Description
Technical field
The utility model belongs to tunnel ventilation construction technical field, especially relates to a kind of tunnel airduct working vehicle.
Background technology
At present, the draft type that domestic and international construction ventilation of tunnel adopts pipeline forced mostly, outside hole, axial flow blower is set, fresh air is delivered to tunnel work face by coupled ventilating duct (i.e. flexible duct) by this axial flow blower, foul atmosphere in hole, under the squeezing action sending into fresh air in hole, drains into outside hole along the barrel excavated.When tunnel is longer, adopt multiple axial flow blower also, series connection mode to improve air quantity and air supplying distance.
But nowadays, when above-mentioned blower fan and ventilating duct are constructed, what the overwhelming majority all adopted is artificial construction's mode, for major long tunnel, site work amount is very large, needs first to install flexible duct and moves into place, again the airduct moved into place is fixed on piecemeal along on multiple airduct fixtures of longitudinal extension direction, tunnel laying, the required manpower and materials dropped into are many, take time and effort, had a strong impact on the efficiency of construction in tunnel.Thus, in practice of construction process, when existing tunnel construction flexible duct is installed, there is number of drawbacks and the deficiencies such as the manpower and materials of large, the required input of site work amount are more, efficiency of construction is low.In addition, in practice of construction process, flexible duct in tunnel is once after installation, and its position generally can not be moved easily, and flexible duct people is laid in the middle and upper part of side sidewall in tunnel usually, and the wind direction that such flexible duct is blown generally also immobilizes.
But during practice of construction, because explosion in hole is larger with the concentration of transporting blasting fume and the pernicious gas produced after explosion terminates, thus if adjust the mouth of pipe size of flexible duct, then can when air output be constant, the wind speed size of the flexible duct mouth of pipe is adjusted accordingly, thus the blasting fume near face and pernicious gas are discharged outside hole fast.Further, in practice of construction process, for meeting concrete ventilation requirement, the position of frequent needs to installation airduct adjusts temporarily, now needs to remove original airduct fixture, and reinstall airduct fixture on tunnel inside wall, waste time and energy, serious image constructing tunnel efficiency.Thus, nowadays a kind of structure is lacked simple, reasonable in design and use easy and simple to handle, that result of use is good tunnel airduct working vehicle, while normal ventilation, can adjust airduct caliber size, easy adjustment can be carried out to the installation position of installation airduct again.
