Abstract
A subsurface support is provided comprising a soil nail having an outer member and an inner member placed within the outer member. The soil nail includes features that maintain a uniform spaced relationship between the inner and outer members. The soil nail may be installed by drilling or launching through a launching device. The spaced relationship between the inner and outer members may be achieved by crimping the outer member, or by use of an insert installed between the inner and outer members. In other embodiments, the support is made of composite construction materials, and having a self-drilling capability. The soil nail has two primary members, namely, an outer threaded member, and an inner threaded member that is placed through the outer member The outer member is made from fiberglass, and a metallic drill bit is secured to a distal end of the soil nail. The inner member is preferably steel. A method is also provided to improve pull-out capacity of the soil nails by galvanizing the inner and outer members.
