Wherein, the upright column can comprise a main upright column 1 and a secondary upright column 2; the cross beams may include primary beams 3 and secondary beams 4. After water is stored in the structure, the water pressure is higher and acts on the closing plate B and the partition plate C, the closing plate B and the partition plate C are connected with the upright posts and/or the cross beams on the space reticular framework A, so that the water pressure is transmitted to the space reticular framework A, and the space reticular framework A can completely resist the pressure of water on the closing plate B and the partition plate C through structural stress calculation; the tension force generated by the space reticular framework A on the closing plate B and the partition plate C and the pressure generated by water achieve stress balance. The space net-shaped frame A is a stressed structure of a water treatment structure and has the functions of supporting, fixing and drawing the closing plate B and the partition plate C.
The closed plate B is connected with the upright columns and/or the cross beams at the periphery outer side and the bottom of the space reticular framework A, the periphery outer side and the bottom of the space reticular framework A are sealed to form a sealed water tank body, and the sealed water tank body is ensured not to leak after being filled with water. The closed plate B and the partition plate C are respectively formed by connecting prefabricated closed plate units and partition plate units. The closed plate units, the partition plate units, the stand columns and the cross beams are all produced in a factory in a prefabricated mode to form standardized assembly parts.
In the actual production and construction, the closing plate B comprises a peripheral closing plate at the periphery of the closed space reticular framework and a bottom closing plate at the bottom of the closed space reticular framework, the peripheral closing plate is enclosed at the peripheral outer side of the closed space reticular framework A, the bottom closing plate is enclosed at the bottom of the closed space reticular framework A, and the bottom closing plate and the peripheral closing plate are connected together through a stand column and/or a cross beam or are mutually connected together to form an integrally sealed water pool body. The connection mode of the above components can be welding. The bottom closing plate can be a foundation bottom plate formed by pouring reinforced concrete, and the reinforced concrete foundation bottom plate is adopted to replace the bottom closing plate made of metal materials, so that metal manufacturing materials can be saved, and the construction cost is reduced. The bottom ends of the upright columns of the space reticular framework A can be pre-buried and fixed in a reinforced concrete foundation slab, so that the side face of the space reticular framework A can be connected with a prefabricated closed plate unit, the bottom of the manufactured surrounding closed plate is fixed on the foundation slab formed by pouring reinforced concrete, the surrounding closed plate is connected with the foundation slab to form a sealed water pool body, and two pool body construction schemes which can be selected according to actual conditions are formed. The partition plate C is arranged in the space mesh-shaped frame A, the partition plate units are connected with the stand columns and/or the cross beams in the space mesh-shaped frame A and are connected with the embedded part of the reinforced concrete foundation slab in a matched mode, the space inside the space mesh-shaped frame A is separated, and the sealed water tank body is separated into a plurality of water treatment functional areas, such as flocculation, sedimentation, filtration and other functional areas for water supply treatment or biochemical and sedimentation areas for sewage treatment and the like.
