【摘要】 青藏交直流联网工程格尔木接地极极环地处沙漠地带,海拔高、气候条件恶劣,建设环境复杂。在沙漠地带进行极槽开挖极易出现滑坡及坍塌,这是本工程施工安全控制的重点;在气候恶劣条件下,焦炭敷设过程中纯度的保证和馈电钢棒焊接质量的控制,是本工程质量控制的关键点。文章介绍了高海拔沙漠地区接地极极环的施工技术应用,保证了沙漠地区接地极施工过程中的安全和质量,施工后的各项指标满足设计及规范的要求。更多还原

【Abstract】 Golmud grounding electrode polar ring of Qinghai-Tibet AC and DC Interconnection Project is located in the desert,with high altitude,harsh climatic conditions,and complex building environment.It is prone to landslides and collapse with polar trench excavation in the desert,it is the key points of engineering quality control that guaranteed pure coke laying process and the feeding steel bar welding quality control under the climate severe conditions.The paper introduces the construction technology of grounding electrode polar in high-altitude desert regions,to ensure that the safety and quality of grounding electrode construction in the desert regions,the indicators after the construction meet the design and specification requirements.更多还原
