如今錯(cuò)綜復(fù)雜的地下管線(xiàn)維護(hù)，就成了不小的難題。今天，我們就來(lái)一起了解地埋警示帶選購(gòu)的3個(gè)關(guān)鍵要點(diǎn)！

Nowadays, the maintenance of complicated underground pipelines has become a big problem. Today, we are going to learn about the three key points for the purchase of buried warning tape!

1、看材質(zhì)

1. Look at the material

深埋地下的壓力管道，大多采用PE管道，這些管道普遍被應(yīng)用于燃?xì)?、水利等基礎(chǔ)設(shè)施建設(shè)之中。為了保護(hù)這些地下管道，減少在施工挖掘時(shí)被不慎挖斷的幾率，避免造成燃?xì)庑孤?、通訊中斷，乃人員受傷等嚴(yán)重后果，地埋警示帶應(yīng)運(yùn)而生。

Most of the buried pressure pipes are PE pipes, which are widely used in gas, water and other infrastructure construction. In order to protect these underground pipelines, reduce the chance of being accidentally cut during construction and excavation, and avoid serious consequences such as gas leakage, communication interruption, and even personal injury, buried warning tapes came into being.

我國(guó)目前實(shí)施的《城鎮(zhèn)燃?xì)鈽?biāo)志標(biāo)準(zhǔn)》就要求，在中低壓天然氣管道安裝的工程中須緊貼管道位置，埋設(shè)可以探測(cè)的示蹤帶，從而方便施工方對(duì)管道進(jìn)行探測(cè)和定位，在管道上方200-300mm處需要鋪設(shè)PE材質(zhì)的保護(hù)板，避免挖掘設(shè)備開(kāi)挖時(shí)管道受損。

The Standard for Urban Gas Signs currently implemented in China requires that the installation of medium and low pressure natural gas pipelines must be close to the pipeline location, and the tracers that can be detected must be buried, so as to facilitate the construction party to detect and locate the pipeline. The protective plate made of PE should be laid at 200-300mm above the pipeline to avoid damage to the pipeline during excavation of excavation equipment.

所以，選購(gòu)地埋警示帶的時(shí)候，材質(zhì)就是不容忽視的關(guān)鍵要點(diǎn)之一。地埋警示帶，就采用了PE管材級(jí)材質(zhì)，這種材質(zhì)常常被用于生產(chǎn)和制作管材，質(zhì)地堅(jiān)硬，耐酸堿腐蝕，使用壽命長(zhǎng)，即便是長(zhǎng)期埋在潮濕的土壤中也不會(huì)腐壞變質(zhì)。

Therefore, when purchasing the buried warning tape, the material is one of the key points that cannot be ignored. The buried warning tape is made of PE pipe material, which is often used to produce and make pipes. It is hard, acid and alkali resistant, and has a long service life. It will not deteriorate even if it is buried in wet soil for a long time.

2、看厚度

2. See thickness

影響一塊地埋警示帶耐沖擊性能的，不僅僅取決于材質(zhì)，還取決于板材的厚度。一些小廠(chǎng)家為了壓縮生產(chǎn)成本，就在板材的厚度上大做文章，生產(chǎn)出的地埋警示帶厚度不達(dá)標(biāo)，這大大影響了地埋警示帶的使用。

The impact resistance of a buried warning tape depends not only on the material, but also on the thickness of the plate. In order to reduce the production cost, some small manufacturers made a big deal in the thickness of the plates, and the thickness of the buried warning tapes produced was not up to the standard, which greatly affected the safety of the buried warning tapes.

在地埋警示帶的厚度、規(guī)格上都精益求精，力求保障產(chǎn)品的性，比如材料密度達(dá)到0.9/cm3,尺寸穩(wěn)定性在35%以下，整體厚度控制在3-5mm左右，這足以保證地埋警示帶抗沖擊性能更加優(yōu)異，能夠?qū)ο路降墓艿佬纬勺銐虻姆雷o(hù)作用。

The thickness and specification of the buried warning tape shall be improved to ensure the safety of the product. For example, the material density shall reach 0.9/cm3, the dimensional stability shall be less than 35%, and the overall thickness shall be controlled at about 3-5 mm, which is enough to ensure that the buried warning tape has better impact resistance and can form sufficient protection for the pipeline below.

3、看印刷質(zhì)量

3. Look at the printing quality

地埋警示帶不僅需要安裝金屬示蹤線(xiàn)，還應(yīng)當(dāng)在表面印刷醒目的圖案和文字，提醒施工單位小心施工，盡量避免施工風(fēng)險(xiǎn)。由于地埋警示帶長(zhǎng)期埋在潮濕悶熱的地下，一旦印刷質(zhì)量不過(guò)關(guān)，就會(huì)給施工帶來(lái)不可預(yù)估的隱患。

The buried warning tape not only needs to be installed with metal trace lines, but also should be printed with striking patterns and words on the surface to remind the construction unit to be careful and avoid construction risks as much as possible. As the buried warning tape is buried in the damp and hot ground for a long time, once the printing quality is not up to standard, it will bring unpredictable potential safety hazards to the construction.

地埋警示帶的性上下足功夫，增添了一些輔助材料來(lái)提升整體的韌性和耐老化性能，表面印刷內(nèi)容采用高溫覆膜技術(shù)，這能夠保證印刷的圖案和文字可以長(zhǎng)久保持鮮艷、醒目，不容易脫落、掉色，影響警示性。

The safety of buried warning tape has been greatly improved. Some auxiliary materials have been added to improve the overall toughness and aging resistance. High temperature film covering technology is used for the surface printing content, which can ensure that the printed patterns and characters can remain bright and eye-catching for a long time, and are not easy to fall off and fade, affecting the warning.

地埋警示帶看似普通，但對(duì)地下管網(wǎng)來(lái)說(shuō)，卻是一道關(guān)重要的防線(xiàn)。倘若您需要選購(gòu)靠譜的地埋警示帶，可以按照以上3個(gè)關(guān)鍵要點(diǎn)來(lái)選擇。當(dāng)然，如果想要節(jié)省選購(gòu)時(shí)間、更加省心省事地搞定采購(gòu)，那不妨來(lái)我們這里http://www.bjhuishi.com看看！
