地埋示踪线系统，其原理主要是依赖并行管敷设的金属线，使用电流穿过金属线爆发的磁场转变，定位金属示踪线的位置，进而推测PE管的位置。
The principle of the buried trace line system is mainly to locate the position of the metal trace line and speculate the position of the PE pipe by relying on the metal line laid in parallel pipes and the magnetic field change generated by the current passing through the metal line.
这种系统的优点是产品较为成熟，海内使用履历多，施工要领简朴，工人易于操作，与原有的铜制钢管系统示踪要领的检测差别不大，与现有系统易整合。
The advantages of this system are that the product is relatively mature, the domestic use experience is much, the construction method is simple, the workers are easy to operate, the detection gap with the original copper steel pipe system tracing method is small, and it is easy to integrate with the existing system.
示踪线的形式与性能：
Form and performance of trace line:
1、钢丝塑料薄膜示踪线，是一种由钢线或其他金属丝与PE塑料薄膜压制而成，经常与警示带整合使用，钢丝直径在0.5mm?左右。
1. Steel wire plastic film tracing line is a kind of steel wire or other metal wire pressed with PE plastic film, which is often used in combination with warning tape. The diameter of steel wire is 0.5mm? about.
性能：由钢丝为导体，由于横截面积小造成不易毗连，电阻大，探测距离有限只有十几米到几十米，现实验工中易断裂，电气有用连通性易被破损，难以知足现实需要。
Performance: The steel wire is the conductor, which is difficult to connect due to its small cross-sectional area. The resistance is large, and the detection distance is limited to only tens to tens of meters. It is easy to break in actual construction, and the effective electrical connectivity is easy to be damaged, which is difficult to meet the actual needs.
2、电线示踪线，使用铜制或铝制电线缆为示踪线，截面积多接纳2.5-4mm?。
2. The copper or aluminum wire and cable are used as the trace wire of the electric wire, and the sectional area is usually 2.5-4mm?.
性能：由于接纳电线或电缆，其检测距离远、效果好，但造价相对腾贵。电线的外外貌绝缘层是PVC，这种质料麦迪后易老化，相对PE材质有所缺乏，电线金属芯多是铜或铝材质，抗拉有局限性，在用于通例铺设及非开挖铺设时，断裂几率较高。
Performance: Due to the use of wires or cables, the detection distance is far and the effect is good, but the cost is relatively expensive. The insulation layer on the outer surface of the wire is PVC, which is easy to age after being made of McGrady. Compared with the PE material, it is insufficient. The metal core of the wire is mostly made of copper or aluminum, and its tensile strength is limited. When it is used for conventional laying and trenchless laying, the fracture probability is high.
3、专用金属示踪线，是由专用金属线芯（铜包钢）和PE外�；げ阕槌�，截面积多接纳205-7mm?。
3. The special metal tracer wire is composed of special metal core (copper clad steel) and PE outer protective layer, with a sectional area of 205-7mm?.
性能：金属示踪线，接纳PE作为外�；げ�，绝缘、防腐、防水、抗老化，芯层中的铜层适当增强导电性，提高电信号，通讯科有用增添增强线体强度，导电性稍差但强度和力学性能好。在西欧金属示踪线应用了多年，具有较好的经济效应。
Performance: The metal tracer wire uses PE as the external protective layer, which is insulated, anti-corrosion, waterproof and anti-aging. The copper layer in the core layer properly enhances the conductivity and improves the electrical signal. The communication department effectively increases the strength of the wire body. The conductivity is slightly poor, but the strength and mechanical properties are good. It has been used in Europe and America for many years and has good economic effect.
