APPLICATION FIELD

Suitable for concrete buildings such as roads, dock buildings, dams, hydropower stations, tunnels, bridges, etc.

The high-pressure water concrete roughening machine uses a high-pressure pump to pressurize the liquid to a predetermined pressure to quickly roughen the top surface, facade, corners and other parts of the poured concrete. Under the scouring of high-pressure water, the emulsified layer on the concrete surface quickly peels off, and the concrete surface becomes coarse sand, meeting the surface treatment requirements and making the new and old concrete tightly bonded.

In engineering construction, construction joints are formed at the junction of new and old concrete. The quality of roughening at the construction joints will affect the continuity of the concrete structure, which is not conducive to the bending and shear resistance of the concrete. The phenomenon of dislocation when the concrete is bent is extremely unfavorable to the structural force of the concrete. The roughening treatment of concrete construction joints has always been a common construction problem that is difficult to completely solve. Traditional roughening methods include manual roughening, roughening machine roughening, and pneumatic pick roughening. During the roughening process, the labor intensity of the operators is high and the noise is loud, but the effect is minimal. The floating slurry at the construction joints is always not thoroughly treated and cannot achieve the ideal effect.

Ultra-high pressure water roughening machine is a kind of equipment that uses high-pressure water jet technology to treat the surface of concrete. In the construction of buildings, roads, bridges and other fields, it can remove impurities such as slurry and oil stains on the surface of concrete, making its surface rougher and increasing adhesion.

The roughening treatment of the old concrete surface by high-pressure water jets has little disturbance to the surrounding concrete. At the same time, the concrete surface is clean and moist after roughening, which is easy for the new and old concrete to combine better. It uses the principle of liquid supercharging to convert the mechanical energy of the power source into pressure energy through a high-pressure pump. The water with huge pressure energy passes through a small-hole nozzle and then converts the pressure energy into kinetic energy, thus forming a high-speed jet. The huge water jet force removes the cement stone on the interface of the old concrete, exposing the rough aggregate on the surface of the interface, thus forming an uneven bonding interface, improving the bonding strength of the interface between the new and old concrete, with the advantages of simplicity, speed, efficiency, noise reduction, and economy.

High-pressure water roughening machine is suitable for roughening concrete in any situation. There is no vibration, noise and dust during operation. The construction is highly mechanized and fast, with almost no disturbance to the old concrete. The surface roughness is good. As the roughness of the bonding surface increases, the bonding contact area is increased, thereby improving the bonding performance of the new and old concrete. The test results show that the roughness of the bonding surface obtained by different water pressures is also different, so the jet pressure can be adjusted to obtain the desired effect.

It can be seen that the ultra-high pressure water roughening machine is an efficient, environmentally friendly and economical concrete surface treatment equipment, which has a wide range of application prospects in all walks of life. By understanding the equipment selection and parameter setting, operation process and precautions, common problems and solutions, maintenance and service life, etc., we can better use and maintain the equipment and improve the construction effect and safety.
