The invention relates to an embedding method of multi-functional central target plates, belonging to the technical field of measurement control. The embedding method of the multi-functional central target plates comprises the following process steps of: checking a civil engineering datum line; selecting the embedding positions and the number of the multi-functional central target plates; scribing the embedding positions; drilling by using a hydraulic drill; embedding bases of the multi-functional central target plates; accurately positioning adjustable datum disks; carrying out spot welding fixation on the adjustable datum disks; carrying out secondary checking; and embedding a datum point protection box. The embedding method has the advantages of being used for directing how to control the embedding accuracy of the multi-functional central target plates, playing an active directive role in how to apply the multi-functional central target plates by programming the embedding method of the multi-functional central target plates, thoroughly solving various problems appearing in the previous embedding process, such as the problem that the adjustable datum disks exceed sliding tables of the bases when adjusted, the problem that the multi-functional central target plates are more higher than the horizon after embedded, and other phenomena, and additionally more greatly increasing the embedding accuracy and the embedding efficiency of the multi-functional central target plates, thereby providing more reliable accuracy guarantee for subsequential application.
