Abstract
The utility model discloses ventilation installation in a kind of long tunnel hole, comprise the ventilation fan be positioned at outside hole, be positioned at tunnel store wind room.Separate ventilation machine in hole to storing wind room supply fresh air via inclined shaft wind band, stores in wind room and arranges 2 ventilation fans and supply fresh air respectively to main direction and assistant spiker direction, guides foul atmosphere direction to discharge outside hole from inclined shaft by jet blower.
Description
Technical field
The utility model relates to the ventilation installation in a kind of constructing tunnel.
Background technology
Construction ventilation is the important process matched therewith of tunnel, and ventilating, whether smooth and easy directly to affect constructor healthy, and existing method of ventilation is, arranges fixing ventilation fan, supply fresh air by press mode to the scope of operation outside hole.But this draft type to be leaked out the impact of factor because of pipe friction and pipeline, make the scope of operation required air air pressure away from tunnel portal can be significantly less than the quantity delivered of hole separate ventilation machine, for ensureing normally carrying out of construction, need to adopt the larger ventilation equipment of power to overcome wind loss on the way.For the ventilation fan that outlet wind-force is fixing, losing on the way for overcoming, sometimes needing to adopt special ventilation pipeline and a fairly large number of supporting facility to introduce tunnel depth.No matter adopt powerful device or special ventilation pipeline, all can cause a large amount of uses of the energy and material, increase construction cost and drop into.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly solves in tunnel depth hole air dirt and affect ventilation installation in the healthy hole of constructor.
For reaching above object, the utility model takes following technical scheme to be achieved:
Ventilation system in a kind of long tunnel hole, it is characterized in that, have an inclined shaft between described tunnel main direction with reciprocal assistant spiker direction and be communicated with tunnel, inclined shaft hole peripheral hardware hole separate ventilation machine, it is connected with the inclined shaft wind band in inclined shaft, this inclined shaft wind band is horizontally through tunnel, stretch to outside the tunnel one sidewall outline line of relative inclined shaft one closed store in wind room, be also provided with foul atmosphere in guide tunnel in inclined shaft and discharge the multiple stage jet blower outside inclined shaft hole; Described storing in wind room at least establishes ventilation fan in two holes, provides the fresh air in main direction in opposite directions and assistant spiker direction respectively by the opposing main hole wind band longitudinally arranged along Xu Feng room one, tunnel sidewall in tunnel.
In such scheme, described hole separate ventilation machine is one to two, and inclined shaft wind band quantity is consistent with hole separate ventilation machine quantity.
Described storing in wind room arranges independently transformer and runs for ventilation fan in hole.
Compared to existing technology, the utility model has the advantages that:
1, fresh air segmentation air feed, reduces ventilation fan power, saves power consumption.
2, when main direction and assistant spiker direction progress differ, guide wind direction by jet blower, eliminate the negative pressure of long end, ensure that the timely discharge of foul atmosphere.

Fig. 1 is layout schematic diagram of the present utility model.
In Fig. 1: 1, inclined shaft hole; 2, ventilation fan; 3, inclined shaft wind band; 4, wind room is stored; 5, ventilation fan in hole; 6, main hole wind band; 7, main direction; 8, assistant spiker direction; 9, transformer; 10, inclined shaft; 11, construction power supply pipeline; 12, fresh air; 13, foul atmosphere; 14, jet blower.
Detailed description of the invention
With reference to figure 1, the utility model comprises the hole separate ventilation machine 2 be positioned at outside inclined shaft hole 1, be positioned at tunnel store wind room 4; Store the expansion section in tunnel, wind room, the independent closed space namely formed beyond tunnel contour line.Hole separate ventilation machine 2 is connected with the inclined shaft wind band 3 in inclined shaft 10, and inclined shaft wind band is horizontally through tunnel and stretches into and store in wind room, provides fresh air to storing wind room; Multiple stage jet blower 14 is set in inclined shaft, is discharged outside hole from inclined shaft by the foul atmosphere 13 in jet blower guide tunnel.Store in wind room and arrange transformer 9 and run for ventilation fan 5 in hole, in hole, ventilation fan arranges 2, provides the fresh air 12 in main direction 7 in opposite directions and assistant spiker direction 8 respectively by opposing main hole wind band 6 in tunnel.Separate ventilation machine in hole is 1 or 2, and the quantity of inclined shaft wind band 3 is consistent with hole separate ventilation machine quantity.
Main hole wind band 6 is longitudinally arranged along Xu Feng room, tunnel sidewall, divides and is located at inclined shaft wind band 3 both sides.Inclined shaft wind band 3 and main hole wind band 6 can lay with flexible pipe.
Claims (3)
