When sound waves encounter sound barrier, reflection occurs during propagation, transmission and diffraction three phenomena. Direct sound barrier can prevent the spread of plug-in sound barriers, and the attenuation of the transmitted sound enough, while transmitting the sound effects are negligible. Therefore, sound effects sound barrier is generally the amount of noise reduction can be said that it reflects the sound through the sound barrier to shield the two skills. Between the sound source and the receiving point to insert a sound barrier sound barrier, set up barriers infinite louver hole sound barrier, sound waves can last from above the diffraction barrier, and in the subsequent formation of an acoustic shadow zone semi-enclosed sound barrier, as light is obscured by objects that form a shadow. In this acoustic shadow area, people can feel the noise significantly reduced, and this is the sound barrier noise reduction. Highway sound barrier construction methods: 1. railway infrastructure construction sequence sound barrier projects: Loft leveling → → hand-dug Section Wall formwork pouring hole → → digging Section pile formwork pouring Section Wall → circulation to the design depth → → reaming pile bottom hole cleaning, inspection holes on the back cover of concrete pouring → → → inspection dipping steel cage reinforced concrete pour → → maintenance.
