Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further:
As Figure 1-Figure 4, the traffic route monoblock type non-metal sound barrier of primary concreting molding, by some sound separating members
Unit group forms side by side, and sound separating member unit group is made up of side by side two sound absorbing-insulating body units, and sound absorbing-insulating body unit includes two
Root wind-resistant column 1, is provided with sound absorbing-insulating body 2 between two wind-resistant columns 1, be provided with some sound absorption body openings 4 in sound absorbing-insulating body 2, inhales
Sound body opening 4, built with sound absorber, the one side of sound absorbing-insulating body 2 has some sound-absorbing hole 3, wind-resistant column 1 and sound absorption
