うように曲線施工ができないという欠点があった。Conventionally, in the tunnel construction method using a shield excavator, in order to easily perform curved construction, the main body of the shield excavator is divided into multiple pieces. There are some that have more braking control. However, a plurality of these hydraulic cylinders were provided on the left and right sides of the main body, and were operated independently of each other. Therefore, according to this method, when changing the traveling direction of the shield excavator, it is difficult to push and pull the left and right hydraulic cylinders at the same time, and there is a drawback that curve construction cannot be performed as desired.
