The marker post is used as a ground mark to confirm the pipeline route directly above the gas, power and oil pipelines, and as a ground warning sign for the pipeline passing through densely populated areas and other special sections. Optical cable is used to mark the laying position and direction of communication optical cable, also known as optical cable pile. FRP can be used for more than 30 years. Characteristics of pipeline marker pile: the pipeline marker pile is pressed by high temperature, which is resistant to impact, wear, high temperature and corrosion. It can resist water, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium potassium compounds, urine and asphalt, and its service life is up to 30 years. Screen printing technology is adopted for pipeline marker pile, which has good warning effect and does not need maintenance. Light weight, easy to transport and install, no recycling value, natural anti-theft.

标志桩电缆标志桩是电力企业架设、敷设电缆时需要埋设一定距离的警示桩。因此，也称为警示桩。 由于电缆标记桩是一个警告，防止电缆标记桩被埋在多远的地方更合适？太近是浪费资源，太远不是警告。那么，在不浪费资源的情况下，它能起到明显的警告作用，需要多远才能掩埋呢？这次我们请来了我们公司的技术人员。让我给你介绍一下。 其实,规范对电缆线路的施工和验收都有明确的规定。敷设电缆标志杆时，应在直线段、电缆接头、转弯处、进入建筑物等处每隔50~100m设置明显的方向标志或标志杆，这样团队可以起到识别的作用，外部人员可以起到警示和唤醒的作用。 为了更好的发挥警示作用，我们建议如果是在人员流动性较高的地方。建议的间距可以适当减小。这种警示作用是明显的。

Marker post cable marker post is a warning post that needs to be buried at a certain distance when power enterprises erect and lay cables. Therefore, it is also called safety warning pile. Since the cable marker pile is a warning, how far is it more appropriate to prevent the cable marker pile from being buried? Too close is a waste of resources, too far is not a warning. So, without wasting resources, it can play an obvious warning role. How far will it take to bury it? This time we invited our company's technical personnel. Let me introduce you. In fact, the specification has clear provisions on the construction and acceptance of cable lines. When laying cable marker posts, obvious direction signs or marker posts shall be set every 50~100m at straight sections, cable joints, turns, entering buildings, etc., so that the team can play the role of identification, and external personnel can play the role of warning and awakening. In order to better play a warning role, we suggest that if it is in a place with high personnel mobility. The recommended spacing can be reduced appropriately. This warning effect is obvious.
