Abstract
Description
Technical Field
[0001] This utility model relates to the field of power grid construction technology, and in particular to an in-situ emergency repair and reinforcement structure for double-layered main material angle steel towers. Background Technology
[0002] Transmission line systems play a crucial role in regional energy distribution strategies, primarily undertaking the important tasks of transmitting and distributing electrical energy. Transmission towers, as the main load-bearing structures within these lines, are typical wind-sensitive structures. Overhead transmission lines are characterized by their wide geographical distribution, diverse environmental routes, and complex corridor environments. Transmission lines and towers are exposed to the natural environment for extended periods, making them susceptible to damage from natural conditions and external forces. The collapse of a transmission tower often leads to line paralysis, causing widespread power outages and potentially triggering cascading effects across various sectors, resulting in significant economic and property losses. For transmission towers with long service lives, due to factors such as weather recurrence intervals and differences in design specifications, the design conditions of these towers may fall below current requirements, resulting in lower reliability. These towers frequently collapse in strong winds. Reinforcing and strengthening these towers can improve their resistance to strong winds and ensure their safe operation. Summary of the Invention
