[0002] High-voltage towers play a supporting role for transmission lines, and their stable structure is of great significance for the normal operation of transmission lines. However, due to the continuous upgrading of the construction of transmission lines, as well as the frequent disasters such as earthquakes and floods, the load-bearing capacity and stability of the foundation of high-voltage towers are a great test. When the high-voltage tower is impacted, it is easy for the high-voltage cable supported at the top to break, thereby affecting the power transmission and seriously affecting people's production and life. Therefore, the foundation of the high-voltage tower must be improved to ensure the normal supply of electricity. Most of the current high-voltage tower bases are cast by cement, such as a basic structure that can reduce the lateral displacement of the high-voltage tower disclosed in CN218713236U, and the bottom is reinforced with anchor bolts to ensure that it is fixed to the ground, but its foundation is easy to cause the head of the high-voltage tower to shake violently when it is impacted by earthquakes and floods, thereby causing the cable at the head to break.

There are eight grouting support pipes 4 in total; the eight grouting support pipes 4 work together with the longitudinal base column 2 to prevent the integral concrete pouring structure formed by the shock-absorbing foundation 1 and the square frame structure from overturning when it is hit by disasters such as earthquakes or floods, and at the same time prevent it from tilting in a certain direction, causing the high-voltage line above the high-voltage tower to be broken under stress.
[0029] A grouting hole is provided at the center of the longitudinal foundation column 2, into which concrete is poured after being placed into the soil layer to improve the overall strength of the longitudinal foundation column 2.
[0030] A hydraulic shock-absorbing structure is arranged at the center of the shock-absorbing foundation 1, which is used for shock absorption and vibration reduction of high-voltage towers; the hydraulic shock-absorbing structure includes damping fluid 6, a shock-absorbing chamber 7 and a movable groove 8; a weight block 9 is fixedly connected to the lower end of the support leg 5, and the weight block 9 is arranged in the shock-absorbing chamber 7; the weight block 9 is provided with small through holes 10 for the flow of the damping fluid 6; the interior of the shock-absorbing chamber 7 is filled with the damping fluid 6; the movable groove 8 runs through the shock-absorbing foundation 1, and is used to set the support leg 5, and a sealing member 11 is arranged between the movable groove 8 and the support leg 5, which is used to seal and prevent leakage of the damping fluid 6.
