without partitions, all clear water must be drained before manual cleaning, mechanical flushing, and tank inspection can be carried out. The entire cleaning and maintenance process typically takes 1-3 days, or even longer, depending on the size of the clear water tank and the degree of pollution. Summary of the Invention

[0005] This invention provides a water plant clear water tank pouring system, which divides the clear water tank into multiple parallel areas. These areas can be used simultaneously, and one or more areas can be disinfected or cleaned as needed to avoid regional water supply crises and other problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A water plant clear water tank pouring system includes multiple bottom formworks arranged side by side in a foundation pit, side formworks constructed between adjacent bottom formworks, the upper end of the side formworks being higher than the bottom formworks, and steel reinforcement cages tied between the bottom formworks and the bottom wall of the foundation pit, and between the side formworks and the bottom wall of the foundation pit, and an opening and closing side dam is provided at the upper end of adjacent side formworks, the opening and closing side dams being supported by a positioning support mechanism, the positioning support mechanism being detachably connected to the two adjacent side formworks.

[0007] A further technical solution involves installing multiple concave templates at intervals on the bottom template, with the diameter of each concave template gradually decreasing downwards in the vertical direction. Multiple channel forming templates are installed between the bottom template and the bottom wall of the foundation pit, and a vertical column is installed at the center of each concave template. The lower end of the vertical column passes through the corresponding channel forming template, and the poured concrete forms a guide zone through the concave area shaped by the concave template.

[0008] A further technical solution is that the concave template is an inverted trapezoidal structure, a first connecting edge is constructed at the outer edge of the concave template, and a second connecting edge adapted to the first connecting edge is constructed at the corresponding position of the bottom template and the concave template.

[0009] A further technical solution is that the concave template has a frustum-shaped structure, and multiple guide grooves are uniformly formed on the peripheral wall of the guide area.

[0010] A further technical solution is that the cross-section of the guiding channel shaped by the channel forming template is rectangular or circular, and multiple guiding channels are cast below each bottom template. Each of the guiding channels is connected to the main guiding pipe via a connecting branch pipe, and the main guiding pipe is connected to a vertical pipe equipped with a control valve.

[0011] A further technical solution is that the opening and closing side dam includes multiple opening and closing sub-dams arranged longitudinally along the clear water pool, each of the opening and closing sub-dams is constructed with a vertical shaft, the lower end of the vertical shaft passes through a reserved hole on the side template, and the opening and closing sub-dam is connected to a positioning support mechanism.

[0012] A further technical solution is that a transmission gear is coaxially connected to the upper end of each of the vertical shafts, and each vertical shaft is rotatably connected to a longitudinal beam. A longitudinal rack is provided on the longitudinal beam, and each transmission gear meshes with the longitudinal rack.

[0013] A further technical solution is that the positioning support mechanism includes a support part that is detachably connected to the side template, the lower end of each opening and closing dam abuts against the support part, and a multi-point clamping part is installed on the support part, the multi-point clamping part being detachably connected to each opening and closing dam.

[0014] A further technical solution is that the support part includes longitudinal support beams located on both sides of the lower end of the opening and closing dam, and each of the longitudinal support beams is connected to the corresponding side template via multiple transition seats spaced apart along its length.

[0015] A further technical solution is that the multi-point clamping part includes multiple mounting seats that are spaced apart on the longitudinal support beam along the length direction of the longitudinal support beam, and two adjusting screws are symmetrically threaded to each of the mounting seats. A clamping seat is installed at one end of the two adjusting screws that are close to each other, and the lower part of the opening and closing dam is clamped between the two clamping seats.

[0016] The present invention, by employing the above-described structure, achieves the following technological advancements compared to existing technologies: Traditional monolithic clear water tanks require complete drainage during chlorination disinfection or periodic cleaning, leading to water supply interruptions. This system, however, uses a combination of bottom and side panels to divide the tank into multiple independent, side-by-side areas. Combined with the upper, operable side dams, it allows for flexible switching between area isolation and connectivity. During disinfection, the target area's dam can be closed, draining only that area while other areas continue to store and supply water normally. This avoids incomplete disinfection due to disinfectant dilution and does not disrupt the city's normal water supply. Similarly, during cleaning and maintenance, individual or partial contaminated areas can be drained, while the remaining areas continue to perform their water storage and pressure stabilization functions, significantly reducing the risk of water supply interruptions and completely resolving the drawback of traditional designs that necessitate water outages for maintenance.

