壹、結(jie)構
電纜警示(shi)帶(dai)由(you)底膜、面膜和(he)鋁(lv)箔(bo)組成(cheng)，底膜與(yu)面膜(mo)、底膜與(yu)鋁箔(bo)結(jie)合(he)牢(lao)固(gu)，並整(zheng)體滾(gun)花(hua)成(cheng)型(xing)。The cable warning tape is composed of a bottom film, a surface film and aluminum foil. The bottom film is firmly combined with the surface film and the aluminum foil, and is integrally embossed.
蹤(zong)跡(ji)電纜警示(shi)帶(dai)印(yin)有醒目(mu)、性(xing)的(de)警(jing)示(shi)語，不(bu)掉色、不(bu)褪(tui)色。The trace cable warning tape is printed with eye-catching and permanent warning words, without fading or discoloration.
二(er)、物(wu)理性(xing)能
- 蹤(zong)跡電纜警示(shi)帶(dai)每卷內無(wu)接(jie)頭(tou)。There is no joint in each roll of trace cable warning tape.
- 蹤(zong)跡(ji)電纜警示(shi)帶(dai)兩(liang)層(ceng)塑料薄(bo)膜(mo)的(de)剝(bo)離(li)強(qiang)度(du)應大(da)於(yu) 0.10N/mm（拉(la)伸(shen)速(su)度 25mm/min）。The peel strength of the two layers of plastic film of the trace cable warning tape should be greater than 0.10N/mm (tensile speed 25mm/min).
- 每卷蹤(zong)跡(ji)電纜警示(shi)帶(dai)應通(tong)電導通(tong)，電阻小(xiao)於(yu) 20Ω/100m（用歐(ou)姆(mu)表檢(jian)測(ce)）。Each roll of trace cable warning tape should be electrically conductive, and the resistance is less than 20Ω/100m (detected by an ohmmeter).
- 蹤(zong)跡電纜警示(shi)帶(dai)的(de)延(yan)伸(shen)率(lv)≥25％。The elongation rate of the trace cable warning tape is ≥25%.
三、敷(fu)設(she)
- 蹤跡電纜警示(shi)帶(dai)敷(fu)設(she)在管頂(ding)上方(fang) 300 - 500mm 處（以保證(zheng)施工挖(wa)出蹤跡(ji)帶(dai)時(shi)，傷(shang)害不(bu)到管線），但不(bu)得(de)敷設(she)於(yu)路基或(huo)路面(mian)裏(li)。The trace cable warning tape is laid at 300 - 500mm above the pipe top (to ensure that the pipeline will not be damaged when the trace tape is excavated during construction), but it must not be laid in the subgrade or pavement.
- 直徑(jing)不(bu)大(da)於(yu) 400mm 的(de)管道(dao)，可(ke)在上方(fang)敷(fu)設(she)壹條(tiao)蹤(zong)跡電纜警示(shi)帶(dai)；大(da)於(yu) 400mm 的(de)管道(dao)，應在管道(dao)正(zheng)上方(fang)平(ping)行(xing)敷設兩條水(shui)平(ping)凈(jing)距 100 - 200mm 的(de)蹤(zong)跡(ji)電纜警示(shi)帶(dai)。For pipelines with a diameter of not more than 400mm, one trace cable warning tape can be laid above; for pipelines larger than 400mm, two trace cable warning tapes with a horizontal clear distance of 100 - 200mm should be laid in parallel directly above the pipeline.
