Background At present, in order to stably fix outdoor facilities (road railings, road sound insulation sheds, street lamps, billboards and other outdoor facilities) on a base, a plurality of thread strips are embedded on the base to form a member for locking the outdoor facilities, and the method is specifically realized by embedding one end of each thread strip in the base and exposing the other end of each thread strip outside the base; the support legs of the outdoor facility are sleeved on the other ends of the thread strips, nuts are screwed on the other ends of the thread strips, and the support legs are clamped and positioned through the nuts and the base, so that the outdoor facility can be positioned. Among them, in order to provide a reliable positioning strength for the thread bars, a large length is often used for the thread bars, and a large portion of the thread bars is buried in the base.
