Function of gas pipeline warning tape

當(dāng)開挖施工時(shí)，如挖到燃?xì)饩編?，則表示在下方0.30.5米處有燃?xì)夤艿?，起到了警示和保護(hù)作用。2、示蹤作用。尋找地埋燃?xì)夤艿罆r(shí)，找到警示帶即找到了管道，起到了示蹤作用。3、現(xiàn)在的警示帶有示蹤線，利用測(cè)試儀器在不開挖的情況下，準(zhǔn)確為管道定位。

When excavating and constructing, if a gas warning tape is excavated, it indicates that there is a gas pipeline 0.3 to 0.5 meters below, which serves as a warning and protection function. 2. Tracing effect. When searching for buried gas pipelines, the warning tape is found to locate the pipeline, which serves as a tracer. 3. The current warning comes with a tracer line, which uses testing instruments to accurately locate the pipeline without excavation.

燃?xì)夤艿谰編裨O(shè)要點(diǎn)

Key points for embedding warning tapes for gas pipelines

1.溝槽開挖。

1. Trench excavation.

(1)混凝土路面和瀝青路面的開挖應(yīng)使用切割機(jī)切割。

(1) The excavation of concrete and asphalt pavement should be done using a cutting machine.

(2)管道溝槽應(yīng)按設(shè)計(jì)規(guī)定的平面位置和標(biāo)高開挖。當(dāng)采用人工開挖且無(wú)地下水時(shí)，槽底預(yù)留值應(yīng)為0.05~0.10m;管道安裝前應(yīng)人工清底設(shè)計(jì)標(biāo)高。

(2) The pipeline trench should be excavated according to the plane position and elevation specified in the design. When manual excavation is used and there is no groundwater, the reserved value at the bottom of the trench should be 0.05-0.10m; Before pipeline installation, the bottom should be manually cleaned to the design elevation.

(3)管溝溝底寬度和工作尺寸，應(yīng)根據(jù)現(xiàn)場(chǎng)實(shí)際情況和管道敷設(shè)方法確定。

(3) The width and working size of the trench bottom should be determined based on the actual situation on site and the pipeline laying method.

(4)局部超挖部分應(yīng)回填夯實(shí)。當(dāng)溝底無(wú)地下水時(shí)，超挖在0.15m以內(nèi)，可采用原土回填;超挖在0.15m以上，可采用石灰土處理。當(dāng)溝底有地下水或水量較大時(shí)，應(yīng)采用級(jí)配砂石或天然砂回填標(biāo)高。超挖部分回填后壓實(shí)，其密實(shí)度應(yīng)接近原地基天然土的密實(shí)度。

(4) Local over excavation should be backfilled and compacted. When there is no groundwater at the bottom of the ditch, if the over excavation is within 0.15m, the original soil can be used for backfilling; If the excavation exceeds 0.15m, lime soil can be used for treatment. When there is groundwater or a large amount of water at the bottom of the ditch, graded sand or natural sand should be used to backfill to the elevation. The over excavated part should be compacted after backfilling, and its compactness should be close to that of the original natural soil of the foundation.

(5)在濕陷性黃土地區(qū)，不宜在雨期施工，或在施工時(shí)切實(shí)排除溝內(nèi)積水，開挖時(shí)應(yīng)在溝底預(yù)留值0.03~0.06m厚的土層進(jìn)行壓實(shí)處理。

(5) In collapsible loess areas, it is not advisable to construct during rainy periods or effectively drain the accumulated water in the ditch. During excavation, a soil layer with a thickness of 0.03-0.06m should be reserved at the bottom of the ditch for compaction treatment.

(6)溝底遇有廢棄構(gòu)筑物、硬石、木頭、垃圾等雜物時(shí)必須，并應(yīng)鋪一層厚度不小于0.15m砂土或素土，整平壓實(shí)及設(shè)計(jì)標(biāo)高。

(6) When encountering abandoned structures, hard stones, wood, garbage and other debris at the bottom of the ditch, they must be removed, and a layer of sand or plain soil with a thickness of not less than 0.15m should be laid, leveled and compacted to the design elevation.

