摘要
在海拔超过5000 m的超高海拔冻土区建设光伏电站时,电站易受冻融、缺氧、气候恶劣等不利因素的影响,因此在进行光伏支架微孔灌注桩基础施工时,不能完全照搬低海拔地区的施工方法,而应充分考虑项目所在地的水文地质条件、气候条件、环境因素等的影响。以西藏自治区双湖县的可再生能源局域网光伏电站为例,对超高海拔冻土区光伏支架微孔灌注桩基础的施工工艺和施工方法进行了探究,总结出了一套简便实用的施工方法,以期为同类工程施工提供参考。
Construction method of micro-hole cast-in-place pile foundation used in low altitude area can’t be completely copied in the construction of PV power station in ultra-high altitude(over 5000 meters)frozen soil area due to the influence of adverse factors such as freeze-thaw,anoxia and climate.The engineering hydrogeological conditions,climatic conditions and environmental factors should be fully considered.This paper introduced the construction process of the renewable energy local area network PV power station in Shuanghu County,Tibet Autonomous Region,explored the construction technology and construction method of micro-hole castin-place pile foundation of PV support in ultra-high altitude area,and summarized a set of simple and practical construction method,which supplies reference for the construction of similar projects.
