[0002] Large-section pipe jacking is increasingly used in urban construction, such as in subway station entrances and exits, and underpasses of existing roads. Urban tunnels have higher requirements for decoration than highway tunnels. Urban tunnels typically use cement fiberboard, steel-calcium veneer, enamel steel plates, and ceramic tiles for decoration. Expansion bolts are then used to fix the keel to the tunnel sidewalls, completing the installation of the cladding. Considering factors such as backfill, soil pressure, buoyancy, structural self-waterproofing, and structural stress, the tunnel sidewalls are usually designed as curved surfaces.

[0003] Because the curvature of the sidewalls of different tunnels varies, the keel needs to be customized according to the actual curvature of the tunnel sidewall to ensure that the finish is vertical and flat after installation. The keel cannot adaptively adjust its installation angle according to the curvature of the tunnel sidewall; the keel can only be installed on tunnel sidewalls with a specific curvature, resulting in poor compatibility.
