It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments creates.
A kind of Tunnel Blasting sound insulation and noise reduction door, as shown in Figures 1 to 3, including door curtain soft in the middle part of outer framework 1, outer framework 1
The weight body 3 that body 2 and 1 bottom of outer framework are set；The outer framework 1 is in " mouth " font structure, is equipped between its opposite both sides
It is some to strengthen rope 4；The door curtain body 2 is equipped with some air holes 5, is equipped with each air hole 5 and anti-raises one's hat 6；It is described anti-
Raise one's hat and be equipped with filter element 7 in 6.The connecting hole for being used for fixing this sound insulation and noise reduction door, or other connectors are equipped with outer framework,
Easily outer framework can be fixed on the inner wall in tunnel.In general, porous foam acoustical cotton can be set for side in door curtain body,
Noise can effectively be adsorbed.
In an optional embodiment, above-mentioned reinforcement rope 4 is embedded in door curtain body 2, its both ends is separately fixed at outline border
On frame 1.Strengthen rope combined with door curtain body it is firm, can auxiliary door curtain resist blasting impact well.
In another optional embodiment, above-mentioned reinforcement rope 4 is in the door curtain body 2 towards one on the outside of tunnel portal
Face, equivalent to door curtain body has been caught, when door curtain body is subject to blasting impact wave impact, can be good at supporting using rope is strengthened
Door curtain body, prevents door curtain body from producing excessive deformation, or deformation is excessive causes to damage.
It is pointed out that strengthening rope preferably uses pancake structure, the plane where its width connects with door curtain body
Touch, when door curtain body is hit, curtain produces stop to flat reinforcement rope on the door, increases the contact area with door curtain body, keeps away
Exempt to damage door curtain body.In addition, the adjacent two reinforcement rope is arranged in a crossed manner, stability is more preferable.
Above-mentioned weight body 3 is refilling type structure, including is fixed on the counterweight casing 8 of 1 lower end of outer framework, in counterweight casing
Filler is filled with 8, feeding port 10 and outlet 11 are equipped with counterweight casing 8.When manufacturing this sound insulation and noise reduction door, only
Counterweight casing need to be set in outer framework lower end, and the filler in counterweight casing can be at the scene using this sound insulation and noise reduction door
Loaded.Filler can select the liquid such as rubble, sandy soil or water, be loaded by feeding port, very convenient.It is real being not required
During with this, filler can be discharged by outlet, facilitate folding, transfer and transport.
It should be noted that setting weight body in outer framework lower end, it is hit primarily to improving this sound insulation and noise reduction door
When stability, preferably improve impact resistance using weight body, be unlikely in explosion, blasting impact power is open-top by door.
Above-mentioned door curtain body 2 is made of nylon fiber, still, do not limit to nylon fiber material, can also use other
The high flexible material of impact resistance, intensity, its each side are fixed with corresponding outer framework respectively.When guarantee is hit, door curtain body is not
It can be pushed out.And door curtain body uses impact-resistant soft nylon fiber material, it can be ensured that when being hit, itself have certain
Retractility, will not be crashed to pieces, as door curtain body expands outwardly, shock wave also form good cushioning effect, reduce
Noise of blasting.It should be noted that door curtain body is made of flexible material, when door curtain body withstands shocks ripple, its medium position to
Displacement on the outside of hole is greater than the displacement of surrounding and outer framework junction, therefore, causes middle " depression ", shock wave
Caused air-flow is influenced by this " depression ", can partly be turned back along depression inner wall, equivalent to " reflection " or " refraction " into hole
Portion, effectively reduces outside noise transmission to hole.
It is above-mentioned it is anti-raise one's hat 6 it is overall be in " convex " type structure, the larger one end of its outside diameter is on the inside of door curtain body 2, it is towards door
The end face of the path one end in outside does not protrude from the external side surface of door curtain, avoids interference with, and prevents from raising one's hat and is damaged or taken off by scraping collision
Fall；The filter element 7 be arranged on it is anti-raise one's hat 6 hollow cavity in.Anti- by setting is raised one's hat, and is maintained well inside it
Filter element, will not be hit wave impact and come off, in tunnel shock wave can part be discharged to by air hole outside hole, energy
Effectively reduce the impact force that door curtain body is born, and reliable sound insulation and noise reduction effect of getting back.
Anti- 6 both ends of raising one's hat are equipped with end cap, and the inner end cap 12 towards hole inner side (i.e. the larger side of outside diameter) can be spiral shell
Line, which is connected to, to be prevented raising one's hat on body 13 or being buckled in preventing raising one's hat on body, to facilitate the filter element inside handling；And
The outer end cap 9 of (i.e. the smaller side of outside diameter) can be with preventing body integral structure of raising one's hat, on the end cap on the outside of towards hole
Equipped with some exhausting-gas holes, avoid being hit and falling off, avoid influencing using effect, also prevented security risk.
In order to avoid noise straightline propagation, exhausting-gas hole that can be set on each anti-outer end cap of raising one's hat is set in oblique
Hole, when processing exhausting-gas hole, exhausting-gas hole is made slanting, prevents noise straightline propagation in tunnel.And exhausting-gas hole incline direction
It is preferably provided to upward, noise in tunnel be arranged to aerial diffusion, effectively reduces noise pollution.
Above-mentioned filter element 7 is filter screen or active carbon particle.Filtering is can be very good to be discharged to outside tunnel portal
Gas, avoids pollution environment.
The invention is simple in structure, and design is reasonable, by the effective sound insulation and noise reduction of door curtain body, and has good buffering
Ability, corresponding door curtain body, which is provided with, to be strengthened restricting, and the ability that door curtain body bears active force under complex working condition is enhanced, when being hit
It is not easy to damage, service life length.Meanwhile be equipped with door curtain body and can make the air hole that impact air-flow passes through, allow a part
Impact is discharged along air hole, alleviates door curtain body impact force.Whole sound insulation drop is ensure that well using outer frame body and weight body
Make an uproar the stability of door.
The foregoing is merely the preferred embodiment of the invention, is not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on, should be included in the invention
Protection domain within.
