Concrete shotcrete machine is a kind of shotcrete support equipment widely used in underground engineering, geotechnical engineering, municipal engineering and other fields. Concrete shotcrete machine is generally divided into two categories: concrete dry shotcrete machine (also known as dry shotcrete machine) and concrete wet shotcrete machine (also known as wet shotcrete machine). The concrete dry spraying machine is a method of mixing cement, sand and stones evenly in a dry state. Restricted in use. When the concrete dry spraying machine works, the dust concentration near the machine is large, the rebound rate is high, and the working environment quality is poor, which seriously endangers the health of workers.
Concrete wet spraying machine solves many problems of concrete dry spraying machine to a great extent. The wet spraying process has the advantages of small shotcrete rebound, high utilization rate of concrete raw materials, and high engineering quality standards, which improves the construction of shotcrete. quality. At the same time, the concrete wet spraying machine has the advantages of fast construction progress, good adhesion of shotcrete, and high compactness. It also effectively reduces the dust pollution of shotcrete and improves the construction work environment.
With the continuous development of construction technology, the requirements of engineering quality, operation safety, occupational health and other aspects have been continuously improved. Concrete wet shotcrete machines are widely used in more and more shotcrete support projects. Concrete wet shotcrete machines are widely used in railways, highway tunnels, slopes, water conservancy, hydropower tunnels and culverts, subways and various construction projects and other wet shotcrete operations.