(7)對(duì)軟土基及特殊腐蝕土壤，應(yīng)按設(shè)計(jì)要求處理。

(7) Soft soil foundation and special corrosive soil should be treated according to design requirements.

2.回填土。

2. Backfill soil.

(1)不得采用凍土、垃圾、木材及軟性物質(zhì)回填。管道兩側(cè)及管頂以上0.5m內(nèi)的回填土，不得含有碎石、磚塊等雜物，且不得采用灰土回填。距管頂0.5m以上的回填土中的石塊不得多于10%、直徑不得大于0.1m,且均勻分布。

(1) Frozen soil, garbage, wood, and soft materials shall not be used for backfilling. The backfill soil on both sides of the pipeline and within 0.5m above the pipe top shall not contain debris such as crushed stones and bricks, and shall not be backfilled with lime soil. The stones in the backfill soil at a distance of more than 0.5m from the pipe top shall not exceed 10%, and the diameter shall not exceed 0.1m, and shall be evenly distributed.

(2)溝槽的支撐應(yīng)在管道兩側(cè)及管頂以上0.5m回填完畢并壓實(shí)后，在保證的情況下進(jìn)行拆除，并應(yīng)采取細(xì)砂填實(shí)縫隙。

(2) The support of the trench should be backfilled and compacted on both sides of the pipeline and 0.5m above the pipe top, and then removed while ensuring safety. Fine sand should be used to fill the gaps.

(3)溝槽回填時(shí)，應(yīng)先回填管底懸空部位，再回填管道兩側(cè)。

(3) When backfilling the trench, the suspended area at the bottom of the pipe should be backfilled first, and then both sides of the pipe should be backfilled.

(4)回填土應(yīng)分層壓實(shí)，每層虛鋪厚度宜為0.2~0.3m，管道兩側(cè)及管頂以上0.5m內(nèi)的回填土必須采用人工壓實(shí)，管頂0.5m以上的回填土可采用小型機(jī)械壓實(shí)，每層虛鋪厚度宜為0.25~0.4m。

(4) The backfill soil should be compacted in layers, with a virtual paving thickness of 0.2-0.3m for each layer. The backfill soil on both sides of the pipeline and within 0.5m above the pipe top must be manually compacted. The backfill soil above 0.5m above the pipe top can be compacted by small machinery, and the virtual paving thickness of each layer should be 0.25-0.4m.

(5)回填土壓實(shí)后，應(yīng)分層檢查密實(shí)度，并做好回填記錄。

(5) After the backfilling soil is compacted, the compactness should be checked in layers and backfilling records should be kept.

3.警示帶鋪設(shè)。

3. Laying of warning tape.

(1)埋設(shè)燃?xì)夤艿赖难鼐€應(yīng)連續(xù)鋪設(shè)警示帶。警示帶鋪設(shè)前應(yīng)將鋪設(shè)面壓實(shí)，并平整的鋪設(shè)在管道的正上方，距管的距離宜為0.3~0.5m，但不得鋪設(shè)于路基和路面內(nèi)。

(1) Warning tapes should be continuously laid along the buried gas pipelines. Before laying the warning tape, the surface should be compacted and laid flat above the pipeline. The distance from the pipeline should be 0.3~0.5m, but it should not be laid in the roadbed or road surface.

(2)警示帶宜采用黃色聚乙烯等不易分解的材料，并印有明顯、牢固的警示語(yǔ)，字體不應(yīng)小于100*100mm。以上就是金能電力為您介紹的燃?xì)夤艿谰編У幕局R(shí)了，主要從規(guī)格、作用、埋設(shè)三個(gè)方面為您介紹，希望對(duì)您有所幫助!

(2) The warning tape should be made of materials that are not easily decomposed, such as yellow polyethylene, and printed with clear and firm warning messages. The font should not be less than 100 * 100mm. The above is the basic knowledge of the gas pipeline warning tape introduced by Jinneng Power to you, mainly from three aspects: specifications, functions, and burial. We hope it can be helpful to you!
