公路声屏障的安装与路基一般以公路声屏障的使用路段来区分，其中路基段声屏障为一种形式，桥梁声屏障与高架桥为一种安装方式。路基段声屏障的安装与路基最为简单，声屏障立柱的各种受力等比较容易达到，也因此对于声屏障的高度方面限制较小，路基声屏障一般先做好预埋件基础，然后安装立柱，立柱安装之后开始安装声屏障的屏体，最后进行声屏障的调直。
The installation of highway sound barrier and subgrade are generally distinguished by the use of highway noise barrier, in which the sound barrier in subgrade section is a form, and the sound barrier of bridge and viaduct are a kind of installation method. The installation of the sound barrier in the subgrade section is the most simple, and the various forces on the column of the sound barrier are easy to reach. Therefore, the height of the sound barrier is limited. Generally, the foundation of the embedded parts for the sound barrier of the subgrade is prepared, and then the column is installed. After the column is installed, the screen of the sound barrier is installed, and finally the sound barrier is straightened.
