Aught-Set performs a range of ground services including surveys, soft ground improvement and reinforcement. They also manufacture and sell solidification materials for use in ground improvement. Their environmentally friendly solidification materials are sparking interest as the focus on the health of the earth grows.

Expansion Piles for Soft Ground

When constructing a civil engineering project or other structure, foundation piles must generally be driven into the ground to reinforce the earth.

However, conventional pile driving causes vibrations and noise pollution, and a more recent solution of an auger drilling holes in advance and then burying the support piles has the environmental problem of leaving a great deal of earth during excavation.

Aught-Set has solved these problems with an expansion pile technique, wherein a spiral blade and an excavation blade are attached to the end of a pile, and the pile is inserted into the support ground while rotating.

One special feature of this technique is that the spiral blade is welded to the end of the pile to increase the support capacity of the end. Because there is a limit to the surface area that can be ensured, the excavation tip part is used as a bowl-shaped expansion pile to increase the pressure receiving surface area, and then a large-diameter blade is mounted on the excavation tip part, enabling a greater support force. This enhances the economy and reliability of Aught-Set’s unique technique.
