| Abstract: | In this paper, construction of subway station through the existing ring road is designed. Based on the engineering case, grouting reinforcement the layer of the earth, using the pipe ramming method for reinforcement of the stratum, and designing the ramming parameter, using the steel grille ＋ connecting reinforcing steel bar ＋ insufflate concrete with steel net to support the plug wall, the soil be- tween the existing interval and station vault using horizontal track grouting technology. And reinforcing the existing lines during the construction. |
