The invention discloses a shield tunneling machine hoisting construction method under a 220kV high-voltage line, and relates to the technical field of shield tunneling machine hoisting construction. The method comprises the steps of establishing high-voltage line protection measures of physical protection, technical protection and operator protection; arranging a lightning arrester to track and monitor static electricity of a tower crane; installing a crane limiter; testing the bearing capacity of a foundation; erecting a steel support; hardening a site; and arranging a shield tunneling machine hoisting and dismantling construction site, wherein it is guaranteed that hoisting points of all components of a crawler crane hoisting and dismantling shield tunneling main machine are controlled to be within 10 meters, and the parking position of a flat car is also controlled to be within 10 meters. The problem that a shield tunneling machine is lifted out under the 220kV high-voltage line is solved, construction can be conducted without the shield tunneling machine moving transversely for station platform plate construction, and great social and economic benefits are obtained. According to the shield tunneling machine hoisting construction method under the 220kV high-voltage line, the influence of the high-voltage line on the hoisting of the shield tunneling machine is greatly reduced, and the safety of the high-voltage line, the shield tunneling machine and field operators is ensured.
