Description
Technical field
The utility model belongs to sound barrier technical field, and in particular to a kind of spliced road sound barrier.
Background technology
At present, sound absorbing-insulating barrier is gone directly sonic propagation for absorbing and isolating noise source, noise source and recipient it
Between the sound absorption that sets and sound insulation shielding harness, it makes recipient be placed in acoustic shadow, has preferably to sonic propagation of wherein making an uproar
Isolation effect.The rapid development of present high-speed railway generates substantial amounts of noise pollution, and sound barrier takes up an area less, easy to manufacture and install
Fast, construction investment is suitable, it has also become the important measures of traffic noise pollution control.
In communication process, running into sound barrier can reflect, project and three kinds of phenomenons of diffraction sound wave.Usually it is considered that
Sound barrier can prevent through sonic propagation, and system be made to penetrate sound have enough attenuation, and the influence of projection sound can be ignored.
Therefore, noise abatement amount generally may be employed to represent in the sound absorption effect of sound barrier, and it is saturating that it reflects the shielding of sound barrier above two
The ability of sound.A sound barrier is inserted between sound source and receiving station, if sound barrier endless, sound wave can only be from the top of barrier
Diffraction is gone over, and formed behind an acoustic shadow just as light is obscured by an object to form a shade.In this sound shadow
In area, people can feel that noise substantially reduces, and here it is the noise reduction effects of sound barrier.It is inserted between sound source and recipient
One facility makes Acoustic Wave Propagation there are one significant additional attenuation, so as to weaken the noise in the certain area where recipient
It influences, such facility is referred to as sound barrier.The sound barrier has been widely used in countries in the world, especially high-speed iron in recent years
The rapid development on road, various countries have also carried out high speed railway sound barrier many research, high speed railway sound barrier design with
It also conducts in-depth research in terms of construction and largely puts into practice.
Road sound barrier noise reduction of the prior art is bad, and installs complex, and dismounting is cumbersome and existing
Sound barrier be typically all straight panel shape, running into curved section needs in addition curved sound barrier customized, influences efficiency.
Utility model content
The purpose of this utility model is to provide a kind of spliced road sound barrier, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical solution：A kind of spliced road sound barrier, including base
Seat, the upper end of the pedestal is fixedly connected with shield plates, fixed column, the fixed column is fixedly connected on the right side of the shield plates
Be internally provided with post holes, the left side top of the shield plates is fixedly connected with connecting rod, and the left end of the connecting rod is fixedly connected
There is swingle, the lower end of the pedestal is fixedly connected with built-in fitting.
Preferably, the shield plates include the PVC hardboards of front and back and the fiberboard at middle part, the PVC hardboards
Inside is fixedly connected with rock cotton board, and acoustical cotton is filled between the rock cotton board and fiberboard.
Preferably, the barrier plate surface is equipped with reflection protrusion.
Preferably, the diameter of the swingle is smaller 0.2cm-0.5cm than the diameter of post holes.
Preferably, the surface of the post holes is equipped with graphite linings.
Preferably, it is in 120 ° of angles between the downside of the reflection protrusion and shield plates.
The technique effect and advantage of the utility model：The spliced road sound barrier, by between post holes and swingle
Connection, so that can be rotated between each piece of sound barrier with certain angle, so as to adapt to curved road surface；It is logical
Cross the sound insulation of rock cotton board, acoustical cotton and fiberboard so that the noise inside highway is largely isolated or absorbs, and increases noise reduction
Effect；The utility model is designed reasonably, suitable for producing and promoting and applying.
