During the spraying operation, it's important to start the air supply before starting the pump and to stop the pump before turning off the air supply. This is done to prevent cement slurry from entering the air circuit. After spraying the concrete, the air passage should be opened after cleaning, and then the nozzle should be removed.…

The management of equipment is essential for wet spray vehicles and other concrete equipment like mixing pumps and trailer-mounted concrete pumps. The rapid development of society has led to the emergence of various types of concrete equipment companies.…

The tunnel wet shotcrete machine is a widely used construction device both domestically and internationally, known for its excellent performance in dust reduction, rebound minimization, and material saving in anchor bolt spraying and support applications. It uses compressed air or other power sources to mix materials in a specific ratio and then spray them at high speed onto a surface, where they solidify and harden to form a concrete support layer. The wet shotcrete technique is simple, cost-effective, versatile, produces low dust emissions, and minimizes rebound, making it ideal for protecting the work environment, conserving materials, and improving the quality of the sprayed layer. It plays a significant role in various construction fields. In simple terms, it is equipment used for wet spraying.…

The tunnel wet shotcrete machine is one of the most effective tools for reducing dust, minimizing rebound, and saving materials in both domestic and international applications for tunnel construction. Wet shotcrete machines are widely used in engineering projects…

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.…
