[0002] The products are mainly used in power construction projects. The industry design uses cast-in-place C30 ordinary concrete molding process, which means that the concrete is poured and molded on the construction site, resulting in certain deficiencies in quality control. As the industry develops, the product design is gradually using precast cement concrete components. Factories use steel molds for assembly line production in workshops, which ensures product quality. However, the current situation is that the products are large in size and weight, resulting in high transportation and installation costs.

[0003] Currently, most clean energy substations, such as those for wind and solar power, are constructed in mountainous and hilly areas. This is significantly limited by the construction environment, technological conditions, and the technical skills of the construction personnel. Furthermore, the construction process is complex, costly, and results in inconsistent project quality. To address this situation, this project focuses on the development and research of reinforced concrete foundations for clean energy substations. Utilizing UHPC technology, prefabricated reinforced concrete products for power infrastructure construction, such as lightweight ring main units and transformer substation foundations, have been developed. These products are characterized by safe performance, lightweight and reliable structure, convenient construction, and high quality.

[0004] It is beneficial to save resources and energy, reduce construction pollution, and improve production efficiency and quality and safety levels. Due to the ultra-high performance concrete, lightweight and prefabricated design, the product quality is guaranteed, saving costs (concrete, steel bars, transportation and installation), and can adapt to various construction environment conditions (due to its lightweight and compact nature, it is not limited by construction environment conditions and can be constructed in deserts, mountains, hills and densely populated urban areas).

[0005] However, how to prepare the corresponding structure so as to facilitate rapid connection and fixation, and effectively ensure its stable use, is a difficult problem for those skilled in the art. Utility Model Content
