地埋示蹤線(xiàn)鋪設(shè)注意要點(diǎn)

Key points to pay attention to when laying underground tracer lines

　　1.使用時(shí)注意示蹤線(xiàn)的放線(xiàn)長(zhǎng)度，用多少放多少，不能將示蹤線(xiàn)一次性全部倒出來(lái)。

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.地埋示蹤線(xiàn)隨管一起進(jìn)入定向鉆孔時(shí),要有人看管，避免示蹤線(xiàn)打結(jié)、或纏繞在一起。

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.比較好有一個(gè)簡(jiǎn)單的放線(xiàn)架，把示蹤線(xiàn)固定在放線(xiàn)架上，讓示蹤線(xiàn)和管材同時(shí)拖動(dòng)。

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.在拖管的過(guò)程中，示蹤線(xiàn)不能被小樹(shù)叢或其它障礙物絆掛，避免示蹤線(xiàn)被拉斷。

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.示蹤線(xiàn)和管材頂部要捆扎牢固，避免管材在穿越時(shí)示蹤線(xiàn)脫落。如果示蹤線(xiàn)要出地表面，需適當(dāng)多預(yù)留一定的長(zhǎng)度。建議出地后的示蹤線(xiàn)預(yù)留長(zhǎng)度為1.5米左右，以備探測(cè)使用。

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.示蹤線(xiàn)在定向鉆使用過(guò)程中，不能有接頭。

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

　　7.在非開(kāi)挖工程施工中，PE管道外面的地埋示蹤線(xiàn)在拖管過(guò)程中容易被扯斷，簡(jiǎn)便的辦法是選擇截面積更大、強(qiáng)度更高的導(dǎo)線(xiàn)或鋼絲繩，或者在管道的內(nèi)部預(yù)穿一條示蹤線(xiàn)即可避免斷線(xiàn)，其探測(cè)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(xiàn)頭與外面示蹤線(xiàn)連接的問(wèn)題。

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.
