摘　　要：随着公共交通的普及发展,地上交通逐渐达到饱和状态。地下建筑具有良好的防护性能,较好的稳定性和密闭性,以及综合的经济、社会和环境效益,地下建筑与地下交通越来越受到追捧。随着地下建筑的兴起发展,地下建筑的深度越来越深,施工难度越来越大,目前中国超深竖井施工技术仍较为欠缺。红土地站为重庆轨道交通十号线一期工程的第2座车站,车站整体位于重庆轨道交通6号线下,与6号线垂直交叉,为中国最深地铁站。3号风井位于红土地站小里程端,其截面尺寸为6.7*18.3m,高度91m,为中国最深竖井。3号风井墙面存在异型,安装工程量大,施工现场安装工程难度大。项目部通过组织课题攻关,优化施工方案,并且聘请专家论证施工方案,加强过程控制,研发了一套91m超深竖井管道及设备安装施工技术,保证了施工安全与质量,确保了施工工期。With the popularization of public transportation,ground transportation has gradually reached saturation.Underground buildings have good protection performance,better stability and tightness,and comprehensive economic,social and environmental benefits.Underground buildings and underground transportation are increasingly sought after.With the rise and development of underground buildings,the depth of underground buildings is getting deeper and deeper,and the difficulty of construction is getting larger.At present,China’s ultra-deep shaft construction technology is still relatively lacking.Hongtudi station is the second station of Chongqing Rail Transit Line 10 phase I project.The station is located under Chongqing Rail Transit Line 6 and crosses with line 6 vertically.It is the deepest subway station in China.No.3 air shaft is located at the small mileage end of laterite station,with a section size of 6.7*18.3m and a height of 91m.It is the deepest shaft in China.The wall surface of No.3 air shaft is irregular,the installation work is large,and the installation work on the construction site is difficult.The project department has developed a set of 91m ultra deep shaft pipeline and equipment installation and construction technology by organizing the research and optimization of the construction scheme,employing experts to demonstrate the construction scheme,strengthening the process control,ensuring the construction safety,quality and the construction period.
