[0002] At present, many UHV substations and converter stations are being built or planned in China. UHV substations and converter stations include valve halls, longitudinal walls and multiple parallel fireproof, explosion-proof and waterproof walls (also called wing walls) built on one side of the longitudinal walls. Each transformer is surrounded by the longitudinal wall at the rear and the wing walls on the left and right sides. The wing walls on both sides can prevent fire and explosion and effectively protect the transformer.

[0003] Traditional wing walls are constructed by cast-in-place construction. When the seismic fortification intensity is less than 8 degrees, the wing wall and the valve hall building structure are subjected to stress as a whole. The height of the wing wall is very high, often reaching more than 20 meters. Cast-in-place concrete construction requires the construction of very high scaffolding, which is a high-formwork and high-risk construction method. Summary of the invention
