Automatic metal net roll flattening machine for cast asphalt pavement of road surface
An automatic metal net roll flattening machine for cast asphalt pavement of a road surface comprises an unwinding mechanism, a flattening mechanism and a laying mechanism, which are arranged on a frame, wherein the laying mechanism comprises a pressing-down device; the pressing-down device comprises a pressing-down roller; and the pressing-down roller is arranged above a metal net touchdown position. The automatic metal net roll flattening machine for the cast asphalt pavement of the road surface, provided by the invention, is advantaged in that unwinding, flattening and laying are integrated; as a metal net can sink into asphalt of the road through the adoption of the pressing-down mechanism, problems in the prior art that transverse cracks are prone to form at connections of the metal net and the metal nets are prone to lose balance when secondary road laying equipment moves on the metal nets are solved; and as the density of a hot-mix asphalt mixture in the upper layer is high, rusting, necking and fracture phenomena of the metal nets caused by the invasion of water are avoided; the construction quality is effectively improved; and the working efficiency is effectively increased.
