Geocell Slope Reinforcement Construction: Technical Specifications and Quality Control Protocol

(Subtitle: Standardized Installation Procedures for Geocell Retaining Systems in Slope Stabilization Projects)

Key Construction Stages:

1. Pre-Construction Preparation

• Material verification (ASTM D7864 compliance)

• Subgrade preparation (95% compaction)

• Survey marking (±5mm tolerance)

2. Geocell Deployment

• Anchor trench configuration (300×500mm)

• Node fixation (U-pins at 1m intervals)

• Seam connection (thermal fusion welding)

3. Infill Placement

• Graded aggregate (≤2/3 cell height)

• Layered compaction (150-300mm lifts)

• 90% relative density requirement

4. Surface Protection

• Geotextile overlay (200g/m² minimum)

• Hydroseeding application

• Bioengineering integration

5. Drainage System

• Interceptor ditch (Q=5yr storm)

• Weep holes (Φ50mm@2m grid)

• Toe drain (1:100 gradient)

Quality Assurance Measures:

• In-situ CBR testing (≥15%)

• Pullout resistance test (≥1.2kN)

• Slope stability analysis (FoS≥1.5)

Engineering Benefits:

• 40% increase in shear strength

• 60% reduction in erosion potential

• 25-year design service life

(Note: Complies with ISO 10318 and FHWA-NHI-00-043 standards for slope reinforcement applications.)

Would you like to emphasize specific slope angles (e.g., 45° vs. 70°) or seismic considerations? I can refine the technical focus accordingly.
