Self drilling anchor for soil nails

Soil nail wall is a gravity composite soil structure in which an excavated slope or vertical cut is internally reinforced through the placement of closely spaced linear reinforcing elements. Reinforcing elements like ground screws are installed by placing them into the existing soil slope or new excavation. This adds strengthened soil nail slope stability for long-term earth retention.

Soil nailing is an efficient, effective and economical method of soil reinforcement. The reinforcement is installed into the slope face of in-situ ground, whether natural soil or an existing fill, stabilising such material. Soil nailing can be used to stabilise, existing structures such as unstable slopes, embankments and retaining walls. The use of soil nails can be adopted for the stabilisation of cuttings and coastal and quarried cliffs. The construction of new steep slopes for widening of infrastructure routes, new developments and new retaining walls, has seen an increase in the use of soil nailing. This method of soil reinforcement can be used for both permanent and temporary applications.

The self drilling anchor(SDA) system offers self-drilling soil nails where the central hollow threaded reinforcement bar acts as both final reinforcement in the completed anchor and as the drill rod during installation. The self drilling anchor(SDA) system is installed with sacrificial drill bits under a grout flush. In granular deposits in particular, the impregnation of grout into the surrounding ground significantly enhances the geotechnical capacity of the anchor. Large slabs of concrete and rock can also be readily drilled. These anchors work well as both tension and compression tiebacks and can be installed horizontally to meet any tieback or anchoring design criteria.

The application for self drilling anchor soil nailing include the stabilization of enbankments, dams, cuts, unstable slopes and tunnel entrances and the refurbishment of retaining walls.
