Geocell Reinforced Retaining Wall Construction: Technical Specifications and Quality Control Protocol

Key Technical Components:

1. Pre-Construction Engineering Controls

• Subgrade preparation to ≤5mm/m² tolerance

• Material QC per ASTM D7864 standards (tensile strength ≥25kN/m)

2. Structural Assembly Framework

• Modular geocell deployment with interlocking connectors

• Anchoring system: 0.5-1.0m vertical spacing of soil nails (ϕ16mm, L=3m)

3. Mechanized Backfilling Protocol

• Gradation-controlled fill (GW-GM soils) in 300mm lifts

• 95% Proctor density achieved via vibratory compaction

4. Hydraulic Management Systems

• Composite drainage: 300mm granular filter + geotextile-wrapped weep pipes

• 2% cross-slope drainage at coping level

5. Performance Validation

• Laser scanning for ≤1:200 vertical alignment tolerance

• Load testing to 1.5x design bearing capacity

Engineering Value Proposition:
This specification establishes optimized construction practices for geocell walls through:

• Seismic performance enhancement (PGA 0.3g compliance)

• 40% reduction vs. conventional MSE walls

• 50-year service life assurance
