随着PE管道大量应用，管道的定位和日常维护日益重要，现在探测设备不能准确确定PE管位置信息，通常采用对通电示踪线进行探测来准确定位管道位置，从而获取管道的基本信息。下面来讲讲一种地埋示踪线用以提高检测管道破损时的准确性的相关内容吧。

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.

地埋示踪线包括：贴附在管道外侧壁上的主线路；还包括报警器，所述主线路的两端发分别与所述报警器的正及负连接；还包括与所述主线路连接的多个分支线路，多个所述分支线路沿所述主线路长度方向上间隔排列。

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，每个分支线路包括通过所述主线路与所述报警器的正及负电连接的两条分支线；且每条所述分支线穿过埋设所述管道的土层后外露；且每条所述分支线外露在所述土层后的一端可导电连通；还包括覆盖每个分支线裸露的一端的端盖。

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.

在上述技术方案中，当主线路出现损坏时，通过导通不同的分支线路来判断主线路损坏的位置，可以短时间确定破损位置是否在这区间，并可检查示踪线附近管道是否也受到外力作用发生破损，从而进行复。减少搜索时间成本和大量开挖土地的造成的经济成本和环境成本。

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.

在一个具体的实施方案中，每个分支线路的两个分支线外露在所述土层的一端通过开关连接。方便导通分支线路。还包括多个保护管，且每个分支线路对应穿设在一个保护管内。提高分支线路的性，保证检测时的准确性。

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.

所述保护管外露的一端设置有可以拆卸的密封端盖。提高分支线的所处的环境，进而提高分支线的寿命。所述保护管外露的一端设置有密封端盖，且所述开关为按压开关，所述密封端盖上设置有与所述按压开关的按压凸起配合的通孔，且所述通孔上覆盖有弹性密封膜层。方便导通分支线路。

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.

每个分支线外露在土层的一端可拆卸的设置有密封该分支线内铜线的端盖。提高分支线路的性，保证检测时的准确性。每个所述分支线路上设置有标号。方便进行监控。所述标号设置在所述端盖上。方便观测标号。每个分支线为一个竖直的导线。保证检测位置的准确性。

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.
