[0002] In aquaculture, fish have different requirements for the water temperature of the pool. In some regions, the aquaculture ponds need to be designed with a thermal insulation system. At the same time, an aquaculture base usually has various forms of pond structures and simple decoration methods, and has high requirements for the construction quality of the main structure. The existing pond walls usually adopt formwork pouring and fix thermal insulation materials such as thermal insulation boards on the outer wall of the wall. However, it is inevitable that there will be splicing gaps between the thermal insulation boards of the pond wall, resulting in poor thermal insulation effect. Especially for the thermal insulation boards located on the inner wall, due to long-term contact with water, there are also problems of easy moisture absorption and easy falling off.
[0003] At the same time, the pouring of the pond wall requires the erection of a traditional formwork reinforcement system. For aquaculture ponds with various forms, the formwork construction cost is high, the difficulty is great, and the input of turnover materials is large; and after pouring, there is also a large amount of work for the thermal insulation boards on the pond wall decoration. For aquaculture ponds with various forms, not only the decoration difficulty is greater, but also more thermal insulation board splicing gaps will be generated, further reducing the thermal insulation effect.
[0004] Based on this, it is necessary to study an EPS module sandwich thermal insulation concrete pool structure. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] The following further describes the present utility model in detail in conjunction with the drawings and specific embodiments:
[0030] This embodiment aims to provide an EPS module sandwich heat-insulated concrete pool structure, which is mainly used for the construction of aquaculture ponds, aiming to solve the problems of poor heat insulation and long construction period of the existing aquaculture pond wall 2.
[0031] An EPS module sandwich heat-insulated concrete pool structure, as Figure 1 , includes a bottom plate 1 and a pond wall 2. The bottom plate 1 is obtained by casting. Before casting, steel bars need to be tied. When tying the steel bars, the intersection points of the two rows close to the periphery are tied at each point, and the intersection points in the middle part can be tied at intervals and staggered. For the steel bars under two-way stress, all the intersection points of the steel bars must be tied. When tying the steel bars, the pond wall steel bars 3 also need to be tied. One point is positioned on the extension line at each end of each side of the pond wall 2, and the pond wall steel bars 3 are installed by pulling a straight line, so that a plurality of vertical pond wall steel bars 3 are pre-buried at intervals on the bottom plate 1, and the pond wall steel bars 3 extend vertically upward from the bottom plate 1.
[0032] The pool wall 2 includes an EPS module 4 and a concrete layer 5. The EPS module 4 includes an inner plate 401, an outer plate 402 and rib plates 403. The inner plate 401 and the outer plate 402 are arranged in parallel at intervals, and the rib plates 403 are connected between the inner plate 401 and the outer plate 402. The EPS module 4 is a building wall module with a flame-retardant polystyrene foam plastic module as a formwork and a thermal insulation layer. Concrete can be poured in the middle, and plastering can be done on the surface. In practical applications, various-sized aquaculture ponds can be decomposed into EPS insulation modules with simple structures after in-depth design. Structures for mutual splicing and connection are provided between the modules. After being processed in a factory and transported to the site, they can be directly assembled, meeting the requirements of engineering assembly. The specific structure of the EPS module 4 is prior art and will not be elaborated here.
[0033] Such as Figure 1 and Figure 2 , the EPS modules 4 are continuously spliced and arranged in the up-down and left-right directions to form the pool wall 2, and a pouring chamber 404 is formed between the inner plate 401 and the outer plate 402. The pool wall steel bars 3 are distributed in the pouring chamber 404, and the pool wall steel bars 3 are correspondingly arranged between adjacent two rib plates 403. After the EPS modules 4 are installed, wooden beams are used to reinforce the middle and corners of the pool wall 2. The spacing of the wooden beams is fixed and not greater than 2 m. After reinforcement, a plumb bob is used to check the perpendicularity of the pool wall 2, and a line is pulled along the axis to check whether the pool wall 2 is displaced, and deviation is corrected in time.
[0034] After the EPS module 4 is supported and reinforced, slope finding needs to be carried out at the bottom of the pool; such as Figure 1 , mortar corner guards 6 are continuously arranged between the inner plate 401 and the bottom plate 1 and between the outer plate 402 and the bottom plate 1 along the pool wall 2. The mortar corner guards 6 are used to seal the splicing gap between the pool wall 2 and the bottom plate 1 to avoid slurry leakage during pouring, and can also enhance the sealing performance of the aquaculture pond and further enhance the leak prevention performance during use.
