As core infrastructure for communication networks, communication lattice angle‑steel towers operate in open‑air environments. Subject to wind loads, salt‑fog corrosion and external impact, they are prone to component rusting, member deformation and loose bolts. Timely and standardized repair is critical to network stability and tower structural safety.
Repair starts with on‑site survey and assessment. Technical teams deploy drone aerial surveys and non‑destructive testing equipment to identify hazards including tower corrosion, bent members, joint conditions and foundation performance. Internal steel defects invisible to naked eyes are examined to classify damage severity and generate inspection reports, which serve as the foundation for formulating repair solutions.
Tailored solutions are developed according to damage levels. Minor corrosion is addressed via rust removal and anti‑corrosion treatment. For structural damage such as deformed or fractured main members, corresponding angle‑steel components shall be replaced. The plan also takes weather conditions and material lead‑time into account. Construction is preferably arranged during off‑peak communication hours to minimize signal service disruption. During material procurement, replacement components must comply with original design specifications to guarantee material and dimensional compatibility with the existing tower structure.
Safety is prioritized for high‑altitude operations. Warning zones are set up on‑site. Workers are fully equipped with fall‑protection PPE. Pre‑work safety briefings and emergency response plans for unexpected incidents are mandatory. During construction, corroded sections go through complete anti‑corrosion procedures including rust removal, priming and top‑coating. Damaged members are installed and removed with hoisting equipment. Precise component alignment and bolt tightening torque are strictly controlled, with quality spot‑checks conducted throughout construction.
Upon completion of field work, structural load verification and commissioning tests for communication equipment are performed. The tower can resume service only after all indicators meet requirements. Repair completion is not the end of work. Regular inspection regimes shall be implemented to monitor anti‑corrosion coatings and bolt tightness, mitigate potential risks in advance and extend the overall service life of the tower.
