The foundation pit support shotcrete machine uses compressed air to spray the concrete mixture on the shotcrete surface in a certain proportion and at a certain speed to form a concrete support layer. In recent years, shotcrete technology is widely used in construction, railway tunnels, mine shaft construction, slope reinforcement and other fields because of its simple process, unique construction effect, economic and rapid construction.

The shotcrete shotcrete machine is a shotcrete machine, which is widely used in shotcrete construction operations in mines, tunnels, culverts, subways, hydropower, underground engineering and coal high-concentration mine roadways, and is widely used in shotcrete construction operations in mines, tunnels, culverts, subways, hydropower, underground engineering and coal high-marsh mine roadways. Various types of wall reinforcement grouting fine aggregate concrete.

The foundation pit support shotcrete machine is an electric screw type high-pressure mortar spraying machine with advanced technology, simple operation and no special training. 1: Functional diversification, can be sprayed mortar cement, fire and temperature resistant materials, dry powder, putty and other materials. 2: uniform spraying amount, stable power, no intermittent pulse phenomenon, so that the project to ensure. 3: The spraying adhesion is strong and the slurry will not fall off and the slurry will not flow. 4: The reasonable and humanized design makes the machine beautiful and practical, and it is convenient for one person to move back and forth. 5: The practical machine can not only greatly shorten the construction period, save time and labor, but also avoid the cost and time of scaffolding. 6: The workload of spraying 150 ㎡ per hour can replace the workload of more than a dozen workers every day, save at least 2000 yuan in labor costs. 7. The connection between spraying and feeding pipe can be made. The yin and yang corners and roof can be sprayed. It is convenient to operate the mortar spraying machine. The mixed cement mortar is filtered through a vibrating screen. Let the bone slurry with a diameter of less than 6MM enter the spraying machine; It is transported to the nozzle through the pipeline. With the help of compressed air, the slurry is continuously and evenly sprayed on the construction work surface to finish painting the decorative surface.

Technical characteristics of the foundation pit support shotcrete machine.

The through rotor type non-bonding material cavity, the material is unobstructed, effectively saving time.

Low pressure, low-speed swirling wind, thin flow transportation, uniform and stable material flow, high spray layer strength.

Four-point elastic compensation clamping, good sealing effect, less dust sticking beside the machine, and long life of vulnerable parts.
