Pavement blasting machine is through the mechanical method of the pill material at a high speed and certain Angle shot to work on the surface, shot blasting machine in the beijing-shanghai high iron use let pill material impact of road surface, and make the road surface roughness and the effect of removing residues, and at the same time precipitator creates negative pressure will pill materials and cleaning of the impurity and dust recovery after airflow cleaning, sound pill material will automatically cycle use, and impurity and dust will also fall into dust in the box. This huasheng tai road blasting function a enough will concrete surface laitance and impurity cleaning clear, and can be on concrete surface make wool processing, make its surface even rough, greatly improving the waterproof layer and concrete base adhesive strength, so that the waterproof layer and the combination of deck better, and at the same time can also will concrete crack fully exposed, plays the role of the nip in the bud.
