Document Type and Number:
Japanese Patent JP2020002682
Kind Code:
A
Abstract:
To provide a pile-shaped ground reinforcement body for a rotary press-in construction method capable of obtaining desired bearing power at low construction cost which can fully utilize a peripheral surface friction force of a reinforcement main body and which enables arrival at a hard ground at a deep position, too.SOLUTION: An acute tip member 3 for penetration is fixed by welding at a tip of a shaft portion 2 comprising a steel pipe, and a blade member 4 for propulsion is fixed by welding at an upper position separated from the tip of the shaft portion, to make a pile-shaped ground reinforcement body 1 for a rotary press-in construction method.SELECTED DRAWING: Figure 1
