Excuse me, what is primary embedment and secondary embedment in hydropower installation?

1, the first embedment is embedded during civil construction, as follows:

2. The secondary embedment refers to the things that still need to be put into the civil construction after the completion of the civil construction, and then put into the civil construction again by drilling holes, which is the secondary embedment, as follows:

Extended data

"Civil engineering" refers to civil engineering construction, including the construction of buildings, structures and engineering objects in houses, roads, railways, airports, bridges, water conservancy, ports, tunnels, water supply and drainage, protection and other facilities and places. Above ground, underground, land, water and underwater, including survey, design, construction and maintenance in the process of engineering construction.
