标志桩又称为警示桩、标识桩、标桩，常用于电力、通信、燃气、自来水、铁路地埋管线路径指示标志。用于户外、绿化带、灌木丛、顶管两侧管线路径指示。下面我们就从分类用途特点参数来了解标志桩吧。

Marker piles, also known as warning piles, marker piles, and marker piles, are commonly used to indicate the path of buried pipelines in power, communications, gas, tap water, and railways. It is used for outdoor, green belt, Bush and pipeline route indication on both sides of pipe jacking. Now let's understand the sign pile from the classification, use and characteristic parameters.

按用途分类

Classification by purpose

按用途分为：电缆标志桩、油气标志桩、通信标志桩、光缆标志桩、自来水标志桩、铁路标志桩、公路里程桩。主要是根据产品的用途和上面印刷内容分类。

It can be divided into: cable marker pile, oil and gas marker pile, communication marker pile, optical cable marker pile, tap water marker pile, railway marker pile and highway mileage pile. It is mainly classified according to the purpose of the product and the content printed on it.

按材料分类

Classification by material

按材料可分为：水泥标志桩、塑钢标志桩、复合材料标志桩。复合材料标志桩又分为：玻璃钢标志桩、树脂加沙标志桩、树脂标志桩。

According to the material, it can be divided into: Cement marker pile, plastic steel marker pile and composite marker pile. Composite marker piles are also divided into FRP marker piles, resin Gaza marker piles and resin marker piles.

标志桩特点

Characteristics of marker pile

水泥标志桩：材质是混凝土，部分内部有钢筋。传统材质，字迹容易模糊，需要定期维护。不耐酸，材质较重，运输安装不方便。水泥标志桩塑钢标志桩：材质是塑钢（PVC，聚氯乙烯）。材质轻便，弹性好，耐酸碱耐腐蚀，抗老化性能好。安装运输方便。

Cement sign pile: it is made of concrete, and some of it is internally reinforced. With traditional materials, the handwriting is easy to blur and needs regular maintenance. Acid resistant, heavy material, inconvenient transportation and installation. Cement sign pile plastic steel sign pile: the material is plastic steel (PVC, PVC). Light material, good elasticity, acid and alkali resistance, corrosion resistance, good aging resistance. Convenient installation and transportation.

塑钢标志桩玻璃钢标志桩：经高温压制而成。抗冲击，耐磨损，耐高温，耐腐蚀，可以抗水、汽油、酒精、电解盐、醋酸、盐酸、钠钾化合物、尿、沥青，适合各种酸碱土壤。使用寿命长达30年。内容采用丝网印刷技术，警示效果好，不需要维护。重量轻，便于运输安装。无回收价值，自然防盗。

Plastic steel sign pile glass steel sign pile: it is pressed by high temperature. Impact resistance, wear resistance, high temperature resistance, corrosion resistance, can resist water, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium potassium compounds, urine, asphalt, suitable for all kinds of acid-base soil. The service life is up to 30 years. The content adopts screen printing technology, which has good warning effect and does not need maintenance. Light weight, easy to transport and install. No recycling value, natural anti-theft.

一些其他参数：

Some other parameters:

玻璃钢标志桩

FRP marker post

1、拉伸强度≥160MPa

1. Tensile strength ≥ 160MPa

2、弯曲强度≥190MPa

2. Bending strength ≥ 190mpa

3、浸水后弯曲强度≥150MPa

3. Bending strength after immersion ≥ 150MPa

4、巴氏硬度≥38

4. Babbitt hardness ≥ 38

5、环钢度（5%）≥50KPa

5. Ring stiffness (5%) ≥ 50kPa

6、热变形温度≥160℃

6. Thermal deformation temperature ≥ 160 ℃

7、氧指数26%

7. Oxygen index 26%

地埋标志桩高温压模一次成型，抗冲击、耐磨损、耐高温、耐腐蚀，使用寿命可达50年。表面采用凹刻处理，字体图案清晰美观。防偷盗。是一种兼顾玻璃钢标志桩和水泥标志桩优点的产品。树脂加沙标志桩树脂标志桩：纯树脂制作，成本非常高，一般不常用。

The buried sign pile is formed by high-temperature die at one time, which is impact resistant, wear-resistant, high-temperature resistant and corrosion-resistant, and its service life can reach 50 years. The surface is etched, and the font pattern is clear and beautiful. Prevent theft. It is a product that takes into account the advantages of FRP marker pile and cement marker pile. Resin Gaza marker post resin marker post: made of pure resin, the cost is very high, and it is generally not commonly used.
