Sign piles, also known as warning piles, identification piles, and sign piles, are commonly used as route indication signs for buried pipelines in power, communication, gas, tap water, and railways. A new type of product used for outdoor, green belts, shrubs, and pipeline path indication on both sides of top pipes, serving as a warning.

按用途分為：電纜標(biāo)志樁、油氣標(biāo)志樁、通信標(biāo)志樁、光纜標(biāo)志樁、自來水標(biāo)志樁、鐵路標(biāo)志樁、公路里程樁。主要是根據(jù)產(chǎn)品的用途和上面印刷內(nèi)容分類。

Classified by purpose: cable marker piles, oil and gas marker piles, communication marker piles, optical cable marker piles, tap water marker piles, railway marker piles, and highway mileage piles. Mainly classified based on the purpose of the product and the content printed on it.

按材料可分為：水泥標(biāo)志樁、塑鋼標(biāo)志樁、復(fù)合材料標(biāo)志樁。復(fù)合材料標(biāo)志樁又分為：菱鎂標(biāo)志樁、玻璃鋼標(biāo)志樁、樹脂加沙標(biāo)志樁、樹脂標(biāo)志樁。

According to materials, it can be divided into cement marker piles, plastic steel marker piles, and composite material marker piles. Composite material marker piles are further divided into: magnesite marker piles, fiberglass marker piles, resin Gaza marker piles, and resin marker piles..

管道標(biāo)志樁一般用于水、油、氣等管道的建設(shè)。管道建成后，為了便于對管道的養(yǎng)護(hù)和檢修，依靠沿線設(shè)置的管道標(biāo)記樁找到管道的準(zhǔn)確位置。管道標(biāo)記樁主要包括轉(zhuǎn)角樁、里程樁、保護(hù)測試樁等，穿越鐵路、公路、較大河渠、電纜及其他管道處應(yīng)設(shè)置標(biāo)志樁，對于所有轉(zhuǎn)角都應(yīng)設(shè)置轉(zhuǎn)角樁，管道在線路整處設(shè)置長久標(biāo)志里程樁，有些危險品運輸管道的建設(shè)過程中，管道標(biāo)記樁兼作保護(hù)測試樁。

Pipeline marker piles are generally used for the construction of water, oil, gas, and other pipelines. After the pipeline is completed, in order to facilitate the maintenance and repair of the pipeline, the accurate position of the pipeline is found by relying on the pipeline marker piles set up along the line. Pipeline marker stakes mainly include corner stakes, mileage stakes, protection test stakes, etc. When crossing railways, highways, large rivers, cables, and other pipelines, marker stakes should be set up. For all corners, marker stakes should be set up. Long term marker mileage stakes should be set up throughout the entire kilometer of the pipeline. In the construction process of some dangerous goods transportation pipelines, pipeline marker stakes also serve as protection test stakes.
