The Subgrade Design about Water Disaster Emergency Rescue on Taiyuan—Jiaozuo Railway |
| |
| Abstract: | The characteristics and difficulties of the emergency rescue engineering is analyzed, that is the engineering with the severely damaged and collapsed subgrade, lending to the partial track suspension and transportation interruption due to extreme rainstorm at the Dongpo Station of Taiyuan—Jiaozuo Railway. The rescue design concept of river channel diversion first, riverbed back pressure and foot reinforcement, ensuring the stable traffic of subgrade first, and then paving revetment at the foot of slope is carried out. Through the rapid restoration of slope by grouting rubble and measures such as paving and reinforcement of pebble riverbed, underwater anti scouring straight skirt wall, template of rebar frame cement composite carpet, they are greatly shorten the construction period. |
