地(di)埋(mai)示蹤(zong)線(xian)鋪設註(zhu)意要點(dian)

Key points to pay attention to when laying underground tracer lines

　　1.使(shi)用(yong)時(shi)註(zhu)意示蹤(zong)線(xian)的(de)放(fang)線(xian)長(chang)度(du)，用多(duo)少放(fang)多(duo)少，不能(neng)將(jiang)示蹤(zong)線(xian)壹次(ci)性(xing)全部(bu)倒出(chu)來(lai)。

1. When using, pay attention to the length of the tracer line, use as much as you want, and do not pour out all the tracer lines at once.

　　2.地(di)埋(mai)示蹤(zong)線(xian)隨管(guan)壹起(qi)進入定向(xiang)鉆孔時(shi),要(yao)有人看管，避免示蹤(zong)線(xian)打(da)結、或(huo)纏(chan)繞(rao)在壹起(qi)。

When the buried tracer line enters the directional drilling hole together with the pipe, someone should be watching to prevent the tracer line from getting tangled or tangled together.

　　3.比較好有壹個(ge)簡(jian)單(dan)的(de)放(fang)線(xian)架(jia)，把(ba)示蹤(zong)線(xian)固定在放(fang)線(xian)架(jia)上(shang)，讓(rang)示蹤(zong)線(xian)和(he)管材(cai)同(tong)時(shi)拖(tuo)動(dong)。

3. It is better to have a simple cable rack, fix the tracer line on the rack, and drag both the tracer line and the pipe at the same time.

　　4.在拖(tuo)管的(de)過(guo)程中，示蹤(zong)線(xian)不能(neng)被(bei)小樹(shu)叢(cong)或(huo)其它障(zhang)礙物絆掛(gua)，避(bi)免示蹤(zong)線(xian)被(bei)拉(la)斷(duan)。

During the process of dragging the pipe, the tracking line should not be tripped by small trees or other obstacles to avoid being pulled apart.

　　5.示蹤(zong)線(xian)和(he)管材(cai)頂(ding)部(bu)要捆紮(zha)牢(lao)固，避免管(guan)材(cai)在穿越(yue)時(shi)示蹤(zong)線(xian)脫(tuo)落(luo)。如果示蹤(zong)線(xian)要出地(di)表面(mian)，需適當多(duo)預(yu)留(liu)壹定(ding)的(de)長(chang)度(du)。建議出地(di)後(hou)的(de)示蹤(zong)線(xian)預(yu)留(liu)長(chang)度(du)為(wei)1.5米(mi)左(zuo)右(you)，以(yi)備(bei)探測(ce)使(shi)用(yong)。

5. The tracer line and the top of the pipe should be securely tied to prevent the tracer line from falling off when the pipe passes through. If the tracer line needs to leave the ground surface, a certain length should be reserved appropriately. It is recommended to reserve a length of about 1.5 meters for the tracer line after leaving the site for detection purposes.

　　6.示蹤(zong)線(xian)在定向(xiang)鉆使(shi)用(yong)過(guo)程中，不能(neng)有接頭(tou)。

During the use of directional drilling, the tracer line should not have any joints.

　　7.在非開挖(wa)工(gong)程施工(gong)中，PE管道外面(mian)的(de)地(di)埋(mai)示蹤(zong)線(xian)在拖(tuo)管過(guo)程中容(rong)易被(bei)扯斷(duan)，簡(jian)便(bian)的(de)辦(ban)法(fa)是(shi)選擇截(jie)面(mian)積更大(da)、強(qiang)度更高(gao)的(de)導(dao)線(xian)或(huo)鋼(gang)絲(si)繩(sheng)，或(huo)者(zhe)在管道的(de)內部(bu)預(yu)穿(chuan)壹條(tiao)示蹤(zong)線(xian)即可避(bi)免斷(duan)線(xian)，其探(tan)測(ce)效果如同在外面(mian)壹樣(yang)，但(dan)這樣(yang)做(zuo)時(shi)需處理好內部(bu)示蹤(zong)線(xian)頭與(yu)外面(mian)示蹤(zong)線(xian)連接的(de)問(wen)題(ti)。

7. In non excavation engineering construction, the buried tracer line outside the PE pipeline is prone to breakage during the dragging process. A simple method is to choose a larger cross-sectional area and higher strength wire or steel wire rope, or pre thread a tracer line inside the pipeline to avoid breakage. The detection effect is the same as outside, but when doing so, it is necessary to handle the problem of connecting the internal tracer line head to the external tracer line.
