In recent years, with the development of mobile communications, the scale of wireless networks of major operators has become larger and larger, and the demand for building signal towers on the ground has become more and more extensive. The single-tube tower is widely used because of its simple structure, convenient installation and small footprint. Because of this, the safety of the single-tube tower is very important. At present, the connection structure of the tower body of the single-pipe tower mainly adopts two structures of flange connection or plug-in connection.

However, the bolts in the flange connection are subjected to high stress. After long-term work, the material of the bolts is prone to yield and creep, which reduces the degree of tightening and damages the tightness of the connection. At this time, the tower body has a certain inclination. At this time, the flange connection works in a bent state, which may easily lead to cracks in the flange connection, and the construction and installation of the flange connection is difficult and slow; the plug connection has a great impact on the processing technology. The requirements are high, and it is difficult to completely match the ends of the upper and lower tower sections at the plug-in point, and gaps are easy to form, resulting in damage to the tightness of the connection. The plug-in nodes under the action of wind load are also prone to tearing and damage, resulting in structural destroy.
