Building Pressed-in Pipe Pile Walls for Landslide Prevention-PPT Presentation

PPT Presentation

Pdf Summary

The presentation describes the use of pressed-in pipe pile walls for landslide prevention at a railway bridge project in Japan. The approach uses rows of pipe piles installed securely into bedrock to form a robust stabilizing structure in ground that includes cracked mudstone.<br /><br />The press-in method pushes piles into the ground using hydraulic force, without impact or vibration, making it quieter and less disruptive than conventional piling. For hard ground and rock, the Gyropress method rotates pipe piles fitted with cutting shoes while applying press-in force, allowing installation through difficult materials.<br /><br />Construction is supported by the Giken Reaction Base (GRB) system. Its equipment can transport, position, and install piles from the tops of already-installed piles, enabling work on steep slopes with reduced reliance on access from the ground. Skip Lock attachments allow piles to be installed at 2.5 times the pile diameter on center.<br /><br />The presentation concludes that properly installed pipe pile rows can provide effective landslide prevention, while Gyropress enables installation into rock and the GRB system supports safe, economical construction in challenging terrain.