- 敷(fu)設(she)過(guo)程(cheng)中，兩(liang)條(tiao)蹤(zong)跡電纜警示(shi)帶(dai)連接(jie)處應搭接(jie) 1 米(mi)左(zuo)右，搭接(jie)處將(jiang)鋁(lv)箔壹側的(de) PE 膜(mo)剝(bo)開，露(lu)出鋁箔(bo)，使(shi)兩(liang)條蹤(zong)跡帶(dai)的(de)鋁(lv)箔(bo)充(chong)分接(jie)觸(chu)，並用塑料膠帶(dai)將(jiang)搭接(jie)部(bu)分整(zheng)體包(bao)裹(guo)嚴實(shi)，保證(zheng)粘接(jie)牢(lao)固(gu)，通電後能導(dao)通(tong)。During the laying process, the connection of two trace cable warning tapes should be overlapped by about 1 meter. At the overlap, peel off the PE film on the aluminum foil side to expose the aluminum foil, so that the aluminum foils of the two trace tapes are in full contact. Then, use plastic tape to tightly wrap the overlapped part as a whole to ensure firm bonding and conductivity after being energized.
- 在 PE 管管端(duan)，若(ruo)蹤跡(ji)帶(dai)沒有引(yin)出地(di)面(mian)，則應將(jiang)蹤(zong)跡帶(dai)剝(bo)開 50 厘米(mi)長，讓(rang)鋁(lv)箔(bo)與(yu)大(da)地(di)充(chong)分接(jie)觸(chu)，鋁箔(bo)與(yu)大(da)地(di)形(xing)成(cheng)回路，減少接(jie)觸(chu)電阻，可(ke)以(yi)提(ti)高探測(ce)質量(liang)。At the end of the PE pipe, if the trace tape is not led out of the ground, the trace tape should be peeled off for 50 centimeters long to allow the aluminum foil to fully contact the ground. The aluminum foil and the ground form a circuit to reduce contact resistance and improve detection quality.
- 敷設過(guo)程(cheng)中可(ke)設(she)置(zhi)信號(hao)源井，將(jiang)蹤(zong)跡帶(dai)引(yin)出，留在井內 1 米(mi)，便(bian)於(yu)探測(ce)時(shi)用。During the laying process, a signal source well can be set up to lead out the trace tape and leave it in the well for 1 meter for use during detection.
- 蹤跡帶(dai)整(zheng)體滾(gun)花(hua)成(cheng)型(xing)並(bing)成(cheng)卷放(fang)置(zhi)、運(yun)輸，蹤跡(ji)帶(dai)開卷後會(hui)不(bu)平(ping)展。施工時(shi)，把(ba)蹤(zong)跡帶(dai)打開 4 - 5 米(mi)，兩(liang)個人用手抓(zhua)住兩(liang)端(duan)用力拉(la)平(ping)，松手後蹤跡(ji)帶(dai)便(bian)會(hui)平(ping)展。然(ran)後再進行(xing)敷設。The trace tape is integrally embossed and placed and transported in rolls. After the trace tape is unrolled, it will not be flat. During construction, open the trace tape for 4 - 5 meters. Two people hold the two ends with their hands and pull it flat hard. After releasing their hands, the trace tape will be flat. Then lay it.
- 局部(bu)超挖部(bu)分應回(hui)填夯(hang)實(shi)。當溝(gou)底無(wu)地(di)下(xia)水(shui)時(shi)，超挖在 0.15m 以內，可(ke)采(cai)用原(yuan)土回填；超挖在 0.15m 以上，可(ke)采(cai)用石灰(hui)土處理。當溝(gou)底有地(di)下(xia)水(shui)或(huo)水(shui)量(liang)較大(da)時，應采(cai)用級配砂(sha)石或(huo)天然砂(sha)回(hui)填標(biao)高。超挖部(bu)分回填後壓實(shi)，其密(mi)實(shi)度應接(jie)近(jin)原(yuan)地(di)基天(tian)然(ran)土的(de)密(mi)實(shi)度。The locally over-excavated part 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 over-excavation is more than 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 and gravel or natural sand should be used to backfill to the elevation. After the over-excavated part is backfilled, it should be compacted, and its compactness should be close to that of the natural soil of the original foundation.
