一、地埋电缆常见问题

1、 Common problems with buried cables

地下电缆作为城市重要的基础设施之一，被广泛应用于电力、通讯、天然气等领域。但随着城市建设的不断发展，地下电缆也面临着一系列的问题：

Underground cables, as one of the important infrastructure in cities, are widely used in fields such as electricity, communication, and natural gas. But with the continuous development of urban construction, underground cables also face a series of problems:

1. 施工损坏：由于未标明地下电缆布置情况，在施工过程中易被损坏，同时也增加了施工成本；

1. Construction damage: Due to the lack of indication of underground cable layout, it is easy to be damaged during the construction process and also increases construction costs;

2. 误伤人员：未设立电缆警示标志易造成人员被误伤的情况；

2. Accidental injury to personnel: Failure to set up cable warning signs can easily lead to accidental injury to personnel;

3. 维护困难：地下电缆被安置在深埋地下，一旦发生故障，排查和维护均需要大量时间和人力。

3. Maintenance difficulties: Underground cables are placed deep underground, and once a fault occurs, troubleshooting and maintenance require a lot of time and manpower.

二、地埋电缆警示桩国标规范

2、 National standard specification for warning piles for buried cables

地埋电缆警示桩是地下电缆敷设过程中必不可少的设施之一。为了提高地下电缆的保护水平，标准制定了《地埋电缆警示标志及其应用》（GB/T 50313-2018）标准。

Underground cable warning piles are one of the essential facilities in the process of underground cable laying. In order to improve the safety protection level of underground cables, the Chinese national standard has formulated the "Underground Cable Warning Signs and Their Applications" (GB/T 50313-2018) standard.

该国标规范了地埋电缆警示标志的要求、设计、施工及管理等方面的内容，具体包括：

This national standard specifies the requirements, design, construction, and management of warning signs for buried cables, including:

1. 地埋电缆警示标志是将警示信息标识在地上的设施，标志的形式可以采用砖墩、柱子、标志牌等形式；

1. Underground cable warning signs are facilities that mark warning information on the ground, and the form of the signs can be brick piers, columns, signs, etc;

2. 设计要求：警示标志应与地下电缆垂直设置，标志文字与标准色应符合标准；

2. Design requirements: Warning signs should be set vertically with underground cables, and the text and standard color of the signs should comply with national standards;

3. 施工要求：地埋电缆警示标志施工前，需要进行现场勘测、环境影响分析等，施工后应进行验收及日常维护；

3. Construction requirements: Before the construction of warning signs for buried cables, on-site survey and environmental impact analysis are required. After construction, acceptance and daily maintenance should be carried out;

4. 管理要求：设置地埋电缆警示标志的单位，需要进行定期巡查、检查，及时发现和处理问题。

4. Management requirements: Units that set warning signs for buried cables need to conduct regular inspections and inspections to promptly identify and address issues.

三、实施地埋电缆警示桩的方法

3、 Method of implementing warning piles for buried cables

1. 现场勘测：对于地下电缆的敷设走向和现场情况等进行勘测，确定地埋电缆警示标志的数量和位置；

1. On site survey: Conduct a survey of the laying direction and on-site conditions of underground cables, and determine the number and location of warning signs for buried cables;

2. 设计标志方案：制定符合标准，并适应现场实际的电缆警示标志方案，如图案、颜色、高度等；

2. Design sign scheme: Develop a cable warning sign scheme that complies with national standards and adapts to the actual site conditions, such as patterns, colors, heights, etc;

3. 施工建设：选择符合品质要求的警示标志材料，按照标准施工排布电缆警示标志；

3. Construction: Select warning sign materials that meet quality requirements, and arrange cable warning signs according to the standard construction layout;

4. 养护维修：定期对电缆警示标志进行巡查、清洗、养护和维修等工作，确保其功能正常。

4. Maintenance and repair: Regularly inspect, clean, maintain and repair cable warning signs to ensure their normal function.
