COMPOSITE PILE
The present invention relates to a synthetic pile. When a complex pile, which is fixated by stacking the synthetic pile on a PHC pile, is constructed, if the length of the complex pile is needed to be extended due to sudden change of the depth of a support layer, a steel pipe pile is joined to a connection unit, which is not covered by a steep pipe, and then the steel pipe pile is welded and fixated to the steel pipe of a synthetic unit. In addition, a support reinforcing material is embedded in an inner circumferential side of an upper end portion of the steel pipe to obtain welding thickness between the steel pipe and the steel pipe pile. At the same time, driven energy, applied to the steel pipe pile, and the weight are smoothly transferred to the steel pipe of the synthetic unit and the PHC pile located in the steel pipe. Consequently, while compression strength and bending strength of the synthetic pile are increased, the length of the complex pile can be extended in an easy manner according to the grounds condition.
본 발명은, PHC 말뚝에 합성말뚝을 적층하여 고정하는 복합말뚝을 시공함에 있어 지지층의 깊이가 급변해서 복합말뚝의 길이를 연장해야 할 경우, 강관이 덮혀있지 않은 연결부에 강관파일을 결합한 후, 강관파일을 합성부의 강관에 용접하여 고정함은 물론 강관의 상단부 내주면에 지지보강재를 내장하여 강관과 강관파일 간의 용접두께를 확보함과 동시에 강관파일에 가해지는 항타에너지 및 하중이 합성부의 강관 및 강관 내부에 위치하는 PHC 말뚝에도 원활하게 전달되도록 함으로써, 복합말뚝의 압축강도 및 휨강도를 증대시키면서 지반 조건에 따라 복합말뚝의 길이를 손쉽게 연장할 수 있는 합성말뚝에 관한 것이다.