[0017] This invention features multiple bottom formworks arranged side-by-side, forming zoned pouring units in conjunction with side formworks. This allows for simultaneous pouring of multiple areas or phased construction, eliminating the need for a single, complete pour. This reduces the difficulty of erecting large formworks and the construction pressure of concrete pouring, thus improving construction safety. Reinforcing steel frames are tied between the bottom and side formworks and the bottom wall of the foundation pit, ensuring that the poured clear water tank (including the bottom and partitioned walls) forms a unified load-bearing structure. This enhances impermeability, compressive strength, and durability, meeting the load requirements of long-term water storage in clear water tanks and reducing potential problems such as leakage and cracking. The positioning support mechanism is detachably connected to the side formwork, allowing for easy removal of the formwork and support components after pouring. This enables formwork reuse, reduces construction costs, and minimizes damage to the formed tank structure.

[0018] This invention allows for independent cleaning, maintenance, and disinfection of each zone without requiring a complete shutdown, thus shortening single maintenance time. The sluice gate allows for flexible adjustment of the zone connectivity, adapting not only to maintenance needs but also to adjusting water distribution in each zone based on changes in urban water supply (such as peak water usage and low-peak storage), enhancing the water supply regulation capacity of the clear water tank and stabilizing water pressure. For large water plants, the number of zones can be expanded by increasing the number of bottom and side formwork, improving the precision of water supply regulation. The upper part of the side formwork is higher than the bottom formwork, creating a height difference between the zones. Combined with the sealing effect of the sluice gate, independent water level control can be achieved in each zone, meeting differentiated water storage needs under special operating conditions (such as emergency water reserves and temporary storage of different water qualities).

[0019] In summary, the core value of this system lies in its combination of zoned design, flexible opening and closing, and a stable structure. This not only resolves the contradiction between the operation and maintenance of traditional clear water tanks and water supply, but also takes into account construction feasibility, structural reliability, and operational economy, providing an efficient and safe solution for the construction and operation of clear water tanks in water plants.

Detailed Implementation

[0023] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0024] This invention discloses a water plant clear water tank pouring system, such as... Figures 1-12 As shown, the structure includes multiple bottom formworks 1 arranged side by side within the foundation pit. Side formworks 12 are constructed between adjacent bottom formworks 1, with the upper ends of the side formworks 12 higher than the bottom formworks 1. Reinforcing steel frames are tied between the bottom formworks 1 and the bottom wall of the foundation pit, and between the side formworks 12 and the bottom wall of the foundation pit. Openable side dams are provided at the upper ends of adjacent side formworks 12, supported by a positioning support mechanism. The positioning support mechanism is detachably connected to the two adjacent side formworks 12.

[0025] Traditional monolithic clear water tanks require complete drainage during chlorination disinfection or periodic cleaning, leading to water supply interruptions. This system, however, uses a combination of multiple bottom and side panels (12) to divide the clear water tank into several independent, parallel areas. Combined with the upper, openable side dams, it allows for flexible switching between area isolation and connectivity. During disinfection, the target area's dam can be closed, draining only that area while other areas continue to store and supply water normally. This avoids incomplete disinfection due to disinfectant dilution and does not disrupt the city's normal water supply. Similarly, during cleaning and maintenance, individual or partial contaminated areas can be drained, while the remaining areas continue to perform their water storage and pressure stabilization functions, significantly reducing the risk of water supply interruptions and completely resolving the drawback of traditional designs that necessitate water outages for maintenance.

[0026] This invention features multiple bottom formwork 1s arranged side-by-side, forming zoned pouring units in conjunction with side formwork 12s. This allows for simultaneous pouring of multiple areas or phased construction, eliminating the need for a single, complete pour, reducing the difficulty of erecting large formwork and the construction pressure of concrete pouring, and improving construction safety. Reinforcing steel frames are tied between the bottom formwork 1s, side formwork 12s, and the bottom wall of the foundation pit, ensuring that the poured clear water tank body (including the tank bottom and partitioned walls) forms an integral load-bearing structure. This enhances impermeability, compressive strength, and durability, meeting the load requirements of long-term water storage in clear water tanks and reducing potential problems such as leakage and cracking. The positioning support mechanism is detachably connected to the side formwork 12, allowing for easy removal of the formwork and support components after pouring, enabling formwork reuse, reducing construction costs, and minimizing damage to the formed tank structure.

