Abstract
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.
Description
Technical field
The present invention relates to a kind of automatic flattening machine of metal net volume, more particularly to a kind of mat formation for road surface cast asphalt
The automatic flattening machine of metal net volume.
Background technology
With the further investigation to the technology such as asphalt characteristic and Anti-reflective Crack of Overlaying, relative settlement, cast asphalt
Compound bilayer paves and metal mesh reinforced technology has become the hot spot technology of road surface and bridge floor Asphalt mixture pavement.In basic unit
Lay metal mesh reinforced energy between surface layer to provide enough resistance to tensions to prevent reflection crack, road surface layering and relative settlement
Appearance.At present in cast asphalt paving work progress, metal net volume is generally using strange land flattening, Manual
Mode.This strange land flattening, the mode of Manual can not realize continuous construction, inefficiency, and easily cause constructor
Member is injured;In addition, easily in junction generation transverse crack between wire netting, the secondary roadway paving apparatus in road surface are in metal online mobile
When easily cause the unstability of wire netting, cause the hot-mix asphalt mixture density on upper strata relatively low, cause the intrusion of water so that gold
Category net corrosion, constriction and fracture.Application No. 201310634032.2, publication No. is 103590304, and date of publication is 2014 2
The Chinese patent on the moon 19 discloses the automatic flattening machine of steel wire net volume that a kind of road surface cast asphalt is mated formation, including vehicle frame, car
There are steel wire unreeling structure, steel wire flattening mechanism and steel wire to mat formation mechanism on frame, the steel wire flattening mechanism includes driving
Dynamic device, drive roll, the upper hold-down roller arranged close to drive roll top and the lower hold-down roller arranged close to drive roll bottom, actively
