Introduction of Construction Methods
Down The Hole Hammer Method
(DH Pile construction)
Using hammer excavation, it is good for heavy-mineral prospecting and bedrock.
It uses a percussion mechanism which rapidly breaks and excavates such heavy-minerals and bedrock.
Debris caused by excavation is discharged by being blown out by compressed air.
Since it does not use slurry, it does not require a mud water plant and uses fewer incidental facilities, resulting in easy carrying in and out.
