In particular, the present invention relates to a flipping track capable of guiding and flipping shield segments, reducing the difficulty of flipping operation of shield segments, and simultaneously being capable of flipping and transporting multiple groups of shield segments in the track, without requiring additional kinetic energy to provide flipping force, and having low power consumption. Background Art

[0002] The shield segment is the main assembly component of shield construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. Usually, the manufactured shield segments need to be flipped 90 degrees for stacking. Generally, the direction is flipped and adjusted manually by a suction cup hanger. The flipping of the segments is cumbersome. In the prior art, the segments are flipped by a flippable suction cup hanger. However, this flipping method causes the flipping shaft of the hanger to be subjected to a large load and is easily damaged. In addition, the power consumption required for flipping is large. At the same time, only one segment can be flipped and stacked at a time, which is inefficient.
