高压天然气管线警示标记

来源:/ 宣布时间:日期:2024-03-17 0

一、管线标记桩

1、 Pipeline marker pile

管道沿线设置的标记桩是直观、有效的向人们通报管道;ば畔⒌脑靥。高压天然气管道的标记桩,地上部分高度超1m(如图1所示),上面包括管线的权属单位名称、管道的走向、联系电话等信息。标记桩一般在转角位置与较为重要显眼的部位埋设,沿着标记桩可以掌握大致的管线位置与走向?吹奖昙亲渌镜牡叵鹿芟哐叵5m规模是禁止动土开挖的,如有交叉施工或临近的紧急情况请拨打桩上的联系电话。

The marker stakes set up along the pipeline are a visual and effective carrier for conveying pipeline protection information to people. The marker post for high-pressure natural gas pipelines has a height of over 1m above ground (as shown in Figure 1), which includes information such as the name of the pipeline's owner, pipeline direction, and contact phone number. Sign stakes are usually buried at corners and prominent areas, and along the sign stakes, one can roughly grasp the position and direction of the pipeline. It is prohibited to excavate the underground pipeline within a 5m range along the marked pile. If there is cross construction or adjacent emergency situations, please call the contact phone number on the pile.

二、通信管线标记桩

2、 Communication pipeline marker post

通信管线标记桩用于指示高压天然气管线的通信光缆位置,通信光缆接纳硅管,部分非开挖接纳PE套管;,内含独立光缆用于站内通信数据传输与应急响应。通信标记桩约0.5米高,上面包括管线的权属单位,管线走向以及联系电话等。通信光缆关于管线运行意义重大,如果造成以外破坏将对管线运营造成较大影响。

The communication pipeline marker post is used to indicate the position of communication optical cables for high-pressure natural gas pipelines. The communication optical cables are made of silicon pipes, and some non excavation parts are protected by PE sleeves. It contains independent optical cables for communication data transmission and emergency response within the station. The communication marker post is about 0.5 meters high and contains the ownership unit of the pipeline, pipeline direction, and contact phone number. Communication optical cables are of great significance for pipeline operation, and if external damage is caused, it will have a significant impact on pipeline operation.

三、管线警示牌

3、 Pipeline warning signs

管线警示牌为通体黄色,地上高度1.5m左右,主要安顿于重要的过河过路环节,警示牌上显示了警示口号【下有天然气管线,禁止挖掘、打桩、明火,若有施事情业请事先联系】、以红线描述管线在地下的走线、权属单位名称、联系电话等。另一种不锈钢管线警示牌(如图4所示)为白底红字,主要安排在管线易泛起交叉的部位与路口,警示内容包括【严禁在天然气高压管道沿线两侧各5米地区规模内开挖、种植深根植物、钻洞穿越、辗压、动火、爆破作业等种种危险行为】、权属单位名称、联系电话等。

The pipeline warning sign is yellow throughout the body, with a height of about 1.5m above ground. It is mainly installed in important river crossing links. The warning sign displays warning slogans such as "There are natural gas pipelines below, excavation, piling, and open flames are prohibited. If there are construction operations, please contact them in advance", and describe the underground routing of the pipeline with a red line, the name of the ownership unit, and the contact phone number. Another type of stainless steel pipeline warning sign (as shown in Figure 4) is a white background with red letters, mainly placed in key areas and intersections where pipeline intersections are prone to occur. The warning content includes: excavation, planting of deep rooted plants, drilling through holes, rolling, hot work, blasting operations, and other dangerous behaviors are strictly prohibited within a range of 5 meters on each side of the natural gas high-pressure pipeline. The name and contact phone number of the ownership unit are also included.

四、管线阴保桩

4、 Pipeline cathodic protection pile

管线阴保桩是埋设在管线四周,对管道进行;さ闹匾郊。他既可以;す艿赖姆栏,也能用于线路的检测,是天然气管线的重要附件之一。阴保桩为金属材质,颜色为黄色,桩顶部扁平处有不锈钢标牌,上面印有相关编号与里程号。桩身上有一扇小门,里面的线缆与管道相连。

Pipeline cathodic protection piles are important accessories buried near pipelines to protect them. He can not only protect the anti-corrosion layer of pipelines, but also be used for line inspection, and is one of the important accessories of natural gas pipelines. The cathodic protection pile is made of metal material and has a yellow color. There is a stainless steel sign on the flat top of the pile, which is printed with the relevant number and mileage number. There is a small door on the pile body, and the cables inside are connected to the pipeline.

五、管线过河指示牌

5、 Pipeline crossing sign

管线大型重要指示牌主要安排在管线穿越重要河流的两岸,其警示内容包括:【禁止在穿越河流的管道两侧500米地区规模内进行疏浚、修筑码头,抛拖锚、挖泥沙、打桩、采石、水下爆破等种种违规作业】、联系电话、权属单位名称等。高压天然气管线穿越河流的品级较高,指示牌主要安排在显眼位置,如有临近的施工,需要提前进行对接。

Large and important signs for pipelines are mainly placed on both sides of important rivers where the pipeline crosses. The warning content includes: "Dredging, building docks, throwing and dragging anchors, digging mud and sand, piling, quarrying, underwater blasting and other illegal operations are prohibited within a 500 meter area on both sides of the pipeline crossing the river." Contact phone number, name of the owner unit, etc. The safety level of high-pressure natural gas pipelines crossing rivers is relatively high, and signs are mainly placed in prominent positions. If there is nearby construction, it is necessary to connect in advance.

六、管线警示带

6、 Pipeline warning tape

凭据要求,开挖敷设的高压天然气管线需在管线正上方铺设警示带警示带为宽度约0.5m,颜色为警示黄色,警示带上内容包括禁止挖掘的警示口号、管线权属单位名称以及联系电话。为了;ぬ烊黄芟叩,如果现场开挖发明管线警示带,需要立刻停止施工并拨打其上方所写的联系电话进行确认,期待人员加入确认后再按要求进行施工。

According to the requirements, a warning tape with a width of about 0.5m and a color of yellow should be laid directly above the high-pressure natural gas pipeline during excavation. The content of the warning tape includes warning slogans prohibiting excavation, the name of the pipeline owner, and the contact phone number. In order to protect the safety of natural gas pipelines, if a warning tape is found during on-site excavation, construction needs to be stopped immediately and the contact phone number written above should be dialed for confirmation. Construction can only be carried out as required after professional personnel arrive to confirm.
