With the rapid development of tunnel construction technology, various construction methods have been widely applied in tunnels, especially in railway and highway tunnels. Wet spraying, without a doubt, is a product of tunnel development. However, small wet spraying machines have gradually shown their shortcomings in tunnel projects, mainly manifested in low operational efficiency, high component failure rates, and large manpower and equipment inputs. Currently, large-scale engineering projects require the use of large wet shotcrete machines, which are also the future trend in tunnel construction. The efficiency of these machines is equivalent to that of a dozen small wet spraying machines. In the process of tunnel construction, wet spraying technology has been vigorously promoted, and large concrete wet shotcrete machines have been widely applied, gradually becoming the mainstream method of tunnel construction.

Compared with dry shotcrete machines and small wet spraying machines, large wet shotcrete machines feature wireless remote control, high mechanization, improved construction safety, better working environment, higher efficiency, reduced rebound, and significant economic and social benefits. Large wet shotcrete machines have strongly promoted the application of mechanized construction in tunnels and hold broad prospects for future use.

What Are the Benefits of Installing an Air Compressor on a Shared Concrete Wet Shotcrete Machine?

Function of an Air Compressor:

An air compressor, often referred to simply as an air compressor, is the main component of the air source system. It is a device that compresses air, converting mechanical energy from the prime mover into the pressure energy of gas. It serves as an air pressure generating device for compressed air and is widely used in various industrial and everyday applications. For instance, air compressors are commonly used in construction, steel, mining, and chemical industries. Specifically, twin-screw air compressors are widely used in industries such as machinery, metallurgy, electronics, power, pharmaceuticals, packaging, chemicals, food, mining, textiles, and transportation. It has become the mainstream product for compressed air applications.

There are various types of air compressors, which can be classified based on their working principle: volumetric compressors, reciprocating compressors, and centrifugal compressors. Commonly used air compressors today include piston-type compressors, screw compressors, centrifugal compressors, vane-type compressors, and scroll compressors. Generally speaking, the most common types seen in the market are piston-type and screw-type air compressors. Piston-type compressors have been in use in China for a long time, but due to their high noise levels and numerous wear-prone components, they have been gradually replaced by screw-type compressors.
