| 摘 要： | 长春市地铁1、2号线联络线下穿建设年代久远的长春市游泳池及附属建筑物。由于受游泳池和地下管线的影响,导致周边降水井难以施做,无法保证联络线暗挖施工无水作业。针对如何确保隧道下穿游泳池施工安全进行了分析研究,最终确定采用了全断面注浆+双排超前小导管注浆的处理方案,并在实际施工中取得了良好的效果。

| Abstract: | The link line of Changchun metro Line 1 and Line 2 is built under an old swimming pool and its ancillary buildings in Changchun City.Influenced by the swimming pool and underground pipelines,the construction of precipitation wells is very difficult,and the excavation of anhydrous operation could not be guaranteed.Through an analysis of the safety in tunnel construction when passing under the swimming pool,a full cross-section grouting + double-line advanced small catheter grouting technology is adopted,which has achieved good resuits in the construction. |
