The present device relates to a drill hole plug system, and more specifically, to a plug used to seal off rods or casings left in the ground after exploration diamond drilling. The present drill hole plug system is primarily comprised of a basket, connected to a basket adapter, which is in turn threaded onto a primary module. The basket initially locks the drill hole plug system into place, and the primary module is subsequently rotated, such that corresponding parts move forward and anchor the primary module into place within the casing. Afterwards, continued rotation of the primary module engenders a lead-in ring to compress a sealant, expanding said sealant within the drill hole plug system and effectively sealing it off. The drill hole plug system can also incorporate optional modular add-ons, such as a check valve and a shut-off valve. |
