Technical Field

The invention relates to the technical field of constructional engineering, in particular to a moisture-proof lightning protection process for a broadcast television tower.

Background

Television towers are buildings for broadcast television transmission and dissemination. In order to make the broadcasting range large, the television transmitting antenna is high, so that the television tower is built higher and becomes the highest building in modern times. To transmit television to each household, the position of the television tower is generally arranged in the urban area, the television tower often becomes the highest building in the city and also the highest point in the city, and the appearance of the television tower is in various postures, so that the television tower becomes a scenic spot in the city. The existing television towers can not only play television, but also can go to tourism, and some television towers are provided with rotary restaurants, which are combined with the tourism industry to form a multipurpose tower. Television towers are typically used as landmark buildings in cities.

As the television tower is built higher and higher, lightning protection becomes an important problem to be faced, the lightning protection scheme of the current television tower generally adopts a large lightning rod arranged on the television tower, occupies large space and is not beneficial to the multi-functionalization of the television tower; meanwhile, most of the current television towers adopt steel pipes as main structures to facilitate circuit wiring, and the moisture-proof problem becomes a significant factor limiting the service life of the steel pipes.
