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.
Compared to dry and semi-dry spraying methods, wet spraying has notable advantages, including less dust, reduced rebound, better protection of the work environment, material conservation, and improved quality of the sprayed layer. It is also easy to operate and maintain. Tunnel wet shotcrete machines are suitable for applications in places where plants are difficult to grow, such as rocky areas, hard soil, sandy soil, barren land, acidic soils, arid regions, and coastal embankments, for landscaping and greening purposes.
When spraying concrete, the tunnel wet shotcrete machine reduces dust concentration and rebound, increases the thickness of the main sprayed layer, improves production efficiency, and ensures quality control. One of its key advantages is its excellent sealing structure, which minimizes dust pollution. Additionally, during operation, the rebound is very low, which saves material. Since the concrete is mixed before spraying, the proper mix ratio is ensured, which guarantees the quality of the concrete.
The tunnel wet shotcrete machine is currently one of the best-performing support machines for anchor bolt spraying, with excellent dust-reduction, rebound-reduction, and material-saving properties. It is widely used in projects such as mining, sewer construction, foundation pit support, riverbank slope protection, and more. Apart from mining areas, it can also be used for irrigation, fertilization, pesticide spraying, soil treatment, and other routine care and soil improvement tasks. Furthermore, the tunnel wet shotcrete machine is also suitable for landscaping and greening in places where plants struggle to grow, such as rocky, hard soil, sandy soil, barren land, acidic soils, arid regions, and coastal embankments. It is used in highway slope greening, high-speed railways, mining reclamation, ecological restoration, desertification control, and other related projects.
