Construction method of subway shield tunnel laterally-penetrating high-voltage electric tower

The invention relates to a construction method of a subway shield tunnel laterally-penetrating high-voltage electric tower. The construction method comprises the steps that S1, high-voltage electric tower foundations are connected and reinforced; S2, the shield tunnel laterally-penetrating high-voltage electric tower is constructed; and S3, high-voltage electric tower foundation grouting reinforcement is carried out. The construction method of the subway shield tunnel laterally-penetrating high-voltage electric tower has the beneficial effects that two connecting beams are adopted to connect and reinforce the high-voltage electric tower foundations, the high-voltage electric tower foundations are connected into a double-soil-shaped structure, an upper-layer and lower-layer similar frame structure is formed, differential settlement between the high-voltage electric tower foundations can be effectively avoided, the high-voltage electric tower is prevented from inclining, and the safety of the high-voltage elect
