聚乙烯（PE）管道因其施工方便、对输送物质污染小以及工程造价相对减少等优点，在国内埋地管道施工中已经广泛应用。但与钢管比较，强度低是其大的弱点。

Polyethylene (PE) pipeline has been widely used in domestic buried pipeline construction because of its advantages such as convenient construction, little pollution to transported substances and relatively reduced project cost. However, compared with steel pipe, low strength is its major weakness.

目前结合以往燃气管道施工，由于各种因素管道的埋地位置无法准确掌握，遇到其他市政管线施工时PE燃气管道被第三方施工机械挖断、挖漏的现象比较频繁，严重的将会造成燃气泄漏爆炸事故，因此在施工中使用PE燃气管道示踪线以及借此探测燃气管道埋深及管位具有重要意义。

At present, in combination with the previous gas pipeline construction, due to various factors, the buried position of the pipeline cannot be accurately mastered, and the PE gas pipeline is frequently cut and leaked by the third party construction machinery during the construction of other municipal pipelines, which will cause gas leakage and explosion accidents in serious cases. Therefore, it is of great significance to use the PE gas pipeline tracing line in the construction and to detect the buried depth and pipe position of the gas pipeline.

通过资料了解，PE燃气管道属惰性专用混配料制成，不导电、不导磁，具有较强的耐腐蚀性能，在一个时段内管道埋地施工完成后，还没有较好的方法直接在地面探测到已施工PE燃气管道的埋深及地下的空间位置。

According to the data, PE gas pipeline is made of inert special mixed materials, which is non-conductive, non magnetic, and has strong corrosion resistance. After the buried construction of the pipeline is completed within a period of time, there is no good method to directly detect the buried depth of the constructed PE gas pipeline and the underground space position on the ground.

为了PE燃气管道埋地后便于地面探测管位和埋深的问题，在施工中运用了示踪线法，使其与PE燃气管道随管固定敷设，为今后探测PE管道位置所用，此种方法也是现阶段国内外普遍采用的探测方法。

In order to solve the problem that the PE gas pipeline is easy to detect the pipe position and buried depth on the ground after being buried, the tracer line method is used in the construction to make it fixed with the PE gas pipeline, which is used to detect the PE pipeline position in the future. This method is also a commonly used detection method at home and abroad at this stage.

在埋地PE燃气管道施工中，如何保证新建管道以及已通气管道的和不被第三方破坏，发挥示踪线的作用，那么示踪线的管位探测方法和随管敷设方法将显得尤为重要。您有购买需求的话就来我们网站http://www.lnszgh.com咨询了解吧！

In the construction of buried PE gas pipeline, how to ensure the safety of the new pipeline and the aerated pipeline from being damaged by the third party, and how to play the role of the tracer line, then the pipe position detection method and the laying method along the pipeline of the tracer line will be particularly important.
