燃气标记桩20米一个
。现在自然气正在普及，有利就有弊，自然气也是一种危险的气体，在装置的历程中施工队一定要小心再小心
。为了阻止其它施工方在举行现场施工的时间不造成危险，以是在装置燃气管道的上方距离20米装置一根燃气标记桩，以起到警示作用
。

　　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.

　　注重事项

　　matters needing attention

　　燃气标记桩在设置时，有两种情形，一种是上方可以装置，接纳在管道的正上方装置，一种是当管道正上方没有装置条件，但必需装置时，可设置在相对距离较近的路边绿化带内，但要在燃气标记桩上设置管道走向简图，指明管道的详细位置，燃气标记桩的装置间距要求以便于视察为原则，思量到经济性和适用性
。

　　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.
