Detail
This is about a high-pressure injection device that combines a hammer and a rod, and a soft ground improvement method using it.
This method can perform both the excavation work and the injection of the injection material into the soft ground with just one rod insertion and extraction operation without replacing the rod or removing the air hammer, and it has the effect of drastically reducing the construction time for soft ground improvement and allowing soft ground improvement work to be performed without construction errors even in the sea where rolling phenomena such as barges occur.
