1，水泥井盖，水泥井盖是原来用的比较多的，多用于小区和不太明显的一些场合，水泥井盖的优点很明显，造价低，具有主动防盗性，不容易丢失，而且水泥井盖一般比较厚，也比较防盗。缺点是水泥井盖比较笨重，开启相对困难，承载力有限，重车碾压后容易龟裂、掉角。有些井盖盖着完好，打开以后就碎了，下水道堵塞，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开启的检查井。

1, cement shaft cover, cement cover is more used in the original, more used in residential areas and not too obvious on some occasions, the advantages of the cement well cover is very obvious, low cost, with the active anti-theft, not easy to lose, and the cement cover is generally thick, but also more anti-theft. The drawback is that the cement manhole cover is relatively heavy, and the opening is relatively difficult, and the bearing capacity is limited. After heavy vehicle rolling, it is easy to crack and drop. Some of the covers are well covered and they are broken after opening, and the sewers are blocked, most of which are caused by the broken cover of the cement well, so the cement cover is not suitable for roads and often the inspection wells that need to be opened.

2，复合井盖，复合井盖是用非金属材料，中间加以钢筋或竹篾做支撑，制成的井盖，一般有高分子材料，玻璃纤维材料，树脂材料等到，复合井盖有颜色鲜艳，主动防盗等到特点，应用的越来越广泛。缺点是承载力较小，耐腐蚀性较差，网络上曝光的“竹篾井盖”“盖脆脆”指都就是这种井盖。夏天的高温和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，大雨天容易被水冲走，导致行人掉入井口中，出现伤亡事故。

2, compound well cover, the compound well cover is a non metal material, the middle of the steel bar or bamboo strip to support, made of well cover, generally have polymer material, glass fiber material, resin material, and so on, the compound well cover has bright color, active anti-theft and other characteristics, the application is more and more widely used. The shortcoming is that the bearing capacity is small and the corrosion resistance is poor. The net covers of the bamboo covers and the crisp covers are all the covers. The high temperature in summer and the low temperature in winter make the composite manhole aging very fast. Some chemical agents for snow removal are the natural enemies of composite covers. Therefore, the compound well head is not suitable for the areas that are too cold in the north, but also can not be used on large motor vehicle roads. In addition, the composite manhole cover is not connected because of its light weight. It is easy to be washed away by water in heavy rain days, which leads pedestrians to fall into the wellhead and cause casualties.

3，球墨铸铁井盖，球墨井盖的刚性较好，防盗型的采用合页式链接，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，城市主干道路，基本上还是应用球墨井盖比较多。球墨井盖因为有合页链接，下大雨不会移位或冲走，可以说是更加的安全实用，目前发达国家一般只采用球墨铸铁材质的井盖，我国北京，上海、广东、沈阳，长春，天津等一线城市也主要采用球墨铸铁井盖。这种井盖缺点是价格稍贵。

3, ductile iron shaft cover, the rigidity of the ball ink well cover is better, the anti-theft type with the hinge link, relative to the other two kinds of well cover cost slightly higher, but some important high load occasions, such as urban expressway, urban trunk road, basically still use the ball ink well cover is more. Because of the hinge link of the spherical ink well cover, it can not be shifted or washed away from the heavy rain. It can be said that it is more safe and practical. At present, the developed countries usually only use the cover of the ductile iron material. In Beijing, Shanghai, Guangdong, Shenyang, Changchun, Tianjin and other front-line cities, the main use of spheroidal graphite cast iron well cover is also used. The disadvantage of this kind of well cover is that the price is a little expensive.
