FIELD: road construction.
SUBSTANCE: principle applies to a field of construction, in particular to installation facility and regulation of beacon level. The technical solution involves ensuring convenience, reliability and utility accuracy and regulation of a level beacon. The installation utility and regulation of a level beacon consists of threaded rod connected to a pivotal element, in the form of an anchor with an external threading. The rod consists of upper and lower parts, made with a possibility of screw driving its ends on into the other. On the other end of the upper part, the interaction with the beacon, is done by means of preventing its rotation during screwing the parts one into the other. On the other end of the lower part, which is connected to the anchor, there is an external thread that correspond to the internal anchor thread. The external thread has a direction, opposite to the direction of the threads on the ends of the upper and lower part of the rod.
EFFECT: ensuring convenience, reliability and utility accuracy and regulation of a level beacon.
