[0002] The decoking water tank in the delayed coking device of the petroleum chemical industry is used for storing the decoking water used in the production process, which has the characteristics of normal pressure and large volume. Most of the equipment is a steel circular vertical container. Because the equipment is circular in shape, and the adjacent structures are mostly rectangular, the space around the circular equipment cannot be effectively utilized, the actual land occupation is large, and there is waste. When the site area is limited, the height of the equipment often needs to be increased to realize its rated volume, resulting in thickening of the equipment wall and increase of the cost.

[0003] In the field of petroleum chemical construction engineering, rectangular reinforced concrete pools are also an effective means for storing normal pressure liquids. The rectangular reinforced concrete pool has the characteristics of regular shape, high space utilization, complex construction, long construction period. The construction site has many construction instruments and operation types, and the operation surface is crossed more, and the construction professional proficiency requirement is higher, and experienced construction personnel need to be implemented, otherwise the engineering quality may be reduced, the pool wall is easy to crack, the steel bars are exposed, etc. Further, the site construction formwork work load is large, the overall construction period is long, the site management difficulty is large, and unsafe hidden dangers may be produced. Site pouring concrete may bring more dust, solid waste, etc., causing high carbon emission and energy consumption, and also affecting the surrounding environment.

[0004] At present, most of the design schemes of prefabricated reinforced concrete pools simply apply the prefabricated scheme of conventional plates (shear walls, floors, parapets, etc.), without fully considering the structural characteristics and stress principle of the pool, the joint node position is not reasonably designed, the integrity after assembly is poor, and it often becomes a weak link of corrosion prevention, seepage prevention and stress. In addition, in some design schemes, the pool wall and the adjacent bottom plate are split into integrated components. Although such components can make the joint node position avoid the most unfavorable position of structural stress, there are still problems such as inconvenience in production, transportation and assembly.