[0027] This invention allows for individual cleaning, maintenance, and disinfection of each zone without requiring a complete shutdown, thus shortening single maintenance time. The sluice gate allows for flexible adjustment of the zone connectivity, adapting not only to maintenance needs but also to adjusting water distribution in each zone based on changes in urban water supply (such as peak water usage and low-peak storage), enhancing the water supply regulation capacity of the clear water tank and stabilizing water pressure. For large water plants, the number of zones can be expanded by increasing the number of bottom formwork 1 and side formwork 12, improving the precision of water supply regulation. The upper end of the side formwork 12 is higher than the bottom formwork 1, creating a height difference between the zones. Combined with the sealing effect of the sluice gate, independent water level control can be achieved in each zone, meeting differentiated water storage needs under special operating conditions (such as emergency water reserves and temporary storage of different water qualities).

[0028] In summary, the core value of this system lies in its combination of zoned design, flexible opening and closing, and a stable structure. This not only resolves the contradiction between the operation and maintenance of traditional clear water tanks and water supply, but also takes into account construction feasibility, structural reliability, and operational economy, providing an efficient and safe solution for the construction and operation of clear water tanks in water plants.

[0029] As a preferred embodiment of the present invention, such as Figures 3-8As shown, multiple concave templates 2 are installed at intervals on the bottom template 1. The diameter of each concave template 2 gradually decreases downwards in the vertical direction. Multiple channel forming templates 15 are installed between the bottom template 1 and the bottom wall of the foundation pit. A vertical column 5 is installed at the center of each concave template 2, and the lower end of the vertical column 5 passes through the corresponding channel forming template 15. The poured concrete forms a guide zone 6 through the concave area shaped by the concave template 2. Multiple grouting pipes 16 are installed at intervals on the bottom template 1 and the top of the side template 12. The concave template 2 is an inverted trapezoidal structure. A first connecting edge 4 is constructed at the outer edge of the concave template 2, and a second connecting edge 3 adapted to the first connecting edge 4 is constructed at the corresponding position of the bottom template 1 and the concave template 2. The concave template 2 can also be a frustum-shaped structure, with multiple guide grooves 7 evenly formed on the peripheral wall of the guide zone 6. After removing the vertical column 5 at the center of the guide zone 6, a connecting channel 8 is formed. The cross-section of the guiding channel 10, shaped by the channel forming template 15, is rectangular or circular, and the guiding channel 10 is connected to the connecting channel 8. Multiple guiding channels 10 are poured below each bottom template 1, and each guiding channel 10 is connected to the connecting main pipe 27 via a connecting branch pipe 26. The connecting main pipe 27 is connected to a vertical pipe 28 equipped with a control valve. After pouring the bottom template 1 and side templates 12, a concrete foundation 9 is formed at the bottom of the bottom template 1, and a dividing dam 11 is formed at the bottom of the side templates 12. The dividing dam 11 is integrally formed with the concrete foundation 9, and both the diversion zone 6 and the guiding channel 10 are formed on the concrete foundation 9. The lower end of the opening and closing side dam is installed on the dividing dam 11.

[0030] In this embodiment, the concave template 2 forms a flow guiding zone 6, which, together with the uniform flow guiding groove 7 on the periphery of the frustum-shaped structure, guides the water to form an orderly flow within the zone, avoiding the formation of local stagnant water areas. Especially during chlorination disinfection, the flow guiding structure promotes thorough mixing of the disinfectant and the water, ensuring disinfection without dead corners and solving the problems of uneven disinfectant diffusion and incomplete disinfection in traditional integrated clear water tanks. The design of the inverted trapezoidal or frustum-shaped flow guiding zone 6 utilizes the downward tapering structure to accelerate water circulation, reduce suspended solids deposition, and lower the risk of water pollution. The connecting channel 8 formed after removing the vertical column 5 at the center of the flow guiding zone 6 is interconnected with the guiding channel 10 (rectangular or circular cross-section) formed by the channel forming template 15, and then forms a complete water distribution network through the connecting branch pipe 26, the connecting main pipe 27, and the vertical pipe 28 with a control valve. On the one hand, it enables flexible scheduling of water bodies in each zone. When a zone needs to be disinfected or cleaned, the corresponding area's connecting channel 10 can be closed by controlling the valve, without affecting the normal water supply of other zones, thus completely avoiding the water supply interruption problem caused by the overall emptying of the traditional clear water tank. On the other hand, the control valve of the vertical pipe 28 can accurately adjust the water supply of each zone, adapt to the water demand of the city at different times, and stabilize the water pressure.

