摘要
济南泉域地区水资源丰富、水压大、地层复杂且渗透系统大,常规的端头加固方法难以取得理想的止水效果。某地铁车站施工中对高压旋喷加固法,水平冷冻法和钢套筒法进行对比,首次在泉域地层采用钢套筒+辅助减压井的盾构机接收方法,并取得成功。
Ji’nan spring area has rich water resource,high hydraulic pressure,complex stratum and large water seepage,so ordinary end strengthening method could not realize ideal water-stop effect.High-pressure rotary spraying method,horizontal freezing method and steel sleeve method were compared with each other in a subway station construction.It was the first time to use the shield machine receiving method of steel sleeve plus auxiliary pressure relieving well.It is successful application.
