However, during the rebar embedding process, it is often difficult to clean the holes drilled with an electric drill. Dust, debris, and other impurities remaining in the holes can affect the bond between the rebar embedding adhesive and the rebar and concrete, making it impossible to guarantee the strength required for pull-out tests. Furthermore, the rebar embedding process is not uniform, making it prone to bubbles and voids, resulting in insufficient anchoring force for the rebar. Furthermore, the rebar embedding process is inefficient, making it difficult to meet the needs of large-scale civil engineering construction. Summary of the Invention
