[0002] Power engineering, that is, the engineering related to the production, transmission, and distribution of electric energy. In a broad sense, it also includes the engineering of applying electricity as power and energy in various fields. In modern society, power engineering is a crucial field because electricity is the foundation to support various industrial, commercial, and daily life activities;

[0003] When power engineering transmits electric energy, it is necessary to erect high towers or poles for power engineering. The installation of both power high towers and poles requires civil engineering to pour the foundation base, and the bottom ends of the power high towers or poles are fixed through embedded parts. Currently, the adopted method of casting and fixing the embedded parts mostly uses manual auxiliary fixing to keep the embedded parts in the center position of the mold. However, it is difficult to ensure that the steel structure embedded parts are perpendicular to the casting area when using the manual auxiliary fixing method. When the steel structure embedded parts are offset, it will cause deviations between the foundation steel structure embedded parts and the holes of the power high tower and the pole, thus affecting the stability of the entire building or equipment. In view of this, for the above problems, there may already be technical means to solve them in the existing technology, but this case wants to provide an alternative or replacement technical solution.
