Tunnel face reinforcing device for shield tunneling machine construction

The utility model relates to the technical field of shield tunneling machines, in particular to a tunnel face reinforcing device for shield tunneling machine construction, which comprises a tunnel face body and a reinforcing disc. Second soil crushing wheels are arranged at the positions, close to the top, the bottom, the left side and the right side of the first soil crushing wheel, of the tunnel face body, and a reinforcing disc is fixedly connected to the inner side of the tunnel face body. According to the tunnel face reinforcing device for shield tunneling machine construction, the arranged reinforcing disc is matched with the reinforcing block, so that the supporting force of an inner cavity of the tunnel face body is higher, the supporting capacity of the tunnel face body is effectively improved, and meanwhile the arranged supporting fixing disc is matched with the supporting insertion rod, the supporting sleeve and the spring; the supporting force of the tunnel face body is further enhanced, meanwhile
