The invention relates to the technical field of scaffolds, in particular to a double-layer scaffold for tunnel construction, which comprises a supporting frame, four stand columns, guide sleeve blocks, limiting assemblies, a supporting platform, connecting rods and adjusting blocks, the supporting frame forms a rectangular area in a surrounding manner, and the four stand columns are respectively arranged at four corners of the supporting frame. The device has a fast adjusting mode and a slow adjusting mode, the fast adjusting mode is suitable for the situation that no load exists on the supporting platform, at the moment, the center column and the clamping wheel are kept in a concentric state, the clamping wheel can roll upwards along the stand column, and at the moment, the rolling distance of the clamping wheel is long, so that the moving distance of the supporting platform is long, and efficiency can be improved; the low-speed adjusting mode is suitable for the condition that a load exists on the supportin
