Soil Nailing Procedure 1. Site Preparation Survey and Design: Conduct a site survey to analyze the slope or wall and develop a design that specifies the length, diameter, spacing, and inclination of the soil nails based on soil conditions. Excavation: Excavate the area in stages to the required depth. Each excavation is typically around 1 to 2 meters at a time to maintain stability. 2. Drilling Holes for Soil Nails Drill Holes: Bore horizontal or slightly inclined holes (typically 10 to 20 degrees from horizontal) into the soil or rock mass. The diameter of these holes depends on the design but is usually between 75 mm and 150 mm. Hole Length: The length of the hole corresponds to the design requirements for the depth of the nails, typically 3 to 10 meters, depending on site conditions and design. 3. Inserting the Nails Steel Nails: Insert steel bars (commonly 25 to 40 mm in diameter) into the pre-drilled holes. The bars may be ribbed or deformed to enhance bonding with grout. Corrosion Protection: If needed, provide corrosion protection for the nails, either by galvanizing the steel or applying epoxy coatings. Double corrosion protection is typically recommended in aggressive environments. 4. Grouting the Nails Grout Injection: Inject grout (usually a cement-based mix) into the hole around the soil nail to bond the steel to the surrounding soil or rock. The grout is pumped under pressure to ensure full encapsulation and strength. Grouting Techniques: There are two main grouting techniques: Gravity Grouting: Gravity-based injection of grout, typically used for stable soils. Pressure Grouting: Involves pumping grout under pressure for better soil contact and strength. 5. Facing Installation Temporary Facing: Apply a temporary facing, such as shotcrete, wire mesh, or steel plates, to maintain stability during construction. Shotcrete is typically sprayed onto the excavated surface and nails to provide immediate support. Permanent Facing: Once all nails are installed and stabilized, apply a permanent facing (shotcrete, cast-in-place concrete, or precast panels) to protect the surface and ensure long-term stability. 6. Drainage Installation Drainage Provisions: Install drainage systems (such as weep holes or drainage mats) behind the facing to manage water buildup, which can cause pressure behind the soil nails and reduce effectiveness. 7. Monitoring and Testing Pullout Tests: Perform pullout tests on some of the nails to ensure that they meet design strength requirements. Monitoring: Continuously monitor the wall or slope for movement and stress on the nails during and after construction. 8. Final Finishing Finishing: Once the nails and facing are in place and the structure is stabilized, apply finishing treatments, such as paint, protective coatings, or landscaping to improve aesthetics and further protect the system. ??
