复合井盖与水泥井盖、球墨铸铁井盖

  复合井盖与水泥井盖、球墨铸铁井盖的特性区别你清楚吗?接下来山东球墨铸铁井盖给大家详细说一下。

  Do you know the difference between composite well cover, cement well cover and nodular cast iron well cover? Next, Shandong nodular cast iron manhole cover will give you a detailed description.

  1,水泥井盖,水泥井盖是原来用的比较多的,多用于小区和不太显着的一些场合,水泥井盖的长处很显着,造价低,具有自动防盗性,不简单丢掉,并且水泥井盖一般比较厚,也比较防盗。缺陷是水泥井盖比较笨重,敞开相对困难,承载力有限,重车碾压后简单龟裂、掉角。有些井盖盖着无缺,翻开今后就碎了,下水道阻塞,多数是由于水泥井盖破碎掉到井里引起的,所以水泥井盖不适合道路以及经常需要敞开的检查井。

  1. The cement well cover and the cement well cover are used in many places. They are mostly used in residential areas and not very significant occasions. The advantages of the cement well cover are very significant, low cost, automatic anti-theft, not easy to lose, and the cement well cover is generally thick and anti-theft. The defect is that the cement well cover is relatively bulky, relatively difficult to open, with limited bearing capacity, and simple cracking and angle dropping after heavy vehicle rolling. Some well covers are intact. They will be broken when they are opened. The sewer is blocked. Most of them are caused by the broken cement well covers falling into the well. Therefore, the cement well covers are not suitable for roads and inspection wells that often need to be opened.

  2,复合井盖,复合井盖是用非金属资料,加以钢筋或竹篾做支撑,制成的井盖,一般有高分子资料,玻璃纤维资料,树脂资料比及,复合井盖有色彩艳丽,自动防盗比及特色,使用的越来越广泛。缺陷是承载力较小,耐腐蚀性较差,网络上曝光的“竹篾井盖”“盖脆脆”指都便是这种井盖。夏天的高温文冬天的低温使复合井盖老化很快,一些除雪的化学制剂更是复合井盖的天敌。所以复合井盖不适合北方太冷的地区使用,更不能用在大型机动车道路上。另外,复合井盖由于自身较轻,没有连接,大雨天简单被水冲走,导致行人掉入井口中,出现伤亡事故。

  2. Composite well covers are made of non-metallic materials and supported by steel bars or bamboo strips in the center. Generally, there are polymer materials, glass fiber materials and resin materials. The composite well covers have bright colors, automatic anti-theft ratio and features, and are used more and more widely. The defects are small bearing capacity and poor corrosion resistance. The "bamboo strip well cover" and "brittle cover" exposed on the network refer to this kind of well cover. The high temperature in summer and the low temperature in winter make the composite well cover age quickly, and some chemical agents for snow removal are the natural enemies of the composite well cover. Therefore, the composite well cover is not suitable for the use in the cold area in the north, not to mention on the road of large motor vehicles. In addition, due to its light weight and lack of connection, the composite well cover is simply washed away by water in heavy rain days, resulting in pedestrian falling into the wellhead, causing casualties.

  3,球墨铸铁井盖,球墨井盖的刚性较好,防盗型的选用合页式链接,相对于其它两种井盖造价略高一些,不过一些重要的高负荷场合,如城市快速路,城市骨干道路,基本上还是使用球墨井盖比较多。球墨井盖因为有合页链接,下大雨不会移位或冲走,可以说是愈加的安全有用,现在发达国家一般只选用球墨铸铁材质的井盖,我国北京,上海、广东、沈阳,长春,天津等一线城市也首要选用球墨铸铁井盖。这种井盖缺陷是价格稍贵。

  3. Nodular cast iron manhole covers have better rigidity, and hinge links are selected for anti-theft type. Compared with other two kinds of manhole covers, the cost is slightly higher. However, in some important high load occasions, such as urban expressway and urban backbone road, nodular cast iron manhole covers are mostly used. Because of the hinge link, the ductile iron manhole cover will not be displaced or washed away in heavy rain, which can be said to be more safe and useful. At present, the developed countries generally only choose the ductile iron manhole cover. The first tier cities such as Beijing, Shanghai, Guangdong, Shenyang, Changchun and Tianjin also choose the ductile iron manhole cover. The defect of this kind of well cover is that it is a little expensive.
