The average diameter of a sand drain typically varies from 25 to 40 cm.
Understanding Sand Drains
Sand drains are a type of prefabricated vertical drain (PVD) or wick drain used in geotechnical engineering, particularly for improving soft, compressible soils. They are installed to accelerate the consolidation process by providing pathways for pore water to escape from the soil under surcharge loading.
According to the provided information:
- These are prefabricated drains placed in the soil using specialized equipment.
- Average sand drain diameters range from 25 to 40 cm.
- Depths of 40 to 45 meters can be reached during installation.
- Average installation production rates range from 70 to 100 linear meters per hour, influenced by soil characteristics.
Key Specifications
Here's a summary of typical sand drain characteristics based on the reference:
- Diameter: 25 to 40 cm (average range)
- Maximum Depth: Up to 40 - 45 meters
- Installation Rate: 70 - 100 linear meters per hour (average production)
These drains play a crucial role in large infrastructure projects built on challenging soil conditions, allowing for faster settlement and increased soil strength over time.
