Novel water stopping structure for tunneling seam in permafrost region

A novel water stopping structure for a tunneling seam in a permafrost region is characterized in that the water stopping structure in the circumferential direction is arranged in an engineering seam of a secondary tunnel lining and annularly laid in secondary lining die construction concrete; the novel water stopping structure is an inflatable water stropping strap and provided with a water flowing groove structure, and the water flowing groove faces towards an inner side cold-proof heat-preserving layer; the inflatable water stopping strap is made of soft materials; the water stopping strap is inflated till the outer wall of the water stopping strap is totally attached to the inner wall of a secondary lining concrete groove; the lower end of the inflatable water stopping strap is connected with a gutter of a skewback of a tunnel. In the tunnel construction and operation period, when the temperature of surrounding rock rises and frozen soil thaws, underground water will naturally flow down along the water stopping strap, enter the gutter of the tunnel and be drained out of the tunnel, and therefore it is avoided that the underground water seeps into the tunnel along the secondary lining engineering seam, and cold damage caused by freeze of the underground water is avoided.
