[0002] Shield tunneling, a type of cut-and-cover tunnel construction technology, is widely used in various underground engineering projects such as urban subways, river-crossing tunnels, and mountain-crossing tunnels. Operating in complex underground geological conditions, shield tunneling machines require continuous, efficient, and stable advancement to ensure the quality and progress of tunnel construction. During shield tunneling, the tunnel segments, as key components of the tunnel lining structure, play a vital role in supporting the surrounding soil, resisting groundwater pressure, and protecting the internal facilities of the tunnel. The clamping device is one of the important components for connecting and fixing the tunnel segments, and is crucial for ensuring the connection strength and integrity between the segments.
