At this time, the first flattening squeezing roller 28 and the second flattening squeezing roller 31 extending forward can push the EVA waterproof sheet 2 located in the limited laying groove 20 out to contact the tunnel wall. The reciprocating movement of the first flattening squeezing roller 28 and the swinging of the second flattening squeezing roller 31 make the EVA waterproof sheet 2 contact the colloid sprayed on the tunnel wall and be quickly and neatly laid on the inner wall of the tunnel. The first laying part 16 and the second laying part 17 as well as the second pressing part 19 and the first pressing part 18 can complete the neat laying of the EVA waterproof sheet 2 on the inner wall of the tunnel at one time.
