Connect the metal wire of the tracer wire with the transmitter input end of the pipe locator, and the transmitter grounding end should be as far away from the transmitter as possible. Use the grounding pile or pole grounding to reduce the grounding resistance. Use the receiver to detect and receive the transmitted signal. The displacement and buried depth of the pipeline can be found.

一般宜選擇截面積大于2.5毫米的多股銅質(zhì)電線，鋪設(shè)時(shí)盡量讓示蹤線保持在管道的頂部位置，在三通等分支處應(yīng)將導(dǎo)線接頭的絕緣層剝掉，把銅芯絞在一起數(shù)圈，然后用絕緣膠布裹好接頭，以保持良好的導(dǎo)電性；

Generally, multi strand copper wires with a sectional area of more than 2.5 mm should be selected. When laying, the trace wire should be kept at the top of the pipe as much as possible. At the tee branch, the insulation layer of the wire joint should be stripped off, the copper core twisted together for several turns, and then the joint should be wrapped with insulating tape to maintain good conductivity;

示蹤線應(yīng)留有一定的線頭余量，并避免導(dǎo)線頭被泥土或雜物覆蓋，為減少無(wú)法出地的示蹤線末端的接地電阻，需采取剝掉絕緣層裸露芯線30cm的良好接地措施，對(duì)于采取定向鉆方式鋪設(shè)的PE管道，應(yīng)選用強(qiáng)度更大的導(dǎo)線，以避免在施工中被拉斷,導(dǎo)致無(wú)法探測(cè)定位；

A certain amount of wire head allowance shall be reserved for the trace wire, and the wire head shall not be covered by soil or sundries. In order to reduce the grounding resistance of the end of the trace wire that cannot go out of the ground, it is necessary to take good grounding measures to strip the insulation layer to expose the core wire for 30cm. For the PE pipe laid by directional drilling, the wire with greater strength shall be selected to avoid being pulled off during construction, resulting in the inability to detect and locate;

當(dāng)導(dǎo)線直徑遠(yuǎn)小于埋深并忽略地介質(zhì)和空氣的介質(zhì)變化時(shí)，示蹤線可視為均勻介質(zhì)中的一條無(wú)限。更多相關(guān)事項(xiàng)可以隨時(shí)來(lái)我們網(wǎng)站http://tianyals.cn咨詢了解！

When the diameter of the conductor is far less than the buried depth and the medium change of the ground medium and air is ignored, the trace line can be regarded as an infinite line in the uniform medium. More related matters can come to our website at any time http://tianyals.cn Ask about it!
