燃?xì)獾芈馪E管隨管敷設(shè)的示蹤線,目的是為了以后能更方便的找到燃?xì)夤艿溃ㄊ且院笳曳奖阏夜艿赖囊环N輔助手段)。下面來看看相關(guān)內(nèi)容吧。
The tracer line laid along with the gas buried PE pipe is designed to make it easier to find the gas pipe in the future (an auxiliary means to find the pipe in the future). Let's take a look at the relevant content.
1、示蹤線安裝后隨管道埋地后,在驗(yàn)收時(shí)應(yīng)用地下管道探測儀(該儀器有點(diǎn)貴,但應(yīng)是燃?xì)庑袠I(yè)的應(yīng)配設(shè)施,特別是生產(chǎn)運(yùn)營部門)來檢驗(yàn)示蹤線的完整性,原理及實(shí)用方法十分簡單。
1. After the tracer line is buried with the pipeline after installation, the underground pipeline detector (which is a little expensive, but it should be an appropriate facility in the gas industry, especially the production and operation Department) is used to check the integrity of the tracer line during acceptance. The principle and practical method are very simple.
2、在非開挖工程中(定向鉆作業(yè)),為了保證示蹤線的完整性,示蹤線的規(guī)格通常采用4.0平方的單芯銅錢,且要用雙線,綁在將要拖入的燃?xì)釶E管上,在拖管時(shí)隨管一同拖入。
2. In trenchless Engineering (directional drilling operation), in order to ensure the integrity of the tracer line, the specification of the tracer line is usually 4.0 square meters of single core copper coin, which should be tied to the gas PE pipe to be dragged in with two lines, and dragged in with the pipe when dragging.
3、因在查找管線用到示蹤線時(shí)是依靠閉合電路中的電流來進(jìn)行操作的,由于電阻問題,電流強(qiáng)度用隨著檢測點(diǎn)與信號發(fā)射機(jī)的距離增加而減弱,一般來說,2.5平方的單芯銅線作示蹤線,其發(fā)射機(jī)的信號有效范圍半徑為300米(示蹤線越好有效半徑越大)。
3. Because the tracer wire used in the pipeline search depends on the current in the closed circuit. Due to the resistance problem, the current intensity decreases with the increase of the distance between the detection point and the signal transmitter. Generally speaking, 2.5 square single core copper wire is used as the tracer wire, and the signal effective range radius of the transmitter is 300 meters (the better the tracer wire is, the greater the effective radius is).
示蹤線連續(xù)敷設(shè)檢測位置可直接設(shè)置在閥門井、凝水井內(nèi),如300米內(nèi)沒有閥門井或其他可以檢測示蹤線的位置,應(yīng)單獨(dú)設(shè)立示蹤線檢測井;檢測井應(yīng)在竣工圖上標(biāo)出,以方便以后使用。
The detection position of the continuous laying of the tracer line can be directly set in the valve well and condensate well. If there is no valve well within 300 meters or other positions where the tracer line can be detected, the tracer line detection well should be set up separately; The inspection well shall be marked on the as built drawing for future use.
4、
管道示蹤線安裝不是技術(shù)含量太高的工作,要綁在燃?xì)夤艿郎希ㄔ瓌t上是綁在正上方,因?yàn)樗€肩負(fù)著測管道埋深的任務(wù)),在接頭處要處理好,如使用專用接線套管;用錫焊等,以防受地下潮濕,土壤酸性等壞境的影響,而在接點(diǎn)處失去導(dǎo)電性。
4. The installation of pipeline tracing line is not a work with too high technical content. It should be tied to the gas pipeline (in principle, it should be tied directly above, because it also undertakes the task of measuring the buried depth of the pipeline). It should be handled well at the joint, such as using a special wiring sleeve; Tin welding is used to prevent the loss of conductivity at the contact due to the influence of underground humidity, soil acidity and other bad environments.
