电缆警示桩施工前的准备工作很重要：

Preparation before construction of cable warning pile is very important:

1.详细检查研究放样区的完整施工图。

1. check the complete construction drawings of the setting out area in detail.

2、提前准备好交桩记录所需表格，了解收桩人员的构成，方便沟通。

2. Prepare the forms required for pile delivery records in advance to understand the composition of pile receiving personnel and facilitate communication.

3、准备好符合要求的量具、木桩、记号笔、白石灰等工具。

3. Prepare measuring tools, wooden stakes, marking pens, white lime and other tools that meet the requirements.

4.更正测量和布局需要使用的工具，同时还要保证这些工具必须在规定的有效期内。

4. correct the tools required for measurement and layout, and ensure that these tools must be within the specified period of validity.

相关注意事项：

Relevant precautions:

1、电缆警示桩应安装在管道正上方。电缆警示桩用作角桩时，应安装在角段中点的正上方。管道正上方无安装条件时，可安装在距离道路较近的路边绿化带，并在电缆警示桩上标明管桩的相应意图。

1. The cable warning post shall be installed directly above the pipeline. When the cable warning pile is used as an angle pile, it shall be installed directly above the midpoint of the angle section. If there is no installation condition directly above the pipeline, it can be installed in the roadside green belt close to the road, and the corresponding intention of the pipe pile shall be marked on the cable warning pile.

2、在完全封闭和禁止的道路上不得设置电缆警示桩。电缆警示桩的安装距离应为100m。在地面平坦、视线障碍物少、管线走线直的情况下，电缆警示桩的安装距离可大于100m。在特殊区域，采用特定铺设规范体系铺设管道警示桩！

2. Cable warning posts shall not be set on completely closed and prohibited roads. The installation distance of cable warning pile shall be 100m. When the ground is flat, there are few visual obstacles and the pipeline is straight, the installation distance of cable warning pile can be greater than 100m. In special areas, use specific laying specification system to lay pipeline warning piles!

3、电缆警戒桩沿天然气高压管道埋设，主要材质为塑钢、玻璃钢、复合材料。电缆标有黄色标记并进入警告桩、管道方向、电子巡检信息按钮”，方便巡检人员快速定位管道位置，赢得抢修机会。

3. The cable warning pile is buried along the high-pressure natural gas pipeline and is mainly made of plastic steel, glass fiber reinforced plastic and composite materials. The cable is marked with a yellow mark and enters the "warning post, pipeline direction and electronic Patrol information button" to facilitate the patrol inspectors to quickly locate the pipeline position and win the opportunity of emergency repair.

电缆警示桩施工需要注意的操作：

Precautions for cable warning pile construction:

1、测量放样参考点必须通过GPS定位，其中放样参考点是指设计控制桩和找平桩。

1. The surveying and setting out reference points must be located by GPS, and the setting out reference points refer to the design control piles and leveling piles.

2、控制桩必须按图纸作业要求设置，并注明桩号、里程、地面标高、转角高度等数据。

2. The control pile must be set according to the requirements of the drawings, and the pile number, mileage, ground elevation, corner height and other data shall be indicated.

3、在测量数据和平面图或剖面图上标明地下障碍物。其次，要保证线路与地下结构交叉口两侧的控制范围为3米。同时，必须设置警示标志和警示桩。相关数据必须写在警示牌上。例如：埋深、十字尺寸等。

3. Mark underground obstacles on survey data and plan or profile. Secondly, the control range on both sides of the intersection between the line and the underground structure shall be 3 meters. At the same time, warning signs and warning piles must be set up. Relevant data must be written on the warning board. For example: buried depth, cross size, etc.

4、关于标线，在轴线与警戒桩边界之间拉一根绳子，撒上白石灰标线。完成线路后，现场的障碍物。

4. As for the marking, pull a rope between the axis and the boundary of the warning pile, and sprinkle white lime marking. After completing the line, remove the obstacles on site.

5、移桩方面，在标线完成后，清扫完成前，将所需的管线管桩全部移土墩一侧，范围控制在0.3m以内。

5. In terms of pile moving, after the marking is completed and before the cleaning is completed, all the required pipeline pipe piles shall be moved to the side of the soil pier, and the range shall be controlled within 0.3m.
