Concrete wet spraying machine used in the construction of concrete support engineering

Concrete wet spraying machine used in the construction of concrete support engineering

Issue Time:2022/11/08
Shotcrete machine is the core equipment in shotcrete construction, and is widely used in related shotcrete support projects such as construction, municipal administration, railway and highway tunnels, foundation pits, mines, and slopes. With the rapid development of underground spaces such as highway and railway tunnels, urban subway tunnels, and mining resources, the demand for concrete shotcrete is increasing.

According to the different construction techniques of shotcrete, common concrete shotcrete machines are generally divided into two categories: concrete dry shotcrete machine and concrete wet shotcrete machine, which are respectively used in dry spraying process and wet spraying process. With the improvement of wet spraying equipment and wet spraying process and the continuous improvement of construction requirements, concrete wet spraying machine has become the mainstream equipment for concrete spraying.

The working principle of the concrete wet spraying machine is to use hydraulic pressure to transport the ready-mixed mixture to the nozzle through the pipeline, then introduce compressed air and accelerator at the nozzle, and then spray the mixture on the sprayed surface at a high speed to quickly set. Form a concrete support layer.
