　　Each gas marker post is 20 meters long. Nowadays, natural gas is becoming popular, and there are advantages and disadvantages. Natural gas is also a dangerous gas, and the construction team must be careful during the installation process. In order to prevent other construction parties from causing danger during on-site construction, a gas marker post is installed every 20 meters above the installation of the gas pipeline to serve as a warning.

　　註意事項

　　matters needing attention

　　燃氣標誌樁(zhuang)在(zai)設(she)置(zhi)時，有兩(liang)種情況(kuang)，壹種(zhong)是上方(fang)可以安裝(zhuang)，采取在(zai)管(guan)道(dao)的正(zheng)上方(fang)安(an)裝(zhuang)，壹種(zhong)是當(dang)管(guan)道(dao)正上方(fang)沒(mei)有(you)安(an)裝(zhuang)條件，但必須(xu)安(an)裝(zhuang)時，可設置在相(xiang)對距離(li)較近的路(lu)邊綠(lv)化(hua)帶(dai)內，但(dan)要(yao)在燃氣標誌樁(zhuang)上設(she)置(zhi)管(guan)道(dao)走(zou)向簡(jian)圖，指(zhi)明管(guan)道(dao)的具(ju)體位置(zhi)，燃氣標誌樁(zhuang)的安(an)裝(zhuang)間(jian)距要(yao)求(qiu)以便於觀(guan)察(cha)為原(yuan)則(ze)，考慮(lv)到經濟(ji)性(xing)和(he)實(shi)用(yong)性(xing)。

　　When setting up gas marker piles, there are two situations: one is that they can be installed above the pipeline and should be installed directly above it; the other is that when there are no installation conditions above the pipeline but installation is necessary, they can be set up in a relatively close roadside green belt. However, a schematic diagram of the pipeline direction should be set up on the gas marker pile, indicating the specific location of the pipeline. The installation spacing of gas marker piles should be based on the principle of easy observation, considering economy and practicality.
