示蹤線與普通電線的區別在于，示蹤線的顏色一般比較搶眼，而普通電線是鉛鋁色。管道示蹤器是一款專為查找和定位地下非管道線路而設計的產品。有效了管道探管器無法探測非管道管道的問題，可廣泛用于管道、給水管道、排水管道等地下非管道管道的搜索定位。

The difference between tracer wire and ordinary wire is that the color of tracer wire is generally eye-catching, while ordinary wire is lead aluminum color. Pipeline tracer is a product specially designed for finding and locating underground non pipeline lines. It effectively solves the problem that the pipeline detector cannot detect non pipeline pipelines, and can be widely used for the search and positioning of underground non pipeline pipelines such as pipelines, water supply pipelines, drainage pipelines, etc.

示蹤線探測管線鋪設完畢后，應使用管線探測器對鋪設的可探測示蹤線進行探測性測試，確保管線導線連接正確，并記錄測試結果。將示蹤線的管線連接到管道定位器的變送器輸入端，變送器的接地端應盡量遠離變送器。使用接地樁或接地極進行接地，以降低接地電阻。使用接收器檢測接收到的發射信號。可以求出管道位移和埋深。

After the laying of the tracer line detection pipeline, the pipeline detector shall be used to carry out the detectability test on the laid detectable tracer line to ensure the correct connection of the pipeline conductor, and the test results shall be recorded. Connect the pipeline of the tracer line to the transmitter input end of the pipe locator, and the grounding end of the transmitter should be as far away from the transmitter as possible. Use the grounding pile or grounding electrode for grounding to reduce the grounding resistance. Use the receiver to detect the received transmission signal. The displacement and buried depth of the pipeline can be calculated.

此外，埋地塑料管在沒有管道或管道內沒有液體的情況下，還具有不導電、無磁性和基本絕緣的特點。管道檢測等方法難以識別，檢測是世界性難題。

In addition, the buried plastic pipe has the characteristics of non-conductive, non-magnetic and basic insulation when there is no pipe or liquid in the pipe. Pipeline detection and other methods are difficult to identify, and detection is a worldwide problem.

在實際應用中，如果管道需要更換、維修或管道改造施工，如果管道無法檢測定位（例如：沒有管道示蹤系統的埋地PE燃氣管、埋地PE給排水管等），也可用以下方法定位埋地塑料管：應查明相應工程的施工圖，大致確定埋管的位置、方向和深度。然后使用超聲確定管道的位置。如果施工圖丟失或施工圖標準不明確，可直接采用聲波定位法確定管道位置。

In practical application, if the pipeline needs to be replaced, repaired or reconstructed, and if the pipeline cannot be detected and positioned (for example, buried PE gas pipe without pipeline tracking system, buried PE water supply and drainage pipe, etc.), the following methods can also be used to locate the buried plastic pipe: the construction drawings of the corresponding project should be checked to roughly determine the location, direction and depth of the buried pipe. Then use ultrasound to determine the position of the pipe. If the construction drawing is missing or the construction drawing standard is not clear, the acoustic positioning method can be directly used to determine the pipeline position.

該方法使用聲波定位設備，基于聲波探測原理，由發射和接收兩部分組成。音頻驅動器通過轉接器與管道系統檢測井中裸露的管件和管道連接，對其施加特定組合頻率的聲波信號。然后通過手持接收裝置沿路面接收相應的聲波信號，結合耳機反饋的聲波信號強度和數顯聲波大小的綜合判斷，可以快速定位埋地塑料管；效率和準確性都不錯。

This method uses acoustic positioning equipment, based on the principle of acoustic detection, and consists of transmitting and receiving parts. The audio driver is connected with the exposed pipe fittings and pipes in the pipeline system detection well through the adapter, and applies the acoustic signal of specific combined frequency to them. Then, the hand-held receiving device receives the corresponding acoustic signal along the road, and combined with the comprehensive judgment of the acoustic signal strength fed back by the headset and the size of the digital display acoustic wave, the buried plastic pipe can be quickly located; Efficiency and accuracy are both good.

對于無管道、管道內無液體的埋地塑料管道，簡單方便的示蹤方法仍然是在鋪設時安裝管道示蹤線。聲波定位方式增加了人工和設備成本，不利于維修和更換。因此，管道示蹤系統的埋地PE燃氣管、埋地PE給排水管還是比較常用的方法。

For buried plastic pipelines without pipelines and liquid in the pipelines, the simple and convenient tracing method is still to install pipeline tracing lines when laying. Acoustic positioning increases the cost of labor and equipment, which is not conducive to maintenance and replacement. Therefore, buried PE gas pipe and buried PE water supply and drainage pipe of pipeline tracing system are still common methods.
