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.

Application Preventive pile Steel pipe pile
EPS pile Concrete pole foundation and so on
Bedrock excavation work Landslide prevention work
