Abstract: Provided is a structure for circular connecting parts of press-in square pipe structures using angle reinforcement, which uses a method for pressing closed cross-section square pipes among a non-excavation method. The structure for circular connecting parts of press-in square pipe structures using angle reinforcement allows steel plates in a shape of ㄷ to be connected to each other to form closed cross-sections so that the closed cross-section square pipes are formed, angle-reinforces the closed cross-section square pipes, and connects the press-in square pipe structures through female and male joints, thereby smoothly pressing the press-in square pipe structures, increasing stiffness of corners of the press-in square pipe structures by female and male coupling of the female and male joints, and injecting grout through a grout inlet formed on the female joint to solidly couple the female and male joints.
