由于隨著社會經濟不斷發展，地下管網建設中越來越多地采用PE、PPR、PVC等塑料管，探測儀器根本無法探測到管線走向，可探測警示帶可以管線無法探測這一難題(有帶不銹鋼、銅、鋁、鋁箔、鉑、鋅、鉛等金警示帶)。

With the continuous development of social economy, PE, PPR, PVC and other plastic pipes are increasingly used in the construction of underground pipe networks. The detection instrument can not detect the direction of the pipeline at all. The problem that the pipeline cannot be detected can be solved by the detectable warning tape (including stainless steel, copper, aluminum, aluminum foil, platinum, zinc, lead and other gold warning tapes).

廣泛使用：

Widely used:

城市給排水、熱力、自來水排污、直埋式可探測管道、輸油管道、電力(高壓、低壓、)通訊電纜光纜(電信、移動、聯通、鐵通、網絡、廣播電視)等關于國計民生的第五類運輸體系及信息傳輸系統的警示防護。

Urban water supply and drainage, heating, tap water drainage, directly buried detectable pipelines, oil pipelines, electric power (high-voltage, low-voltage), communication cables and optical cables (telecommunications, mobile, China Unicom, China Railway, network, radio and television) and other fifth class transportation systems and information transmission systems related to the national economy and the people's livelihood.

在施工與埋管同時進行，埋覆于地面與管線中間，起到標志警示、探測管位等作用，避免誤挖損壞管線。特別對各種情況復雜的城市管網施工現場、道路施工現場、田野中的直埋管線有著明顯的防護警示作用。

The construction and pipe burying shall be carried out at the same time, and it shall be buried between the ground and the pipeline, which plays the role of marking and warning, detecting the pipe position and so on, so as to avoid damaging the pipeline by mistake. In particular, it has an obvious protective and warning effect on the directly buried pipelines in various complex urban pipe network construction sites, road construction sites and fields.

作用：

effect:

當開挖施工時，如挖到可探測警示帶，則表示在下方0.30.5米處有可探測管道，起到了警示和保護作用。示蹤作用。尋找地埋可探測管道時，找到警示帶即找到了管道，起到了示蹤作用。現在的警示帶有示蹤線，利用測試儀器在不開挖的情況下，準確為管道定位。

During excavation, if a detectable warning tape is found, it means that there is a detectable pipeline 0.3 to 0.5 meters below, which plays a role of warning and protection. Tracer effect. When looking for buried detectable pipelines, finding the warning tape means finding the pipeline, which plays a role of tracing. The current warning has a tracer line, and the test instrument is used to accurately locate the pipeline without excavation.

埋設可探測管道的沿線應連續鋪設警示帶。警示帶鋪設前應將鋪設面壓實，并平整的鋪設在管道的正上方，距管定的距離宜為0.3~0.5m，但不得鋪設于路基和路面內。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，字體不應小于100*100mm。

Warning tapes shall be continuously laid along the lines where detectable pipelines are buried. Before laying the warning tape, the laying surface shall be compacted and laid flat directly above the pipe. The distance from the pipe should be 0.3~0.5m, but it shall not be laid in the subgrade and pavement. The warning tape should be made of yellow polyethylene and other materials that are not easy to decompose, and printed with obvious and firm warning words. The font should not be less than 100*100mm.

注意：

be careful:

不得采用凍土、垃圾、木材及軟性物質回填。管道兩側及管頂以上0.5m內的回填土，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。

Frozen soil, garbage, wood and soft materials shall not be used for backfilling. The backfill on both sides of the pipeline and within 0.5m above the pipe top shall not contain debris, bricks and other debris, and shall not be backfilled with lime soil. The stones in the backfill soil above 0.5m from the pipe top shall not be more than 10%, and the diameter shall not be more than 0.1M, and shall be evenly distributed.

溝槽的支撐應在管道兩側及管頂以上0.5m回填完畢并壓實后，在保證的情況下進行拆除，并應采取細砂填實縫隙。溝槽回填時，應先回填管底懸空部位，再回填管道兩側。

The support of the trench shall be backfilled and compacted on both sides of the pipe and 0.5m above the pipe top, and then removed under the condition of ensuring safety, and the gap shall be filled with fine sand. When backfilling the trench, the suspended part at the bottom of the pipe shall be backfilled first, and then both sides of the pipe shall be backfilled.

回填土應分層壓實，每層虛鋪厚度宜為0.2~0.3m，管道兩側及管頂以上0.5m內的回填土須采用人工壓實，管頂0.5m以上的回填土可采用小型機械壓實，每層虛鋪厚度宜為0.25~0.4m。

The backfill soil shall be compacted in layers, and the virtual 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 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.
