The common structural form of the high-voltage iron tower foundation comprises an independent foundation, an enlarged foundation and a pile foundation, and the structural form of the high-voltage iron tower mainly adopts a steel structure.
Some overhead high-voltage lines cross the orchard and need to be built in the orchard for supporting. The high-voltage iron tower is arranged in an orchard, the base of the high-voltage iron tower is covered by fruit trees, and as the fruit trees often repel insects and pesticide, chemical residues and cloud mist water in the long term fall on the base of the high-voltage iron tower and the stainless steel rod piece, the rod piece and the cement surface are wet for a long time and corroded by chemicals, so that the stainless steel rod piece at the base of the high-voltage iron tower is corroded seriously and even is broken locally. The stainless steel rod piece at the base part of the high-voltage iron tower is corroded and broken, so that the high-voltage iron tower has the risk of tilting and even collapsing, and great potential safety hazards are caused to nearby things; and the high-voltage iron tower topples or collapses and also causes the high-voltage line to open circuit, causes the outage in large-area areas, and causes great loss. Therefore, when it is found that the pole member of the base portion of the pylon is corroded and broken, it is a very slow matter to repair or replace the pylon. Due to the importance and specificity of the high-voltage iron tower, the whole high-voltage iron tower cannot be replaced, only the rod piece at the base part of the high-voltage iron tower can be repaired or replaced, and the repair or replacement must be carried out on site, so that the stability of the high-voltage iron tower in the process needs to be ensured. Therefore, a practical method for replacing the rod members of the pylon is needed.
