在地埋燃气管道的管顶上方0.30.5米处设置警示带，其作用为：

Warning tape shall be set at 0.3-0.5m above the top of buried gas pipeline. Its functions are:

1、当开挖施工时，如挖到警示带，则表示在下方0.30.5米处有燃气管道，起到了警示和保护作用。

1. During excavation, if a warning tape is found, it means that there is a gas pipeline 0.3 to 0.5m below, which serves as a warning and protection.

2、示踪作用。寻找地埋燃气管道时，找到警示带即找到了管道。起到了示踪作用。

2. Tracing effect. When searching for buried gas pipeline, find the warning tape and find the pipeline. It plays a tracer role.

3、现在的警示带有示踪线，利用测试仪器在不开挖的情况下，准确为管道定位。

3. Now the warning has a trace line, and the test instrument can accurately position the pipeline without excavation.
