Green Geocell Slope Protection System: Eco-Engineering Solution for Vegetation Restoration

Technical Features

1. Slope Stabilization

• Increases shear strength by 30-50% through soil confinement

• Reduces surface erosion by ≥80% under 50mm/hr rainfall

2. Vegetation Enhancement

• Root Development:

• Provides 3D growth space (typical cell size 200×200mm)

• Extends root depth 2-3x vs. unreinforced slopes

• Hydrological Benefits:

• Retains 15-25L/m² moisture capacity

3. Construction Efficiency

• Installation Rate: 300-500m²/day with 3-person crew

• Adaptability: Conforms to 1:1 to 1:3 slope gradients

Installation Protocol

1. Site Preparation

• Surface Requirements:

• Remove all debris >50mm

• Achieve ≤30mm/m surface irregularity

2. Geocell Deployment

• Laying Sequence: Base-to-crest with 5% prestress

• Connection Standards:

• Polymer connectors @ 500mm spacing

• Overlap seams ≥100mm

3. Soil Infill

• Growth Medium:

• 60% topsoil + 30% compost + 10% hydrogel

• Placement in 150mm lifts

4. Vegetation Establishment

• Planting Options:

  Method	Density	Coverage Time
  Hydroseeding	80g/m²	60-90 days
  Plug plants	9-16/m²	30-45 days

Performance Data

▸ Slope Stability: FOS improvement from 1.2 to 1.8
