Method for reducing foundation grounding resistance of power transmission tower
The invention relates to a method for reducing the ground resistance of a transmission tower foundation, which is characterized in that an original foundation base arranged below the soil surface and an original foundation main column arranged on the original foundation base are included, an original foundation reinforcement cage is arranged on the original foundation main column, the periphery of the original foundation main column is provided with a reamed hole from the soil surface to the original foundation base, and the reamed hole is communicated with the original foundation base. The expanded hole forms an annular cavity, a post-added longitudinal bar and a post-added stirrup hooped on the post-added longitudinal bar are arranged in the annular cavity, and conductive concrete is cast in the annular cavity; the method is suitable for power transmission or distribution line foundation grounding transformation in regions with frequent thunderstorm or regions with large geological soil resistivity; the method is simple and convenient, the foundation grounding resistance of the power transmission line can be effectively reduced, and the bearing capacity of the grounding foundation is enhanced.
本发明涉及一种降低输电杆塔基础接地电阻的方法，其特征在于：包括设在土面以下的原基础底座和设在原基础底座上的原基础主柱，所述原基础主柱上设有原基础钢筋笼，所述原基础主柱的外周设有自土面至原基础底座之间的扩孔，该扩孔形成环形腔，所述环形腔内设有后加纵筋和箍设在后加纵筋上的后加箍筋，所述环形腔内浇铸有导电混凝土；本发明适用于雷雨频繁地区或地质土壤电阻率较大地区的输电或配电线路基础接地改造；本发明的方法简便，能有效降低输电线路基础接地电阻，增强接地基础的承载能力。