[0031] The concave template 2 is connected to the bottom template 1 via the first connecting edge 4 and the second connecting edge 3, achieving precise positioning and firm fixation, thus preventing structural deformation caused by template displacement during pouring. The dividing bottom dam 11 is integrally formed with the concrete foundation 9, and the lower end of the opening and closing side dam is installed on the dividing bottom dam 11, forming a stable support system of foundation, bottom dam, and side dam, which improves the load-bearing capacity and impermeability of the overall structure of the clear water tank and extends its service life. The channel forming template 15 is pre-set with a rectangular or circular cross-section of the guide channel 10 structure, eliminating the need for on-site temporary shaping and reducing construction errors. Both the concave template 2 and the channel forming template 15 are modular designs, which can be flexibly combined and installed according to the volume and partition size of the clear water tank, adapting to the construction needs of water plants of different sizes, while simplifying the construction process and shortening the pouring cycle.

[0032] In this embodiment, the through structure formed by the guide channel 7 and the connecting channel 8 in the guide zone 6 can guide the water flow to flush the bottom of the pool, reducing the accumulation of suspended matter in the guide zone 6 and around the connecting channel 8. When cleaning is required, the water flow speed can be adjusted through the control valve of the vertical pipe 28, and self-cleaning can be achieved by utilizing the impact force of the water flow. With the partition isolation design, only a single area needs to be shut off for cleaning, without the need for overall drainage, thus shortening the cleaning time and reducing labor and machinery costs. The modular template design (the concave template 2 and the channel forming template 15 can be disassembled and replaced) allows subsequent maintenance or modification of the guide zone 6 and the connecting channel 10 without damaging the overall concrete structure. The control valves of the connecting main pipe 27 and the vertical pipe 28 independently control the channels of each partition. When maintaining a certain connecting channel 10, the corresponding control valve can be closed without affecting the normal water supply of other partitions, ensuring the continuity of water supply. The dividing dam 11 is integrally cast with the concrete foundation 9. The diversion zone 6 and the guiding channel 10 are both formed on the concrete foundation 9, avoiding the leakage problems of traditional spliced ​​structures, improving the waterproof performance of the clear water tank, and ensuring that the water quality is not affected by external soil pollutants. The diversion zone 6 and the guiding channel 10 are both integrated inside the concrete foundation 9, without occupying additional effective water storage space in the clear water tank. While realizing the zoning function, the water storage volume is maximized. The connecting branch pipe 26 and the connecting main pipe 27 are hidden under the concrete foundation 9, avoiding the problems of damage or occupation of operating space caused by exposed pipes, and optimizing the internal layout of the clear water tank.

[0033] As a preferred embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 12As shown, the opening and closing side dam includes multiple opening and closing sub-dams 13 arranged longitudinally along the clear water pool. Each opening and closing sub-dam 13 is constructed with a vertical shaft 18. The lower end of the vertical shaft 18 passes through a reserved hole 17 on the side template 12, and the opening and closing sub-dam 13 is connected to a positioning support mechanism. A transmission gear 19 is coaxially connected to the upper end of each vertical shaft 18. Each vertical shaft 18 is rotatably connected to a longitudinal beam 21. A longitudinal rack 20 is provided on the longitudinal beam 21, and each transmission gear 19 meshes with the longitudinal rack 20.

[0034] This embodiment employs a structure of multiple openable / closed dams 13 spaced longitudinally along the clear water tank. The opening and closing status of one or more of these dams 13 can be controlled individually according to operational needs. For example, when a zone requires chlorination disinfection, cleaning, or maintenance, only the corresponding openable / closed dam 13 needs to be closed, achieving physical isolation between that zone and other normal water supply zones. This eliminates the need for the entire clear water tank to be emptied, completely resolving the industry pain point of mandatory water outages during traditional integrated clear water tank operations, ensuring continuous and stable urban water supply, and preventing regional water supply crises. By opening and closing different combinations of openable / closed dams 13, the number and volume of effective water storage zones in the clear water tank can be flexibly adjusted to adapt to changes in water load during different times of the day (such as morning peak hours and nighttime off-peak hours). Simultaneously, when a zone experiences water quality abnormalities, equipment malfunctions, or other emergencies, the corresponding openable / closed dam 13 can be quickly closed to isolate the faulty area without affecting the normal water supply to other zones, thus improving the emergency response capability of the water supply system.

