Transmission towers are important power transmission devices and are widely used worldwide. The transmission tower is in service in the field for a long time and bears various strong load actions and severe environmental actions. The coastal areas in the south of China are strong wind areas, and wind-induced collapse accidents of transmission towers are frequently generated throughout the year, so that serious losses and secondary disasters are caused. Therefore, development and application of disaster-resistant reinforcement technology for transmission towers are necessary.
The prior transmission tower adopts angle steel as a main material, and the angle steel is connected through bolts. Aiming at the wind resistance reinforcement problem of the transmission tower, related researches at home and abroad at present propose different types of reinforcement devices which are mainly divided into two main types: drilling reinforcing apparatus and anchor clamps formula reinforcing apparatus. The wind-resistant reinforcement device of the early transmission tower mainly adopts a drilling reinforcement mode, and wind-resistant reinforcement of the structure is realized by drilling holes on the original tower rod pieces and installing reinforcement materials. The reinforcement mode needs a large amount of high-altitude operation, is complex in field operation, and simultaneously holes are drilled on the original rod pieces, so that the original rod pieces are damaged to a certain extent, and the reinforcement mode belongs to a damaging reinforcement method.
In recent years, some clamp-type tower reinforcing devices have been developed, wherein a clamp is arranged on a reinforcing member, the clamp is connected with an original tower member, and the bearing capacity is transferred through the extrusion force and the friction force in the clamp, so that the reinforcing is realized.
