In order for the above-mentioned caps to effectively bear the load of the iron tower, the volume of the concrete caps needs to be large enough to make the caps resist various loads of the iron tower, which will lead to a huge amount of concrete, increasing the cost of raw materials and construction costs
[0004] Moreover, when the concrete cap is backfilled with soil to bury the concrete cap after the concrete cap is poured to reinforce the concrete cap, if the backfilled soil is relatively soft, its reinforcement effect on the concrete cap will be weak, which will cause the cap to fail. Effectively resist various loads of the iron tower, prone to the phenomenon of the tower overturning or collapsing

Abstract
The invention discloses a step type anchor rod foundation which comprises a foundation pit, a bearing platform used for bearing downward pressure of an iron tower and a locking part used for bearing upward pulling force of the iron tower; the bearing platform is of a plate-shaped structure horizontally arranged in the foundation pit; and the locking part vertically and downwards penetrates through the foundation pit and is connected with the bottom of the bearing platform. When the step type anchor rod foundation is used, supporting legs of athe iron tower can be installed on the bearing platform, so that the bearing platform can effectively bear downward pressure applied by the iron tower; and due to the fact that the bearing platform is of the plate-shaped structure horizontally arranged in the foundation pit, the contact area of the bearing platform and the supporting legs is effectively increased, so that the phenomenon that the bearing platform is damaged when being squeezed downwards is avoided, and the collapse phenomenon of the iron tower is avoided. Meanwhile, the locking part which penetrates through the foundation pit vertically and downwards and is connected with the bottom of the bearing platform can effectively bear upward pulling force applied by the iron tower, so that the locking part and the bearing platform are prevented from being pulled upwards by the iron tower, and then the phenomenon that the iron tower overturns is avoided.
Description
technical field [0001] The invention relates to the technical field of transmission line iron towers, in particular to a stepped anchor foundation. Background technique [0002] In the prior art, the tower body of the transmission line iron tower is usually installed on the foundation at the bottom, and the foundation includes a cap for supporting the tower body. The iron tower generally has four legs, and each leg is correspondingly installed on the cap. The foundation usually needs to bear the two loads of the uplift force and the downforce of the iron tower. For example, when a strong wind blows the iron tower, it is assumed that the blowing direction of the natural wind is figure 1 The middle arrow indicates the direction, which will make the tower tend to tilt to the left. At this time, the cap on the left side of the tower will bear the downforce exerted by the tower, and the cap on the right side of the tower will bear the uplift force exerted by the tower. [0003] ...
