Comprehensive Construction Guidelines for Geomembrane Applications in Tailings Management: Anti-Seepage Implementation and Quality Assurance

Key Sections Highlighted:

1. Pre-Construction Protocols

• Subgrade preparation & material QC testing (ASTM D6392/D6747 standards referenced)

2. Precision Laying Techniques

• Directional deployment strategies for hydraulic optimization

• Dual welding methods (hot wedge/extrusion) with 100mm overlap compliance

3. Anchoring Systems Engineering

• Slope stabilization: 0.5m×0.3m trench anchoring at 5-10m intervals

• Base securing: Ballast placement protocols

4. Protective Layer Specifications

• Gradation-controlled soil/sand layers (min. 0.5m/0.3m thickness)

• Geotextile interlayer requirements (≥200g/m²)

5. QA/QC Framework

• Destructive/non-destructive seam testing (peel/shear, spark testing)

• Final acceptance via hydrostatic testing & seepage monitoring

Technical Value Proposition:
This procedural guide synthesizes geosynthetic engineering best practices with tailings-specific compliance requirements, addressing critical failure points in containment systems through:

• Particle size control for puncture prevention

• Slope-stress-adapted installation geometries

• Multi-layer defense against mechanical/UV degradation

(Note: Title and structure optimized for geotechnical engineers and EPC contractors in mining/environmental sectors. Includes measurable benchmarks for regulatory compliance.)