[0035] Furthermore, in order to facilitate drainage, a slope-forming layer 9 is provided on the bottom plate 1. The highest point of the slope-forming layer 9 covers the mortar corner guard 6, and a drain opening 10 is reserved on the bottom plate 1. The lowest point of the slope-forming layer 9 is located at the drain opening 10.
[0036] After the construction of the mortar corner guard 6 and the slope-forming layer 9 is completed, concrete is poured in layers in the pouring chamber 404 to form the concrete layer 5. The concrete preferably uses fine aggregate concrete with a relatively large slump (180±20) and good fluidity. The cement uses medium-low heat Portland 42.5 cement or slag Portland cement with a relatively low heat of hydration. The admixture should use an admixture with good compatibility with the cement, a water reduction rate of 20% - 25%, a chloride ion content of less than 0.03%, an alkali content of less than 0.5%, and a pressure bleeding ratio of less than 50% (such as high-performance water-reducing agents with a retarding effect like FS-I, etc.).
[0037] After the concrete of the pool body has reached the design strength requirements, the pool will be cleaned, the reserved holes, embedded pipe openings, water inlets and outlets will be temporarily blocked, and a water storage test will be carried out.
[0038] After the water storage test is passed, if Figure 1 , a continuous waterproof mortar surface layer 11 is set on the exposed surface of the bottom plate 1, the exposed surface of the pool wall 2 and the exposed surface of the slope layer 9. The waterproof mortar surface layer 11 uses polymer waterproof and crack-resistant mortar. The mixing must be carried out on-site with a mortar mixer or a portable electric drill with mixing teeth. Manual mixing cannot be used. Plastering is done two to three times, and the thickness of each layer of plastering is 2 to 3mm. After the first layer of plastering is applied, the glass fiber mesh is pressed in, and the second layer of plastering is applied after it is dried and formed into a film. The surface of the last layer of plastering should be compacted and smoothed. The mortar consumption per square meter is about 2.0㎏ / ㎜.
[0039] In order to further improve the water-proof property and aesthetics, a waterproof paint layer 12 is continuously applied on the waterproof mortar surface layer 11, using aquaculture oil-based special paint.
[0040] Furthermore, in order to optimize the water-proof performance, a water-stop steel plate 7 is also included, such as Figure 1 The water-stop steel plate 7 is embedded in the bottom plate 1 and arranged continuously along the pool wall 2. The upper part of the water-stop steel plate 7 extends vertically upward from the bottom plate 1 and is inserted into the casting chamber 404. The water-stop steel plate 7 is L-shaped and is fixed to the steel structure of the bottom plate 1 before casting. After the EPS formwork is installed, the outer surface of the water-stop steel plate 7 fits the inner surface of the inner plate 401, so that the water-stop steel plate 7 can be used to limit the position, so as to facilitate the rapid installation of the EPS formwork.
[0041] Furthermore, considering that the waterproof steel plate 7 is thin and located at the side of the casting chamber 404, and the pool wall reinforcement 3 is located in the middle of the casting chamber 404, the installation of the waterproof steel plate 7 and the pool wall reinforcement 3 needs to be positioned separately, which is more complicated. In order to facilitate positioning and installation, a limit card 8 is also included, such as Figure 3 The limit card 8 is an integrally bent "J"-shaped structure. The limit card 8 is located between the pool wall reinforcement 3 and the water-stop steel plate 7. Both ends of the limit card 8 are fixed on the inner surface of the water-stop steel plate 7. The middle part of the limit card 8, which is away from the water-stop steel plate 7, has a groove adapted to the pool wall reinforcement 3. The pool wall reinforcement 3 is adapted to abut and bind in the groove. In this embodiment, the groove is an inferior arc groove, while in other embodiments, the groove can also be made into a superior arc groove, and the limit card 8 is fixed to the pool wall steel plate by its own elasticity. The middle part of the limit card 8 is away from the water-stop steel plate 7 and maintains a gap, which can reduce the impact on pouring and ensure the stable connection between the pool wall 2 and the bottom plate 1 after pouring.
