The soil nailing is a corrective measure of the construction to treat the unstable natural slopes of the soil or as a construction technique that allows the safe over-accentuation of new or existing slopes of the soil. The technique involves the insertion of relatively thin reinforcing elements in the tilt, often general purpose reinforcing bars (reinforcing bars), although solid or hollow property bars are also available. The solid bars are usually installed in pre-drilled holes and then are grooved in place using a separate grout line, while the hollow bars can be perforated and sanded simultaneously by the use of a sacrificial drill bit and by pumping the grout down to measure which is advanced drilling. Kinetic methods have also been developed for firing relatively short bars on the slopes of the ground. The bars installed using drilling techniques are usually completely rejuntadas and installed with a slight slope downwards with bars installed in points regularly spaced through the face of the slope. On the surface, nail head plates of a rigid floor (often pneumatically applied, also known as projected concrete) or insulated can be used. Alternatively, a flexible reinforcing mesh may be maintained against the floor face below the head plates. Rabbit test wire mesh and environmental erosion control fabrics and can be used in conjunction with flexible mesh grid where environmental conditions dictate.
Soil nail components can also be used to stabilize existing containment walls or fill slopes (embankments and embankments); this is usually done as a corrective measure.
Since its first application using modern techniques in Versailles in 1972, nailing the ground is now a well-established technique throughout the world. One of the first national guide publications for soil nailing was produced in Japan in 1987. The US Highway Administration published the guide publications in 1996 and 2003.
