中深孔注浆技术在饱和富水砂层浅埋暗挖地道中的应用
Application of the Medium-Depth Bore Grouting Technology in Subsurface-Excavation Shallow Tunneling in Water-Rich Saturate Sand Stratum
【摘要】 深圳市深南路—上步路人行地道工程暗挖施工中,采用中深孔注浆技术成功穿过饱和富水砂层,有效地加固了地层,减小了横跨隧道的煤气管、自来水管、污水管等管线的沉降量,确保周边建筑物的安全。
【Abstract】 In subsurface-excavation of Shennan-to-Shangbu road underpass, we successfully penetrate the water-rich saturate sand stratum with medium-depth bore grouting technology, effectively reinforce the stratum guaranteeing the settlement of gas pipe, water supply pipe, sewage pipe that cross the tunnel and ensure the safety for surrounding building
