SOIL REINFORCING DEVICE AND METHOD

摘要

A soil reinforcing device comprises an elongate, substantially rigid, soil reinforcing element (23), and a drive tube (27) surrounding the reinforcing element (23) and adapted to move into soil with the reinforcing element. Subsequently the drive tube (27) is withdrawn from the soil while leaving the reinforcing element (23) in the hole (30) left after withdrawal of the drive tube (27). A helix (24) is secured to the end of the reinforcing element (23) and is adapted to move into the soil with the reinforcing element (23) when the helix is rotated. The drive tube (27) is removably secured to the helix (24) at the distal end of the drive tube (27) and is arranged to drive the helix (24) into the soil when the drive tube (27) is rotated. The helix (24) has dimensions and configuration such as to draw the reinforcing element (23) into the soil by screwing into the soil without auguring soil out of the hole (30) in the soil.
