Special geological environments such as deserts, Gobi, wastelands, high-altitude permafrost, high temperatures, and saline-alkali wetlands pose challenges to power tower construction, requiring corresponding technological solutions. For example, in "sand-gobi wasteland" areas, the project adopted a "greening and protection" plan, using straw checkerboard barriers and vegetation restoration to reduce the risk of wind and sandstorms. The design must incorporate geological and meteorological analysis to ensure structural stability.
In high-altitude and rugged areas, power tower construction faces challenges in material transportation and tower assembly. Material transportation can utilize mules, helicopters, or high-altitude cableways. Tower assembly techniques include "high-low leg" tower designs to adapt to the terrain and manual excavation of foundation pits. The Tibet-Central China power grid interconnection project is a typical example of this type of construction.
New mechanized and intelligent construction equipment, such as tracked tower assembly devices, has been applied to power tower construction. This device was first used in the Guangxi 500 kV Lijiang substation project, featuring power sharing, mobility, flexibility, and high efficiency, effectively solving the problems of temporary land occupation and guy wire installation.
Power tower safety auxiliary facilities, such as aviation obstruction lights, are used for navigation safety. For example, installing aviation obstruction lights on power transmission towers for Ezhou Huahu Airport is in accordance with civil aviation regulations. The installation process requires working at high altitudes with live electricity, and workers must wear protective suits and maintain a safe distance, making the process complex and time-consuming.
