(system of high speed rail sound barrier)

Installation method ofsound barriers on highway and railway.

1. Mark the keel beaminstallation position on the high speed railway (expressway)

2. Install and fix the keelbeam

3. The distance between two beams is 500-600m

4. Install Aluminum foamsound-absorbing panel

5. Inset Aluminum alloy frame in order to fix the Aluminumfoam panel

6. Fix it to the beam with bolts

7. In order to prevent the bolts from loosening,install sturdy nuts.

*Precautions

1. Materials used for the high speedrailway (expressway) must be stainless steel or aluminum.

2. The specification of Aluminum foam sound-absorbing panelis adjustable as the design of high speed railway (expressway)

3. Color of Aluminum foam sound-absorbing panel can becustomized as required.




What is AluminumFoam?


Aluminum foam is a new concept metalmaterial which is foamed in sponge shape after melting aluminum ingot with various chemical ingredients and has many bubble layers inner structure.

Porous material is much lighterthan original one, which is the characteristic of porous. And, it improves the ability of  energy absorption and reduces the abilityof thermal and electrical conductivities than original metal materials. Inaddition, porous material has wide applications as well as excellent ability ofsound absorption and permeability of liquid, air, etc.

Aluminumfoam, a metal itself, can be applied to aerospace aviation required the  thermostability over 200℃. It is a 100%  recyclabl ecofriendly material and absolutely will not produceharmful substances no matter in the process of producing,  using or abandoning.




Main properties of aluminum foam


Ultra-light

Density is 0.2~0.4g/cm3 (Aluminium1/10,Iron1/30, and Wood 1/4)

Soundabsorption

Porous structure has a good soundabsorption.

Aluminum foam sound-absorbing materialcan be used in the inner decoration of buildings (walls, ceiling and floor),railway, highway, factories, mechanical equipment and any other fields.

Suitable for noisy place.

Non-flammability

100%non-flammability and no toxic gas released when burning.

Non-combustibility TEST verified to be qualified. <KIMM; IMO A.799 (19)>

I grade Non-flammability TEST ofaluminum foam surface verified to be qualified. <KICT; KS F2271>

Energyabsorption

Porous structure can effectively absorbenergy.

Have a great effect on energyabsorption after a high impact.

Firstly acquired the national SB5class (Guard rail shock-absorber)

Electromagnetic wave shielding ability

Aluminum foam has a function ofabsorbing electromagnetic wave

Widely used in military (stealth materials),TV station, hospital and any other electromagnetic shielding places.

Eco-friendly

100% recyclable Aluminum foam is nonpoisonous, odorless andharmless, no toxic gas released when burning.

Aluminum foam can be produced by recycled aluminum andits scraps.

Q:How is the sound barrier installed?
Sound barrier installation is the meaning of the road through the residential area is to reduce the noise on the surrounding residents and set up the impact of the road through the residential areas have to install the sound barrier design specifications have a range of influence can find out how much to how much Can be found within the range.
Q:How about the cooling tower sound barrier? What materials are used
You can use FRP combination transparent sound barrier Cooling tower sound barrier with a hybrid sound barrier, the top of the sound absorption unit, the following part of the sound insulation unit. Reasonable to determine the length and height of the sound barrier, you can get 10-25dB (A) of the noise reduction. Technical features: blinds with rain, moisture, sunscreen, antifreeze, dust, anti-corrosion, anti-strong wind and other functions. Sound absorption noise, the use of sound-absorbing material (for example: mostly made of porous material) or the use of sound absorption structure of the resonance structure (such as: metal or wood board perforation, after the cavity) to absorb sound energy is strong, Reduce noise. Sound absorption noise reduction is one of the important means of noise control, suitable for dealing with reflected noise. Power plant bending sound barrier arc noise barrier
Q:The best sound barrier manufacturers in China is that a few for the Olympic sound barrier engineering supplier is the enterprise
Beijing-Tianjin high-speed rail and Beijing-Shanghai are used. But the price is more expensive.
Q:What is the quality of the viaduct bridge?
the key is to set up your sound barrier for the area of the program design, the distance from the source of the noise source, the thickness of the plate, the type of sound barrier, and Height, etc.,
Q:Highway sound barrier manufacturers sound barrier price is how much
Affect the sound barrier price main factors: 1, sound barrier screen body selection of raw materials 2, sound barrier column specifications
Q:Sound barrier production qualification where to do
Rail Transit (Rail Transit) refers to the traffic volume, speed, safety, punctuality, protection of the environment, energy conservation and land use and other characteristics of the mode of transport, referred to as "rail", including subway, light rail, fast track, rail Trams and so on.
Q:High iron sound barrier column is made of I-shaped or H-shaped steel to do.
That is not to say with H-shaped steel can also be? The The To answer Yes. I-shaped steel strength is high, sound barrier column does not require high strength, with H-beam is reasonable.
Q:Combination sound barrier steel mold sound insulation effect
Sound insulation, height and length are two key, double sign highway combination of sound insulation as long as the road and the receiver can block the line of sight, at least you can reduce the volume of 5 dB, and each additional 1 meter, can reduce 1.5 dB
Q:High iron sound barrier bidding is how the baked?
He was doing business at the time, he stepped down, the competition is more intense, but each time the standard is not the same, every time before the iron construction tender with other companies to develop an exclusive standard, this is a bit too blatantly It!
Q:What are the classification of sound barriers?
Fourth, the composite sound barrier The composite sound barrier has the advantages of both transparent and opaque noise barriers. It is half of the resistive barrier barrier, the other half is a transparent sound barrier, from one and two composite from the above four kinds of sound barrier height can be freely combined according to design requirements, can also be customized according to customer requirements road screen.
