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.

    本发明属于PCCP管道吊装施工技术领域,公开了一种临近高压线PCCP管道吊装防护系统及方法。吊装防护系统包括带电高空作业车和槽底龙门吊;带电高空作业车用于由带电高空作业车专人给高压线套上绝缘保护套;槽底龙门吊设置在沟槽中,包括龙门框架,龙门框架底部设有电动行走轮,电动行走轮配设有轨道,电动行走轮驱动龙门框架沿轨道前后移动;龙门框架位于吊装管道的左右两侧对称挂设有一组手拉葫芦,左右两侧相对的两个手拉葫芦连接有吊带,吊带穿设于PCCP管道底部,用于通过手拉葫芦完成PCCP管道的升降动作。本发明能在PCCP管道吊装时确保施工安全以及高压线正常运行,降低吊装成本,施工操作安全可靠。
