Industrial nozzles are also widely used in Metro construction.

As we all know, when the subway is built, a lot of soil will be excavated. For the sake of urban cleanliness and environmental protection, the dregs truck transporting these soil can only start transporting after 8:9 p.m., and usually stop transporting at 5:00 a.m. The excavated soil needs to be accumulated for nearly 20 hours. If not treated, the dust will disperse in hot weather and spread throughout the city. Everywhere.

Using dust spray nozzle to spray soil can effectively inhibit the diffusion of dust, which can not only keep the city clean and environmental protection, but also provide a good working environment for the subway staff.

For muck trucks, it is necessary to wash the wheels in addition to soil spray or spray before carriage. Wheel washer is produced in response to the construction site type of dregs transport vehicle.

After loading the soil, the dreg truck drives into the wheel washer area, and the wheel is washed automatically or manually (according to the setting of the operation switch). The core of washing machine washing is to use single fluid nozzles, fan shaped or conical nozzles, hydraulic pressure and spray to wash the wheels. After the wheels are washed, they can drive into the city lane for operation.

The application of industrial nozzles in metro construction may have other aspects, because there is no in-depth understanding of shield tunneling, so it will not be elaborated for the time being.
