Tunnel lining technology and device

The invention discloses a tunnel lining technology. The tunnel lining technology is characterized by comprising the steps that a lining reinforcement cage is divided into a plurality of reinforcementsplicing blocks which are machined and formed outside a tunnel and then conveyed into the tunnel; a lining form board is divided into a plurality of form board pipe segments which are machined and formed outside a tunnel and then conveyed into the tunnel; the reinforcement splicing blocks and the form board pipe segments are spliced; a corresponding number of concrete pouring work surfaces of thecorresponding dimensions are arranged according to the working period requirement and the splicing speed of the reinforcement splicing blocks and form board splicing blocks; and the lining form boardpipe segments are disassembled after lining concrete reaches the strength allowing the lining form board to be disassembled, and tunnel lining is completed. The splicing blocks of the lining reinforcement cage and the splicing
