Although PE pipes have many advantages, their greatest weaknesses are low strength, poor light resistance, easy aging, and difficulty in detecting location, direction, and depth.

在以往市政建設施工中，由于管道的確切位置不十分清楚,被施工機械挖斷挖漏的現象很常見,由此造成的燃氣泄漏爆炸事故也時有發生,因此探測標地下PE管道的位置工作十分必要。

In the past municipal construction, due to the unclear exact location of the pipeline, it is common for the pipeline to be cut and leaked by construction machinery, resulting in gas leakage and explosion accidents. Therefore, it is necessary to explore the location of underground PE pipelines.

由于PE管材所具有的獨特技術性能和其他管材無法比擬的安裝方式,該種材料被全國燃氣行業廣泛應用于城市燃氣領域中，成為替代城市燃氣埋地鋼管、鑄鐵管道的理想材料，特別是輸送燃氣和自來水管道應用多。但另一方面,由于PE管

Due to the unique technical performance of PE pipes and the incomparable installation method of other pipes, this material is widely used in the field of urban gas in the national gas industry, becoming the most ideal material to replace buried steel pipes and cast iron pipes for urban gas, especially for gas transmission and tap water pipelines. On the other hand, due to the PE pipe

材的特殊性, PE燃氣管道在安裝、運行管理、探測定位上同樣存在特殊性。PE 管道為惰性材質制成,不

Due to the particularity of materials, PE gas pipelines also have particularity in installation, operation management, detection and positioning. PE pipes are made of inert material, not

導電.不導磁,埋人地下之后，目前還沒有較好的方法直接在地面探測到PE管道在地下的空間位置。

After conducting electricity and not conducting magnetism, and being buried underground, there is currently no better method to directly detect the spatial location of PE pipes on the ground.

為了PE管道埋地后能夠在地面探測到位置和埋深的問題，人們已經想出了多種方法,相比之下，導線示蹤線技術是經濟、效果的方法。

In order to solve the problem of detecting the location and depth of PE pipelines on the ground after they are buried, many methods have been devised. In contrast, the wire tracing technology is the most economical and effective method.

所謂導線示蹤線技術就是在鋪設施工PE管道時與PE管道-起埋人一- 條銅導線(簡稱示蹤線),為今后探測PE管道位置與深度所用,示蹤線法是目前國內外普遍采用的探測方法。示蹤線在埋地管道施工中，為了使示蹤線在以后能夠很好地起到示蹤作用,它的施工方法和探測方法選擇十分重要。

The so-called wire tracing line technology refers to a copper wire (referred to as tracing line) that is buried with the PE pipe during the laying and construction of PE pipes. It is used to detect the position and depth of PE pipes in the future. The tracing line method is currently widely used at home and abroad. In the construction of buried pipelines, the selection of construction methods and detection methods is very important in order to ensure that the tracer line can play a good tracking role in the future.
