The present invention relates to an insulating buried screw installed in a structure around rails in order to fix a frame supporting a trolley wire which is installed on the rails in a tunnel or an underground chamber, and a method of installing the frame of the trolley wire using the same. More specifically, the insulating buried screw comprises: an insulating member which has a supporting recess having female threads formed on the inside surface thereof by one end which is opened, male threads on the outer surface thereof, and a coupling recess formed at the one end which is opened, to insert the frame; and a fixing member engaged with the supporting recess and provided with the male threads corresponding to the female threads on the outer surface thereof; a supporting member which is fixedly combined with the fixing member and is fixed by the fixing member to prevent the frame mounted on the fixing member from being separated or removed. The insulating buried screw prevents the frame from being in direct contact with water, thus preventing the frame from being corroded. In addition, by adopting an anchoring installation method, the present invention facilitates installation and maintenance of a buried screw. |
