DRILLING SYSTEM AND DRILLING METHOD

Japanese Patent JP2022139809

A

To provide a drilling system capable of automatically drilling in a concrete structure.SOLUTION: The drilling system includes: a drilling condition storage unit PCm1 that stores drilling conditions including the drilling position and the drilling depth of multiple holes to be drilled on a structure S; a drilling unit A that has a drifter 30 capable of moving vertically and horizontally; a drilling state detector SS that has a drilling position detection unit SSa and a drilling depth detection unit SSc; a control unit C that is configured to read the drilling conditions from the drilling condition storage unit PCm1 to control the drilling unit A to sequentially drill based on the drilling conditions, and as for a hole that the drifter 30 cannot drill to a depth according to the drilling conditions, control the drilling unit A to stop drilling and drill holes in next drilling sequence; and a drilling result storage unit PCm2 for storing drilling results. The drilling condition storage unit PCm1 stores drilling conditions that are updated to shift the drilling position of a hole and drill it only when there is a hole that cannot be drilled to a depth that meets the drilling conditions.SELECTED DRAWING: Figure 8
