Analysis on Key Construction Technology for Curve Pipe Roofing Project of Gongei Tunnel |
| |
| Abstract: | Curve Pipe Roofing Project of Gongbei Tunnel is the control project. The geological condition of pipe roofing is complicated and the surrounding environment is sensitive. The pipe roofing is composed of transition curve and circular curve, which requires accurate roofing to form pipe roofing with great construction difficulties. Through analysis, key technologies like mud-water balance pipe-jacking, pipe-jacking trajectory control and deviation rectification, etc. are adopted for the pipe-roofing construction of curve pipe-roofing project of Gongbei Tunnel, which obtains good effect. |
