Embodiment 1
[0040] Implementation Example 1: Reference Figure 1 to Figure 5 , a reinforcement method for adding anchor bolts to the foot plate of an old line iron tower, the method includes: first calculating the foundation force of the iron tower, and judging whether the bearing capacity of the foot plate of the tower meets the actual use requirements; The foot plate of the tower is carried out including the outer edge of the bottom plate 5 connecting the outer bottom plate 9, the outer anchor bolt 8 lofting and the reinforcement of the connection stiffener 10; by increasing the force transmission area between the foot plate and the foundation 7, the strength of the foot plate position is improved. Carrying capacity.
[0041] Preferably, the calculation method of the force of the iron tower foundation 8 includes: first calculating the electrical load effect of the iron tower under various combinations of working conditions, and then calculating the action of the iron tower foundation un...

The invention discloses a method for reinforcing tower foot plates of an old line iron tower by newly adding foundation bolts. The method comprises the steps that firstly, the acting force of an iron tower foundation is calculated, whether the bearing capacity of the tower foot plates meets the actual use requirement or not is judged, and then the tower foot plates which do not meet the actual use requirement are subjected to reinforcing transformation including connection of outer spliced bottom plates on the outer edges of the bottom plates, lofting of the outer foundation bolts and connection of stiffening plates. According to the method, the force transmission area between the tower foot plates and the foundation is increased, so that the bearing capacity of the tower foot plates of the iron tower is improved; and the implementation method is simple and easy to operate, the economic benefits are good, and the application range is wide.
Description
technical field [0001] This patent relates to a reinforcement method for adding foundation bolts to the foot plate of an old line iron tower, which belongs to the field of overhead transmission line engineering. Background technique [0002] The transmission line tower is used as the supporting point of the overhead transmission line, the wire and the ground wire are connected to the transmission tower, the load is transmitted to the foundation through the tower, the tower foot plate and the foundation bolts are used as the connection between the tower and the foundation, and the pouring of the foundation is completed Afterwards, its bearing capacity has been determined and there is no possibility of replacement. However, with the improvement of design standards and changes in use requirements, especially in winter, the icing phenomenon is serious, and the force transmitted to the foundation through the iron tower has increased. The phenomenon of insufficient bearing capacit...
