As shown in Figure 1, the tunnel dust removal method of the present embodiment comprises the steps of：
Step 100：One atomizing dust removal machine, atomizing are set respectively at one or more of tunnel source of dust releasing
Dust removal machine is sprayed in dust source.
Atomizing dust removal machine can select existing any spraying apparatus as needed.
In the case where source of dust releasing is a continuous panel region in tunnel, such as, the construction distance in tunnel it is longer and
Continuously, then a continuous panel region in tunnel all can sustained release dust, at this moment, atomizing dust removal machine is preferably a water
Curtain spraying device 10, cascade spraying device 10 can move back and forth in a panel region and can form one or more pieces mists
Curtain.
As shown in Fig. 2, cascade spraying device 10 includes：
Supporting rack 11, supporting rack 11 include a upper layer bracket 12 and two side stands 13, and two side stands 13 connect respectively
It is connected to the both ends of upper layer bracket 12 and is used to support upper layer bracket 12；
Host 14, host 14 are arranged on the side of side stand 13；
Multiple atomizers 15, multiple atomizers 15 are arranged at supporting rack 11；With
Two bases 16, two bases 16 are connected with two side stands 13 respectively, and two hosts 14 are respectively arranged at two
On base 16, the lower section of each base 16 is both provided with roller 17；
Wherein, supporting rack 11 is internally provided with interconnected multiple pipelines, and host 14 passes through pipeline and atomizer 15
Connection.
Host 14 is used to water pump being sent into multiple atomizers 15.
Upper layer bracket 12 can be made of more root long bars arranged side by side, and multiple atomizers 15 are set on every root long bar, in this way,
Cascade spraying device 10 can form multiple mist curtains.
During construction, cascade spraying device 10 is moved back and forth to prevent dust from expanding by roller 17 in a continuous panel region
Dissipate.
In the case where source of dust releasing is the dotted region in tunnel, such as, the job location in tunnel is only in tunnel
Some or some specific locations, the place for producing dust be discontinuous, at this moment, atomizing dust removal machine is preferably fog gun machine,
The fog gun machine can use commercially available fog gun machine.The alignment source of dust releasing spraying of fog gun machine.
Step 200：In tunnel, one group of cleaner is set every preset distance, cleaner includes an electrostatic precipitation
Air is pumped to electrostatic precipitator to cross air filtering by device and an extractor fan, extractor fan.
Being spaced a predetermined distance one group of cleaner as setting can be while tunnel internal operating environment is purified
Constructing tunnel operation provides sound ventilation environment.
Preset distance is preferably 100 meters -200 meters, more preferably 150 meters.150 meters of preset distance is chosen according to measure
Optimal spacing distance, with this interval setting cleaner, dust purification rate is preferable.
As shown in figure 3, the cleaner of the present embodiment is dedusting jet blower 20, dedusting jet blower 20 includes：Exhausting
