Isolation device for road corner points in municipal road construction

The utility model relates to a road construction isolation technology, in particular to an isolation device for a municipal road construction road corner point, and aims to solve the problem that an isolation mode of enlarging the occupied area is difficult to use in a smaller construction area of a mountain road. According to the technical scheme, the top of a through groove is connected with a rotating rod capable of rotating to adjust the angle through a rotating assembly, the lower end of the rotating rod is connected with a threaded rod capable of adjusting the extending length, a nut is fixed to the lower end of the threaded rod, a drill bit inserted into the ground is arranged at the lower end of the nut, and a rubber sleeve used for containing the drill bit is arranged at the bottom of the through groove; the isolation assembly has the beneficial effects that the base and the chain are combined with the improved isolation supporting rod, the chain can change the bending degree, so that the bending deg
