Let's discuss the analysis of highway sound barrier processing technology
As everyone knows, what is the highway sound barrier processing technology? Highway sound barriers can be used for highways or other sites. As long as there is noise, you can see it.
At present, there are the following problems and deficiencies in the application of road noise barriers: aerodynamic noise and the interaction between aerodynamic (train wind) generated by fast vehicles, especially rail trains, and the waterproof layer noise barrier walls, which endanger the building structure and noise control, and can reduce the noise reduction effect. The structure of the noise barrier cannot be adjusted according to the actual situation.
The processing technology of highway sound insulation materials is more prominent. They have a certain UV blocking effect, and even after being treated with new technology, the entire durability board surface also has special technology, and the product value is stable to ultraviolet rays. These products have a longer service life. After long-term use. It can maintain the optical properties of all new products and is not subject to ultraviolet light or other conditions. Therefore, these materials can be used for a series of other buildings and are more suitable for the application of advertising products.
The production process of highway sound barriers is relatively light. Compared with the thickness of ordinary 1/12 glass, the solid board inside is 1/2 the thickness of the glass. Because the quality of all raw materials is very light, and it is not easy to break during actual processing, it can better highlight its own installation characteristics, and can even effectively save assembly costs.
Analyze whether the larger the highway sound barrier, the better the sound insulation
An object protected by a highway sound barrier is higher than the height of the sound barrier. If the protected object is lower than the height of the sound barrier, the effect of the sound barrier is better. For example, the sound barriers of foreign expressways have good protection effects on detached villas, and the sound barriers protect the objects rather than the sound barriers themselves. It is not suitable to use noise reduction barriers to form urban environmental noise in the interchange bridge. In this case, the use of effective measures such as windows and doors in buildings is both economical and reasonable. Soundproof windows also allow for good ventilation and have achieved good results.
This method confirms the barrier height. After years of design and scientific research experience, the sound barrier can have an OK "reasonable working frequency". Here, the concept of reasonable working frequency LGR; E represents the number of times the sound barrier is attenuated, or the sound level working frequency of 1/3 octave band 3. If the noise wavelength is lower than the "reasonable working frequency" of long-wave transmission, and transmission is in the sound insulation effect, the sound barrier may not be large. Because of the long-term existence of the noise wavelength of the "reasonable working frequency", the sound barrier has a good sound insulation effect.
With the rapid development of highway networks in dealing with environmental noise problems of sound barriers, at present, it has been increasingly used. However, the sound barriers built in China at present are not good, causing unnecessary waste to the people. The reason is that the design of most sound barriers lacks scientific basis and is very blindly following the trend. Under appropriate circumstances, setting sound barriers, and how the length, height, and other parameters of the sound barrier are determined by cognition.
