Description
Technical Field
The invention relates to the technical field of tunnel construction, in particular to a movable ventilation purification device for drilling and blasting construction of an ultra-long highway tunnel.
Background
The construction of the road tunnel is usually carried out by adopting a drilling and blasting method and is carried out along with fuel machinery and vehicles. Under the relatively closed environment in the tunnel, the generated fuel oil tail gas and blasting smoke dust are difficult to naturally dissipate, and in order to ensure the healthy breathing of workers in the tunnel, the dirty air in the tunnel needs to be discharged and fresh air needs to be fed. The traditional tunnel construction ventilation method comprises the following steps: an axial flow fan is arranged at the hole, fresh air is pressed in from the outside of the hole and is delivered to the face of the palm through a soft air pipe, and dirty air is discharged out of the hole from the hole along the main hole. This approach has the following drawbacks: firstly, the dirty air is discharged out of the tunnel in a pressure mode, the number of the axial flow fans is large, the power of the axial flow fans is high, the energy consumption is high, and in addition, the external environment of the tunnel opening is polluted to a certain extent; the construction ventilation method is only suitable for a tunnel with the single-head tunneling length not more than 2000m, and when the tunneling length is too large, the air volume and the air pressure loss of the air supply pipe are too large, so that the ventilation efficiency is reduced. Especially, when blasting on the tunnel face, in order to avoid the blast pipe from being damaged by blasting impact, the blast pipe is generally required to be stopped and the blast pipe with the front end of dozens of meters is removed; after blasting, the air pipe is manually connected to a position 20-30 m away from the face of the tunnel in severely polluted air, and then an axial flow fan is started to supply fresh air to the face of the tunnel. The time consumed by re-ventilation is generally more than half an hour, and more than one hour, the operation condition can be barely achieved; and along with the increase of the tunneling length, the longer the time for repeatedly disassembling and connecting the air pipes is, the lower the ventilation efficiency is, and the worse the working environment is. Although the length of the blast pipe can be increased by adding the relay fan, the single-head tunneling distance of 3000m is difficult to break through under the existing engineering equipment and technical conditions. In addition, the dirty air advancing path penetrates through the whole excavated cavity space and is discharged from the cavity opening, so that the whole tunnel is in continuous secondary pollution. It can be seen that the traditional ventilation mode has the disadvantages of more material consumption, high labor intensity, low ventilation efficiency, high construction cost, long construction period and high construction difficulty.
