Beschreibung
Zusammenfassung:	A coupler interconnects adjacent sections of soil nails to extend the lengths of the nails. The coupler includes projections extending from the exterior surface of the coupler. The projections serve multiple purposes. One purpose is to center the soil nail within a drilled hole. Another purpose is to provide mixing for amounts of drilled material to remain within the hole, and/or evacuation of drilled material to be removed from the hole. Another purpose is to create a drilled hole with varying diameters in response to different geological layers encountered during drilling. The coupler may include a plurality of ports or openings formed in the body of the coupler enabling injected material such as grout to be further mixed by the rotating action of the coupler during use. The invention further includes a soil nail assembly and a method for installing a soil nail assembly including couplers with projections.
