Concrete construction method for main variable cavern structure

The invention discloses a concrete construction method of a main variable cavern structure. A main variable cavern is divided into regions, zoning and time-sharing construction is carried out, and in the construction process, an embedded part project adopts the mode of compiling information cards and matching the information cards of embedded parts with field information cards, so that the error rate of manual verification is reduced; the embedded parts enter the site in a time-sharing and zoning mode according to compiled information, so that the construction logic is clear, in the main variable cavern area construction of a large number of embedded parts, the construction efficiency is greatly improved, and the probability of neglected burying of the embedded parts is reduced; the mode of zoning construction is adopted in formwork engineering, and anchor bars on site structural surfaces are fully utilized for fixing, so that the structural stability is enhanced, and the formwork erecting cost is reduced; an
