The main function of wet concrete spraying machines is to spray concrete onto the target surface through high pressure to form a protective layer or support structure. It is the core equipment in shotcrete construction and has been widely used in various shotcrete support projects. Let's take a look at the classification and application scenarios of wet concrete spraying machines.

　　1. Classification of wet concrete spraying machines

　　Common wet concrete spraying machines are usually divided into the following categories according to their working principles and application scenarios:

　　Hydraulic wet concrete spraying machine: This equipment is driven by a hydraulic system and generates high pressure through a hydraulic pump to spray the concrete mixture onto the construction surface. The hydraulic wet spraying machine has the characteristics of stable pressure and uniform spraying, and is suitable for large-area and long-distance spraying construction.

　　Rotor wet concrete spraying machine: This type of equipment adopts a rotor structure, and the concrete mixture is driven to be sprayed through the rotation of the rotor. The rotor wet spraying machine has a simple structure and is easy to maintain. It is often used in small and medium-sized projects and construction projects with special spraying requirements.

　　Vehicle-mounted wet concrete spraying machine: The vehicle-mounted equipment installs the wet concrete spraying machine on a vehicle, which has high mobility and is suitable for projects that require frequent movement of construction sites, such as municipal roads and bridge maintenance.

　　Concrete wet spraying manipulator: This is a highly intelligent device, usually equipped with a mechanical arm, which can accurately control the spraying direction and angle, and is suitable for projects with complex structures and fine construction, such as large tunnels and mining projects.

　　2. Application scenarios of wet concrete spraying machine

　　Concrete wet spraying machine plays an important role in multiple engineering fields:

　　Construction engineering: It is used for wall reinforcement, foundation construction and spraying of protective layers of buildings to improve the durability and stability of buildings.

　　Municipal engineering: In the construction and maintenance of municipal infrastructure such as roads, bridges, and underground pipelines, it is used to spray concrete to improve structural strength and corrosion resistance.

　　Railway and highway tunnels: In tunnel construction, wet spraying machines are used to spray concrete support layers to prevent landslides and ensure construction safety.

　　Foundation pit support: During the excavation of the foundation pit, wet spraying machines are used to spray concrete to form support walls to prevent foundation pit collapse.

　　Mining Engineering: In mining, wet spraying machines are used to spray concrete walls, protect mine structures, and ensure operational safety.

　　Slope management: In slope reinforcement projects, sprayed concrete forms a protective layer to prevent landslides and soil erosion.

　　As an important equipment in modern construction technology, wet concrete spraying machines have become an indispensable tool for various types of sprayed concrete projects due to their high efficiency, flexibility, and strong adaptability. With the continuous advancement of technology, wet concrete spraying machines will further improve construction efficiency and project quality, and provide more reliable technical support for building and infrastructure construction.
