示踪线铺设时的5点相识事项

您知道示踪线铺设注重事项是什么吗?下面各人随着地埋示踪线厂家一起来相识学习一下吧!
Do you know what the precautions for trace line laying are? Now let's follow the buried trace wire manufacturer to learn about it!
1、咱们在踪线埋设时应紧贴PE管道呈直线状,并且位于管道的顶面为好。
1. When burying the trace line, we should closely stick to the PE pipe in a straight line and be on the top of the pipe.
2、在窨井或出地处示踪线应该预留出一定长度的导线(1m以上为宜),供勘探施加信号所用。这样可提髙勘探功率和精度。
2. A certain length of wire (more than 1m is appropriate) shall be reserved for the trace line in the inspection well or out of the ground for the application of signals for exploration. This can improve the exploration power and accuracy.
3、示踪线的讨论或是分支点一定要衔接牢靠,并且坚持优异导电,并用绝缘胶布包好,避免地下湿润而造成侵蚀断线状态,使勘探信号中止。管道的钢塑转化讨论处示踪线可以焊接在法兰上,接点处做好防腐处置惩罚,避免日久后侵蚀断线。
3. The connector or branch point of the trace line must be firmly connected, and maintain excellent conductivity, and be wrapped with insulating tape to prevent corrosion and breakage caused by underground moisture, which will stop the exploration signal. The trace line at the steel plastic conversion joint of the pipeline can be welded on the flange, and the joint shall be subject to anti-corrosion treatment to prevent corrosion and wire breakage after a long time.

4、为增添示踪线的信号强度并让信号散布匀称,施工时须只管减小示踪线埋地最后的接地电阻,接纳剥掉绝缘层袒露芯线30cm的优异接境地伐。特殊是关于长度较短的分支管的最后,一定要接地优异,不然分支上的信号会十分弱而勘探不到。
4. In order to increase the signal strength of the trace wire and make the signal spread evenly, the grounding resistance at the end of the buried trace wire must be reduced as much as possible during construction, and the outstanding grounding method of stripping the insulation layer to expose the core wire for 30cm shall be adopted. Especially for the end of the branch pipe with short length, the grounding must be outstanding, otherwise the signal on the branch pipe will be very weak and cannot be detected.
5、在非开挖工程施工中,PE管道外面的示踪线在拖管历程中简朴被扯断,轻盈的步伐是选择截面积更大、强度更高的导线或钢丝绳,或许在管道的内部预穿一条示踪线即可避免断线,其勘探效果犹如在外面一样,但这样做时需处置惩罚好内部示踪线头与外面示踪线衔接的问题。
5. In the trenchless engineering construction, the tracer line outside the PE pipe is simply pulled off during the pipe dragging process. The simple way is to select a conductor or wire rope with larger sectional area and higher strength. Perhaps a tracer line can be pre threaded inside the pipe to prevent the line from breaking. The exploration effect is the same as that outside, but the connection between the internal tracer line head and the external tracer line needs to be handled properly when doing so.
别的咱们在某些特殊状态下,对PE管道无法应用示踪线,这时可接纳预埋示踪球的步伐知足以后的勘探定位需要等。更多相关内容就来我们网站举行咨询相识!
In addition, under some special circumstances, we can not apply the tracer line to PE pipes. At this time, we can use the method of embedding the tracer ball to meet the needs of future exploration and positioning. More relevant content will come to our website Ask about it!
