Problems solved by technology
[0002] In tunnel construction, the concentration of dust generated in the tunnel after blasting is very high, and the dust reduction efficiency of natural settlement is low. Operators in the next process have to wait for a long time after blasting to enter the tunnel face for construction. The waiting process has greatly affected the progress of the tunnel construction
The traditional dust suppression method also includes using the air intake system to supply air for dust reduction, but the dust suppression effect of the air supply is limited, and the dust concentration near the tunnel face cannot be effectively reduced. Lining trolleys conflict with each other, affecting the progress of tunnel construction

The invention discloses a rapid dust removal system for tunnel blasting. The rapid dust removal system involves a tunnel sealing trolley, a high-pressure air supply unit and a dust removal device, wherein the tunnel sealing trolley of the rapid dust removal system is arranged at the front end of an inverted arch lining, the tunnel sealing trolley seals a tunnel face operation area, and a sealed dust removal area is formed; an air compressor unit in the high-pressure air supply unit is arranged outside a tunnel hole, booster fans are arranged on the tunnel sealing trolley, and a high-pressure air supply pipe connected among the booster fans of the air compressor unit is arranged in a tunnel cable trough; the inlet end of an air supply hose is connected with outlets of the booster fans and supplies air towards the tunnel face, so that reflection airflow from the tunnel face to the side where the tunnel sealing trolley is located is formed in the dust removal area; the dust removal deviceis arranged on the tunnel sealing trolley, an exhaust opening of the dust removal device is located in the side facing the tunnel face, and an exhaust opening is located in the other side opposite tothe exhaust opening. According to the rapid dust removal system for the tunnel blasting, the tunnel dedusting efficiency can be improved, the conflict between an original air supply pipe and a tunnelsecondary lining trolley workshop is eliminated, and the construction progress is guaranteed.
Description
technical field [0001] The invention relates to the field of tunnel construction, in particular to a fast dust removal system for tunnel blasting. Background technique [0002] In tunnel construction, the concentration of dust generated in the tunnel after blasting is very high, and the dust reduction efficiency of natural settlement is low. Operators in the next process have to wait for a long time after blasting to enter the tunnel face for construction. The waiting process has greatly affected the progress of the tunnel construction. The traditional dust suppression method also includes using the air intake system to supply air for dust reduction, but the dust suppression effect of the air supply is limited, and the dust concentration near the tunnel face cannot be effectively reduced. Lining trolleys conflict with each other, affecting the progress of tunnel construction. Contents of the invention [0003] In order to avoid the shortcomings of the above-mentioned pri...
