燃气标志桩在人们的生活和城市的供气中起着非常重要的作用。如果天然气管道被挖断，后果将不堪设想。

Gas marker posts play a very important role in people's lives and the safe gas supply of cities. If the natural gas pipeline is cut off, the consequences will be unimaginable.

埋设在天然气高压管线沿线，涂有黄色标记、横断面有15公分大小，总长1米多而露出地面约60公分左右的标志桩，标志桩上设有“燃气管道、燃气电话、管线桩号、管线走向、电子巡检信息钮”，设置标志桩可以起到提示和警示作用。

It is buried along the natural gas high-pressure pipeline, painted with yellow marks, with a cross-section of 15 cm in size and a total length of more than 1 meter, and about 60 cm above the ground. The sign pile is equipped with "gas pipeline, gas telephone, pipeline pile number, pipeline direction, electronic Patrol information button". Setting the sign pile can play a role of prompt and warning.

巡线抢修人员可以对照标志桩上的“电子巡检信息钮、管线走向、管线桩号”。迅速找准管线位置、明确走向并及时采取措施，从而赢得抢修时机，快速应急处置。

The line patrol and emergency repair personnel can compare the "electronic Patrol information button, pipeline direction and pipeline pile number" on the sign pile. Quickly identify the location of the pipeline, clarify the direction and take measures in time, so as to win the opportunity of emergency repair and rapid emergency disposal.

如涉及高压管线区域施工，作业单位可以及时得到提示及联系方式。避开高压管线，避免高压管线被盲目挖伤、穿越碰伤，物探损伤造成的管线损坏现象，达到维护供气的目的。

If the construction of high-pressure pipeline area is involved, the operation unit can get prompt and contact information in time. Avoid high-pressure pipelines, and avoid pipeline damage caused by blind excavation, crossing and bumping of high-pressure pipelines, and geophysical damage, so as to achieve the purpose of maintaining gas supply safety.

燃气标志桩在设置时，有两种情况，一种是上方可以安装，采取在管道的正上方安装。一种当管道正上方没有安装条件，但必须安装时，可设置在相对距离较近的路边绿化带内。但要在标志桩上设置管道走向简图，指明管道的具体位置。

There are two situations when setting the gas marker post. One is that it can be installed above the pipeline, which is installed directly above the pipeline. When there is no installation condition directly above the pipeline, but it must be installed, it can be set in the roadside green belt that is relatively close. However, a pipeline route diagram shall be set on the sign pile to indicate the specific location of the pipeline.

标志桩的安装间距要求以便于观察为原则，考虑到经济性和实用性，由于野外视野比较好，结合目前企业实际应用情况，以50 ~80m为宜，对于标志桩的高度，考虑到便于观察，可以适当高一些，实际运用中，对于街坊管处的标志桩可以适当低一些，不作具体规定，各公司根据具体情况自行决定。

The installation spacing of sign piles shall be based on the principle of easy observation. Considering the economy and practicality, due to the good field vision and combined with the current actual application of enterprises, it is appropriate to take 50 ~ 80m as the height of sign piles. Considering the convenience of observation, it can be appropriately higher. In practical application, the sign piles at the neighborhood management can be appropriately lower without specific regulations, and each company will decide on its own according to the specific situation.

标志桩上的内容很多，其内容大致分为对内、对外信息，对外信息是标志桩设置的根本目的，所以必须包括管道权属单位名称、警示用语联系电话，告知管道权属单位名称、联系电话，可方便其他施工企业施工时联系或当发生意外时市民能及时通知管道权属单位。警示用语可包括“下有燃气管道，严禁开挖”、“保护管道，人人有责”等，起到警示宣传作用，对于信息包括标志桩、管道区域名称、企业标识等，企业自行掌握，不做严格要求。

There are many contents on the sign pile, which can be roughly divided into internal and external information. External information is the fundamental purpose of the sign pile setting, so it must include the name of the pipeline ownership unit, warning words and contact number. Informing the name and contact number of the pipeline ownership unit can facilitate other construction enterprises to contact during construction or citizens to notify the pipeline ownership unit in time in case of accidents. Warning words can include "no excavation under gas pipelines", "everyone is responsible for protecting pipelines", etc., which plays a role of warning and publicity. The information, including sign piles, pipeline area names, enterprise logos, etc., is controlled by the enterprise itself and is not strictly required.

燃气标志桩的颜色选取基于以下考虑，要清晰明了，方便观察，其次在颜色的选取要突出燃气行业的标志桩，与其他行业的标志桩有所区别，标识内容应清晰，宜两年刷漆一次。

The color selection of gas marker post is based on the following considerations. First, it should be clear and easy to observe. Secondly, in the selection of color, it should highlight the marker post of gas industry, which is different from that of other industries. The content of the sign should be clear and should be painted once every two years.
