Description

Technical Field

[0001] The utility model relates to the technical field of angle steel towers for power transmission lines, in particular to a reinforced tower leg structure of an angle steel tower for power transmission lines. Background Art

[0002] The tower leg of the angle steel tower is located at the bottom of the tower. The upper end of the tower leg is connected to the tower body, and the lower part is connected to the foundation. In the tower structure, the tower leg is subject to the greatest force. Therefore, in terms of meeting the strength, stability and deformation requirements, reinforcing the tower leg is a crucial link in improving the overall performance of the tower. The current reinforcement measures mainly include bolting angle steel, but using this method, it is more difficult to machine the openings for the curved parts.

[0003] A Chinese patent discloses a reinforcement device for the bending of the main material of the tower leg of a power transmission angle steel tower (authorization announcement number CN208858233U). This patented technology does not require the replacement of the entire tower. It reinforces and protects the bent part without damaging the main material of the power transmission tower, thereby solving the risk of opening holes in the main material of the power transmission tower. The entire reinforcement device and process are simple and rapid, saving a lot of costs and ensuring the firmness and safety of the power transmission tower.

[0004] However, it has certain disadvantages: it only reinforces the main material of the transmission tower, and the tower leg base plate at the lower end of the main material of the transmission tower is directly installed on the surface of the angle steel tower foundation. The contact area between the tower leg base plate and the angle steel tower foundation is small, which leads to reduced stability of the tower leg and is easily affected by external environmental factors such as wind, earthquake and other factors, thereby increasing the risk of tipping over.
