Abstract
The invention discloses a bottom jacking type lifting steel structure radar tower which comprises a tower body, a standard section supporting device and a jacking device. The tower body is formed by connecting tower body standard sections. Connecting pieces are arranged at the two ends of each tower body standard section and used for butt joint of adjacent tower body standard sections. Jacking supporting points are arranged on the tower body standard sections. The standard joint supporting device is arranged on the inner side of the tower body and used for supporting the tower body in the tower body jacking process. The length of the standard section supporting device is larger than that of the tower body standard sections. The jacking device is used for moving the tower body from a first height position to a second height position, and the difference value of the first height position and the second height position is larger than or equal to the height of one tower body standard section. The bottom of the radar tower can be heightened, top radar equipment and the like do not need to be demounted, normal operation of the radar equipment is achieved, and the problem that the height of the radar tower needs to be increased later due to the fact that the planned height is insufficient is effectively avoided.
