Problems solved by technology

Incomplete design drawings, scattered data, and lack of sufficient understanding of the importance of TV tower construction by the builder resulted in poor production and installation quality of the tower, and eventually collapsed and damaged under the design wind pressure far below the specification requirements
In addition, the design service life of the earlier transmission towers in my country is 25 to 30 years, and a large number of steel towers have been in service close to or even exceeding the design service life at that time, and the safety and reliability of the structure have been greatly reduced.

Embodiment approach

[0016] refer to figure 1 , taking the 103.2-meter radio and television tower in a certain place as an example, the specific ideas and implementation methods of the steel structure radio and television transmitting tower structural safety monitoring technology in this embodiment are as follows:

[0017] The total height of the tower is 103.2 meters, of which there is a microwave antenna 1 at an elevation of 27 meters, and multiple FM antenna sections and decimeter wave antenna sections are installed above 32 meters, such as figure 1 shown. Firstly, through finite element analysis, understand the structural characteristics (including parameters such as mode shape) and grasp the overall information of the structure. Since the microwave antenna has requirements for the structural rotation angle, a two-way orthogonal inclination sensor A2 can be installed on the tower column at an elevation of 29 meters, and a two-way orthogonal inclination sensor B3 and anemometer 4 can be instal...

Abstract

Disclosed in the invention is a structure safety monitoring technology for a steel-structure radio and television transmitting tower. With the existing steel-structure radio and television transmitting tower as a carrier, a tilt angle sensor and a wind-velocity indicator are used for monitoring the deformation and wind speed of the steel tower for long time and a relationship between the wind speed and the structural inclination angle is established; and the information is compared with a numerical value simulation result, thereby evaluating the structure safety. The operation is simple; the data are accurate; and the cost is low. A collapse accident can be prevented timely and unnecessary casualties and economic losses can be avoided.

Description

technical field [0001] The invention belongs to the field of steel structure safety monitoring, and in particular relates to a structure safety monitoring technology of a steel structure radio and television transmitting tower. Background technique [0002] As an important high-rise structure, the steel structure radio and television transmission tower has the characteristics of high and soft, and the internal force and deformation under the wind load are relatively large. If there are deficiencies in the design or construction, it may lead to collapse accidents under the wind load casualties and economic losses. In our country, between June and July 1990, there were six consecutive collapse accidents of TV towers and communication towers in Cangzhou and Hengshui areas of Hebei Province, three of which were products of the same company. The six self-supporting steel towers are 83 meters high and 50 meters low. The tower types are triangular steel pipe towers and quadrilat...
