The invention belongs to the technical field of PCCP hoisting construction, and discloses a PCCP hoisting protection system and method close to a high-voltage line. The hoisting protection system comprises an electrified overhead working truck and a tank bottom gantry crane; the electrified overhead working truck is used for sleeving an insulating protective sleeve on the high-voltage line by a person specially assigned to the electrified overhead working truck; the groove bottom gantry crane is arranged in the groove and comprises a gantry frame, electric walking wheels are arranged at the bottom of the gantry frame, and the electric walking wheels are provided with rails and drive the gantry frame to move front and back along the rails. A group of chain blocks are symmetrically hung on the left side and the right side, located on the hoisting pipeline, of the gantry frame, the two opposite chain blocks on the left side and the right side are connected with hanging belts, and the hanging belts are arranged at the bottom of the PCCP in a penetrating mode and used for completing the lifting action of the PCCP through the chain blocks. The construction safety and the normal operation of the high-voltage line can be ensured when the PCCP is hoisted, the hoisting cost is reduced, and the construction operation is safe and reliable.
