地埋燃氣管道示蹤線是指埋在地下的燃氣管道上方一定深度處的特殊線材，可以通過探測儀器檢測到，起到標識燃氣管道位置和方向的作用。

The underground gas pipeline tracer line refers to a special wire buried at a certain depth above the underground gas pipeline, which can be detected by detection instruments and plays a role in identifying the position and direction of the gas pipeline.

地埋燃氣管道示蹤線作為一種保障措施，可以幫助燃氣公司和施工方快速、準確地確定燃氣管道的位置和走向，避免無意中破壞燃氣管道，同時也便于燃氣管道的維修和改造。

As a safety measure, buried gas pipeline tracing line can help gas companies and construction parties quickly and accurately determine the position and direction of gas pipelines, avoid unintentional damage to gas pipelines, and also facilitate the maintenance and renovation of gas pipelines.

地埋燃氣管道示蹤線根據材料的不同可以分為鋁帶、鋼帶、銅線等幾種。其中鋁帶是目前應用廣泛的示蹤線，具有導電性好、壽命長、低等優點，受到廣大用戶的青睞。

The tracer line for buried gas pipelines can be divided into several types based on the material, such as aluminum strip, steel strip, copper wire, etc. Aluminum strip is currently a widely used tracer line, which has advantages such as good conductivity, long service life, and low price, and is favored by a large number of users.

施工地點應在燃氣管道埋深0.5-0.8米處，示蹤線要緊貼燃氣管道固定，鋁帶示蹤線應采用接頭連接，接頭要包覆在保護管中并進行防腐涂層處理，以防止接頭生銹導致示蹤線斷裂。

The construction site should be at a buried depth of 0.5-0.8 meters in the gas pipeline, and the tracing line should be fixed tightly against the gas pipeline. The aluminum strip tracing line should be connected by joints, and the joints should be wrapped in protective pipes and treated with anti-corrosion coatings to prevent rusting of the joints and breakage of the tracing line.

隨著城市的不斷發展和改造，地下管道也隨之增多，其中包括大量的燃氣管道。在進行地下燃氣管道施工及改造工程時，必須使用地埋燃氣管道示蹤線進行標識，以避免因操作不當或施工誤差導致燃氣管道被破壞，給人員和道路帶來隱患，造成不必要的損失。

With the continuous development and renovation of cities, underground pipelines have also increased, including a large number of gas pipelines. When carrying out underground gas pipeline construction and renovation projects, it is necessary to use buried gas pipeline tracing lines for identification to avoid damage to the gas pipeline due to improper operation or construction errors, which may cause safety hazards to personnel and roads and cause unnecessary losses.