[0035] In this embodiment, the upper end of the vertical shaft 18 of each opening and closing dam 13 is coaxially connected to a transmission gear 19, which meshes with the longitudinal rack 20 on the longitudinal beam 21, forming a unified transmission system. By driving the longitudinal rack 20 to move along the longitudinal beam 21, all transmission gears 19 can be driven to rotate synchronously, thereby realizing the synchronous opening and closing of multiple opening and closing dams 13, ensuring the sealing and consistency of the partition isolation, and avoiding water crossflow and isolation failure caused by asynchronous opening and closing of individual dams; at the same time, the meshing transmission of the gear and rack has a clear transmission ratio, and the opening angle of the opening and closing dam 13 can be precisely adjusted by controlling the moving distance of the longitudinal rack 20, realizing fine control of water flow and adapting to the water flow adjustment needs under different operating scenarios (such as water stagnation during disinfection and full-load flow during normal water supply). Compared to traditional decentralized manual opening and closing structures, this linkage design only requires a single drive source (such as a motor driving the longitudinal rack 20) ​​to control all opening and closing dams 13, greatly reducing the intensity and complexity of operation and reducing manual input; it is especially suitable for large clear water pools, avoiding the tedious process of operating one by one and improving work efficiency (such as disinfection and isolation of zoning before cleaning can be completed in a short time).

[0036] As a preferred embodiment of the present invention, such as Figures 9-11As shown, the positioning support mechanism includes a support part detachably connected to the side template 12. The lower end of each opening / closing dam 13 abuts against the support part. A multi-point clamping part is installed on the support part, and the multi-point clamping part is detachably connected to each opening / closing dam 13. The support part includes longitudinal support beams 14 respectively disposed on both sides of the lower end of the opening / closing dam 13. Each longitudinal support beam 14 is connected to the corresponding side template 12 via multiple adapter seats 22 spaced apart along its length. The multi-point clamping part includes multiple mounting seats 23 spaced apart along the length of the longitudinal support beams 14. Two adjusting screws 24 are symmetrically threaded onto each mounting seat 23. A clamping seat 25 is installed at the end of the two adjusting screws 24 that are close to each other, and the lower part of the opening / closing dam 13 is clamped between the two clamping seats 25.

[0037] In this embodiment, the support section provides a stable bottom support reference for the opening and closing dam 13 through longitudinal support beams 14 located on both sides of the lower end of the opening and closing dam 13, ensuring that the lower end of the opening and closing dam 13 is vertically aligned with the reserved holes 17 of the side template 12. The multi-point clamping section uses mounting seats 23 spaced along the longitudinal support beams 14, in conjunction with symmetrically arranged adjusting screws 24 and clamping seats 25, to clamp and fix the opening and closing dam 13 from multiple points on both sides. During installation, the spacing of the clamping seats 25 can be finely adjusted by rotating the adjusting screws 24 to accurately correct the verticality, horizontal spacing, and fit with the side template 12 of the opening and closing dam 13, avoiding excessive gaps between the vertical axis 18 and the reserved holes 17 caused by tilting or misalignment of the opening and closing dam 13, or sealing gaps between the opening and closing dams 13. This ensures the sealing of subsequent partition isolation from the construction source and solves the water flow problem caused by positioning errors in traditional installation. The multi-point clamping section employs multiple mounting seats 23 evenly distributed along the longitudinal direction to achieve symmetrical and uniform clamping of the lower part of each opening and closing dam 13, avoiding uneven force and local deformation of the opening and closing dam 13 caused by a single clamping point. At the same time, the symmetrically threaded adjusting screw 24 can achieve precise control of the clamping force, ensuring that the installation posture of each opening and closing dam 13 is consistent, laying the foundation for the precise meshing of the subsequent transmission gear 19 and longitudinal rack 20, and avoiding problems such as transmission jamming and synchronous opening and closing failure caused by the installation angle deviation of the opening and closing dam 13.

[0038] In this embodiment, the longitudinal support beam 14 of the support section is detachably connected to the side formwork 12 through multiple adapter seats 22, forming a stable support frame of side formwork 12, adapter seats 22, and longitudinal support beam 14, providing bottom load-bearing support for the opening and closing dam 13. The multi-point clamping part clamps and fixes the opening and closing dam 13 from both sides, forming a double fixing structure of bottom support and clamping, which effectively resists external force collisions, vibrations and other interferences during the installation process (such as vertical shaft 18 assembly, transmission component debugging, and formwork verification before concrete pouring), prevents the opening and closing dam 13 from tilting or shifting, ensures the safety of construction personnel, and avoids collision damage between the opening and closing dam 13 and the reserved hole 17, and between the transmission gear 19 and the longitudinal rack 20. The longitudinal support beam 14 extends along the length of the opening and closing dam 13, and together with multiple spaced transition seats 22 and assembly seats 23, it distributes the weight of the opening and closing dam 13 and the external construction force to the side formwork 12 and the foundation pit support structure, avoiding the deformation of the side formwork 12 or the failure of the support mechanism due to excessive local support point stress. It is especially suitable for the installation requirements of long-span opening and closing side dams in large clear water pools, and improves the structural stability during construction.

