你知道常见的示踪线几种类型具体包含什么内容吗？下面燃气示踪线厂家为您进行解答，希望能够给您有效的帮助。

Do you know the specific contents of several types of common trace lines? The following manufacturer of the gas trace line will answer the question for you, and I hope it can help you effectively.

地面标志

Ground signs

在地面相应位置上进行标记,埋设标志、标志砖、标志贴等。这种方式直观易找,但受地面环境限制,如在快速路上很难设置。遇道路维修或拆迁等情况,还会大量丢失标志。现阶段地面标记物均采用以上标志。

Mark on the corresponding position on the ground, and bury signs, sign bricks, sign stickers, etc. This method is intuitive and easy to find, but is limited by the ground environment, for example, it is difficult to set on the expressway. In case of road maintenance or demolition, a large number of signs will be lost. At present, the above signs are used for ground markers.

金属薄膜示踪带

Metal film tracer tape

在PE管道上方敷设金属薄膜示踪带,然后用探管仪进行探测。示踪带中的金属薄膜具有导电性,理论上可以体现出金属管的特性,但实际上由于金属薄膜的截面积太小,导电性不好,受周围金属管道干扰大,致使探测效果非常差,只有在干扰小且距离地面很近的地方才能被探测到。而且辐射过程中，每100米需进行一次连接，如连接不当，在后期使用过程中因土壤沉降会导致示踪带断裂，进而无法检测。

The metal film tracing tape is laid above the PE pipe, and then the pipe detector is used for detection. The metal film in the tracer belt has conductivity, which can theoretically reflect the characteristics of the metal tube. But in fact, because the cross-sectional area of the metal film is too small, the conductivity is poor, and the interference from the surrounding metal pipes is large, the detection effect is very poor, and can only be detected in a place with small interference and close to the ground. In addition, during the radiation process, a connection is required every 100 meters. If the connection is improper, the tracer zone will be broken due to the soil settlement in the later use process, and thus cannot be detected.

金属示踪线

Metal tracer

为提高示踪物体的导电性,我们曾使用金属示踪线来替代金属薄膜示踪带。由于示踪线的线芯是铜,且具有一定的截面积,因此导电性明显好于薄膜示踪带,尤其在刚埋下去的时候,探测效果较好。但随着时间延长,示踪线暴露出很大问题。a.示踪线一旦有断点,如施工时被挖断自然锈蚀、连接时没接牢等,从断点往后就无法被探测到。b.相对于其他地下管道或线路,示踪线的导电性没有它们好,因此造成探测信号过于微弱,以于混淆管道位置。而且抗拉性能差，在定向钻穿越中无法敷设。

In order to improve the conductivity of the tracer, we have used metal tracer wire to replace the metal film tracer tape. Since the core of the trace wire is copper and has a certain cross-sectional area, its conductivity is obviously better than that of the film trace tape, especially when it is just buried, the detection effect is better. However, with the extension of time, the tracer line exposed a lot of problems. a. Once there is a breakpoint in the trace line, such as natural corrosion due to excavation during construction, and failure to connect firmly, it cannot be detected from the breakpoint onwards. b. Compared with other underground pipelines or lines, the conductivity of the trace line is not as good as them, so that the detection signal is too weak to confuse the pipeline position. Moreover, the tensile property is poor, and it cannot be laid in directional drilling crossing.
