随着社会的发展和人民生活水平的提高，燃气和供水的使用已经在大多数家庭中普及，特别是在地下燃气、自来水、排水、排污管道较为复杂的城市。以前的管道都是用金属材料制作的，所以很容易使用电子检测设备来检测金属管道的当前位置，给维护或施工带来了方便，也避免了一些不必要的隐患。

With the development of society and the improvement of people's living standards, the use of gas and water supply has been popularized in most families, especially in cities with complex underground gas, tap water, drainage and sewage pipelines. In the past, pipelines were made of metal materials, so it is easy to use electronic detection equipment to detect the current position of metal pipelines, which brings convenience to maintenance or construction and avoids some unnecessary safety hazards.

但由于金属管道长期埋在地下，容易腐蚀造成管道损坏，导致漏气或漏水。这不仅造成资源浪费，而且带来严重的隐患。因此，考虑用塑料管代替部分管道工程建设。由于塑料管道具有工程造价低、不易腐蚀、对输送物质污染少等优点，近年来塑料管道在城市管网建设中得到了广泛应用，特别是在输气、供水等方面应用较多。管道。

However, due to the long-term buried underground of metal pipelines, it is easy to cause pipeline damage due to corrosion, resulting in air leakage or water leakage. This not only wastes resources, but also brings serious security risks. Therefore, plastic pipes are considered to replace some pipeline engineering construction. Due to the advantages of low engineering cost, not easy to corrode and less pollution to the transported substances, plastic pipelines have been widely used in the construction of urban pipe networks in recent years, especially in gas transmission, water supply and other aspects. The Conduit.

但由于塑料管材是绝缘体，无法用电子检测设备准确测量管材的位置，因此在施工过程中很容易被工程机械割破、漏水，带来不必要的隐患。特别是一些埋地塑料管道使用示踪胶带保护管道，费时费力，不经济，而且当带有示踪痕迹的土层被破坏时，很难确定管道的准确位置，不方便日后维护。或其他建筑。

However, as the plastic pipe is an insulator, it is impossible to accurately measure the position of the pipe with electronic detection equipment. Therefore, it is easy to be cut and leaked by construction machinery during the construction process, resulting in unnecessary safety hazards. In particular, some buried plastic pipelines use tracer tape to protect the pipeline, which is time-consuming, laborious and uneconomical. Moreover, when the soil layer with trace is damaged, it is difficult to determine the exact locations of the pipeline, which is not convenient for future maintenance. Or other buildings.

传统的示踪线由铜芯线和绝缘层组成。铜芯线的强度是有限的。在施工过程中，施工人员经常在拉线过程中用力过大，会导致示踪线断裂，或者在使用过程中。在外力作用下，铜芯线常因强度不足而被切断，导致检测时无法通电，失去示踪功能。为了克服上述缺点，新型地埋示踪线可以辅助电子测试设备测量管道的准确位置，为以后的维护或其他施工带来方便。

The traditional tracer wire is composed of copper core wire and insulating layer. The strength of copper core wire is limited. In the construction process, the construction personnel often exert too much force in the pulling process, which will lead to the fracture of the tracer line, or in the use process. Under the action of external force, the copper core wire is often cut off due to insufficient strength, resulting in the failure of power on during detection and the loss of tracking function. In order to overcome the above shortcomings, the new buried tracer can assist the electronic testing equipment to measure the accurate position of the pipeline, which brings convenience for future maintenance or other construction.

工作原理：本实用新型与燃气、给水、排水、污水塑料管一起铺设。检测时，给示踪线加上一定强度的电流信号，通过探测示踪线电流产生的电磁场的中心位置，确定示踪线的空间位置，从而确定埋藏位置塑料管，以方便日后维修或其他施工，防止燃气、给水、排水、排污管道被施工机械割断、泄漏，避免由此引起的燃气泄漏和爆炸事故的发生。

Working principle: the utility model is laid together with gas, water supply, drainage and sewage plastic pipes. During the detection, add a certain strength of current signal to the tracer line, and determine the spatial position of the tracer line by detecting the central position of the electromagnetic field generated by the current of the tracer line, so as to determine the buried position of the plastic pipe, so as to facilitate future maintenance or other construction, prevent the gas, water supply, drainage and sewage pipelines from being cut and leaked by the construction machinery, and avoid the gas leakage and explosion accidents caused thereby.
