With the continuous development of tunnel construction technology, the requirements of tunnel engineering quality, operation safety, occupational health and other aspects have been continuously improved. In each process of tunnel construction, mechanized equipment has gradually been used instead of manual labor. Tunnel concrete wet spraying machine has become the mainstream of shotcrete operation. equipment.
The tunnel concrete wet spraying machine adopts wet spraying operation, the concrete spraying is uniform, the quality is stable, the strength is high, the adhesion is good, the compactness is high, the rebound amount is small, the dust concentration beside the machine and outside the nozzle is reduced, and the health of the workers is eliminated. It can improve the construction work environment and reduce the construction cost.
The tunnel concrete wet spraying machine has the advantages of high construction efficiency, stable construction quality, strong construction safety, and good construction environment, which can better meet the increasingly high construction quality and construction period requirements in the domestic construction field.
The “One Belt, One Road” strategy will drive my country’s large-scale construction units to participate in infrastructure investment and project construction in countries along the route, which will inevitably involve a large number of tunnels and underground projects, such as urban subways, highway tunnels, railway tunnels, high-speed rail tunnels, water Down tunnels, municipal pipelines, etc., the application of tunnel concrete wet spraying machines will also become more and more extensive.
