地埋燃气管道示踪线是指埋在地下的燃气管道上方一定深度处的特殊线材，可以通过探测仪器检测到，起到标识燃气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.

地埋燃气管道示踪线作为一种保障措施，可以帮助燃气公司和施工方快速、准确地确定燃气管道的位置和走向，避免无意中破坏燃气管道，同时也便于燃气管道的维修和改造。

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.

地埋燃气管道示踪线根据材料的不同可以分为铝带、钢带、铜线等几种。其中铝带是目前应用广泛的示踪线，具有导电性好、寿命长、低等优点，受到广大用户的青睐。

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.

施工地点应在燃气管道埋深0.5-0.8米处，示踪线要紧贴燃气管道固定，铝带示踪线应采用接头连接，接头要包覆在保护管中并进行防腐涂层处理，以防止接头生锈导致示踪线断裂。

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.

随着城市的不断发展和改造，地下管道也随之增多，其中包括大量的燃气管道。在进行地下燃气管道施工及改造工程时，必须使用地埋燃气管道示踪线进行标识，以避免因操作不当或施工误差导致燃气管道被破坏，给人员和道路带来隐患，造成不必要的损失。

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.
