The present invention relates to a structure of a power transmission underground pipe fixing apparatus. According to the structure of the power line transmission underground pipe fixing apparatus of the present invention, a power transmission underground pipe is solidly fixed underground because the power transmission underground pipe is buried underground and also is fixed by an underground burial block comprising a flow prevention piece, a bottom supporting part combined to the underground burial block by a protruded steel bar and a connection steel bar, and a top supporting part combined to the bottom supporting part and the underground burial block by an anchor bolt and an anchor nut. The structure also can protect the power transmission underground pipe and an underground power transmission line more safely because the flow prevention piece is protruded at a bottom plane and at both side walls of the underground burial block and thus position change of the underground burial bock due to vibration or impact occurred underground does not occur. And the prevent invention facilitates to perform maintenance and repair of the underground power transmission line efficiently by surveying the position of the underground power transmission line and the power transmission underground pipe by a trenchless method using a survey system comprising an RFID sensor after construction, by forming an RFID casing comprising a casing part and a cover plate on an upper part of the top supporting part, and inserting an RFID tag into the casing part. |
