Detail
The present invention is a method for improving soft ground on land by forming a compaction pile in soft ground using a ball-type casing pipe.
To this end, it is composed of a penetration process for lowering a ball-type casing pipe to a support layer, an injection process for injecting a grain-adjusting aggregate into the pipe, a drawing process for discharging the grain-adjusting aggregate, a re-penetration process for expanding the grain-adjusting aggregate, and a repeating process for forming a grain-adjusting aggregate compaction pile by repeating these processes.
At this time, at least one or more of crushed stone, gravel, concrete crushed stone, stone powder, sand, and blast furnace slag can be used as the grain-adjusting aggregate.
