Practice of freeze and sand prevention technologies in wind power project construction
风电工程施工防冻防沙技术实践

摘要

我国风电产业在我国北方有广泛分布，风电工程建设面临冻害以及风沙问题的严峻考验，在非高寒区域以及沙化土地条件中，风电项目施工过程中会涉及多项关键技术。风机基础工程以及设备吊装需要处理冻土难题，同时完成低温条件下的混凝土作业，设备运行维护工作会面临挑战，风沙侵蚀的防护工作以及沙害治理成为关键。开展冻土作用下的桩基稳定工作，低温会对混凝土性能造成损害，风沙会磨损电气设备且掩埋塔筒基础，因此，提出了控温措施包括材料改性、结构优化以及生态固沙方面的综合技术方案。

Abstract

China’s wind power industry is widely distributed in the northern regions of the country, where wind power project construction faces severe challenges from frost damage and wind-blown sand. In non-permafrost areas and under sandy land conditions, the construction of wind power projects involves multiple key technologies. The foundation engineering for wind turbines and equipment installation require addressing permafrost challenges, along with completing concrete work under low-temperature conditions, while equipment operation and maintenance face difficulties. Protection against wind-sand erosion and sand hazard control become critical. Research is conducted on pile foundation stability under frozen soil conditions, as low temperatures can impair concrete performance, and wind-blown sand can wear down electrical equipment and bury tower foundations. Consequently, comprehensive technical solutions are proposed, including temperature control measures, material modification, structural optimization, and ecological sand fixation.
