摘要： A method for attaching a plate to an interior of an underground excavation, the method comprising: placing a first surface of the plate adjacent to the interior of the excavation, the plate having at least one through a passageway disposed within the plate; forming a mounting hole within the excavation in alignment with the passageway; inserting a bolt from a second surface of the plate opposite the first surface through the passageway and into the mounting hole; the bolt having a dome portion being integrally attached to a washer portion, such that the dome portion extends in a convex manner away from the first side of the washer portion; and a driver connected to the dome portion; driving the bolt into through the passageway and the mounting hole by means of the driver; and securing the bolt to the mounting hole disposed within the excavation via an anchorage device, adhesive or grout.
