Abstract

The invention provides a fabricated hollow sandwich steel tube concrete pole which comprises at least two hollow sandwich steel tube concrete members. The hollow interlayer steel pipe concrete member comprises an inner layer, an outer layer of a hollow structure and a prefabricated interlayer. The inner layer is arranged in the outer layer in a sleeving manner; the interlayer is arranged between the inner layer and the outer layer; the inner layer and the outer layer are made of the same material; the interlayer is made of different materials from the inner layer and the outer layer; when two adjacent hollow sandwich steel tube concrete members are connected, the inner layers of the two hollow sandwich steel tube concrete members are connected, and the end portions of the outer walls of the outer layers of the two hollow sandwich steel tube concrete members are connected. The hollow sandwich concrete-filled steel tube member provided by the invention is prefabricated and produced, the assembled hollow sandwich concrete-filled steel tube electric pole is formed in an on-site splicing mode, construction and installation are convenient, and time and labor are saved.
