隨著PE管道大量應用，管道的定位和日常維護日益重要，現在探測設備不能準確確定PE管位置信息，通常采用對通電示蹤線進行探測來準確定位管道位置，從而獲取管道的基本信息。下面來講講一種地埋示蹤線用以提高檢測管道破損時的準確性的相關內容吧。

With the extensive application of PE pipes, the positioning and daily maintenance of pipes are becoming increasingly important. Now the detection equipment can not accurately determine the position information of PE pipes. It is usually used to detect the energized tracer line to accurately locate the position of pipes, so as to obtain the basic information of pipes. Let's talk about a buried tracer line to improve the accuracy of detecting pipeline damage.

地埋示蹤線包括：貼附在管道外側壁上的主線路；還包括報警器，所述主線路的兩端發分別與所述報警器的正及負連接；還包括與所述主線路連接的多個分支線路，多個所述分支線路沿所述主線路長度方向上間隔排列。

The buried trace line includes: the main line attached to the outer wall of the pipeline; It also includes an alarm, and both ends of the main line are respectively connected with the positive and negative connections of the alarm; It also includes a plurality of branch lines connected with the main line, and the plurality of branch lines are spaced along the length direction of the main line.

其中，每個分支線路包括通過所述主線路與所述報警器的正及負電連接的兩條分支線；且每條所述分支線穿過埋設所述管道的土層后外露；且每條所述分支線外露在所述土層后的一端可導電連通；還包括覆蓋每個分支線裸露的一端的端蓋。

Wherein, each branch line includes two branch lines electrically connected with the positive and negative of the alarm through the main line; And each branch line is exposed after passing through the soil layer where the pipe is buried; And one end of each branch line exposed behind the soil layer can be electrically connected; It also includes an end cover covering the exposed end of each branch line.

在上述技術方案中，當主線路出現損壞時，通過導通不同的分支線路來判斷主線路損壞的位置，可以短時間確定破損位置是否在這區間，并可檢查示蹤線附近管道是否也受到外力作用發生破損，從而進行復。減少搜索時間成本和大量開挖土地的造成的經濟成本和環境成本。

In the above technical scheme, when the main line is damaged, the damage position of the main line can be judged by connecting different branch lines. Whether the damage position is in this section can be determined in a short time, and whether the pipeline near the tracer line is also damaged by external force can be checked, so as to carry out restoration. Reduce the cost of search time and the economic and environmental costs caused by massive excavation of land.

在一個具體的實施方案中，每個分支線路的兩個分支線外露在所述土層的一端通過開關連接。方便導通分支線路。還包括多個保護管，且每個分支線路對應穿設在一個保護管內。提高分支線路的性，保證檢測時的準確性。

In a specific embodiment, two branch lines of each branch line are exposed at one end of the soil layer and connected by a switch. It is convenient to conduct branch lines. It also includes a plurality of protective tubes, and each branch line is correspondingly threaded in a protective tube. Improve the safety of branch lines and ensure the accuracy of detection.

所述保護管外露的一端設置有可以拆卸的密封端蓋。提高分支線的所處的環境，進而提高分支線的壽命。所述保護管外露的一端設置有密封端蓋，且所述開關為按壓開關，所述密封端蓋上設置有與所述按壓開關的按壓凸起配合的通孔，且所述通孔上覆蓋有彈性密封膜層。方便導通分支線路。

The exposed end of the protective tube is provided with a detachable sealing end cover. Improve the environment of the branch line, and then improve the service life of the branch line. The exposed end of the protective tube is provided with a sealing end cover, and the switch is a press switch. The sealing end cover is provided with a through hole matched with the press projection of the press switch, and the through hole is covered with an elastic sealing film layer. It is convenient to conduct branch lines.

每個分支線外露在土層的一端可拆卸的設置有密封該分支線內銅線的端蓋。提高分支線路的性，保證檢測時的準確性。每個所述分支線路上設置有標號。方便進行監控。所述標號設置在所述端蓋上。方便觀測標號。每個分支線為一個豎直的導線。保證檢測位置的準確性。

One end of each branch line exposed in the soil layer is detachably provided with an end cover for sealing the copper wire in the branch line. Improve the safety of branch lines and ensure the accuracy of detection. Each branch line is provided with a label. Convenient for monitoring. The label is arranged on the end cover. Convenient observation label. Each branch line is a vertical wire. Ensure the accuracy of the detection position.
