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(biāo)識設(shè)置基本要求

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

相同介質(zhì)的兩條管道同溝敷設(shè)時，線路標(biāo)識宜合并設(shè)置，位置位于兩條管道中間；三條管道同溝敷設(shè)時，應(yīng)分別設(shè)置線路標(biāo)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(zhì)的兩條管道同溝敷設(shè)時，應(yīng)分別設(shè)置線路地面標(biāo)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(biāo)識應(yīng)分別設(shè)置，每條管道的線路標(biāo)識應(yīng)清晰、醒目、便于區(qū)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(zhuǎn)角樁外，當(dāng)多種線路標(biāo)識需在同一地點(diǎn)設(shè)置時，應(yīng)只設(shè)置一個線路標(biāo)識，設(shè)置順序為里程樁／測試樁、標(biāo)志樁、通信標(biāo)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(zhì)的兩條管道同溝敷設(shè)外，線路標(biāo)識均應(yīng)設(shè)置在管道中心線上方，在滿足可視性需求的前提下，可適當(dāng)縱向調(diào)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(biāo)識原則上應(yīng)設(shè)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(biāo)識樁正面均應(yīng)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(dāng)管道埋深較淺，線路標(biāo)識對管道有影響時，線路標(biāo)識埋地部分的深度可適當(dāng)減小，但不應(yīng)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.
