TIP STRENGTHENING APPARATUS FOR PHC(PRETENSIONED SPUN HIGH STRENGTH CONCRETE) PILE
The present invention relates to a tip strengthening apparatus for a pretensioned spun high-strength concrete (PHC) pile, wherein the tip strengthening apparatus is mounted on the tip of a PHC pile to enhance a frictional force by being inserted while scraping an inner circumference surface of a hole to smooth the inner circumference surface when the PHC pile is inserted into the hole punched in the ground; and enhances a bearing capacity of the tip by introducing slime, water, cement, etc. below the hole into the PHC pile. According to the present invention, the tip strengthening apparatus for a PHC pile comprises: a fixed part fixated to a lower end part of the PHC pile having one or more inflow holes which intercommunicates with the hollow part of the PHC pile formed to penetrate; and an inclined part formed on the fixed part to protrude while being inclined downwards outside an outer circumference surface of the PHC pile, having a ring shape capable of being in contact with the inner circumference surface of the hole when the PHC pile is inserted into the hole punched in the ground.
