示踪线与普通电线的区别在于，示踪线的颜色一般比较抢眼，而普通电线是铅铝色。管道示踪器是一款专为查找和定位地下非管道线路而设计的产品。有效了管道探管器无法探测非管道管道的问题，可广泛用于管道、给水管道、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.

示踪线探测管线铺设完毕后，应使用管线探测器对铺设的可探测示踪线进行探测性测试，确保管线导线连接正确，并记录测试结果。将示踪线的管线连接到管道定位器的变送器输入端，变送器的接地端应尽量远离变送器。使用接地桩或接地极进行接地，以降低接地电阻。使用接收器检测接收到的发射信号。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，埋地塑料管在没有管道或管道内没有液体的情况下，还具有不导电、无磁性和基本绝缘的特点。管道检测等方法难以识别，检测是世界性难题。

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.

在实际应用中，如果管道需要更换、维修或管道改造施工，如果管道无法检测定位（例如：没有管道示踪系统的埋地PE燃气管、埋地PE给排水管等），也可用以下方法定位埋地塑料管：应查明相应工程的施工图，大致确定埋管的位置、方向和深度。然后使用超声确定管道的位置。如果施工图丢失或施工图标准不明确，可直接采用声波定位法确定管道位置。

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.

该方法使用声波定位设备，基于声波探测原理，由发射和接收两部分组成。音频驱动器通过转接器与管道系统检测井中裸露的管件和管道连接，对其施加特定组合频率的声波信号。然后通过手持接收装置沿路面接收相应的声波信号，结合耳机反馈的声波信号强度和数显声波大小的综合判断，可以快速定位埋地塑料管；效率和准确性都不错。

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.

对于无管道、管道内无液体的埋地塑料管道，简单方便的示踪方法仍然是在铺设时安装管道示踪线。声波定位方式增加了人工和设备成本，不利于维修和更换。因此，管道示踪系统的埋地PE燃气管、埋地PE给排水管还是比较常用的方法。

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.
