1. Application of road shot blasting machine.
?
1) tunnel maintenance. In China, cement concrete is generally used in tunnel pavement due to the consideration of waterproof, material fire resistance and oil resistance. But at the same time, it also puts forward higher requirements for the skid resistance of long tunnel pavement. In recent years, there are more and more projects using shot blasting technology to treat bridge deck and tunnel under the recommendation of users. In the waterproof pavement of concrete bridge deck, shot blasting technology has been the requirement of European and American countries' process specifications, and is gradually accepted in China. For example, Chongqing Tongyu tunnel, Guiyang yingpanpo tunnel, Kunshi Expressway Qingshuigou tunnel and so on, all adopt shot blasting technology to concrete pavement Maintenance.
?
2) surface treatment of concrete bridge deck. With the increase of traffic volume, the diseases of water-proof layer, surface layer and bridge deck bond strength are insufficient. In China, similar diseases often occur in concrete bridges, as well as concrete loosening, falling off and steel corrosion caused by water seepage. One of the reasons for the above-mentioned diseases is that the treatment of concrete surface layer can not completely remove the residual substances on the surface, and does not retain a certain rough surface to ensure the bonding strength between the waterproof layer and the bottom layer of the bridge deck.

Shot blasting technology can clean up and remove the laitance and impurities on the concrete surface at one time. The most important thing is to roughen the concrete surface at the same time to make the surface even and rough, and greatly improve the bonding strength of waterproof layer and concrete base. And in this process, the shot blasting process can fully expose the concrete cracks and other diseases, so as to take remedial measures in advance.
?
3) municipal road and pavement. All kinds of road pavement in the city can be cleaned by shot blasting machine to remove the signs and markings on the road surface. The road surface can be roughened at busy intersections to improve the roughness and friction coefficient of the road surface.
?
4) preventive maintenance of airport runway. Concrete and asphalt runways can remove tire marks (except rubber), remove markings, restore and increase the surface roughness of airport runway, and improve the friction coefficient of runway.
?
5) maintenance of asphalt pavement. Shot blasting equipment is widely used to improve the roughness and friction coefficient of asphalt pavement, so as to improve the adhesion of pavement and ensure the driving safety. At the same time, it can also remove the attachment of asphalt pavement (such as fuel oil, engine oil, etc.). The asphalt surface treated by shot blasting not only cleans all kinds of surface attachments, but also increases the roughness of asphalt surface and improves the performance of asphalt pavement. Moreover, the equipment construction is simple, convenient and flexible.
?
6) anti corrosion coating of steel bridge surface. The application of shot blasting technology in anti-corrosion coating of steel bridge has been fully affirmed in China. Most of the bridges under construction and already built choose to use shot blasting process for surface cleaning and roughness treatment before anti-corrosion primer or other spraying, such as Tongsan expressway, Qinghuang sea bridge, Qinghuang undersea tunnel, Jiaozhou Bay Bridge, etc. The steel bridge deck treated by shot blasting process can meet the cleanliness requirements of sa2.5/sa3, and the roughness can be controlled to meet the coating requirements. Moreover, the whole process is dust-free and easy to move.
 Road blasting machine 550mm wide

1. Product introduction: the 550mm wide road surface shot blasting machine uses mechanical method to shoot shot materials onto the working surface at a high speed and a certain angle, The shot blasting machine is used in Beijing Shanghai high speed railway to make the surface of the road surface rough and remove the residue. At the same time, the negative pressure generated by the dust collector will recover the shot material and the impurity dust. After air cleaning, the intact shot material will be recycled automatically, and the impurities and dust will also fall into the dust collection box. The pavement shot blasting machine can clean up the floating slurry and impurities on the concrete surface at one time, and roughen the surface of the concrete to make the surface even and rough, greatly improving the adhesion strength of the waterproof layer and the concrete base, so as to better combine the waterproof layer and the bridge deck, and fully expose the cracks of the concrete, so as to play a preventive role

2. Working principle: 550mm wide The road shot blasting machine uses the shot blasting wheel driven by motor to generate centrifugal force and wind force in the process of high-speed rotation. When the projectile with certain particle size flows into the shot feeding pipe (which can control the projectile flow), it will be accelerated and brought into the high-speed rotating shot wheel. Under the action of centrifugal force, the shot is thrown from the window of the dividing wheel into the directional sleeve, and then thrown through the directional sleeve window (controlling the throwing direction of the shot) The projectile is picked up by the high-speed rotating blade and moves continuously along the length direction of the blade until it is thrown out. The ejected projectile forms a certain fan-shaped beam, which impacts the working plane and plays a role in cleaning and strengthening. Then the projectile, dust and impurities together pass through the rebound chamber to the top of the hopper. The high-power dust remover separates the shot material and dust through the separation device above the storage hopper. The shot material enters the storage hopper and continues to be recycled. The dust enters the dust collector through the connecting pipe. When the dust enters the dust collector, it stays on the surface of the ash storage hopper and the filter element through the separation of the filter element. The automatic back blowing dust remover can clean each filter element automatically through the back blowing air provided by the compressor. **After that, through the air flow cleaning of the matching vacuum cleaner, the shot material and the impurities are recovered respectively, and the shot can be reused. The shot blasting machine is equipped with dust remover, which can achieve dust-free and pollution-free construction, which not only improves the efficiency, but also protects the environment.

3. Product application: the effective shot blasting width of 550mm is 550mm, which is especially suitable for large-scale highway bridge waterproof construction, high-speed railway bridge waterproof construction, shot blasting treatment of large workshop floor, waterproof treatment of underground parking lot, etc. The machine also plays an important role in cleaning large steel plates. It has been used in many large national road and bridge construction projects, such as Shanghai Kunming passenger dedicated line, Beijing Shanghai passenger dedicated line and so on.
