A pipe boring machine is provided to prevent a pipe from moving by compressing the pipe on a groove, which is formed on a lower block, using an upper block. A pipe boring machine comprises a frame(30) and a pipe fixing part(50). The pipe fixing part includes a drill blade(73), a motor for rotating the drill blade and a cylinder part(99). The cylinder part has a first end fixed to the frame. The pipe fixing part includes a body(53), which has an opening(53a) for the pipe and an opening(53b) for the drill part, an upper block(57) and a lower block(59) spaced apart from the upper block. The upper block is disposed on an upper side of the body and has a groove(57a) mating with an outer upper circumference of the pipe. The lower block is fixed to a lower inner side of the body and has a groove(59a) mating with an outer lower circumference of the pipe. The upper block compresses the pipe mounted on the groove by a cylinder part(55) installed on an upper part of the body. |
