SW Soil Nailing
By inserting them into the ground at close intervals, the resistance and shear strength of the original ground are increased, ensuring the stability of the slope.
Method Overview
- By inserting reinforcement at close intervals into the ground, this method increases the resistance and shear strength of the original ground, ensuring slope stability and suppressing displacement. The SW Soil Nailing method enhances the overall shear strength of the ground by inserting four auxiliary rebars, spaced at regular intervals, into drilled holes. A bearing-type bolt integrated into the head of the rebar is attached to the bearing plate, which is then pressed tightly against the slope surface, minimizing deformation.
Features & Benefits
- Integrated with four auxiliary rebars around the main rebar, it enhances the overall shear strength of the original ground.
- The attachment of a bearing-type head increases pull-out resistance through both frictional and bearing forces, while pressing against the slope surface helps prevent surface failure.

Process
Drilling
Considering the position, drilling diameter, length, and direction according to the design documents,
In ground conditions where the borehole wall cannot stand on its own, drilling is performed while inserting a casing.

Anchor Assembly and Installation
It must be positioned at the center of the hole, and spacers are used to connect the nailing materials.
Care should also be taken to ensure that the surface coating layer is not peeled off.

Grouting
Ordinary Portland cement or high-early-strength cement is generally used, and the grout mixture follows the standard specifications.

Bearing Plate Installation
Tightening is carried out to ensure that the bearing plate (head) is completely and securely in contact with the cut surface.
