Abstract: With the continuous development of the 10 kV distribution network in rural areas, the upgrading and renovation of rural distribution networks have also ushered in higher reliability and safety. This article takes the 10 kV tower line renovation project of the 110 kV Dongping Station in Sihui, Zhaoqing as an example, focusing on the construction of the 10 kV distribution network tower foundation. When encountering complex sandy geology and unable to change the tower position, the construction technology optimization and improvement are carried out.
