Geocell

1. Structural Composition

Geocells consist of high-strength HDPE/PP copolymer strips ultrasonically welded into:

• 3D cellular matrix (typical cell size: 200×200×100mm)

• Modular panels (4×8m standard size) with 600-800kN/m tensile strength

2. Stabilization Mechanisms

2.1 Load Distribution

• Confinement effect: Increases bearing capacity by 300-500%

• Lateral restraint: Reduces aggregate movement by 70%

2.2 Drainage Enhancement

• Permeability: 10⁻³ cm/s (ASTM D4716)

• Pore pressure reduction: 50% faster consolidation

3. Performance Advantages

4. Construction Protocol

4.1 Site Preparation

• Remove vegetation and debris

• Grade to ≤3% cross-slope

• Install edge drains (if water table >500mm)

4.2 Deployment Procedure

1. Panel layout: Align major axis with traffic direction

2. Anchoring:

• Perimeter: 300mm trench backfill

• Intermediate: 1m spike spacing

3. Infilling:

• 20-40mm crushed aggregate

• 150mm lift thickness

• 92% relative compaction

4.3 Quality Control

• Laser-level surface verification (±10mm)

• Plate load testing (EV2 ≥60MPa)

• Infill gradation analysis (per ASTM D6913)

5. Technical Specifications

6. Economic Benefits

• 60% cost reduction vs. traditional gravel beds

• 5:1 load improvement ratio

• 20-year design life in permanent installations
