Protection measures for high-voltage lines of tower cranes?

The crane arm of Building A 1# of this project does not meet the safe distance from the high-voltage line. According to the requirements of electric power bureau, necessary protective facilities must be set up to ensure safe construction.

According to the requirements of the Electric Power Bureau, the installation scheme of protective facilities is as follows:

1, the protective frame is not less than 4m away from the high-voltage line, steel pipe double-row scaffolding is used below the high-voltage line, and bamboo and wood are used above the high-voltage line. The height exceeds the upper high-voltage line by not less than 4m. Protective frame should be firm and stable, with wind resistance.

2. The scaffold step is 1.8m, the vertical distance is 1.8m, and the cross bar step is1.8m. The top of the steel pipe scaffold shall not exceed the minimum high-voltage line. Scaffolding should be set with scissors and transverse braces. And set up 2-3 landing throws in the south. The throwing bracket must be firmly connected with the ground.

3, steel pipe scaffold erection to the lower part of the high voltage line, the use of bamboo erection. Protective frame erection layout as shown in the figure.
