The invention discloses a cooling and dust removal device and method for the internal environment of long-distance tunnel construction, comprising a water storage unit, a pressurizing unit and a spraying unit; Electric ball valve; the pressurizing unit includes a water pipe and a booster pump located on the water pipe; the spray unit includes a jet fan and a fan bracket; one end of the water pipe is connected to a flanged electric ball valve, and the other end is connected to the jet The water inlet of the fan is connected, and the water in the water storage tank is sent to the jet fan through the water delivery pipe through the booster pump for spraying. The cooling and dust removal device directly cools the construction section, requires less equipment and components, and has low engineering volume and investment cost; the nozzle combined with the automatic rotating device can cool the tunnel at multiple angles and long distances. Not only can it play a cooling role during operation, but the sprayed water mist can also significantly reduce the dust in the tunnel. |
