How to use gas warning tape

1、檢查是否預(yù)留出了信號接入點，安裝方式是否正確。

1. Check whether the signal access point is reserved and whether the installation method is correct.

2、檢查警示帶中的導(dǎo)電金屬絲是不是可以加載探測信號，有沒有信號泄漏的情況出現(xiàn)，以及是否設(shè)置了足夠的信號檢測井；

2. Check whether the conductive metal wire in the warning tape can load the detection signal, whether there is signal leakage, and whether there are enough signal detection wells;

3、示蹤警示帶安裝好了之后，始端和末端是不是與地面隔離，信號檢測井內(nèi)的警示帶是否進(jìn)行了固定處理；

3. After the tracer warning tape is installed, whether the start and end are isolated from the ground, and whether the warning tape in the signal detection well is fixed;

4、可探測警示帶中的導(dǎo)電金屬絲的直徑是不是滿足應(yīng)用要求，金屬絲直徑太小容易被拉斷，直徑太大則會導(dǎo)致探測信號誤差增大，應(yīng)該選取綜合效果好的直徑。探測信號容易出現(xiàn)的主要問題是信號連續(xù)性易受影響。原因有多種：

4. Whether the diameter of the conductive metal wire in the detectable warning tape meets the application requirements. If the diameter of the metal wire is too small, it is easy to break. If the diameter is too large, it will lead to increased detection signal error. Therefore, the diameter with good comprehensive effect should be selected. The main problem of detection signal is that the signal continuity is easily affected. There are many reasons:

①可能在施工過程中操作失誤導(dǎo)致了警示帶內(nèi)部的導(dǎo)線斷裂，造成了檢測短路；②警示帶的絕緣以及防水處理不夠過關(guān)，導(dǎo)致電線受潮影響探測；③導(dǎo)電金屬絲的直徑過大，造成電阻增大，信號衰減增大，影響探測的效果。

① It is possible that the wire inside the warning tape was broken due to the operation error during the construction, resulting in the detection short circuit; ② The insulation and waterproof treatment of the warning tape are not up to standard, which causes the wire to be affected by moisture and affects the detection; ③ The diameter of the conductive metal wire is too large, which causes the resistance to increase and the signal attenuation to increase, affecting the detection effect.
