After the tunnel lining in tunnel construction is finished, waterproof treatment is required, and the waterproof treatment mainly comprises the laying of waterproof boards. Although the initial tunnel support is sprayed, the surface of the initial tunnel support after spraying is still uneven. In order to prevent the waterproof board from being laid on the uneven surface, therefore, geotextile is required to be arranged between the waterproof board and the spray coating layer to form a cushion layer. For a high-speed railway tunnel, the tunnel section is large due to the fact that the running speed of a vehicle is high. Therefore, large-sized geotextile and waterproof sheet are necessarily required, and the conventional method of manually laying geotextile and waterproof sheet cannot be adapted to new requirements.
