The invention belongs to the technical field of telegraph poles, and particularly relates to a composite telegraph pole in a coastal beach area. The composite telegraph pole comprises a pole body. Theouter side of the pole body is sleeved with a folding sleeve. The folding sleeve comprises a plurality of annular sharp cylinders which are sequentially connected. An annular impact plate is connected between every two adjacent annular sharp cylinders. A fixing ring is fixedly connected to the top of the folding sleeve. According to the composite telegraph pole in the coastal beach area, throughthe folding sleeve and a lifting plate, after the pole body moves down, the fixing ring can be pushed to move up, after the annular sharp cylinders are mutually extruded, the folding sleeve is integrally contracted, and the annular impact plate between every two adjacent annular sharp cylinders is convex; and when seawater impacts on the pole, the seawater firstly impacts on the convex annular impact plates, the seawater can be blocked at a far position, the situation that the service life of the pole body is shortened due to the corrosion of the pole body can be prevented, meanwhile, when thepole body tilts, a large contact area between the whole and the ground can be guaranteed through the lifting plate, and the inclination probability of the pole body is reduced.
