RD pile wall is a retaining wall made of tubular steel piles. Installation of RD pile walls is done by drilling which makes them suitable for very difficult ground conditions. Drilling enables penetration through hard soil layers, stones and embedding the piles into the bedrock. But besides that, it enables also penetration through soft soil layers like clay and silt which makes installation possible to variating and layered grounds.
In this webinar we will present the features of RD pile walls, such as
- The basic components of RD pile walls; pile sizes, connectors and drill bits
- Percussive drilling with DTH hammer as installation method
- Installation equipment; piling rig sizes, DTH hammer sizes and required air compressors
- Comparison to sheet pile walls and combined pile walls
- Available manuals and designer tools
- Case examples
