The present invention relates to a seamless type circularly knitted fabric tube for reinforcing and repairing a trench-less pipe. The circularly knitted fabric tube of the present invention is to optimally reinforce the strength of the tube and adhere to the pipe through strong adhesive strength by being lined on an inner peripheral surface of the pipe to repair the pipe to the same level as a new pipe, forming the seamless circularly knitted fabric tube to have a triply or more structure, and being impregnated with resins having different uses in accordance with the use thereof. The seamless type circularly knitted fabric tube for reinforcing and repairing a trench-less pipe comprises: a coated fabric tube, a mesh fabric tube, and a boundary fabric tube, which are knitted seamlessly and circularly; and first and second thermosetting resins, wherein the mesh fabric tube and the boundary fabric tube are impregnated with the first and second thermosetting resins, respectively. The first thermosetting resin is used to control the thickness of the pipe, and made of a mixture of a liquid resin and a filler. The second thermosetting resin is used to allow the circularly knitted fabric tube to adhere to an internal wall of the pipe, and is made of any one selected from the group consisting of epoxy. The circularly knitted fabric tube of the present invention has a layer structure of the coated fabric layer, the mesh fabric layer impregnated with the first thermosetting resin, and the boundary fabric layer impregnated with the second thermosetting resin from the inside through thermosetting of the first and second thermosetting reins.
