[VI-1037] Steel sheet pile driving case to medium hard rock by rock piling method
Keywords:GANPILE Method, Steel sheet pile, hard rock , pile
In the case of steel sheet pile placement on hard ground such as bedrock or ground having ground obstacles, if it is difficult by vibration method or press-in method using water jet together, auxiliary method such as preliminary drilling by other drilling machine It takes a lot of construction period and cost. On the other hand, in the gunpile method, steel piles can be directly driven on hard ground or obstacles without using auxiliary methods. In this paper, the outline of the gun pile method and the steel sheet pile driving example to medium hardness rock whose uniaxial compressive strength qu by this method exceeds 70 MN / m2 are introduced.