- 在濕陷(xian)性(xing)黃土地(di)區(qu)，不(bu)宜在雨期施工，或(huo)在施工時(shi)切(qie)實(shi)排除溝(gou)內積(ji)水(shui)，開挖時應在溝(gou)底預留值 0.03 - 0.06m 厚(hou)的(de)土層(ceng)進行(xing)壓實(shi)處理。In collapsible loess areas, it is not suitable to construct during the rainy season. Or during construction, the accumulated water in the ditch should be effectively drained. When excavating, a soil layer with a thickness of 0.03 - 0.06m should be reserved at the bottom of the ditch for compaction treatment.
- 溝(gou)底遇(yu)有廢棄構築物(wu)、硬石、木(mu)頭、垃(la)圾等(deng)雜物(wu)時必(bi)須(xu)，並應鋪壹層(ceng)厚度(du)不(bu)小(xiao)於(yu) 0.15m 砂(sha)土或素(su)土，整(zheng)平壓實(shi)及(ji)設計(ji)標(biao)高。When there are abandoned structures, hard stones, wood, garbage and other sundries at the bottom of the ditch, they must be removed. A layer of sand or plain soil with a thickness of not less than 0.15m should be laid, leveled, compacted and designed elevation.
- 不(bu)得(de)采(cai)用凍土、垃(la)圾、木材(cai)及(ji)軟性(xing)物(wu)質回填。管道(dao)兩(liang)側及(ji)管頂(ding)以上 0.5m 內的(de)回(hui)填土，不(bu)得(de)含(han)有碎石、磚(zhuan)塊(kuai)等(deng)雜物(wu)，且不(bu)得(de)采(cai)用灰土回填。距(ju)管頂(ding) 0.5m 以上的(de)回(hui)填土中的(de)石塊(kuai)不(bu)得(de)多(duo)於(yu) 10%、直徑(jing)不(bu)得(de)大(da)於(yu) 0.1m，且均勻分布。Frozen soil, garbage, wood and soft substances 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 gravel and bricks, and lime soil shall not be used for backfilling. The stones in the backfill soil more than 0.5m above the pipe top shall not be more than 10%, and the diameter shall not be greater than 0.1m and be evenly distributed.
- 回(hui)填土應分層(ceng)壓實(shi)，每層(ceng)虛鋪厚度(du)宜為 0.2 - 0.3m，管道(dao)兩(liang)側及(ji)管頂(ding)以上 0.5m 內的(de)回(hui)填土必(bi)須(xu)采(cai)用人工壓實(shi)，管頂(ding) 0.5m 以上的(de)回(hui)填土可(ke)采(cai)用小型(xing)機(ji)械壓實(shi)，每層(ceng)虛鋪厚度(du)宜為 0.25 - 0.4m。The backfill soil should be compacted in layers. The loose paving thickness of each layer should be 0.2 - 0.3m. The backfill soil on both sides of the pipeline and within 0.5m above the pipe top must be compacted manually. The backfill soil more than 0.5m above the pipe top can be compacted by small machinery. The loose paving thickness of each layer should be 0.25 - 0.4m.
- 埋(mai)設燃(ran)氣管道(dao)的(de)沿(yan)線應連續(xu)鋪設警(jing)示(shi)帶(dai)。警(jing)示(shi)帶(dai)鋪設前(qian)應將(jiang)鋪設面(mian)壓實(shi)，並平(ping)整(zheng)的(de)鋪設在管道(dao)的(de)正(zheng)上方(fang)，距(ju)管頂(ding)的(de)距(ju)離(li)宜為 0.3 - 0.5m，但不(bu)得(de)鋪設於(yu)路基和(he)路面(mian)內。Along the line where the gas pipeline is buried, warning tapes should be laid continuously. Before laying the warning tape, the laying surface should be compacted and laid flat directly above the pipeline. The distance from the pipe top should be 0.3 - 0.5m, but it must not be laid in the subgrade or pavement.
