IMPLANT TYPE COMPLEX PILE AND CONSTRUCTION METHOD THEREOF

The present invention comprises: a column member which is constructed underground to reinforce the ground; an implant member which is constructed in a smaller diameter than that of the column member, and is installed at the lower end of the column member to be inserted into the lower end of a perforating hole unit constructed underground; and a connecting unit which connects the implant member to the lower end of the column member to fixate the same. Here, the connecting unit is characterized by comprising: a bolt member protruding from the implant member; a screw thread which is formed at a coupling hole unit of the column member to be coupled to the bolt member; and a washer member through which the bolt member penetrates, and which is interposed between the implant member and the column member. Therefore, the number of components required for the construction of an implant type complex pile can be reduced. 본 발명은, 지반을 보강하도록 지중에 시공되는 기둥부재; 상기 기둥부재와 비교하여 작은 지름으로 이루어지고, 상기 기둥부재의 하단에 설치되며, 지중에 시공되는 천공홀부 하단에 삽입되는 임플란트부재; 및 상기 임플란트부재를 상기 기둥부재 하단에 연결하여 고정시키는 연결부를 포함하고, 상기 연결부는, 상기 임플란트부재로부터 돌출되는 볼트부재; 상기 볼트부재와 결합되도록 상기 기둥부재의 결합홀부에 형성되는 나사산; 및 상기 볼트부재가 관통되고, 상기 임플란트부재와 상기 기둥부재 사이에 개재되는 와셔부재를 포함하는 것을 특징으로 한다.
