一、地埋電纜常見問題

1、 Common problems with buried cables

地下電纜作為城市重要的基礎設施之一，被廣泛應用于電力、通訊、天然氣等領域。但隨著城市建設的不斷發展，地下電纜也面臨著一系列的問題：

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. 施工損壞：由于未標明地下電纜布置情況，在施工過程中易被損壞，同時也增加了施工成本；

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. 誤傷人員：未設立電纜警示標志易造成人員被誤傷的情況；

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

3. 維護困難：地下電纜被安置在深埋地下，一旦發生故障，排查和維護均需要大量時間和人力。

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、地埋電纜警示樁國標規范

2、 National standard specification for warning piles for buried cables

地埋電纜警示樁是地下電纜敷設過程中必不可少的設施之一。為了提高地下電纜的保護水平，標準制定了《地埋電纜警示標志及其應用》（GB/T 50313-2018）標準。

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.

該國標規范了地埋電纜警示標志的要求、設計、施工及管理等方面的內容，具體包括：

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

1. 地埋電纜警示標志是將警示信息標識在地上的設施，標志的形式可以采用磚墩、柱子、標志牌等形式；

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. 設計要求：警示標志應與地下電纜垂直設置，標志文字與標準色應符合標準；

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：地埋電纜警示標志施工前，需要進行現場勘測、環境影響分析等，施工后應進行驗收及日常維護；

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：設置地埋電纜警示標志的單位，需要進行定期巡查、檢查，及時發現和處理問題。

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、實施地埋電纜警示樁的方法

3、 Method of implementing warning piles for buried cables

1. 現場勘測：對于地下電纜的敷設走向和現場情況等進行勘測，確定地埋電纜警示標志的數量和位置；

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. 設計標志方案：制定符合標準，并適應現場實際的電纜警示標志方案，如圖案、顏色、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. 施工建設：選擇符合品質要求的警示標志材料，按照標準施工排布電纜警示標志；

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

4. 養護維修：定期對電纜警示標志進行巡查、清洗、養護和維修等工作，確保其功能正常。

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