HELICAL ANCHOR PILE
The present invention relates to a helical anchor pile. The present invention is capable of firmly joining connection heads to the anchor piles by screw-coupling a helical anchor pile body, a first connection head joined to the same, a first shaft pile anchor, second connection head joined to the same, a second shaft anchor pile, a third connection head joined to the same using a male and a female screw unit and welding the first connection head to the helical anchor pile body, the second connection head to the first shaft anchor pile, and the third connection head to the second shaft anchor pile respectively; thereby smoothly constructing the helical anchor pile by preventing a separation of the connection heads from the anchor piles even when a storing torque is applied. The present invention is capable of minimizing a resistance of a cut ground by interpenetrating the helical anchor pile after forming cut portions on an outer circumference of helixes equipped in the helical anchor pile; improving the ground cutting performance by including a cutting blade on the cut portions; effectively excavating and cutting by excavating the ground with an excavation crown before cutting the ground with the helixes by joining the excavation crown made of a material with excellent cutting force and including a cutting tip on the outer circumference of the lower part of the helical anchor pile and a cutting tip on the lower end of the helical anchor pile. Accordingly, the present invention is capable of constructing the helical anchor pile even the helical anchor pile can be constructed through a bedrock, rapidly constructing the helical anchor pile by reducing a burden to the helixes for cutting, and economically constructing the helical anchor pile by constructing the helical anchor pile even with a small hydraulic rotary device.