[0039] All components of this example of a positioning support mechanism are designed to be detachable: the longitudinal support beam 14 is bolted to the side formwork 12 via the adapter 22; the assembly seat 23 is detachably fixed to the longitudinal support beam 14; and the adjusting screw 24 and the clamping seat 25 are detachable assemblies. During construction, the longitudinal support beam 14 can be fixed first, then the opening and closing dams 13 can be positioned and clamped one by one, and finally the transmission components can be assembled. The process is clear and can be carried out in parallel. After installation, the clamping seat 25, adjusting screw 24, assembly seat 23, and longitudinal support beam 14 can be removed sequentially without damaging the side formwork 12 or the opening and closing dam 13 structure, without affecting subsequent concrete pouring or the overall structural integrity of the clear water tank, significantly shortening the installation and dismantling cycle and improving construction efficiency. The longitudinal support beam 14, adapter 22, assembly seat 23, and other components are all standardized designs. The length of the longitudinal support beam 14 and the spacing between the adapter 22 and the assembly seat 23 can be flexibly adjusted according to the length of the clear water tank and the number and size of the opening and closing dams 13 to adapt to the construction needs of clear water tanks of different sizes. Meanwhile, each individual opening / closing dam 13 can be independently positioned and fixed via its corresponding clamping point, facilitating batch installation and debugging, reducing the difficulty of overall installation of large clear water tanks, and improving construction flexibility. After the positioning support mechanism is completely removed, only the opening / closing side dam and transmission components (vertical shaft 18, transmission gear 19, longitudinal rack 20, etc.) remain on the upper part of the clear water tank, with no residual support components occupying space, avoiding mechanical interference of traditional fixed support structures on the rotation of the opening / closing dam 13. The opening / closing dam 13 can rotate freely around the vertical shaft 18 to open / close, ensuring the synchronization and smoothness of gear and rack drive, and improving the response speed of zone control. After removal, there are no extra protrusions or gaps in the clear water tank, and no support components obstruct the opening / closing dam 13, reducing the adhesion and deposition of suspended solids and microorganisms; during subsequent daily cleaning, the opening / closing dam 13 and its surrounding area can be directly rinsed, ensuring thorough cleaning without dead corners, reducing the risk of bacterial growth, and meeting the cleanliness requirements of the "Standards for Drinking Water Quality" for clear water tanks.

[0040] In this embodiment, the longitudinal support beam 14, adapter seat 22, assembly seat 23, adjusting screw 24, etc. of the positioning support mechanism are all standardized metal components. After disassembly, they can be recycled and reused for other clear water tank construction or for subsequent maintenance and replacement of the opening and closing dam 13 in the same clear water tank. This eliminates the need for one-time consumption, reducing construction material costs and conforming to the concept of green construction. When subsequent maintenance or replacement of components such as the opening and closing dam 13 and vertical shaft 18 is required, the positioning support mechanism can be reassembled to quickly provide a stable positioning support benchmark for the opening and closing dam 13 without the need for additional temporary support, simplifying the maintenance process and shortening maintenance time. At the same time, the modular and detachable design allows damaged components (such as adjusting screw 24 and clamping seat 25) to be replaced individually without replacing the entire support mechanism, further reducing maintenance costs. The positioning support mechanism only functions for the installation and positioning of the opening and closing dam 13, and does not directly contact the concrete pouring area. After removal, it will not leave any residual structure on the concrete foundation 9 or the dividing dam 11, and will not affect the integral molding quality of the dividing dam 11 and the concrete foundation 9, thus ensuring the impermeability and load-bearing capacity of the overall structure of the clear water pool. The support part is detachably connected to the side formwork 12 through the adapter 22, without the need to modify the original bottom formwork 1 and side formwork 12 structure. It is compatible with the overall construction process of the clear water pool formwork pouring system and can be carried out in parallel with processes such as rebar binding and grouting pipe 16 installation, avoiding conflicts in construction procedures and improving overall construction efficiency.
