Precautions for sign posts: Construction workers should wear safety helmets and other labor protection equipment; Set up various eye-catching warning signs within the construction site; We should strengthen on-site safety management and strengthen safety education for employees. The waste soil and materials should be stacked in a neat and orderly manner, and vegetation protection and measures should be taken if necessary to prevent environmental and agricultural pollution caused by soil erosion. After excavation in the soil area, the site is leveled, the slope is trimmed, and vegetation protection is carried out. During construction, measures should be taken to avoid and reduce soil erosion. When soil erosion occurs or causes pollution to farmland and the environment, it should be promptly addressed The temporary construction land will be restored after the land acquisition, meeting the requirements of the contract signed with the lessor and satisfying the lessor. After the completion of the project, remove all debris that occupies the site. Materials left over during construction should be removed.

油氣管道線路標識設置基本要求

Basic requirements for the installation of oil and gas pipeline line markings

相同介質的兩條管道同溝敷設時，線路標識宜合并設置，位置位于兩條管道中間；三條管道同溝敷設時，應分別設置線路標識。

When two pipelines with the same medium are laid in the same trench, the line markings should be merged and placed in the middle of the two pipelines; When three pipelines are laid in the same trench, route markings should be set separately.

不同介質的兩條管道同溝敷設時，應分別設置線路地面標識。

When two pipelines with different media are laid in the same trench, ground markings for the lines should be set separately.

并行管道的線路標識應分別設置，每條管道的線路標識應清晰、醒目、便于區分。

The line markings of parallel pipelines should be set separately, and the line markings of each pipeline should be clear, eye-catching, and easy to distinguish.

除轉角樁外，當多種線路標識需在同一地點設置時，應只設置一個線路標識，設置順序為里程樁／測試樁、標志樁、通信標石、分界樁。

Except for corner stakes, when multiple line markers need to be set at the same location, only one line marker should be set in the order of mileage stakes/test stakes, marker stakes, communication markers, and boundary markers.

除相同介質的兩條管道同溝敷設外，線路標識均應設置在管道中心線上方，在滿足可視性需求的前提下，可適當縱向調整位置。

Except for two pipelines with the same medium laid in the same trench, line markings should be set above the centerline of the pipeline, and the position can be adjusted longitudinally to meet visibility requirements.

線路標識原則上應設置在路邊、田埂、堤壩等空曠荒地處，減少對土地使用的影響。

In principle, route markings should be set up on open wasteland such as roadsides, ridges, and embankments to reduce the impact on land use.

未作明確說明的線路標識樁正面均應面向來油（氣）方向。

The front of the line identification piles without clear instructions should face the direction of oil (gas) coming in.

當管道埋深較淺，線路標識對管道有影響時，線路標識埋地部分的深度可適當減小，但不應小于0.3米，地面以上的高度保持不變。

When the buried depth of the pipeline is shallow and the route identification has an impact on the pipeline, the depth of the buried part of the route identification can be appropriately reduced, but should not be less than 0.3 meters, and the height above the ground remains unchanged.
