您知道示蹤線鋪設(shè)注意事項(xiàng)是什么嗎？下面大家跟著地埋示蹤線廠家一起來(lái)了解學(xué)習(xí)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、咱們?cè)谯櫨€埋設(shè)時(shí)應(yīng)緊貼PE管道呈直線狀，并且位于管道的頂面為好。

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、在窨井或出地處示蹤線應(yīng)該預(yù)留出一定長(zhǎng)度的導(dǎo)線（1m以上為宜），供勘探施加信號(hào)所用。這樣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、示蹤線的接頭或是分支點(diǎn)一定要銜接牢固，并且保持杰出導(dǎo)電,并用絕緣膠布包好，防止地下潮濕而造成腐蝕斷線狀況，使勘探信號(hào)中止。管道的鋼塑轉(zhuǎn)化接頭處示蹤線可以焊接在法蘭上，接點(diǎn)處做好防腐處理，防止日久后腐蝕斷線。

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、為增加示蹤線的信號(hào)強(qiáng)度并讓信號(hào)散布均勻，施工時(shí)須盡量減小示蹤線埋地結(jié)尾的接地電阻，采納剝掉絕緣層暴露芯線30cm的杰出接地辦法。特別是關(guān)于長(zhǎng)度較短的分支管的結(jié)尾，一定要接地杰出，不然分支上的信號(hào)會(huì)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、在非開(kāi)挖工程施工中，PE管道外面的示蹤線在拖管過(guò)程中簡(jiǎn)單被扯斷，簡(jiǎn)便的辦法是選擇截面積更大、強(qiáng)度更高的導(dǎo)線或鋼絲繩，或許在管道的內(nèi)部預(yù)穿一條示蹤線即可防止斷線，其勘探效果如同在外面一樣，但這樣做時(shí)需處理好內(nèi)部示蹤線頭與外面示蹤線銜接的問(wèn)題。

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.

此外咱們?cè)谀承┨厥鉅顩r下，對(duì)PE管道無(wú)法應(yīng)用示蹤線，這時(shí)可采用預(yù)埋示蹤球的辦法滿意今后的勘探定位需要等。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://tianyals.cn進(jìn)行咨詢了解！

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 http://tianyals.cn Ask about it!
