| Abstract: | Technology of rectangular pipe jacking machine go in and out of tunnel is a key technology in pipe jacking technology. Combined with Xicitang lane underground passage,this paper introduces the existing problems and related construction measures. The supporting form of tunnel entrance ,soil reinforcement of tunnel entrance ,sealing ring installation dewatering well arrangement are also introduced. By using this technology measures,the risk is controlled well. |
