What precautions are required when building a power tower?

1. Safety Regulations

- Workers working at heights must be certified and wear a safety harness (impact force ≤ 6kN) and a safety net (mesh density ≥ 2000 mesh/100cm²).

- Construction is prohibited during winds of force 6 or above or during thunderstorms.

2. Materials and Corrosion Protection

- Tower materials are primarily Q345B low-alloy steel, with a galvanized layer thickness ≥ 86μm (GB/T 13912-2020).

- Regularly inspect for rust. If the rust area exceeds 3%, partial replacement is required.

3. Environmental Protection and Acceptance

- Construction waste (such as waste galvanizing solution) must be handled professionally to avoid soil contamination.

- A load test must be conducted after completion (e.g., no deformation after applying 1.2 times the design load for one hour).

Additional Notes:

- Special terrains (such as permafrost areas) require deep pile foundations, with a depth of 4 meters or more.

- New prefabricated towers can shorten construction time by 30%, but increase costs by 15%-20%.
