Introduction to Road Type Shot Blasting Machine

The road surface type shot blasting machine mainly solves the defects in the treatment of concrete surface layer. It can clean and remove the laitance and impurities on the concrete surface in one go, and can roughen the surface of the concrete to make it uniform and rough, greatly improving the adhesion strength of the waterproof layer and the concrete base layer, so as to better combine the waterproof layer and the bridge deck, and also fully display the cracks in the concrete, Play a preventive role. The centrifugal shot blasting machine is a clean and dust-free method for treating bridge decks with impurities on hard surfaces. This method uses a high-speed rotating impeller inside the shot blasting equipment, where abrasives, dust, and impurities are cleaned to the debris recycling machine. The cleaned steel balls can be recycled. The concrete surface after shot blasting treatment is clean and hard, with relatively uniform textures. On an unobstructed horizontal surface, This method is particularly applicable.

The purpose of the shot blasting machine

1. Used to improve the roughness and friction coefficient of asphalt pavement and enhance its adhesion. At the same time, the attachments of asphalt pavement (such as fuel, engine oil, etc.) are also nowhere to escape, thus improving the skid resistance of the road surface;

2. Steel bridge deck anti-corrosion coating

In China, the application of shot blasting technology in anti-corrosion coating of steel bridge beams cannot be denied. Most bridges under construction and already built choose to use shot blasting technology for surface cleaning and roughness treatment before undergoing anti-corrosion primer or other spraying. The shot blasting machine used for Qingdao Cross Bay Bridge can meet the steel plate cleanliness requirements of SA2.5/SA3 and control the roughness to meet the user's coating requirements. The entire process is dust-free and easy to move, It is both environmentally friendly and convenient.

3. Maintenance of tunnels

In China, due to considerations such as waterproofing, fire and oil resistance of materials, cement concrete is generally used for the pavement inside tunnels. But this also puts forward high requirements for the anti slip performance of long tunnel pavement. For the two problems that are still difficult to solve in China, shot blasting technology is a simple construction, small equipment investment, significant effect, and environmentally friendly treatment method.

In the waterproof pavement of concrete bridge decks, shot blasting technology is already a requirement of process specifications in European and American countries, and is gradually being accepted in China. Shot blasting technology is used to maintain concrete pavement.

4. Preventive maintenance of airport runways

The use of road blasting machines makes it easy and simple to remove tire marks and markings on concrete and asphalt runways. Removing tire marks (rubber removal), removing markings, restoring and increasing the surface roughness of airport runways, and improving the friction coefficient of runways are all within the processing range of road surface shot blasting machines. And during the processing, the road surface shot blasting work was carried out in an orderly and effortless manner.

5 Municipal roads and paved surfaces

Various road pavements in cities can be cleaned using shot blasting machines to remove signs and markings on the road surface. For busy intersections, the road surface can be roughened to improve road roughness and friction coefficient. Reduce problems in road construction. Therefore, the auxiliary role of road blasting machines in urban construction is gradually standardizing and facilitating our lives.
