在地埋燃氣管道的管頂上方0.30.5米處設置警示帶，其作用為：

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

1、當開挖施工時，如挖到警示帶，則表示在下方0.30.5米處有燃氣管道，起到了警示和保護作用。

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、示蹤作用。尋找地埋燃氣管道時，找到警示帶即找到了管道。起到了示蹤作用。

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

3、現在的警示帶有示蹤線，利用測試儀器在不開挖的情況下，準確為管道定位。

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