| titleOfInvention | Construction method of small-radius curve segment of shield tunnel |
| abstract | The invention discloses a construction method of a small-radius curve section of a shield tunnel, which is characterized in that in the construction process of the shield tunnel, when a shield machine advances for a certain distance, an automatic measurement system of the shield machine is checked by adopting a small-radius measurement and check method, the deviation between the shield posture of the shield machine and the design central line of the tunnel is controlled, and the shield posture of the shield machine tends to the design central line of the shield tunnel by shield deviation correction. The invention ensures that the deviation accords with the national acceptance standard by controlling the deviation between the shield posture of the shield machine and the design central line of the tunnel, ensures the shield clearance by reducing the deviation between the shield posture and the design central line of the tunnel, and solves the quality problems of segment fragmentation and water leakage by arranging the water stop according to the curve wedge amount of the tunnel. |
