Description
Technical field
The present invention relates to medium tunnel technical field, be specifically related to a kind of medium tunnel dust control by ventilation in work progress
Integrated system.
Background technology
Medium tunnel is in work progress, for ventilating in ensureing tunnel, it will usually arrange in tunnel by blower fan and airduct
The ventilating system constituted, thus provide enough oxygen for workmen.The subject matter existed is: (1) is for ensureing effect of ventilating
Really, airduct distance tunnel tunnel face is relatively near, is easy to damage in blasting process；(2) ventilate an only point, and ventilation effect is not
Preferable；(3), after explosion completes, tunnel passes through Natural Dust Suppression, at least needs half an hour, affects construction speed.
Summary of the invention
It is desirable to provide one both can guarantee that ventilation, again can effectively quickly depositing dust be exclusively used in medium tunnel construction
Ventilation depositing dust integrated system.
To this end, the technical solution adopted in the present invention is: a kind of medium tunnel dust removal by ventilation integrated system, including water cannon,
Blower fan and pneumatic hose, described assembling is at tunnel portal, and pneumatic hose is laid along bearing of trend level in tunnel in tunnel,
And be pneumatic hose air feed by blower fan, described water cannon is arranged in tunnel, and described pneumatic hose uses " y " shape afterbody, and " y " shape afterbody
Inside be cased with " y " shape tee T of matched hard, described " y " shape tee T include air intake breeches pipe, air-out water outlet breeches pipe and
Water inlet breeches pipe, air intake breeches pipe, air-out water outlet breeches pipe level be coaxially disposed, the termination of water inlet breeches pipe be provided with ring flange for water
The jet of big gun is connected, and water inlet breeches pipe is at an acute angle with air intake breeches pipe, intake rounding between breeches pipe and air-out water outlet breeches pipe so that
Yu Shuicong water inlet breeches pipe sprays into air-out water outlet breeches pipe smoothly, and described air intake breeches pipe, the diameter of air-out water outlet breeches pipe are pitched more than water inlet
The diameter of pipe.
Preferred as such scheme, described water cannon is arranged on the sidewall in tunnel, and water gun elevation is 60 ° and can be
Left-right rotation in the range of 180 °, assembling is on the sidewall of tunnel portal, and the setting height(from bottom) of pneumatic hose is more than 2.5m, optimizes
Installation site, is not take up normal construction region in tunnel.
Further, the termination of described air-out water outlet breeches pipe flushes with the afterbody of pneumatic hose, and air-out and water outlet are more smooth and easy.
It addition, the jet junction of described water inlet breeches pipe and water cannon is provided with sealing structure, it is to avoid connecting portion leaks
Gas leakage.
Beneficial effects of the present invention:
(1) distance of airduct distance tunnel tunnel face is determined by the water spray range of water cannon, and the range of usual small-sized water cannon is
30m 40m, the range of large-scale water cannon is about 100m, and the distance of traditional airduct distance tunnel tunnel face is 20m, sets up
After water cannon, the distance of airduct distance face increases, and saves the length of airduct, it is to avoid airduct damages in blasting process,
Extend the service life of airduct；
(2) afterbody of ventilation duct rotates with the rotation of water cannon, makes ventilation be become a face by a point, and ventilation effect shows
Write and improve；
(3), after explosion completes, tunnel utilizes the water cannon quick depositing dust of water spray, has saved the waiting time, has substantially increased construction
Progress.
