電纜警示帶的結(jié)構(gòu)是由底膜與面膜、底膜與鋁箔結(jié)合牢固，并整體滾花成型。電纜警示帶印有醒目、性的警示語，不掉色、不褪色。下面就來認(rèn)識認(rèn)識電纜警示帶的性能、敷設(shè)和探測相關(guān)內(nèi)容吧。

The structure of the cable warning tape is composed of the bottom film and facial mask, the bottom film and aluminum foil, which are firmly combined and integrally knurled. The cable warning tape shall be printed with eye-catching and permanent warning words, which shall not fade. Let's learn about the performance, laying and detection of cable warning tape.

電纜警示帶的物理性能

Physical performance of cable warning tape

（1）電纜警示帶每卷內(nèi)無接頭。

(1) There is no joint in each roll of cable warning tape.

（2）電纜警示帶兩層塑料薄膜的剝離強度應(yīng)大于0.10N/mm（拉伸速度25mm/min）。

(2) The peel strength of two layers of plastic film of cable warning tape shall be greater than 0.10n/mm (tensile speed: 25mm / min).

（3）每卷電纜警示帶應(yīng)通電導(dǎo)通，電阻小于20Ω/100m（用歐姆表檢測）。

(3) Each reel of cable warning tape shall be electrically conductive with a resistance less than 20 Ω / 100m (detected with an ohmmeter).

（4）電纜警示帶的延伸率≥25％。

(4) The elongation of cable warning tape shall be ≥ 25%.

電纜警示帶的敷設(shè)

Laying of cable warning tape

（1）電纜警示帶敷設(shè)在管頂上方300-500mm處（以保證施工挖出帶時，傷害不到管線），但不得敷設(shè)于路基或路面里。

(1) The cable warning tape shall be laid at 300-500mm above the pipe top (to ensure that the pipeline will not be damaged during the construction of the excavated tape), but shall not be laid in the subgrade or pavement.

（2）直徑不大于400mm的管道，可在上方敷設(shè)一條電纜警示帶；大于400mm的管道，應(yīng)在管道正上方平行敷設(shè)兩條水平凈距100-200mm的電纜警示帶。

(2) A cable warning tape can be laid above the pipe with a diameter of no more than 400mm; For pipes larger than 400mm, two cable warning tapes with a horizontal clear distance of 100-200mm shall be laid in parallel above the pipes.

（3）敷設(shè)過程中，兩條電纜警示帶連接處應(yīng)搭接1米左右，搭接處將鋁箔一側(cè)的PE膜剝開，露出鋁箔，使兩條帶的鋁箔充分接觸，并用塑料膠帶將搭接部分整體包裹嚴(yán)實，保證粘接牢固，通電后能導(dǎo)通

(3) During the laying process, the connection of two cable warning tapes shall be overlapped for about 1m. The PE film on one side of the aluminum foil shall be peeled off at the overlapped place to expose the aluminum foil, so that the aluminum foil of the two tapes can be fully contacted. The overlapped part shall be tightly wrapped with plastic tape to ensure that the bonding is firm and can be conducted after power on

（4）在PE管管端，若帶沒有引出地面，則應(yīng)將帶剝開50厘米長，讓鋁箔與大地充分接觸，鋁箔與大地形成回路，減少接觸電阻，可以提高探測質(zhì)量。

(4) At the end of the PE pipe, if the tape is not led out to the ground, the tape shall be peeled 50 cm long to allow the aluminum foil to fully contact the ground. The aluminum foil and the ground form a loop to reduce the contact resistance and improve the detection quality.

（5）敷設(shè)過程中可設(shè)置信號源井，將帶引出，留在井內(nèi)1米，便于探測時用。等等。

(5) During the laying process, a signal source well can be set up to lead out the belt and leave it in the well for 1m for easy detection. wait.

電纜警示帶的探測

Detection of cable warning tape

電纜警示帶的探測常用的方法是電磁法。電纜警示帶內(nèi)夾帶的金屬箔，在電磁場作用下的感應(yīng)電流會產(chǎn)生二次場。可在地面上用探測儀器探測到，以確定電纜警示帶的位置。

Electromagnetic method is commonly used to detect cable warning tape. The induced current of the metal foil contained in the cable warning tape under the action of the electromagnetic field will generate a secondary field. It can be detected on the ground with a detection instrument to determine the position of the cable warning tape.

例如電磁法主動源法，信號強，定位、定深的精度高，不受臨近其他管道干擾（被查電纜警示帶需有露出點）。

For example, the active source method of electromagnetic method has strong signal, high accuracy of positioning and depth determination, and is not interfered by other nearby pipelines (the warning tape of the inspected cable needs to have an exposure point).

使用時發(fā)射機一端接被查帶，另一端接地或接帶另一端。探測儀通過探測帶產(chǎn)生的磁感應(yīng)強度的變化，確定帶的空間位置。

When in use, one end of the transmitter is connected to the checked tape, and the other end is grounded or connected to the other end of the tape. The detector determines the spatial position of the belt by detecting the change of the magnetic induction intensity generated by the belt.
