聚乙烯（PE）管道因其施工方便、對輸送物質(zhì)污染小以及工程造價相對減少等優(yōu)點，在國內(nèi)埋地管道施工中已經(jīng)廣泛應(yīng)用。但與鋼管比較，強度低是其大的弱點。

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.

目前結(jié)合以往燃氣管道施工，由于各種因素管道的埋地位置無法準(zhǔn)確掌握，遇到其他市政管線施工時PE燃氣管道被第三方施工機械挖斷、挖漏的現(xiàn)象比較頻繁，嚴(yán)重的將會造成燃氣泄漏爆炸事故，因此在施工中使用PE燃氣管道示蹤線以及借此探測燃氣管道埋深及管位具有重要意義。

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.

通過資料了解，PE燃氣管道屬惰性專用混配料制成，不導(dǎo)電、不導(dǎo)磁，具有較強的耐腐蝕性能，在一個時段內(nèi)管道埋地施工完成后，還沒有較好的方法直接在地面探測到已施工PE燃氣管道的埋深及地下的空間位置。

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.

為了PE燃氣管道埋地后便于地面探測管位和埋深的問題，在施工中運用了示蹤線法，使其與PE燃氣管道隨管固定敷設(shè)，為今后探測PE管道位置所用，此種方法也是現(xiàn)階段國內(nèi)外普遍采用的探測方法。

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燃氣管道施工中，如何保證新建管道以及已通氣管道的和不被第三方破壞，發(fā)揮示蹤線的作用，那么示蹤線的管位探測方法和隨管敷設(shè)方法將顯得尤為重要。您有購買需求的話就來我們網(wǎng)站http://www.tjshouche.cn咨詢了解吧！

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.
