Description
Technical field
The utility model relates to the constructing tunnel air quantity controller, is specially a kind of construction ventilation of tunnel pipeline control for air distribution.
Background technology
In the constructing tunnel process, in order fresh air, the harmful dust concentration of dilution to be provided in the hole and to reduce environment temperature in the hole, palpus employing high-power blower to the air-supply of excavation operation face, is referred to as construction ventilation through pipeline.Constructing tunnel often adopts accessory channels such as inclined shaft, horizontal hole to increase positive hole excavation operation face, and utilizing a circuits is that two scope of operations provide ventilation simultaneously, abbreviates the one drag two air vent mode as.
The one drag two air vent mode; Mainly form by the connecting tube between high-power blower, trunk line, branch pipe(tube), master, the branch pipe(tube) (threeway) outside the hole etc.; Blower fan adopts tandem two-shipper unit more, can need according to air quantity in the hole, adopts unit air feed or two-shipper air feed; Main, branch pipe(tube) adopts flexible wind sleeve more, during ventilation under the effect of blast wind sleeve expand and form passage, blast disappears during shutdown, wind sleeve is sagging naturally.The trunk line diameter is generally 1.5～1.8m, and the branch pipe(tube) diameter is generally 1.2～1.4m; Connecting tube generally is connected firmly trunk line and branch pipe(tube).
During construction ventilation of tunnel; Be divided into intensified ventilation and continue the two kinds of citation forms that ventilate; When operations such as explosion, muck removal, sprayed mortar were constructed, work plane was seriously polluted, air worsens, and needs to adopt the intensified ventilation of big air quantity; In time the concentration of pernicious gas and dust in the dilution hole is improved the air quality condition of operating area; When other operation construction,, adopt the lasting ventilation of little air quantity, to satisfy the demand of constructor to fresh air owing to do not produce pollution.Intensified ventilation needs two blower fan air feeds, but the time is shorter, and lasting ventilation only needs single blower fan air feed, but the air feed time is longer.
All can open up two scope of operations simultaneously behind tunnel inclined shaft, the horizontal hole driving certain-length; Can artificially control and adjust the construction speed of two work planes,, cause to continue the waste of ventilation operation face air quantity when a work plane need continue to ventilate and another work plane when needing intensified ventilation; And the intensified ventilation face air volume is not enough; The intensified ventilation time lengthening influences the normal linking of operation, and wastes energy consumption, delay duration.
Summary of the invention
The utility model can not get reasonable distribution and causes ventilation time to prolong and the waste energy consumption, incur loss through delay the problem of duration in order to solve existing tunnel construction ventilation pipeline both sides work plane institute required airflow, and a kind of construction ventilation of tunnel pipeline control for air distribution is provided.
The utility model is to adopt following technical scheme to realize: construction ventilation of tunnel pipeline control for air distribution; Comprise tee junction; Tee junction bottom is provided with corresponding with its top sub position and to the cylindrical recesses of lower convexity; Be placed with the air quantity distribution drum in the groove; Air quantity distribution drum sidewall has four exhaust vents that are uniformly distributed with setting along its axis; The little air quantity exhaust vent that four exhaust vents are positioned on the same horizontal plane by axis and front and back are provided with, strong wind amount exhaust vent and about two apoplexy amount exhaust vents being provided with forms, air quantity distribution drum bottom centre is fixed with the rotating shaft that passes bottom portion of groove, is with the guide pipe that is fixed on below the bottom portion of groove in the rotating shaft; Rotating shaft below is connected with the control handle that rotates up and down around it, and the bottom portion of groove below is fixed with to be uniformly distributed with along its axis and is provided with and the fixing snap ring of four control handles corresponding with the exhaust vent position.
When construction ventilation of tunnel pipeline two work planes are lasting the ventilation; Adopt single blower fan air-supply; The apoplexy amount exhaust vent of rotation control handle to air quantity distribution drum is positioned at the left and right sides (and left and right joint one side of the tee junction in connecting branch road); Then control handle is stuck in control handle fixedly in the snap ring, prevents that the air quantity distribution drum is rotated by the effect of blast, guarantee that two work planes satisfy the needs that replenish fresh air.
When the either side of construction ventilation of tunnel pipeline two work planes carries out explosion, muck removal or sprayed mortar operation; Adopt two blower fan air-supplies; And the strong wind amount exhaust vent of air quantity distribution drum aimed at this work plane, little air quantity air outlet is aimed at the opposite side work plane, realizes that two work planes, one side intensified ventilation, opposite side continue the requirement of ventilating; Suitably reduce power of fan and dwindle the trunk line diameter, practice thrift the equipment input cost.
Gap location between the top sub inwall of air quantity distribution drum external wall of upper portion and tee junction is provided with rubber seal, under the effect of blast, forces rubber seal that air quantity distribution drum and tee junction is closely connected, reaches to prevent the purpose of leaking out.
The utility model reasonable in design is reliable; Realize the reasonable distribution of constructing tunnel one drag two ventilation both sides work plane institute required airflow, and can rationally adjust under the prerequisite of Design of ventilation, suitably reduced the power of ventilation equipment; The elasticity system that can realize the tunnel slope construction is simultaneously ventilated; Be the lasting ventilation of explosion, muck removal, the intensified ventilation of sprayed mortar operation period and other operation period, have economy, reasonable, energy-saving advantages, save equipment component acquisition expenses and daily energy consumption cost.
