[0041] In this embodiment, a slope drainage channel 1 is constructed outside the tower base engineering area, and a water storage pit 3 and a water diversion channel 4 are constructed in the tower base area. Water is introduced into the water diversion channel 4 and enters the water storage pit 3. When the water is full, the water flows out of the tower base. In the process of constructing the water diversion channel 4, the height of the water outlet is ensured to be lower than the water inlet, so that the water flows through but does not gather under the tower base. Six planting hole soil columns 6 are evenly arranged on both sides of the tower base area, so that the water diversion channel 4 passes through the water storage pit 3 and penetrates it. When the water storage pit 3 is filled with water, the soil of each planting hole soil column 6 can store water, providing the necessary moisture conditions for plant growth;

[0042] Thereby, water is introduced into the tower base through the water diversion channel 4. When the water flows through each planting hole soil column 6, the moisture is stored in the soil of the planting hole soil column 6, increasing the moisture reserve in the tower base area, thereby improving the soil moisture conditions within the disturbance range of the tower base construction and realizing the vegetation restoration of the transmission and transformation tower base area with a high gravel content.
