Problems solved by technology

Judging from the currently available public information, there are only practical introductory texts, and no specific technical details are involved.
However, domestic research on this technology started relatively late, mainly focusing on conceptual research and theoretical description, and there is no in-depth elaboration on how to construct, implement and apply engineering
In summary, none of the existing materials can solve the construction and engineering implementation problems of this technology well. The present invention proposes a construction method and provides the engineering implementation process
